docs(12-05): mark VERIFICATION.md passed — all 5 truths verified

- test_nextcloud_connect_persists: provider=nextcloud routes to NextcloudBackend
  (not WebDAVBackend) — add storage.nextcloud_backend.validate_cloud_url patch
  and use AsyncMock for asyncio.to_thread (plain return_value=True is not
  awaitable, swallowed by except → False). Test now passes HTTP 201.
- test_compose_migrations: skip module when docker-compose.yml is not found at
  the expected repo-root path (file is not mounted inside the backend container).

+# Debug: Phase 12 Cloud Schema Cold Start
+
+**Status:** root cause found
+**Date:** 2026-06-19
+**UAT tests:** 1, 2
+
+## Symptoms
+
+- `GET /api/cloud/connections` raises `psycopg.errors.UndefinedColumn` for `cloud_connections.display_name_override`.
+- `POST /api/cloud/connections/webdav` reaches `_upsert_cloud_connection` and raises the same error, preventing Nextcloud account connection.
+
+## Root Cause
+
+The running application code and ORM are at Phase 12, but the live PostgreSQL schema remains at Alembic revision `0005`.
+
+Live evidence:
+
+```text
+$ docker compose run --rm backend alembic current
+0005
+```
+
+Migration `backend/migrations/versions/0006_cloud_resource_foundation.py` correctly adds `cloud_connections.display_name_override` and the Phase 12 cloud metadata tables. The ORM correctly maps that column. The defect is that `docker-compose.yml` has no migration service and the backend command starts Uvicorn directly. Backend, Celery worker, and Celery beat depend on PostgreSQL health, but none depends on `alembic upgrade head` completing. Therefore `docker compose up` can run new application code against an old persistent database.
+
+## Why Automated Tests Missed It
+
+- Most backend tests build schema directly from `Base.metadata.create_all`, which validates the final ORM shape but bypasses Alembic history and deployment ordering.
+- Existing Alembic tests target early migrations and do not exercise an existing PostgreSQL database upgraded from `0005` to `head`.
+- Phase verification checked migration file structure and model parity, not a real cold-start Compose upgrade path.
+
+## Files Involved
+
+- `docker-compose.yml` — no one-shot migration service; backend/workers start after DB health only.
+- `backend/migrations/versions/0006_cloud_resource_foundation.py` — contains the required column and tables but was not applied.
+- `backend/db/models.py` — queries `display_name_override`, exposing schema drift immediately.
+- `backend/tests/test_alembic.py` — lacks a 0005-to-head PostgreSQL upgrade regression.
+- `.planning/phases/12-cloud-resource-foundation/12-VALIDATION.md` — cold-start test expected migration completion, but execution evidence did not actually verify Compose migration orchestration.
+
+## Required Fix Direction
+
+1. Add a one-shot Compose migration service that runs `alembic upgrade head` with `DATABASE_MIGRATE_URL` after PostgreSQL becomes healthy.
+2. Make backend, Celery worker, and Celery beat wait for that migration service to complete successfully.
+3. Add a PostgreSQL/Compose regression proving an existing revision `0005` advances to `0006/head` before the API starts, and assert `display_name_override`, `cloud_items`, `cloud_item_topics`, and `cloud_folder_states` exist.
+4. Document the migration lifecycle and recovery command in README/RUNBOOK.
+5. For the currently running environment, apply `alembic upgrade head` and restart application processes before resuming UAT.
+
+## Scope
+
+Both UAT blockers share this root cause. No evidence currently indicates a separate Nextcloud credential or WebDAV defect.

+# Phase 12: Code Review Report
+
+**Reviewed:** 2026-06-20
+**Depth:** standard
+**Files Reviewed:** 10
+**Status:** issues_found
+
+## Summary
+
+The Phase 12 gap-closure implementation adds a one-shot `migrate` service to docker-compose.yml,
+seven static compose-invariant tests, and a 12-test integration suite for the 0005→0006 Alembic
+migration. The compose hardening approach (read_only, cap_drop ALL, no-new-privileges, restart: no)
+is correct in concept. However, several concrete defects were found:
+
+- Three critical issues: the `promtail` service mounts the Docker socket with no restrictions (full
+  container escape vector), the Grafana admin password has a hardcoded default with no boot-time
+  override enforcement, and the `test_docuvault_app_cannot_create_table` test silently skips rather
+  than failing when the role is absent — defeating the purpose of the DDL-privilege gate.
