From 8e7e1d1a0535b24cc6c2c1d7645907190d5f3fe6 Mon Sep 17 00:00:00 2001 From: Yash Datta Date: Sun, 25 Oct 2026 16:53:45 +0800 Subject: [PATCH 01/13] =?UTF-8?q?feat:=20loop=20watches=20=E2=80=94=20CI?= =?UTF-8?q?=20failures=20and=20review=20comments=20start=20repair=20runs?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `codeoid loop watch …` polls GitHub through the owner's `gh` login and starts loop runs on its own: when mapped CI checks fail on a watched branch (or one of the owner's pull requests), or when an allowed author comments @codeoid on the owner's PRs. Runs repair the branch the event happened on, from a clean checkout of its head commit. - Trust rule: a head runs only when every commit past the default branch was written by someone the owner trusts; quoted lines, code and HTML comments are stripped before a mention counts; each event acts once across all of an owner's watches; one repair per branch at a time; per-watch hourly cap; rate-limit backoff; a run whose workspace couldn't be prepared gives its event back, three tries in all. - Contract gains baseRef (commit, branch, repo, fetch ref, trusted) and trigger (kind, key, url, summary). The event text reaches the worker only as a quoted data block, in the first prompt and a takeover's. - A review comment's run doesn't stop "blocked" when its checks already pass (they guard the change), and says so when the worker changed nothing. - Setup recipe copies (an .env) only land next to a commit off the owner's history when the watch vouched for it (copyNeedsReviewedBase); a setup command that didn't run is a workspace.note in the run's history. - A head that isn't local is fetched from GitHub by URL into a repository the daemon makes for the fetch, borrowing the owner's objects, so the repository's agent-writable config (url rewrites, proxies, TLS settings, credential helpers) has no say over it; https only, gh as the only credential helper. It is the only daemon git with the network on (hardenedGit's new `network` option names the one protocol allowed); the fetched pack is indexed into the owner's repository offline by hardened git. createForkWorktree's baseCommit resolves with hardened git. - loop.watch.{create,list,get,update,delete,poll} authorized like loop.* (owner-only; create/change/enable/poll need session:approve and refuse delegated tokens; pause and delete are safety stops). CLI, terminal formatting, web loop detail, settings (loops.watchPollSeconds), docs.

