# OKF second-brain convergence — coordination log

> Cross-repo coordination for the OKF-compatible second-brain form (`spec.md`). This is the **one
> shared place** all three plugin sessions read to know where the others are. OKF reserves `log.md`
> for change logs; this extends it with rollout status + the coordination protocol.
>
> **No writing crosses repo boundaries** — each plugin session writes only its own repo (+ the catalog
> with its own go). Status here is updated via operator relay.

## Coordination protocol

The operator runs one Claude session per plugin repo and relays between them. To keep three
independent sessions converged **without** cross-repo writes (mirrors the maskinrommet feedback-register
pattern):

1. **Single source of truth = `spec.md`.** The convention is defined once, here. No plugin redefines it
   locally; a plugin's local OKF doc *references* this file. (Mirrors the global rule: don't invent
   local mechanisms; extend the shared one.)
2. **This log is the cross-repo state.** Convention version, decisions, per-plugin conformance status,
   open coordination items. All three sessions read it.
3. **No writing crosses repo boundaries.** Each session writes only its own repo. The catalog is shared
   but needs a per-session go. A plugin records its own conformance in its own STATE/changelog; the
   operator relays it here.
4. **Operator = relay + truth-source.** Convention changes are proposed by any session, written here
   (with go), and the operator carries "convention changed → re-check conformance" to the other
   sessions.
5. **Two version markers** (spec §12): `okf_version` (upstream Google OKF) and this convention's own
   version. Either bump → log it below → each plugin re-checks.
6. **Conformance is verified, not asserted.** A plugin's status only moves to 🟢 after its bundle passes
   the shared acceptance gate `catalog/scripts/okf-check.mjs` (spec §7) — `node catalog/scripts/okf-check.mjs <bundle-root>` → exit 0. On a relayed conformance landing, run the gate against that
   plugin's bundle and record the result here. Evidence-based flips only (operator verification-plikt).

## Per-plugin conformance status

Legend: 🔵 not started · 🟡 building / partial · 🟢 conformant (+ commit-ref). **Ratification**
(spec accepted + plan adapted) is recorded in the Status cell with the plugin's own commit-ref —
distinct from conformance (code landed), which `linkedin-studio` alone holds so far.

| Plugin | Against minimal contract (spec §3) | Notes | Status |
|---|---|---|---|
| **linkedin-studio** | `type` + per-level `index.md` + root `okf_version` on `brain/`; `ingest/` excluded (round-trip-critical tributary) | Reference design. Emits frontmatter, adds no parser. Brain suite 134/134; passes the **shared gate** `catalog/scripts/okf-check.mjs` (scaffolded `brain/` → "OK: valid OKF bundle", exit 0) — same verdict as okr's reference checker. | 🟢 conformant @ linkedin-studio `da0a16a` (2026-06-26) |
| **okr** | `type` required + recommended-as-warnings + `okf_version` echo | Has the reference **writer + checker** (`okf-check.mjs`, `okf-index.mjs`, `lib/frontmatter.mjs`) + skill `okr-second-brain-search` v1.6.1. | 🟡 built · **spec ratified @ okr `75bfc9b` (2026-06-29)**; conformance-alignment landing = own go |
| **ms-ai-architect** | designed, not built | Targets the fuller OKF package + a retrieval skill. Builds against this spec. | 🔵 designed · **spec ratified @ ms-ai-architect `72a7e2b` (2026-06-29)**; build = own go |

## Landing protocol — how a sibling records conformance

When your plugin's bundle actually conforms (the work of step 4, done in your own session):

1. **Record it in your own repo** (STATE/changelog) — as the handoff already instructs.
2. **Update THIS file** (your own catalog-go): set your row in the status table above to
   🟡 → **"claims conformant @ `<commit>`, bundle `<path>`, awaiting gate-verification"**.
3. A **linkedin-studio session** then runs the shared gate against your bundle —
   `node catalog/scripts/okf-check.mjs <path>` — and, on exit 0, flips your row to 🟢 with the proof.

