M7: portfolio polish and final acceptance

Automated migrations on container startup (backend/entrypoint.sh), scripted n8n workflow activation (make n8n-setup), Playwright E2E test covering the full 9-step demo script (verified passing against the live stack, including the previously-unverified 360px responsive layout), evidence screenshots of all main pages, architecture diagram, and artifacts/evidence/final-summary.md with commit/commands/test counts/RAGcore and n8n evidence/MCP sample calls/known limitations/portfolio wording. Verified the complete clean-checkout path from a genuinely wiped-volumes state: automatic migrations, seed, 66 backend tests passing, and a live S1 return round-tripped through a freshly-activated n8n instance. Added .gitattributes to force LF line endings on shell scripts, preventing a real cross-platform breakage of entrypoint.sh's shebang.

 ## Exact next action
 
-Start M7 (portfolio polish and final acceptance): read `docs/06-ui-ux.md`, `docs/14-testing-and-acceptance.md`, `docs/16-portfolio-case-study.md`. Work through `docs/14-testing-and-acceptance.md`'s clean-checkout acceptance list item by item from a genuinely fresh checkout (new clone, `cp .env.example .env`, documented bootstrap commands only) rather than this session's already-running/already-seeded stack — several manual one-time steps accumulated this session (n8n owner setup + workflow import/publish/restart, see M4 notes) that must either be scripted into the bootstrap or written up precisely in `docs/17-runbook.md`, since a true clean checkout won't have them done yet. Also needed: Playwright end-to-end test covering the full documented 5-minute demo script (login → dashboard → S1 return → S2 merge → S4 overlap already-visible → S6 knowledge question → audit → responsive nav at 360px — the ≤360px layout was flagged as visually unverified back in M1 and should finally be checked here), screenshots of the seven main pages, an architecture diagram, `artifacts/evidence/final-summary.md` per the doc's exact required contents (commit/tag, commands, test counts — currently 66 backend tests across M0–M6 — screenshots, RAGcore success/unavailable evidence, n8n success/retry evidence, MCP sample calls, known limitations, truthful portfolio wording), and a final pass removing any rough edges/placeholders across the UI.
+### M7 — Portfolio polish and final acceptance
+- **Automated clean-checkout migrations**: `backend/entrypoint.sh` now runs `alembic upgrade head` before starting uvicorn (Dockerfile `CMD` changed from `uvicorn ...` to `./entrypoint.sh`). Verified with a true `docker compose down -v` (all volumes wiped) → `docker compose up --build -d` → all 11 tables present, `/health` and web both green, all 66 backend tests pass, with zero manual migration step.
+- **n8n one-time setup scripted where it can be**: `make n8n-setup` runs the import/publish/restart sequence (previously three manual commands discovered ad hoc in M4). The owner-account creation itself cannot be scripted safely (it's an interactive one-time step in n8n 2.x's own onboarding, not a MobilityOps concern) — documented precisely in the rewritten `docs/17-runbook.md`, including the exact URL and that no email verification is required. Re-ran this full sequence from the wiped-volumes state this session and confirmed the S1 return → outbox → live n8n → callback → `succeeded` round trip works on a genuinely clean checkout, not just the already-provisioned stack from M0–M6.
+- **Playwright E2E** (`frontend/e2e/demo.spec.ts`, `frontend/playwright.config.ts`): one test automating the full 9-step documented demo script end-to-end against the live stack — login, dashboard metrics, open `BK-DEMO-RETURN`, register an odometer-regression return (S1), verify the quality issue + queued automation event, merge the duplicate-customer scenario (S2), ask the damage question and verify both expected source citations (S6), inspect audit entries, and verify responsive nav + no horizontal overflow at 360px width. **Passing.** This also resolves the "≤360px layout visually unverified" gap flagged back in M1 — verified both by this test's overflow assertion and by the `9-mobile-dashboard.png` screenshot (nav wraps into rows, metric tiles collapse to a 2-column grid, no horizontal scroll).
+- Added `frontend/e2e/_capture-screenshots.spec.ts` as evidence-generation tooling (underscore-prefixed, excluded from the default `playwright test` / `make e2e` run via `testIgnore` in the config — it calls `demo/reset`, which a real regression test shouldn't do as a side effect). Captured all 9 screenshots into `artifacts/evidence/screenshots/`.
+- Wrote `artifacts/evidence/architecture.md` (mermaid, as-built — distinguishes verified-live components from implemented-but-never-reached-a-real-instance ones, i.e. RAGcore and the MCP Hub) and `artifacts/evidence/final-summary.md` (commit, exact commands, test counts, screenshot index, RAGcore success/unavailable evidence — including a live-demonstrated unavailable case against an unreachable host, not just the unit test — n8n success/retry evidence, MCP sample calls, known limitations, truthful portfolio wording per `docs/16-portfolio-case-study.md`'s template).
+- Updated `README.md` (dropped stale "minimal bootable scaffold, not the finished application" wording and the old two-line quickstart in favor of `make demo` + a pointer to the runbook) and `docs/17-runbook.md` (full rewrite: exact bootstrap, n8n one-time setup, verification commands, required operational checks, recovery expectations).
+- Final placeholder/dead-UI sweep: `grep`'d the full `frontend/src` and `backend/app` trees for scaffold/TODO/FIXME/"must be replaced" markers — none found. `FILE_INDEX.md` was left as-is; it's the original build-pack's archive-completeness manifest (a historical snapshot), not a living index that needs to track every file added since — updating it would misrepresent what it's for.
+- Commands run and verified from this checkout (this milestone, cumulative across the whole build):
+  - `docker compose run --rm api pytest -q` — **66 passed**, ruff clean.
+  - `cd frontend && npm run build` — clean.
+  - `cd frontend && npx playwright test` — **1 passed** (full demo script, live stack).
+  - Full clean-checkout drill: `docker compose down -v` → `docker compose up --build -d` → `docker compose exec api python -m app.cli seed --reset` → `docker compose run --rm api pytest -q` (66 passed) → n8n owner setup + `make n8n-setup` → live S1 return round-tripped through the real n8n instance to `succeeded`.
+
+## Definition of done
+
+All eight milestones (M0–M7) are complete. `docs/14-testing-and-acceptance.md`'s clean-checkout acceptance list has been walked item by item against a genuinely wiped-volumes checkout this session (see M7 notes above), and `artifacts/evidence/final-summary.md` contains the final evidence summary this file's own instructions (`CLAUDE.md`) require. The two items not fully closed — a live RAGcore instance and a live ITWorx MCP Hub instance — were never reachable in this environment; both integrations are implemented, unit/contract-tested, and documented as such rather than claimed as verified.

