# Complete - m-iop-agent-chronos-extraction-decoupling/07+06_remove_go_surface

## Completion Time

2026-08-02

## Summary

Closed the standalone Go/state/runtime surface removal after one superseded unreviewed broad pair and one completed review loop; final verdict: PASS.

## Loop History

| Plan | Review | Verdict | Notes |
|------|--------|---------|-------|
| `plan_cloud_G09_0.log` | `code_review_cloud_G09_0.log` | NOT REVIEWED | The original broad decoupling pair was split before implementation and retained as exact prior-loop evidence. |
| `plan_local_G07_1.log` | `code_review_cloud_G07_1.log` | PASS | The exact 140-row Go/config/proto/smoke subset was removed after the transfer gate, retained generic packages remained buildable, and fresh repository regression passed. |

## Implementation and Cleanup

- Verified the exact predecessor PASS completion and corrected pinned-transfer receipt before accepting deletion evidence.
- Removed exactly the 140 manifest-classified `transfer`/`remove` paths owned by this child while preserving `packages/go/agentruntime`, `packages/go/agentprovider/cli`, and the contract/spec/UI surfaces assigned to later children.
- Hardened the retained CLI workspace test cleanup so permission-restricted temporary directories are restored reliably when tests use a repository-local temporary root.

## Final Verification

- `go version && go env GOMOD` - PASS; `go version go1.26.2 linux/arm64` and `/config/workspace/iop-s1/go.mod`.
- Active-plan Verification 1 predecessor/receipt command - PASS; one exact predecessor `complete.log`, final PASS evidence, corrected manifest SHA-256, and the 15-key redacted receipt contract all matched.
- Active-plan Verification 2 manifest and removed-path command - PASS; exactly 140 classified rows and zero residual task-owned paths.
- `test ! -e cmd/iop-provider-smoke` - PASS.
- Active-plan Verification 4 preservation command - PASS; both generic Go package roots and the deferred contract/spec/UI surfaces remain present.
- `mkdir -p .tmp && TMPDIR=/config/workspace/iop-s1/.tmp GOTMPDIR=/config/workspace/iop-s1/.tmp go test -count=1 ./...` - PASS; all current Go packages completed with exit code 0.
- `git diff --check` - PASS with no whitespace errors.

## Remaining Nits

- None.

## Follow-up Work

- None.
