-# Binding instructions for Claude
-
-## Operating mode
-
-Work autonomously. Do not ask the user product, architecture, naming, UI, scope or implementation questions already answered in this repository. Record a reasonable assumption in an ADR only when a genuine gap blocks implementation.
-
-Use normal or medium reasoning for routine work. Reserve high reasoning for an actual cross-service design conflict or a persistent failure after evidence-driven debugging.
-
-Continue from milestone to milestone until every acceptance criterion is satisfied. Do not stop merely because one milestone is complete.
-
-## Token and tool efficiency
-
-1. Read `START_HERE.md`, this file, `PROJECT_STATE.md` and `docs/15-build-plan.md` first.
-2. Read only the milestone-specific documents named in the build plan.
-3. Do not repeatedly reread all documentation.
-4. Keep explanations terse; spend effort on implementation and validation.
-5. Update `PROJECT_STATE.md` after each milestone with decisions, commands, evidence and the exact next action.
-6. Prefer focused file inspection and targeted tests over broad repository scans.
-7. Do not generate large speculative documents after implementation starts.
-
-## Scope discipline
-
-- Build the locked PoC only.
-- Do not add accounting, payments, public reservations, a generic CRM, inventory, HR, a second RAG stack, a separate MCP server or autonomous write actions.
-- Do not modify the RAGcore or ITWorx MCP Hub repositories. Integrate only through documented contracts and configurable adapters.
-- Keep critical business rules in MobilityOps code, not in n8n or prompts.
-- No direct MCP Hub or RAGcore access to the MobilityOps database.
-
-## Product quality
-
-- No dead buttons, empty routes, unexplained placeholders or hardcoded dashboard metrics.
-- Every visible number must derive from persisted data.
-- All important state changes must be audited.
-- AI must never invent an answer when RAGcore is unavailable or returns insufficient evidence.
-- Vehicle returns must commit locally even when n8n is unavailable; orchestration becomes pending and retryable.
-- External dependencies require timeouts, bounded retries, health state and graceful degradation.
-- Demo data must be clearly labelled synthetic.
-
-## Engineering rules
-
-- Backend: Python, FastAPI, SQLAlchemy 2, Alembic, PostgreSQL.
-- Frontend: React, TypeScript, Vite, accessible responsive UI.
-- Validation: Pydantic at API boundaries and database constraints for invariants.
-- Use UUID primary keys internally and stable human-readable public references.
-- Store UTC timestamps; render Europe/Brussels in the UI.
-- API paths start with `/api/v1`.
-- Use an outbox record for reliable post-commit n8n delivery.
-- Tests must cover domain rules, API contracts and the five-minute Playwright demo.
-- Generate and commit dependency lockfiles.
-
-## Git workflow
-
-Create one coherent commit per milestone after its validation passes. Suggested message format:
-
-`M1: implement operational core`
-
-Never rewrite already accepted milestone history unless necessary to fix a regression.
-
-## Definition of done
-
-The project is done only when `docs/14-testing-and-acceptance.md` passes from a clean checkout and `PROJECT_STATE.md` contains the final evidence summary.

+# Contributing
+
+MobilityOps contributions must preserve fleet-data privacy, deterministic demo behaviour and the fail-closed integration boundaries documented in `SECURITY.md`.
+
+- use synthetic vehicles, customers, bookings, returns, telematics events and identity claims in tests and screenshots;
+- never commit production databases, exports, operator inventories, private service URLs, tokens, backups or generated browser evidence;
+- keep external integrations configurable through environment variables or explicit deployment configuration;
+- document new personal-data fields, retention, authorization, audit and deletion/export behaviour;
+- add negative tests for authentication, authorization, duplicate handling, webhook validation, path containment and stale/unavailable providers;
+- review dependencies, images and browser assets for provenance and redistribution rights.
+
+Run the relevant backend, frontend, migration, integration, Compose and managed-validation gates before review. Security-sensitive findings belong through the private process in `SECURITY.md`.

-First read `START_HERE.md`, `CLAUDE.md`, `PROJECT_STATE.md` and `docs/15-build-plan.md`. Treat the repository specifications and contracts as binding. Do not ask me questions that the files already answer, do not broaden the PoC, and do not stop after a milestone.
-
-Implement the milestones in order. For each milestone:
-
-1. read only the documents listed for that milestone;
-2. implement the smallest complete solution;
-3. run the specified validation plus relevant regression tests;
-4. fix failures using evidence rather than guesses;
-5. update `PROJECT_STATE.md` with concise evidence and the exact next step;
-6. commit the completed milestone;
-7. continue immediately.
-
-MobilityOps owns operational data and business rules. RAGcore owns retrieval and grounded answers. ITWorx MCP Hub owns MCP publication and policy. n8n only orchestrates post-commit workflows. Use configurable adapters and working degraded modes so the core demo remains usable when any external service is absent.
-
-The finished PoC must be reproducible from a clean checkout, have no dead UI, use deterministic synthetic data, support the documented five-minute demo, and satisfy every criterion in `docs/14-testing-and-acceptance.md`.

-# MobilityOps — Claude build pack
-
-MobilityOps is a deliberately scoped, working proof of concept for a fictitious Belgian mobility-rental company. It demonstrates how operational data, workflow automation, data-quality review, a central RAG service and a central MCP hub can work together without pretending to be a full ERP.
-
-## Use this pack efficiently
-
-1. Extract this archive into a new repository.
-2. Open the repository in Claude Code.
-3. Paste the contents of `MASTER_BUILD_PROMPT.md` once.
-4. Let Claude continue autonomously through the milestones in `docs/15-build-plan.md`.
-5. Only intervene if the environment itself is unavailable or credentials for an external service are required.
-
-Claude must use `PROJECT_STATE.md` as its compact memory between sessions. Do not restate the full project in later prompts.
-
-## What is included
-
-- locked product scope and non-goals;
-- architecture and domain decisions;
-- API and event contracts;
-- realistic deterministic synthetic seed data;
-- eleven fictitious procedures for RAGcore (nl-BE, en-GB, fr-BE);
-- an initial n8n workflow export;
-- MCP tool definitions for ITWorx MCP Hub;
-- a minimal bootable frontend/API scaffold;
-- acceptance criteria and a five-minute demo script;
-- a master prompt optimized for one autonomous build run.
-
-## Core responsibilities
-
-| Component | Responsibility |
-|---|---|
-| MobilityOps | Operational data, business rules, UI, audit and data-quality review |
-| RAGcore | Document ingestion, retrieval and source-grounded answers |
-| ITWorx MCP Hub | Controlled AI access to MobilityOps tools and MobilityOps knowledge |
-| n8n | Cross-system orchestration after committed domain events |
-
-## Build principle
-
-Finish a small vertical slice completely. No placeholder pages, fake buttons, invented production claims or scope expansion.

-## Branches and commits
-
-- **Gitea repository**: `ssh://git@192.168.10.150:222/Jens/MobilityOps.git` (browsable at
-  `http://192.168.10.150:3000/Jens/MobilityOps`)
-- **Branch**: `feat/mobilityops-functional-completion` (no new branch created; no merge
-  to `main`; no rebase/reset/squash/force-push; full git history preserved, as required)
-- **Start commit** (functional-completion baseline, already accepted):
-  `e0c7ed60112510687627d20a957af91c8b9db7f8`
-- **Final commit**: `4a268c73515dc4f1d56c1aa2f231714654bffbb8` — verified via
-  `git rev-parse HEAD` on `feat/mobilityops-functional-completion` and confirmed to match
-  `/mnt/user/appdata/mobilityops/.deploy/source-revision` on the Unraid server exactly.
-  (This corrects a self-reference gap in the immediately preceding pair of commits, which
-  necessarily could not know their own hash at the time they were written; this is now
-  the single, unambiguous, verified reference. The repository's primary branch is
-  `master`, not `main` — no branch named `main` exists in this repository.)
-- **Live URL**: `http://192.168.10.150:1236`
-
-## Demo organisation and context
-
-**Northstar Mobility** — a fictitious Belgian camper/van rental company (~50 vehicles,
-one main location, rental team, an Operations Manager, a small workshop). This name was
-already a locked internal decision (`ragcore_tenant: northstar-mobility-demo`,
-`PROJECT_STATE.md`'s "Locked decisions") before this work — this pass surfaces it in the
-UI rather than inventing it. Full concept: `docs/demo-release/demo-concept.md`.
-
-## Roles
-
-- **Operations Manager** — full access: data-quality resolution, workflow retries, audit
-  trail, demo reset, the Demo Guide.
-- **Rental Employee** — scoped access: bookings, returns, fleet, knowledge assistant.
-
-Both are reachable from the login screen with no password.
-
-## Demo Guide
-
-An 8-step, sessionStorage-persisted guided tour (Operations-Manager-only, since every
-step requires that role). Full design: `docs/demo-release/demo-guide.md`. Steps: (1)
-understand operational state, (2) open the booking needing attention, (3) process the
-odometer-anomaly return, (4) handle the created data-quality issue, (5) merge the
-duplicate customer, (6) ask the knowledge assistant, (7) check automation + audit, (8)
-review real vs. synthetic vs. not-connected.
