# Complete - m-principal-provider-credential-slot-routing/08+03,04,07_secure_delivery

## Completion Time

2026-08-02

## Summary

Completed authenticated secure credential delivery, bounded lease injection/revocation, and deterministic projection shutdown evidence after eight plan iterations and seven formal reviews; final verdict PASS with `review_rework_count=6`.

## Loop History

| Plan | Review | Verdict | Notes |
|------|--------|---------|-------|
| `plan_cloud_G10_0.log` | `code_review_cloud_G10_0.log` | NOT REVIEWED | Initial secure-delivery scaffold was superseded before a formal verdict. |
| `plan_cloud_G10_1.log` | `code_review_cloud_G10_1.log` | FAIL | Secure transports, credential leases, adapter injection, revocation fencing, predecessor evidence, and implementation verification were incomplete. |
| `plan_cloud_G10_2.log` | `code_review_cloud_G10_2.log` | FAIL | Archived predecessor evidence had to replace the stale active-path probe, and the planned secure-delivery implementation was still absent. |
| `plan_cloud_G10_3.log` | `code_review_cloud_G10_3.log` | FAIL | Enrollment-bound peer names and periodic projection renewal/reconnect semantics required production fixes. |
| `plan_cloud_G10_4.log` | `code_review_cloud_G10_4.log` | FAIL | Serial projection delivery could let one stalled Edge block healthy Edges and server shutdown. |
| `plan_cloud_G07_5.log` | `code_review_cloud_G07_5.log` | FAIL | Projection batch admission did not observe cancellation while queued behind another batch. |
| `plan_cloud_G06_6.log` | `code_review_cloud_G06_6.log` | FAIL | The queued-refresh shutdown regression still depended on a fixed sleep and did not prove waiter entry. |
| `plan_cloud_G04_7.log` | `code_review_cloud_G04_7.log` | PASS | Observable waiter entry, prompt `Stop()` cancellation/join, race safety, process smoke, and secret guards passed fresh review. |

## Implementation and Cleanup

- Activated authenticated confidential credential paths with enrollment-bound peer identity checks and fail-closed transport behavior.
- Added bounded credential lease acquisition, dedicated sensitive delivery, request-local adapter auth injection, and revision/revocation fencing without generic secret-bearing metadata.
- Made projection fan-out concurrent and bounded, then made whole-batch admission context-aware so cancellation and shutdown cannot wait behind another batch.
- Replaced the queued-refresh fixed sleep with a one-shot observed-context handshake that proves `Stop()` cancels and joins the queued broadcast before releasing the occupied gate.

## Final Verification

- `go test -count=20 ./apps/control-plane/internal/wire -run 'TestEdgeServer(BroadcastProjectionCancellationDoesNotWaitForPriorBatch|StopCancelsProjectionRefreshWaitingForPriorBatch)$'` - PASS; 20 fresh repetitions completed in 0.087s.
- `go test -count=1 -race ./apps/control-plane/internal/wire` - PASS; the complete wire package completed in 3.009s with no race report.
- `go test -count=1 ./packages/go/auth ./packages/go/config ./packages/go/credentiallease` and `go test -count=1 ./apps/control-plane/... ./apps/edge/... ./apps/node/...` - PASS.
- Affected-package race packet - PASS on full rerun; an unrelated connector state timeout from the first packet did not reproduce in 20 focused race runs.
- `make test-control-plane-edge-wire` - PASS; Control Plane/Edge hello and disconnect smoke plus `TestSecureDeliveryThreeProcess` completed successfully.
- `go vet ./apps/control-plane/... ./apps/edge/... ./apps/node/... ./packages/go/...`, `git diff --check`, and the runtime-proto secret-structure guard - PASS with no findings.

## Remaining Nit

- None.

## Follow-up Work

- None.
