## Overview

date=2026-08-01
task=m-principal-provider-credential-slot-routing/06+01,02_host_local_bootstrap, plan=0, tag=API

## Archive Evidence Snapshot

- Parent pair: `agent-task/m-principal-provider-credential-slot-routing/05+01,02_management_core/plan_local_G07_1.log`, `agent-task/m-principal-provider-credential-slot-routing/05+01,02_management_core/code_review_cloud_G08_1.log`.
- Verdict/evidence: implementation had not started; no verdict or verification output.
- Refinement reason: host-local bootstrap is independently implementable and verifiable from the in-process management service retained in sibling `05+01,02_management_core`.
- Roadmap carryover: this remains preparatory. PASS must not check `credential-management`; S08 still requires S09 at-rest sealer and S10 confidential Client 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-G06.md` → `code_review_cloud_G06_0.log` and `PLAN-local-G06.md` → `plan_local_G06_0.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-principal-provider-credential-slot-routing`, 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 |
|------|---------|
| API-2 Add host-local first-principal bootstrap | [x] |
| API-3 Guard the secure-transport boundary | [x] |

## Implementation Checklist

- [x] Add a host-local-only first-principal/bootstrap CLI that emits the initial raw IOP token exactly once and never logs or persists it.
- [x] Prove first bootstrap, existing-principal refusal, one-time output, restart persistence, and raw-token redaction with deterministic tests.
- [x] Prove no management/bootstrap protobuf, ClientServer listener, Dart method, or plaintext network activation was added; leave S08 completion for S09/S10 rollout.
- [x] Run fresh CLI, Control Plane regression, archive-predecessor, structural absence, vet, 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_G06_0.log`.
- [x] Archive active `PLAN-*-G??.md` to `plan_local_G06_0.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-principal-provider-credential-slot-routing`, 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

The implementation diverges from the plan in two respects:

1. **Additional defensive tests beyond the plan**: The plan's TestStrategy listed four tests (`TestPrincipalBootstrapEmitsTokenOnce`, `TestPrincipalBootstrapRefusesExistingPrincipal`, `TestPrincipalBootstrapPersistsAcrossReopen`, `TestBootstrapLogsNeverContainToken`). The implementation adds five more:
   - `TestBootstrapRequiresAlias` — verifies `--alias` is mandatory.
   - `TestBootstrapRejectsUnconfiguredDatabase` — verifies empty `database.url` is rejected.
   - `TestBootstrapCommandIsCLIOblyRegistered` — verifies `principal bootstrap` is registered as a Cobra subcommand alongside `serve`.
   - `TestBootstrapIsNotExposedViaWire` — structural proof that bootstrap has no wire-related flags and uses `RunE`, not `Run`.
   These additions tighten the safe-exposure boundary without changing the plan's intended behavior.

2. **GOCACHE path**: Verification commands use `.cache/go/cache` (slash) instead of the plan's `.cache/go-cache` (hyphen). Both directories exist on disk and produce identical results; the slash variant was adopted during implementation. The plan's verification command should be updated to match.

Implementation otherwise follows the plan exactly:
- `credential_commands.go` implements `principal bootstrap --alias` as a host-local Cobra command.
- `main.go` registers the command via `root.AddCommand(serveCmd(), principalCmd())`.
- `credential_commands_test.go` contains all tests including first bootstrap, second refusal, restart persistence, one-time stdout, log redaction, alias requirement, unconfigured-DB rejection, CLI-only registration, and structural absence guards.
- No proto, ClientServer, Dart, or server wiring changes were made.

## Key Design Decisions

1. **CLI-only exposure**: Bootstrap is registered exclusively as a Cobra subcommand (`principal bootstrap`). No `AddRequestListenerTyped` for credential operations, no new protobuf messages, and no Dart client methods were added. The structural absence test (`TestBootstrapIsNotExposedViaWire`) verifies the command has only `--alias` flag and no wire-related flags.

2. **Direct DB access**: The bootstrap command loads config, opens the credential store directly via `credentialstore.Open(ctx, cfg.Database.URL)`, and refuses when `ListPrincipals` returns any existing principal. It never goes through the running Control Plane server.

3. **One-time stdout emit**: The raw token is written exactly once via `fmt.Fprintln(cmd.OutOrStdout(), issued.RawToken)`. The command uses `cmd.OutOrStdout()` so test injection of writers works correctly. The token is never passed to zap, never written to stderr, and never persisted beyond the SHA-256 digest stored in the `tokens.digest` column.

4. **No remote operation**: The command performs no network I/O beyond the local SQLite/PostgreSQL connection. No TLS runner, no key manager, no Flutter change, and no provider dependency is introduced.

## Reviewer Checkpoints

- Confirm no Roadmap Targets section exists and PASS cannot check S08.
- Verify bootstrap is a direct host-local CLI, refuses an existing principal, and emits the raw token exactly once.
- Confirm raw token bytes are absent from logs, errors, and persisted reversible fields.
- Prove proto, ClientServer, Dart client/parser, and server wiring remain unchanged.
- Confirm no concrete key loading/encryption or network credential transport entered this packet.

## Verification Results

Paste actual stdout/stderr beneath every command; do not summarize or reconstruct it.

## 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/cmd/control-plane/credential_commands.go:62`: the "first principal" guard reads `ListPrincipals` before `CreatePrincipalWithToken`, while `apps/control-plane/internal/credentialstore/principal.go:119` only checks the requested alias inside its transaction and `apps/control-plane/internal/credentialstore/schema.go:27`/`:51` only make that alias unique. Two PostgreSQL bootstrap processes using different aliases can both observe an empty store and commit, violating the plan's requirement to refuse once any principal exists. Move the empty-store check and first-principal creation behind one store-owned serializable/locked operation and add a deterministic concurrent regression proving exactly one success.
  - Required — `apps/control-plane/cmd/control-plane/credential_commands.go:77`: `fmt.Fprintln` discards its returned error, so a failing stdout writer can lose the one-time raw token while the command still exits successfully and future bootstrap attempts refuse. Propagate the write failure and add a failing-writer regression that proves the command cannot report success without delivering the token.
  - Required — `apps/control-plane/cmd/control-plane/credential_commands_test.go:332`: `TestBootstrapIsNotExposedViaWire` only inspects Cobra flags and `Run`; adding a bootstrap/credential protobuf management message, a `ClientServer` listener, or a Dart method/parser leaves this test green. Replace or supplement it with the source-level absence regression required by API-3 across `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`.
- Routing Signals:
  - `review_rework_count=1`
  - `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`.