This puts the landing signal in the **one shared doc**, so the operator need not hand-carry status, and
any session sees the truth on its next read. **Honest limit:** there is no live push-notification across
separate sessions — a landing is discovered when a session next *reads* this log (a linkedin-studio
session is told to check it at start; see its STATE). Self-flipping straight to 🟢 is **not** the
protocol; 🟢 is reserved for the independent gate-verified step (operator verification-plikt).

## Open coordination items (what each session must confirm)

> **✅ Resolved 2026-06-29 — both siblings ratified.** okr (`75bfc9b`) and ms-ai-architect (`72a7e2b`)
> ratified `spec.md` and adapted their plans. The items below are **accepted via ratification**; they
> are kept as the record of what was asked. Any new field-gap, change-proposal, or conformance landing
> arrives as a **fresh item / status bump**, not here.

**→ okr session:**
- Confirm `okf-check.mjs` semantics are stable enough to stand as the reference contract (spec §3, §7),
  and that this spec faithfully generalizes them (only-`type`-required; recommended → warnings;
  `okf_version` echo).
- Canonical recommended-field name is **`resource`** (OKF), not `source` — confirm okr uses `resource`.
- Flag any field okr needs that the minimal contract + recommended set doesn't cover.

**→ ms-ai-architect session:**
- Confirm the minimal contract + extension-key model (spec §3, §5) supports the planned **"full OKF
  package"** KB structure — going fuller is fine; the minimal contract is the **floor, not the ceiling**.
- **Field-name drift:** the architect brief writes `source`/`timestamp` (line 45); canonical is OKF's
  **`resource`**. Align on `resource`.
- **mdcode is not an OKF tool** (spec §9.1) — drop it from the adoption plan. The `reference_agent`
  enrichment is GCP/Gemini-bound (spec §9.2) — adopt the *prompt patterns*, not as drop-in code.

**→ both:**
- Ratify `spec.md` as the shared contract, or propose changes here.
- Retrieval-skill naming/home: okr shipped `okr-second-brain-search`; architect plans
  `second-brain-search`. If a shared skill ever happens (Stage 3), converge naming + home (standalone
  plugin, spec §11) — **not now** (Stage 2 measurement must justify it first).

## Change log

- **2026-06-29** — Convention **v0.1** authored (`spec.md`) + this log. Seeded from the three per-plugin
  design notes + linkedin-studio's verified premise corrections (mdcode ≠ OKF tool; no reusable OKF
  ingest code; classify/convert is build-yourself). linkedin-studio recorded **🟢** (brain emits
  OKF-compatible form, cross-tool-verified against okr's `okf-check`). okr / ms-ai-architect rollout =
  separate per-repo go. _(Authored by the linkedin-studio session; operator relay to siblings pending.)_
- **2026-06-29** — **Stage 1 ratification complete across all three tracks.** okr ratified spec v0.1 +
  adapted plan @ okr `75bfc9b`; ms-ai-architect ratified spec v0.1 + adapted plan @ ms-ai-architect
  `72a7e2b` (both relayed via operator). The shared contract is now accepted by all three — the
  interop goal of Stage 1 is met at the convention level. Conformance *landings* (okr form-alignment,
  ms-ai-architect build) remain each their own go. _(linkedin-studio session, operator relay.)_
- **2026-06-29** — **Shared acceptance gate landed** (`catalog/scripts/okf-check.mjs` +
  `okf-frontmatter.mjs` + `okf-check.test.mjs`). Lifted faithfully from okr's reference impl; verdict
  logic byte-identical, English output, zero deps, self-contained. Verified: 33/33 catalog tests green;
  verdict parity with okr's checker on okr fixtures (positive + negative); a scaffolded linkedin-studio
  `brain/` validates clean (exit 0). Wired as the conformance gate (protocol §6 + spec §7): a plugin
  only moves to 🟢 after passing it. The only Stage-3 remainder is reconciling the TS/mjs impls — not
  required for the gate. _(linkedin-studio session.)_
