fix(migrate): transition all 3 dim-pinned columns + reconcile boundary-page signatures (#3390 review blockers)

BLOCKER 1 — runSchemaTransition only moved content_chunks.embedding.
query_cache.embedding and facts.embedding are separate dim-pinned columns
created at brain-birth width that NO migration ever ALTERs, so a dimension
change left them narrow:
  - query_cache: store() AND lookup() both fail on the width mismatch and both
    swallow the error by design (the cache must never break search), i.e. a
    PERMANENT, SILENT 0% hit rate on a system whose cost model credits cache
    hits with ~50% savings.
  - facts: every per-fact embed write fails, and the doctor check that would
    warn is skipped on PGLite — the DEFAULT engine, so the default-engine user
    got nothing.
runSchemaTransition now rebuilds all three in the same transaction,
preserving each column's declared type (vector vs halfvec, probed from
information_schema) and recreating its HNSW index with the matching opclass
under the hnswIndexExpected ceiling. Image/multimodal columns stay untouched
(separate models, independent dims). Fixes it for ze-switch too — one shared
path, all callers.

BLOCKER 2 — a page whose chunks straddle a listStaleChunks batch boundary was
never signature-stamped (the embed loop stamps only when
stale.length === existing.length, and the keyset LIMIT has no page alignment).
On any corpus >1 batch the boundary page was embedded correctly yet counted
stale, so the command printed "Migration incomplete" + exit 1 on a
fully-migrated brain AND the re-run re-invalidated and re-paid for those pages
— breaking the "already-migrated chunks are never re-embedded" contract.
Added reconcilePageSignatures(): one UPDATE after the drain stamping every
page with zero NULL-embedding chunks (sound because apply() invalidated
everything not already in the target space; pages with a remaining NULL chunk
stay unstamped so real embed failures still surface). Wired into both the CLI
and the op. New --batch-size passthrough makes the boundary reachable in a
test and matches the knob  already has.

ORDERING — invalidation now runs BEFORE the config writes. On a same-dim
provider swap there is no schema transition to null the vectors, so a crash in
the old window left new-space query embeddings scored against old-space
document vectors: silently WRONG results. Invalidate-first makes that window
merely stale (empty/degraded), never wrong.

OP SAFETY PARITY — the migrate_embeddings handler now runs the same live
provider probe (so yes:true can't drop the column against a bad key) and takes
the same singleFlight embed-backfill lock (so it can't race a queued backfill
on the NULL→non-NULL upsert, the TODOS:2299 class) as the CLI path. Probe
extracted to a shared probeTargetProvider().

ALSO:
- persistEmbeddingFileConfig REFUSES when loadConfig() is null instead of
  warn-and-proceed (without a file plane the switch dies with the process and
  the next run re-embeds into the old space).
- The #3391 left-behind warning is no longer gated on invalidated>0 — the bug
  report's own shape (every page NULL-signature) invalidates nothing, so that
  brain got no warning and no work. The probe computes the count directly and
  stays quiet at 0.
- migrate.reembed documented in docs/progress-events.md.
- The destructiveness warning now says plainly that vectors are DELETED and
  that reverting costs a second full re-embed.

Tests (both blockers have negative controls proving they catch the bug):
- 3 new unit cases: all three column widths post-transition + a real INSERT at
  the new width into query_cache and facts + reconcile semantics.
- test/migrate-embeddings-boundary.serial.test.ts: 3 pages x 2 chunks at
  --batch-size 3 → exit 0, every page stamped, ZERO work on the second run.
  With the reconcile disabled it fails exactly as reported (exit 1, 2 chunks
  stale, second run re-embeds 2).
- Real-Postgres e2e extended to assert all three widths + accepting inserts.

Merged origin/master. VERSION/package.json/CHANGELOG deliberately untouched
and consistent at 0.42.66.1 — the version bump is deferred to /ship.

 All notable changes to GBrain will be documented in this file.
 