-
-## Scenarios (all 5, full detail in `docs/demo-release/demo-scenarios.md`)
-
-| # | Scenario | Fixed records | Role |
-|---|---|---|---|
-| 1 | Odometer regression on return | `BK-DEMO-RETURN` / `MO-024` | Either |
-| 2 | Possible duplicate customer | `CUS-0012` / `CUS-0178` / `DQ-DEMO-DUPLICATE` | OM |
-| 3 | Overlapping bookings | `MO-016` / `BK-DEMO-OVERLAP-A/B` / `DQ-DEMO-OVERLAP` | OM |
-| 4 | Failed automation, retried | outbox event `...020` / `BK-H-0020` | OM |
-| 5 | Grounded procedure question | (no fixed record; suggested questions) | Either |
-
-`GET /api/v1/demo/manifest`'s `scenarios` array derives `ready`/`blocked_reason` from the
-live underlying records, never hardcoded — confirmed via `backend/tests/
-test_demo_manifest.py` (`test_demo_manifest_scenarios_ready_after_fresh_reset`) and
-live-checked after every reset throughout this work.
-
-## Seed strategy and date-anchoring
-
-`seed/generate_seed.py --anchor 2026-08-01 --seed 20260801` produces deterministic CSVs
-with absolute timestamps authored against a fixed anchor. `backend/app/seed_loader.py`
-shifts every seeded datetime by `(real today − authored anchor)` on every seed/reset, so
-"today"/"near-future"/"currently overlapping" scenarios stay true to the actual reset
-moment instead of decaying. This fixed a real, confirmed bug (`BK-DEMO-RETURN` was found
-sitting 2 days in the past before this fix). Full detail: `docs/demo-release/demo-data.md`.
-
-## Reset strategy
-
-`POST /api/v1/demo/reset` (Operations Manager only, gated by `DEMO_ALLOW_RESET`) clears
-MobilityOps's own tables, reseeds with a fresh date anchor, re-runs the data-quality scan,
-and runs a server-side scenario-integrity check (`scenario_integrity_report()`) recorded
-in both the response and the `demo_reset` audit event. Reachable from the sidebar, the
-Demo Guide, and the About page. Never touches shared n8n/RAGcore/MCP data, other
-containers, or volumes.
-
-## Real vs. synthetic vs. not-connected
-
-See `docs/demo-release/demo-concept.md` for the full breakdown. In short: auth/roles,
-vehicle/booking management, return preview/commit, the 5 data-quality rules and their
-resolutions, the audit trail, n8n orchestration, Docker deployment, and the automated
-test suite are all really implemented. The organisation, all people, vehicles, bookings,
-procedures, and the 5 named scenarios are synthetic. RAGcore and the ITWorx MCP Hub are
-not live-connected (honestly labelled "Demomodus"/"Niet gekoppeld" everywhere, never a
-fabricated success).
-
-## Test results
-
-### Backend (clean checkout, isolated stack)
-- `pytest`: **127 passed**
-- `ruff check .`: clean
-- `mypy app`: clean (48 source files)
-
-### Frontend (clean checkout, isolated stack)
-- `npm ci`: clean (pre-existing esbuild-moderate/react-router-RSC-high advisories,
-  unchanged from before this work — not introduced by it)
-- `tsc -b`: clean
-- `npm run build`: clean
-- Full Playwright suite: **56 passed** (against the isolated clean-checkout stack)
-
-### Guided-demo test
-`frontend/e2e/guided-demo-full.spec.ts` — one comprehensive test walking a fresh
-Operations Manager session through all 8 Demo Guide steps performing the real action at
-each step (processes the actual odometer-anomaly return, resolves the resulting
-data-quality issue, merges the duplicate customer, asks a suggested knowledge question,
-checks automation + audit, reviews the About page), then resets the demo data again to
-restore the environment. **Passed**, confirmed stable across repeated runs both locally
-and against the live Unraid deployment.
-
-### Clean-checkout drill
-Fresh `git clone` of this branch/commit into an isolated scratch directory, `.env` from
-`.env.example`, isolated Compose project name (`mobilityops-cleandrill`) and remapped
-host ports (`compose.override.yaml` with `!override` merge tags — no shared state with
-any other stack), `docker compose up --build -d` from empty volumes → migrations ran
-automatically (`e7b08389f47f (head)`) → seeded → full backend gate (127 passed, ruff/
-mypy clean) → `npm ci`/`tsc -b`/`vite build` clean → full Playwright suite (56 passed)
-→ reseeded and confirmed all 5 scenarios `ready: true` via the manifest → torn down
-(`docker compose down -v` on the isolated project only; the working dev stack was never
-touched).
-
-### Server deployment
-Deployed incrementally after every batch (10 deploy cycles across this work); final
-state: both `api` and `web` rebuilt and healthy at the final commit, `db` untouched
-across all of them (no destructive migrations on this branch). Migrations at
-`e7b08389f47f (head)` throughout. `.deploy/source-revision` on the server matches the
-final commit exactly.
-
-### Container health
-`docker compose ps` on the server: `api`, `db`, `web` all `healthy`, no restart loops.
-
-### Browser console / network
-No unexpected console errors on login, dashboard, scenarios, About, or with the Demo
-Guide open (verified via `demo-accessibility.spec.ts`; the one benign 401 from the app's
-own session-probe on first load is expected and explicitly accounted for, not silenced
-blindly). No unresolved server errors in `docker logs` for `api`/`web` at the time of
-this evidence capture.
-
-### Responsive / accessibility
-- Demo Guide renders as a correctly-anchored bottom sheet at 390px with no horizontal
-  overflow (`demo-accessibility.spec.ts`).
-- **Real bug found and fixed**: the Demo Guide's fixed desktop side panel overlapped
-  main content with no reflow, making the return form's "Review return" button
-  unclickable while the guide was open at ordinary desktop widths — this surfaced while
-  writing the full guided-demo test. Fixed via a `guide-open` layout class that reserves
-  space for the panel; regression-tested.
-- Demo badge and Demo Guide triggers are keyboard-focusable and operable (Enter to open,
-  explicit close controls).
-- Existing responsive-overflow checks (390/768/1280/1440px) remain green throughout.
-
-## Known limitations
-
-- RAGcore and the ITWorx MCP Hub are not live-connected in this environment (by design
-  — see scope). The knowledge assistant uses a local, English-only demo knowledge base;
-  a Dutch question against it returns "insufficient evidence" (verified empirically), so
-  suggested questions and the Demo Guide's step 6 instructions deliberately stay in
-  English rather than silently breaking the demo's centerpiece grounded-answer feature.
-- Existing operational screens (Dashboard, Vehicles, Bookings, Data Quality workbench,
-  Audit, Automation internals) remain in English; only new demo-productization surfaces

-# MobilityOps Unraid deployment evidence
-
-## Outcome
-
-- Deployment: **PASS**
-- Gitea publication: **PASS**
-- Gitea URL: `https://gitea.itworx.tech/Jens/MobilityOps`
-- Visibility: private (verified in the Gitea web UI)
-- Branch: `master`
-- Verified baseline commit: `4bf9afbeff44088864e0844769d4dd0e4089d85b`
-- Deployment implementation commit: `1e13943cffb2da8a328b5b1ea5e9b1fe73fdd774`
-- Server: `192.168.10.150`
-- Server directory: `/mnt/user/appdata/mobilityops`
-- Compose project: `mobilityops`
-- Application URL: `http://192.168.10.150:1236`
-- Port mapping: LAN `0.0.0.0:1236` / `[::]:1236` to `web:80`
-
-## Services and health
-
-| Service | Runtime state | Health | Host exposure |
-|---|---|---|---|
-| `db` | running, 0 restarts | healthy | none (`5432/tcp` internal) |
-| `api` | running, 0 restarts | healthy | none (`8000/tcp` internal) |
-| `web` | running, 0 restarts | healthy | `1236:80` on LAN |
-| shared host `n8n` | running | healthy | `5678:5678` on LAN; outside MobilityOps Compose |
-
-The final review topology reuses the n8n container that was already running on the host.
-Its empty public-host/editor URL settings were corrected in the persistent Unraid template
-so workflow execution URLs are valid. The temporary Compose-owned n8n container was
-removed without deleting its retained volume. Port `1236` was confirmed unused before the
-original deployment; the application directory was created specifically for MobilityOps.
-
-## Deployment commands
-
-The existing SSH aliases resolve to the requested hosts and keys (`gitea.itworx.tech`
-for Gitea SSH and `unraid` for root access). No key was created, copied, or replaced.
-The committed source was transferred from the workstation; Unraid has no Gitea key.
-
-Repository publication used the SSH clone URL supplied by Gitea:
-
-```bash
-git remote add origin ssh://git@192.168.10.150:222/Jens/MobilityOps.git
-git push -u origin master
-git push origin --tags
-```
-
-Git and the Gitea web UI both verified `master` as the default branch, the full commit
-history, baseline commit `4bf9afbeff44088864e0844769d4dd0e4089d85b`, and zero tags.
-The remote tree contains no `.env`, local database, `node_modules`, virtual environment,
-test cache, build cache, Playwright output, or browser binaries.
