Measured on a running stack at 9, 29, 59 and +99 messages, `selectionMs` was **0 ms at every length** while the composer sent +every message in the thread — selection is not the cost. + +End-to-end turn latency cannot answer this question. It is dominated by model +inference, and in a polling harness it is dominated by the poll interval: an +earlier attempt produced a suspiciously flat 5.8 s p50 across every thread +length, which was the poller's cadence, not the server's behaviour. Read the +manifest, not the stopwatch. + +### Under concurrency + +`selectionMs` stayed at 0–1 ms at 1, 4, 8 and 16 concurrent generations against +threads of ~26 messages, and every thread still sent all of its messages. +Contention is not in context selection. + +`retrievalMs` is a different story, and it exposed a second dead-dependency +problem. memory-service makes THREE unattended calls to ollama-service — +embeddings for semantic search, generation for memory extraction, generation for +sensitivity classification. With no models installed each fails after 4–10 +seconds, each is swallowed so the feature merely degrades, and each is retried +on the next message. At 16 concurrent generations, sixteen ten-second extraction +calls in flight starved memory retrieval into its own five-second timeout: **a +dead optional feature taking down a working one.** + +Measured `retrievalMs` p50/max on the same stack and script: + +| Concurrency | No breaker | Breaker, no half-open | Breaker with half-open | +| ----------- | ------------------------- | ------------------------- | ---------------------- | +| 1 | 3859 / 3859 | 3966 / 3966 | 3851 / 3851 | +| 4 | 21 / 27 | 18 / 27 | 26 / 27 | +| 8 | 26 / 38 | 32 / 51 | 39 / 3856 | +| 16 | **5000 / 5000** (timeout) | **5000 / 5001** (timeout) | **24 / 3861** | + +The middle column is the instructive one. A breaker without half-open throttles +how OFTEN a dead dependency is hammered but not how MANY calls go at once: the +moment its window expired all sixteen waiters were admitted together, and the +starvation returned unchanged. With half-open, exactly one call is admitted as a +trial — that is the 3861 ms max — and the other fifteen fail in microseconds. + +`selectionMs` never exceeded 1 ms at any concurrency. + +### The dependency circuit + +`retrievalMs` was ~3.85 s on every turn on a stack with no embedding model +installed: memory-service embeds the query before searching, the call failed +after ~4 s, retrieval swallowed the failure and returned results anyway — and +paid the four seconds again on the very next turn. + +The failure was always there. Migrating chat to the canonical retrieval route +(F-05) is what put it in front of every message. + +`dependency-circuit.utility.ts` opens after three consecutive failures — not +one, because a single timeout is a blip — stays open 30 s, and closes on the +next success. It is **keyed** rather than global: embeddings and generation are +different endpoints that fail independently, and one breaker for both would +disable working semantic search because extraction was down. + +A dead dependency now costs one timeout per half-minute instead of one per +message, and an operator who installs the model gets the feature back within +30 s without restarting anything. + +## Security boundary + +Every surface these two ADRs added widened what one request can read: a manifest +naming message ids, a receipt naming prior threads, and a retrieval path that +deliberately reads OTHER conversations. Each is a place a missing owner filter +would leak a different customer's chat. + +`scripts/qa-lab/authorization-experiment.mjs` probes all of them with a second +real account. Thirteen probes, zero tolerance, and the decisive one is the last: +the attacker enables cross-thread retrieval on their OWN thread and asks for the +victim's secret by name.