A comment on one of your open pull requests — on a line, on the conversation, or a review's own text — that contains `@codeoid` (`--mention` to change it), is by an allowed author, and was made after the watch was created or last resumed. + Comments made while a watch was paused don't start runs when you resume it. + Up to two minutes of clock difference between GitHub and your machine is allowed on that comparison. + Allowed authors default to the account `gh` is signed in as; `--allow ` names others. + Only what the author wrote themselves counts, and only that reaches the run: quoted lines (`>`), code, and HTML comments are left out, so quoting someone else's `@codeoid …` asks for nothing. + +### What a triggered run works on + +- Its worktree is a clean checkout of the branch head the event happened on, never your current checkout and never your uncommitted changes. +- A head that isn't in your repository is fetched from `https://github.com/.git` by URL, not through `origin`, and not in your repository at all: into one the daemon makes for the fetch under its own directory, which borrows your repository's objects so only what's missing is downloaded. + Your repository's configuration, which an agent can write, has no say over where the fetch goes or what it presents (no url rewrite, proxy, TLS setting, or credential helper of yours applies). + The fetch's own configuration is the only one: no global or system config, https only, no ssh or proxy command, and `gh auth git-credential` as the only credential helper, so private repositories work with the login the watch already uses. + This is the only git the daemon runs with the network on; what it fetched is then added to your repository's objects offline, by the same hardened git as every other loop step. + A failed fetch says why in the run's reason. + A run whose workspace couldn't be prepared gives its event back, and the watch tries it again on later polls, three times in all. +- The delivered commit sits on the run's own `codeoid/loop-…` branch, on top of that head; push it to the pull request yourself. +- A repository's [setup recipe](CONFIGURATION.md) copies its files (such as `.env`) into the worktree, because the head passed the trust rule. + Its trusted setup command does not run on a commit that isn't on your checkout's history, such as most pull request heads; the run's history says so, and the checks then run without what that command would have installed. +- `codeoid loop show` names what started a run, with a link to the check or the comment. +- A review comment's run whose worker changed nothing ends `blocked` and says so. + +### How a watch stays bounded + +- Each event starts at most one run, across all of your watches: its key (the commit and check run, or the comment and its kind) is recorded with the run it started, and stays recorded when the watch is deleted. +- One repair at a time per branch, across all of your watches on the repository; an event on a branch whose run is still going is skipped and picked up by the first poll after that run ends. +- A watch starts at most 6 runs an hour (`--per-hour`), and its runs count against your limit of three runs in progress; an event skipped for either is tried again on a later poll. +- A failure on a commit a loop delivered (its subject starts with `codeoid loop:`) is ignored for good, so a loop can't keep repairing its own output. +- Check output and comment text are task data: a run's objective is fixed text, and the event's text reaches the worker only inside a quoted data block, truncated to 4,000 characters. + The terminal prints it with escape sequences and control characters removed, and links only to github.com. +- A branch that can't be read (deleted, renamed) is a problem for that branch alone; the watch's other branches are still polled. +- You can have 10 watches. + Comments are read from ten minutes before the last complete poll, not from the beginning each time. + When GitHub rate-limits a watch (HTTP 403 or 429), it backs off: two poll intervals, then four, doubling up to six hours, until a poll gets through. +- `gh` runs with only `PATH`, `HOME`, and its config location in its environment, never the daemon's credentials, and with a timeout; a failed poll is recorded on the watch (`show` displays it, naming the GitHub endpoint) and the next poll tries again. + +Watches poll every `loops.watchPollSeconds` seconds (default 300, at least 60), and a few seconds after the daemon starts or a watch is made or resumed. +They cost nothing between polls. +Making, changing, resuming, or polling a watch needs the same scopes as starting a loop and can't be done with a delegated token; pausing and deleting it are safety stops that can. + +### Limits of a watch's authority + +- **One person per daemon.** + A watch reads and fetches from GitHub as the daemon's `gh` login, so watches belong to one person. + Once someone has a watch, nobody else can make one on that daemon until theirs are gone. +- **A watch keeps acting after your credential is revoked.** + Your scopes are checked when you make, change, resume, or poll a watch, not each time it starts a run, the same as for [routines](routines.md). + The daemon has no way to ask ZeroID whether a credential it saw earlier is still valid, so revoking your token does not stop a watch. + Pause or delete it (any credential that can see it may) when access should end. + ## What is and isn't enforced yet - The worker cannot mark a run done: completion requires every check to pass on the snapshot the daemon took. diff --git a/packages/protocol/src/loops.ts b/packages/protocol/src/loops.ts index 9b34225d..2dff4340 100644 --- a/packages/protocol/src/loops.ts +++ b/packages/protocol/src/loops.ts @@ -82,6 +82,19 @@ export interface LoopRunWire { createdAt: string;

design §4, §10). + * + * A watch is an owner's opt-in rule that turns repository events into + * ordinary repair runs: + * + * - a CI check that failed on a watched branch's head, when its name (and + * the app that reported it) maps to a local command — the run repairs that + * branch until the command passes; + * - a comment on the owner's pull request that addresses codeoid (default + * `@codeoid`) from an allowed author — the run makes the change while the + * mapped commands keep passing. + * + * The watch is an adapter, not a second controller: it decides whether to + * start a run and LoopService does everything else, under the owner's + * identity and the owner's run cap. What it guards: + * + * - Trust: a run executes the code at the head it works on (its checks run + * it). A head fires only when every commit past the default branch was + * authored and committed by a login the owner trusts — gh's own login, + * plus the watch's `trust` list.