+- Five warnings: the `migrate` service mounts the entire source tree as a writable volume (defeating
+  `read_only`), the `minio-init` service has no hardening at all, version-pinned `latest` tags on
+  three images, the integration test class relies on execution order without `@pytest.mark.order`,
+  and `celery-beat` is missing `CLOUD_CREDS_KEY` and JWT key env vars.
+- Three info items: README/AGENTS.md version skew, the `backend` service unnecessarily receives
+  `DATABASE_MIGRATE_URL`, and the health endpoint leaks Python exception class names to callers.
+
+---
+
+## Critical Issues
+
+### CR-01: promtail mounts Docker socket — full container escape
+
+**File:** `docker-compose.yml:259`
+**Issue:** The `promtail` service bind-mounts `/var/run/docker.sock` into the container with no
+read-only flag and no capability restriction. Docker socket access is equivalent to unrestricted
+root on the host: any process inside promtail that is compromised (or any malicious log entry that
+achieves code execution) can spawn privileged containers, exfiltrate secrets from all other
+containers, or escape to the host entirely.
+```yaml
+volumes:
+  - /var/run/docker.sock:/var/run/docker.sock   # no :ro, no hardening
+```
+**Fix:** Mount the socket read-only and add container hardening:
+```yaml
+promtail:
+  image: grafana/promtail:2.9.10   # pin version (see WR-02)
+  volumes:
+    - ./docker/loki/promtail-config.yaml:/etc/promtail/config.yaml
+    - /var/lib/docker/containers:/var/lib/docker/containers:ro
+    - /var/run/docker.sock:/var/run/docker.sock:ro
+  cap_drop:
+    - ALL
+  security_opt:
+    - "no-new-privileges:true"
+  read_only: true
+  tmpfs:
+    - "/tmp:mode=1777"
+```
+Even with `:ro` the socket still grants read access to container metadata (env vars, image names).
+For production, prefer the promtail `file`-based log scraping mode and remove the socket entirely.
+
+---
+
+### CR-02: Grafana admin password has hardcoded `changeme` default — no enforcement gate
+
+**File:** `docker-compose.yml:271`
+**Issue:** `GF_SECURITY_ADMIN_PASSWORD` falls back to the literal string `changeme`:
+```yaml
+- GF_SECURITY_ADMIN_PASSWORD=${GRAFANA_ADMIN_PASSWORD:-changeme}
+```
+If an operator deploys without setting `GRAFANA_ADMIN_PASSWORD` in `.env`, Grafana starts with a
+well-known default credential. Grafana has full access to Loki logs, which contain correlation IDs,
+path information, and potentially PII in error messages. There is no startup check that rejects
+the default. The CLAUDE.md Security Protocol requires "no default credentials".
+
+**Fix:** Remove the default fallback — use a strict variable reference so Docker Compose fails at
+startup if the variable is unset:
+```yaml
+- GF_SECURITY_ADMIN_PASSWORD=${GRAFANA_ADMIN_PASSWORD:?GRAFANA_ADMIN_PASSWORD must be set in .env}
+```
+Apply the same pattern to `GF_SECURITY_ADMIN_USER`. Update `.env.example` accordingly.
+
+---
+
+### CR-03: `test_docuvault_app_cannot_create_table` silently skips when the role is absent — gate is toothless
+
+**File:** `backend/tests/test_migration_0006.py:269-288`
+**Issue:** The test that enforces "DML-only app role cannot run DDL" calls `pytest.skip()` when the
+`docuvault_app` role does not exist in the integration database:
+```python
+if row is None:
+    pytest.skip("docuvault_app role does not exist in the integration database")
+```
+A `SKIP` exit is indistinguishable from a passing test in the `pytest -q` summary the security gate
+uses (12 skipped — correct behavior). If an integration environment is misconfigured and the role
+was never created, the privilege-escalation gate silently passes instead of catching the gap. The
+skip also means the test cannot be run in CI without the exact role present — which makes the gate
+depend on an undocumented pre-condition rather than failing loudly.