+## [0.42.66.1] - 2026-07-27
+
+### Fixed
+
+- `gbrain doctor` now treats embedding columns wider than pgvector's HNSW limit as healthy exact-scan configurations instead of prescribing an index PostgreSQL cannot build.
+- Local CI now passes an empty Docker mount list correctly and compiles the embedded-WASM smoke binary from container-local storage on Docker Desktop.
+
+## [0.42.66.0] - 2026-07-24
+
+**54 verified fixes from the community backlog: background enrichment stops wasting money on dead pages, autopilot stops killing its own healthy runs, and search respects your settings.**
+
+This release is the second big sweep through the open pull-request backlog, with every change reviewed and tested individually before merging. The theme is trust in the background machinery. The overnight "dream" cycle now remembers which pages produced nothing and stops re-reading them every night, meters its small-model calls against your spend caps, and keeps claim proposals from silently overwriting each other. Long consolidation runs get a 30-minute deadline instead of being killed at 10 minutes mid-work. A wedged server boot now releases its database lock instead of blocking every later command.
+
+Search behaves the way you configured it: the recency-decay setting now actually applies to hybrid search, a local `list_pages` call returns as many rows as you asked for, and when a listing is cut short it says so instead of looking complete. Slack conversation exports parse cleanly, with an optional AI fallback for formats the parser does not know.
+
+New provider recipes: DashScope reranking, OpenRouter reranking, and a claude-cli recipe for dispatching subagents through the gateway.
+
+## To take advantage of v0.42.66.0
+
+`gbrain upgrade` should do this automatically. One schema migration ships in this release (v125, take-proposal idempotency); it is idempotent and needs no manual action.
+
+1. **Upgrade and verify:**
+   ```bash
+   gbrain upgrade
+   gbrain doctor
+   gbrain stats
+   ```
+2. **If `gbrain doctor` warns about a partial migration**, run the orchestrator manually:
+   ```bash
+   gbrain apply-migrations --yes
+   ```
+3. **If any step fails,** please file an issue at https://github.com/garrytan/gbrain/issues with the output of `gbrain doctor` and `~/.gbrain/upgrade-errors.jsonl` if it exists.
+
+### Itemized changes
+
+#### Dream cycle, takes, and spend control
+
+- Pages whose extraction yields zero claims are memoized, so the cycle stops re-spending on them every night. (#2514, #3319, contributed by @ivandebot)
+- Zero-yield pages are tombstoned so `extract_atoms` stops rediscovering them. (#2144, #3304, contributed by @ChenyqThu)
+- `extract_atoms` Haiku calls are metered against the cost gate. (#2371, #3329, contributed by @TheRealMrSystem)
+- `extract_atoms` stamps concepts so `synthesize_concepts` has material to work with. (#2123, #3308, contributed by @ChenyqThu)
+- `extract_facts` requires a live backing page, not just a non-NULL entity slug. (#2497, #3321, contributed by @javieraldape)
+- Multi-claim pages keep every proposal instead of only the first (migration v125 makes the idempotency key per claim). (#3297, contributed by @rp-agent-bot)
+- Superseding a take now queries the active row first. (#3275, contributed by @arisgysel-design)
+- Takes keyword search matches words inside long claims via `word_similarity`. (#3267)
+- Dream-generated orphan pages stay scoped to their source. (#2368, #3344, contributed by @snvtac)
+- Drift detection is wired into the dream cycle, report-only for now. (#2653, #3317)
+
+#### Autopilot, jobs, and serve
+
+- Full consolidation cycles get a 30-minute timeout floor; lighter dispatches keep the interval-derived budget. (#2852, #3338, contributed by @sanchalr)
+- The cron wrapper exports `~/.bun/bin` onto PATH so autopilot survives minimal environments. (#2013, #3305, contributed by @klampatech)
+- Dead or cancelled jobs no longer block idempotent re-submission. (#2253, #3306, contributed by @rafaelreis-r)
+- Contextual reindex jobs get a default timeout. (#2611, #3323, contributed by @spiky02plateau)
+- Onboarding stops repeating the same auto-remediation within a single run. (#2854, #3342, contributed by @sanchalr)
+- A wedged `gbrain serve` boot hits a readiness deadline and releases the PGLite lock. (#3335)
+
+#### Search, retrieval, and health
+
+- The recency-decay config is honored on the hybrid search path. (#2386, #3312, contributed by @rwbaker)
+- `list_pages` honors explicit limits for local callers, warns on remote clamping, and threads `offset`. (#2591, #3322, contributed by @deacon-botdoctor)
+- Truncated `list_pages` results say so instead of silently capping. (#2865, #3341, contributed by @paul-0320)
+- Negative metrics no longer invert trajectory regression signals. (#2621, #3324, contributed by @morluto)
+- Per-chunk synopsis generation in contextual retrieval is concurrency-bounded. (#2628, #3326, contributed by @spiky02plateau)
+- Graph health metrics count `entity` pages. (#2639, #3330, contributed by @tylr-r)
+
+#### Ingestion, extraction, and links
+
+- Conversation parsing gains an opt-in LLM fallback for unknown formats. (#2247, #3371, contributed by @danwiggins)
+- Normalized Slack markdown parses into conversations. (#3289, #3372, contributed by @danwiggins)
+- Conversation backfill outcomes are durable, so completed pages skip on the next run. (#3293, #3373, contributed by @danwiggins)
+- Reference-style wikilinks are recognized during extraction. (#2071, #3303, contributed by @mzkarami)
+- `[[wikilink]]` frontmatter values resolve via global basename lookup. (#2406, #3313, contributed by @spiky02plateau)
+- Incremental push syncs extract links. (#2850, #3337, contributed by @patentsong)
+- `<think>` reasoning tags in extractor output are handled. (#2559, #3318, contributed by @qaz8545355)
+- Tiktoken special tokens no longer crash code-chunker token estimates. (#2453, #3315, contributed by @Jiglet)
+- Source config stops re-wrapping into a growing JSON string scalar. (#2829, #3334, contributed by @1alessio)
+
+#### Providers and recipes
+
+- DashScope reranking recipe (DashScope serves a plural `/reranks` endpoint under its compatible API). (#2644, #3328, contributed by @YiconZiwei)
+- OpenRouter reranking touchpoint. (#2164, #3302, contributed by @Hippityy)
+- claude-cli recipe for native gateway-based subagent dispatch. (#2277, #3310, contributed by @brettdavies)
+- Prefixed model IDs work on the openai-compatible embedding-dimensions path. (#2325, #3309, contributed by @noetherly)
+- Embeddings stamp the gateway-resolved model in `content_chunks.model`, not the compiled default. (#2846, #3343, contributed by @SailorJoe6)
+- Bun-on-Windows write-through EEXIST fixed, non-Anthropic `--max-cost` pricing works, dream pages excluded from enrich. (#2407, #3316, contributed by @nguyenchiviet)
+- Supabase signed URLs prepend `/storage/v1`. (#2565, #3320, contributed by @danwiggins)
+
+#### Sources, auth, and multi-brain
+
+- Federated-source pages are visible to `get_page`, `list_pages`, `resolve_slugs`, and no-grant MCP callers. (#3242, #3301)
+- Admin-gated rescope surface for DCR clients stuck on a default scope. (#3299)
+- `whoami` exposes OAuth source grants. (#3279, #3332, contributed by @boundless-forest)
+- Thin-client `--source` maps onto `source_id` for remote-routed operations. (#3086)
+
+#### CLI, doctor, and init
+
+- `gbrain doctor` stops claiming "Brain is at target" when the target is unreachable. (#2151, #3339, contributed by @brettdavies)
+- Doctor gains a raw-source persistence guarantee for synthesized pages, warn-only for now. (#3300)
+- Doctor timeline labels disambiguate entity coverage from the brain-score component. (#2298, #3073, contributed by @TurgutKural)
+- Unknown `gbrain init` flags are rejected before migrations run. (#2201, #3307, contributed by @caioribeiroclw-pixel)
+- The init soul-audit hint points at the conversational skill, not a nonexistent CLI verb. (#2486, #3314, contributed by @SeanGearin)
+- `--force` retry escapes completed migration-ledger entries. (#2616, #3325, contributed by @spiky02plateau)
+- PGLite data-dir lock contention gets a clear error message. (#2658, #3336, contributed by @zaycruz)
+- Frontmatter validation derives slugs from the brain root, not the absolute path. (#2340, #3311, contributed by @alessioalionco)
+
+#### For contributors
+
+- Docker network isolation guidance for co-located self-hosted Postgres. (#3270, #3331)
+- `CLAUDE.local.md` / `AGENTS.local.md` are gitignored. (#3290, contributed by @igbymyboy)
+- The hybrid-reranker integration test isolates `GBRAIN_HOME`. (#1527, #3327, contributed by @Willisbest)
+- Test-shard scripts capture the real exit code before watchdog teardown in the no-timeout fallback. (#2864, #3340, contributed by @paul-0320)

