- review-003: frontmatter flipped open -> closed with the acceptance
record (ADR-020 accepted 2026-10-18, commit eea472b; OQ-20 resolved
by it — the §Decision 2 re-entry door this review's disposition
named to open). In-body closure annotations on the Addressing
conversation and Disposition sections: the ask table is fully
dispositioned (F-1..F-4 inside ADR-020), the implementation wave is
the remaining work and gates on nothing here.
- overview.md: the keying story aligned to the registry posture —
"one canonical content hash" was the pre-ADR-018/020 shape; the
registry of git-family derivations with no default put (ADR-020's
invariant) is what this crate is now. The alkgit bullet cites the
ADR-018 extension. Spec stays `stable` (wording alignment to decided
ADRs, no shape change).
Verification: docs-only; link depths checked (docs/reviews ->
../architecture/...), confusable-character sweep clean.
