# Complete - m-iop-owned-single-request-agent-execution/14+05,12,13_observation_timing

## Completion Time

2026-08-07

## Summary

Completed raw-free single-request lifecycle observation and deadline ownership across five reviewed loops; final verdict PASS.

## Loop History

| Plan | Review | Verdict | Notes |
|------|--------|---------|-------|
| `plan_cloud_G07_0.log` | `code_review_cloud_G08_0.log` | NOT REVIEWED | Initial workspace-observation pair was superseded before implementation evidence or a verdict. |
| `plan_local_G06_1.log` | `code_review_cloud_G07_1.log` | FAIL | R1-R3 required production observer wiring, semantic lifecycle timing, and real lifecycle integration coverage. |
| `plan_cloud_G07_2.log` | `code_review_cloud_G07_2.log` | FAIL | R4-R6 required tool/stage settlement, typed error classes, and request-local raw-free correlation. |
| `plan_cloud_G07_3.log` | `code_review_cloud_G07_3.log` | FAIL | R7 required real request, stage, and in-flight tool deadlines to retain timeout observation ownership. |
| `plan_cloud_G07_4.log` | `code_review_cloud_G07_4.log` | FAIL | R7 remained at expired tool admission when that path beat the delayed stage timer callback. |
| `plan_cloud_G06_5.log` | `code_review_cloud_G06_5.log` | PASS | Expired tool admission now records timeout while preserving the caller-visible budget sentinel; fresh verification passed. |

## Implementation and Cleanup

- Wired the service-owned observer and clock through request, semantic stage, tool, cleanup, terminal, and total lifecycle observations.
- Added closed typed error classification and one bounded opaque correlation shared by all raw-free events for a request.
- Preserved `ErrSingleRequestInternalToolBudget` for callers while recording actual request, stage, in-flight tool, and expired-admission deadline winners as `timeout`.
- Kept iteration and output exhaustion classified as `internal_tool_budget` and added deterministic production-lifecycle race coverage.

## Final Verification

- `test -f agent-task/m-iop-owned-single-request-agent-execution/05+03_single_ingress/complete.log || test "$(compgen -G 'agent-task/archive/*/*/m-iop-owned-single-request-agent-execution/05+03_single_ingress/complete.log' | wc -l)" -eq 1` - PASS; exactly one predecessor completion was available.
- `test -f agent-task/m-iop-owned-single-request-agent-execution/12+05,06,08,11_internal_tool_loop/complete.log || test "$(compgen -G 'agent-task/archive/*/*/m-iop-owned-single-request-agent-execution/12+05,06,08,11_internal_tool_loop/complete.log' | wc -l)" -eq 1` - PASS; exactly one predecessor completion was available.
- `test -f agent-task/m-iop-owned-single-request-agent-execution/13+12_workspace_cleanup/complete.log || test "$(compgen -G 'agent-task/archive/*/*/m-iop-owned-single-request-agent-execution/13+12_workspace_cleanup/complete.log' | wc -l)" -eq 1` - PASS; exactly one predecessor completion was available.

- `gofmt -d apps/edge/internal/service/single_request.go apps/edge/internal/service/single_request_tool_loop.go apps/edge/internal/service/single_request_observation_test.go` - PASS; no output.

## Remaining Nits

- None.

## Follow-up Work

- Synchronize `agent-spec/runtime/edge-node-execution.md` during the Milestone spec-update flow; its limitation text still describes raw-free cleanup observation as deferred.
