Description

Objective

Integrate the completed, pushed, immutable implement-crash-safe candidate commit 23f05b26ebb170834ac0c6da004b1f76c1095dbb onto current main without re-running or replacing its substantive implementation. Preserve the original failed-attempt ledger as evidence; this is a recovery/integration task for a bootstrapping handoff failure.

Evidence and boundary

Original branch/ref: wg/agent-898/implement-crash-safe / origin/wg/agent-898/implement-crash-safe.
Both agent-898 and exact-session continuation agent-912 recorded completion-accepted; focused tests and installed-binary owned smoke passed.
Both terminal attempts were then mislabeled Lost because their generated wrappers came from a pre-candidate daemon and lacked the candidate-added post-exit wg finalize settle call. Do not interpret this as source failure.
Do not mutate/delete the retained worktree, Pi session, bootstrap archive, logs, or commit. Do not squash away provenance.
Main has advanced since candidate base dd3b489a; git merge-tree --write-tree main 23f05b26 currently reports one textual conflict in tests/smoke/manifest.toml, with other overlaps auto-merging. Treat all overlaps as requiring semantic inspection, not blind acceptance.

Requirements

In the isolated recovery worktree, merge the exact candidate commit/history into the then-current main, retaining all later main functionality.
Resolve the smoke manifest add/add/list conflict by preserving every current scenario/owner plus candidate_finalization_transaction; do not discard the concurrent worksgood promotion.
Review auto-merged lifecycle, Pi watchdog, spawn/wrapper, CLI, service, and main/lib integration for semantic drift from intervening commits.
Keep evaluation/FLIP/global gate policy disabled; this task performs deterministic integration validation only.
Commit and push the integrated result through normal WG completion. Log the resulting integration commit on implement-crash-safe; do not falsify or erase its two historical Lost events.

Validation

Exact candidate commit is an ancestor of the recovery branch result and its source files/tests are present; only conflict-resolution changes are introduced beyond candidate+current-main histories.
candidate_finalization_transaction remains registered exactly once with owner implement-crash-safe and its installed-binary smoke passes.
Focused candidate-finalization, lifecycle, Pi watchdog, worktree observer, spawn preparation/recovery, waiting resume, and rate-limit telemetry tests/smokes pass against the integrated tree.
cargo fmt --check, cargo clippy, cargo build --locked, and the bounded full test suite pass or preserve only independently proven pre-existing failures with exact evidence.
No retained evidence/worktree/session cleanup occurs before main integration is durable.
Commit/push and wg done complete through the normal recovery-task candidate path.

## Objective
Integrate the completed, pushed, immutable `implement-crash-safe` candidate commit `23f05b26ebb170834ac0c6da004b1f76c1095dbb` onto current main without re-running or replacing its substantive implementation. Preserve the original failed-attempt ledger as evidence; this is a recovery/integration task for a bootstrapping handoff failure.

## Evidence and boundary
- Original branch/ref: `wg/agent-898/implement-crash-safe` / `origin/wg/agent-898/implement-crash-safe`.
- Both agent-898 and exact-session continuation agent-912 recorded `completion-accepted`; focused tests and installed-binary owned smoke passed.
- Both terminal attempts were then mislabeled Lost because their generated wrappers came from a pre-candidate daemon and lacked the candidate-added post-exit `wg finalize settle` call. Do not interpret this as source failure.
- Do not mutate/delete the retained worktree, Pi session, bootstrap archive, logs, or commit. Do not squash away provenance.
- Main has advanced since candidate base `dd3b489a`; `git merge-tree --write-tree main 23f05b26` currently reports one textual conflict in `tests/smoke/manifest.toml`, with other overlaps auto-merging. Treat all overlaps as requiring semantic inspection, not blind acceptance.

## Requirements
- In the isolated recovery worktree, merge the exact candidate commit/history into the then-current main, retaining all later main functionality.
- Resolve the smoke manifest add/add/list conflict by preserving every current scenario/owner plus `candidate_finalization_transaction`; do not discard the concurrent `worksgood` promotion.
- Review auto-merged lifecycle, Pi watchdog, spawn/wrapper, CLI, service, and main/lib integration for semantic drift from intervening commits.
- Keep evaluation/FLIP/global gate policy disabled; this task performs deterministic integration validation only.
- Commit and push the integrated result through normal WG completion. Log the resulting integration commit on `implement-crash-safe`; do not falsify or erase its two historical Lost events.

