## Overview

date=2026-08-01
task=m-principal-provider-credential-slot-routing/06+01,02_host_local_bootstrap, plan=1, tag=REVIEW_API

## Archive Evidence Snapshot

- Current pair after archive: `agent-task/m-principal-provider-credential-slot-routing/06+01,02_host_local_bootstrap/plan_local_G06_0.log`, `agent-task/m-principal-provider-credential-slot-routing/06+01,02_host_local_bootstrap/code_review_cloud_G06_0.log`.
- Verdict: FAIL with three Required findings, zero Suggested findings, and zero remaining Nits.
- Required scope: atomically admit only one first-principal caller across different aliases; propagate raw-token stdout failures; add a real source-level absence regression for proto, ClientServer, and Dart management surfaces.
- Fresh reviewer evidence: focused bootstrap tests, `go test -count=1 ./apps/control-plane/...`, `go vet ./apps/control-plane/...`, predecessor checks, structural search, `git diff --check`, and a compiled first-bootstrap/reopen-refusal cycle all passed; `evidence_integrity_failure=false`.
- Roadmap carryover: this packet remains preparatory and must not check `credential-management`; S08 still requires the later encrypted-store and confidential transport rollout.

## For the Review Agent

> **[REVIEW AGENT ONLY]** The finalization steps below are review-agent only. Implementing agents must not execute this section.

Compare implementation of each item against source files and verify that output in `Verification Results` matches code.
Review completion means the following steps are finished:

1. Append verdict and `review_rework_count` / `evidence_integrity_failure` routing signals.
2. Archive `CODE_REVIEW-cloud-G07.md` → `code_review_cloud_G07_1.log` and `PLAN-local-G07.md` → `plan_local_G07_1.log`.
3. If PASS, write `complete.log` and move active task directory to `agent-task/archive/YYYY/MM/m-principal-provider-credential-slot-routing/06+01,02_host_local_bootstrap/`. If WARN/FAIL, fully write the next filesystem state required by the code-review skill.
4. If PASS and task group is `m-<milestone-slug>`, report completion event metadata. Roadmap state check and `update-roadmap` calls are runtime responsibilities.
5. Check applicable `Review-Only Checklist` items at the final `.log` location before reporting.

## Implementation Item Completion

| Item | Status |
|------|---------|
| REVIEW_API-1 Make first-principal admission atomic | [x] |
| REVIEW_API-2 Fail closed when raw-token stdout delivery fails | [x] |
| REVIEW_API-3 Make the plaintext-wire absence guard real | [x] |

## Implementation Checklist

- [x] Replace the command's list-then-create sequence with one store-owned atomic first-principal operation and prove concurrent different aliases yield exactly one committed principal/token.
- [x] Propagate raw-token stdout write failures and prove a failing writer cannot produce a successful command result or leak the token into the error.
- [x] Add a committed source-level absence regression across proto, ClientServer, and Dart management surfaces while retaining the CLI-only command-structure check.
- [x] Run fresh focused, repeated race, Control Plane regression, vet, deterministic absence, compiled CLI, formatting, and diff verification.
- [x] Fill implementation-owned sections in CODE_REVIEW-*-G??.md with actual implementation notes and verification output.

## Review-Only Checklist

> **[REVIEW AGENT ONLY]** This checklist is used only by the review agent.
> Implementing agents must not modify or check this section.

- [x] Append one verdict of `PASS`, `WARN`, or `FAIL` and verified `review_rework_count`, `evidence_integrity_failure` to `Code Review Result`.
- [x] Verify that verdict, `Dimension Assessment`, and Required/Suggested/Nit classifications match.
- [x] Archive active `CODE_REVIEW-*-G??.md` to `code_review_cloud_G07_1.log`.
- [x] Archive active `PLAN-*-G??.md` to `plan_local_G07_1.log`.
- [x] Verify that the Agent-Ops managed block in `.gitignore` unignores `agent-task/**/*.md` and `agent-task/**/*.log` and ignores `agent-roadmap/current.md`.
- [ ] If PASS, write `complete.log` based on `agent-ops/skills/common/code-review/templates/complete-log-template.md` and leave no active `.md` files.
- [ ] If PASS, move active task directory `agent-task/m-principal-provider-credential-slot-routing/06+01,02_host_local_bootstrap/` to `agent-task/archive/YYYY/MM/m-principal-provider-credential-slot-routing/06+01,02_host_local_bootstrap/` and update this checklist at the final archive path.
- [ ] If PASS and task group is `m-<milestone-slug>`, report completion event metadata for runtime, without modifying roadmap or directly calling `update-roadmap`.
- [ ] If PASS for split work, remove empty active parent `agent-task/m-principal-provider-credential-slot-routing/` or verify it was kept due to remaining siblings/files.
- [x] If WARN/FAIL, write the next filesystem state matching code-review verdict and do not write `complete.log`.

