OAuth metadata advertises both confidential methods. Pinned by `test/e2e/serve-http-oauth.test.ts`. - `src/core/operations.ts` — Contract-first operation definitions (the foundation). Exports upload validators `validateUploadPath`, `validatePageSlug`, `validateFilename`, plus `matchesSlugAllowList(slug, prefixes)` (glob matcher: `/*` matches recursive children; bare `` matches exact only). `OperationContext.remote` is a REQUIRED field flagging untrusted callers; `OperationContext.allowedSlugPrefixes` is the trusted-workspace allow-list set by the dream cycle; `OperationContext.auth?: AuthInfo` is threaded through HTTP dispatch for scope enforcement in `serve-http.ts` before the op runs. OAuth `whoami` exposes the authenticated `AuthInfo.sourceId` and `AuthInfo.allowedSources` grants as `source_id` and `federated_read`; absent grants serialize fail-closed as `null` and `[]`, while local, legacy, and stdio response shapes stay unchanged. `enforceSubagentSlugFence(ctx, slug, opName)` is the shared fail-closed subagent write fence: when `viaSubagent` and `allowedSlugPrefixes` is set, the slug must match the allow-list; else the legacy `wiki/agents//...` namespace check applies. Both `put_page` and `add_timeline_entry` (subagent-allowlisted) route through it. Auto-link skipped only when `remote=true && !trustedWorkspace`. Every `Operation` carries `scope?: 'read' | 'write' | 'admin'` + `localOnly?: boolean`; `sync_brain`, `file_upload`, `file_list`, `file_url` are `admin + localOnly` (rejected over HTTP). Four trust-boundary call sites (`put_page` allowlist, file_upload trust-narrowing, submit_job protected-name guard, auto-link skip) use FAIL-CLOSED semantics: `ctx.remote === false` for trusted-only sites, `ctx.remote !== false` for "untrust unless explicit-false" — anything not strictly `false` is treated as remote (closes the HTTP MCP shell-job RCE where a read+write OAuth token could submit `shell` jobs). `sourceScopeOpts(ctx)` encodes the source-scoped read precedence ladder — federated array (`ctx.auth.allowedSources`) wins over scalar (`ctx.sourceId`/`ctx.auth.sourceId`) over nothing; every read-side op handler routes through it so a source-bound OAuth client can't see neighboring sources via `search`/`query`/`list_pages`/`get_page`/`find_experts`/query's image path, plus the by-slug reads `get_tags`/`get_links`/`get_backlinks`/`get_timeline` (and `get_page`'s tag fetch, which resolves against the concrete page's own `source_id`). `linkReadScopeOpts(ctx)` is the link-read sibling for `get_links`/`get_backlinks`: a link row references three pages (from/to/origin), and the engine's federated (`sourceIds[]`) branch scopes ALL THREE while its scalar (`sourceId`) branch scopes only the near endpoint (by design — trusted internal callers like `reconcileLinks` and back-link validators call the engine with a scalar scope and need the cross-source view). For an UNTRUSTED remote caller (`ctx.remote !== false`) carrying only a scalar scope it promotes that scope to a single-element `sourceIds:[id]`, routing them through the all-endpoint branch so a far/origin slug from outside the grant isn't disclosed; a federated array passes through unchanged and trusted local CLI (`ctx.remote === false`) keeps the scalar cross-source view. `thinkSourceScopeOpts(ctx)` maps the same precedence ladder onto `runThink`'s public options (`allowedSources`/`sourceId`) so the `think` op's gather and trajectory stages inherit the caller's source grant. `put_page`'s inline disk write-through is the shared `writePageThrough` helper (`src/core/write-through.ts`), ATOMIC via temp-sibling + rename so a crash or concurrent `gbrain sync` can't read a half-written `.md`; same helper backs `gbrain brainstorm/lsd --save`. Link provenance surface (#1941): `add_link` (`gbrain link`/`link-add`) + `remove_link` (`gbrain unlink`/`link-rm`) expose `link_source`/`link_type`; `add_link` rejects the reconciliation-managed built-ins via `MANAGED_LINK_SOURCES` (`markdown`/`frontmatter`/`mentions`/`wikilink-resolved`) and defaults omitted provenance to `'manual'` (the engine's own default stays `'markdown'` for internal callers); `list_link_sources` (`gbrain link-sources`, read) lists provenances via `sourceScopeOpts`.