+If you use gbrain day to day, this release makes the boring parts trustworthy. Importing and syncing notes is safer: a failed pull no longer pretends everything is up to date, imported pages are read back after writing to confirm they landed, and a page with real content can no longer be silently overwritten by an empty one. Search answers get better inputs: the think command now picks excerpts that actually match your question, and results respect your federated source settings. Background enrichment (the "dream" cycle) wastes less money and retries properly when an AI provider is down. Spending caps now fail closed, so a billing hiccup can never turn into an uncapped spend. And `gbrain doctor` is quieter, with several false alarms removed and real problems (like an embedding backlog with no worker running) now flagged.
+
+More AI providers work out of the box, including OpenRouter prompt caching, MiniMax and Zhipu GLM recipes, Ollama Matryoshka embedding dimensions, and llama-server batch limits.
+
+## To take advantage of v0.42.65.0
+
+`gbrain upgrade` should do this automatically. No new schema migrations ship in this release.
+
+1. **Upgrade and verify:**
+   ```bash
+   gbrain upgrade
+   gbrain doctor
+   gbrain stats
+   ```
+2. **If `gbrain doctor` reports new findings after upgrading,** that is the quieter, more accurate check set working as intended. Each finding names its fix.
+3. **If any step fails,** please file an issue at https://github.com/garrytan/gbrain/issues with the output of `gbrain doctor` and `~/.gbrain/upgrade-errors.jsonl` if it exists.
+
+### Itemized changes
+
+#### Security
+
+- MCP source scoping for remote callers got a hardening pass, so agent-facing connections stay confined to the sources they were granted. (#2881, contributed by @spinsirr)
+- Paid MCP spend accounting is now atomic and fails closed, and resolver spend is recorded before a cap error is raised, so caps cannot be raced past or undercounted. (#3203, #3204, contributed by @caterpillarC15)
+- The OAuth token endpoint rate limit on the HTTP server is now configurable via env for deployments behind shared IPs. (#3114, contributed by @time-attack)
+- `WWW-Authenticate` responses now carry `resource_metadata` per the MCP spec and RFC 9728, so conforming clients can discover the auth server. (#1410, contributed by @rayers)
+
+#### Search, retrieval, and think
+
+- `think` selects query-relevant excerpts instead of generic ones. (#3197, contributed by @Y0lan)
+- Unqualified local CLI `search`/`query` now honors `sources.config.federated` read visibility. (#2561, #3141, contributed by @time-attack)
+- Email citation metadata is projected into search results. (#2873, contributed by @amtagrwl)
+- The `think` Gaps section renders once instead of twice. (#1662, contributed by @howwohmm)
+- Fuzzy entity lookup threads the caller's source scope and skips soft-deleted entities. (#1508, contributed by @tim404x)
+- `code-def` surfaces method, constructor, field, and struct definitions, not just top-level symbols. (#1628, contributed by @rayers)
+- Briefing pages are excluded from their own Brain Pulse salience. (#1202, contributed by @rwbaker)
+- Reranker calls with missing auth are classified as configuration errors before falling back. (#2059, #3139, contributed by @time-attack)
+
+#### Import, sync, and ingestion
+
+- A failed git pull with zero imports reports `partial (pull_failed)` instead of `up_to_date`. (#3068, #3253, contributed by @Masashi-Ono0611)
+- Imports run a post-write read-back verification with a durable ingest-log record. (#2869, contributed by @Andredsouza1984)
+- `put` refuses to overwrite a non-empty page with empty content. (#2708, contributed by @symmetric-matthew)
+- `putPage` restores soft-deleted rows instead of colliding with them. (#2779, contributed by @RerankerGuo)
+- Mixed-case slugs are normalized before chunk upsert, ending duplicate-chunk churn. (#430, #3143, contributed by @time-attack)
+- Imports fall back to the body H1 for the title when frontmatter lacks `title:`. (#2446, #3072, contributed by @time-attack)
+- YAML comments inside the frontmatter fence are no longer treated as markdown headings. (#3225, #3247, contributed by @Masashi-Ono0611)
+- Write-through guards case-insensitive filesystem collisions before the atomic write. (#2831, #3119, contributed by @time-attack)
+- Path-qualified wikilinks outside the known directory pattern resolve on the DB/put_page path. (#2866, contributed by @paul-0320)
+- CJK slugs are supported in the slug registry and dream-cycle summary slugs. (#782, #738, #3083, contributed by @time-attack)
+- Three ingest/sync/serve singleton fixes: page-type round-trip, deleted-slug embed noise, and a stateless width guard. (#3140, contributed by @time-attack)
+- Sync honors the `embedding_disabled` sentinel as an implicit `--no-embed`. (#2879, contributed by @gawievanblerk)
+- Verified sync head sentinels are cleared correctly. (#2734, contributed by @symmetric-matthew)
+- Resumed syncs report the pinned commit they actually landed on. (#3202, contributed by @caterpillarC15)
+- The expected `discover_git_root` probe failure stays off stderr. (#3232, contributed by @Masashi-Ono0611)
+- `extract --stale` runs the real resolver so basename resolution reaches stale pages, and clears pre-version-bump pages. (#2576, #2717, contributed by @paul-0320; #1791, contributed by @Nazim22)
+- Oversized code chunks are capped so they stay embeddable, and code-chunk metadata survives re-embeds. (#1675, contributed by @lubosxyz; #769, #1232, contributed by @rayers)
+
+#### Background cycle, dream, and facts
+
+- Path-derived dream sources are stamped, and the engine closes cleanly on autopilot shutdown. (#3178, contributed by @time-attack)
+- All-provider-failed atom drains propagate so durable jobs retry instead of silently dropping work. (#3218, #3248, contributed by @Masashi-Ono0611)
+- Atom extraction raises `maxTokens` and case-normalizes `atom_type` for Gemini models. (#3211, contributed by @alexey-metaengage)
+- The conversation extractor gates anonymous-speaker self-attribution instead of guessing. (#3228, contributed by @asenkovskiy)
+- Incremental dream extraction stamps its watermark so re-runs stop reprocessing. (#2636, #3115, contributed by @time-attack)
+- `dream --dry-run --json` keeps stdout clean of embed summaries. (#394, #3109, contributed by @time-attack)
+- Synthesized dream pages require a self-contained opening summary. (#2770, contributed by @Masashi-Ono0611)
+- PGLite inline synth subagent drains complete, and `lint` gains `--exclude`. (#2699, #2649, #3162, contributed by @time-attack)