-
-```bash
-git archive --format=tar.gz --output=<temporary-archive> <commit>
-scp <temporary-archive> unraid:/mnt/user/appdata/mobilityops/.deploy/source.tar.gz
-ssh unraid
-cd /mnt/user/appdata/mobilityops
-tar -xzf .deploy/source.tar.gz
-./deploy/unraid/configure-env.sh http://192.168.10.150:1236
-docker compose -p mobilityops -f compose.yaml -f compose.unraid.yaml up --build -d db api web
-docker compose -p mobilityops -f compose.yaml -f compose.unraid.yaml exec -T api \
-  python -m app.cli seed --reset
-./deploy/unraid/setup-existing-n8n.sh \
-  n8n \
-  http://192.168.10.150:1236/api/v1/integrations/n8n/return-callback
-docker compose -p mobilityops -f compose.yaml -f compose.unraid.yaml up -d db api web
-```
-
-The server `.env` was created from `.env.example`, is mode `0600`, and contains generated
-runtime secrets. Secret values and n8n owner credentials remain server-only and are not
-included here or in Git.
-
-## Validation evidence
-
-- Migration: `e7b08389f47f (head)`.
-- Deterministic seed: users 2, customers 180, vehicles 50, bookings 246, inspections 75,
-  maintenance 40, data-quality issues 26, workflow runs 20.
-- HTTP: `GET /` returned 200; `GET /health` returned
-  `{"status":"ok","service":"mobilityops-api"}` through the web proxy.
-- Backend gates in an isolated local Compose project: 66 tests passed, Ruff clean, mypy
-  clean across 44 files.
-- Frontend: `npm ci && npm run build` completed (`tsc -b && vite build`).
-- Logs: no traceback, fatal, uncaught, or unresolved startup error in the deployment log
-  scan. Browser console had no warnings or errors during the smoke test.
-- Browser smoke test in Chrome: Operations Manager demo login, Dashboard, Vehicles,
-  Bookings, Data Quality, Knowledge, Automation, and Audit all loaded from the LAN URL.
-- Dashboard showed persisted seed metrics (21 available, 11 rented, 6 cleaning,
-  5 maintenance, 7 blocked, 22 open issues, 1 pending/failed workflow).
-- Return workflow: `BK-DEMO-RETURN` accepted 54,700 km, created `INSP-0076` and
-  `DQ-RET-0076`, preserved the 54,820 km canonical odometer, and changed the booking to
-  returned.
-- Shared-n8n round trip: final post-deploy event `98eb06dc-0bcc-4e3d-96ec-c23b2d266293`
-  reached `succeeded` on attempt 1 with no last error; the deterministic reset afterwards
-  restored `BK-DEMO-RETURN` to `active`.
-- Data quality: `DQ-RET-0076` displayed the persisted regression evidence and related
-  booking/inspection references.
-- Knowledge: UI truthfully showed `Provider: demo · available · 10 procedures indexed`;
-  the damage question returned grounded excerpts and citations from the local procedures.
-
-## Integration status
-
-- RAGcore: disabled for this deployment; `KNOWLEDGE_PROVIDER=demo`. No claim of a live
-  RAGcore connection is shown. Operational functionality is unaffected.
-- ITWorx MCP Hub: registration disabled with `MCP_HUB_REGISTRATION_ENABLED=false`; the
-  independently authenticated provider endpoints remain available internally to the web
-  proxy/API boundary, but no live Hub connection is claimed.
-- n8n: the existing server instance at `http://192.168.10.150:5678` is healthy; the
-  MobilityOps workflow is imported/published there and a real return delivery succeeded.
-  The bundled MobilityOps service is disabled by default in the Unraid overlay.
-
-## Known limitations
-
-- RAGcore and ITWorx MCP Hub are intentionally not connected yet.
-- Demo authentication remains the accepted HMAC-cookie PoC mechanism.
-- The dependency advisories already documented in final acceptance remain unchanged.
-
-## Redeploy
-
-From the workstation, create an archive of the desired committed revision and transfer it
-to `.deploy/source.tar.gz`. On Unraid, preserve `.env` and the named volumes, then run:
-
-```bash
-cd /mnt/user/appdata/mobilityops
-tar -xzf .deploy/source.tar.gz
-docker compose -p mobilityops -f compose.yaml -f compose.unraid.yaml up --build -d db api web
-docker compose -p mobilityops -f compose.yaml -f compose.unraid.yaml exec -T api alembic current
-curl -fsS http://127.0.0.1:1236/health
-```
-
-## Logs
-
-```bash
-cd /mnt/user/appdata/mobilityops
-docker compose -p mobilityops -f compose.yaml -f compose.unraid.yaml ps
-docker compose -p mobilityops -f compose.yaml -f compose.unraid.yaml logs --tail=200
-docker compose -p mobilityops -f compose.yaml -f compose.unraid.yaml logs -f api web
-docker logs -f n8n
-```
-
-## Safe rollback
-
-Choose a known-good commit on the workstation, archive and transfer it as above, then on
-Unraid extract it over the identifiable MobilityOps source directory and run the same
-`up --build -d` command. Preserve `.env` and both named volumes; do not use `down -v`,
-remove volumes, prune Docker, or modify unrelated containers. Check the target commit's
-Alembic compatibility before rolling application code behind the current database schema.

-# MobilityOps premium UI evidence summary
-
-Date: 2026-08-02
-Branch: `design/mobilityops-premium-ui`
-Baseline revision: `dfabb41582e302f45a3de826f85f531bf23dfc8b`
-Final design implementation commit: `1f292e14bb6a2e8ded5dc675b1b3360307d8a9ae`
-Review URL: `http://192.168.10.150:1236`
-
-## Outcome
-
-The working PoC was transformed into the Control Rail operational interface without
-changing backend contracts or adding scope. All existing journeys remain functional;
-return registration gained an evidence-based review boundary before commit.
-
-## Evidence index
-
-- Baseline audit: `docs/design/current-ux-audit.md`
-- Three directions and decision: `docs/design/design-directions.md`
-- Design tokens and component rules: `docs/design/design-system.md`
-- Stitch resource IDs: `docs/design/stitch-manifest.md`
-- Implemented visual validation: `docs/design/implementation-validation.md`
-- Baseline captures: `artifacts/design-validation/current/`
-- Stitch captures: `artifacts/design-validation/stitch/`
-- Final responsive captures: `artifacts/design-validation/implementation/`
-
-## Major implementation changes
-
-- Responsive Control Rail shell with compact top bar, desktop rail, off-canvas menu and
-  labelled mobile bottom navigation.
-- Live readiness band, filterable Attention queue, movement timeline, honest integration
-  pulse and persisted activity on the operations dashboard.
-- Searchable fleet and booking registries; booking client pagination limits the DOM to 25
-  operational rows; responsive tables retain field labels.
-- Capture → review → result return workflow with calculated consequence preview and no
-  write request before confirmation.
-- Match/conflict duplicate comparison, evidence-first knowledge, system-health cards and
-  expandable audit metadata.
-- Inline SVG product mark, Feather-like line icon set, CSS control-centre illustration,
-  timeline/status motion and reduced-motion fallback; no image or motion dependency.
-
-## Validation
-
-| Gate | Result |
-|---|---|
-| Backend tests | 66 passed |
-| Backend lint | ruff passed |
-| Backend types | mypy: 0 issues in 44 files |
-| Frontend types/build | passed; 59 modules; 240.24 kB JS and 36.63 kB CSS before gzip |
-| Browser journeys | 19 passed locally |
-| Horizontal overflow | none at 390/768/1280/1440 px |
-| Accessibility | named landmarks, skip link, visible focus, text-plus-shape status, labelled mobile rows, reduced-motion support |
-| Deployed browser smoke | passed on all 10 authenticated routes plus login at desktop and mobile sizes |
-| Console/network | 0 browser warnings/errors; 7 authenticated API paths returned HTTP 200 |
-| Deployed global search | Ctrl+K plus `MO-024` navigation passed against the review URL |
-
-All displayed operational counts remain derived from the existing persisted API data.
-Synthetic-data labelling is persistent on login and authenticated surfaces.
-
-Deployed evidence is stored in `artifacts/design-validation/implementation/deployed/`.
-The review stack reports healthy PostgreSQL/API state, HTTP 200 from the web application,
-and healthy state from the server's existing n8n at port 5678. A synthetic return reached
-`succeeded` on attempt 1 through that shared n8n and its MobilityOps callback; the demo was
-then reset to its deterministic state.
-
-## Performance observations
-
-No runtime font, image or animation dependency was added. The application uses inline SVG
-and CSS visuals, and the production bundle remains appropriate for this internal PoC.
-
-## Known limitations
-
-- Global search resolves Control Rail sections and `MO-*`, `BK-*`, `DQ-*` public
-  references. It intentionally does not offer customer lookup because the locked PoC has
-  no customer detail route or cross-entity search API.
-- The repository retains a bundled n8n service for standalone local clean-checkout demos.
-  The Unraid overlay keeps it behind the opt-in `bundled-n8n` profile; the live review
-  deployment uses the server's existing shared n8n instead.
-- The MCP Hub state is correctly shown as not configured in the current PoC rather than
-  simulated as healthy.
-- Live RAGcore and MCP Hub round trips remain subject to the existing environment limits
-  documented in `PROJECT_STATE.md`; their degradation behavior is unchanged.
