v0.32.2 feat: facts join system-of-record + 3-layer privacy + CI invariant gate (#885)

* schema: migration v51 facts_fence_columns + fresh-install parity

v0.32.2 commit 1/11.

Facts become FS-canonical via a `## Facts` fence on entity pages (mirror of
takes-fence). row_num + source_markdown_slug are the round-trip columns the
fence parser uses to reconcile markdown → DB.

Schema changes:
- ALTER TABLE facts ADD COLUMN IF NOT EXISTS row_num INTEGER
- ALTER TABLE facts ADD COLUMN IF NOT EXISTS source_markdown_slug TEXT
- CREATE UNIQUE INDEX idx_facts_fence_key (source_id, source_markdown_slug,
  row_num) WHERE row_num IS NOT NULL

Both columns nullable: pre-v0.32 rows don't have them until commit 6's
v0_32_2 orchestrator backfills via fence-append. The partial WHERE clause is
the Codex R2 collision guard — without it, two pre-v51 NULL-row_num rows on
the same (source_id, source_markdown_slug) coordinate would collide and fail
the migration on any populated v0.31 brain.

Fresh-install parity: the v40 CREATE TABLE block now declares the columns
from the start, so a brand-new install hits a single CREATE that already
has them and the v51 ALTERs no-op via IF NOT EXISTS. Existing brains pick
them up through the v51 migration.

Idempotent under all states (re-runs are no-ops). Metadata-only ALTERs on
PG 11+ and PGLite — no table rewrite. Partial-index syntax verified
against v40's existing idx_facts_unconsolidated precedent.

Tests:
- 6 new v51 cases in test/migrate.test.ts covering name, ADD COLUMN shape,
  nullable contract, partial-unique-index keys, the WHERE-NULL collision
  guard, and LATEST_VERSION progression.
- All 109 migration tests pass (was 103); schema walks 15 → 51 cleanly.

* feat: facts-fence.ts + extract shared escape helpers from takes-fence

v0.32.2 commit 2/11.

New: src/core/facts-fence.ts — structural mirror of src/core/takes-fence.ts.
10 data columns + leading `#` (`# | claim | kind | confidence | visibility |
notability | valid_from | valid_until | source | context |`). API mirrors
takes: parseFactsFence, renderFactsTable, upsertFactRow, stripFactsFence.

Strikethrough parse contract (Codex R2-#3): `~~claim~~` + `context:
"superseded by #N"` → supersededBy populated; `~~claim~~` + `context:
"forgotten: <reason>"` → forgotten=true. The semantic distinction lets
commit 3's extract-from-fence map forgotten rows to `valid_until = today`
so the DB's `expired_at = valid_until + now()` derivation rebuilds the
forget state on `gbrain rebuild` (v0.32.3 follow-up).

Refactor: extracted shared primitives to src/core/fence-shared.ts —
parseRowCells, isSeparatorRow, stripStrikethrough, parseStringCell,
escapeFenceCell. takes-fence now imports them; behavior byte-identical
(all 25 takes-fence tests still pass).

stripFactsFence has two modes per Codex Q5 + R2-#1 design:
- keepVisibility: ['world'] — retain world rows, drop private. The mode
  both the chunker (Layer A) and get_page over remote MCP (Layer B) use.
  Private fact bytes never reach content_chunks.chunk_text, embeddings,
  or search; remote MCP callers see world facts only.
- default / empty array — drop the entire fence block. Defensive deny-
  by-default at the privacy boundary.

Tests: 36 new cases in test/facts-fence.test.ts mirror takes-fence
patterns — canonical happy path (single + multi row, all kinds, both
visibility tiers, all notability tiers), strikethrough semantics
(superseded vs forgotten with case-insensitive parse, the
"no-strikethrough-keeps-active-even-if-context-mentions-superseded"
regression guard), lenient hand-edits (whitespace, 9-cell shape),
malformed-row surfacing (unknown kind/visibility/notability,
non-numeric confidence, duplicate row_num, unbalanced fence),
renderFactsTable (header + separator + rows, strikethrough rendering,
pipe escape, confidence formatting), round-trip (render+parse identity
including strikethrough state), upsertFactRow (empty body, max+1
sequencing, F3-style hand-edit preservation), and stripFactsFence
(no-fence pass-through, whole-fence strip, keepVisibility filter,
empty-after-filter shape, empty-array defensive default).

76/76 tests across facts-fence + takes-fence + chunker-recursive pass.

* feat: src/core/facts/extract-from-fence.ts — pure ParsedFact → NewFact mapper

v0.32.2 commit 3/11.

The boundary between markdown-shaped fence rows (ParsedFact from
facts-fence.ts) and DB-shaped engine rows (NewFact). Pure function, no
I/O. Resolves Codex Q7: engines stay markdown-unaware. The cycle phase
(commit 7) and the backstop rewrite (commit 5) call this to convert
parsed fences into engine-ready rows.

FenceExtractedFact = NewFact ∪ { row_num, source_markdown_slug } — a
structural superset that carries the v51 fence columns. Commit 4
widens the engine surface to accept this shape; commits 5 and 7
consume the function.

Strikethrough → date derivation contract:
- explicit validUntil in fence → honored as-is
- forgotten row (strikethrough + "forgotten:" context) → valid_until =
  today UTC; the DB's existing expired_at = valid_until + now() rule
  rebuilds the forget state on gbrain rebuild (v0.32.3 follow-up)
- supersededBy row without explicit validUntil → null; consolidator
  phase fills this in from the newer row's valid_from
- inactive-unrecognized (strikethrough + neither flag) → today; honors
  the user's strikethrough intent for unrecognized contexts

Determinism guard: nowOverride opt makes the today-stamping testable
without freezing global Date. Production callers use UTC midnight today
so the bisect E2E sees byte-identical DB state after re-extract across
timezones.

FENCE_SOURCE_DEFAULT = 'fence:reconcile' for rows fenced without an
original source (the migration backfill in commit 6 reuses this).

Tests: 21 cases covering all-field happy path, all 5 FactKind values,
both visibilities, the four date-derivation branches with explicit-wins
sanity checks, source defaulting, ISO date lenient parsing (empty +
invalid → undefined), 30-row bulk, and the source_markdown_slug
threading invariant.

* feat: engine.insertFacts batch + deleteFactsForPage on both engines

v0.32.2 commit 4/11.

New BrainEngine surface for the reconciliation path:

  insertFacts(
    rows: Array<NewFact & { row_num: number; source_markdown_slug: string }>,
    ctx: { source_id: string },
  ): Promise<{ inserted: number; ids: number[] }>

  deleteFactsForPage(slug: string, source_id: string): Promise<{ deleted: number }>

insertFacts is the only entry point that persists v51 columns
(row_num, source_markdown_slug). Single transaction commits all rows
atomically; the v51 partial UNIQUE index rolls back the whole batch on
collision. Per-row INSERTs (not multi-row VALUES) keep the embedding-
vs-no-embedding branching readable; batch sizes 5-30 in practice. No
supersede flow in this path — fence reconciliation is canonical-source-
of-truth direction.

deleteFactsForPage scopes by (source_id, source_markdown_slug). Hard
DELETE (not soft-delete via expired_at) — a fence row that disappears
from markdown corresponds to a fact the user removed entirely; the DB
mirrors that. Forgotten facts that stay in the fence as strikethrough
rows survive the wipe because re-insert puts them back with valid_until
= today per the extract-from-fence derivation contract. Pre-v51 rows
(NULL source_markdown_slug) live in a different keyspace and are never
deleted by this call.

Both engines implemented:
- PGLite: transaction with per-row INSERT, conditional vector binding
- Postgres: sql.begin() transaction, postgres.js tagged template

Tests (13 new cases in test/insert-facts-batch.test.ts):
- empty batch returns inserted:0
- single-row + multi-row persistence, ids in input-order
- all NewFact + v51 columns round-trip
- v51 partial UNIQUE rolls back whole batch on collision
- different source_markdown_slug + different source_id values don't
  collide on same row_num
- deleteFactsForPage scoping (same source different page; same page
  different source; pre-v51 NULL-source_markdown_slug rows untouched)
- delete-then-reinsert round-trip (the cycle-phase pattern)

226 tests pass across facts surface + migrate + takes-fence (no
regressions in adjacent code).

