# Complete - m-iop-owned-single-request-agent-execution/01_preset_config

## Completion Date

2026-08-06

## Summary

Completed the fixed single-request preset config admission work after five plan snapshots and three verdict-bearing review loops; final verdict PASS.

## Loop History

| Plan | Review | Verdict | Notes |
|------|--------|---------|-------|
| `plan_local_G07_0.log` | `code_review_cloud_G07_0.log` | Not reviewed | Initial pair was superseded before implementation evidence or a verdict. |
| `plan_local_G07_1.log` | `code_review_cloud_G07_1.log` | Not reviewed | Parent pair was split before implementation evidence or a verdict. |
| `plan_local_G04_2.log` | `code_review_cloud_G04_2.log` | FAIL | Route/policy divergence, second-based schema drift, and missing nested strict-decode evidence required rework. |
| `plan_cloud_G04_3.log` | `code_review_cloud_G04_3.log` | FAIL | The validator was conformant, but direct regression evidence for every binding and strict-decode branch was incomplete. |
| `plan_cloud_G01_4.log` | `code_review_cloud_G02_4.log` | PASS | Independent role/binding, removed-key, and exact nested-key diagnostics closed all remaining evidence gaps. |

## Implementation and Cleanup

- Added a typed fixed single-request preset policy with opaque workspace binding, millisecond request/stage limits, plan/work/review stage bindings, deep-clone isolation, and fail-closed validation.
- Enforced one effective selector/plan/work/review model-and-option binding, catalog membership, plan/review high reasoning, and work-stage reasoning absence.
- Added deterministic regression coverage for plan/work/review model and option divergence, route-only dangling and reasoning leakage, removed second-based keys, nested unknown keys, cap boundaries, compatibility, and clone isolation.

## Final Verification

- `gofmt -d packages/go/config/single_request_execution_preset_config_test.go` - PASS; no output.
- `go test ./packages/go/config -run 'TestLoadEdgeSingleRequestExecutionPresetRejects(DivergentEffectiveBindings|InvalidShape|UnknownNestedFields)$' -count=1` - PASS; `ok iop/packages/go/config`.
- `go build ./packages/go/...` - PASS; no output.
- `go test ./packages/go/config -run 'Test(LoadEdgeSingleRequestExecutionPreset|CloneExecutionPresetSingleRequestIsolation|LoadEdgeExecutionPresetCatalog|LoadEdgeExecutionPresetRejectsInvalidShape)$' -count=1` - PASS; `ok iop/packages/go/config`.
- `go test ./packages/go/config -count=1` - PASS; `ok iop/packages/go/config`.
- `go vet ./packages/go/...` - PASS; no output.
- `go test ./packages/go/... -count=1` - PASS; all shared Go packages passed.
- `git diff --check` - PASS; no output.

## Remaining Nits

- None.
