 The store is intentionally separate from accepted registry graph snapshots. It
 keeps raw evidence runs, evidence items, and identity candidates available for
 inspection before any candidate is promoted.

+## Ownership Review
+
+To resolve ownership and containment from the normalized identities:
+
+```bash
+railiance-fabric discover-roots \
+  --ownership-review \
+  --store-db .railiance-fabric/accountability-evidence.sqlite3
+```
+
+The ownership review inherits owners from fabric/subfabric containment when
+possible, applies explicit owner evidence from discovery roots, and marks
+unresolved or ambiguous candidates as `needs_review`. Accepted candidates must
+have a resolved owner and containment unless they are actors or the netkingdom
+root.
+
+To persist a reviewer decision for a stable identity candidate:
+
+```bash
+railiance-fabric review-identity identity:repository:example-repo \
+  --store-db .railiance-fabric/accountability-evidence.sqlite3 \
+  --decision accept \
+  --owner-actor-id actor.railiance.primary-lord \
+  --fabric-id fabric.railiance.primary \
+  --reviewer operator \
+  --note "accepted from reviewed checkout evidence"
+```
+
+Reviewer decisions are keyed by stable identity key. Later rescans apply the
+latest decision for that key, so ordinary evidence refreshes do not lose
+reviewed ownership choices.

 - unresolved or ambiguous nodes are visible before promotion;
 - review decisions survive ordinary rescans.
 
+Result:
+
+- Added `schemas/accountability-ownership-review.schema.yaml` for ownership
+  resolution and review-blocker payloads.
+- Added `build_ownership_review()` to resolve explicit owners, inherit owners
+  from fabric/subfabric containment, flag unresolved ownership, flag unknown or
+  ambiguous containment, and surface ambiguous owner evidence.
+- Extended `AccountabilityEvidenceStore` with durable review decisions keyed by
+  stable identity candidate key.
+- Added `railiance-fabric discover-roots --ownership-review` and
+  `railiance-fabric review-identity` so operators can inspect blockers and
+  persist accept/needs-review/reject decisions across rescans.
+- Added tests proving ambiguous ownership is visible, review decisions can
+  accept a stable identity, decisions survive a later ownership-review run, and
+  accepted items cannot silently lack a resolved owner.
+- Documented ownership review and reviewer decisions in the manifest and
+  operator docs.
+- Verified with
+  `python3 -m pytest tests/test_accountability_roots.py tests/test_accountability_root_adapters.py -q`,
+  `python3 -m railiance_fabric.cli discover-roots --max-items-per-root 5 --ownership-review --store-db /tmp/railiance-root-ownership.sqlite3`,
+  and full `python3 -m pytest`.
