Conversation
Conversation memory embeds passages with llama.cpp, next to the completion engine. The pending CotabbyInference patch gains CotabbyEmbeddingEngine: its own model and context (embeddings on, the model's pooling), texts packed into one decode per batch and the cells cleared after each, so memory use is fixed by the batch size. Measured with Qwen3-Embedding-0.6B Q8_0: about 38 mail-sized passages per second at a flat ~880 MB with a 1024-token batch, and vectors within cosine 0.9996 of sentence-transformers. llama.cpp's backend is process-wide, so both engines now share it through a reference-counted guard; unloading one no longer frees the backend under the other. This needs the matching change in FuJacob/cotabbyinference; until then it rides in patches/cotabbyinference-upstream-pending.patch like the other pending APIs. A cancel is a generation counter, noted before a call waits for the lock, so a cancel issued while a call is still waiting is not lost.

The core of an optional, on-device memory of the user's conversations, with no source and no UI yet: - MemoryStore keeps messages, conversations, participants, sync cursors and one vector per passage in SQLite. Text, names, titles, ids, cursors and vectors are sealed with MemoryVault (AES-256-GCM, subkeys from a 256-bit Keychain key that never syncs); lookups and record ids use HMAC tags. Timestamps, sources and the settings file are plain. - MemoryEngine is the ingest pipeline every source shares (exclusions, retention, mail quote stripping, secret and one-time-code scrubbing), background indexing (newest first, each vector persisted as it is computed, so a run resumes), and the scoped search: the conversation the window names, then only conversations with exactly the same people; an unknown, partial or ambiguous title returns nothing, and a scope can require the thread to have exactly given people (a mail reply's quoted addresses, as far as memory knows them), which also picks the right audience among a mail thread's conversations. A mail sender's display name never becomes a participant. A stopped engine refuses further writes. - Search is hybrid: an exact half-precision vector scan with Accelerate (FlatVectorIndex, filtered before scoring, so a scoped search never comes back short) fused with BM25 over HMAC-tagged terms. - EmbeddingCore wraps the inference package's embedding engine; queries jump ahead of background batches. EmbeddingSchedulePolicy lets small deltas run anytime and keeps backlogs to a plugged-in, idle, cool Mac outside Low Power Mode; nothing runs while a suggestion is generating. - MemoryEngineController owns on/off, the pinned embedding model download (Qwen3-Embedding-0.6B Q8_0, pinned to a repository commit, size and SHA-256 checked) and the key. The Keychain store of typing history gains a label so memory's item is named for what it is.