-
-## Rollback
-
-The accepted baseline remains reachable at commit
-`dfabb41582e302f45a3de826f85f531bf23dfc8b`. To roll back the review deployment without
-rewriting git history, archive that revision, extract it over the application source on
-Unraid while preserving `.env` and Docker volumes, and run
-`docker compose -p mobilityops up -d --build`. Verify `/health` and port 1236 afterwards.

-# Fleet Ops — final acceptance evidence
-
-## Accepted implementation
-
-- Deployment source marker: current `master`; the application image was built from runtime commit `cb7edb0` and the following commits contain acceptance/evidence only.
-- Live demo: `http://192.168.10.150:1236` — public passwordless synthetic demo.
-- Deployment: Unraid `/mnt/user/appdata/mobilityops`, Compose project `mobilityops`.

-- Product name: Fleet Ops; MobilityOps remains the technical repository/deployment ID.
-
-## Clean acceptance — 2026-08-10
-
-```text
-Backend, isolated PostgreSQL: 241 passed, zero warnings
-Playwright, fresh local build: 152 passed (5.4 min)
-Playwright, live production:   152 passed (4.7 min)
-Ruff:                          clean

-Alembic:                       b913a72e8c14 (head)
-```
-
-The browser suite covers both roles, protected routes, booking/return/maintenance/user/privacy workflows, five data-quality resolution types, correlated audit, retryable orchestration, grounded knowledge in three languages, the complete guided demo, the recruiter highlights, keyboard behaviour and responsive layouts from 360 to 1440 px.
-
-The provider matrix explicitly covers both valid title contracts: the deterministic provider uses Markdown frontmatter titles, while production RAGcore returns curated localized presentation titles. Both must include the language-specific source fragment. The focused live matrix passed 3/3, followed by the complete 152/152 green production run.
-
-## Production hand-off state
-
-The final reset completed immediately before the verified Hub call at `2026-08-10T19:16Z` and restored:
-
-```text
-users 2 · customers 180 · vehicles 50 · bookings 254 · inspections 75
-maintenance 40 · data-quality issues 33 · workflow runs 20
-scenario_integrity.all_ready = true (5/5 scenarios)
-```
-
-API readiness is `ready`, PostgreSQL is `up`, and API, web, database, scheduled backup, Prometheus and Grafana are running healthy/current. No traceback or critical error appears in post-deployment API/backup logs.
-
-A pre-deployment custom-format backup was created and independently verified by SHA-256 plus `pg_restore --list`:
-
-`/mnt/user/appdata/mobilityops/backups/postgres/mobilityops-20260810T185833Z.dump`
-
-## External integration evidence
-
-- **Existing central n8n:** configured, dispatch enabled and operational. All four expected workflows have recent healthy heartbeats. The reset state contains 19 successful runs, zero pending, zero unexpected failures and one explicitly synthetic failed-retry scenario.
-- **RAGcore:** reachable and ready for tenant `northstar-mobility-demo`, workspace `mobilityops`, collection `internal-procedures`. Exact identity lookups independently confirm 11/11 active published documents in each of NL/EN/FR; the latest n8n report separately records 33 synchronized documents and zero failures. The canonical parsed-artifact hash is not misrepresented as a raw-source hash.
-- **ITWorx MCP Hub:** registration is enabled, the Hub is reachable and Fleet Ops is **operational**. Three real `mobilityops.operations.summary` verification calls are audited under the Hub's tenant-bound client identity; the final short-lived bearer produced HTTP 200/JSON and HTTP 401 after immediate revocation. All exposed Fleet Ops tools remain read-only.
-
-## Recruiter and visual acceptance
-
-The public entry now offers a direct **90-second Highlights** route. It links three product actions to their engineering proof, while the **Engineering** workspace explains domain ownership, commit-before-orchestration, citation-bound AI, security and explicit scope.
-
-Interactive live inspection confirmed:
-
-- no horizontal overflow on Highlights or Engineering at desktop; automated coverage confirms 360/390 px mobile layouts;
-- clear hierarchy, consistent primary actions and readable proof cards;
-- compact remaining-attention action (count badge, two-line label, small directional icon) without the former stretched empty panel;
-- truthful live n8n/RAGcore/MCP labels after reset, including 11 verified RAG documents and the real Hub client/tool evidence;
-- no dead links, placeholder numbers or unexplained raw data-quality references;
-- complete synthetic-data disclosure on login and in the persistent shell.
-
-Current evidence images are in `artifacts/evidence/screenshots/`:
-
-- `1-login.png`
-- `2-highlights.png`
-- `3-engineering-story.png`
-- `4-dashboard.png`
-- `5-knowledge-evidence.png`
-- `6-highlights-mobile.png`
-
-## Deliberate boundary
-
-This is a completed, production-shaped public demo—not claimed customer adoption and not a general ERP. Accounting, payments, public reservations, CRM, inventory, HR, a second RAG stack, a separate MCP server and autonomous write agents remain intentionally excluded. A real personal-data rollout would additionally require the adopting organisation's identity provider, retention approvals, secrets lifecycle, alert ownership and disaster-recovery governance.

-# Fleet Ops final integrations — evidence summary
-
-Session date: 2026-08-05. Branch `feat/fleet-ops-final-integrations`.
-
-## Repository state
-
-| Repo | Start | End | Branch | Notes |
-|---|---|---|---|---|
-| Fleet Ops (MobilityOps) | `3ebca9e` (from `feat/live-n8n-ragcore-integration`) | `727c19a` (+ e2e test fixes, uncommitted at write time) | `feat/fleet-ops-final-integrations`, pushed to `origin` | 3 commits: `34df66d`, `2ae2044`, `727c19a` |
-| RAGcore | `64a908a` | `64a908a` (+1 isolated commit `ce0ad56`) | `main` | Only a backlog handoff entry committed; no code changes (36-file concurrent-session collision — see below) |
-| ITWorx MCP Hub | not modified this session | — | `feature/wp240-final-acceptance` | Connector already live in production before this session started; not touched |
-
-## Deployed revisions
-
-- Fleet Ops: `http://192.168.10.150:1236`, redeployed twice this session (after Batches
-  1-3 and after Batch 4), `docker compose -p mobilityops -f compose.yaml -f
-  compose.unraid.yaml up --build -d db api web`, `.deploy/source-revision` = `727c19a...`.
-- RAGcore: `http://192.168.10.150:1237`, `ragcore-app-1`. No image redeploy — the two live
-  fixes (filesystem permissions, reranker model pull) were applied directly to the
-  running container/Ollama instance, not via a code deploy.
-- ITWorx MCP Hub: `http://192.168.10.150:1100` (Tower), unchanged, already live before
-  this session at commit `c4a0f6d` per the Hub's own state.
-
-## GUI polish (Batch 1)
-
-- Dashboard Attention Queue: curated severity mix (grouped "Handle now / Follow up
-  today / Review later"), replacing pure severity-sort that let `high` crowd out
-  everything else.
-- Today's Movements: seed data curated (`seed/bookings.csv`) so a fresh reset shows ≥2
-  departures and ≥2 returns; new `test_seed_today_movements_are_a_credible_mix` test.
-  Live-verified after a real demo reset: 2 returns + 2 departures shown.
-- About Demo: restructured into a compact grid with `<details>` progressive disclosure
-  for architecture/security/testing sections.
-- Duplicate Customer Merge: match/conflict counts shown, matching fields hidden by
-  default (toggle to reveal), compact preview of the merged record before confirmation.
-- Repo hygiene: removed a stray empty `backend;C` dir and an untracked 31MB zip export;
-  `.gitignore` now excludes future archive exports.
-- All four live-verified via browser against the deployed instance (see screenshots
-  taken during the session — not separately saved to disk).
-
-## n8n (Batch 2)
-
-- 4 canonical workflows confirmed live: Vehicle Return Orchestration, Scheduled Data
-  Quality Scan, RAGcore Procedure Sync, Workflow Error Handler.
-- Fixed genuinely invalid JSON in the committed `fleet-ops-vehicle-return.json` (a
-  missing `},` between two node objects — the file could not be parsed).
-- Workflow 3 (RAGcore Procedure Sync): confirmed 6 real nodes built and saved. Found and
-  fixed two real defects via the safe `n8n import:workflow` CLI path (not the REST API,
-  which caused a documented wipe incident in an earlier session): three body-parameter
-  expressions had a stray trailing `}}`, and `settings.errorWorkflow` was unset. Exported
-  the corrected definition to `n8n/workflows/fleet-ops-ragcore-procedure-sync.json`,
-  added to `MANIFEST.md` and `check_drift.py`.
-- **Not published** — the Schedule Trigger runs daily at midnight; activating it starts
-  real unattended production runs, deliberately left as a separate go-live decision.
-- No no-op/sync/error-handler live-execution smoke test was run this session beyond the
-  structural CLI-export verification above (workflow remains unpublished).
-
-## RAGcore (Batch 3)
-
-- **Root cause found and fixed, live, user-approved**: the "zero retrieval candidates"
-  bug was a filesystem permission bug (`/workspace/.state/models/embedding_profiles.json`
-  was `root:root` mode `600` on the host bind mount, unreadable by the app's actual
-  runtime uid 10001) — not authorization, not Qdrant, not embeddings, all independently
-  verified healthy first. Fixed via `chown`/`chmod`; re-verified in-process (5 real hits,
-  up from 0).