A deterministic registry recognizes known transcript formats. +2. An optional LLM fallback parses pages that every built-in pattern rejects. + +The second stage is disabled by default.

Override that tier when the +brain should use a different configured provider or model: + +```bash +gbrain config set models.tier.utility +``` + +Start with one known unmatched page and an explicit cost cap: + +```bash +gbrain extract-conversation-facts \ + --source-id \ + --slug \ + --max-cost-usd 1 +``` + +Do not add `--dry-run` to this canary. Dry runs deliberately stop before the +fallback boundary, so they cannot prove provider routing or model output. +Success emits the per-page fallback log described under +[Operator visibility](#operator-visibility). After the canary, remove `--slug` +to process the source normally. + +## When the fallback runs + +For each eligible conversation page, extraction: + +1. Reads the same body used by the deterministic parser, including a configured + raw transcript sidecar for meeting pages. +2. Calls `parseConversation(body, { page })`. +3. Uses the deterministic messages when any built-in pattern succeeds. +4. Calls the LLM fallback only when the parse phase is exactly `no_match`, the + message list is empty, the opt-in key is `true`, and this is not a dry run. +5. Splits accepted fallback messages into the normal extraction segments. + +The fallback never replaces, edits, or polishes a successful deterministic +parse. Adding a built-in pattern therefore removes model use for that format +without changing configuration. + +Dry runs remain local and cost-free. They report deterministic segmentation +only and never send unmatched content to a provider. + +## Data sent to the model + +The full unmatched body is processed in overlapping windows of at most 100 +non-empty lines, with up to 20 lines of preceding context. Blank lines are +omitted. Every model request receives: + +- an instruction to treat the transcript as untrusted data; +- an authoritative page date when one can be derived; +- the sampled transcript inside an explicit chat-log envelope. + +The system prompt tells the model not to follow commands or instructions found +inside transcript content. It asks for message extraction only. + +Each window is cached independently. Overlap results with the same normalized +speaker and timestamp are deduplicated; when one body contains the other, the +longer body wins. This preserves common multi-line messages that straddle a +window boundary. If any later window has an ordinary provider or parse failure, +the fallback returns no page result and extraction does not advance the +checkpoint. Successful earlier windows stay cached for the retry. + +Fallback calls allow up to 8,000 output tokens. Any non-terminal model stop, +including length truncation, refusal, content filtering, tool use, or an +unrecognized provider stop, is rejected before parsing and caching. A +syntactically valid partial JSON array therefore cannot advance a checkpoint. + +The utility model is resolved once per source run through the normal model +configuration chain. The default fallback is the utility-tier Anthropic model. + +## Date and timestamp behavior + +The fallback uses the deterministic parser's date precedence: + +1. an explicit caller date; +2. `frontmatter.date`; +3. the page effective date; +4. `1970-01-01` when no date is known. + +A real page date is included in both the prompt and the content-hash cache key. +Two pages with identical time-only transcript text but different dates cannot +share a cached parse. + +Returned timestamps must be strict RFC3339 date-times with seconds and an +explicit `Z` or numeric timezone offset. Calendar fields are validated before +parsing. Accepted timestamps are normalized to whole-second UTC form: + +```text +YYYY-MM-DDTHH:MM:SSZ +``` + +Date-only values, timezone-less values, impossible calendar dates, timestamps +more than 24 hours in the future, blank speakers, and blank message bodies are +discarded. Valid messages are stable-sorted by timestamp before segmentation. +Canonical chronological UTC output keeps segment filtering and durable +checkpoint comparisons stable and prevents future checkpoint poisoning. + +If no page date is known, the prompt retains the historical epoch fallback. +Full timestamps present in the transcript can still be extracted normally. + +## Non-chat and failure behavior + +The model is instructed to return an empty JSON array for non-chat content. +An empty response, malformed JSON, unavailable provider, or transport failure +leaves the page with no messages. Extraction skips that page and continues. + +The fallback is fail-open with respect to parser availability. It does not turn +a model outage into a deterministic-parser outage. + +Cancellation and `BudgetExhausted` are control-flow signals, not provider +failures. The extraction caller explicitly propagates them through the +fail-open boundary so aborts stay prompt and hard cost caps