## Summary

Closed the root README D04 ownership correction after four plan pairs: two superseded unreviewed pairs, one failed semantic-boundary review, and the final PASS.

## Loop History

| Plan | Review | Verdict | Notes |
|------|--------|---------|-------|
| `plan_local_G07_0.log` | `code_review_cloud_G07_0.log` | NOT REVIEWED | The initial pair was superseded before implementation review. |
| `plan_local_G07_1.log` | `code_review_cloud_G07_1.log` | NOT REVIEWED | The pair was superseded after its transfer-reference direction conflicted with the pinned D04 disposition. |
| `plan_local_G07_2.log` | `code_review_cloud_G07_2.log` | FAIL | The broad cleanup and regression checks passed, but the root README retained semantically stale IOP ownership language. |
| `plan_local_G04_3.log` | `code_review_cloud_G04_3.log` | PASS | The D04 provider-only boundary and deterministic documentation evidence were corrected and independently verified. |

## Implementation and Cleanup

- Limited IOP ownership to external inference APIs and model/provider/device execution, cancellation, status, usage, and lifecycle in the root README.
- Assigned agent, workspace/tool, terminal/PTY, and remote-host control to independent Chronos Server and Chronos Node, while describing external tools and agents as ordinary inference clients.
- Preserved the pinned ownership manifest and transferred standalone contract digests without changing later-task source.
- Corrected the active review's non-behavioral `git diff --check` explanation so it reports only the evidence that command proves.

## Final Verification

- `go version && go env GOMOD` - PASS; reviewer preflight reported `go version go1.26.2 linux/arm64` and `/config/workspace/iop-s1/go.mod`.
- Positive README D04 boundary assertion - PASS; exit code 0 with empty stdout/stderr.
- Forbidden README semantic scan - PASS; exit code 0 with no matches.
- Manifest and transferred-contract SHA-256 assertions - PASS; exit code 0 with both expected digests preserved.
- `git diff --check` - PASS; exit code 0 with no whitespace errors.
- Archived `code_review_cloud_G07_2.log` build and regression evidence - PASS; `make build-local` and fresh `go test -count=1 ./...` both completed successfully before this documentation-only follow-up.

## Remaining Nits

- None.

## Follow-up Work