-- **Second, deeper gap found, not fixed**: the reranker adapter calls
-  `{ollama}/api/rerank`, a route this Ollama version (`0.32.5`) does not serve (404).
-  Pulled a working model (`xitao/bge-reranker-v2-m3:latest`, 1.2GB, approved) — did not
-  fix it, since the problem is the HTTP route, not the model. `/v1/answers` still returns
-  `not_answerable`/0 citations for real questions against real matching content.
-- User decision: leave `KNOWLEDGE_PROVIDER=demo`; hand the reranker fix off to RAGcore's
-  own backlog (`docs/ai/BACKLOG.yaml`, task `M8-01`, committed in that repo as `ce0ad56`
-  — the only commit made in RAGcore this session) rather than editing RAGcore code amid
-  its own 36-file concurrent-session collision.
-- Side effect: minting the live-verification credential rotated the existing "Fleet Ops
-  Knowledge Assistant (production)" service account's credential (2-active-credential cap
-  reached). A fresh credential must be issued before actually flipping the provider live.
-
-## MCP Hub (Batch 4)
-
-- Confirmed the Fleet Ops connector is already live in production on the Hub side
-  (Tower, commit `c4a0f6d`), with a real contract fix already applied there
-  (`vehicle.get`'s wire parameter normalized to camelCase `vehicleRef`).
-- Fixed two concrete gaps in Fleet Ops's own `search-knowledge` endpoint: no `locale`
-  field existed at all (now `nl-BE`/`en-GB`/`fr-BE`, wired to the knowledge provider's
-  existing `language` param), and the correlation ID was always freshly minted, ignoring
-  any inbound `X-Correlation-Id` header. Added `get_correlation_id`, applied to all four
-  MCP endpoints.
-- `MCP_HUB_BASE_URL` was dead config (declared, never read); wired it for a real,
-  bounded Hub-reachability health check instead of an unneeded self-registration push
-  (the Hub's own registration is catalog-driven).
-- Renamed Fleet Ops's own internal audit tool labels `mobilityops_*` → `fleet_ops_*`
-  (mirrored in `contracts/mcp-tools.json`, `mobilityops_*` kept as deprecated aliases).
-  The live Hub connector's own dotted tool namespace (`mobilityops.operations.summary`
-  etc.) is a separate, Hub-owned naming layer, deliberately not touched.
-- Automation page's MCP card now shows real evidence (last tool/client/count/timestamp)
-  instead of only the registration-enabled boolean.
-
-## AI Operations Brief (Batch 5)
-
-Real MCP-client-shaped run via the live ITWorx MCP Hub connector's own
-`MobilityOpsClient` class against production Fleet Ops. Full runbook and live output in
-`docs/final-integrations/ai-operations-brief-runbook.md`. Summary:
-
-- Real operations summary (21 available / 11 rented / 6 cleaning / 5 maintenance /
-  7 blocked; 23 open quality issues).
-- Real most-pressing vehicle identified (`MO-031`, missing operational inspection).
-- Real vehicle detail lookup.
-- Real grounded knowledge answer (English damage-handling question): 2 real citations,
-  `evidence_state: grounded`.
-- Dutch/French variants of the same question honestly returned `insufficient` (no
-  fabrication) — root cause: the live Hub connector doesn't yet send the new `locale`
-  field, a Hub-side follow-up, not silently worked around.
-- Correlation IDs verified end-to-end in Fleet Ops's own audit log
-  (`GET /api/v1/audit?action=mcp_tool_request`), matching the response payloads exactly.
-- No write actions performed at any point.
-
-## Testing per batch
-
-- Backend: **176 passed**, `ruff check .` clean, `mypy app` clean (50 source files) —
-  verified against a freshly rebuilt image after discovering mid-session that
-  `docker compose run --rm api` (no bind mount on the `api` service) silently tests a
-  stale image otherwise. One genuinely stale test assertion found and fixed as a result.
-- Frontend: `tsc -b && vite build` clean.
-- E2e (Playwright, against the live deployed instance,
-  `MOBILITYOPS_PUBLIC_URL=http://192.168.10.150:1236`): every spec file run this
-  session passed — `demo.spec.ts`, `interactive-elements.spec.ts` (26),
-  `responsive-i18n.spec.ts` + `demo-accessibility.spec.ts` + `guided-demo-full.spec.ts`
-  (28), `i18n-coverage.spec.ts` + `error-messages.spec.ts` + `clickable-rows.spec.ts` +
-  `demo-guide.spec.ts` + `demo-entry.spec.ts` + `demo-legibility.spec.ts` +
-  `fleet-ops-correction.spec.ts` + `ui-redesign.spec.ts` + `greeting.spec.ts` +
-  `greeting-live.spec.ts` (28, after fixing 2 pre-existing fragile locators unrelated to
-  this session's feature work — a `.data-table` ambiguity now that Automation has two
-  tables, and a `Technische details` toggle ambiguity for the same reason; plus one
-  pre-existing untranslated-loanword false positive in `i18n-coverage.spec.ts`).
-
-## Known limitations, stated plainly
-
-- `KNOWLEDGE_PROVIDER` is still `demo`, not `ragcore` — blocked on RAGcore's own
-  reranker gap (handed off, not fixed this session).
-- n8n workflow 3 is built and correct but not published (deliberate, separate decision).
-- The live MCP Hub connector doesn't yet send the new `locale` field, so
-  locale-aware knowledge search only works when called directly against Fleet Ops (as
-  proven by the backend tests), not yet through the live Hub connector as deployed.
-- No public-demo-readiness checklist, About Demo Guide "completed" end-state polish
-  (section 4E), or dashboard MCP "activity showcase after Demo Complete" gating were
-  built this session — the MCP evidence display exists on the Automation page
-  unconditionally rather than gated behind guided-demo completion.
-- No security-review pass was run separately this session (existing gates: ruff, mypy,
-  the repo's own auth/audit test coverage).
-
-## Rollback
-
-- Fleet Ops: prior working revision `0571a40` remains in `.deploy/` as
-  `source-0571a40.tar.gz` on the Unraid host; redeploy by re-extracting and re-running
-  the same `docker compose up --build -d` sequence with that archive.
-- RAGcore: `chown`/`chmod` change is trivially reversible (`chown 0:0` +
-  `chmod 600` on the same path) if needed, though there is no reason to revert a
-  permission fix. Ollama model pull (`xitao/bge-reranker-v2-m3:latest`) can be removed
-  with `ollama rm` if unwanted; it is inert until RAGcore's own code is changed to use it.
-- MCP Hub: not modified this session.

-
-## What this correction fixed
-
-1. **Status-recommendation flow redesigned** (sections 8A–8F). The old single opaque
-   "calculate and apply recommended status" action is replaced by a single shared, pure
-   evaluator (`backend/app/services/vehicle_status.py::evaluate_vehicle_status`,
-   documented in `docs/fleet-ops-correction/vehicle-status-decision-table.md`) used
-   identically by the scanner, a non-mutating preview endpoint
-   (`POST /api/v1/data-quality/issues/{ref}/status-recommendation`), and a
-   transactional apply endpoint (`POST .../apply-recommended-status`) that locks the
-   row, recomputes facts, rejects a stale `recommendation_token`, refuses unsafe/manual-
-   review recommendations, and re-validates post-write before resolving the issue.
-   - Forbidden shortcuts eliminated: "maintenance + active booking" no longer
-     auto-recommends "rented" (being in maintenance is itself now a blocking fact);
-     "maintenance with nothing else wrong" no longer auto-clears to "available" (no
-     fact proves maintenance is actually finished — release stays a manual decision).
-   - Frontend: "Review recommendation" → a localized decision panel (current/
-     recommended status, why, evidence, consequences) → an exact "Change status to
-     <status>" confirm action → result, or a distinct "Manual review required"
-     state offering no generic apply button.
-2. **MO-016 order independence** (section 9). Order independence does not mean "same
-   final status regardless of order" — resolving the booking overlap first genuinely
-   removes the conflict, correctly leaving nothing to apply. What holds either way: the
-   recommendation always reflects real current facts (never a stale proxy), and nothing
-   unsafe is ever applied (never "rented"). Proven by a backend test explicitly scoped
-   to MO-016/DQ-DEMO-STATUS (the original version wasn't — `_first_open()` returned
-   whichever of ~14 open `vehicle_status_conflict` issues was most recent, not
-   necessarily MO-016's) and a browser-level Playwright test covering both orders.
-3. **"Fleet Ops" is a non-localizable brand constant** (`frontend/src/product.ts`,
-   backend `PRODUCT_NAME`), wired via `{{productName}}` interpolation everywhere the
-   brand appeared in locale prose. A permanent test fails the build if any locale file
-   ever defines the brand name or an `appName` key again.
-4. **Dynamic backend prose converted to message codes + params** (sections 5/6/10):
-   return status reasons, audit field/actor-type labels, automation `last_error` (new
-   `last_error_code` column, migration `799d8800e241`), search results (sections/
-   vehicles/bookings/issues), and — found live on Unraid — the data-quality evidence
-   summary. Raw technical text is demoted to a "Technical details" disclosure
-   everywhere.