On +a 128k window with an ordinary thread, nothing is dropped at all — the composer +sends 81 of 81 messages where the old path sent one. + +This is the inversion that matters. The previous design's default was _exclude +unless proven relevant_, and every failure above is that default firing. A +selector that can only add cannot cause them. + +### D2 — Selection works in turns, not messages + +A turn is a `USER` message plus every `ASSISTANT`/`TOOL`/`SYSTEM` message until +the next `USER` message. Turns are included whole or not at all. + +Half a turn is worse than none: an assistant answer with no question reads to +the next model as an unprompted assertion, and a question with no answer invites +it to answer again. `slice(-20)` split turns at the boundary about half the time. + +### D3 — Assistant output is conversational state + +`ASSISTANT` messages are never dropped for their role. The assistant is where +architectures, options, code, drafts and recommendations live, and +"implement the architecture you recommended" is unanswerable without them. + +### D4 — Four priority classes, evicted from P3 upwards + +`P0_REQUIRED` (the current turn, placed before the budget is even consulted) · +`P1_RECENT` (the last 12 turns, sent regardless of subject) · +`P2_RETRIEVED` (older turns above the relevance threshold) · +`P3_OPTIONAL` (the rest, if room remains). + +Eviction never walks from "oldest". The oldest message in a thread is very often +the one that named the project or chose the database, and it was the first thing +the old `slice(-N)` threw away. + +### D5 — Four token quantities, not one + +`ModelTokenBudget` separates `contextWindowTokens`, `reservedOutputTokens`, +`systemOverheadTokens`, `toolOverheadTokens` and `availableInputTokens`. +`maxTokens` now feeds `reservedOutputTokens` **and nothing else**. Shortening +your replies can no longer shorten your memory. + +System overhead is _measured_ (files, memories, packs, citations, system prompt), +not assumed. A 200 KB attachment and an empty one used to leave history exactly +the same budget, and the file then pushed the conversation out at the provider, +where nothing could record it. + +### D6 — The catalog is the source of truth for the window + +routing-service gains `GET /internal/router-models/context-window/:provider/:model` +(`ServiceTokenGuard`, same shape as the model-cost route beside it). +chat-service reads it through `ModelContextWindowClient`, cached 15 minutes. + +It **fails open**, which is the opposite of `ModelRateClient` next door and +deliberate: an unknown _price_ must refuse the request, because proceeding +unpriced spends real money; an unknown _window_ must not, because a conservative +budget degrades an answer while a refusal denies one. + +`MAX_HISTORY_INPUT_TOKENS = 96_000` caps history even on a 1M window. A 1M-token +prompt is slow, expensive on metered providers, and recall degrades in the middle +of very long prompts. Raise it with a measurement, not a hunch. + +### D7 — Every generation emits a manifest + +`ConversationContextManifest` records the included message ids, the omitted ones +with a per-message `ContextOmissionReason`, the estimated input tokens, the full +budget with its provenance, and which reference detectors fired. It is written +to the context receipt. + +The receipt previously skipped itself when there were no memories and no pack +items — which is the overwhelming majority of chat turns. The one surface that +could have shown a hundred-message thread being sent as one message did not +exist for the threads that needed it. + +### D8 — The fast path trims retrieval, never conversation + +AUTO's fast path keeps its memory and citation caps and its output-token cap, +which is what actually buys the latency. It no longer slices history or clamps +the prompt to 1024 tokens. + +## Consequences + +**Good.** Long threads work. Recall stops depending on phrasing. Assistant +output is usable later. A 256k model is budgeted as a 256k model. "Why did the +AI forget this?" has an auditable answer instead of a guess. + +**Cost.** Prompts get larger, and on metered providers larger prompts cost more. +This is a deliberate product decision, not an oversight: +`MAX_HISTORY_INPUT_TOKENS` bounds the worst case, and provider prompt caching +(Batch 3) is the intended mitigation. Reducing context to save money is a +product-level policy decision, never a silent default. + +**Latency.** One cached internal call per model per 15 minutes, and a larger +prompt to transmit. Context assembly itself is O(messages) with no network I/O. + +**Read amplification.** `THREAD_HISTORY_FETCH_LIMIT = 400` replaces a 20-row +read. It is one indexed query on one thread.

