## Completion Time

2026-08-03

## Summary

Managed execution-preset authorization and external model identity completed after five reviewed loops; final verdict: PASS.

## Loop History

| Plan | Review | Verdict | Notes |
|------|--------|---------|-------|
| `plan_local_G07_0.log` | `code_review_cloud_G07_0.log` | FAIL | Found incorrect canonical managed binding resolution, lost selector credential identity, and incomplete zero/one/ambiguous authorization evidence. |
| `plan_cloud_G07_1.log` | `code_review_cloud_G07_1.log` | FAIL | Found missing native Anthropic virtual-model response rewriting and stale managed discovery/routing contracts. |
| `plan_cloud_G08_2.log` | `code_review_cloud_G08_2.log` | FAIL | Found an END-before-response-start regression and overbroad ordinary-native response identity wording. |
| `plan_cloud_G08_3.log` | `code_review_cloud_G08_3.log` | FAIL | Found a contradictory general Anthropic non-streaming response `model` field description. |
| `plan_cloud_G05_4.log` | `code_review_cloud_G05_4.log` | PASS | Confirmed consistent virtual-preset, ordinary-native, and Chat-bridge response model semantics with fresh focused, race, vet, contract, and diff verification. |

## Implementation / Cleanup

- Resolved each execution preset selector and stage through the authenticated principal's unique canonical projected route while preserving the selector route as credential authority.
- Preserved the requested virtual model identity across authorized Chat, Anthropic native JSON/SSE, and Chat-bridge responses without rewriting ordinary native provider responses.
- Kept response rewriting behind a successful native response-start boundary and retained fail-closed pre-response terminal behavior.
- Corrected the Anthropic external contract so the general response field matches the executable managed-auth and Native-vs-Bridge semantics.

## Final Verification

- `test -f agent-task/archive/2026/08/m-iop-hot-path-one-shot-execution/02+01_preset_generation/complete.log && test -f agent-task/archive/2026/08/m-iop-hot-path-one-shot-execution/03+01_preset_model_config/complete.log` - PASS; both required predecessor completion logs exist.
- `go test -count=1 ./apps/edge/internal/openai -run 'Test(AnthropicNativeVirtualPresetPreservesPublicModelIdentity|AnthropicNativeProviderFixturesPreserveBytesAndHeaders|AnthropicNativeProviderErrorPreservesStatusAndBody|AnthropicChatBridgeMixedContentToolsAndResponse)'` - PASS; fresh reviewer output `ok iop/apps/edge/internal/openai 0.082s`.
- `go test -race -count=1 ./packages/go/streamgate ./packages/go/config ./apps/edge/internal/openai ./apps/edge/internal/service` - PASS; all four packages passed with fresh race-enabled execution.
- `go vet ./apps/edge/internal/openai` - PASS; exit 0 with no output.
- ``rg --sort path -n --fixed-strings -- '- `model`: Authorized virtual presets echo the requested virtual model. Ordinary native responses preserve the provider response model, while Chat bridge responses use the converted Anthropic request model.' agent-contract/outer/anthropic-compatible-api.md`` - PASS; exact match at line 198.
- `git diff --check` - PASS; exit 0 with no output.

## Remaining Nits

- None.
