## Summary

Completed four plan iterations (three review verdicts) with a final PASS after closing the workspace wire cancellation, admitted-reference, typed identity/status, and contradictory terminal/error validation gaps.

## Loop History

| Plan | Review | Verdict | Notes |
|------|--------|---------|-------|
| `plan_cloud_G08_0.log` | `code_review_cloud_G09_0.log` | NOT REVIEWED | First-pass pair was superseded before implementation because immutable coordinator identity and generated-client verification were missing from the plan. |
| `plan_cloud_G08_1.log` | `code_review_cloud_G09_1.log` | FAIL | Required R1-R3 identified in-flight cancellation serialization, admitted-reference override, and incomplete typed response validation. |
| `plan_cloud_G08_2.log` | `code_review_cloud_G09_2.log` | FAIL | R1 and R2 passed; R3 still accepted an allowed terminal carrying a failure error code or raw error text. |
| `plan_cloud_G05_3.log` | `code_review_cloud_G05_3.log` | PASS | All four response families now reject contradictory terminal/error outcomes with a nil response and stable raw-free error. |

## Implementation and Cleanup

- Added the dedicated typed Edge-Node workspace open/tool/cancel/cleanup wire while keeping it separate from provider `RunRequest`, provider execution, and closed `NodeCommand`.
- Preserved exact admitted Node/generation fencing, made in-flight cancellation reach the captured Node exactly once, and rejected workspace-reference overrides before transport dispatch.
- Validated echoed identities and closed response outcomes for all four response families; accepted terminals now require `WORKSPACE_ERROR_CODE_UNSPECIFIED` and an empty raw error.
- Added deterministic cancellation, no-send, invalid-response, timeout, and eight-case contradictory-outcome regressions; corrected a stale explanatory comment during final review.

## Final Verification

- `test -f agent-task/m-iop-owned-single-request-agent-execution/08+03,07_workspace_admission/complete.log || test "$(compgen -G 'agent-task/archive/*/*/m-iop-owned-single-request-agent-execution/08+03,07_workspace_admission/complete.log' | wc -l)" -eq 1` - PASS; the admission dependency resolved uniquely.
- `go test -race ./apps/edge/internal/service ./apps/node/internal/transport -run 'Test(WorkspaceWire|SessionWorkspace)' -count=1` - PASS; both packages passed uncached race verification.
- `go test ./apps/edge/internal/node ./apps/edge/internal/service ./apps/edge/internal/transport ./apps/node/internal/transport -count=1` - PASS; all four affected packages passed uncached regression verification.
- `go vet ./apps/edge/internal/node ./apps/edge/internal/service ./apps/edge/internal/transport ./apps/node/internal/transport` - PASS; no diagnostics.
- `git diff --check` plus `gofmt -d` and direct trailing-whitespace checks for both untracked workspace wire files - PASS.
- `go test -v ./apps/edge/internal/service -run '^TestWorkspaceWireRejectsContradictoryTerminalOutcome$' -count=1` - PASS; all eight open/tool/cancel/cleanup error-code and raw-error variants passed.
