# Complete - m-principal-provider-credential-slot-routing/07+01,02,05_secret_material

## Completion Time

2026-08-01

## Summary

Completed the provider credential secret-at-rest boundary and evidence repair after four plan iterations and three formal reviews; final verdict PASS with `review_rework_count=2`.

## Loop History

| Plan | Review | Verdict | Notes |
|------|--------|---------|-------|
| `plan_cloud_G08_0.log` | `code_review_cloud_G09_0.log` | NOT REVIEWED | Initial unimplemented scaffold was superseded before a formal verdict. |
| `plan_cloud_G08_1.log` | `code_review_cloud_G09_1.log` | FAIL | Canonical credential-kind AAD binding and encryption-without-database startup boundaries required production fixes. |
| `plan_local_G06_2.log` | `code_review_cloud_G06_2.log` | FAIL | Unknown-kind durable-state and real Client/Edge listener-start assertions were incomplete. |
| `plan_cloud_G04_3.log` | `code_review_cloud_G04_3.log` | PASS | Exact state and listener-boundary assertions passed fresh focused and full Control Plane verification. |

## Implementation and Cleanup

- Canonicalized and validated provider credential kind before create-time sealing so persisted kind and authenticated-encryption context remain identical across rotation and restart.
- Rejected configured credential encryption without `database.url` before any network listener starts.
- Strengthened the unknown-kind regression with exact pre/post slot snapshots, credential revision-row counts, projection generation, and zero-sealer-call assertions.
- Matched the actual Client and Edge listener-start log messages in the encryption-without-database run regression.

## Final Verification

- `GOCACHE=/tmp/gocache-secret-material-evidence GOTMPDIR=/config/tmp go test -count=1 ./apps/control-plane/internal/credentialops -run 'TestServiceCreateCanonicalizesCredentialKindForAAD|TestServiceSecretHandlingFailureIsBlindAndDoesNotMutate'` - PASS; package completed in 0.982s.
- `GOCACHE=/tmp/gocache-secret-material-evidence GOTMPDIR=/config/tmp go test -count=1 ./apps/control-plane/cmd/control-plane -run 'TestComposeCredentialRuntimeEncryptionRequiresDatabase|TestRunWithEncryptionAndNoDatabaseDoesNotStartListener|TestRunAllowsUnconfiguredDatabase|TestComposeCredentialRuntimeSecretDisabledMode'` - PASS; package completed in 1.113s.
- `GOCACHE=/tmp/gocache-secret-material-evidence GOTMPDIR=/config/tmp go test -count=1 ./apps/control-plane/internal/credentialseal ./apps/control-plane/internal/credentialstore ./apps/control-plane/internal/credentialops` - PASS.
- `GOCACHE=/tmp/gocache-secret-material-evidence GOTMPDIR=/config/tmp go test -count=1 ./apps/control-plane/...` - PASS.
- `GOCACHE=/tmp/gocache-secret-material-evidence GOTMPDIR=/config/tmp go vet ./apps/control-plane/...` - PASS.
- Scoped stale-string/state-discard scan, `git diff --check`, reviewer-probe absence check, and credential material leak guard - PASS with no matches.