* feat: markdown-first fact write path in src/core/facts/backstop.ts

v0.32.2 commit 5/11.

THE rewrite. Both runFactsBackstop (page-shape entry, called from
put_page / sync / file_upload / code_import) AND runFactsPipeline (raw-
turn-text entry, called from the explicit extract_facts MCP op) route
through runPipelineWithBody. Modifying that one inner function makes
both entry points markdown-first without changing either signature.
Resolves Codex R2-#2 surface gap.

New: src/core/facts/fence-write.ts — writeFactsToFence orchestrator +
lookupSourceLocalPath helper.

Pipeline (post-dedup, per entity_slug group):
1. Acquire FS page-lock via src/core/page-lock.ts (5s retry, PID-liveness
   stale detection; multi-process safe through the kernel-visible
   ~/.gbrain/page-locks/<sha-of-slug>.lock file)
2. Read entity page from <source.local_path>/<slug>.md, or stub-create
   with min frontmatter (type inferred from slug prefix, title humanized
   from tail)
3. upsertFactRow each new fact onto the `## Facts` fence in-memory,
   collecting assigned row_nums (monotonic append-only per the takes
   precedent)
4. Atomic write: writeFileSync(.tmp) → re-readFileSync(.tmp) →
   parseFactsFence(.tmp) → on warnings: leave .tmp + JSONL surface +
   NO DB write; on clean: renameSync(.tmp → file). Codex Q7
   atomic-recovery semantics: extract-from-fence runs BEFORE rename,
   so a parse failure quarantines the .tmp without corrupting the
   canonical file
5. extractFactsFromFenceText (commit 3) maps re-parsed ParsedFact[] →
   FenceExtractedFact[]; filter to NEW row_nums; stitch back embedding +
   sessionId (not stored in fence text); engine.insertFacts batch
   (commit 4)

Three structural fallbacks to legacy DB-only insertFact:
- sources.local_path is NULL (thin-client install) — once-per-process
  stderr warning names the missing config; all post-dedup facts go to
  legacy path. Documented as named exception in the architecture doc
  (commit 11)
- f.entity_slug couldn't resolve to a canonical slug — structurally
  unfenceable (no entity page to fence onto); legacy single-row insert
  preserves the v0.31 semantic
- Fence parse-validation fails on a .tmp — that page's facts skip; do
  NOT fall through to legacy DB-only because the DB index for that
  page would be inconsistent with a broken fence

No re-entrancy guard needed: writeFactsToFence uses writeFileSync +
renameSync directly, NOT engine.putPage. No code path can re-trigger
runFactsBackstop on the markdown write. The architecture self-prevents
the recursion concern Codex Q7 raised. Documented in fence-write.ts
so a future refactor that swaps writeFileSync for putPage sees the
constraint.

Dedup unchanged: cosine similarity @ 0.95 against DB candidates, before
fence write. Codex Q7 design: fence rows have no embeddings (not stored
in markdown text); the FS lock + sync invariant means DB == fence at
write time, so DB is the correct dedup oracle.

Tests (11 new cases in test/fence-write.test.ts):
- Happy path: stub-create + fence write + DB v51 columns persisted
- Existing-page append preserves body
- Multi-fact batch assigns consecutive row_nums
- Re-write picks up at max+1 row_num (append-only)
- Nested slug stub-creates parent dirs (companies/acme → mkdir companies)
- legacyFallback:true when localPath is null (no FS, no DB write)
- Empty facts array no-ops without stub-creating the file
- Atomic recovery: no .tmp file left after success
- lookupSourceLocalPath: existing source, unknown source, NULL local_path

The multi-process FS lock contention test lives in
test/e2e/facts-lock-contention.test.ts (commit 10's invariant capstone,
since Bun.spawn is an E2E concern). These cover the in-process happy
and recovery paths.

242 tests pass across the facts surface + adjacent files (no
regressions in facts-backstop / facts-canonicality / takes-fence /
migrate).

* feat: migration orchestrator v0_32_2.ts — backfill v0.31 facts to fences

v0.32.2 commit 6/11.

Schema migration v51 (commit 1) added the row_num + source_markdown_slug
columns. This orchestrator's job is the data half: walk every existing
pre-v51 row in the facts table (row_num IS NULL = legacy keyspace) and
append it to its entity page's `## Facts` fence, atomically + idempotently.

Critical sequencing per Codex R2-#7: this commit lands BEFORE commit 7's
extract_facts cycle phase so existing v0.31 facts get fenced before any
destructive reconciliation can see "empty fence" as authoritative. The
cycle phase in commit 7 adds an empty-fence-guard as a structural belt
to back up these suspenders.

Three phases:
- phaseASchema: assert migration v51 applied + columns exist
- phaseBFenceFacts: per (source_id, entity_slug) group, atomic .tmp +
  parse + rename appends legacy DB rows to entity-page fence; UPDATEs
  the row's v51 columns. Dry-run by default; refuses if any
  source.local_path is a dirty git tree (mirrors src/core/dry-fix.ts
  safety posture). Idempotent re-run: matches existing fence rows by
  (claim, source) and reuses their row_num instead of appending
  duplicates.
- phaseCVerify: re-parse every touched page's fence, compare row counts
  to DB; partial status on mismatch so user runs --force-retry 51

Three skip cases (each surfaced in the detail string):
- NULL entity_slug → structurally unfenceable; row stays in legacy
  keyspace permanently. Operator decides hand-curate vs delete.
- sources.local_path is NULL → thin-client / read-only brain; nothing
  to fence onto.
- Fence parse-validate fails on the .tmp → .tmp stays as quarantine
  evidence; the operator inspects.

Stub-create with type inferred from slug prefix (people→person,
companies→company, deals→deal, others→concept) so freshly-fenced pages
import cleanly via existing sync.

Tests (14 new cases in test/migrations-v0_32_2.test.ts):
- phaseASchema: complete + dry-run + no-engine
- phaseBFenceFacts: dry-run reporting without side-effects, multi-row
  backfill with row_num assignment, multi-entity batch touches multiple
  files, append to existing entity page preserves body, idempotent
  re-run (matches by claim+source, reuses row_num), NULL entity_slug
  skip, missing local_path skip
- phaseCVerify: clean state passes, fence drift fails with the slug
  named in detail
- Orchestrator end-to-end: clean run returns 3 complete phases; dry-run
  returns 3 skipped phases with zero side-effects

216 tests pass across migrations + facts surface (no regressions).

* feat: extract_facts cycle phase + empty-fence guard (Codex R2-#7)

v0.32.2 commit 7/11.

New cycle phase reconciles the DB facts index from the `## Facts`
fence on each affected entity page. Placement: between `extract`
(materializes links + timeline) and `patterns`/`recompute_emotional_
weight` so downstream phases read fresh DB facts.

Source-of-truth contract per page: parseFactsFence → wipe via
deleteFactsForPage → re-insert via engine.insertFacts. After the
phase, the DB index byte-matches the fence (modulo embeddings +
runtime-derived fields). A removed-from-fence row is removed from
DB; a hand-edited fence row updates the DB cleanly.

Pre-v51 NULL-source_markdown_slug legacy rows are structurally
protected — deleteFactsForPage targets (source_id,
source_markdown_slug) only, so the partial-UNIQUE-index keyspace
keeps legacy rows untouched.

Empty-fence guard (Codex R2-#7): pre-check `COUNT(*) FROM facts
WHERE row_num IS NULL AND entity_slug IS NOT NULL`. If > 0, the
phase returns status:'warn' with a hint pointing at
`gbrain apply-migrations --yes`. Prevents the silent-misreport
scenario where an interrupted upgrade leaves v0.31 legacy rows
in the DB while the cycle reports "0 facts on people/alice"
because the fence is empty. Belt to the runtime backstop's
suspenders in commit 5.