"not created yet"} From c194b66256463ae838bece5b22ef2c291bacf3b1 Mon Sep 17 00:00:00 2001 From: Yash Datta Date: Sun, 25 Oct 2026 17:27:25 +0800 Subject: [PATCH 02/13] fix: apply round-2 audit to loop watches - Trust: a head is trusted when GitHub's repository activity records a trusted login pushing it onto its branch (the fork's, for a fork PR), or when every commit past the default branch is signed, verified, and committed by a trusted login (web-flow only when verified and the author is trusted). Commit logins from email matching no longer vouch for anything. - Comments edited more than 5s after they were made are ignored for good; review bodies are read over GraphQL for lastEditedAt. - A skipped review comment is kept as a retry row so `since` stays pinned; retry rows on a closed PR or older than a week expire. - Shallow and partial clones are refused before fetching, and not retried. - Fetch hardening: alternateRefsCommand=true, no lazy fetch, no redirects, fsckObjects, no maintenance/gc, index-pack --strict streamed from the file, 2 GiB pack cap, remote-tracking tips as haves. - commitsBetween needs every commit; only real rate limits back off, shared per gh login; a changed gh login pauses the watch. - Branch mode ignores fork PRs; a watch changed mid-poll starts nothing; a failed bind releases its claim; CI keys use check run + suite ids.

From 683c9d4f7aea4144d5625666c67150735d99eb96 Mon Sep 17 00:00:00 2001 From: Yash Datta Date: Sun, 25 Oct 2026 17:54:29 +0800 Subject: [PATCH 03/13] fix: apply round-3 audit to loop watches Trust: a push or a pr_merge / merge_queue_merge recorded as a trusted login's vouches for the head; web-flow commits never count on the signature path (and web-flow can't be named in --trust); an empty compare range is untrusted; a head GitHub's activity doesn't list yet is judged again for ten minutes before it is recorded untrusted. Comments: line and conversation comments are read through GraphQL by the node ids REST lists, with publishedAt as when they were made and any lastEditedAt as an edit (no grace window); pending review content is excluded, so a batched review's drafted comments fire once it is submitted. Review bodies use publishedAt and exclude pending reviews. Minor: the rate-limit back-off starts over after any poll that wasn't rate-limited; an edited comment waiting to retry becomes ignored; the fetch's haves come only from remotes that are github.com/ and that no insteadOf rewrites; the 2 GiB pack bound is documented as checked after the download (git has no client-side cap), bounded meanwhile by the timeout. docs/loops.md states what trusting by pusher implies.

A button merge by a trusted login vouches as before. An auto-merged pull request (or one GitHub can't say about) and any merge queue merge vouch only when a trusted login turned auto-merge on / queued it and the pull request's final head is itself trusted by push or signatures, with no further merge recursion. - --trust takes bot logins (name[bot]); github-merge-queue[bot] and web-flow stay refused. --allow still takes people only. - GraphQL comment reads use the answer when every error is NOT_FOUND (a comment deleted after REST listed it), skipping those nodes. - Comment nodes carry repository { nameWithOwner } and must be the watched repository's. - The fake gh models GitHub's merge, merge queue, auto-merge and NOT_FOUND behavior; the merge queue test uses github-merge-queue[bot] as actor.

