+Owner response to activity-core suggestion ff7d2152-75dd-4a49-8dac-e0ebe7343039
+(contest path for resolved decisions).
+
+Disposition: State Hub does not add a first-class `contested` decision state or
+a `/decisions/{id}/contest` route. State Hub is in retirement
+(`prj-state-hub-retirement`). Decisions are file-first work records whose
+writer convention is repo-manager (RMGR-WP-0008). The worked example was
+settled the same day by a superseding decision. The defect was that the hub
+never linked the two decisions. 1c9817ee (Activity Core owns the publisher)
+remained `resolved` with `superseded_by: null` after c6f23433 superseded it.
+The link was set by hand on 2026-10-13 with founder approval.
+
+The existing model already expresses re-assignment (`status: superseded`,
+`superseded_by`). This plan makes a missing link visible. It does not add a new
+authoring surface.
+
+## Add a consistency check for unlinked supersession
+
+```task
+id: STATE-WP-0097-T01
+status: todo
+priority: medium
+```
+
+Add C-43 (WARN, not auto-fixable) to `scripts/consistency_check.py`. It fires
+when a resolved decision's title or rationale cites another decision id with
+"supersedes"/"superseding" while that cited decision is still `resolved`, or
+has `superseded_by` unset or pointing elsewhere. Report both ids. The fix stays
+a deliberate founder/decider action: PATCH `status: superseded` and
+`superseded_by`. Add tests for the linked, unlinked and mismatched cases.
+Document C-43 in the checker header table.
+
+## Document the interim contest convention
+
+```task
+id: STATE-WP-0097-T02
+status: todo
+priority: low
+```
+
+Document the convention in `docs/`. An owner whose checked-in charter
+(INTENT.md, SCOPE.md, ADRs) excludes an assigned decision replies on the
+relaying thread with `CONTEST <decision_id>` and charter refs. Only the founder
+or the original decider re-resolves. Re-assignment is a new decision that
+supersedes the old one, followed by the link that C-43 checks. A first-class
+contest state is routed to the-custodian canon and repo-manager as the
+long-term owners. It is not built here.