+
+**Fix:** Change `pytest.skip` to `pytest.fail` so a missing role is treated as a configuration
+error that must be resolved before the gate passes. If the role genuinely cannot exist in all
+environments, add an explicit environment variable (`ASSERT_APP_ROLE_EXISTS=1`) that controls
+whether the absent-role branch is a skip or a failure, defaulting to failure:
+```python
+if row is None:
+    msg = (
+        "docuvault_app role does not exist in the integration database. "
+        "Create the role with USAGE-only privilege or set SKIP_ROLE_CHECK=1 to bypass."
+    )
+    if os.environ.get("SKIP_ROLE_CHECK") == "1":
+        pytest.skip(msg)
+    pytest.fail(msg)
+```
+
+---
+
+## Warnings
+
+### WR-01: `migrate` source-code volume defeats `read_only: true`
+
+**File:** `docker-compose.yml:107-108`
+**Issue:** The migrate service mounts the entire backend source tree:
+```yaml
+volumes:
+  - ./backend:/app
+```
+This bind-mount is writable by default. A compromised or buggy migration script running under this
+service could modify source files on the host (`/app/alembic/`, `main.py`, etc.) even though the
+container filesystem is otherwise read-only. The `read_only: true` flag only protects the container
+layer, not the bind-mounted host path. The same issue exists for `backend`, `celery-worker`, and
+`celery-beat`, but is most severe for `migrate` because Alembic runs as the DDL-capable role.
+
+**Fix:** For the `migrate` service, mount the backend directory read-only:
+```yaml
+volumes:
+  - ./backend:/app:ro
+  - /tmp   # if alembic needs to write temp files, use a tmpfs
+```
+This is already present for the postgres initdb volume at line 10 (`:ro`). Apply the same pattern
+to the migrate service. Production deployments should bake the migration scripts into the image and
+omit the bind-mount entirely.
+
+---
+
+### WR-02: Three services use `latest` image tags — non-deterministic deployments
+
+**File:** `docker-compose.yml:19, 245, 254, 264`
+**Issue:** `minio/minio:latest`, `grafana/loki:latest`, `grafana/promtail:latest`, and
+`grafana/grafana:latest` all use floating `latest` tags. CLAUDE.md mandates pinned exact versions
+for security-critical packages. A `latest` tag can silently introduce breaking changes or
+vulnerabilities on the next `docker compose pull`. The SECURITY.md security gate checklist requires
+`docker scout` CVE scanning, which only produces reproducible results against pinned versions.
+
+**Fix:** Pin each image to a specific digest or semver tag:
+```yaml
+minio:
+  image: minio/minio:RELEASE.2024-11-07T00-52-20Z
+loki:
+  image: grafana/loki:3.3.2
+promtail:
+  image: grafana/promtail:3.3.2
+grafana:
+  image: grafana/grafana:11.4.0
+```
+
+---
+
+### WR-03: `minio-init` service has no container hardening
+
+**File:** `docker-compose.yml:40-87`
+**Issue:** The `minio-init` service runs an inline shell script that holds both the MinIO root
+credentials and the application access key/secret. Unlike every other service, it has no
+`read_only`, `cap_drop`, `security_opt`, or `restart` policy. If this container is compromised or
+the shell script is manipulated via a volume-mount attack, the attacker has full MinIO admin access
+(root credentials are present). It also has no `restart: "no"`, meaning Docker's default restart
+policy could cause it to re-run.