One read-only reader per source, each paging after a cursor it defines, driven by MemoryHistorySync (when a source is switched on, on demand, and every 15 minutes on AC power). Nothing is fetched from a network and no account API is used: - WhatsApp: its ChatStorage database. - Apple Mail: the Envelope Index plus .emlx files, parsed by EmailBodyExtractor (charsets, quoted-printable, HTML-only mail). Mail is attacker-controlled, so parsing is bounded and linear: message, header, boundary, nesting and part limits, and HTML converted in one pass instead of regular expressions that rescan from every unclosed tag. Mail counts as the user's own only when it sits in a Sent mailbox, and junk is skipped, so a spoofed From cannot put words in the user's mouth. - Outlook: the classic database, and New Outlook's HxStore.hxd (LZ4 blocks and HxStoreRecordParser), including meeting invitations. HxStore records have no thread id or recipients, so a conversation there is one topic with one sender, never a subject alone; the user's own mail and mail without a sender each stay a conversation of their own. In Mail and classic Outlook a message without a thread id is its own conversation, never a shared bucket. Mail clients join threads by References/In-Reply-To and subject, which any sender controls, so a Mail or classic Outlook conversation is one thread with one audience (MailAudience): a stranger folded into a thread, or a reply with someone new on it, is another conversation. Mail people are addresses, never display names or Reply-To, and only Mail's Sent mailbox or Outlook's outgoing flag makes a message the user's own. - Microsoft Teams: the new client's cache, read natively in place (Snappy, LevelDB, Chromium IndexedDB and V8 value readers, a Swift port of parts of CCL Forensics' MIT-licensed ccl_chromium_reader) and mapped by TeamsMessageMapper. Group chats (Teams and WhatsApp) carry a marker of their own, so they never share memory with a 1:1 chat or another group. - Calendar: events through EventKit, as records without call boilerplate; the user is never a participant. - A documents folder (text and Markdown), and iCloud Drive, Google Drive and OneDrive documents (PDF, Word, PowerPoint, Excel, RTF, text), with a bounded ZIP reader and total-size caps for Office files. A running sync can be cancelled and awaited (cancelSync), and stopping the schedule cancels it; a cancelled sync drops the page it was reading with its cursor, so after a delete nothing comes back and nothing is skipped. The protected stores need Full Disk Access; the access check opens only the files of these sources. Reading an online-only cloud document makes the drive's app download it. Reader tests use synthetic fixtures built in the tests. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01BWE41JyPDYvSWqdCX5EM69
Conversation memory reaches the autocomplete prompt: - ConversationScopeResolver turns the focused app and window title into a scope (the chat name or mail subject, within the app's enabled memory sources; Teams titles are parsed for the open chat) and a stable query of complete 8-word blocks. A subject does not say who a mail is for, so a mail gets memory only as a reply or forward, from a thread with exactly the people the client's quote header names (only the first header block: addresses in the quoted body are the sender's own text and could name another thread's people). - MemoryRetriever implements the new SuggestionMemoryProviding: it answers from its cache and never makes a suggestion wait; a stale query starts a background lookup, and when new lines land for the conversation in focus while nothing is shown, the coordinator offers a suggestion that uses them. Lookups log memory_ms, memory_engine_ms, memory_hits and memory_scope. - Requests carry memorySnippets; the base prompt gets an "Earlier in this conversation:" recap (priority 39, all or nothing) and Apple's prompt a framed equivalent that marks them as quoted messages, not instructions. A contact's name cannot start a line or pass for "You". - Memory never reaches the endpoint engine: the retriever returns nothing for it, the request factory blanks it, and the router drops any request still carrying it (memoryWithheldFromEndpoint). - The router counts generations in flight, which memory's indexing reads to stay off the GPU while a suggestion is being generated. - The recall suite gains a memorySnippets field and five memory cases where the fact the completion needs is only in an earlier message; COTABBY_EVAL_NO_MEMORY=1 runs them without memory as the baseline.

- Settings -> Memory: the on/off switch with the embedding model download, status and recovery from a key mismatch; Full Disk Access guidance (macOS has no prompt for it: the row opens the list, reveals this copy of Cotabby, and re-checks when Cotabby becomes active); Sources with readiness, counts, Sync Now and Forget per source, and Calendar access; Index settings and statistics (size on disk, vector memory, search and query-embedding latency, indexing rate); Privacy (retention, never-remember lists, Delete All); and a Playground that shows what memory retrieves for a conversation and can add it to the never-remember list. Forget and Delete All cancel and await the source's sync before deleting. - CotabbyAppEnvironment builds the controller, sync, control model and retriever once, hands the retriever to the suggestion coordinator and has indexing wait while the router is generating; AppDelegate starts memory only when the user left it on and stops it on quit. Sources sync when the engine starts and every 15 minutes on AC after that. - Reading events under the hardened runtime needs the Calendars resource-access entitlement and a usage string. The app now has a checked-in Cotabby.entitlements that Xcode, the local signing helper, kickstart and the release workflow all sign with, so a re-sign keeps it. Everything is off by default: memory, and each of its sources. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01BWE41JyPDYvSWqdCX5EM69
ARCHITECTURE.md gains the memory data flow, its privacy rules and the shared llama.cpp backend; AGENTS.md the subsystem's owners and the rules a change must keep; SOURCE_LAYOUT.md the new folders; the README the feature, what it reads and stores, and the optional Full Disk Access and Calendars permissions.

