The LAST second-brain slice; the S0–S3e arc is now complete.
(b) Retire the dead, zero-reader content-history.md across its 8 plumbing
surfaces: the flaky Stop-hook writer prose, the template (git-rm'd), the
migrate-data.mjs B1 MOVE entry + its test assertions, .gitignore, the gate
SC2_CLASSES guard, the data-path ref-doc, and a session-start comment. SC1
grep = 0; migrate suite 5/5 (R8 idempotency demonstrated).
(c) `brain reconcile` — read-side triple-post reconciliation joining silo 1
(## Recent Posts, auto-tracked creation) to the silo 2↔3 graph, surfacing the
coverage gap: posts created via the plugin but never `brain ingest`-ed. New
pure core scripts/brain/src/reconcile.ts (parseRecentPosts tracks the WRITER
format state-updater.mjs:116, NOT the date-only pruner; reconcileRecentPosts
matches hook→record.body→graph for the in-graph/in-brain-only/orphaned tiers;
loadRecentPosts reads STATE_FILE via the canonical getStateFile() chain — a new
cross-seam read, the state file lives outside the brain dataRoot). Wired as the
`brain reconcile` CLI subcommand (inline parsePublishedRecord loader, not the
body-less listPublished). Read-only: never writes the state silo.
Tests (verified live): gate 99/0/0 (ASSERT floor 82→84; new Section 16f
self-test + CLI grep) · brain 127/127 (floor 114→127, +13 reconcile) · hook
suite 136/136. SC4/SC6 end-to-end run is a real behavioural pass (STATE_FILE
seam read + fallback). Honest limit: read-side cannot reconstruct un-captured
specifics/trends — auto-capture is the flagged follow-up.
Brief/plan: docs/second-brain/{brief,plan}-sb-s3e.md (fbad29d). Go-before-code
gate cleared (operator: retire · read-side · build-now).

Make brain/operations.md a READ tributary — the "operations centre" half of the
second brain. strategy-advisor now reads the dated "who I am now" anchor and
honours the frozen-past-self guard: when a profile.md fact predates or
contradicts the anchor, the anchor deprecates it (advisory/reader-side; NO
consolidate-engine change). Anti-sycophancy is INVERTED vs the profile —
profile facts stay evidence-to-TEST, the user-declared anchor is honoured.
- scaffold.ts operationsSeed(): dated-anchor convention (_As of YYYY-MM-DD:_) +
Plans/Ideas guidance; existence-skip idempotency preserved (no-clobber green).
- strategy-advisor.md: operations.md in Step 0 context-load + a consumption
contract (anchor authoritative, inversion, plans-vs-ideas, graceful absence).
- test-runner.sh Section 16e: 2 unconditional checks (non-vacuity self-test +
wiring grep, sibling-file decoy); ASSERT_BASELINE_FLOOR 80->82; BRAIN floor 113->114.
- architecture.md:80: build-row reconciled (S3d done; S3e = dead content-history
retirement + triple-post reconciliation = the new LAST S3 slice).
Gate 97/0/0; brain 114/114. TDD: RED proven (16e Check B + the scaffold
dated-anchor test both failed pre-fix) before GREEN. Splits the old S3d charter;
the hygiene half is deferred to SB-S3e. Light-Voyage hardened (scope-guardian
ALIGNED, brief-reviewer + plan-critic folds in docs 0061bf2).

Hub-side design: the published record now carries the specifics/trends ids
it was built from (additive, omit-empty → byte-backward-compatible), and a
new pure assembler (scripts/brain/src/assemble.ts + `brain assemble`) joins
post↔analytics by normalized title-prefix + date with honest confidence
tiers (high/low/none). Answers the arc's north-star query: which raw
material actually performs? (specific → post → measured analytics).
All four tributaries untouched (analytics READ-only via inlined raw-JSON,
no package import); profile.md grammar untouched (the fact→post link stays
OUT — C-1). The repeatable --specific/--trend ingest flags collect via a
new collectRepeated helper, leaving parseFlags untouched.
TDD: 19 new brain tests (ingest 4 + publish 3 + assemble 8 + cli 4), all
SC1–SC12. brain 113/113, gate 95/0/0, BRAIN_TESTS_FLOOR 94→113,
ASSERT_BASELINE_FLOOR unchanged at 80. Light-Voyage hardened
(brief-review 5 FIX · plan-critic 1 BLOCK+4 MAJOR+4 MINOR · scope-guardian ALIGNED).