+## Component responsibility (unchanged from `docs/03-architecture.md`)
+
+| Component | Owns |
+|---|---|
+| MobilityOps | vehicles, customers, bookings, inspections, data-quality issues, audit, outbox/delivery state |
+| RAGcore | procedure retrieval and grounded answers (demo provider substitutes locally) |
+| ITWorx MCP Hub | MCP transport, tool publication, central tool-call audit |
+| n8n | post-commit secondary orchestration only — never the source of truth for vehicle state |
+
+## Reliability boundaries verified in this build
+
+1. **Return commits atomically with its outbox event** — `app/services/returns.py`, one
+   transaction; verified by `test_concurrent_returns_only_one_succeeds` (real Postgres row
+   locking, not mocked).
+2. **Outbox delivery is at-least-once, idempotent by event ID** — verified live: the n8n
+   callback checks for an existing `AuditEvent` by event ID before recording a second time.
+3. **RAGcore failure disables knowledge answers only** — `RAGcoreKnowledgeProvider` degrades
+   to `unavailable`; the rest of the app is unaffected because the knowledge router is the
+   only consumer.
+4. **MCP Hub failure does not affect the web application** — the four MCP provider
+   endpoints are a separate authenticated surface (`X-Service-Token`), invisible to the
+   browser-facing API/UI.
+5. **n8n failure leaves events pending with bounded retries** — verified live: a seeded
+   `failed` event, retried through the UI, was picked up by the background dispatcher and
+   delivered through the real n8n instance within one poll cycle.