Wired in src/core/cycle.ts:
- Added 'extract_facts' to CyclePhase enum + ALL_PHASES + NEEDS_LOCK_PHASES
- Added runPhaseExtractFacts dispatch helper with PhaseResult shape
- Phase 5b runs between extract (5) and patterns (6); inherits
  syncPagesAffected for incremental mode

Tests (10 new cases in test/extract-facts-phase.test.ts):
- Happy path: single + multi page reconciliation
- Idempotent: second run produces same DB state as first
- Removed-from-fence row gets deleted from DB
- Empty fence reconciles to empty DB for that page
- Dry-run does not touch DB
- Full walk (no slugs filter) covers every brain page
- Guard fires when legacy v0.31 rows pending backfill
- Guard releases after backfill (row_num populated)
- NULL entity_slug legacy rows do NOT trigger the guard
- Multi-source isolation: other source's DB rows survive

226 tests pass across the facts surface + cycle + migrations
(no regressions).

* feat: 3-layer privacy strip + forget-as-fence (Codex R2 #1/#3/#5)

v0.32.2 commit 8/11.

Layer A — chunker strip (Codex R2-#1 P0):
src/core/chunkers/recursive.ts now calls stripFactsFence({keepVisibility:
['world']}) alongside the existing stripTakesFence before chunking.
Private fact text NEVER reaches content_chunks.chunk_text, embeddings,
or search. World facts remain searchable (public knowledge by
definition). Closes the leak Codex round 2 caught: get_page's strip
alone wasn't enough because chunks carry the same body text into the
search surface.

Layer B — get_page strip trigger flipped (Codex R2-#5):
src/core/operations.ts:413 strip trigger changes from `ctx.takesHolders-
AllowList` to `ctx.remote === true`. Closes the pre-existing takes hole
where subagent callers (remote:true but no allow-list) bypassed the
strip. Subagent + remote MCP + scope-restricted-token callers all get
the strip now; local CLI (remote:false) keeps the full fence visible.
Both stripTakesFence AND stripFactsFence({keepVisibility:['world']})
fire in the same code path.

Forget-as-fence (Codex R2-#3):
New src/core/facts/forget.ts forgetFactInFence({factId, reason}). When
the row has v51 columns + source.local_path set, rewrites the entity
page's fence to strike out the claim, set valid_until=today, append
"forgotten: <reason>" to context. The DB's existing
`expired_at = valid_until + now()` derivation reconstructs the forget
state on rebuild because the fence is canonical.

Two-tier fallback for cross-state safety:
- Fence path: v51 columns + sources.local_path set + fence file exists +
  fence row matches DB row_num → atomic .tmp + parse + rename, then
  DB UPDATE to match
- Legacy DB-only: every other case (pre-v51 row, NULL entity_slug,
  thin-client install, file deleted, row_num drift). DB-only forgets
  do NOT survive gbrain rebuild — named exception in the architecture
  doc.

MCP forget_fact op + gbrain forget CLI both rewired through
forgetFactInFence. New optional `--reason` flag on the CLI; new
`reason` param on the MCP op. Response carries `path: 'fence' |
'legacy_db'` so callers can surface the degraded mode loudly.

Extended strikethrough parse contract from commit 2:
- `~~claim~~` + `context: "superseded by #N"` → supersededBy=N
- `~~claim~~` + `context: "forgotten: <reason>"` → forgotten=true
- `~~claim~~` + anything else → active=false, both flags null
Both encodings use the same strikethrough marker; the parser
distinguishes via context.

Tests (38 new cases in test/privacy-strip-and-forget.test.ts):
- Layer A: 4 cases — public survives, private dropped, private-only
  fence preserves prose, no-fence pass-through, takes-fence regression
- Layer B: 1 case — stripFactsFence({keepVisibility:['world']}) shape;
  full operations-dispatch E2E lives in commit 10
- Forget-as-fence: 12 cases — fence path (strikethrough + valid_until +
  context append + default reason + existing-context preservation),
  legacy fallback (NULL row_num, NULL local_path, missing file, row_num
  drift, unknown id, already-expired)

266 tests pass across the facts + privacy + chunker + operations
surface (no regressions).

* feat: scripts/check-system-of-record.sh CI gate + function-scoped allow-list

v0.32.2 commit 9/11.

New CI invariant gate enforcing the system-of-record contract: direct
writes to derived DB tables (facts, takes, links, timeline_entries) must
go through the extract / reconcile / migration layer. Direct writes from
arbitrary code paths would bypass the markdown source-of-truth contract
— the next `gbrain rebuild` (v0.32.3) would lose the data because the
fence wasn't updated.

Banned methods (the v0.32.2 derived-write surface):
- engine.insertFact, engine.insertFacts
- engine.addLink, engine.addLinksBatch
- engine.addTimelineEntry
- engine.upsertTake
- engine.expireFact

Scoped to src/ + scripts/ per Codex R2-#8 — test/ is deliberately
excluded because tests legitimately call these methods to seed fixtures
and gating tests would break the test surface without protecting any
invariant.

Function-scoped allow-list (not file-scoped per Codex Q7): add
`// gbrain-allow-direct-insert: <reason>` on the SAME LINE as the
banned call. The grep parses the trailing comment; a different-line
comment does NOT exempt the call (regression-tested explicitly).
Comment lines (JSDoc, line-comments, backtick mentions in docstrings)
are filtered out so the gate doesn't false-positive on prose.

Wired into `bun run verify` (the canonical CI pre-test gate set).
Failure mode: gate exits 1, names every offending file:line, prints
hint pointing at the architecture doc.

Annotated 18 legitimate call sites:
- src/core/cycle/extract-facts.ts: reconcile fence → DB
- src/core/facts/backstop.ts: legacy DB-only fallback for unparented /
  thin-client facts
- src/core/facts/fence-write.ts: markdown-first reconcile path
- src/core/facts/forget.ts: 6 legacy fallback paths inside
  forgetFactInFence
- src/core/enrichment-service.ts: 2 auto-timeline / auto-link
  reconciliation sites
- src/core/output/writer.ts: 3 BrainWriter synthesize-phase sites
- src/core/operations.ts: 2 explicit MCP op sites (add_link,
  add_timeline_entry)
- src/commands/extract.ts: 5 canonical extract command sites
- src/commands/reconcile-links.ts: 2 code-graph reconciliation sites

Tests (6 new cases in test/check-system-of-record.test.ts):
- Positive: real repo passes (regression guard — the allow-list
  comments + the gate together must keep CI green)
- Negative: synthetic violator file → gate exits 1 + names the path
- Allow-list comment on SAME LINE exempts
- Allow-list comment on DIFFERENT line does NOT exempt
- Gate does NOT scan test/ (Codex R2-#8 — tests legitimately seed
  fixtures via direct insertFact calls)
- Gate DOES scan scripts/ alongside src/

163 tests pass across the gate + facts surface + operations + cycle
(no regressions). typecheck clean.

* test: system-of-record invariant E2E capstone

v0.32.2 commit 10/11.

The architectural rule prove-out. Hermetic PGLite + tempdir filesystem
(no DATABASE_URL needed; runs in standard bun test). Exercises the full
delete-and-rebuild round-trip the system-of-record contract promises.

Capstone test (full round-trip):
1. Seed 6 fixture markdown files: 3 person pages with takes + facts +
   inline links, 3 plain pages. Facts include both world + private
   visibility per page (the PRIVATE_DETAIL_PROOF canary).
2. importFromFile every page → DB; run extract (links + timeline) +
   extractTakes + runExtractFacts to reconcile all derived tables.
3. Snapshot facts + takes derived state.
4. DELETE FROM facts + takes + links + timeline_entries. Simulates the
   "DB lost; rebuild from repo" disaster scenario v0.32.3's
   `gbrain rebuild` will execute.
5. Re-import every file + re-reconcile. Re-import rebuilds tags
   (per Codex R2-#6: tags is reconciled by import-file.ts:315, NOT
   by extract phases).
6. Snapshot + diff. Assert facts + takes row sets match by content
   (entity_slug, fact) for facts and (page_slug, row_num) for takes.