+- Live context reads the documented "P1 Today" heading form with plain checkbox tasks, matching the daily-task-manager skill's output format. (#2186, #3124, contributed by @time-attack)
+- Queued AI jobs refresh gateway config at execution time instead of using a stale snapshot. (#2125, contributed by @maxpetrusenkoagent)
+- `brainstorm`/`propose_takes` honor configured models: cost preview uses the configured model, the judge reads its config key, provider probes are skipped when unneeded, and page projection is narrowed. (#3120, contributed by @time-attack)
+- Backlog hardening wave: x-to-brain health check, propose_takes deadlines, capture title truncation, extract_atoms backlog handling, and pooler direct-URL routing. (#3165, contributed by @time-attack)
+- `skillopt` emits `proposed.md` in no-mutate mode. (#2635, #3182, contributed by @time-attack)
+- Nightly quality probe enable path and conversation-parser probe are wired up. (#2629, #2630, #3094, contributed by @time-attack)
+
+#### Doctor, health, and maintenance
+
+- New safe maintenance automation with a shared orphan-exclusion policy, so routine cleanup runs without risking linked content. (#3015, #3023, contributed by @time-attack)
+- `orphan_ratio` excludes the chronicle volume under `life/events/`. (#2264, #3214, contributed by @asenkovskiy)
+- `brain_score` orphan/timeline components use the orphans-audit linkable scope. (#3155, contributed by @time-attack)
+- Entity timeline coverage is measured separately from whole-brain density. (#2761, contributed by @TurgutKural)
+- Doctor flags embed backfills queued with no worker running. (#2696, contributed by @javieraldape)
+- Two doctor false-positive/timeout fixes: the drift walk skips `node_modules`, and the bare-tweet check skips inline code and cited lines. (#1772, contributed by @sonlndv)
+- A dead `llm_fallback_enabled` recommendation is dropped from conversation format coverage. (#1903, contributed by @ElliotDrel)
+- Skill triggers with CRLF line endings parse on Windows. (#1149, contributed by @samporter-31)
+- Onboard check names are registered in doctor categories, ending unknown-check warnings, and onboard-check remediations survive the `--apply --auto` path. (#3075, #3097, contributed by @time-attack)
+- Dead slug prefixes are counted by slug. (#2697, contributed by @RerankerGuo)
+- The backlinks worker defaults to check, not fix, and `check-backlinks` honors its positional directory argument. (#1853, contributed by @choomz; #3076, contributed by @time-attack)
+- Calibration resolves the owner holder via config, defaulting to `self`. (#3077, contributed by @time-attack)
+- Memory throttling on Linux reads `/proc/meminfo` MemAvailable. (#556, contributed by @chengzehsu)
+
+#### AI providers and gateway
+
+- OpenRouter gets family-scoped prompt caching, and query expansion works on chat-capable openai-compat recipes. (#3152, contributed by @time-attack)
+- MiniMax recipe: embedding wire-shape compat fetch plus a chat touchpoint. (#1977, #3089, contributed by @time-attack)
+- The Zhipu recipe gains a chat touchpoint so GLM subagents work. (#1157, #3084, contributed by @time-attack)
+- Tier-configured models reach the recipe allowlist, Anthropic model lists are refreshed, tier resolutions are registered, and probe labels are honest. (#2800, contributed by @p3ob7o)
+- Provider base URL config merges from the DB. (#1676, contributed by @TheLordArgus)
+- The gateway falls back to the pooler when the derived direct host is unreachable. (#1641, #3088, contributed by @time-attack)
+- Config-plane `voyage_api_key` folds into `VOYAGE_API_KEY` like the other hosted keys. (#3236, contributed by @Masashi-Ono0611)
+- The `zeroentropyai:zerank-2` reranker has a pricing entry so the budget tracker can meter it. (#3223, #3233, contributed by @Masashi-Ono0611)
+- llama-server embedding batches are capped at its 32-input request limit. (#1281, contributed by @mmekkaoui)
+- Matryoshka dimensions thread through for Qwen3-Embedding on Ollama. (#1072, contributed by @mgandal)
+- `init` seeds AI options from env on cold install, and `whoami` reports the stdio transport. (#3091, contributed by @time-attack)
+- The `models` dispatch subcommand reads its first argument correctly. (#1428, contributed by @BenjaminDSmithy)
+- Synopsis generation tail-truncates document text for small-model chat handlers. (#1427, contributed by @BenjaminDSmithy)
+- The contradiction judge token cap is raised for thinking models. (#3210, contributed by @alexey-metaengage)
+
+#### Schema, migrations, and storage engines
+
+- Engine migration counts and surfaces per-page copy failures instead of silently advancing. (#3241, contributed by @Masashi-Ono0611)
+- Invalid `CONCURRENTLY`-build index remnants are dropped without a DO block. (#3191, contributed by @Masashi-Ono0611)
+- Unsupported large-dimension HNSW indexes are skipped instead of failing schema setup. (#1734, #3080, contributed by @time-attack)
+- The v0.32.2 migration dirty-check scopes to targeted sources and surfaces failed phase detail. (#3093, contributed by @time-attack)
+- Schema packs merge the full `extends` chain and `borrow_from` into the resolved manifest. (#1749, #3181, contributed by @time-attack)
+- The schema-pack stats catch-all is narrowed so masked errors surface instead of fake zero-page counts. (#2466, #3133, contributed by @time-attack)
+- Bundled schema-pack inspection reports the pack actually shipped in the binary, and minion subagent auth resolves through config. (#3110, contributed by @time-attack)
+- PGLite `putPage` guards against zero-row RETURNING. (#1649, contributed by @alexhawkins)
+
+#### MCP server and CLI surface
+
+- `list_pages` rows include `source_id`. (#3209, contributed by @alexey-metaengage)
+- Running CLI commands while `gbrain serve` (MCP) holds the brain now notifies about the conflict instead of failing confusingly. (#3243, contributed by @fdefitte)
+- The OpenClaw plugin manifest entry is declared so the plugin loads. (#2551, #3185, contributed by @time-attack)
+
+#### For contributors
+
+- CI scanner roots are normalized on macOS. (#3198, contributed by @caterpillarC15)
+- CI shard timeout raised to 22 minutes plus a delta-assert reporter leak test. (#3231, contributed by @time-attack)
+- E2E suite hardening: flaky tests, no-op assertions, and cross-test coupling removed. (#1704, contributed by @auroracapital)
+- `mechanical.test.ts` isolates `$HOME` so the E2E suite stops clobbering user config. (#434, contributed by @lloydarmbrust)
+- The lint code-fence-wrap detector and fixer regex now agree. (#1597, contributed by @chungty)
+- README project links for OpenClaw and Hermes are corrected. (#1961, #3179, contributed by @time-attack)
+- A completed TODOS entry is dropped. (#3229, contributed by @Masashi-Ono0611)

