## Summary

Closed the remaining Anthropic and protocol-profile contract/spec drift after three official review loops; final verdict: PASS.

## Loop History

| Plan | Review | Verdict | Notes |
|------|--------|---------|-------|
| `plan_local_G06_01.log` | `code_review_cloud_G06_01.log` | FAIL | Contract/spec ownership, public Anthropic behavior, and retained verification evidence were incomplete or inconsistent with source. |
| `plan_cloud_G07_01.log` | `code_review_cloud_G07_01.log` | FAIL | Local-first count-tokens, the Anthropic error envelope and ingress 413 type, full-URL resolution, and complete retained evidence still required correction. |
| `plan_cloud_G06_02.log` | `code_review_cloud_G06_02.log` | PASS | The remaining contract/spec statements match source, all retained evidence is auditable, and fresh focused/full regressions pass. |

## Implementation and Cleanup

- Aligned the Anthropic outer contract and Edge-Node execution spec with provider-pool route admission, local-first configured `TokenCounter` execution, and native `anthropic_messages` count-tokens fallback admission.
- Documented the actual top-level Anthropic error envelope with nested `error.type`/`error.message` and the ingress 413 `invalid_request_error` classification.
- Aligned the Edge config inner contract and provider-pool config spec with complete-URL `ResolveOperationURL` behavior, including absolute URL preservation and one-time relative operation-path joining.
- Preserved deterministic source searches and complete focused/full regression output outside the repository with exact line counts, byte counts, and SHA-256 digests.

## Final Verification

- Retained implementation evidence under `/var/tmp/iop-contract-spec-sync-followup-g06/` - PASS; all 14 files were readable and every recorded line count, byte count, and SHA-256 digest matched `code_review_cloud_G06_02.log`.
- Independent reviewer evidence under `/var/tmp/iop-contract-spec-official-review.dUaH5Y/` - PASS; contract/source searches reproduced 125 lines/16,645 bytes and 73 lines/9,764 bytes with the same SHA-256 digests, and the forbidden-drift output remained empty.
- `env GOCACHE=/config/.cache/iop-contract-spec-official-review GOTMPDIR=/var/tmp/iop-contract-spec-official-build.C2txlX go test -count=1 ./packages/go/config -run 'TestBuiltInProtocolProfileURLs|TestProtocolProfileResolveOperationURLAbsolute|TestProtocolProfileProviderEndpointOverlay'` - PASS; `ok iop/packages/go/config`.
- `env GOCACHE=/config/.cache/iop-contract-spec-official-review GOTMPDIR=/var/tmp/iop-contract-spec-official-build.C2txlX go test -count=1 ./apps/edge/internal/openai -run 'TestAnthropic|TestResponses|Test.*ProviderAuth'` - PASS; `ok iop/apps/edge/internal/openai`.
- `go vet ./packages/go/...`, `go vet ./apps/edge/...`, and `go vet ./apps/node/...` with the reviewer cache/temp settings - PASS; no diagnostics.
- `go test -count=1 ./packages/go/...`, `go test -count=1 ./apps/edge/...`, and `go test -count=1 ./apps/node/...` with the reviewer cache/temp settings - PASS; all packages passed.
- `python3 agent-client/pi/install_test.py` - PASS; 4 tests passed.
- `bash -n agent-client/pi/install.sh` and `git diff --check` - PASS; no diagnostics.
- Repository Edge-Node diagnostic, auxiliary E2E smoke, full-cycle runtime execution, and live-provider smoke were not run because this follow-up changed only contract/spec wording and evidence; the affected deterministic runtime regressions passed and no external credential or endpoint was required.
