- `GOCACHE=/tmp/go-build-auth-validate GOMODCACHE=/tmp/go-mod-auth-validate go build -o /tmp/update-server-auth-validate ./cmd/server` -> passed
- `GOCACHE=/tmp/go-build-auth-validate GOMODCACHE=/tmp/go-mod-auth-validate go build -o /tmp/update-migrate-auth-validate ./cmd/migrate` -> passed
- live smoke checks against `127.0.0.1:18082` after starting `/tmp/update-server-auth-validate` with fresh bootstrap credentials and a fresh `DATA_DIR`:
  - `GET /admin` -> `303 See Other` to `/admin/login`
  - `GET /admin/login` -> `200 OK`
  - `POST /admin/login` -> `303 See Other` with session cookie
  - `GET /admin` with valid cookie -> `200 OK`
  - SQLite inspection confirmed `sessions.token_hash` stores the SHA-256 of the cookie token, not the raw token
  - `POST /admin/logout` -> `303 See Other`
  - `GET /admin` with the old cookie after logout -> `303 See Other` to `/admin/login`
  - SQLite inspection confirmed the session row was invalidated

## Findings

No blocking findings.

The stage satisfies the agreed scope:

- bootstrap admin creation is wired from environment configuration;
- passwords are hashed with bcrypt;
- session tokens are generated securely and stored hashed in SQLite;
- the `/admin` route group is protected by session middleware and role checks;
- login and logout behavior works in live validation, including old-cookie rejection after logout.

## Required Fixes

None.

## Optional Improvements

- Decide explicitly in a later stage whether the login endpoint should stay generic for any active user session or reject non-admin roles up front for the current admin-only UI.
- Add CSRF protection when the security-hardening stage begins, especially for `POST /admin/logout` and future admin forms.

## Status

`APPROVED`