Before a run starts, the watch asks GitHub who made the push that put the head on its branch, from the repository's activity (for a pull request from a fork, the fork's). GitHub records the account that authenticated, so a push by a trusted login vouches for the head, whatever its commits say. -A merge puts the pull request's merge commit at the head of the branch it merged into, and the watch finds that pull request: the one GitHub merged as that commit, into that branch. +A merge puts the pull request's merge commit at the head of the branch it merged into, and the watch finds that pull request: the one GitHub merged as that commit. +The activity already says which branch the merge landed on, so the pull request's own base isn't compared to it. +That is what makes stacked pull requests work: GitHub merges each one in a stack onto its parent's branch and then fast-forwards the default branch, so the pull request named at the default branch's head has its parent's branch as its base. A pull request a trusted login merged with the button vouches for the head, like a trusted push. An auto-merged one doesn't by that alone: GitHub records whoever turned auto-merge on as the merger, and anyone with write access can push commits after that, which GitHub then merges. A merge through the merge queue doesn't either: GitHub records its bot as the actor of every merge queue merge, and the pull request names who queued it. So an auto-merged or queued pull request vouches for the head only when a trusted login turned auto-merge on or queued it, and its final head commit is itself trusted: pushed onto its branch by a trusted login, or every commit on it signed and verified by one (a merge one level further down doesn't count). Otherwise the head is untrusted, with why, for example "auto-merged; its last commit was pushed by @someone". When GitHub doesn't say whether auto-merge was ever on for a pull request, it is judged as auto-merged. -A merge queue merge can land a batch of pull requests at once, and GitHub names only the last as the one merged at the head; when that one is vouched for, the batch vouches for what's beneath it, like a trusted push. +GitHub can take a moment to link a merge commit to its pull request, or to list the push of the pull request's head: like a push it doesn't list yet, the head is judged again for ten minutes. + +A merge vouches for what it merged, not for what was already on the branch beneath it. +A collaborator you don't trust can push straight to the branch, and your pull request merging on top of that push doesn't make their code yours. +So a merge vouches for the head only when what it landed on (the branch's head just before it, which GitHub's activity records) is itself vouched for, one level down: the branch had nothing before (its first push), or this watch already judged that head trusted, or the newest activity that put it on the branch is a push by a trusted login or a pull request a trusted login merged with the button (not auto-merged or queued). +That one level isn't followed any further. +When none of those holds, the merge vouches for nothing and the head falls to the signature rule below, which the default branch itself never passes. +A merge queue merge can land a batch of pull requests at once, and GitHub names only the last as the one merged at the head; when that one is vouched for, the rest of the batch is trusted with it, but what's beneath the batch (the branch's head before the queue merged it) must itself be vouched for, as beneath any merge. A trusted push vouches for every commit beneath the head too, including commits someone else wrote that you pulled and pushed on: pushing a branch is how you say its code is yours to run. The names on a commit vouch for nothing by themselves: GitHub ties a commit to an account by its email, which anyone can write into a commit. So when the push wasn't by a trusted login, or GitHub has no record of it, the head is trusted only if it has commits past the default branch (at most 250) and every one is signed, verified by GitHub, and committed by a trusted login. A head with no commits past the default branch — the default branch itself, or a head it already contains — has no signature to vouch for it, so only a trusted push or merge does. A commit committed by `web-flow` never counts: GitHub signs those for its web buttons (merge, rebase, update branch) whatever author the commit names, and the author is the commit's own say-so; what vouches for a button press is the activity record of who pressed it. GitHub's activity can lag a push by a few minutes: a head it doesn't list yet is judged again on each poll for ten minutes before it is recorded untrusted, and a comment on it waits to retry meanwhile. -The activity only reaches back to 2023, and the watch reads its newest 100 entries for the branch, so a head pushed before that falls to the signature rule. +The activity only reaches back to 2023, and the watch reads its newest 100 entries for the branch, so a head pushed before that falls to the signature rule, and what a merge landed on that far back is vouched for only when the watch already judged it trusted.

What follows from trusting by who pushed: +- `gh pr merge` without `--match-head-commit ` merges whatever the pull request's head is when GitHub gets the request, and a collaborator can push to it just before; GitHub records you as having merged it either way, and doesn't say whether the head moved. + Pass `--match-head-commit` with the head you reviewed, so a head that moved makes the merge fail instead. - Anything that holds your `gh` login or a personal access token of yours pushes as you, and so is trusted as you: a script, a CI job, a tool or another agent you gave the token to. Keep such tokens out of automation you wouldn't let run code on your machine. - A push by a bot or app (a CI autofix, a formatter bot, Dependabot) is not a push by you: its head is untrusted unless every commit on it is signed by a trusted login, which a bot's commits aren't. diff --git a/src/daemon/loops/triggers/github.ts b/src/daemon/loops/triggers/github.ts index 7c39cc64..0671ec85 100644 --- a/src/daemon/loops/triggers/github.ts +++ b/src/daemon/loops/triggers/github.ts @@ -301,11 +301,22 @@ export interface PushRecord { actor: string | null; /** `push`, `force_push`, `branch_creation`, `pr_merge`, `merge_queue_merge`, … (GitHub's activity types). */ type: string; + /** The branch's head before it: {@link NO_COMMIT} for the branch's first push; "" when GitHub doesn't say. */ + before: string; } +/** What GitHub's activity writes as `before` for a branch's first push: nothing was there. */ +export const NO_COMMIT = "0".repeat(40); + /** What GitHub's activity says about a head: the push that made it, if listed, and whether GitHub keeps activity for the repository at all. */ export interface PushLookup { push: PushRecord | null; + /** + * The newest activity before `push` that left the branch at `push.before`: + * how what the push landed on got there.

