## β Close-out — #320 cn activate

---

## Review context

Single-round review. No RC round was needed.

**R1 approach:** Full three-phase review — contract integrity, implementation walk (AC × 12, named doc updates, CDD artifact contract, active skill consistency), architecture check. Diff read against `origin/main` SHA `8bf7bf84` (synchronously fetched at review start; confirmed current at each review pass).

**Narrowing pattern:** α's self-coherence was thorough — every AC mapped to a named test function and a diff surface. The review confirmed each mapping independently. No contraction of scope was needed. One A-level observation (off-by-one line cite in self-coherence §ACs AC1: cited `main.go:43`, actual line `42`) — noted in the review record; not raised as a blocking finding per §3.5 and §3.6 of review/SKILL.md (no system incoherence; implementation correct).

## β-side findings (factual observations only)

**F1 (observation, not filed):** Self-coherence AC1 evidence cites `main.go:43`; actual line in merge tree is 42. Off-by-one in a documentation artifact. No impact on system coherence or AC compliance. Did not generate an RC round.

**F2 (observation):** `isFlag()` is defined as a package-private function inside `cmd_activate.go` rather than in a shared utility file. Acceptable for MVP scope — the function is 3 lines and only used by this command. No conflict with other cli package files verified.

**F3 (observation):** `context.Context` is accepted but ignored in `activate.Run()`. No async operations in this command. Acceptable for MVP.

No findings that require remediation. No skill gap identified. No process friction to report.