+
+One-time n8n setup (see `docs/17-runbook.md` for full detail — this cannot be scripted
+end-to-end because it requires a one-time owner account created through n8n's web UI):

+## RAGcore evidence
+
+**Success (demo provider, the one actually satisfying acceptance in this environment)** —
+S6 question against the real `/api/v1/knowledge/questions` endpoint:
+
+```json
+{
+  "answer": "Per \"Vehicle return procedure\" (v2.0), section \"1. Register the return\": Open the active booking and record the ending odometer, fuel level, cleanliness, visible damage, technical warnings and relevant notes.",
+  "evidence_state": "grounded",
+  "sources": [
+    {"document_id": "vehicle-return-procedure", "title": "Vehicle return procedure", "version": "2.0", "section": "1. Register the return", "excerpt": "..."},
+    {"document_id": "vehicle-return-procedure", "title": "Vehicle return procedure", "version": "2.0", "section": "3. Determine next state", "excerpt": "..."},
+    {"document_id": "damage-procedure", "title": "Damage handling procedure", "version": "1.3", "section": "1. Immediate actions", "excerpt": "..."}
+  ],
+  "provider": "demo",
+  "correlation_id": "b50094b7-1c84-4e39-9055-1dc03e8fd1f8"
+}
+```
+
+**Unavailable (RAGcore adapter, live-demonstrated against an unreachable host)** —
+`KNOWLEDGE_PROVIDER=ragcore`, `RAGCORE_BASE_URL=http://ragcore-not-reachable:9999`:
+
+```
+health: {'provider': 'ragcore', 'available': False, 'detail': 'RAGcore unavailable: ConnectError: ...', 'document_count': 0}
+ask:    {'answer': '', 'evidence_state': 'unavailable', 'sources': [], 'provider': 'ragcore', 'correlation_id': 'demo-correlation'}
+```
+
+No live RAGcore instance was reachable in this environment, so the adapter's actual
+request/response contract against a real RAGcore is unverified beyond this
+degrade-safely behavior — see `contracts/ragcore-contract-assumptions.md` and
+`PROJECT_STATE.md`'s M5 notes.
+
+## n8n evidence
+
+**Success** — a real return registered on `BK-DEMO-RETURN`, delivered through the actual
+n8n instance (not mocked), confirmed via `GET /api/v1/workflows`:
+
+```json
+{"event_id": "aa5dfeee-90ca-452a-bdd1-0a0b6d3dd63f", "event_type": "vehicle.returned.v1", "aggregate_ref": "BK-DEMO-RETURN", "status": "succeeded", "attempts": 2, "last_error": null}
+```
+
+(`attempts: 2` because the first delivery attempt landed while n8n was mid-restart from
+the one-time workflow-activation step — the dispatcher's backoff-and-retry handled it
+without any manual intervention, which is itself evidence of the retry behavior working.)
+
+**Retry (S5 scenario)** — seeded `BK-H-0020` (event `00000000-...-0020`), initially
+`failed` after 3 attempts with `"Synthetic connection timeout to n8n"`:
+
+1. Before: `{"status": "failed", "attempts": 3, "last_error": "Synthetic connection timeout to n8n"}`
+2. Operations Manager clicks Retry on `/automation`.
+3. Within one ~3s dispatcher poll cycle, delivered through the live n8n instance.
+4. After: `{"status": "succeeded", "attempts": 4, "last_error": null}`
+
+## MCP tool sample calls
+
+All four provider endpoints, authenticated with `X-Service-Token`:
+
+```
+$ curl -H "X-Service-Token: <token>" http://localhost:8128/api/v1/integrations/mcp/operations-summary
+{"tenant":"northstar-mobility-demo","metrics":{"available":21,"rented":11,"cleaning":6,"maintenance":5,"blocked":7,"open_quality_issues":22,"pending_or_failed_workflows":1}}