A trusted merge is one where every commit it put on the branch (first parents down to its `before`) is the merge commit of exactly one merged pull request in the watched repository, and each of those pull requests passes: a button merge whose GraphQL mergedBy is the activity's trusted actor, or an auto-merged or queued pull request merged by trusted logins whose final head is itself trusted. Stacks and merge queue batches have every pull request judged; a rebase merge's earlier commits are counted against its pull request's commit count. The walk reads at most 3 activity pages (cursor-paged via the Link header), 30 changes, 20 commits per merge and 60 in all; anything else falls back to the signature rule. A watch now judges every head it watches on its first poll after it is made, resumed, or given a new trust list, and remembers the ones vouched for. The one-level "beneath" rule is removed, along with the tests that allowed what it let through.

Otherwise the head is untrusted, with why, for example "auto-merged; its last commit was pushed by @someone". When GitHub doesn't say whether auto-merge was ever on for a pull request, it is judged as auto-merged. GitHub can take a moment to link a merge commit to its pull request, or to list the push of the pull request's head: like a push it doesn't list yet, the head is judged again for ten minutes. -A merge vouches for what it merged, not for what was already on the branch beneath it. -A collaborator you don't trust can push straight to the branch, and your pull request merging on top of that push doesn't make their code yours. -So a merge vouches for the head only when what it landed on (the branch's head just before it, which GitHub's activity records) is itself vouched for, one level down: the branch had nothing before (its first push), or this watch already judged that head trusted, or the newest activity that put it on the branch is a push by a trusted login or a pull request a trusted login merged with the button (not auto-merged or queued). -That one level isn't followed any further. -When none of those holds, the merge vouches for nothing and the head falls to the signature rule below, which the default branch itself never passes. -A merge queue merge can land a batch of pull requests at once, and GitHub names only the last as the one merged at the head; when that one is vouched for, the rest of the batch is trusted with it, but what's beneath the batch (the branch's head before the queue merged it) must itself be vouched for, as beneath any merge. +What this means for a branch other people also merge to, such as a team's default branch: + +- List everyone who merges to it with `--trust`. + Otherwise each merge by someone not listed leaves every later head on that branch untrusted, until a trusted login pushes to it or the chain reaches the head the watch last trusted. +- When you make or resume a watch, or change its trust list, its next poll judges every head it watches, and remembers the ones it trusts; being made trusts nothing by itself. + The remembered head is what lets a later chain stop short of the 30-change bound, so a branch that moves a lot is best watched from a head the watch trusts. +- Turn on branch protection for the branch, so changes to it come through reviewed pull requests rather than direct pushes. +- `--my-prs` is unaffected: your pull requests' heads are judged by who pushed them, and a trusted push vouches for everything beneath it. + A trusted push vouches for every commit beneath the head too, including commits someone else wrote that you pulled and pushed on: pushing a branch is how you say its code is yours to run. The names on a commit vouch for nothing by themselves: GitHub ties a commit to an account by its email, which anyone can write into a commit. So when the push wasn't by a trusted login, or GitHub has no record of it, the head is trusted only if it has commits past the default branch (at most 250) and every one is signed, verified by GitHub, and committed by a trusted login. A head with no commits past the default branch — the default branch itself, or a head it already contains — has no signature to vouch for it, so only a trusted push or merge does. A commit committed by `web-flow` never counts: GitHub signs those for its web buttons (merge, rebase, update branch) whatever author the commit names, and the author is the commit's own say-so; what vouches for a button press is the activity record of who pressed it. GitHub's activity can lag a push by a few minutes: a head it doesn't list yet is judged again on each poll for ten minutes before it is recorded untrusted, and a comment on it waits to retry meanwhile. -The activity only reaches back to 2023, and the watch reads its newest 100 entries for the branch, so a head pushed before that falls to the signature rule, and what a merge landed on that far back is vouched for only when the watch already judged it trusted. +The activity only reaches back to 2023, and the watch reads the newest 100 entries for the branch to find who pushed a head (300 to follow a merge's chain), so a head pushed before that falls to the signature rule. Anything else and the head is ignored for good: `show` lists it as ignored, "not pushed by someone you trust", with why, and a later poll doesn't ask again. Changing a watch's trust list (`loop.watch.update`) judges its ignored heads again, and forgets the heads it judged trusted. diff --git a/src/cli.ts b/src/cli.ts index 654ac625..0f023ce5 100644 --- a/src/cli.ts +++ b/src/cli.ts @@ -1706,7 +1706,7 @@ watch .option("--review", "Also start a run for a PR comment that mentions codeoid") .option("--allow ", "GitHub login whose comments count (repeatable; default: you, as gh is signed in)", collect, []) .option("--mention ", "The token a comment must contain (default @codeoid)") - .option("--trust ", "Another GitHub login whose commits may be on a head the watch runs; a bot as name[bot] trusts anyone who can make that bot push (repeatable; you are always trusted)", collect, []) + .option("--trust ", "Another GitHub login whose commits may be on a head the watch runs; list everyone who merges to a watched branch.