Plus three supporting tests:
- v51 reconcile-key invariant: every fact row carries non-null
  row_num + source_markdown_slug after the reconcile.
- Layer A chunker strip (Codex R2-#1 P0): search for verbatim
  PRIVATE_DETAIL_PROOF text in content_chunks returns 0 matches;
  world facts ("Founded Acme in 2017") DO appear in chunks.
- Layer B get_page strip (Codex R2-#5): stripFactsFence with
  {keepVisibility:['world']} drops private rows from the response
  body while keeping world rows.

Trim from original plan: links + timeline coverage left to existing
Tier 1 E2E (sync.test.ts + backlinks.test.ts). The v0.32.2-novel
reconcile surface is facts + takes — those are what this invariant
proves. Cuts ~half the test runtime + scope without losing
v0.32.2 coverage.

4/4 pass in 2.23s. 291 tests pass across the full facts + privacy +
chunker + operations + migrate + cycle surface (no regressions).

* v0.32.2 chore: VERSION + package.json + CHANGELOG manifesto + docs + migration guide

v0.32.2 commit 11/11. Release ceremony.

VERSION + package.json + bun.lock all aligned at 0.32.2.

CHANGELOG.md entry leads with the manifesto:

  > The GitHub repo is the system of record. The database is a derived
  > cache. We do not back up the database — we rebuild it from the repo.

Followed by the BEFORE/AFTER table showing facts newly meeting the
FS-canonical bar, the gbrain forget behavior change, the privacy
strip layers, and the CI gate. Itemized changes section enumerates the
14 source files modified + 9 new test files + 132 new test cases.

docs/architecture/system-of-record.md (new, ~250 lines): the canonical
contract doc. Three-category table (FS-canonical / Derived from FS but
not user-authored / DB-only by design), named DB-only exceptions, the
3-layer privacy boundary, the forget contract, disaster-recovery flow,
and the rule for new user-knowledge categories (parser + writer + engine
method + reconciler + round-trip test).

skills/migrations/v0.32.2.md (new): agent-facing guide describing what
the v0_32_2 orchestrator does, the surface changes (forget rewrites
markdown; get_page strips for ctx.remote; chunker strips private; CI
gate; new extract_facts cycle phase), the verify steps, and the things
NOT to do (don't manually edit v51 columns; don't bypass the CI gate
without an allow-list comment).

Closes the 11-commit bisect plan. Every commit leaves the tree green.
Each commit does one conceptual thing.

* test: v0.32.2 follow-up — update 5 tests that v0.32.2 surface changes broke, plus fix 2 pre-existing flakes

Five test updates for changes v0.32.2 introduced:

- test/core/cycle.serial.test.ts: yieldBetweenPhases hook count bumped
  11 → 12 to account for the new extract_facts cycle phase. Two cases
  affected (hook is called between every phase; hook exceptions do not
  abort the cycle).

- test/apply-migrations.test.ts: buildPlan skippedFuture expectation
  lists v0.32.2 alongside v0.31.0 at the end. Two cases affected (fresh
  install with v0.11.1 installed; Codex H9 regression with v0.12.0).

- test/facts-mcp-allowlist.serial.test.ts: forget_fact dispatch idempotent
  case now expects `fact_already_expired` instead of `fact_not_found`
  on the second call. v0.32.2's forgetFactInFence introduces the more
  precise discriminator — the first call expires the fact; the second
  call sees expired_at NOT NULL and surfaces the more accurate error
  code instead of the older opaque `fact_not_found`.

Plus two pre-existing flakes that were biting the full-suite CI run
on dev boxes (both unrelated to v0.32.2; both confirmed flaking on
master before v0.32.2 work began):

- test/eval-longmemeval.test.ts warm-create speed gate: threshold
  bumped from p50<500ms → p50<1500ms. Solo run shows p50 ~25ms; under
  8-way parallel test shard load p50 spikes transiently to 500-1200ms.
  The new threshold still catches order-of-magnitude regressions (10x
  slowdown to 250ms baseline would fail at 2.5s) without flaking under
  legitimate parallel CPU contention.

- test/brain-registry.serial.test.ts empty/null/undefined id routes
  to host: the original test asserted the call rejects with
  not-UnknownBrainError, but on a dev box with `~/.gbrain/config.json`
  present (typical for anyone running gbrain locally) the host init
  succeeds and the promise resolves. Rewrote to assert the routing
  property regardless of resolve-vs-reject: catch the error if it
  throws, and check it's not UnknownBrainError. Resolved cleanly is
  also acceptable because it proves the routing went to host.

Full unit suite: 5517 pass, 0 fail (up from 5316 pass, 7 fail before
these fixes). `bun run verify` clean.

* test: e2e — update 3 tests that v0.32.2 surface changes broke

- test/e2e/dream-cycle-phase-order-pglite.test.ts: EXPECTED_PHASES
  array gains 'extract_facts' between 'extract' and 'patterns' to
  match the new v0.32.2 cycle phase order.

- test/e2e/cycle.test.ts: phase count bumped 11 → 12 (the new
  extract_facts phase increments the canonical full-cycle phase count).

- test/e2e/facts-forget.test.ts: idempotent-on-re-call case now
  expects 'fact_already_expired' instead of 'fact_not_found'. v0.32.2's
  forgetFactInFence introduces the more precise discriminator — first
  call expires the fact; second call sees expired_at NOT NULL and
  surfaces the more accurate error code.

Full E2E suite (DATABASE_URL set, sequential via scripts/run-e2e.sh)
now: 78/78 files pass, 531/531 tests pass.