The engine can now RETIRE a fact via an operator-gated, explicitly-signalled
temporal-update supersede — completing the consolidation motor's one S2 TODO
("no supersede in S2 — that's S3"). A `supersedes` signal on a candidate retires
the stale fact (re-minted to an archival id, status: superseded, REPLACED IN
PLACE, retained as audit) and installs the new winner under the canonical key-id,
so mintEntityId(key) always points at the live fact.
- consolidate.ts: Candidate.supersedes? + ProfileDiff.supersedes (SupersedeOp
carries the full winner fact, so applyDiff stays a pure projector). proposeDiff
value-guarded routing fork (routes only when the target holds a DIFFERENT value —
else a re-sent signal would self-supersede every run) + intra-batch
first-supersede-wins guard. applyDiff replace-in-place + value-matched state-check
(oldId present, active, value===oldValue) → idempotent re-apply + stale-diff safe;
superseded facts never bumped/promoted (supersede wins). Decay excludes superseded.
archivalId seeded with the pre-archival id (collision-free).
- cli.ts: renderDiffMd `## Supersessions (old → new)` (rendered last, only when
present → zero-supersession diffs stay byte-identical); validateCandidates optional
single-line `supersedes`; `--gather` profileFacts filtered to active (superseded
archival facts never re-presented as live context).
- Tests: +12 brain (consolidate 10 + consolidate-cli 2). TDD: RED (6 fail) → GREEN
(94/94). BRAIN_TESTS_FLOOR 82->94; ASSERT_BASELINE_FLOOR unchanged at 80 (no new
test-runner.sh section). Gate 95/0/0.
- Docs: consolidation-loop.md rule table + honest-limit reconciled (the operator
gate is the only classification net); engine docstring updated.
All 13 success criteria deterministically tested (unlike S3a, no behavioural-only
SC). READ-only gate unchanged — brain consolidate --apply --confirm stays the sole
profile.md writer. Scope held: scripts/brain/ only; temporal-update only
(condition-dependent/distractor deferred).

Operator-invoked, operator-gated loop:
- --gather reads published bodies directly (parsePublishedRecord, filtered by
published_date > last_run) + current profile, for the session to extract candidates.
- --propose validates candidates (shape + single-line key/value, else non-zero/no-write),
proposeDiff, writes brain/pending-diff.{json,md}; never touches profile.md.
- --apply --diff <json> --confirm is the ONLY path that writes profile.md (refuses
without --confirm), then records brain/consolidation-state.json last_run.
init/ingest/published preserved. 7 subprocess CLI tests (SC5). brain 75→82, tsc clean.

Add flag-routing infra (parseFlags) + two subcommands to the brain CLI, keeping
the existing `init` branch intact:
- `ingest --file <path> [--source] [--date]` / `ingest --scan-inbox` → capture
published posts into ingest/published/ (Wrote / Duplicate / Collision report).
- `published list [--json]` → inspect the gold corpus (id · provenance · date · first line).
6 subprocess tests incl. an explicit `init` regression guard. brain 57→63 tests, tsc clean.

Idempotent, collision-safe, create-on-demand IO under the brain dataRoot:
- writePublished: identical body → no-op; differing body at same id → disambiguated
<id>-N.md (never clobber, never silently drop a gold record, B2 defence-in-depth).
- ingestText: provenance always published; published_date defaults to captured_at.
- scanInbox: top-level *.md only (skips .DS_Store/dotfiles/non-md), non-destructive,
empty/absent inbox = clean no-op, re-scan re-skips via dedup.
- listPublished: parses each file in try/catch (malformed → skipped count, never
crashes), surfaces provenance so ai-draft leakage is eyeball-visible.
9 temp-dir IO tests. brain 48→57 tests, tsc clean.

SB-S0 (Foundation) of the second-brain arc: a new TS package scripts/brain/
(structural copy of specifics-bank) establishing the spine later slices hang on.
TDD throughout (failing test first); fold scope = P1+P2 only per operator decision.
- types.ts: one provenance vocab (human|published|ai-draft) + the six-field
ProfileFact record + two-layer ProfileDoc.
- id.ts: slugify + mintEntityId (sha256[:12], kind-namespaced, slug-keyed so the
id is stable across value edits) + normalizeProvenance (throws on unknown). [SC4]
- profile.ts: no-YAML line-grammar parse/serialize (parse∘serialize = identity over
the whole doc; values may contain ]/|/quotes) [SC2] + foldUserProfile: lossless,
idempotent, source-absent-aware fold of config/user-profile.template.md. Pinned
extraction — P1 labeled scalars (group-headers skipped, [placeholder]→empty) + P2
expertise group; stops at "### Research Tooling" so deferred explainer prose can't
leak in as fields. Checkbox-prefs (Goals/Tone/MCPs/Assets) deferred (§8). [SC3]
- dataRoot.ts: inline per-package resolver (repo idiom; no new seam → SC6).
- scaffold.ts/cli.ts: idempotent `brain init` — brain/{index,profile,operations}.md
+ journal/ + ingest/{inbox,published} under the data-dir; compare-then-skip, never
clobbers a user edit. No session-start wiring (SB-S2 owns it). [SC1]
Gate: new BRAIN floor in test-runner.sh (34 tests; trends/specifics/contract floors
unchanged) + anti-erosion floor 74→75. Full gate 90/0/0, tsc --noEmit clean. [SC5/SC6]
No new command/agent/reference → no version bump, no structure-count change.