-5. **Knowledge-base fixes**: the demo provider's tokenizer silently dropped accented
-   characters (`[a-z0-9]+` split "véhicule" into "v"+"hicule"), breaking French
-   retrieval broadly — fixed to include the Latin-1 accented range. Reweighted section
-   scoring so a body match (real substance) outranks a heading/title match (a shallow
-   structural hint) — the old weighting misranked the damage procedure behind an
-   unrelated document for the brief's exact validation question in all 3 languages.
-   Removed leftover "MobilityOps"/"PoC" mentions from 9 procedure documents.
-6. **Search, audit, automation, maintenance/inspections localized** (section 10):
-   backend returns stable codes + params only; the frontend localizes section labels,
-   vehicle summaries, booking/issue statuses, audit action/field/actor labels,
-   automation error explanations, and maintenance/inspection type labels.
-7. **i18n test suite strengthened** (section 11): key parity, brand invariant,
-   translation-quality (cross-locale identical-value detection), a hardcoded-JSX-text
-   static scan (had to anchor on backreferenced closing-tag names — a naive `>text<`
-   regex misread TypeScript generics as JSX), and a 3-language route matrix (every main
-   route, no console errors, correct `html[lang]`, real page headings).
-
-## Live-caught bug (the deployment validation earning its keep)
-
-Live validation on the freshly-deployed fix branch directly caught a real defect: every
-data-quality issue's top-of-page evidence summary was unconditionally showing raw,
-always-English text (e.g. *"vehicle marked available while reserved bookings
-conflict"*) in **all three languages**, because the frontend never finished the
-`evidence.signals` localization the backend had already been emitting (the backend code
-even had a comment describing the intended design that the frontend didn't implement).
-Fixed in commit `2e4fb43`:
-- `DataQualityIssueDetail.tsx` now renders `evidence.signals` through the operator's
-  locale as the primary evidence text.
-- The four `DQ-DEMO-*` seed rows that anchor the guided demo's scripted scenarios now
-  carry real, accurate signals computed at seed time (the duplicate-customer similarity
-  score is the actual `SequenceMatcher` ratio on the seeded names, not invented).
-- Rows with no structured signals fall back to raw text rather than showing a blank
-  summary; the one known filler placeholder gets its own localized rendering.
-- A regression test locks this in: the vehicle-status-conflict evidence summary must
-  show localized text and must never contain the specific raw English sentence that was
-  live-visible before the fix, in all 3 languages.
-
-Also found and fixed along the way: a frontend logic bug conflating "no conflict" with
-"manual review required" (both carry `safe_to_apply: false`), which showed a false
-"manual review required" panel for MO-016 after its booking overlap was resolved
-instead of the correct "no change needed" state (fixed in `1fdd2b3`).
-
-## Translation coverage
-
-- All three locale files (`nl-BE`, `en-GB`, `fr-BE`) define exactly the same key set
-  for every namespace (`i18n-coverage.spec.ts`, structural guarantee).
-- No locale file contains an empty string value.
-- No locale file defines the brand name or an `appName` key (brand-invariant test).
-- Cross-locale translation-quality check: for every string ≥8 characters of real prose,
-  nl-BE ≠ en-GB, fr-BE ≠ en-GB, fr-BE ≠ nl-BE, with a precise, audited allowlist for
-  genuine proper nouns/cognates (23 entries, each with a documented reason).
-- Hardcoded-JSX-text static scan: zero findings against the current codebase (verified
-  against both false positives — TypeScript generics — and a deliberately-injected-
-  then-reverted false negative).
-- 3-language route matrix: every main route (dashboard, vehicles, vehicle detail,
-  bookings, booking detail, data quality, issue detail, automation, knowledge, audit,
-  scenarios, about) opens cleanly in all 3 languages with no console errors, correct
-  `html[lang]`, and a real page heading.
-- **Remaining visible wrong-language text**: none found. The one gap that existed (the
-  data-quality evidence summary) was found live and fixed before merge.
-
-## Branding
-
-- Visible product name: **Fleet Ops**, exactly, in all 3 languages, everywhere (login,
-  topbar, footer "Fleet Ops Demo", document title, About page, Demo Guide, knowledge
-  base). Verified structurally (brand-invariant test) and live (branding test across
-  dashboard/vehicles/data-quality/audit/automation/knowledge pages in all 3 languages;
-  visual screenshots of the login screen in nl-BE and fr-BE).
-- Technical identifier retained (by design, per the brief): repository name, local
-  directory, package/module names, Compose project, deployment directory, database
-  name, and the `/health` endpoint's `service: "mobilityops-api"` field remain
-  "mobilityops" — none of these are visible UI text.
-- No visible "MobilityOps" or "PoC" anywhere in the UI or the demo knowledge base
-  (9 procedure documents cleaned up; regression test in `test_knowledge.py` scans every
-  procedure file for both strings).
-
-## Status-preview / apply / manual-review / MO-016 ordering
-
-- **Preview**: verified non-mutating — the issue's `status` stays `"open"` after
-  calling the preview endpoint and re-fetching it via a fresh request.
-- **Apply**: the confirm button names the exact target status ("Change status to
-  Blocked" / "Status wijzigen naar Geblokkeerd" / "Changer le statut vers Bloqué");
-  applying resolves the issue and updates the vehicle atomically.
-- **Manual review**: MO-024 (active rental + service-threshold reached, a genuine fact
-  contradiction) shows "Manual review required" with no generic apply button rendered
-  at all.
-- **Stale token**: simulated by resolving the underlying booking overlap after the
-  preview was fetched but before applying — the apply call is correctly rejected
-  (`RECOMMENDATION_STALE`), the UI shows the "situation has changed" message, and the
-  user must review again before a new apply is possible.
-- **MO-016 ordering**: both orders tested. Resolving the overlap first correctly leaves
-  nothing to apply (vehicle stays "available", genuinely correct). Resolving the status
-  conflict first safely blocks the vehicle; resolving the now-redundant overlap
-  afterwards does not disturb it. Neither order ever produces "rented".
-
-## Knowledge (per language)
-
-The brief's exact validation question, in each language, grounds on the damage
-procedure as the **primary** (not just top-3) source:
-- nl-BE: *"Wat moet ik doen wanneer een voertuig beschadigd terugkomt?"* → damage
-  procedure, Dutch source, Dutch excerpt.
-- en-GB: *"What should I do when a vehicle returns with damage?"* → damage procedure,
-  English source, English excerpt.
-- fr-BE: *"Que dois-je faire lorsqu'un véhicule revient endommagé ?"* → damage
-  procedure, French source, French excerpt.
-
-This required two real fixes: a tokenizer bug that silently dropped accented
-characters (breaking French retrieval broadly) and a scoring-weight rebalance (body
-matches now outrank heading/title matches).
-
-## Audit / automation
-
-- Audit: action labels localized (`workflow_retry` → "automatisering opnieuw
-  geprobeerd" / "automation retried" / "automatisation relancée", etc.), field names
-  localized (`operational_status` → "Operationele status" / "Operational status" /
-  "Statut opérationnel"), actor types localized, raw technical codes only inside
-  "Technical details". Verified live and via a dedicated Playwright test.
-- Automation: the seeded synthetic failure shows a localized primary explanation
-  ("De workflowdienst was tijdelijk niet bereikbaar…") with the raw technical message
-  ("Synthetic connection timeout to n8n") only under "Technical details". Verified live
-  and via a dedicated Playwright test.
-
-## Backend tests / lint / types
-
-- `pytest`: **151 passed**, 0 failed (clean checkout, local dev, and post-merge master
-  — run four times across this correction, always 151/151).
-- `ruff check .`: all checks passed, every run.
-- `mypy app` (strict): no issues found in 49 source files, every run.
-- Alembic: `alembic upgrade head` from empty database lands on `799d8800e241`
-  (the new `outbox_events.last_error_code` column); `downgrade -1` / `upgrade head`
-  round-trip verified.
-
-## Frontend build / Playwright
-
-- `npm ci`, `tsc -b`, `vite build`: clean, every run.
-- Full Playwright suite: **116 tests**, run repeatedly against the local dev stack, an
-  isolated clean-checkout stack, the live fix-branch deployment, and the live
-  post-merge master deployment — **116/116 passed** on the final master-deployment run
-  and on the final local run. A handful of transient, sequential-run-only flakes
-  occurred at various points across ~10 full-suite runs today (different test each
-  time, e.g. a pre-existing logout-timing race in `AuthContext.logout()` unrelated to
-  this branch); every single one was confirmed to pass cleanly in isolation.
-- Guided demo covered indirectly via `guided-demo-full.spec.ts`,
-  `demo-guide.spec.ts`, and the route matrix across all 3 languages — no dedicated
-  "run the guided tour end-to-end in French" script exists beyond what those specs plus
-  the branding/route-matrix tests already exercise, since the guided tour's steps route
-  through the same pages already covered per-language.