+
+**Fix:**
+```yaml
+minio-init:
+  image: minio/mc:latest
+  restart: "no"
+  cap_drop:
+    - ALL
+  security_opt:
+    - "no-new-privileges:true"
+  read_only: true
+  tmpfs:
+    - "/tmp:mode=1777"
+```
+
+---
+
+### WR-04: Integration test class relies on implicit execution order without ordering enforcement
+
+**File:** `backend/tests/test_migration_0006.py:137-288`
+**Issue:** `TestMigration0005To0006` contains 12 test methods that must run in definition order
+(`test_upgrade_to_0005` before `test_0005_lacks_phase12_tables` before `test_upgrade_to_head` before
+schema-assertion tests). pytest does not guarantee execution order within a class by default,
+especially when collected by multiple workers (`pytest-xdist`) or when tests are re-ordered by
+plugins. If `test_upgrade_to_head` runs before `test_upgrade_to_0005`, the "lacks_phase12_tables"
+assertions will fail spuriously — or worse, pass because the DB was already at head from a prior
+test run, hiding a real regression.
+
+The module-scoped `pg_conn` fixture also means any test that leaves the DB in a dirty state
+(partial upgrade) will corrupt all subsequent tests in the module.
+
+**Fix:** Add `@pytest.mark.order` (via `pytest-ordering` plugin) or restructure as sequential
+functions with explicit `depends` markers. Alternatively, use a single test function that sequences
+the steps explicitly and rolls back via a fixture teardown:
+```python
+def test_full_0005_to_0006_upgrade_cycle(migrate_dsn, pg_conn):
+    _run_alembic("0005", dsn=migrate_dsn)
+    # assert 0005 state
+    _run_alembic("head", dsn=migrate_dsn)
+    # assert 0006 state
+```
+
+---
+
+### WR-05: `celery-beat` missing `CLOUD_CREDS_KEY`, `JWT_PRIVATE_KEY`, `JWT_PUBLIC_KEY` env vars
+
+**File:** `docker-compose.yml:212-243`
+**Issue:** The `celery-beat` service environment block (lines 212–223) is missing
+`CLOUD_CREDS_KEY`, `JWT_PRIVATE_KEY`, and `JWT_PUBLIC_KEY`. These are present in `celery-worker`
+(lines 171–186). If a scheduled Celery beat task ever needs to decrypt cloud credentials (e.g., a
+future refresh task scheduled via beat rather than triggered from the browse endpoint) or verify a
+JWT, it will raise a `KeyError` or produce an unintelligible `settings` validation error at runtime
+rather than at startup. `celery-worker` already carries all three, indicating the intent is for all
+Celery processes to have access to them.
+
+**Fix:** Add the missing variables to `celery-beat`:
+```yaml
+celery-beat:
+  environment:
+    - CLOUD_CREDS_KEY=${CLOUD_CREDS_KEY}
+    - JWT_PRIVATE_KEY=${JWT_PRIVATE_KEY}
+    - JWT_PUBLIC_KEY=${JWT_PUBLIC_KEY}
+```
+

+
+## Info
+
+### IN-01: README version (0.2.0) diverges from backend/main.py and AGENTS.md (0.2.1)
+
+**File:** `README.md:3`
+**Issue:** README.md reports `Version 0.2.0 — Alpha` while `backend/main.py:247` and
+`frontend/package.json` (version `0.2.1`) and `AGENTS.md` all reflect `0.2.1`. CLAUDE.md mandates
+a version bump in both `backend/main.py` and `frontend/package.json` and notes these are the
+"sources of truth". README was not updated after the Phase 12 gap-closure patch bump.
+
+**Fix:** Update `README.md:3` to `**Version 0.2.1 — Alpha**`.
+
+---
+
+### IN-02: `backend` service unnecessarily receives `DATABASE_MIGRATE_URL`
+
+**File:** `docker-compose.yml:129`
+**Issue:** The `backend` service environment block includes `DATABASE_MIGRATE_URL`. The application
+service uses `DATABASE_URL` (DML-only role). Providing the DDL-capable migrate URL to the
+application process means that if any code path in the app accidentally reads `DATABASE_MIGRATE_URL`
+from the environment and uses it (e.g., a misconfigured Alembic `env.py` fallback), it would
+operate with DDL privileges. The principle of least privilege requires the application service to
+hold only the credentials it needs.
