Completes the linkedin-studio in-scope Stage 1 (docs/okf-convergence-brief.md):
- serializeProfile + operations.md seed gain the cheap recommended OKF fields
`title` + `description` (timestamp/resource intentionally omitted — a timestamp
would break the pure/deterministic serializer; resource is N/A internally).
- renderDiffMd leads the transient pending-diff.md with `type: PendingDiff`, so
the brain/ bundle passes okf-check even mid-propose.
Verified: 2 new tests (okf-conform + consolidate-cli); full brain suite 134/134
(0 regressions); cross-tool — okr/scripts/okf-check.mjs validates brain/ exit 0
WITH a pending-diff present.

Cross-plugin OKF convergence, Stage 1 (docs/okf-convergence-brief.md): the
second-brain hub now conforms to OKF-compatible form so a shared retrieval
skill (and a sibling agent) can traverse it.
- serializeProfile leads with a constant `type: Profile` frontmatter block
(round-trip-safe: parseProfile skips it, parse-serialize identity holds).
- operations.md seed -> `type: Operations`; index.md seed -> `okf_version: 0.1`
marker (markdown text; index files carry no frontmatter per OKF); new
brain/journal/index.md (per-level index).
Premise correction: the brain is deliberately YAML-free and ingest/published
has a byte-exact round-trip invariant (SC2) a frontmatter block would break,
so the concept-bundle is scoped to brain/ ONLY; the ingest/ tributary is
excluded and pointed to from the hub. We emit frontmatter, add no parser.
Verified: new tests/okf-conform.test.ts (5/5); full brain suite 132/132 (0
regressions); cross-tool — okr/scripts/okf-check.mjs validates brain/ (exit 0).

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).

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.
