# Complete - m-iop-owned-single-request-agent-execution/17_internal_artifact_wire

## Completed At

2026-08-07

## Summary

Completed the request-owned PLAN/REVIEW artifact wire and lifecycle foundation in one review loop with a final PASS verdict.

## Loop History

| Plan | Review | Verdict | Notes |
|------|--------|---------|-------|
| `plan_cloud_G09_0.log` | `code_review_cloud_G09_0.log` | PASS | Closed artifact protocol, Node ownership, Edge lifecycle integration, contract/spec synchronization, and verification all passed. |

## Implementation And Cleanup

- Added generated Go and Dart bindings for the closed PLAN/REVIEW and READ/WRITE artifact protocol.
- Added bounded, inventoried Node artifact access with descriptor-relative no-follow reads and canonical raw-free terminals.
- Added exact-generation Edge dispatch, response validation, shared lazy workspace open, in-flight ownership, and terminal cleanup integration.
- Synchronized the Edge-Node runtime contract and current implementation spec while keeping provider-specific stage drivers and Claude qualification deferred to their dependent tasks.

## Final Verification

- `make proto && make proto-dart` - PASS; both generators exited zero and reproduced the tracked bindings.
- `go test ./packages/go/workspaceprotocol ./apps/node/internal/workspace ./apps/node/internal/node ./apps/node/internal/transport ./apps/edge/internal/transport ./apps/edge/internal/service -count=1` - PASS; all focused cross-boundary packages passed freshly.
- `go test -race ./apps/edge/internal/service ./apps/node/internal/transport -run 'Test.*(WorkspaceArtifact|SingleRequestArtifact)' -count=1` - PASS; artifact lifecycle and transport tests passed with no race report.
- `go vet ./packages/go/... && go vet ./apps/node/... && go vet ./apps/edge/internal/service` - PASS; no diagnostics.
- `go test ./packages/go/... ./apps/node/... ./apps/edge/... -count=1` - PASS; broader shared, Node, and Edge regressions passed freshly.
- `make client-test` - PASS; all 44 Flutter tests passed.
- `go test -race -count=1 ./packages/go/config ./packages/go/streamgate ./apps/edge/internal/openai ./apps/edge/internal/service ./apps/node/internal/node ./apps/node/internal/transport` - PASS; the SDD-wide race baseline passed.
- `go test -race -count=1 ./apps/node/internal/workspace -run 'Test.*InternalArtifact'` - PASS; Node internal artifact tests passed with no race report.
- `git diff --check` and `gofmt -d` over the changed Go files - PASS; no whitespace or formatting drift.

## Remaining Nits

- None.

## Follow-up Work

- Provider-specific Plan, Work, Review/repair drivers and actual Claude/Mac qualification remain owned by the already-split dependent tasks; this PASS is contribution evidence, not a direct Milestone Task completion assertion.