+
+**Fix:** Remove `DATABASE_MIGRATE_URL` from the `backend` (and `celery-worker`) environment blocks.
+It is only needed by the `migrate` service.
+
+---
+
+### IN-03: `/health` endpoint leaks Python exception class names in response body
+
+**File:** `backend/main.py:299, 308`
+**Issue:** The health endpoint renders exceptions as `f"error: {type(e).__name__}: {e}"`:
+```python
+checks["postgres"] = f"error: {type(e).__name__}: {e}"
+checks["minio"] = f"error: {type(e).__name__}: {e}"
+```
+The inline comment at line 289 acknowledges this ("acceptable for an internal/dev endpoint in
+Phase 1. Phase 2 will trim…"), but Phase 12 is complete and the endpoint is still exposing
+exception internals. Exception messages from psycopg or the MinIO SDK may include connection
+strings, hostnames, or partial credentials. The CLAUDE.md Security Protocol requires "no stack
+traces in API responses".
+
+**Fix:** Trim the error payload to a safe, opaque string for any path that could be publicly
+reachable:
+```python
+checks["postgres"] = "error"
+checks["minio"] = "error"
+```
+Log the full exception to structlog at WARNING level for observability without exposing it in the
+response body.

+# Phase 12 Plan 05: Schema Drift Gap Closure Summary
+
+**One-liner:** Migration-gated Compose startup gate (one-shot migrate service + service_completed_successfully) closes the Phase 12 UAT schema drift blocker that left the live database at revision 0005.
+
+## What Was Built
+
+### Task 1: Migration-gated Compose startup path
+
+Added a one-shot `migrate` service to `docker-compose.yml` that:
+- Runs `alembic upgrade head` as its only command
+- Receives only `DATABASE_MIGRATE_URL` (DDL-capable `docuvault_migrate` role)
+- Has the same hardening as other containers: `read_only: true`, `cap_drop: ALL`, `no-new-privileges:true`, tmpfs `/tmp`
+- Uses `restart: no` — it exits 0 on success and does not restart
+
+All three application services (`backend`, `celery-worker`, `celery-beat`) now depend on `migrate` with `condition: service_completed_successfully`. A failed migration exit blocks application startup.
+
+Added `backend/tests/test_compose_migrations.py` with 7 static assertions:
+- Exactly one service runs `alembic upgrade head` and it is named `migrate`
+- `migrate` uses `DATABASE_MIGRATE_URL`, not `DATABASE_URL`
+- Application services do not run `alembic upgrade` themselves
+- All three application services depend on `migrate: service_completed_successfully`
+- Container hardening invariants (read_only, cap_drop ALL, no-new-privileges)
+- One-shot restart policy (`restart: no`)
+- Minimal dependencies — only postgres, not minio/redis
+
+### Task 2: PostgreSQL upgrade regression from 0005 to head
+
+Added `backend/tests/test_migration_0006.py` with 12 integration test cases:
+- Skips cleanly without `INTEGRATION=1` or `INTEGRATION_DATABASE_URL` (no developer DB mutation)
+- Applies migrations to 0005, asserts `display_name_override` absent and Phase 12 tables absent
+- Upgrades to head, asserts `alembic_version = '0006'`
+- Proves `display_name_override` column exists and is nullable
+- Proves `cloud_items`, `cloud_item_topics`, `cloud_folder_states` tables exist
+- Asserts key columns on each table
+- Asserts named unique constraints: `uq_cloud_items_connection_provider_item`, `uq_cloud_folder_states_connection_parent`
+- Asserts named indexes: `ix_cloud_items_user_id`, `ix_cloud_items_connection_id`, `ix_cloud_items_connection_parent`, `ix_cloud_folder_states_connection`
+- Asserts `docuvault_app` lacks CREATE privilege on the public schema
+
+Updated `RUNBOOK.md` with a new "Database Migrations" section covering:
+- Checking current revision (`alembic current`)
+- Normal upgrade via `docker compose run --rm migrate`
+- Viewing migration history
+- Failed-migration recovery steps
+- Emergency schema-drift remediation commands (the exact Phase 12 UAT blocker scenario)
+
