 ### 5. Durable resources are reattachable by the same owner
 
+> **Proposed amendment (ADR 0024, 2026-09-14), `screen-recording` only.** Screen recording is a
+> *stop-and-collect* resource: its artifact is a file the native recorder finalizes on signal, and
+> its identity can only be re-proved at signal time. It keeps the persisted manifest, the
+> ownership fence on every destructive step, and the completed replay. It replaces the `reattach`
+> and `cleanup` facet operations with the backend's `stop(target, budget)` and `collect`, drops
+> `cleanup-pending` as a phase and the admission ledger for this kind, records the recorder
+> observation and the native-path disposition beside the committed export, and archives a
+> manifest by fence generation until both are settled.
+> For every durable kind, forced cleanup is no longer inferred from a failed finish once that
+> kind's failed-finish test states what its retry needs. App-log, audio-probe, and perf-capture
+> keep the contract below unchanged. Rationale, matrix, and tests live in ADR 0024.
