* feat(native-chat): record which agent run wrote each journal item Each journal item row, subagent roster entry and background-task entry now records ownerFence: the lease fence of the agent run whose output produced it. Optional, persisted, no row version bump and no migration. The journal's itemFence() returns it, so the turn-verdict rules and per-run provider activity read the producing run rather than the writer's fence. * feat(native-chat): one current-work projection for every host reader; record death first The host decides what work is current in one place (structured-agent-session-current-work.ts) from the lease, the exit this host saw, the runtimes it replaced, its live child and each item's provenance. Every host reader (queue, Stop, prompt answers, commands, status feed, idle sweep, teardown snapshot, history pages and frames, orchestration mailbox) reads it, so a dead agent's leftovers stop reading Working or holding the queue even when their cleanup write failed. The journal's activeTurnId()/liveTurnScope() become the raw runningTurn(). On exit the host records the child's end first and signals generationEnded, which republishes frames, the status feed and settlement waits and wakes the queue drain with no journal row. Pages and frames carry optional working and actionablePromptIds fields. * feat(native-chat): clients read the host's working answer; refuse answers to a stopped agent plainly Desktop and mobile prefer the host's working and actionablePromptIds fields when present (merged across batches like latestTurn) and fall back to today's row derivation against an older host. A prompt an ended agent raised stops looking active; answering it is refused before any provider sees it, with "<Agent> has stopped, so your answer was not sent. Send a message to continue." Cancelling it only dismisses it in the journal: it no longer triggers the chat's Stop, pauses the queue or withdraws queued cards. * refactor(native-chat): keep structuredAgentSessionHandsOver file-local until a caller needs it Nothing outside the projection calls it in this part; Part 5 exports it for the start-failure row. * test(native-chat): fewer provenance tests: fold reopen and unstated-owner checks into the main case Drops the epoch-replacement case (Part 2 rewind test reads the same values through the same rebuild) and the corrupt-value case (no version writes one). * test(native-chat): drop current-work mirrors: the viewKey unit case and the still-live rewind case The flow cases keep every outcome: dead leftovers read as nothing, Stop has nothing to stop, a waiting card drains, a live owner publishes as before, and a rewind never promotes dead work. * test(native-chat): fewer client tests: one flow per client, one fallback each Keeps desktop and phone Working from the host (with the older-host fallback), the reducer merge contract, the ended question Cancel that only dismisses, the agent-named refusal and the resolution receipt. Drops per-helper prompt tests, the transcript-placement test, the stop-note client reduction, the Steer cards that match main, and per-reason refusal rows. * test(native-chat): an unstamped roster entry from an older build reads as its row provenance Moved here from Part 4 so it sits beside stampJournalEntryProvenance. * test(native-chat): build the older-build roster row inline, after main removed its body helper Main #27947 writes one row per subagent and deleted journal-subagent-group-body; a roster row from an older build is still what this case reads. * refactor(native-chat): provenance is per item only; drop per-entry stamping Main's #27947 writes one saved row per subagent, and each background task already has its own row, so an item's own ownerFence names the run of every entry a producer still writes. Per-entry stamps inside a row mattered only for the shared roster rows saved before #27947, and no run writes into those any more, so the row's own provenance settles them correctly. Removes the entry stamping, the optional ownerFence on roster entries and background tasks, and their tests. * fix(native-chat): an item's provenance is set when it is created; revisions keep it A newer run's provider can revise an item an older run created: Pi's start and an ACP session/load both report context usage onto the newest saved turn. Restamping that turn with the newer run let the newer run's exit settle the older run's unverifiable turn as interrupted. Only creation states an owner now, as main's itemFences rule did. * test(native-chat): keep the provenance test below the production lines it covers * fix(native-chat): an ended agent's card Cancel commits with its receipt, through dismissPrompt The ended-generation dismissal wrote the cancelled resolution without the Cancel's operation receipt and without the dismissal's failure handling, so a receipt write failing after it would answer "outcome unknown" over a card already closed. It now goes through dismissPrompt, which carries the uncommitted receipt in the same append and answers dismissalNotSaved on failure; a null `answer` skips the adapter, since no live provider holds an ended generation's card (Pi's adapter refuses a fence with no live session outright).