+# Conversation parser patterns
+
+The conversation parser turns exported chat and meeting transcripts into a
+common message stream without requiring an LLM call for known formats. This
+document describes the built-in pattern contract and the checks required when
+adding or changing a format.
+
+## Data flow
+
+`parseConversation` uses this sequence:
+
+1. Resolve the page date and timezone context.
+2. Score every enabled built-in and user pattern against the first ten
+   non-blank lines.
+3. Re-score the full body when the head score is inconclusive, or when a broad
+   pattern explicitly requires full-body scoring.
+4. Reject the winner when its acceptance score is below the false-positive
+   floor.
+5. Apply the winning pattern to every line and attach continuation lines to the
+   preceding message.
+6. Optionally run LLM polish or fallback when those features are enabled.
+
+Pattern order is only a tie-breaker. A new regex must be structurally distinct
+from neighboring formats; moving it earlier in the registry is not a valid
+non-shadowing strategy.
+
+## Built-in pattern contract
+
+Every `PatternEntry` in `builtins.ts` declares:
+
+- A stable, kebab-case `id`.
+- A hand-vetted line regex and explicit capture-group indexes.
+- Where the date comes from and how the time is represented.
+- A timezone policy.
+- Whether the format supports multi-line message bodies.
+- Positive and negative samples that run during module initialization.
+- A documentation pointer describing the source format.
+
+The registry refuses to load when a positive sample stops matching, a negative
+sample starts matching, or a capture map becomes invalid. This catches local
+regex mistakes before extraction can silently produce empty conversations.
+
+### Date and timezone rules
+
+Formats with an inline date should capture it from each message. Time-only
+formats use an explicit caller fallback first, then the page frontmatter date,
+then the page effective date. If none is available, the parser uses
+`1970-01-01` so the missing date remains visible instead of inventing a current
+date.
+
+Time-only formats normally use `utc_assumed_with_warn`. The parser constructs a
+UTC timestamp and returns a timezone warning when the page does not provide a
+timezone. A new pattern should not imply local-time precision that the source
+format does not contain.
+
+### Multi-line messages
+
+An anchor regex identifies the first line of a message. Subsequent non-anchor
+lines are appended to that message until another anchor appears. Set
+`multi_line: true` when continuation content is part of the documented format,
+such as Markdown bullets, blockquotes, or an exported message body on the next
+line.
+
+Tests for a multi-line format should assert the complete message text, including
+newlines. A message-count assertion alone will not detect lost bullets or a
+continuation attached to the wrong speaker.
+
+### Scoring and false positives
+
+The score compares matched anchors with the pattern's relevant candidate lines.
+The first pass uses the head of the page for speed. Low-confidence pages are
+re-scored across the full body before the parser accepts a winner.
+
+Multi-line formats may opt into `score_continuations_as_body` when their anchor
+grammar is distinctive. Candidate-only scoring activates only after two anchors
+match, or when the first non-blank line is an anchor. This evidence threshold
+lets a single long message keep its continuation body without turning one stray
+anchor in a prose page into a conversation. Candidate anchor lines that fail the
+full regex still lower the score. Other patterns continue to use all non-blank
+lines in their density score.
+
+Use `score_full_body: true` for a broad grammar that also occurs in ordinary
+prose. For example, `**Label:** text` can be either a transcript line or a bold
+label in meeting notes. Narrow formats with a timestamp and a distinctive
+separator generally do not need this override.
+
+`quick_reject` is a performance hint, not an acceptance rule. It should cheaply
+exclude obviously unrelated lines while admitting every string accepted by the
+main regex.
+
+## Normalized Slack Markdown
+
+The `bold-time-dash` pattern parses message anchors shaped like:
+
+```text
+**Alice Example** 09:15 — first message
+- supporting detail
+**Bob Example** 09:18 — second message
+```
+
+Its grammar is:
+
+```text
+**speaker** H:MM <dash> text
+```
+
+where:
+
+- `H:MM` is a valid 24-hour time from `0:00` through `23:59`.
+- `<dash>` may be an em dash (`—`), en dash (`–`), or ASCII hyphen (`-`).
+- The date comes from the resolved page date context.
+- Continuation lines belong to the preceding message.
+- The captured clock value is emitted with `Z`. Timezone metadata suppresses
+  the missing-timezone warning but is not currently used for IANA conversion.
+
+The required time and dash distinguish it from all existing bold-speaker
+formats:
+
+- `**Speaker** (09:15): text` uses `bold-paren-time`.
+- `**Speaker** (9:15 AM): text` uses `bold-paren-time-12h`.
+- `**Speaker:** text` uses `bold-name-no-time`.
+- `**Speaker** (2026-04-09 9:15 AM): text` uses `imessage-slack`.
+
+Keeping these examples in both `test_negative` and parser regression tests makes
+the non-shadowing contract executable.
+
+## Adding a built-in format
+
+1. Collect multiple anonymized examples, including separator and timestamp
+   variants that occur in the same export family.
+2. Choose the narrowest grammar that represents the format. Constrain numeric
+   fields such as hours and minutes when possible.
+3. Add at least two positive module-load samples and negative samples for every
+   neighboring pattern that could plausibly overlap.
+4. Add parser tests that verify speakers, timestamps, text, continuation
+   handling, and non-shadowing behavior.
+5. Add a dedicated JSONL fixture and include the same cases in
+   `test/fixtures/conversation-formats/all.jsonl`.
+6. Run the focused parser tests and the fixture evaluator.
+7. Run the repository verification and full test suites before submission.
+8. Update `docs/architecture/KEY_FILES.md` when the registry count or supported
+   format inventory changes.
+
+Use generic fixture identities such as `Alice Example`, `Bob Example`, and
+`Summary Bot`. Never copy real transcript names or private content into source,
+tests, documentation, commits, or pull-request descriptions.

