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).

three blockers were real factual errors against the code, each verified directly
before folding: listPublished() is body-less (use runAssemble's inline
parsePublishedRecord loader); the core signature must be {recentPosts, records,
graph} (PostGraphNode has no body); the parser tracks the WRITER format
(state-updater.mjs:116), not pruneContentHistory's date-only :145 regex. Plus the
getStateFile() HOME-chain seam, logic-RED, single-literal gate decoys, recorded

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

Splits the old S3d charter: S3d = ops centre ONLY (operations.md becomes a
read tributary; strategy-advisor honours the dated frozen-past-self anchor
that deprecates older inferences — advisory/reader-side). The hygiene +
triple-post reconciliation half (dead content-history.md retirement +
post-tracking↔published↔analytics) moves to a new SB-S3e (the last S3 slice).
Light-Voyage hardening: scope-guardian ALIGNED (0 creep/gap); brief-reviewer
REVISE (5 FIX folded); plan-critic 3 major + 3 minor folded. Baselines
verified live: gate 95→97, brain 113→114, ASSERT floor 80→82. The RED-bearing
brain-test literal is pinned to the dated-anchor convention (_As of YYYY-MM-DD:_,
verified absent) — NOT 'deprecates older inferences', which already ships in
the seed comment and would make the RED gate vacuous.

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,

Hub-side design: thread specifics/trends ids onto the brain's published
record + a pure analytics resolver (title-prefix + date, confidence tiers).
Tributaries untouched; blast radius bounded to scripts/brain/. Answers the
north-star query "which raw material performs?" (specific -> post -> analytics).
Two hard constraints shaped the slice: profile.md's rigid 6-token grammar
keeps the fact->post link OUT (C-1, breaking SCHEMA_VERSION bump); analytics
has no body/URN so the analytics<->post join is a resolver, not a stored id (C-2).
Light-Voyage: brief-review APPROVE-WITH-FIXES (5 FIX), plan-critic

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).

Second sub-slice of SB-S3 (after S3a's reader landed). Adds an operator-gated,
explicitly-signalled supersede op to the consolidation engine: a temporal-update
candidate retires a stale fact (status: superseded, re-minted to an archival id,
replaced in place, retained as audit) and installs the new winner under the
canonical key-id. Bounded to scripts/brain/ — pure, deterministic, fully
unit-testable.
Operator-confirmed scope: temporal-update→supersede ONLY · winner→dynamic
(re-earn) · minimal `supersedes?: string` · retain superseded as audit.
Light-Voyage-hardened:
- brief-reviewer APPROVE-WITH-FIXES — 8 FIX folded (the load-bearing one: id
lifecycle → winner-takes-key-id, retired fact re-minted, so mintEntityId(key)
always points at the live fact).
- plan-critic REVISE → 2 BLOCK + 6 FIX folded: applyDiff must REPLACE-IN-PLACE
(not copy → would dup the canonical key-id); proposeDiff must value-guard the
supersede fork (a re-sent stale signal would self-supersede every run); plus
--gather active-only filter + decay excludes superseded (else retired facts
leak back as live context / spam stale flags).
- scope-guardian ALIGNED (0 creep / 0 gap).
Also reconciles brief-sb-s3a.md's stale DRAFT status (S3a landed 4fa411f).

The second brain now feeds generation: strategy-advisor reads brain/profile.md
as evidence-to-test (anti-sycophancy default, graceful absence on fresh installs).
First end-to-end proof of capture → consolidate → read-back-into-generation.
- agents/strategy-advisor.md: brain/profile.md added to Step 0 Load Context + a
consumption subsection (Static/Dynamic layers, evidence_count/last_seen weighting,
anti-sycophancy counter-pressure, silent degrade when the file is absent).
- scripts/test-runner.sh: new Section 16d (Brain Profile Reader) — 2 UNCONDITIONAL
checks (non-vacuity self-test with legacy-path/lowercase decoy + exact-literal
wiring grep on strategy-advisor.md), ASSERT_BASELINE_FLOOR 78→80, header
enumeration extended. Gate 93→95/0/0; brain floor 82 untouched.
- docs/second-brain/consolidation-loop.md: reconciled the stale "no reader yet"
honest-limit to the true partial state (one reader; broader consumption deferred).
TDD: RED (only the wiring grep failed, exit 1) → GREEN (95/0/0). READ-only — the
brain consolidate --apply --confirm gate stays the sole writer. SC4 (graceful
absence) verified by inspection; SC5 (read-back) deferred to a reloaded session
(honest — agent prompts load at session start). S3a scope held: one reader, no
parser, no id-threading.

No new test-runner section → ASSERT_BASELINE_FLOOR unchanged at 78 (the hook
SC6 test runs separately via `node --test hooks/scripts/__tests__/*.test.mjs`,
not the structure gate). Add docs/second-brain/consolidation-loop.md (CLI usage,

voice-trainer's Gather step now reads ingest/published/ (provenance=published) as

forbids learning from provenance=ai-draft, and fences the auto-append trap. New gate
Section 16c (Brain Published-Only Invariant) enforces the wiring with exact-literal

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.

Light-Voyage process artifacts for the first second-brain slice (SB-S0):
- brief.md — task brief, revised after adversarial brief-review (B1 fold-source
premise, B2 pathguard claim [later verified: STATE was right, reviewer wrong],
M1 floors-as->=, M2 scaffold trigger, M3 grammar contract, M4 runtime-only).
- plan-sb-s0.md — SB-S0 implementation plan, revised after adversarial
plan-review (plan-critic + scope-guardian, both code-verified):
B1 test convention -> real TS idiom (tests/*.test.ts via tsx, .js specifiers);
M2 profile format -> defined line-grammar (repo has no YAML parser, no dep);
M3 data-root -> inline per-package resolver (repo idiom, not a new seam);
M4 fold extraction rule pinned against the actual user-profile template;
+ minors (gate-count rationale, npm-install-before-gate, provenance throws,
stable-slug id, push-confirm).
scope-guardian: zero creep, zero MAJOR gap. plan-critic: B1+3 MAJOR, all folded.
Design phase, no code yet — awaiting operator go to build SB-S0 (TDD).

Persist the operator-approved second-brain architecture design and the three
parallel research threads that fed it, so nothing is lost before build:
- architecture.md — approved design: thin Markdown `brain/` hub (two-layer
profile.md + episodic journal/ + operations.md + index.md MOC) over the
existing typed tributaries (voice/specifics/trends/analytics), a
provenance-tagged ingest/ seam, a sleep-time consolidation loop with
evidence-threshold promotion + temporal-validity + anti-sycophancy/
anti-collapse invariants. Build sequence SB-S0..S4.
- research/connector-egress.md — LinkedIn data egress reality (EU/EEA DMA
portability API = auto for content; analytics manual CSV; no scraping).
- research/secondbrain-sota.md — 2026 second-brain / AI-memory SOTA synthesis.
- research/silo-inventory.md — faithful inventory of the 12 existing per-user
silos + the 5 hardest unification problems.
Boundary confirmed: engine -> plugin (domain-general), user data -> data dir,
cockpit -> Maskinrommet. Design phase, no code yet.