A poll re-reads the watch before every rememberTrusted, ignore, and baseline clear after an await, and skips them when it changed; the fire path remembers after the stale-poll check. The baseline stays while any judgment is transient. - --trust-head (loop watch add, update, resume; trustHead on loop.watch.create/update): you vouch for each watched branch's current head, remembered under the current generation, audited, and kept in the watch's history ("you vouched for main at abc123"). Never implied. - Every poll judges a watched branch's moved head and remembers it when trusted, so the remembered head keeps up with the branch. - GraphQL logins are read with __typename: a Bot gets its [bot]. - An auto-merged pull request whose final head was pushed before a trusted login last turned auto-merge on is vouched for. - A hole in the activity is crossed (at most three per chain) at a pull request merged with the button by a trusted login; the reason names the range read only when the record would be past it. - Commits beneath a merge commit are taken as a rebase's only when they and the merge commit are single-parent and match the pull request's commits' messages and author dates, in order. - Docs: --trust-head, web-UI pushes count as your push.

Only branches of the watched repository itself are followed this way: a merge on a fork's branch names no pull request of the watched repository. Then the head falls to the signature rule below, which the default branch itself never passes. A merge is trusted when every commit it put on the branch is the merge commit of exactly one merged pull request in the watched repository, and each of those pull requests is trusted. A commit that two merged pull requests both name as their merge commit vouches for nothing, since which of them put it there can't be told.

A pull request's own base branch isn't compared to the branch: in a stack most pull requests are based on another one's branch. A pull request merged with the button is trusted when the login that pressed it is trusted, and GitHub records that same login as having merged it. An auto-merged one isn't by that alone: GitHub records whoever turned auto-merge on as the merger, and anyone with write access can push commits after that, which GitHub then merges. A merge through the merge queue isn't either: GitHub records its bot as the actor of every merge queue merge, and the pull request names who queued it. So an auto-merged or queued pull request is trusted only when a trusted login turned auto-merge on or queued it, and its final head commit is itself trusted: pushed onto its branch by a trusted login, or every commit on it signed and verified by one (a merge one level further down doesn't count). +An auto-merged one (not queued) is also trusted when GitHub's activity records the push of its final head as earlier than the last time auto-merge was turned on, and a trusted login turned it on then. +Whoever turned it on had that head in front of them: a later push by someone with write access would be recorded later, and GitHub turns auto-merge off when someone without write access pushes.