+# Embedding migration — moving a brain to another embedding provider
+
+`gbrain migrate embeddings` re-embeds an entire brain onto a different
+embedding provider/model, safely and resumably. It is the forward path off a
+sunsetting provider (for example ZeroEntropy's hosted API, which shuts down
+2026-09-04 and is the shipped default for brains that never picked a model) —
+but it is provider-agnostic: any configured `provider:model` works as a
+target.
+
+Also reachable as `gbrain retrieval-upgrade` (the name `doctor` and the
+README reference).
+
+## Quick start
+
+```bash
+# Preview the work + cost. Changes nothing.
+gbrain migrate embeddings --to openai:text-embedding-3-small --dry-run
+
+# Run it (interactive confirm shows chunk count + $ estimate first).
+gbrain migrate embeddings --to openai:text-embedding-3-small
+
+# Non-interactive (cron / scripts): --yes is required, else exit 2.
+gbrain migrate embeddings --to voyage:voyage-3-large --yes
+```
+
+`--dim <N>` overrides the target width; it defaults to the provider recipe's
+declared width and is required for recipes that don't declare one (litellm,
+llama-server, and other bring-your-own-model providers).
+
+## What it does, in order
+
+1. **Plan.** Counts every chunk not already in the target embedding space —
+   including chunks on pages with **no recorded embedding signature**
+   (pages embedded before the v108 provenance stamp). Prices the re-embed
+   from the pricing table; unknown providers print "estimate unavailable"
+   instead of a fabricated number.
+2. **Consent gate.** Prints the plan; requires an interactive `y` or `--yes`.
+   Non-TTY without `--yes` refuses with exit 2 (mirrors the `reindex-code`
+   gate in [spend-controls](../operations/spend-controls.md)). Unlike the pure
+   cost gates there, `spend.posture=tokenmax` does **not** bypass this one:
+   posture waives the spend *ceiling*, and this gate also guards a
+   destructive schema rebuild. Under `tokenmax` the dollar figure is marked
+   informational and the confirmation is still asked. `--yes` is the single
+   scripted bypass.
+3. **Live probe.** One tiny embed against the TARGET provider before any
+   mutation — validates the API key, model id, and dimension support in a
+   single call. A bad key fails here, with nothing changed.
+4. **Env-override gate.** Refuses when `GBRAIN_EMBEDDING_MODEL` /
+   `GBRAIN_EMBEDDING_DIMENSIONS` would silently defeat the switch at
+   runtime (the same guard `ze-switch` uses). `--ignore-env-override` for
+   people running deliberate experiments.
+5. **Apply.** When the target width differs from the actual column width,
+   runs the same atomic schema transition `ze-switch` uses, in one
+   transaction. It rebuilds **all three dim-pinned text-embedding-space
+   columns** — `content_chunks.embedding`, `query_cache.embedding`, and
+   `facts.embedding` — at the new width, preserving each column's type
+   (`vector` vs `halfvec`) and recreating its HNSW index. Missing any of the
+   three leaves it silently broken: a narrow `query_cache.embedding` makes
+   every cache write and read fail *by design* (the cache swallows errors so
+   it can never break search) for a permanent 0% hit rate, and a narrow
+   `facts.embedding` fails every per-fact embed write. The image/multimodal
+   columns ARE deliberately untouched — they use separate models whose
+   dimensions are independent of the text embedding model.
+   Writes `embedding_model` + `embedding_dimensions` to BOTH config planes
+   (file plane for the runtime gateway, DB plane for doctor), invalidates
+   every chunk still in the old space — **including NULL-signature pages** —
+   and purges the semantic query cache so stale cached results can't be
+   served across the swap.
+6. **Re-embed.** The standard embed pipeline (`embed --stale --catch-up`)
+   with per-source single-flight locks, rate-limit backoff, stderr progress,
+   and optional DB-contention pacing (`--pace[=mode]`).
+
+## What the rebuild deletes
+
+The dimension change **deletes every stored embedding vector** in the brain —
+they are in the old model's space and unusable. They are not recoverable:
+going back to the previous provider means paying for a second full re-embed.
+`content_chunks` vectors are rebuilt by the re-embed pass, the query cache
+refills on the next query, and fact embeddings are rewritten on their next
+write (or a `gbrain extract` pass).
+
+## Resume after a kill
+
+The NULL-embedding column is the checkpoint. If the run is killed (or some
+pages fail to embed), re-run the **same command**: chunks already embedded on
+the target are never re-embedded, the schema/config steps no-op, and the run
+continues where it stopped. An in-flight marker (`embedding_migration.state`
+in DB config) records the target; it is cleared only when the backlog drains
+to zero.
+
+A page whose chunks straddle two stale batches is embedded correctly but not
+stamped by the embed loop (which only stamps all-or-nothing per batch), so the
+migration runs one reconcile pass after the drain that stamps every
+fully-embedded page. Without it a large brain would report "incomplete" and the
+re-run would pay again for those pages. `--batch-size N` tunes the batch
+(default 2000).
+
+`--no-embed` applies schema + config + invalidation and stops, so you can run
+the (potentially long) re-embed later or in the background:
+
+```bash
+gbrain migrate embeddings --to openai:text-embedding-3-small --yes --no-embed
+gbrain embed --stale --catch-up --include-null-signature --background
+```
+
+## During the migration
+
+While the re-embed runs, semantic search returns degraded (lexical-arm-only)
+results for not-yet-re-embedded content. Pick a quiet window for large
+brains, or use `--pace` to keep the DB responsive.
+
+## Pages without an embedding signature (#3391)
+
+Pages embedded before provenance stamping have `embedding_signature IS NULL`
+and are grandfathered by the routine stale sweep (so an upgrade never
+surprise-re-embeds a whole corpus). After a provider swap that grandfather
+clause would silently leave those pages in the OLD embedding space — mixed
+vector spaces in one index, degrading retrieval with nothing in the logs.
+
+- `gbrain migrate embeddings` always includes them.
+- Plain `gbrain embed --stale` warns when a model swap leaves NULL-signature
+  pages behind, and `gbrain embed --stale --include-null-signature` re-embeds
+  them.
+
+## Reranker
+
+Migrating embeddings does not touch the reranker. If
+`search.reranker.model` points at the outgoing provider, the plan prints a
+warning; disable it (`gbrain config set search.reranker.enabled false`) or
+point it at another provider.
+
+## Self-hosting instead of migrating
+
+If the outgoing model's weights are available (zembed-1's are Apache-2.0),
+serving them locally via `llama-server` / `ollama` / a LiteLLM proxy
+preserves your existing vectors — no re-embed at all. Point
+`embedding_model` at the local recipe and keep the same dimensions. The
+migration command is for when you'd rather move to a hosted provider.