remain effective. +An `AbortError` from a provider timeout still fails open while the caller's own +abort signal remains live. + +The gateway can discover an underestimated budget overage only after the final +provider result. Extraction checks tracker spend against its cap after the run, +so an overage remains visible even when there is no next model reservation. + +## Cache and repeat runs + +Successful fallback results use the shared conversation-parser cache: + +- an in-process map for repeat calls during one process; +- the `conversation_parser_llm_cache` table for repeat calls across processes. + +Each chunk's cache key includes the call shape, resolved model, page date +metadata, and chunk content hash. A cached response is still validated before +it originally enters the cache. + +Once fallback messages produce extractable segments, the ordinary per-page +checkpoint advances to the newest segment timestamp. A later run can read the +cached parse, apply the checkpoint watermark, and skip already completed +segments without another provider call. + +## Operator visibility + +`ExtractConversationFactsResult.pages_llm_fallback` counts pages for which the +fallback returned at least one valid message. The command also logs: + +```text +[extract-conversation-facts] LLM fallback parsed N message(s) for +``` + +The multi-source CLI summary reports the total number of fallback-parsed pages. +A zero count means either the fallback was disabled, deterministic patterns +handled every page, or fallback attempts returned no valid messages. + +## Maintainer contracts + +Keep these boundaries intact when changing the fallback: + +- Default off. Page text must not reach the fallback without the exact opt-in. +- Never call the provider during `--dry-run`. +- Deterministic first. Invoke it only for phase `no_match`. +- One model resolution per source run, not per page. +- Use `deriveDateContext({ page })` so regex and LLM timestamps share metadata. +- Put date metadata in the hashed request content to prevent cross-date cache + collisions. +- Process every non-empty line in bounded cached overlapping windows. Preserve + common cross-boundary continuations through overlap and deterministic + deduplication. Never checkpoint a partial page after a later window fails or + returns a non-terminal stop reason. +- Validate and canonicalize all model-produced fields before segmentation. +- Stable-sort accepted messages before segmenting or checkpointing them. +- Keep the exact config key in `KNOWN_CONFIG_KEYS`. Do not register the whole + `conversation_parser.*` namespace while other scaffolded keys remain unwired. +- Preserve `[]` and `null` as skip-page outcomes. +- Propagate cancellation and budget-stop errors selected by the extraction + caller; fail open only for ordinary provider and parse failures. +- Never persist inferred regexes or promote model guesses into the built-in + registry. + +## Test coverage + +The focused tests cover: + +- default-off behavior with zero fallback calls; +- enabled dry-run behavior with zero provider calls; +- exact config-key registration; +- a successful production-path fallback; +- page-date prompt and cache-key separation; +- durable checkpoint advancement and cache reuse; +- complete processing beyond the first 100 non-empty lines; +- cross-boundary continuation preservation and overlap deduplication; +- rejection of truncated, refused, and content-filtered model results; +- all-or-nothing page results when a later chunk fails; +- non-chat empty arrays and malformed output; +- strict timestamp normalization, ordering, and invalid-item filtering; +- provider-unavailable and transport-failure behavior; +- provider-timeout versus caller-cancellation behavior; +- thrown and post-record budget-stop reporting. + +Run the focused surface with: + +```bash +bun test test/conversation-parser/llm-base.test.ts \ + test/conversation-parser/llm-fallback.test.ts \ + test/extract-conversation-facts.test.ts \ + test/config-set.test.ts +``` diff --git a/package.json b/package.json index 80d1a5e78..45380ac15 100644 --- a/package.json +++ b/package.json @@ -144,7 +144,7 @@ "bun": ">=1.3.10" }, "license": "MIT", - "version": "0.42.65.0", + "version": "0.42.66.0", "overrides": { "@hono/node-server": "^2.0.5", "fast-uri": "^3.1.4", diff --git a/src/commands/extract-conversation-facts.ts b/src/commands/extract-conversation-facts.ts index 0d6625604..6c0e74e2f 100644 --- a/src/commands/extract-conversation-facts.ts +++ b/src/commands/extract-conversation-facts.ts @@ -253,6 +253,11 @@ export interface ExtractConversationFactsResult { pages_skipped: number; pages_skipped_too_large: number; pages_skipped_disappeared: number; + /** + * Pages whose built-in parse returned `no_match` and whose messages were + * recovered by the explicitly enabled LLM fallback. + */ + pages_llm_fallback: number; /** * v0.41.15.0 (D6): pages we attempted to claim but skipped because * another worker / parallel process held the advisory lock.