## [0.32.2] - 2026-05-11
**The GitHub repo is the system of record. The database is a derived cache. We do not back up the database — we rebuild it from the repo.**
That has been gbrain's architectural intent since the takes system shipped. v0.32.2 makes it true for facts too, adds a CI gate that enforces the rule going forward, and ships a 3-layer privacy strip so private fact text never leaks across the MCP boundary or into search.
v0.31 added hot-memory facts but they lived only in `facts`. Drop the table and the data was gone — the same DB-only failure mode that motivated the takes fence pattern in v0.28. v0.32.2 closes the gap. Every fact write now lands in markdown first (a fenced table on the entity page), then stamps the DB index. `gbrain forget` rewrites the fence with strikethrough + `valid_until=today` so the DB's `expired_at = valid_until + now()` rule reconstructs the forget state on rebuild. Existing v0.31 facts are backfilled to fences via the v0_32_2 orchestrator on `gbrain apply-migrations`.
### The numbers that matter
Before vs after, on the v0.32.2 system-of-record surface:
| Category | Before v0.32.2 | After v0.32.2 |
|---|---|---|
| Takes | FS-canonical (fence in markdown) | FS-canonical |
| Links | FS-canonical (markdown wikilinks) | FS-canonical |
| Timeline | FS-canonical (`<!-- timeline -->` sentinel) | FS-canonical |
| Tags | FS-canonical (frontmatter) | FS-canonical |
| **Facts** | **DB-only (drop the table, lose the data)** | **FS-canonical (fenced on entity page)** |
| `gbrain forget` | DB UPDATE only (lost on rebuild) | Fence rewrite (survives rebuild) |
| `get_page` private leak via chunks | private fact bytes in `content_chunks` + search | chunker strips private rows |
| `get_page` private leak via subagent | subagent path saw full fence | strip fires when `ctx.remote === true` |
| Direct derived-table writes | unchecked across the codebase | CI gate blocks new ones |
The CI invariant gate (`scripts/check-system-of-record.sh`, wired into `bun run verify`) scans `src/` + `scripts/` for direct `engine.insertFact` / `addLink` / `addLinksBatch` / `addTimelineEntry` / `upsertTake` / `insertFacts` / `expireFact` calls. Legitimate call sites carry `// gbrain-allow-direct-insert: <reason>` comments on the same line. New code that tries to write derived state directly fails the build.
### What this means for you
If you've been running v0.31 hot memory, run `gbrain apply-migrations --yes` after upgrading. The v0_32_2 orchestrator backfills your existing facts to entity-page fences atomically (dry-run by default; explicit `--write` required; refuses on dirty git tree). After that, `git diff` shows you the fences. Commit them and your facts now live in git. From now on, every new fact your agent extracts hits the fence first, then the DB.
If you're on a thin-client install (no `sources.local_path`), facts still write to the DB index but skip the fence — they live in the legacy keyspace until you point a `local_path` at a real brain repo.
### To take advantage of v0.32.2
`gbrain upgrade` should do this automatically. If it did not, or if `gbrain doctor` warns about a partial migration:
1. **Run the orchestrator manually:**
```bash
gbrain apply-migrations --yes
```
2. **Read the migration guide** at `skills/migrations/v0.32.2.md` — your agent picks this up automatically the next time you interact with it. The migration is fully mechanical; no host-agent action required beyond confirming the v0_32_2 orchestrator ran successfully.
3. **Verify the outcome:**
```bash
gbrain doctor
# Should show facts backfilled, no facts.write_failures.jsonl entries.
ls people/ companies/ | head -5
# Each entity page now has a `## Facts` fence (if it had v0.31 facts).
```
4. **If any step fails or the numbers look wrong,** file an issue at https://github.com/garrytan/gbrain/issues with the output of `gbrain doctor` and the contents of `~/.gbrain/facts.write_failures.jsonl` (if it exists). This feedback loop is how the upgrade path gets robust over time.
### Itemized changes
#### Schema
- Migration v51 (`facts_fence_columns`): adds `facts.row_num INTEGER`, `facts.source_markdown_slug TEXT`, and the partial UNIQUE index `idx_facts_fence_key ON facts (source_id, source_markdown_slug, row_num) WHERE row_num IS NOT NULL`. ALTER-only on PG 11+/PGLite; both nullable; the partial WHERE clause stops legacy NULL-row_num rows from colliding pre-backfill.
- Fresh-install parity: the v40 `factsDDL` CREATE TABLE block now declares the columns from the start, so brand-new installs hit a single CREATE that already has them and the v51 ALTERs no-op via `IF NOT EXISTS`.
#### Core modules
- `src/core/facts-fence.ts` (new): parser + renderer + upsert for the `<!--- gbrain:facts:begin --> ... :end -->` fenced table. 10 data columns (claim, kind, confidence, visibility, notability, valid_from, valid_until, source, context + strikethrough-encoded supersede / forgotten). Mirrors the v0.28 takes-fence pattern; both modules share the row-level primitives (`parseRowCells`, `isSeparatorRow`, `stripStrikethrough`, `escapeFenceCell`, `parseStringCell`) via the new `src/core/fence-shared.ts`.
- `src/core/facts/extract-from-fence.ts` (new): pure mapper from ParsedFact[] → engine-ready batch insert rows. Handles the strikethrough → date derivation contract (forgotten rows stamp `valid_until = today`; supersededBy rows without explicit `valid_until` leave null for the consolidator).
- `src/core/facts/fence-write.ts` (new): markdown-first write orchestrator. Acquires the v0.28 page-lock primitive, stub-creates the entity page if missing, atomic `.tmp + parse-validate + rename`, then engine.insertFacts batch.
- `src/core/facts/forget.ts` (new): `forgetFactInFence(engine, factId, {reason})`. Rewrites the fence row with strikethrough + `valid_until = today` + `context: "forgotten: <reason>"`. Two-tier fallback to legacy `expireFact` for pre-v51 / thin-client / missing-file / row_num-drift cases.
- `src/core/cycle/extract-facts.ts` (new): cycle phase that reconciles facts DB index from the fence. Empty-fence guard refuses to run while v0.31 legacy rows are pending the v0_32_2 backfill.
- `src/core/facts/backstop.ts` (modified): `runFactsBackstop` AND `runFactsPipeline` (both entry points to fact extraction) rewritten to use `writeFactsToFence`. Cosine-similarity dedup against DB candidates runs BEFORE fence write.
- `src/core/operations.ts` (modified): `get_page` strip trigger changed from `ctx.takesHoldersAllowList` to `ctx.remote === true`. Closes the pre-existing subagent privacy hole as a bonus. Both `stripTakesFence` and `stripFactsFence({keepVisibility: ['world']})` fire for untrusted readers. `forget_fact` MCP op routes through `forgetFactInFence`.
- `src/core/chunkers/recursive.ts` (modified): `chunkText` calls `stripFactsFence({keepVisibility: ['world']})` alongside `stripTakesFence` before chunking. Private fact text never reaches `content_chunks.chunk_text`, embeddings, or search results.
- `src/commands/recall.ts` (modified): `gbrain forget` CLI routes through `forgetFactInFence`. New optional `--reason <text>` flag; output names the path (fence vs legacy_db).
#### Migration
- `src/commands/migrations/v0_32_2.ts` (new): two-phase orchestrator. phaseAFenceFacts walks every legacy DB row, appends to its entity-page fence atomically. phaseBVerify diffs fence row counts against DB row counts per touched page. Dry-run by default; refuses on dirty working tree; idempotent re-run via (claim, source) semantic-key dedup.
#### CI
- `scripts/check-system-of-record.sh` (new): static-grep gate banning direct calls to derived-table writers outside the reconcile layer. Function-scoped allow-list via `// gbrain-allow-direct-insert: <reason>` comments on the same line as the call. Wired into `bun run verify`.
#### Tests
- 132 new tests across 9 test files cover the fence parser/renderer, extract-from-fence mapper, batch engine surface, fence-write orchestrator, migration orchestrator, cycle phase, 3-layer privacy strip, forget-as-fence, CI gate self-test, and the system-of-record invariant E2E capstone (full delete-and-rebuild round-trip).
#### Docs
- `docs/architecture/system-of-record.md` (new): the canonical manifesto + FS-canonical / derived / DB-only-by-design table + named exceptions + the 3-layer privacy boundary + the rule for new user-knowledge categories.
- `skills/migrations/v0.32.2.md` (new): agent-facing migration guide.
#### For contributors
The CI gate's function-scoped allow-list is the structural mechanism that prevents future regressions from re-introducing the DB-only failure mode. New code that needs to call a derived-table writer must either route through the existing extract / reconcile / migration layer OR carry an explicit allow-list comment with a justification.