The audience check ignored quoted addresses memory did not know, so a stranger could copy a thread's people and subject into their own mail's quote header and the reply to them drew on that thread. Now every address in the client's quote header, less the addresses the user sends from, must equal the thread's people; an unknown address is someone else and gives no memory. The mail readers report the user's own addresses (the senders of sent mail per account in Mail, of outgoing mail in Outlook), and the store keeps them as HMAC tags per source. An own address memory has not learned yet counts as someone else, which is the safe side.

…asses a nonisolated deinit CI's Xcode 26.3 rejected `abs(number) < 1e15` in V8ValueDeserializer as ambiguous: with Accelerate imported elsewhere in the module, older compilers see more than one `abs`. The key conversion now uses `magnitude` and explicit types, and the BM25 idf terms call `Foundation.log` with an explicit Double. On the macOS 26 runtime, releasing a main-actor class that has no nonisolated deinit goes through the back-deployment main-actor shim, which over-releases and crashes the test host. MemoryControlModel, MemoryEngineController, MemoryHistorySync and MemoryRetriever get a nonisolated deinit (their state is safe to release from any thread), as SuggestionSettingsModel and EmojiUsageStore already do, and the controller's StatusRelay is nonisolated.

Xcode 26.3's compiler gave up on IndexedDBReader.makePrefix in the test
build ("unable to type-check this expression in reasonable time"). Swift
6.4 accepts it quickly, so every multi-operator integer expression, range
check chain, `reduce` byte assembly and literal-led `+` array chain in the
memory readers and their tests is now built in typed steps: shift and
mask values in typed lets, byte reads in loops, range checks as `switch`
cases, and test fixtures joined through a `concat` helper instead of `+`.
Behaviour is unchanged.

Xcode 26.3 spent about a second type-checking `beginObserving()`'s untyped Task closure. The Task is now typed and the loop body lives in `pollOnce()`, which also stops the closure holding `self` across the sleep between refreshes.

Review follow-ups on the engine, its store and the pieces around them: - The retriever drops its cached lines whenever the engine's new data generation moves (forget, delete all, never remember, settings, a deleted or shortened document), and a lookup started before lands nowhere, so a deleted message never reaches a prompt. - Ingest and every removal or settings change share one write lock, so an ingest filtered with old settings cannot restore a purged conversation. - Indexing saves a message's vectors only if it is unchanged since it was read, re-checks the schedule between native calls, and keeps only messages embedded whole when it stops early. - A re-read message that moved to another conversation or changed owner is updated, and a conversation left empty is removed. - Pointing the Documents Folder source at another folder forgets the old folder's records and cursor, after stopping its sync. - A mail reply's quote header is the first header of the whole field, so header-like text after the caret in an inline reply is never read. - The controller drops engine starts made stale by a stop or a newer start, and stored memory can be deleted while memory is off. - Playground results come from the newest search only; the engine's status callback is read under its lock; the Full Disk Access text names every source that needs it.

Review follow-ups on the source readers: - Mail's .emlx map is rebuilt when mail newer than the map needs its file, instead of living as long as the app and losing new mail. - The Documents Folder reader reports notes read whole and the notes still there, so edited-out paragraphs and deleted notes leave memory. - A cloud drive or notes listing that could not read every account or folder removes nothing, and a cloud file that could not be read (offline) is tried again on the next sync instead of being left behind the cursor. - With retention bounding the window, a calendar series with a change is read whole, so a moved occurrence leaves memory. - Teams maps each profile on its own and no longer guesses the user on a tie (by who wrote more). - LevelDB per-entry sequences wrap instead of trapping on a damaged header, DocumentSections cuts a huge paragraph in linear time and stops at the section limit, and the HxStore String helper is nonisolated.

Security review follow-ups. Quote header: the parser now reads a header only where the mail client puts it. The field is normalized first (line breaks, NFKC, invisible format characters removed). Nothing above the caret may look like a header or a quote, so inline replies and pasted headers give no memory. The first header-like line after the caret must be one the parser reads, at the quote boundary. An attribution or From line names exactly one address. Quoted-printable or HTML remnants, or a second header block right after the first, give none. Cache: the data generation moves before any rows are removed, replaced or moved (the store calls back) and again after. The retriever checks it and reads or writes its caches inside the engine's withDataGeneration, so a removal cannot begin between the check and the write. A lookup keeps its result only if the generation is the one read before it started. Caches are emptied while memory is off and are keyed by the engine's instance id, so a new engine never serves an old one's lines.