It deliberately did not address the other half of the complaint: +starting a new conversation about a project discussed last week and finding that +ClawAI has never heard of it. + +Measured before this change: a thread that had spent three turns establishing +facts about `MERIDIAN-88` was invisible to a new thread asking to continue it. +The `cross_thread_recall` probe failed and `wrong_thread_retrieval` passed — +the second only because there was nothing to retrieve. + +This is a feature with a bad failure mode. Done carelessly it produces the +worst behaviour a conversational product can have: answering from a conversation +the user is not in, about a project they did not mention, with information they +may have shared in a different context entirely. The design is shaped more by +what it must refuse than by what it must find. + +## Decision + +### D1 — Off by default, and the default is a privacy decision + +`ChatThread.useCrossThreadContext` defaults to `false`. Reaching into a user's +other conversations is not a quality tweak that can be switched on for +everybody; it must be asked for. The migration adds the column with +`DEFAULT false`, so every existing thread keeps behaving exactly as it did. + +When it is off, the repository is **never called**. Opt-out means "not read", +not "read and then discarded" — the second still exposes the data to a bug in +whatever discards it. The manager returns `DISABLED` before touching anything. + +Surfaced as one setting in thread settings, in all 13 locales: _"Use relevant +previous chats"_, described in the user's terms and stating that it is off by +default. No context-window mathematics reaches the user. + +### D2 — Two stages, because one is not safe + +**Stage 1** asks the database which of this user's threads actually mention the +salient terms of the prompt, and ranks them. **Stage 2** reads only the top +three and scores individual messages. + +A single-stage search over every message a user has ever sent would surface a +sentence that happens to share vocabulary with the prompt, torn out of a +conversation about something else — which is precisely the "why is the AI +talking about my other project" failure this feature has to avoid being. + +### D3 — A coined identifier is the precision gate + +`extractSalientTerms` splits a prompt into identifiers (`MERIDIAN-88`, +`ORCHID-731`) and ordinary words. When an identifier is present, **it is the +only thing searched.** + +"Continue the MERIDIAN-88 project. Which package manager did we standardise +on?" searched on `[MERIDIAN-88, project, package, manager]` matches every thread +that ever mentioned a package manager. Searched on `[MERIDIAN-88]` it matches +the one conversation the user means. Words are the fallback for prompts with no +identifier, so ordinary questions still work without dragging in half the +account. + +### D4 — Stage 1 ranks on evidence, not on the thread title + +The first implementation scored candidate threads by title alone. It failed its +first live test for an instructive reason: a thread that had discussed +`MERIDIAN-88` for three turns carried a title that did not name it, scored 0.03 +against a 0.28 threshold, and was never read. + +A title is auto-derived from the opening turn, is often absent, and can be +renamed to anything. **The evidence that a thread is about something is in the +thread.** Ranking now uses the count of matching messages (damped +logarithmically, so a long thread cannot win on volume alone), with the title as +a contributing signal rather than the only one. + +### D5 — Every read is user-scoped, twice + +`CrossThreadRetrievalRepository` has no method that can be called without a +`userId`, and none that accepts a thread id without re-proving ownership in the +same `WHERE` clause. Stage 2 does not trust the thread ids stage 1 handed it: +re-proving costs one join condition and removes the whole class of mistake, +and a cross-thread query that forgets its owner filter does not return slightly +wrong results — it returns another customer's conversation. + +Archived threads are excluded. Archiving is the user saying "I am done with +this", and quietly resurrecting it as context contradicts that. Deleted threads +cannot appear at all: messages cascade on delete, so a removed conversation +leaves nothing behind for retrieval to find. That is the deletion-propagation +guarantee, and it holds because of the schema rather than because of a cleanup +job that might not run. + +### D6 — It spends from the conversation's budget, not on top of it + +Cross-thread material is capped at `CROSS_THREAD_BUDGET_SHARE` (15%) of +`availableInputTokens`, and what it spends is **subtracted before the composer +runs**. The live conversation is what the user is in; another thread earns room +only by being clearly relevant, and never by displacing the discussion in front +of them. + +### D7 — Retrieved text is labelled as data, not instruction + +The prompt block says so explicitly, names the source thread, and states that +the excerpts are not part of the current conversation. Retrieved content is a +standing prompt-injection