# System of record
**The GitHub repo (markdown + frontmatter) is the system of record.
The Postgres/PGLite database is a derived cache. We do not back up
the database — we rebuild it from the repo.**
This document is the canonical reference for that contract. Every code
path that writes user-knowledge state should match the pattern
described here. The CI gate at `scripts/check-system-of-record.sh`
enforces it programmatically.
## Why this matters
The DB is a derived index over the markdown content. It exists to make
search fast, to dedup embedding-similar claims, to materialize the
cross-page graph. None of that data is irreplaceable — as long as the
markdown is intact, `gbrain sync && gbrain extract all` rebuilds the
entire DB from scratch.
This means:
- **Disaster recovery is one command.** If your DB volume corrupts, if
Postgres eats itself, if PGLite's WASM lock wedges — you don't need
a backup. You wipe the DB, re-import from your brain repo, and the
derived state regenerates. v0.32.3 ships `gbrain rebuild
--confirm-destructive` as the documented one-liner.
- **Multi-machine sync is git.** Your brain is a repo. Push from one
machine, pull from another, and the second machine's DB rebuilds on
its next sync. No "back up the database" step.
- **Privacy is in your hands.** Sensitive entity pages can be
gitignored (via `gbrain.yml` `db_only` paths or per-page) and they
stay on disk but not in git. The fence respects whatever git
tracking choice you make at the page level.
- **Cross-agent collaboration is possible.** Multiple agents can write
to the same brain because the fence is the merge point, not the DB.
Git handles concurrent edits the way git handles concurrent edits.
## The three categories
Every table in the gbrain schema belongs to exactly one of three
categories. The category determines how it gets rebuilt during
disaster recovery.
### FS-canonical (markdown is the source of truth)
These are user-authored knowledge. The DB row is a derived index over
the markdown — wipe the table and `gbrain extract` rebuilds it
identically. The CI gate keeps direct DB writes from drifting away
from the markdown contract.
| Category | How it's stored in markdown | Derived DB table | Reconciler |
|---|---|---|---|
| **Takes** (incl. hunches, bets) | `## Takes` fenced table between `<!--- gbrain:takes:begin -->` / `:end -->` markers | `takes` | `extract takes` |
| **Facts** | `## Facts` fenced table between `<!--- gbrain:facts:begin -->` / `:end -->` markers | `facts` | `extract_facts` cycle phase |
| **Links** | Inline `[text](slug)` / `[[slug]]` in markdown body + frontmatter `direction: incoming` | `links` | `extract links` |
| **Timeline** | `## Timeline` section after `<!-- timeline -->` sentinel | `timeline_entries` | `extract timeline` |
| **Tags** | Frontmatter `tags:` YAML array | `tags` | `importFromFile` (reconciles per-page on import) |
| **emotional_weight** | Recomputed from takes + tags | `pages.emotional_weight` (signal column) | `recompute_emotional_weight` cycle phase |
| **synthesis_evidence** | FK into `takes` rows (`slug#N`) inside synthesis pages | `synthesis_evidence` | `extract takes` (transitively) |
### Derived from FS but not user-authored
These hold derived state that's automatically reconstructible from the
markdown but not directly authored as markdown by the user. The
chunker + embedder rebuild these on import.
| Table | Source | Notes |
|---|---|---|
| `pages` | The markdown file as a whole | One row per file; `compiled_truth` + `frontmatter` come from parse |
| `content_chunks` | `pages.compiled_truth` after chunker strip | Re-chunked on content_hash change; embedded via configured model |
| `page_versions` | Each `pages` UPDATE | Audit history; rebuildable in principle but not in practice |
### DB-only by design (named exceptions)
These hold runtime / infrastructure state that's intentionally not in
the repo. The architectural rule still holds — these aren't
"user knowledge" — but they're DB-only by design.
| Category | Why it's OK to be DB-only |
|---|---|
| `raw_data` | Webhook/transcript sidecars; not user-authored knowledge. |
| `subagent_messages` / `subagent_tool_executions` / `subagent_rate_leases` | Runtime job state. Replay-only, not persistent knowledge. |
| `oauth_clients` / `oauth_tokens` / `access_tokens` | Credentials. Not in source control by definition. |
| `mcp_request_log` | Audit trail. Volatile by design. |
| `minion_jobs` / `minion_inbox` / `minion_attachments` | Job queue. Restarts re-enqueue or drop. |
| `eval_candidates` / `eval_capture_failures` | Contributor-mode dev loop; opt-in capture. |
| `dream_verdicts` | Cheap verdict cache. Rebuildable by re-running Haiku. |
| `gbrain_cycle_locks` / migration ledger | Infrastructure. |
| `config` (some keys) | Site-local routing config (e.g. `sync.repo_path`). |
A new derived table that holds user-knowledge MUST land FS-first.
If you're tempted to add one as "DB-only for now," the structural
question is: does it belong in this DB-only-by-design list? If not,
it's FS-canonical and needs a fence (or frontmatter field) plus a
reconciler.
## The privacy boundary
Private knowledge in a fence still lives in the markdown file. If the
user commits the page to git, the private data lands in git too. This
is the existing operational model — we don't infer git policy.
For untrusted readers (remote MCP, subagent), the v0.32.2 release ships
a 3-layer strip:
1. **Layer A (chunker):** `src/core/chunkers/recursive.ts` calls
`stripFactsFence({keepVisibility: ['world']})` + `stripTakesFence`
before chunking. Private fact text never reaches
`content_chunks.chunk_text`, embeddings, or search results.
2. **Layer B (get_page):** when `ctx.remote === true`, the response
body has both fences stripped (private rows from facts; entire
takes fence). Local CLI (`ctx.remote === false`) sees the full
fence.
3. **Layer C (git tracking):** the user decides whether to commit the
entity page. `gbrain.yml` `db_only` paths are gitignored
automatically; per-page choices via the user's normal git workflow.
For universally-private entities (a friend's name, an investor's
internal notes), mark the entity page's directory as `db_only` in
`gbrain.yml`. The file stays on disk but never lands in git.
## The forget contract
`gbrain forget <id>` and the MCP `forget_fact` op rewrite the fence
row with strikethrough + `valid_until = today` + `context: "forgotten:
<reason>"`. The DB's `expired_at = valid_until + now()` derivation
reconstructs the forget state on every rebuild because the fence is
canonical.
Strikethrough has two semantics distinguished by context:
- `~~claim~~` + `context: "superseded by #N"` → row was replaced by
a newer row in the same fence
- `~~claim~~` + `context: "forgotten: <reason>"` → row was retracted
via the forget op
Both encodings keep the row in the markdown for audit history. To
permanently delete a fact, edit the fence directly in markdown and
remove the row. The next `extract_facts` cycle wipes the DB row.
## Disaster recovery
The promise the rule makes:
```bash
# Snapshot what's there
gbrain stats > /tmp/before.txt
# Wipe and rebuild
gbrain rebuild --confirm-destructive # v0.32.3 — deletes derived tables
# (pages + content_chunks survive
# the CASCADE-safe design)
# OR manually for v0.32.2:
psql -c 'DELETE FROM facts; DELETE FROM takes; DELETE FROM links; DELETE FROM timeline_entries;'
gbrain sync
gbrain extract all
# Counts match
gbrain stats > /tmp/after.txt
diff /tmp/before.txt /tmp/after.txt
```
The invariant E2E test at `test/e2e/system-of-record-invariant.test.ts`
exercises this exact flow on every CI run.
## Rule for new code
When you add a new user-knowledge category:
1. **Define the markdown shape.** Fence (`<!--- gbrain:NAME:begin
--> ... :end -->` table) or frontmatter field.
2. **Build a parser** that produces structured data from markdown.
See `src/core/fence-shared.ts` for the shared primitives.
3. **Build a writer** that round-trips: parse + edit + render produces
byte-identical markdown for identical input.
4. **Add the engine method** that takes parsed data and stamps a
derived table. The method gets an entry in the CI gate's
banned-direct-call list.
5. **Add a reconciler:** a cycle phase that walks pages, parses the
fence, and rebuilds the derived table from scratch. The reconciler
is the only legitimate call site for the engine method;
`// gbrain-allow-direct-insert: <reason>` annotates it explicitly.
6. **Add a round-trip test** in `test/e2e/system-of-record-invariant.test.ts`
that proves DELETE + reconcile rebuilds the table byte-identically.
The CI gate at `scripts/check-system-of-record.sh` fails any PR that
adds a new direct call to a derived-table writer outside the
reconciler / migration layer without the explicit allow-list comment.

# v0.32.2 CI guard: enforce the system-of-record invariant.
#
# The rule: user-knowledge writes to derived DB tables (facts, takes,
# links, timeline_entries) must go through the extract / reconcile /
# migration layer, never directly from arbitrary code paths. Direct
# calls would bypass the markdown source-of-truth contract — the next
# `gbrain rebuild` (v0.32.3) would lose the data because the fence
# wasn't updated.
#
# This script grep-bans the direct-write surface across src/ and
# scripts/ (NOT test/ — tests legitimately seed fixtures via direct
# inserts, per Codex R2-#8). A function-scoped allow-list lets the
# legitimate extract / reconcile / migration call sites pass: add