+NOT guard raw Postgres. If the brain's Postgres runs as a container on the same
+Docker host as other workloads (agent runtimes, n8n, staging fixtures), any
+container sharing Docker's default `bridge` network can open a direct DB

+# Conversation backfill durable outcomes
+
+`gbrain extract-conversation-facts` stores page-level outcomes in `facts` so
+bulk runs, autopilot, and `gbrain doctor` can distinguish finished work from
+retryable work without adding another state table.
+
+This is completion authority, not ordinary extracted knowledge. The authority
+is deliberately narrow: a marker is valid only for the exact page or transcript
+snapshot that was parsed, and only after every required operation succeeded.
+
+## Outcome protocol
+
+The current protocol is v2. Its source names are versioned so rows written by
+older best-effort implementations cannot suppress a corrective replay.
+
+| Outcome | `facts.source` | Meaning |
+|---|---|---|
+| Complete | `cli:extract-conversation-facts:terminal:v2` | Every eligible segment was extracted and inserted successfully, the input remained unchanged, and the terminal write succeeded. |
+| Scanned, not extractable | `cli:extract-conversation-facts:non-extractable:v2` | A recognized input was scanned successfully but contained no eligible multi-message segment. |
+| Unfinished | no matching v2 outcome | Work is pending, failed, was not recognized, changed during extraction, or has only a legacy marker. |
+
+The non-extractable outcome is intentionally separate from completion. It does
+not claim that knowledge facts were extracted. CLI counters, cycle details, and
+doctor output preserve that distinction.
+
+## Snapshot identity
+
+Every v2 marker binds `source_session` to the parser input snapshot:
+
+```text
+<outcome-source>:<page-slug>:<version-token>
+```
+
+There are two token forms.
+
+### Database-backed page body
+
+For pages parsed from `compiled_truth` and `timeline`, the token is:
+
+```text
+page-<pages.content_hash>-<effective-date>
+```
+
+`content_hash` covers title, type, compiled truth, timeline, and frontmatter.
+The effective-date suffix covers the remaining date input used by parsing. This
+identity does not depend on JavaScript's millisecond timestamp precision, so two
+writes within one PostgreSQL millisecond still produce different tokens when
+parser input changes. A legacy page with a null content hash uses a computed
+SHA-256 fallback and is verified in-process by both extraction and doctor.
+
+### Raw transcript sidecar
+
+When frontmatter contains `raw_transcript`, the source text lives outside the
+page row and may change without changing `pages.updated_at`. Its token is:
+
+```text
+sidecar-<SHA-256>
+```
+
+The digest covers the exact body given to the parser plus parser-relevant page
+metadata: title, type, frontmatter, and effective date. Selection recomputes
+the digest before skipping work. A sidecar-only edit therefore reopens the page.
+
+`gbrain doctor` cannot read sidecars in its SQL aggregate, so it enumerates those
+pages in bounded batches and calls the same canonical verifier used by
+extraction. Doctor and extraction therefore agree after sidecar-only edits.
+
+## Selection and locking
+
+Bulk extraction follows this sequence:
+
+1. Enumerate candidate pages in bounded batches.
+2. Filter candidates with matching v2 outcomes.
+3. Apply `--limit` to the remaining pages that actually need work.
+4. Acquire the source-and-slug advisory lock.
+5. Re-fetch the page under that lock.
+6. Recompute and recheck the snapshot-bound outcome.
+7. Prepare one immutable parser snapshot and process it.
+8. Re-fetch and recompute the snapshot before writing an outcome.
+
+The pre-lock check avoids parser, filesystem, and model work for ordinary
+completed pages. The under-lock refetch prevents a stale enumeration object
+from becoming the certified input. The final comparison prevents an edit that
+happens during model or insertion work from receiving a marker for old content.
+
+An edit can occur after the final comparison and before marker insertion. That
+is still safe because the marker contains the old version token. Future
+selection compares the token, not marker creation time, and reopens the page.
+
+Single-page `--slug` runs use the same under-lock path.
+
+## Strict extraction success
+
+The general `extractFactsFromTurn` API remains best-effort for interactive
+callers. It historically returns an empty array for both a legitimate zero-fact
+answer and several model failures.
+
+Conversation backfill instead uses `extractFactsFromTurnWithOutcome`, whose
+result separates:
+
+- `{ ok: true, facts: [] }`, a successful extraction with no durable facts;
+- `{ ok: true, facts: [...] }`, a successful extraction with facts; and
+- `{ ok: false, reason, error? }`, an unavailable provider, provider error,
+  refusal, content filter, malformed output, or repeated truncation.
+
+Any failed segment aborts the page attempt. Any `insertFacts` failure also
+aborts it. The page receives neither a checkpoint advancement nor a terminal
+outcome. Facts inserted by earlier segments may remain temporarily, but the
+next claim deletes this command's rows for the page and replays cleanly.
+
+Bulk workers continue past an individual page failure, but they do not hide it.
+`pages_failed` counts failed claims, stderr names each page, the CLI exits 1,
+the autopilot phase reports `warn`, and receipts/rollups classify the run as
+incomplete. A tolerant pool is therefore observable without sacrificing the
+rest of a large backfill.
+
+This distinction is load-bearing. Treating a provider outage as a successful
+zero-fact response would make a transient failure durable and permanently hide
+the page from later runs.
+
+## Non-extractable authority
+
+A non-extractable marker is written only when all of the following are true:
+
+- a deterministic or accepted parser format recognized the input;
+- ordinary segmentation produced no eligible multi-message segment;
+- the parser phase was not `no_match`;
+- cleanup of prior command-owned rows succeeded; and
+- the input snapshot was still current immediately before cleanup and write.
+
+A `no_match` result stays unfinished so a new parser pattern, optional fallback,
+or corrected input can recover it. Oversize pages, disappeared pages, lock
+contention, dry runs, aborts, cleanup errors, provider failures, extraction
+failures, insertion failures, and outcome-write failures also stay unfinished.
+
+Cleanup errors are never interpreted as "zero rows deleted." Propagating them
+prevents a fresh non-extractable marker from coexisting with stale extracted
+facts that could not be removed.
+
+## Checkpoints are not authority
+
+Operation checkpoints are only progress hints. They do not prove which page
+snapshot was processed, and old checkpoint entries do not include a snapshot
+token. When a page lacks a matching v2 outcome, the command discards that
+page's checkpoint entry and performs a delete-first full replay.
+
+This rule prevents two corruption classes:
+
+- edited text with timestamps older than the old watermark being skipped; and
+- command-owned facts being deleted while the checkpoint skips the segments
+  needed to recreate them.
+
+Deleting `op_checkpoints` does not reopen pages with matching v2 outcomes.
+Deleting or editing an outcome does not make a checkpoint authoritative.
+
+## `--limit` semantics
+
+`--limit N` caps pages that require processing, not completed pages inspected
+while finding them. Durable filtering happens before clipping a batch. With a
+completed page first and a pending page second, `--limit 1` processes the
+pending page rather than consuming the limit on the completed page.
+
+`pages_considered` may therefore exceed `--limit` because it includes durable
+outcomes observed during selection. Model-bearing page work does not exceed the
+limit.
+
+## `--force`
+
+`--force` bypasses durable outcome selection and clears the page checkpoint.
+It still uses delete-first replay, strict extraction outcomes, advisory locks,
+and snapshot verification. Force means "recompute" rather than "relax safety."
+
+## Operator signals
+
+The result exposes separate counters:
+
+- `pages_skipped_completed`
+- `pages_skipped_non_extractable`
+- `pages_marked_non_extractable`
+- `pages_failed`
+
+The CLI aggregates these across sources. The autopilot backfill phase includes
+them in phase details. `gbrain doctor` reports `completed`,
+`scanned_not_extractable`, and `backlog` independently.
+
+Run a small canary twice:
+
+```bash
+gbrain extract-conversation-facts --source-id default --limit 10 --workers 1 --max-cost-usd 0.25 --yes
+gbrain extract-conversation-facts --source-id default --limit 10 --workers 1 --max-cost-usd 0.25 --yes
+gbrain doctor
+```
+
+On the second run, unchanged pages should move through durable skip counters.
+Edit one page or raw transcript sidecar and rerun; that page should process
+again and receive a marker with a new token.
+
+## Maintainer contracts
+
+- Version completion protocols when their success guarantees change.
+- Require an exact `source`, page slug, and snapshot-bound `source_session`.
+- Keep completion and non-extractable as different sources and counters.
+- Re-fetch after acquiring the lock; never certify the enumeration object.
+- Revalidate the snapshot before writing either durable outcome.
+- Keep sidecar content in the version identity.
+- Keep regular-page content hash and effective date in the version identity.
+- Never turn model, insertion, cleanup, cancellation, or parser failures into
+  successful empty extraction.
+- Never classify `no_match` or dry-run output as a durable negative.
+- Do not make operation checkpoints completion authority.
+- Apply work limits after durable filtering.
+- Keep doctor source-scoped by both page and fact `source_id`.
+- Give terminal completion precedence if both current outcome rows exist.
+- Update CLI and cycle aggregation whenever a result counter changes.