Every scope derived from a mail's body can be shaped by the other person: their display name and text are part of the quote. So a mail reply no longer gets conversation memory by parsing the body. ConversationScopeResolver drops the quote-header parser and the mail-subject path: Apple Mail and Outlook get no scope. The engine drops the quoted-audience match (requiredParticipants, isSameAudience, the own-address table and its ingest plumbing; an existing table is dropped) and never resolves a title in a mail source. MailAudience still isolates threads in the store, mail still syncs, and the Playground can search it. Mail-reply memory waits for the compose window's own To/Cc fields, which the sender cannot write.

- A whole number beyond Int's range in config.json stays a Double (Int(exactly:)) instead of trapping at launch. - FlatVectorIndex.remove moves the last row in place instead of passing a slice of the buffer to its own replaceSubrange (a full copy per row). - The document readers page by when a file changed or arrived (the later of its modification and status-change times), so a file moved, renamed or synced in with an old date is still read; records keep their own date. - A corrupt Teams blob index beyond Int's range throws instead of trapping. - Purge (and a whole-file re-read) removes the conversations and people it empties, so an excluded person leaves no sealed name or tag behind. - Index settings are clamped (overlap at most half a passage) in the pane on every edit and before they are applied.

The cloud cursor follows a file's later modification or status-change time, so a file moved or renamed in with an old date still arrives. But reading an online-only file downloads it and gives it back, and giving it back moves the status-change time past the cursor: every sync on AC would download it again. The cursor now also keeps (hashed) the files this reader read while they were online-only. While such a file is still online-only, only its modification time counts, so an edit brings it back and our own eviction does not. Every other file keeps the arrival rule, including one moved or renamed in (a new id). Cursors written before stay readable. The test fakes the file attributes, since File Provider placeholders cannot be made in a test.

Every memory sync decoded and parsed the whole HxStore.hxd, then kept the few messages inside the two-day look-back. On a real 276 MB store (45,731 records) that took 16 to 58 s of a full core at launch and every 15 minutes on AC power, to add no mail. - HxStoreScanCache keeps, per stretch of the file, a digest of its bytes and what reading it gave: a record's block and the fields needed to pick each message's fullest version, or a gap with the offsets whose header looked plausible. The next scan reuses a stretch only where the bytes digest the same at the same offset, and tries a gap's plausible headers again (a record Outlook was still writing can complete past later records), so the result is a full scan's whatever Outlook rewrote. Digests are a seeded 4-lane xxHash64 round (about 10 GB/s); the cache lives in memory only (48 bytes per segment). - Bodies are converted only for messages sent after the cursor's look-back (sentAfter), not for the whole mailbox. - Memory syncs run at background priority, on the efficiency cores. Measured on a drive catching up, reading was as fast as at utility. - "Outlook store scanned" is logged with records, reuse and seconds. On the real store the first scan took 11.7 s and the next 0.6 s, reusing 45,517 of 45,753 records (98% of the bytes). Not done: skipping the scan when the file's size and modification time are unchanged. A write through a shared mapping updates the modification time only when it is flushed, so that could miss new mail. Tests: an incremental scan equals a full scan after records are added at the end, rewritten in place, written into a gap, cut off and completed, completed past later records, and after the file shrinks or is replaced; an unchanged file decodes nothing; a future time becomes a send time once plausible; sentAfter; the digest. Checked by breaking the digest check and the gap recheck: each made tests fail.
On a real Google Drive (3,905 documents, 3,199 online-only) each sync
read about 350 unchanged files, downloading each, for 5 to 8 minutes of
CPU and network until its run budget ran out, then did it again.
- A file the reader has seen before changes only when it is modified. Its
status-change time also moves whenever its content is downloaded or
given back (by this reader, the user, or the drive freeing space) and
when the drive updates its records: 3,523 of the 3,905 files had a
status-change time within a day, all with old modification times. A
file not seen before still arrives by its status-change time, so one
moved in with an old date is read. The cursor keeps the last complete
listing as 8-byte SHA-256 prefixes in one base64 string; a cursor
without it takes the current listing, so the update does not read the
whole drive again. This replaces the list of files the reader gave
back, which covered only its own evictions.
- A file read with no text in it (a scanned or locked PDF, an empty file)
is done until it changes. It was retried on every sync like a file that
could not be read: 138 such files cost about 150 s per sync, each
downloaded and parsed again. DocumentTextExtractor.extract tells text,
no text, and unreadable (with the error, for the log) apart.
- A sync whose last page reads nothing still hands its earlier pages'
failures to the next sync; they waited forever before.
- A file the drive still holds right after the read ("in use") is given
back again a moment later; 4 of 138 evictions failed that way and left
the download behind.
- The cloud drive and Documents readers list their folders once per
sync: liveConversationIDs reuses the listing the read just took.
- "Cloud drive read" is logged with files listed, read, without text,
unreadable (with errors) and retried.
Measured on the real drive: Google Drive went from 325 to 470 s per sync
to 0 s (after one sync reading the 138 text-less files once more), iCloud
Drive from 6 to 7 s to 1 to 2 s, Documents from 4 to 5 s to 1 s.

