From d37126783e0feab4f9b90092bed33d555680f160 Mon Sep 17 00:00:00 2001 From: Senad Date: Wed, 14 Oct 2026 18:35:50 +0200 Subject: [PATCH 01/16] Add an in-process embedding engine to the inference patch 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.

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.

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.

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.

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.

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.

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.