+# Conversation parser LLM fallback
+
+The conversation parser has two stages:
+
+1. 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. Enabling it is a privacy decision
+because unmatched transcript text can be sent to the configured utility-tier
+model provider.
+
+## Enable or disable the fallback
+
+Enable it for the current brain:
+
+```bash
+gbrain config set conversation_parser.llm_fallback_enabled true
+```
+
+Disable it:
+
+```bash
+gbrain config set conversation_parser.llm_fallback_enabled false
+```
+
+The key is registered explicitly, so neither command needs `--force`.
+Values other than the exact string `true` leave the fallback disabled.
+
+The setting affects conversation fact extraction. It does not make the
+synchronous `conversation-parser scan` command call a model, and it does not
+enable the separate LLM polish scaffold.
+
+## Select the utility model and run a canary
+
+Inspect the model routing before enabling a production run:
+
+```bash
+gbrain models
+```
+
+The fallback uses the resolved `utility` tier. Override that tier when the
+brain should use a different configured provider or model:
+
+```bash
+gbrain config set models.tier.utility <provider:model>
+```
+
+Start with one known unmatched page and an explicit cost cap:
+
+```bash
+gbrain extract-conversation-facts \
+  --source-id <source-id> \
+  --slug <conversation-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 <slug>
+```
+
+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;

+- 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;

+### If agents run as containers on the same Docker host

+OAuth source scoping only guards the HTTP MCP path. If the brain's Postgres and your teammates' agent runtimes are containers on the same Docker host, make sure the agents can't reach Postgres directly over Docker's default bridge network — a direct DB session skips OAuth entirely. Put Postgres on its own user-defined network, publish it loopback-only if at all, and never hand agent containers a `DATABASE_URL`. The copy-paste operator checklist lives in [docs/mcp/DEPLOY.md — Co-located Docker workloads](../mcp/DEPLOY.md#co-located-docker-workloads-self-hosted-postgres).

+### Co-located Docker workloads (self-hosted Postgres)
+
+OAuth scopes and source scoping guard the `gbrain serve --http` path. They do
+NOT guard raw Postgres. If the brain's Postgres runs as a container on the same
+Docker host as other workloads (agent runtimes, n8n, staging fixtures), any
+container sharing Docker's default `bridge` network can open a direct DB
+session — no OAuth token required — and read every source. That silently
+recreates a privileged path underneath the isolation you configured at the MCP
+layer.
+
+Network-zone the host so untrusted containers can never reach Postgres:
+
+```
+Docker host
+├── gbrain-net          ← ONLY the brain's Postgres (+ gbrain serve, if containerized)
+├── agent-<id>-net      ← each untrusted agent runtime, isolated
+└── default bridge      ← no secret-bearing databases
+```
+
+Operator checklist:
+
+```text
+[ ] Postgres is on a user-defined Docker network, not the default bridge
+    (or nothing else runs on that bridge)
+[ ] If Postgres publishes a host port at all, it binds loopback only
+    (`-p 127.0.0.1:5432:5432`, never `0.0.0.0`)
+[ ] Untrusted agent containers have no DATABASE_URL or Postgres password
+[ ] Untrusted agents reach the brain via OAuth/Bearer against serve --http only
+    (host loopback via host.docker.internal / host gateway — never gbrain-net)
+[ ] OAuth clients are least-privilege: scoped --source / --federated-read,
+    pre-minted short-lived tokens preferred over long-lived client secrets
+[ ] Isolation verified: a team-scoped client cannot read internal-only sources
+```
+
+Optional defense-in-depth: a dedicated Postgres role (or RLS) limited to the
+allowed `source_id`s, so even a leaked connection string can't read everything.

 NOTES
-  Submitting subagent jobs is trusted-only; MCP submitters receive
-  permission_denied. The worker needs ANTHROPIC_API_KEY set, or the
-  first LLM turn of a claimed job fails.
+  This CLI path is trusted-only. (Remote MCP callers reach subagents through
+  the scoped submit_agent operation, not through this command.)
+
+  By default the worker runs the legacy Anthropic-direct path, which needs an
+  Anthropic key — from ANTHROPIC_API_KEY or from anthropic_api_key in
+  ~/.gbrain/config.json — or the first LLM turn of a claimed job fails.
+
+  To run --model on a non-Anthropic provider, enable the provider-neutral
+  gateway loop first, then supply whatever credential that provider needs
+  (an API key for most; some recipes use OAuth or a local endpoint):
+    gbrain config set agent.use_gateway_loop true
+  Accepted values: true / 1 / yes / on.
+
+  The gateway loop needs a provider whose recipe supports chat WITH tool
+  calling — not every recipe under src/core/ai/recipes/ qualifies. A model
+  that cannot call tools is refused at job start with the reason named.

- * v0.28: drift dream phase.
+ * Drift dream phase (#2653 — wired v0.42.x; scaffold shipped v0.28).
  *
- * Detects takes where the underlying evidence has shifted since the take
- * was made. v0.28 ships the SCAFFOLD: the phase iterates active takes,
- * runs a lightweight check against recent timeline entries on the same
- * page, and writes a drift-report-<date>.md if any takes look stale.
+ * Detects takes whose underlying evidence has shifted since the take was
+ * made. Two stages:
+ *   1. Cheap SQL heuristic (findDriftCandidates): soft-band takes
+ *      (weight 0.3–0.85, active, unresolved) on pages with fresh
+ *      timeline_entries evidence inside the lookback window.
+ *   2. LLM judge: each candidate's claim is compared against the recent
+ *      timeline evidence; the judge returns {drifted, confidence,
+ *      reasoning, suggested_weight}. BudgetMeter-gated.
  *
- * The full LLM-driven drift detection (compare each take's claim to recent
- * page evidence and propose a weight adjustment) is the v0.29 follow-up.
- * v0.28 lays the phase orchestration so the contract is stable.
+ * Output is REPORT-ONLY (v1 conservative posture): judged candidates land
+ * on a `reports/drift-<date>` page. `dream.drift.auto_update` mutates
+ * NOTHING in v1 — it is recorded in the report so operators can see the
+ * flag state, and a future wave may wire weight adjustment behind it.
  *
  * Default-disabled. Operator opts in:
  *   gbrain config set dream.drift.enabled true
  *   gbrain config set dream.drift.lookback_days 30
+ *   gbrain config set dream.drift.max_per_cycle 20