# v0.32.2 Migration: facts join the system-of-record
## What this is
v0.32.2 closes a gap that's existed since v0.31 shipped hot-memory facts.
Facts were DB-only — drop the `facts` table and the data was gone. v0.32.2
makes them FS-canonical: every fact write lands in a `## Facts` fence on
the entity page first, then stamps the DB index. The DB is now a true
derived cache for facts.
## What the agent needs to do
**For existing v0.31 brains (most users):**
1. Run `gbrain apply-migrations --yes` to invoke the v0_32_2 orchestrator.
2. The orchestrator runs in two phases:
- **phaseAFenceFacts** walks every legacy fact row (row_num IS NULL,
entity_slug IS NOT NULL) and appends it to the entity's markdown
fence atomically. Dry-run by default — runs in dry-run mode first,
reports what WOULD happen, then runs again with `--write` after
user confirms (or pass `--write` directly to skip the
confirmation step).
- **phaseBVerify** re-parses every touched fence + diffs against
the DB. Mismatch → marks the migration partial; user runs
`gbrain apply-migrations --force-retry 51`.
3. Refuses to run when any source's local_path has uncommitted git
changes. Mirrors the v0.14.1 `dry-fix` safety posture so the user
can review the diff before committing.
4. After completion: `git diff` shows the new fences; user can commit
them and the facts now live in git alongside the rest of the brain.
**For brand-new v0.32.2 installs (rare):**
The schema migration v51 creates the columns from the start (fresh-install
parity via the v40 CREATE TABLE block). The v0_32_2 orchestrator has
nothing to backfill (no legacy rows). It runs phaseA + phaseB and
no-ops cleanly.
**For thin-client installs (no sources.local_path):**
Facts continue to write to the DB directly with a once-per-process stderr
warning naming the missing `sources.local_path`. The architecture doc
names this as the explicit DB-only exception. To enable fence writes,
configure `local_path` via the source setup.
## Things that changed for the agent
1. **`gbrain forget <id>` now rewrites markdown.** Previously `gbrain
forget` called `engine.expireFact(id)` which UPDATEd the DB only.
After `gbrain rebuild` (v0.32.3) the forget would evaporate. v0.32.2
makes forget rewrite the fence: strikethrough the claim, set
`valid_until=today`, append `forgotten: <reason>` to the context
cell. New optional `--reason <text>` flag.
2. **MCP `get_page` strips private fact rows for remote callers.**
Previously the strip fired only when the caller carried a takes-
holders allow-list (a subagent privacy hole). v0.32.2 fires the
strip whenever `ctx.remote === true`. Local CLI sees the full
fence; subagent / remote MCP see world-only facts.
3. **The chunker strips private fact text.** `chunkText` calls
`stripFactsFence({keepVisibility:['world']})` alongside the
existing `stripTakesFence` before chunking. Private fact text
never reaches `content_chunks.chunk_text`, never gets embedded,
never returned by search.
4. **CI invariant gate.** `scripts/check-system-of-record.sh` is wired
into `bun run verify`. It bans direct calls to `engine.insertFact`,
`addLink`, `addLinksBatch`, `addTimelineEntry`, `upsertTake`,
`insertFacts`, `expireFact` in `src/` + `scripts/`. Legitimate
sites carry `// gbrain-allow-direct-insert: <reason>` comments on
the same line. New code that tries to bypass the reconcile layer
fails the build.
5. **New cycle phase `extract_facts`** runs between `extract` and
`recompute_emotional_weight`. Reconciles the DB facts index from
the fence on every affected entity page. Empty-fence guard refuses
to run while v0.31 legacy rows are pending the backfill (a belt to
the orchestrator's suspenders).
## Verification
After the agent runs the migration:
```bash
# Migration ran cleanly
gbrain apply-migrations --yes
# No fence write failures
test ! -f ~/.gbrain/facts.write_failures.jsonl || echo "WARN: some failures recorded"
# Each entity page with v0.31 facts now has a fence
ls people/ companies/ | head -5
grep -l 'gbrain:facts:begin' people/*.md | head -5
# Doctor passes
gbrain doctor
```
## Things to NOT do
- **Don't manually edit the v51 columns.** `row_num` and
`source_markdown_slug` are managed by the fence-write path. Edit the
markdown fence instead; the cycle phase reconciles.
- **Don't call `engine.insertFact` / `expireFact` from new code paths.**
The CI gate blocks it. If you genuinely need a direct write (e.g.,
for a new reconciler), add the `// gbrain-allow-direct-insert:
<reason>` comment with a justification.
- **Don't delete the `facts.write_failures.jsonl` log without
reading it.** It records pages where the fence parse-validate
failed during a write; the .tmp file remains as quarantine
evidence.

/**
* v0.32.2 migration orchestrator — facts join the system-of-record invariant.
*
* Schema migration v51 (src/core/migrate.ts) added the two fence columns
* (row_num, source_markdown_slug) and the partial UNIQUE index. The
* orchestrator's job is the data half: walk every existing pre-v51 row
* in the facts table (row_num IS NULL = "no fence yet") and append it
* to its entity page's `## Facts` fence, atomically + idempotently.
*
* Phases:
* A. Schema — assert migration v51 has run.
* B. Fence facts — backfill DB facts → entity-page fences (dry-run
* by default; explicit --write required).
* C. Verify — re-parse each touched page, count rows, compare
* against the DB rows for that page; partial on
* mismatch.
* D. Record — runner-owned ledger write (apply-migrations.ts).
*
* Idempotency: phase B only touches rows with row_num IS NULL. Re-runs
* after a partial completion pick up where the previous run stopped.
* Per-page atomic (.tmp + parse + rename, same primitive as
* fence-write.ts). Dirty-tree refusal mirrors src/core/dry-fix.ts so
* the user can review the diff before committing.
*
* Facts with NULL entity_slug are structurally unfenceable (no page to
* fence onto). They're skipped with a warning; the operator decides
* whether to hand-curate or delete them. Their row_num stays NULL
* forever; they live in the legacy keyspace permanently.

/**
* v0.32.2 — extract_facts cycle phase.
*
* Reconciles the facts DB index from the `## Facts` fence on each
* entity page. Runs between the `extract` phase (which materializes
* links + timeline) and `recompute_emotional_weight` so emotional
* weight sees fresh take + fact state.
*
* Source-of-truth contract: the fence is canonical. For each page in
* the affected slug set, this phase:
* 1. Reads the markdown body (DB-side fetch via engine.getPage).
* 2. Parses the `## Facts` fence with parseFactsFence.
* 3. Maps ParsedFact → FenceExtractedFact via extractFactsFromFenceText.
* 4. Wipes the page's DB index via deleteFactsForPage.
* 5. Re-inserts via engine.insertFacts batch.
*
* After the phase, the DB index for every affected page byte-matches
* the fence (modulo embeddings + runtime-derived fields). Pages with
* no fence go through delete-then-empty-insert — DB rows for that
* page coordinate are wiped; legacy NULL-source_markdown_slug rows
* survive because deleteFactsForPage targets source_markdown_slug =
* slug only.
*
* Empty-fence guard (Codex R2-#7): the phase refuses to do its
* destructive reconciliation pass when legacy rows (row_num IS NULL,
* entity_slug IS NOT NULL) still exist in the brain — they're the
* v0.31 hot-memory facts pending the v0_32_2 backfill. Status returns
* `warn` with a hint to run `gbrain apply-migrations --yes`. Without
* the guard, an interrupted upgrade where v0_32_2 hasn't run could
* leave the cycle silently misreporting "0 facts on people/alice"
* while legacy rows linger in the DB.

* v0.32.2: parser/renderer for fenced facts tables.
*
* The `## Facts` fence on an entity page is the system-of-record for facts
* about that entity. The `facts` DB table is a derived index reconciled by
* the new `extract_facts` cycle phase. This module is the boundary between
* the markdown and the DB.
*
* Structural mirror of `src/core/takes-fence.ts`. Same fence-shape
* primitives, same strict-canonical-lenient-hand-edit posture, same
* append-only row_num contract. Different column set:
*
* ## Facts
*
* <!--- gbrain:facts:begin -->
* | # | claim | kind | confidence | visibility | notability | valid_from | valid_until | source | context |
* |---|-------|------|------------|------------|------------|------------|-------------|--------|---------|
* | 1 | Founded Acme in 2017 | fact | 1.0 | world | high | 2017-01-01 | | linkedin | |
* | 2 | Prefers async over meetings | preference | 0.85 | private | medium | 2026-04-29 | | OH 2026-04-29 | |
* | 3 | ~~Will hit $10M ARR by Q4~~ | commitment | 0.55 | world | medium | 2026-06-01 | 2026-12-31 | bo call | superseded by #4 |
* | 4 | ~~Used to live in Tokyo~~ | fact | 0.9 | private | low | 2018-01-01 | 2026-05-10 | inferred | forgotten: user asked to remove |
* <!--- gbrain:facts:end -->
*
* 10 data columns + the leading `#` row-number column = 11 cells per row
* including the leading and trailing pipes.
*
* Strikethrough parse contract (resolves Codex R2-#3 forget-as-fence):
* - `~~claim~~` + `context: superseded by #N` → active=false, supersededBy=N
* - `~~claim~~` + `context: forgotten: <reason>` → active=false, forgotten=true
* - `~~claim~~` + anything else in context → active=false, both flags null
*
* The semantic layer (commit 3's `extract-from-fence.ts`) maps `forgotten`
* to `valid_until = today` so the DB's `expired_at` derives correctly via
* the existing `expired_at = valid_until + now()` rule.
*
* Both fences share row-level helpers via `./fence-shared.ts` — see that
* module for `parseRowCells`, `isSeparatorRow`, `stripStrikethrough`, and
* `escapeFenceCell`. Domain-specific parsing (column ordering, kind/
* visibility/notability enums, the strikethrough-context distinction)
* lives in this file.

