fix(agent-core-v2): clear the turn outcome when an undo rewinds it - #213
Merged
Conversation
…urn it describes
Undoing an interrupted turn left its outcome ('manually stopped', failed,
completed) visible in the activity view and in the persisted session
metadata. Clear the tracked outcome whenever an undo rewinds to or past
the turn it describes, keep it when only later turns are rewound, and
reconcile the persisted outcome against the replayed wire on restore.
📝 WalkthroughWalkthroughThe change clears stale turn outcomes when an interrupted turn is undone. Agent activity state, turn loop state, and persisted session outcomes now track turn IDs and reconcile undo and restore events. ChangesTurn Outcome Undo Handling
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The change is intended to clear turn outcomes when undo rewinds them, but a restored session can still retain and display a stale outcome, and the undo state handling may diverge from conversation history in some paths.

- Around line 142-154: Move lastEnded out of the turnKey state and into its own
state key chained with undoable(), removing the hand-rolled ContextUndo logic
from turnKey. Keep nextTurnId, cancelledTurnIds, and anchorTurnIds in the
world-time key, and preserve lastEnded’s undo/rollback behavior through the
standard undoable state handling.
In

- Around line 122-133: Update reconcileAfterRestore to normalize
lastEnded.reason and compare it with lastPersisted after the existing restore
guards; when the normalized reason differs, write the restored outcome with
touchUpdatedAt false, while preserving lastPersistedTurnId adoption and the
undefined-lastEnded handling. Add coverage in sessionOutcomeMirror.test.ts for
replacing stale persisted cancelled metadata with a restored completed outcome.

## Related Issue Follow-up to #213, from the review discussion on `reconcileAfterRestore`. ## Problem `SessionOutcomeMirror` persists the last turn outcome (`completed` / `failed` / `cancelled`) into the session metadata. On restore it only reconciled one stale case: a persisted outcome with no ended turn on the replayed wire. If the persisted value itself went stale — the async metadata write never landed before shutdown — a session whose last turn had actually completed still resumed showing "manually stopped" (or a failed badge), because the replayed wire had an ended turn and the reconcile kept whatever was on disk. ## What changed - `sessionOutcomeMirrorService.ts`: after restore, when the replayed `lastEnded` reason is unambiguous, adopt it with `touchUpdatedAt: false` and track its turn id for the undo range check: `completed` → `completed`, `failed` / `blocked` → `failed`. A replayed `cancelled` is deliberately left alone: the wire carries no `interruptReason`, so it cannot distinguish a user stop from a programmatic abort, and only user stops are ever persisted. - Tests: stale `cancelled` replaced by replayed `completed`; replayed `blocked` maps to `failed`; replayed `cancelled` keeps the persisted `completed`; the adopted turn id feeds the undo range check. ## Verification - `pnpm --filter @pymodel/agent-core-v2 exec vitest run` — 347 files, 5,723 tests passed - `typecheck`, `tsgo`, `lint:imports`, `check-no-comments`, oxlint on the changed files — all exit 0 ## Checklist - [x] I have read the [CONTRIBUTING](https://github.com/PyModel/pythinker-code/blob/main/CONTRIBUTING.md) document. - [x] I have linked a related issue (external PRs: the issue must have a maintainer's `/approve`). - [x] I have added tests that prove my feature works. - [x] Ran `gen-changesets` skill, or this PR needs no changeset. - [x] Ran `gen-docs` skill, or this PR needs no doc update.

No issue; maintainer fix found while reviewing undo behavior on the v2 engine.
Problem
After a turn was interrupted (or failed / completed) and the user then undid that turn, the "manually stopped" outcome stayed visible in the activity view and was still persisted in the session metadata. Undo rewound the context, but nothing cleared the outcome that described the rewound turn, so clients kept showing a stale state.
What changed
turnOps.ts: theContextUndoreducer now clearslastEndedwhen the undo rewinds to or past the turn it describes; it keeps the outcome when only later turns are rewound.activityViewService.ts: subscribes toContextUndoneand dropslastTurnwhen the undone range covers it, so the activity view republishes without the stale outcome.sessionOutcomeMirrorService.ts: tracks the turn id behind the persisted outcome, clears it onContextUndonewhen that turn was rewound (including when the undo outruns the tracked anchors), and reconciles the persisted outcome against the replayed wire on restore so a session resumed after an undo does not revive it.Verification
