## Summary

Completed in one implemented review after one pre-implementation replan; final verdict PASS.

## Loop History

| Plan | Review | Verdict | Notes |
|------|--------|---------|-------|
| `plan_cloud_G05_0.log` | `code_review_cloud_G05_0.log` | No verdict | Unimplemented draft superseded by the user-requested second plan review. |
| `plan_cloud_G05_1.log` | `code_review_cloud_G05_1.log` | PASS | The repeat hold envelope and all four exact-wire large-event tunnel variants passed fresh focused and race verification. |

## Implementation and Cleanup

- Added a private 1,048,576-rune maximum buffer for both repeat-policy hold participants while preserving the 500-rune evidence window and the schema gate's 4,096-rune default.
- Added a production-registration contract test for the participant and composed bounds.
- Added Chat/Responses content/reasoning tunnel regressions for one 5,000-rune semantic event with exact provider-wire release and no recovery dispatch.

## Final Verification

- `command -v go && readlink -f "$(command -v go)" && go version && go env GOROOT && go env GOMOD` — PASS; `/config/.local/bin/go` resolves to `/config/opt/go/bin/go`, Go is `go1.26.2 linux/arm64`, `GOROOT=/config/opt/go`, and `GOMOD=/config/workspace/iop/go.mod`.
- `gofmt -d apps/edge/internal/openai/stream_gate_filters.go apps/edge/internal/openai/stream_gate_filters_test.go apps/edge/internal/openai/stream_gate_pipeline_test.go` — PASS; no formatting diff.
- `go test -count=1 ./apps/edge/internal/openai -run '^Test(OpenAIRepeatHoldBufferContract|OpenAIOutputFilterRegistrations)$'` — PASS; `ok iop/apps/edge/internal/openai`.
- `go test -count=1 ./apps/edge/internal/openai -run '^TestStreamGateConfiguredRepeatGuardLargeTunnelEvent$'` — PASS; all four variants passed.
- `go test -count=1 ./apps/edge/internal/openai -run '^Test(OpenAIRepeatHoldBufferContract|StreamGateConfiguredRepeatGuardLargeTunnelEvent)$'` — PASS; `ok iop/apps/edge/internal/openai`.
- `go test -race -count=1 ./packages/go/streamgate ./apps/edge/internal/openai ./packages/go/config` — PASS; all three packages passed with the race detector.
- `git diff --check` — PASS; no whitespace errors.
- Repository Edge-Node diagnosis, auxiliary E2E smoke, live-provider smoke, and full-cycle startup were not run because the available flows do not enable the blocking `repeat_guard` configuration and cannot exercise the changed buffer path; the deterministic production registry/source/Core/sink regression is the accepted task oracle.
