Production failure shape:
Auto-recovery failed: branch conflict unrecoverable \u2014
Branch fusion/fn-4847 is already checked out at /.../deft-crane
(tip a881ccc86660, 24 stranded commits since 0b28388876).
Run branch recovery and explicitly choose whether to reclaim or
discard prior work.
The 24 stranded commits are cross-task contamination residue from the
FN-4781/FN-4804/FN-4814 worktree-race era \u2014 they are NOT FN-4847's work.
Previously this paused the task with pausedReason='branch-conflict-
unrecoverable' and the task got stuck forever waiting for human
adjudication.
User intent (FN-4847): 'just create a new branch and keep going and
discard the old one'. Implementation:
1. auto-recovery.ts:actionForMode \u2014 in 'deterministic-only' mode (the
default), branch-conflict-unrecoverable now returns 'retry' (was
'pause'). This routes the failure to the handler instead of pausing.
2. auto-recovery-handlers/branch-worktree.ts \u2014 'live-foreign' inspection
no longer emits irreducible-pause. Instead:
- Check FN-4811 active-session registry. If the foreign worktree is
bound to a live executor/merger session, do NOT force-remove it
(would yank the live agent's filesystem). Just requeue and let
downstream conflict-recovery handle it.
- Otherwise: force-delete the foreign worktree (--force) + prune git
worktree admin entries + force-delete the branch. Errors at each
step are best-effort and logged.
- Emit new audit event 'branch-worktree:foreign-branch-discarded'
with stranded-commit count, live-ownership flag, success flags.
- Requeue task to 'todo' with preserveProgress, clearing
branch+baseCommitSha.
3. run-audit.ts \u2014 register new DatabaseMutationType.
4. executor-worktree.test.ts \u2014 update the 'records recovery context'
test to assert the new retry+requeue contract (was asserting the old
pause-with-status-failed contract).
Verification:
- Targeted suite (4 files, 343 tests): pass.
- pnpm --filter @fusion/engine build: clean.
- pnpm lint: clean.

- Add node settings sync round-trip tests covering outbound push and pull flows
- Assert outbound node sync and auth routes send the target node Bearer apiKey
- Reject inbound requests authenticated with a remote node key and outbound requests targeting the local or missing node
- Verify auth-sync diagnostics stay redacted and do not leak credentials
Fusion-Task-Id: FN-4833
Refactors the settings store tests in `packages/core` by consolidating round-trip and default value coverage into structured `it.each` matrices, trimming the test file by roughly 60 lines while maintaining equivalent coverage.
Fusion-Task-Id: FN-4836
Hardens test timeouts across 12 reliability and integration test files (branch-conflict recovery, merger diff/overlap guards, self-healing, worktree hydration, workflow/file-scope interactions), covering both real-git and mock-based test lanes with consistent timeout adjustments to reduce flakiness.