## Validation
- [ ] Exact candidate commit is an ancestor of the recovery branch result and its source files/tests are present; only conflict-resolution changes are introduced beyond candidate+current-main histories.
- [ ] `candidate_finalization_transaction` remains registered exactly once with owner `implement-crash-safe` and its installed-binary smoke passes.
- [ ] Focused candidate-finalization, lifecycle, Pi watchdog, worktree observer, spawn preparation/recovery, waiting resume, and rate-limit telemetry tests/smokes pass against the integrated tree.
- [ ] `cargo fmt --check`, `cargo clippy`, `cargo build --locked`, and the bounded full test suite pass or preserve only independently proven pre-existing failures with exact evidence.
- [ ] No retained evidence/worktree/session cleanup occurs before main integration is durable.
- [ ] Commit/push and `wg done` complete through the normal recovery-task candidate path.

2026-07-27T17:04:54.119727126+00:00 Task paused
2026-07-27T17:04:54.203791863+00:00 Task published
2026-07-27T17:44:17.773069567+00:00 Spawn preparation deferred before launch permit; rollback is complete and no circuit-breaker charge was recorded. Repair the reported checkout/configuration condition and retry: spawn transaction for agent-918 rolled back (task remains dispatchable; rollback diagnostics: complete): failed to establish isolated-worktree observer baseline: observer state already exists; use open_at for restart reconciliation
2026-07-27T17:45:12.910779348+00:00 Spawned by coordinator --executor pi --model openai-codex:gpt-5.6-sol --isolation required-worktree
2026-07-27T17:45:28.145489497+00:00 Starting recovery: inspect current branch, exact candidate ancestry, merge conflicts, and semantic overlaps before deterministic validation.
2026-07-27T17:45:37.394226956+00:00 FANOUT_DECISION: stay inline — exact-history merge, one manifest conflict, semantic overlap review, and validation are sequential in the same integration tree.
2026-07-27T17:47:00.150792743+00:00 Merged exact candidate history with --no-ff/--no-commit. Resolved sole manifest conflict grow-only: retained all current entries including worksgood_concierge and added candidate_finalization_transaction exactly once. Reviewing auto-merged lifecycle/watchdog/spawn/service/CLI seams.
2026-07-27T17:51:35.692653225+00:00 Semantic overlap review: candidate additions remain adjacent to and compile with concurrent rate-limit telemetry, waiting-resume, observer/TUI, worksgood promotion, and dispatch changes. cargo fmt --check, cargo build --locked, cargo clippy --locked, and all 5 candidate integration tests pass.
2026-07-27T18:01:14.580494213+00:00 Focused integration validation passes: installed candidate finalization transaction; Pi watchdog human flow; isolated worktree observer; spawn preparation/recovery; waiting resume. Unit/integration: candidate 5/5, lifecycle 22, Pi watchdog 13, observer 13, waiting 2, telemetry 5, rate-limit 5. Worker-control env was explicitly removed from in-process test binaries to avoid treating fixture IDs as this live Pi task.
2026-07-27T18:01:39.929752791+00:00 Integration commit: 90fd288a — pushed to origin/wg/agent-918/recover-implement-crash-safe-candidate; exact 23f05b26 candidate is second parent/ancestor. Only manual resolution was grow-only tests/smoke/manifest.toml.
2026-07-27T18:05:03.846286203+00:00 Bounded full serial suite (worker-control env removed): 3024 lib tests pass, then bin suite 3844 pass / 11 fail. Failures exactly match independently logged current-main baseline from promote-worksgood-default-install: 7 stale add route tests, 3 stale recover route/endpoint tests, 1 observer concurrency test (observer state already exists). Full log: /tmp/recover-full-test.log. Candidate/focused suites all green.
2026-07-27T18:05:30.204374723+00:00 Final validation: HEAD 90fd288a equals pushed upstream; exact candidate 23f05b26 is ancestor/second parent; required source/tests present; manifest parses and candidate scenario is exactly once with owner implement-crash-safe; worksgood promotion scenarios retained. cargo fmt --check, cargo clippy --locked, cargo build --locked, cargo install --path . --locked pass. Focused tests/smokes green; bounded full suite preserves only the independently proven 11 current-main baseline failures.
2026-07-27T18:06:06.668546515+00:00 Reconciliation recorded one fenced lost attempt; explicit retry is required
2026-07-27T20:46:52.166085171+00:00 Task reset for retry from failed (attempt #2) — reason: Operator acceptance after durable fast-forward of validated integration commit 90fd288a onto main; prior Lost event was a pre-finalizer wrapper handoff failure, not source failure
2026-07-27T20:46:52.224922136+00:00 Task claimed by @operator-recovery
2026-07-27T20:46:52.276330938+00:00 Operator closeout: main and origin/main are 90fd288a; exact candidate 23f05b26 is second parent/ancestor; validated recovery branch was fast-forwarded without changing bytes. Historical Lost attempt retained.
2026-07-27T20:46:52.352631793+00:00 Task marked as done