When GitHub doesn't say whether auto-merge was ever on for a pull request, it is judged as auto-merged.

What follows from trusting by who pushed: - `gh pr merge` without `--match-head-commit ` merges whatever the pull request's head is when GitHub gets the request, and a collaborator can push to it just before; GitHub records you as having merged it either way, and doesn't say whether the head moved. Pass `--match-head-commit` with the head you reviewed, so a head that moved makes the merge fail instead. +- A push you make through GitHub's web UI is your push, and vouches for everything beneath it like any other: "Update branch" on a pull request, committing a review suggestion, editing a file on github.com, and creating a branch there. + "Update branch" merges or rebases the base branch into the pull request's branch, so pressing it vouches for whatever is on the base at that moment. - Anything that holds your `gh` login or a personal access token of yours pushes as you, and so is trusted as you: a script, a CI job, a tool or another agent you gave the token to. Keep such tokens out of automation you wouldn't let run code on your machine. - A push by a bot or app (a CI autofix, a formatter bot, Dependabot) is not a push by you: its head is untrusted unless every commit on it is signed by a trusted login, which a bot's commits aren't. diff --git a/packages/protocol/src/loops.ts b/packages/protocol/src/loops.ts index 2dff4340..8dd0c863 100644 --- a/packages/protocol/src/loops.ts +++ b/packages/protocol/src/loops.ts @@ -277,19 +277,27 @@ export interface LoopWatchWire { /** An event a watch acted on: a run it started, or one it ignored for good. */ export interface LoopWatchTriggerWire { key: string; - kind: "ci_failure" | "review_comment"; + /** An event, or `trust_anchor`: you vouched for a branch's head (`trustHead`). */ + kind: "ci_failure" | "review_comment" | "trust_anchor"; branch: string; runId: string | null; - /** `retry`: its run's workspace couldn't be prepared; a later poll tries again. */ - outcome: "run" | "ignored" | "retry"; + /** `retry`: its run's workspace couldn't be prepared; a later poll tries again. `vouched`: a trust anchor. */ + outcome: "run" | "ignored" | "retry" | "vouched"; note: string | null; createdAt: string; } +/** + * `trustHead` (branch watches only): you vouch for each watched branch's head + * as it is now.

After its --check gate finds work, the routine starts the loop as its owner through LoopService with a `routine` trigger (routine id/name, routine run id; gate output and payload as data), so the run shows in `loop ls` and the loops panel like any other. The routine run follows the loop (loopRunId/loopStatus) without holding a run slot and ends with its outcome; a fire while its last loop run is in progress, or past the owner's loop cap, is skipped. Loop routines need what loop.start needs, and settings a loop can't honour are refused.

Only the visible tab's store polls at the view's pace. Routines: list (schedule in words, next fire, state, gate, last outcome), detail (definition, next fires, recent runs with outcomes, session and loop run links, cancel, run now with payload, pause/resume, API token rotation shown once, delete), and a create/edit form with a live preview of the next three fires from routine.preview, the check gate, approvals, budgets, and the "starts a loop" action (acceptance checks and loop limits; the settings a loop routine refuses step aside and say why). Edits send only what changed. Watches: list (repo, branches or my PRs, health, last poll, error/back-off, runs started), detail (CI mappings, review, trust, history with why a head was refused), create form, trust editor that explains widening vs narrowing (narrowing forgets vouched heads, behind a confirm), and a vouch dialog that pins each branch to a commit (compare-and-set) and re-asks when it moved. State in state/routines.ts and state/watches.ts mirrors state/loops.ts: reset on a new connection, cleared on a refused read, background refresh for the inbox, which now lists failing watches and routines. Loop runs started by a routine link back to it.