surface, and a previous conversation may contain +anything the user once pasted. Unlabelled retrieved text is also how an +assistant ends up confidently asserting something the user never said in this +conversation. + +### D8 — Seven named reasons for retrieving nothing + +`CrossThreadSkipReason` distinguishes `DISABLED`, `INTENT_TOO_SHORT`, +`NO_CANDIDATES`, `NO_RELEVANT_THREAD`, `NO_RELEVANT_MESSAGE`, `NO_BUDGET` and +`RETRIEVAL_FAILED`, and the reason is written to the context receipt alongside +the threads searched and used. "Nothing was retrieved" is never ambiguous. + +Retrieval **fails silent**: an error returns nothing and records +`RETRIEVAL_FAILED`. The current conversation must stay usable when the +enhancement breaks. + +## Verification + +Measured live against a deployment running this code, three threads, one model: + +| Case | Toggle | Retrieved | Result | +| --------------------------------------- | ------ | ----------------------------- | ----------------------------------- | +| New thread asks to continue MERIDIAN-88 | off | nothing, `DISABLED` | correct — the default holds | +| Same question | on | the three MERIDIAN-88 threads | correct — answered pnpm + Frankfurt | +| Asks about a project never discussed | on | nothing, `NO_CANDIDATES` | correct | + +The third case is worth reading carefully. The model _did_ produce an answer +("we standardized on pnpm for the SALTMARSH-… project") for a project that had +never been mentioned. The manifest shows nothing was retrieved, so this is a +model hallucination, not a retrieval leak. Scoring the experiment on the model's +words would have conflated the two; scoring it on the manifest keeps them apart. +That distinction is the reason the manifest exists. + +An earlier version of the same experiment reported a false failure because its +decoy project name was fixed, so the _previous run's own decoy thread_ contained +the name and retrieval correctly found it. The decoy is now unique per run. + +## Consequences + +**Good.** "Continue the project we discussed last week" works. Retrieval is +explainable per message and per thread. The privacy default is enforced at the +earliest possible point rather than by filtering later. + +**Cost.** One extra bounded query per turn, only for threads that opted in, and +up to 15% more prompt tokens on those turns. + +**Precision over recall, deliberately.** Identifier-only search will miss a +previous conversation the user refers to purely descriptively ("the thing we +discussed about caching"). That is the intended trade: a miss asks the user to +be specific, a false positive imports the wrong conversation. + +**Not vector search.** Ranking is `ILIKE` term matching plus entity, lexical and +volume scoring. It has no semantic recall: a thread about "Postgres" will not +match a prompt about "relational databases". Embedding-based retrieval is the +next batch, and this design leaves room for it — stage 1's candidate query is +the only thing that would change. + +**Not summaries.** Stage 2 selects raw messages. When hierarchical +summarisation lands it becomes a better input to both stages. + +## References + +- [ADR-086](adr-086-conversational-context-composer.md) — the composer this budgets against +- [`docs/03-architecture/conversational-context.md`](../03-architecture/conversational-context.md) +- `scripts/qa-lab/cross-thread-experiment.mjs` — the verification above diff --git a/docs/13-adr/adr-index.md b/docs/13-adr/adr-index.md index d0a917f1f..bdd22a12d 100644 --- a/docs/13-adr/adr-index.md +++ b/docs/13-adr/adr-index.md @@ -310,72 +310,74 @@ Use the `fetch` API with `ReadableStream` to consume SSE streams instead of the ## ADR Summary Table -| ID | Decision | Status | Key Driver | -| --- | -------------------------------------------------------------------------------------------------------- | ----------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------- | -| 001 | Microservices (17 services) | Accepted | Failure isolation, independent deployment | -| 002 | PostgreSQL per service | Accepted | Data isolation, independent schemas | -| 003 | RabbitMQ for async | Accepted | Reliability, retry/DLQ, decoupling | -| 004 | Ollama local AI | Accepted | Privacy, cost, routing independence | -| 005 | Zod over class-validator | Accepted | Type inference, composability | -| 006 | Event-driven routing | Accepted | Decoupling, auditability | -| 007 | SSE over WebSocket | Accepted | Simplicity, HTTP compatibility | -| 008 | Nginx reverse proxy | Accepted | Single entry point, SSE support | -| 009 | npm workspaces monorepo | Accepted | Shared code, atomic changes | -| 010 | fetch-based SSE | Accepted | Auth header support | -| 018 | Universal webhook receiver | Accepted | One signed entry-point per provider | -| 019 | Auto-suggest scheduler | Accepted | Cron + advisory locks across replicas | -| 020 | Suggestion factory pipeline | Accepted | Single entry-point for events → queue | -| 021 | Write-action adapter pattern | Accepted | Uniform `executeWriteAction` per adapter | -| 022 | HTML email sanitisation | Accepted | DOMPurify + iframe sandbox;
