# Complete - m-iop-owned-single-request-agent-execution/18+17_plan_stage

## Completion Time

2026-08-07

## Summary

Closed case-folded JSON field aliasing at the private Plan/provider boundary after five reviewed loops; final verdict PASS.

## Loop History

| Plan | Review | Verdict | Notes |
|------|--------|---------|-------|
| `plan_local_G06_1.log` | `code_review_cloud_G06_1.log` | FAIL | The initial implementation lacked the complete Plan runner, frozen-authority enforcement, ordered-frame validation, and trustworthy S08 tests. |
| `plan_cloud_G07_2.log` | `code_review_cloud_G07_2.log` | FAIL | Provider envelope semantics and the required failure/limit/deadline test matrix remained incomplete. |
| `plan_cloud_G05_3.log` | `code_review_cloud_G05_3.log` | FAIL | Strict nested JSON decoding, duplicate-key rejection, and no-artifact-write evidence remained incomplete. |
| `plan_cloud_G04_4.log` | `code_review_cloud_G04_4.log` | FAIL | Go's case-insensitive struct matching still accepted case-mutated names and case-folded aliases. |
| `plan_cloud_G04_5.log` | `code_review_cloud_G04_5.log` | PASS | Exact canonical field admission and deterministic alias regressions close the inherited Required finding. |

## Implementation and Cleanup

- Added exact canonical member validation before typed decoding for private provider response, choice, message, and Plan result objects.
- Added deterministic case-variant and case-folded-alias regressions proving generic provider failure, acquired-tunnel closure, and zero Plan artifact write attempts or persistence.
- Preserved the private, uninstalled Plan component boundary; Work, Review/repair, outer activation, generic error/cancel integration, and S12 Claude/Mac qualification remain outside this task.

## Final Verification

- `bash -c 'set -euo pipefail; shopt -s nullglob; candidates=(agent-task/m-iop-owned-single-request-agent-execution/17_*/complete.log agent-task/m-iop-owned-single-request-agent-execution/17+*/complete.log agent-task/archive/*/*/m-iop-owned-single-request-agent-execution/17_*/complete.log agent-task/archive/*/*/m-iop-owned-single-request-agent-execution/17+*/complete.log); printf "%s\n" "${candidates[@]}"; ((${#candidates[@]} == 1))'` - PASS; found exactly the archived `17_internal_artifact_wire` predecessor.
- `go test ./apps/edge/internal/openai -run '^TestSingleRequestProviderStage' -count=1` - PASS.
- `go test ./apps/edge/internal/openai -run '^TestSingleRequestPlanStage' -count=1` - PASS.
- `go test -race ./apps/edge/internal/openai -run 'TestSingleRequest(ProviderStage|PlanStage)' -count=1` - PASS.
- `go test ./apps/edge/internal/service ./apps/edge/internal/openai -run 'TestSingleRequest(Binding|PresetBinding|ProviderStage|PlanStage)' -count=1` - PASS.
- `go vet ./apps/edge/internal/service ./apps/edge/internal/openai` - PASS.
- `go test ./apps/edge/... -count=1` - PASS across all Edge packages.
- Alias regression discovery, no-activation guard, living-spec search, `gofmt -d`, and `git diff --check` - PASS.
- External full-cycle execution - not applicable to this private uninstalled S08 component; actual Claude/Mac qualification remains S12 `claude-smoke` scope.

## Remaining Nit

- None.

## Follow-up Work

- None for this task.