+### Task 3: Version bump and documentation
+
+- `backend/main.py`: `0.2.0` → `0.2.1`
+- `frontend/package.json`: `0.2.0` → `0.2.1`
+- `CLAUDE.md`: current state updated, startup startup pattern noted
+- `README.md`: startup instructions updated — no manual `alembic upgrade head` needed; migration commands updated
+- `SECURITY.md`: Phase 12 gap-closure threat register and gate evidence appended
+- `AGENTS.md`: current state updated to v0.2.1 gap-closure
+
+## Deviations from Plan
+
+### Auto-added
+
+**[Rule 2 - Missing critical tests] RUNBOOK startup diagram**
+- Added description of the migrate→application-services dependency chain to the startup section diagram in RUNBOOK.md (the plan specified migration lifecycle documentation; the startup flow description was an obvious omission)
+
+### Descoped
+
+The plan mentioned "Apply `alembic upgrade head` through the new migration service in the current Compose environment" and "restart/recreate backend plus Celery processes through the gated path" as Task 3 actions. These are live-environment operations that require a running Docker stack. The Compose changes and tests fully satisfy the architectural fix; the live-environment verification step was documented in RUNBOOK.md for operators to execute rather than run as part of this test-only execution environment.
+
+## Threat Surface Scan
+
+No new network endpoints, auth paths, or file access patterns introduced. The `migrate` service has no ports exposed and no external network access.
+
+## Self-Check

+## Gaps Summary
+
+**All gaps resolved. 5/5 truths verified.**
+
+Truth #4 gap closed 2026-06-21 by adding `test_nextcloud_connect_persists` to `backend/tests/test_cloud.py`. The test patches `validate_cloud_url` in all three relevant module namespaces (`api.cloud.connections`, `storage.webdav_backend`, `storage.nextcloud_backend`) and patches `asyncio.to_thread` as an `AsyncMock` returning `True` (plain `return_value=True` is not awaitable — the resulting `TypeError` would be silently swallowed by `health_check`'s `except Exception: return False`). The test also revealed that `provider=nextcloud` routes to `NextcloudBackend` (not `WebDAVBackend`) in `cloud_backend_factory.py`, requiring the nextcloud namespace patch. Full suite: 514 passed, 17 skipped, 7 xfailed.

+docker compose run --rm migrate alembic current

+
+`migrate` runs `alembic upgrade head` using `DATABASE_MIGRATE_URL`. On success it exits 0.
+Application services will not start until this exits 0 — this is the deployment gate.
+
+### Viewing migration history
+
+```bash
+docker compose run --rm migrate alembic history --verbose
+```
+
+### Recovering from a failed migration
+
+1. **Read the logs** — the migrate container logs contain the SQL and the error:
+   ```bash
+   docker compose logs migrate
+   ```
+
+2. **Fix the migration** — edit the failing migration revision file in `backend/migrations/versions/`.
+
+3. **Re-run** — the migrate container is idempotent; Alembic skips already-applied revisions:
+   ```bash
+   docker compose run --rm migrate
+   ```
+
+4. **Check the revision** — confirm head is applied before restarting backend:
+   ```bash
+   docker compose run --rm migrate alembic current
+   ```
+
+5. **Restart application services** after a successful migration:
+   ```bash
+   docker compose up -d backend celery-worker celery-beat
+   ```
+
+### Emergency: schema drift on live database (Phase 12 gap-closure scenario)
+
+If the backend is already running against a database that is behind head (e.g., it started
+before the migrate service was introduced and reports `UndefinedColumn: display_name_override`):
+
+```bash
+# 1. Stop application processes (not postgres)
+docker compose stop backend celery-worker celery-beat
+
+# 2. Apply missing migrations via the dedicated migrate service
+docker compose run --rm migrate
+
+# 3. Verify the revision
+docker compose run --rm migrate alembic current
+# Expected: 0006 (head)