ScanPass decodes a record and builds its summary before hashing the mapped bytes. If Outlook rewrites the record between those steps, the cache pairs the old summary with the new bytes' digest. Later scans then reuse that stale summary.
A record changed from an old send time to a recent one can remain excluded by sentAfter until another write or an app restart. Hash before decoding and verify the bytes again afterward. Cache the result only when both hashes match.

An intermediate page saves the incoming seen set without adding the new files it just read. When a new online-only file is downloaded and given back, its status-change time moves forward. The next page lists it again, still treats it as unseen, and downloads it again.
A large batch can keep cycling through these files across pages and saved cursors. Add each attempted file to seen before saving an intermediate cursor, while keeping unreadable files in the retry sets.

The ending cursor replaces seen with listed even when listing.isComplete is false. The empty-page path does the same. If an account or folder is temporarily unreadable, this forgets that its files were already seen.
When the folder returns, unchanged files whose status-change times moved past the cursor are treated as new and downloaded again. Preserve the earlier seen keys on incomplete listings, and replace the set only after a complete listing.

Review comments at @CotabbyTests/Fixtures/llama-recall-cases.json:
- Around line 425-445: Update the memory-mail-amount-01 fixture to use a
memory-capable application and bundle, such as Microsoft Teams, and remove the
mail-specific greeting from precedingText so the case reflects a prompt users
can actually receive. If retaining a mail-shaped case for future To/Cc scope
support, tag it for separate reporting instead.
Review comments at @CotabbyTests/Support/Memory/ConversationMemoryTests.swift:
- Around line 113-126: Update
test_memorySectionSitsInTheBasePromptAboveTheCaretText to throw, and use
throwing XCTUnwrap calls for both the memory-section range and the caret range.
Remove try? and force unwraps so missing prompt text fails the test cleanly.

- Around line 60-62: Move the single Swift files from Calendar, Embedding, and
Index directly under Cotabby/Services/Memory, remove those folder entries from
SOURCE_LAYOUT.md, and regenerate Cotabby.xcodeproj so its references reflect the
new layout.

Discard out-of-date conversation loads.
loadConversations writes every result to playgroundConversations. It does not check whether that result is still the newest request. The Playground calls loadConversations each time sourceID changes. neverRemember also calls it with the old conversation.source. Suppose the user switches the source picker while an earlier load is still running. The earlier result can then finish last and replace the list for the newly selected source. The picker then lists conversations from the wrong source until the user changes the source again. Use the same generation guard that runSearch uses.