-
-## Clean-checkout drill
-
-Fresh `git clone --branch fix/fleet-ops-i18n-status-flow` of only committed files into
-an isolated Compose project (`cleancheckfleetops`, ports 8129/1229/5679 to avoid
-colliding with the working dev stack). From empty volumes: build → up → `alembic
-upgrade head` → `reset_and_seed` (50 vehicles / 180 customers / 246 bookings / 27
-data-quality issues / 20 workflow runs) → 151 backend tests + Ruff + mypy green →
-frontend build green → full Playwright suite green → final reset →
-`scenario_integrity.all_ready: true`. Isolated stack, containers, volumes, and images
-torn down afterward; working dev environment confirmed untouched.
-
-## Unraid deployment
-
-Deployed via `git archive` → `scp` → extract into `/mnt/user/appdata/mobilityops`
-(preserving `.env` and persistent volumes) → `.deploy/source-revision` → rebuild
-`api`+`web` → `alembic upgrade head` → reset/reseed. Done twice: once for the fix
-branch (caught the evidence-summary bug), once for the final merged master. Both times:
-containers healthy, no errors in `api`/`web` container logs, full Playwright suite
-green against the live server, `scenario_integrity.all_ready: true` after final reset.
-RAGcore and MCP Hub were not activated (the demo `KnowledgeProvider` — deterministic
-local retrieval — remains what's live, per the brief's constraint against activating
-unvalidated live integrations).
-
-## Responsive / accessibility
-
-- Breakpoint matrix (1440×1000, 1280×800, 1024×768, 768×1024, 430×932, 390×844,
-  360×800) × 3 languages: no horizontal overflow, localized headings visible
-  (`responsive-i18n.spec.ts`).
-- Status-recommendation panel: keyboard-only activation of "Review recommendation" and
-  "Change status to X" verified via focus assertions (not just click); reduced-motion
-  emulated during the flow; status never conveyed by colour alone (the badge always
-  carries its own localized text); `aria-live="polite"` added so the applied
-  confirmation is announced to screen readers.
-
-## Known limitations
-
-- A pre-existing, narrow timing race in `AuthContext.logout()` (clears local state and
-  redirects before awaiting the server-side cookie-clearing POST) occasionally flakes
-  one specific Playwright test only under heavy sequential load; not introduced by this
-  branch, not fixed (out of this branch's scope), always passes in isolation.
-- The 11 generic `DQ-0xxx` filler seed rows (not tied to a named demo scenario) show a
-  localized generic placeholder rather than rich structured evidence, since they carry
-  no real underlying data gap to describe accurately (the CSV's placeholder text
-  doesn't correspond to an actually-missing field on the referenced vehicles).
-- No dedicated "full guided demo in French, screenshot every step" script exists as a
-  single artifact; coverage is composed from the route matrix, branding, and existing
-  guided-demo specs, each run across all 3 languages.
-
-## Screenshots
-
-`artifacts/fleet-ops-correction/screenshots/`, all captured live against
-`http://192.168.10.150:1236`:
-
-- `login-nl-BE.jpg` — login screen, Dutch (default), "Fleet Ops" brand + "Bedieningscentrum" subtitle.
-- `login-fr-BE.jpg` — login screen switched to French, "Fleet Ops" brand + "Centre de contrôle" subtitle, "Organisation de démo : Northstar Mobility (fictive)".
-- `dq-demo-status-fr-BE-collapsed.jpg` — DQ-DEMO-STATUS in French: the localized evidence summary ("Ce véhicule a deux réservations qui se chevauchent…") replacing the raw English sentence, in its collapsed pre-review state.
-- `dq-demo-status-fr-BE-clean-reload.jpg` — the same page after a clean reload, confirming the fix is stable across navigation.
-
-One capture attempt mid-session showed the brand rendered as "Vlootoperaties" instead
-of "Fleet Ops" — investigated immediately via `document.documentElement` inspection and
-confirmed to be **Chrome's own built-in page-translate feature** auto-triggering on the
-automation browser profile (`class="translated-ltr"`, `lang` rewritten to bare `"nl"`
-by Google Translate, not the app), re-triggering specifically on React DOM mutations
-from clicking through the panel. Not an application defect: a clean reload immediately
-after showed the correct "Fleet Ops" brand and correctly localized French content
-again, and none of the 116 Playwright tests (which run in a clean automated browser
-context without this extension behaviour) ever observed it.
-
-## Rollback procedure
-
-1. `ssh unraid`, `cd /mnt/user/appdata/mobilityops`.
-2. `git archive --format=tar 18344bc -o` (from a local clone) → `scp` → extract, or
-   restore from the previous `.deploy/source-revision` (`18344bc8b7a75a2f868bf15bf498fc030ac6c34c`).
-3. `echo 18344bc8b7a75a2f868bf15bf498fc030ac6c34c > .deploy/source-revision`.
-4. `docker compose -f compose.yaml -f compose.unraid.yaml build api web && ... up -d api web`.
-5. `alembic downgrade e7b08389f47f` if the `last_error_code` column must also be
-   rolled back (not required for a same-schema rollback within this correction's own
-   history, only if reverting past the whole correction).
-6. Re-seed and re-verify `scenario_integrity.all_ready: true`.
-
-The fix branch `fix/fleet-ops-i18n-status-flow` was not deleted.

-# Fleet Ops final localization — final summary
-
-Small, targeted correction round on top of the already-merged, functionally-validated
-Fleet Ops correction milestone. Scope: remaining NL/FR translation gaps, centralized
-API-error localization, a time-dependent Europe/Brussels dashboard greeting, i18n
-test hardening, and documentation consistency — explicitly no redesign, no business-logic
-changes, no new functionality. Audit and rationale: `docs/fleet-ops-final-localization/audit.md`.

-
-## Product name and supported languages
-
-- Visible product name: **Fleet Ops**, everywhere, never translated (`frontend/src/product.ts`
-  constant, interpolated as `{{productName}}`). "MobilityOps" remains the internal repo /
-  Compose project / deployment-directory identifier only.
-- Supported UI languages: **nl-BE** (default), **en-GB**, **fr-BE**.
-- No visible "MobilityOps" or the word "PoC" anywhere in the UI (enforced by a dedicated
-  automated test, see below).
-
-## Corrected translations
-
-- Role names actually translated (not just labelled as translated): `auth.json` /
-  `demo.json` role keys — **Operationsmanager** / **Verhuurmedewerker** (nl-BE),
-  **Responsable des opérations** / **Collaborateur de location** (fr-BE).
-- `audit.title` → **Auditgeschiedenis** / **Piste d'audit**; `columns.actor` → **Uitvoerder**
-  (nl-BE) / **Auteur** (fr-BE, corrected during live browser validation — see Known
-  limitations).
-- `list.statusOpen` → **Openstaand**; `ledger.filterRecent` → **Recentste**;
-  `scenarios.startScenario` → **Scenario starten** / **Démarrer le scénario**.
-- 8 previously-missed mid-sentence "Audit trail" leaks fixed across `demo.json`,
-  `quality.json`, `returns.json` (nl-BE) — found by the new embedded-substring test, not
-  the pre-existing whole-string-identity test, which structurally cannot catch this class
-  of bug.
-- No unintended English text remains in nl-BE or fr-BE (see translation-coverage evidence
-  below).
-
-## Removed allowlist exceptions
-
-Removed 7 now-stale `IDENTICAL_VALUE_ALLOWLIST` entries in `i18n-coverage.spec.ts`:
-`audit.title`, `auth.roleOperationsManager`, `auth.roleRentalEmployee`,
-`demo.scenarios.startScenario`, `demo.scenarios.roles.operations_manager`,
-`demo.scenarios.roles.rental_employee`, `navigation.items.audit` — all now genuinely
-translated; their old comments describing them as "deliberately untranslated" were no
-longer true. Two new tests added: embedded-English/Dutch-substring leak guard, and a
-no-"MobilityOps"/no-"PoC" guard.
-
-## Hardcoded-text result
-
-The pre-existing static JSX scanner (`i18n-coverage.spec.ts`, section 11D) found **zero**
-hardcoded user-facing strings outside the approved technical-token allowlist (Fleet Ops,
-Northstar Mobility, ITWorx MCP Hub) across `pages/` and `components/`. Result: **PASS**.
-
-## API-error-localization result
-
-New `frontend/src/api/errorMessages.ts` (`describeApiError`) replaces the
-`err instanceof ApiError ? err.message : t(fallback)` anti-pattern (which showed raw
-English backend text for the common case) at all 13 call sites across 7 files
-(`Automation.tsx`, `ReturnForm.tsx`, `DataQuality.tsx`, `DemoGuide.tsx`, `Layout.tsx`,
-`DataQualityIssueDetail.tsx` ×7 sites, `Knowledge.tsx`). Resolution order: known `AppError`
-code (32 codes) → known HTTP status (401/403/404/409/422/500) → fully generic fallback.
-New `ApiErrorNotice` component (`PageChrome.tsx`) always renders a localized title +
-explanation + optional next step; raw backend text is demoted to a "Technical
-details"/"Détails techniques" disclosure, never the primary message.