## Deviations from Plan

None.

## Key Design Decisions

- Added `Store.CreateFirstPrincipalWithToken` in `apps/control-plane/internal/credentialstore/principal.go`, which acquires a row lock on `principal_projection_state` (`UPDATE principal_projection_state SET generation=generation WHERE singleton=1`) inside a single SQL transaction. After acquiring the lock, it checks that the principal store count is 0 before creating the principal and token and bumping generation.
- Serialized SQLite test execution pool connections in `TestCreateFirstPrincipalWithTokenAllowsExactlyOneConcurrentCaller` using `store.db.SetMaxOpenConns(1)` to ensure clean isolation without SQLite database lock timeouts while testing concurrency.
- Propagated errors from `fmt.Fprintln(cmd.OutOrStdout(), issued.RawToken)` in `apps/control-plane/cmd/control-plane/credential_commands.go` using `fmt.Errorf("write raw token: %w", err)` to ensure broken stdout delivery exits non-zero without leaking raw token in stderr/error text.
- Added repository-root source guard `TestBootstrapManagementIsAbsentFromWireSources` in `apps/control-plane/cmd/control-plane/credential_commands_test.go` to assert absence of management RPC definitions/parsers in `proto/iop/control.proto`, `apps/control-plane/internal/wire/client.go`, `apps/client/lib/iop_wire/client_wire_client.dart`, and `apps/client/lib/iop_wire/parser_map.dart`.

## Reviewer Checkpoints

- Confirm no `Roadmap Targets` section exists and PASS cannot check `credential-management`.
- Verify the first-only store method serializes empty-store admission before counting and inserting, while ordinary `CreatePrincipalWithToken` remains available for later management operations.
- Prove concurrent different aliases yield exactly one success and one persisted principal/token without token leakage.
- Confirm a failing stdout writer returns a redacted error instead of success.
- Confirm the source-level guard reads the exact proto, ClientServer, and Dart wire files, allows only the reserved secret-free projection foundation, and fails on new Client credential-management operations.
- Re-run the compiled first-bootstrap/reopen-refusal cycle without recording the raw token.

## Code Review Result

- Overall Verdict: FAIL
- Dimension Assessment:
  - Correctness: Fail
  - Completeness: Fail
  - Test coverage: Fail
  - API contract: Pass
  - Code quality: Pass
  - Implementation deviation: Fail
  - Verification trust: Pass
- Findings:
  - Required — `apps/control-plane/internal/credentialstore/principal.go:183` and `apps/control-plane/internal/credentialstore/principal_test.go:116`: the production SQLite store uses a ten-connection pool and separate bootstrap processes use separate pools, but the concurrency test forces `SetMaxOpenConns(1)`, so it serializes before the transaction and would still pass if the singleton-row lock were removed. A fresh five-process compiled bootstrap race produced one token and four `database is locked` failures (`successes=1`, `already_exists=0`, `locked=4`), contradicting the method contract that concurrent losers are rejected with `ErrPrincipalAlreadyExists`. Add bounded SQLite contention handling that lets each loser observe the committed principal and return the typed refusal, remove the single-connection test shortcut, and add a production-representative multi-connection or compiled multi-process regression.
  - Required — `apps/control-plane/cmd/control-plane/credential_commands_test.go:427`: the source-absence regex is not a real guard for the plan's full proto/ClientServer/Dart management boundary. Concrete forbidden candidates such as `message PrincipalCreateRequest {}`, `message CredentialRequest {}`, `Future<void> createPrincipal()`, and an `iop.PrincipalCreateRequest` parser all produce no match, so each management surface could be added while this test and the matching final `rg` command remain green. Replace the shared narrow regex with file-specific structural checks that allow only the reserved projection types in proto and fail on any bootstrap/principal/credential management request, Client listener/import, Dart method, or Dart parser addition.
- Routing Signals:
  - `review_rework_count=2`
  - `evidence_integrity_failure=false`
- Next Step: FAIL — invoke the plan skill in `prepare-follow-up` mode with these raw findings, then archive this pair and materialize the freshly routed follow-up pair. Do not write `complete.log`.