+{"answer":"Per \"Vehicle return procedure\" ...","evidence_state":"grounded","sources":[...2 items...],"provider":"demo",...}
+```
+
+Auth verified: missing header → `422`; wrong token → `401`. All four calls confirmed
+recorded in `GET /api/v1/audit?action=mcp_tool_request` with `actor_type: "service"`.
+
+No live ITWorx MCP Hub instance was reachable in this environment — these are direct
+calls to MobilityOps's own provider endpoints, not a Hub round trip.
+
+## Known PoC limitations
+
+- **RAGcore and ITWorx MCP Hub were never reachable in this build environment.** Both
+  integrations are implemented against best-effort/documented contracts and are
+  unit/contract-tested (including their failure-degradation paths), but neither was
+  verified against a real counterpart service. The demo `KnowledgeProvider` is what
+  actually satisfies the knowledge-assistant acceptance criteria here.
+- **n8n requires a one-time manual owner-account setup** per fresh environment
+  (`docker compose down -v` wipes it) — this is a property of the n8n 2.x image itself
+  (`N8N_BASIC_AUTH_ACTIVE` no longer gates the UI), not something MobilityOps can bypass.
+  Documented precisely in `docs/17-runbook.md`; the workflow import/activation itself
+  *is* scripted (`make n8n-setup`).
+- **Inspection public refs are a simple `count+1` sequence**, not gap-safe under true
+  concurrent writers — acceptable for this single-tenant demo, would need a DB sequence
+  for a multi-writer production system.
+- **The five data-quality rules use simplified idempotency** — `(rule_type, entity_type,
+  entity_id)` while open, rather than the doc's literal evidence-fingerprint scheme — see
+  `PROJECT_STATE.md`'s M3 notes for the reasoning (the fingerprint scheme would have let
+  the scan double-report issues already present in the seeded CSV).
+- **No production authentication** — demo login is an HMAC-signed session cookie tied to
+  two fixed seeded users, appropriate for a PoC, not a real identity provider.
+
+## Portfolio wording (truthful)
+
+MobilityOps is a working proof of concept, not a production system and not deployed for
+any real company. All customers, vehicles, bookings, and documents are synthetic
+(deterministically generated). The application logic it demonstrates is real: a
+transactional vehicle-return workflow with idempotency and concurrency control tested
+against real concurrent database transactions; five explainable, deterministic
+data-quality rules with a working customer-merge UI; a background outbox dispatcher
+verified end-to-end against a real n8n instance including failure/retry; a
+TF-IDF-weighted extractive knowledge assistant that never fabricates answers; and four
+read-only, audited, service-authenticated integration endpoints. RAGcore and the ITWorx
+MCP Hub integrations are implemented and tested in isolation but were not verified
+against live instances of those systems in this environment.

+## n8n automation (one-time per environment)
+
+The n8n image used here (n8nio/n8n:latest, 2.x) requires an owner account before any
+workflow — including webhook registration — works reliably; `N8N_BASIC_AUTH_ACTIVE` no
+longer gates this. This is a one-time step per fresh `docker compose down -v`:
+
+1. Open `http://localhost:5678/setup` and create an owner account (any email/password
+   meeting the 8+ characters / 1 number / 1 capital rule — no email verification is
+   required). Skip the optional survey/license-key dialogs that follow.
+2. Import and activate the return-processing workflow:
+
+   ```bash
+   make n8n-setup
+   ```
+
+   which runs:
+
+   ```bash
+   docker compose exec n8n n8n import:workflow --input=//imports/mobilityops-return-processing.json
+   docker compose exec n8n n8n publish:workflow --id=mobilityops-return-processing
+   docker compose restart n8n
+   ```
+
+   (`n8n import:workflow` always leaves the workflow deactivated regardless of its
+   `"active"` field; `publish:workflow` + a restart is what actually activates it.)
+
+Verify the full round trip:
+
+```bash
+# after logging in and registering any return via the UI or API
+curl -b cookies.txt http://localhost:8128/api/v1/workflows | grep succeeded
+```
+
+A failed/offline n8n does not roll back the return — the outbox event simply stays
+`pending`/`failed` and is safely retryable from the Automation page.

+  routes with and without a valid `X-Service-Token` — see
+  `artifacts/evidence/final-summary.md` for sample calls);
+- deterministic demo reset (`POST /api/v1/demo/reset` as Operations Manager, or `make seed`).
 
 ## Recovery expectations
 
-- database restart: application reconnects;
-- n8n outage: events remain pending and retryable;
-- RAGcore outage: knowledge shows unavailable, operations continue;
-- MCP Hub outage: web application unaffected;
-- failed demo experiment: Operations Manager reset restores the seed.
+- database restart: application reconnects (SQLAlchemy connection pool, `pool_pre_ping=True`);
+- n8n outage: events remain `pending` and are retried with exponential backoff, then
+  `failed` after 5 attempts and safely retryable from `/automation`;
+- RAGcore outage: `/knowledge` shows `unavailable`, all operational pages continue working;
+- MCP Hub outage: the web application is unaffected — MCP endpoints are a separate,
+  independently-authenticated API surface;
+- failed demo experiment: Operations Manager reset (`POST /api/v1/demo/reset`) restores
+  the deterministic seed, including all named S1–S6 demo scenarios.
