Writes OQ-42's five decisions into ADR format:
1. Storage: reuse the repo/adapter pattern (ADR-033, fourth instance
alongside IdentityProvider/IdentityStore/CredentialStore). New traits:
OwnershipProvider (sync read, hot-path) + OwnershipStore (async write,
handler lifecycle). In-memory default; persistence adapter additive.
2. Integration: AccessControl::check consults the ownership provider
directly (Option 2). OperationSpec gains resource_id_path (JSON pointer
into the input). Backward-compatible — ownership=None falls back to
the static Identity.resources path.
3. Access pattern: proxy-only. Spawner owns, proxy to share via from_call
+ forwarded_for (ADR-032), teardown revokes. No grant mechanism in
core. Future grant is additive (new trait method), stated as
reversal-cost classification, not deferral.
4. Four edge specifics: list = scope-gate + result-filter; teardown =
automatic, handler-driven; fleet = per-node ownership, downstream app
tracks 'who is this for'; composition = two orthogonal checks,
ADR-015/022 unchanged.
Reviewed: zero critical issues. Two warnings fixed (None-handling in the
check sketch, missing ADR-004 cross-ref). One suggestion applied
('v1 mechanism' → 'initial mechanism' to avoid hedging misread).