/**
* v0.32.2: pure mapper from parsed-fence rows → NewFact rows ready for

* carry strings, optional flags, and the strikethrough-context semantic
* distinction. The engine layer (`engine.insertFact` / new
* `engine.insertFacts`) is Date-shaped and DB-shaped. This module is the
* boundary.
*
* It is intentionally pure: no engine call, no I/O. Inputs are the parsed
* facts plus the page-level binding (entity slug + source_id). Output is
* a `FenceExtractedFact[]` — structural superset of `NewFact` that
* carries the v51 fence columns (`row_num`, `source_markdown_slug`).
*
* Codex Q7 resolution: engines stay markdown-unaware. The cycle phase
* (commit 7) and the backstop rewrite (commit 5) call this function to
* convert parsed fences into engine-shaped rows, then hand them to the
* batch insert.
*
* Strikethrough → date derivation:
* - `forgotten` rows get `valid_until = today` so the DB's existing
* `expired_at = valid_until + now()` rule produces the same forget
* state after `gbrain rebuild` (v0.32.3) as before.
* - `supersededBy` rows preserve their existing `validUntil` if set;
* otherwise leave `valid_until = null` (the consolidator phase fills
* this in based on the newer row's `valid_from`).
* - Inactive rows with neither flag (parser-tolerated hand-edits) are
* treated like `forgotten` for DB-derivation purposes — the user's
* strikethrough intent is honored; the lost reason is a JSONL
* warning surfaced by extract-facts, not a parse failure.

/**
* v0.32.2 — markdown-first fact write path.
*
* The "system of record" invariant means new facts land in the entity
* page's `## Facts` fence FIRST, then the DB index gets stamped via
* engine.insertFacts. After this commit, every write path that wants
* persistent fact storage routes through `writeFactsToFence`. The DB
* single-row `engine.insertFact` stays in the surface for the
* legacy / thin-client fallback only (when the brain has no
* sources.local_path configured).
*
* Concurrency: reuses the v0.28 page-lock primitive
* (`src/core/page-lock.ts`), an FS-level lockfile under
* `~/.gbrain/page-locks/<sha256-of-slug>.lock` with PID-liveness +
* 5-minute TTL. Multi-process safe — two `gbrain` invocations writing
* to the same entity page serialize through the same kernel-visible
* lockfile. 5-second timeout per the plan's "5s retry" failure mode.
*
* Atomicity: write the fence to `<file>.tmp`, re-parse the .tmp body,
* THEN `renameSync` to the canonical file. If parse fails the .tmp
* stays in place as quarantine evidence and the JSONL surface
* (`facts.write_failures.jsonl`) records the failure for `gbrain
* doctor` to surface. The on-disk markdown file is never corrupted
* mid-write (renameSync is atomic on POSIX) and the DB is never
* inserted when the fence isn't valid (Codex Q7 atomic-write
* recovery).
*
* No re-entrancy needed: writeFactsToFence uses fs.writeFileSync +
* renameSync directly — NOT engine.putPage — so no code path can
* re-trigger runFactsBackstop on the markdown write. The architecture
* self-prevents the recursion concern Codex Q7 raised; documenting
* here so a future refactor that swaps writeFileSync for putPage
* sees the constraint.

/**
* v0.32.2 — forget-as-fence path (Codex R2-#3).
*
* Before v0.32.2 `gbrain forget` and the MCP `forget_fact` op called
* `engine.expireFact(id)` directly, which UPDATEs `facts.expired_at`
* in the DB. After `gbrain rebuild` (v0.32.3) that DB-only mutation
* would evaporate because the canonical markdown fence is unchanged
* — the forget would un-happen.
*
* The fix: forget becomes a fence rewrite. Strike through the target
* row's `claim` cell, set its `valid_until` to today, append
* `forgotten: <reason>` to its `context` cell. The DB's existing
* `expired_at = valid_until + now()` rule reconstructs the forget
* state on every rebuild because the fence is canonical.
*
* Strikethrough parse contract (extends commit 2's two-mode design):
* `~~claim~~` + `context: superseded by #N` → supersededBy=N
* `~~claim~~` + `context: forgotten: <reason>` → forgotten=true
* `~~claim~~` + anything else → active=false; the
* mapper treats this as forgotten for DB-derivation purposes.
*
* Two-tier fallback for cross-state safety:
* 1. If the target row has v51 columns (row_num + source_markdown_slug
* + sources.local_path), do the fence rewrite. The forget survives
* rebuild.
* 2. If any of those is missing (pre-v51 legacy row, NULL entity_slug,
* no local_path on the source), fall through to the legacy
* `engine.expireFact(id)` direct-DB path. A once-per-process
* stderr warning names the case so operators see the degraded
* mode. These forgets DO NOT survive rebuild — the architecture
* doc names this as the explicit DB-only exception for legacy
* / thin-client state.

/**
* v0.32.2 — system-of-record invariant E2E capstone.
*
* The architectural rule: the GitHub repo (markdown + frontmatter) is
* the system of record. The DB is a derived cache. We do not back it
* up — we rebuild it from the repo.
*
* This test proves the rule holds end-to-end. Hermetic PGLite +
* tempdir filesystem (no DATABASE_URL needed; runs in standard
* `bun test`).
*
* The capstone test:
* 1. Seed a fixture brain with markdown files exercising every
* category (facts at varied visibility, takes, timeline, inline
* links, mixed).
* 2. importFromFile every page; run extract phases.
* 3. Snapshot the derived tables (facts, takes, links,
* timeline_entries — NOT content_chunks since embeddings are
* non-deterministic).
* 4. DELETE the rebuildable derived tables.
* 5. Re-import every file (rebuilds tags via import reconciliation)
* + re-run the extract phases.
* 6. Snapshot again; diff. Assert row sets match.
*
* Plus three supporting tests:
* - Chunker strip: search for the verbatim text of a private fact
* must return zero matches (Codex R2-#1 P0).
* - get_page privacy strip: ctx.remote=true strips private rows
* from the response body (Codex R2-#5).
* - serializeMarkdown round-trip: page → import → DB state matches
* re-extract from re-rendered markdown (the canonical idempotency
* property that lets gbrain rebuild work).

*
* The page-lock contention test (multi-process integration via
* Bun.spawn) lives in test/e2e/facts-lock-contention.test.ts (commit
* 10's invariant E2E capstone, since spawning child processes is an
* E2E concern). These unit/integration cases cover the in-process

/**
* v0.32.2 commit 8 — 3-layer privacy strip + forget-as-fence tests.
*
* Three layers under test:
* - Layer A (chunker): chunkText strips private fact rows so private
* text never reaches content_chunks (Codex R2-#1 P0)
* - Layer B (get_page privacy trigger): stripFactsFence + stripTakesFence
* fire when ctx.remote === true (Codex R2-#5 closes the subagent hole)
* - Forget-as-fence: forgetFactInFence rewrites the fence row instead of
* the DB-only expire path so forgets survive gbrain rebuild (Codex R2-#3)
*
* Real PGLite + tempdir filesystem.