Make the next start() wait for the previous engine to stop.
The comment on Lines 42-43 says two engines never run or hold the store at once. stop() breaks that rule:
stop()setsstartTask = nil.stop()returns a detached task that callsengine?.stop()and awaits the pending start.start()readsprevious = startTaskon Line 199. After a stop, that value isnil.restart()and a quicksetEnabled(false)→setEnabled(true)therefore start a newMemoryEnginewithout waiting.
The new engine can run beside the old engine while the old engine is still unloading, or beside a stale start that is still building its engine. Each engine opens MemoryStore on messages.sqlite and loads the 0.64 GB embedding model. During that overlap, two models stay resident, and a cancelled indexing loop can still write vectors.
deleteMemoryData() already awaits stop(). Give start() the same ordering. Store the stop task and await it in start().

Mask the blob subdirectory to one byte, as Chromium does.
Chromium names a blob's directory from the second byte of the blob number only. GetBlobDirectoryNameForKey formats (blob_number & 0xff00) >> 8 with %02x. This code formats blobNumber >> 8 without the mask, and that value grows past one byte. For blob number 0x10005, Chromium uses .../00/10005 and this code builds .../100/10005.
As a result, readFile returns nil and blobContents throws missingBlob. forEachValue then counts the record as undecodable and skips it. Large reply chains are stored as blobs, and blob numbers grow over time in a long-used Teams profile. Long-time users therefore lose messages from memory without any notice.
%02x with a UInt64 argument also depends on how varargs are laid out. The mask removes that dependency.

Decode entities in one pass so the output is the same on every launch.
decodeEntities iterates over the named dictionary. Swift seeds dictionary iteration order randomly for each process. Input &lt; therefore becomes < on some launches and < on others. The result depends on whether & is replaced before or after <. The numeric pass then decodes the output of the named pass a second time, so &#60; always becomes <.
This matters in the store. MemoryStore.upsert detects an unchanged message by text_tag, which is a tag of the body text. If the body text changes between launches, an unchanged mail counts as edited. The store then rewrites it and drops its vectors and terms, and indexing runs again.
A second defect is in the same function. The pattern accepts hex digits for decimal references. On input such as ab;, UInt32(..., radix: 10) fails. The code then writes nothing, so the reference is deleted instead of being left as written.

Update decodeEntities to decode named and numeric entities in a single
left-to-right pass over the original text, so decoded output is not processed
again and results are deterministic. Restrict decimal references to decimal
digits, support the existing hexadecimal form, and preserve the original entity
when its numeric value is invalid.

The list editors remove Return and trailing spaces while the user types.
The TextEditor setter splits the text on \n, trims whitespace and removes empty lines on each keystroke. The getter then joins the result again. Two failures follow:
- The user types Return after "alice". The setter receives
"alice\n"and stores["alice"]. The editor shows"alice"again. The user cannot start a second line. - The user types a space after "John". The space is trimmed at once, so the user cannot type "John Smith" in "Never remember people".
The UI tells the user to enter "one id per line" and "names or addresses, one per line". Typing cannot do this. Only pasting works. These fields control privacy exclusions, so this blocks a privacy workflow. SuggestionRequestFactory documents the same problem: "trimming on every keystroke would prevent the user from typing a space".
Keep the raw text in @State while the user edits. Convert it to the list when the user presses Apply.

Move the memory-mail-amount-01 case off a mail bundle.
This case sets bundleIdentifier to com.apple.mail and injects memorySnippets. In production, a mail field never gets memory. ConversationScopeResolver.scope returns nil for every entry in mailBundleIdentifiers, and test_aMailReplyWithAPerfectQuoteHeaderGetsNoMemory confirms this behavior. As a result, the recall suite scores a prompt shape that users never receive, and the memory recall rate does not match real behavior.
Use a bundle that can carry memory, such as Teams or WhatsApp. If the goal is to keep a mail-shaped case for the future To/Cc scope, tag it so that it is reported separately.

Replace try? and force unwraps with throwing XCTUnwrap.
Line 120 discards the XCTUnwrap failure with try?. Line 123 then force-unwraps memory! and caret!. Suppose the renderer stops emitting the "Earlier in this conversation" section. The test then traps and does not fail cleanly. A trap in the app-hosted runner stops the test run, so the remaining tests do not report.
