+## v0.2+ stream sequencing (post-v0.1.0, decided 2026-07-06)
+
+v0.1.0 is tagged — the format-agnostic text core (modules 1–11, hardened at
+`5397ba1`, released at `df30c7b`). Three forward streams, **all to be built**;
+the order is dependency-driven, not preference:
+
+1. **OKF v0.2 hardening** — the OKF adapter + the 8 tasks in
+   `docs/OKF-INGESTION-BRIEF.md` §8 (internal order T8 → T1–T4+T6 → T7 → T5).
+2. **Wire consumers** — `claude-code-llm-wiki`, `ms-ai-architect`,
+   `portfolio-optimiser` (its OKF-upload-inbox is the flagship).
+3. **Node/polyglot port** — one polyglot repo over the shared JSON lexicon
+   (BRIEF §13.5/§8); driver = `ms-ai-architect` convergence.
+
+**Why this order (dependencies, not taste):**
+
+- The flagship consumer (`portfolio-optimiser`'s OKF-upload-inbox) *is* an OKF
+  surface. Wiring it before OKF hardening ships a knowingly-incomplete guard
+  into the exact case that needs it → **stream 2 depends on stream 1**.
+- The Node port must port a *settled* public surface. OKF v0.2 adds the
+  OKF-adapter surface; porting before it = porting a moving target and exactly
+  the §13.3 split-drift the polyglot rule exists to forbid → **stream 3 after 1**.
+- Within stream 1: **T8** (residual-risk docs, brief §7.2/§7.4) is the cheap,
+  decision-free first step — it lands independently and makes the live README
+  honest about uncovered OKF surfaces before anything else is built. **T3/T4/T5
+  are blocked on an OKF-spec confirmation pass** (brief §9 "operator premise":
+  concept-ID=path-minus-`.md`, reserved `index.md`/`log.md`, the `resource`
+  field, `description`→`index.md` were taken from the brief, not checked against
+  `SPEC.md`).
+
+**Splittable early win (optional):** text-only consumers can be wired at v0.1.0
+today — for them the guard is already complete. Folded behind stream 1 by
+default (editing other repos = context switch + weaker feedback than the
+flagship). Pull forward only on explicit request.