-
-Evidence: `frontend/e2e/error-messages.spec.ts` (10 tests, all passing) —
-every known code/status has non-empty copy in all 3 locales; a known code never surfaces
-raw text as the primary message; unknown-code and unknown-status fallback chains behave
-correctly; a drift guard greps the actual backend `AppError("CODE", ...)` call sites and
-confirms `KNOWN_CODES` exactly matches (32 codes, zero drift). Live-verified on Unraid: the
-seeded failed automation run renders a fully localized French error with a "DÉTAILS
-TECHNIQUES" disclosure below it.
-
-## Greeting logic and edge cases
-
-New `frontend/src/i18n/greeting.ts` (`getGreetingPeriod`, clock-injectable, pure) resolves
-one of 4 periods against **Europe/Brussels** wall-clock time via
-`Intl.DateTimeFormat({ timeZone: "Europe/Brussels", hourCycle: "h23" })` (DST-safe by
-construction — no manual UTC-offset math):
-
-| Period | Window | nl-BE | en-GB | fr-BE |
-|---|---|---|---|---|
-| morning | 05:00–11:59 | Goedemorgen | Good morning | Bonjour |
-| afternoon | 12:00–17:59 | Goedemiddag | Good afternoon | Bonjour |
-| evening | 18:00–22:59 | Goedenavond | Good evening | Bonsoir |
-| night | 23:00–04:59 | Welkom terug | Welcome back | Bon retour |
-
-Never "Goedenacht" (a farewell in Dutch, not a welcome). Each period also has its own
-accompanying sentence per language (`dashboard.json` `greetingBody`), replacing the old
-fixed "Here's the fleet." `useGreetingPeriod.ts` polls every 30s so the greeting rolls
-over live while the app stays open, no reload required; initial render uses a synchronous
-`useState(() => getGreetingPeriod())` so there is never a flash of the wrong period.
-
-Edge-case evidence:
-- `frontend/e2e/greeting.spec.ts` (4 tests): exact boundary checks at 04:59/05:00/11:59/
-  12:00/17:59/18:00/22:59/23:00 in both CET (winter) and CEST (summer), plus a dedicated
-  spring-forward/fall-back DST-transition test (2026-03-29 and 2026-10-25).
-- `frontend/e2e/greeting-live.spec.ts` (6 tests, real browser via Playwright's `page.clock`):
-  all 8 boundary times rendered correctly in **all 3 languages** against the actual app;
-  live period rollover with no `page.reload()` call anywhere in that test; language-switch
-  behaviour without changing the time period; the "never Goedenacht" guard.
-- Live-verified on Unraid at actual current server time (2026-08-04, ~03:2x CEST, i.e. the
-  night period): dashboard showed "Welkom terug. Hier is het laatste overzicht van je
-  wagenpark." (nl-BE), "Welcome back. Here's the latest overview of your fleet." (en-GB),
-  "Bon retour. Voici le dernier aperçu de votre flotte." (fr-BE).
-
-## README / PROJECT_STATE corrections
-
-- `PROJECT_STATE.md`: fixed the stale "Product name: MobilityOps." / "PoC only"
-  locked-decisions lines (predated the Fleet Ops rebrand); fixed the "Fleet Ops
-  correction" section header, which still read "IN PROGRESS .../Not yet merged to
-  master" despite already being merged (`de0bdea` / `f780557`); appended a new dated
-  entry for this correction round (not a rewrite of prior entries, per the brief's
-  explicit instruction not to hide earlier history).
-- `README.md`: linked `docs/fleet-ops-final-localization/` alongside the existing
-  correction-round doc link; refreshed the stale Playwright test count (113 → 138 → 139
-  after the favicon regression test was added).
-
-## Backend tests, Ruff, mypy
-
-Run on the final master commit (`5f0eaa5`), local dev stack, rebuilt from source:
-
-- `pytest`: **151 passed**, 0 failed.
-- `ruff check .`: **All checks passed!**
-- `mypy app` (the project's canonical invocation, matching all prior milestone gates —
-  no `[tool.mypy]` strict config exists in `pyproject.toml`): **Success: no issues found
-  in 49 source files.**
-
-No backend Python was touched this round; these numbers are unchanged from the prior
-correction milestone's final gate, confirmed green again on the current tree.
-
-## Frontend build, Playwright
-
-- `npx tsc --noEmit`: clean, 0 errors.
-- `npm run build` (`tsc -b && vite build`): clean production build.
-- Full Playwright suite (`npx playwright test`), master build, local dev stack:
-  **139 passed**, 0 failed (confirmed on a clean run after two transient
-  `0xC0000005` Chromium worker crashes caused by this specific machine running 43+
-  concurrent Chrome processes at the time — see Known limitations; a targeted 48-test
-  re-run of every new/changed suite also passed cleanly in between).
-
-## Clean-checkout drill
-
-Isolated Compose project `mobilityops-clean` (ports 8129/1229/5679, no shared volumes/
-network with the working dev stack), fresh `git clone --branch
-fix/fleet-ops-final-i18n-ux` of only committed files:
-
-1. `docker compose build` + `up -d` from empty volumes — all 4 containers healthy.
-2. `alembic upgrade head` → `799d8800e241 (head)`.
-3. `seed --reset` → 2 users / 180 customers / 50 vehicles / 246 bookings / 75 inspections /
-   40 maintenance / 27 data-quality issues / 20 workflow runs — matches the documented
-   deterministic count exactly.
-4. Backend gates: `pytest` 151 passed, `ruff check .` clean, `mypy app` clean (49 files).
-5. Frontend: `npm ci` clean, `tsc --noEmit` clean, `vite build` clean.
-6. Full Playwright suite against the isolated stack (`MOBILITYOPS_PUBLIC_URL=http://localhost:1229`):
-   **139 passed**, 0 failed — this run covers the Dutch/English/French language checks,
-   greeting boundaries, API error paths, and the guided demo, all in one pass.
-7. Final reset + `scenario_integrity`: all 5 scenarios `ready: true`.
-8. Isolated stack, containers, volumes and images torn down; original dev environment
-   confirmed untouched (`mobilityops-*` containers unaffected throughout).
-
-**PASS.**
-
-## Guided demo per language
-
-Verified live on the Unraid deployment (`http://192.168.10.150:1236`) in all 3 languages
-via direct browser interaction: login screen role buttons, dashboard (greeting, readiness
-band, attention queue, integration pulse, recent activity), audit trail, automation retry
-flow with localized error + technical-details disclosure, and demo reset — all rendering
-correctly in nl-BE, en-GB and fr-BE. The full guided-demo Playwright spec
-(`guided-demo-full.spec.ts`) passed as part of the 139-test suite on both the local dev
-stack and the isolated clean-checkout stack.
-
-## Server deployment, container health
-
-Deployed to `http://192.168.10.150:1236` (Compose project `mobilityops`,
-`/mnt/user/appdata/mobilityops`), preserving the server's existing `.env`, the Postgres
-and n8n named volumes, the exposed port, and the deployment directory — only `api` and
-`web` were rebuilt/recreated; `db` was never touched beyond `alembic upgrade head`; no
-second n8n instance was started (shared existing n8n at `:5678` used throughout).
-
-Procedure (matching `docs/demo-release/demo-runbook.md` exactly): `git archive` → `scp` →
-extract over the existing deployment dir → update `.deploy/source-revision` →
-`docker compose -p mobilityops -f compose.yaml -f compose.unraid.yaml up --build -d api web`
-→ confirm `alembic current` → `seed --reset`.
-
-Final container status:
-
-```
-mobilityops-api-1   Up (healthy)
-mobilityops-db-1    Up (healthy)
-mobilityops-web-1   Up (healthy)
-```
-
-Deployed twice this round: once for the fix-branch tip (`09173a4`, with full live
-3-language validation), once for the final master merge commit (`5f0eaa5`) after the
-merge — both deployments passed migrations, reseed, and a live smoke test.
-
-## Repository / runtime hash comparison
-
-```
-git rev-parse HEAD (local, master)              = 5f0eaa59b032fc1e7b5e2e86d6ddd1d0f70e20d0
-/mnt/user/appdata/mobilityops/.deploy/source-revision = 5f0eaa59b032fc1e7b5e2e86d6ddd1d0f70e20d0
-```
-
-**Exact match.**
-
-## Browser console and network
-
-No console errors on any checked route in any of the 3 languages (dashboard, audit,
-automation, login) on the live Unraid deployment. All observed `/api/` network requests
-returned `200`. `api` and `web` container logs show no errors/tracebacks/exceptions after
-the final deployment.
-
-## Known limitations
-
-- **Transient `document.documentElement.lang` DOM-attribute anomaly during interactive
-  manual browser testing** on the live server: on 2 occasions, right after a client-side
-  action (an automation retry click; a demo-reset confirm click), `document.documentElement.lang`
-  briefly showed `"nl"` while the actually-rendered page content, `localStorage`, and a
-  controlled repeat of the exact same click sequence (fresh login, single deliberate
-  click, immediate inspection) all remained correctly `"fr-BE"`. Root-caused as far as
-  possible: the codebase has exactly one `i18n.changeLanguage()` call site
-  (`LanguageSwitcher.tsx`), which was not invoked in the clean repro, and `t()` /
-  `i18n.language` are structurally coupled through a single i18next singleton with no
-  code path capable of producing this split state. Not reproduced even once across 139
-  automated Playwright tests run 3 times total (local pre-merge, isolated clean-checkout,
-  local post-merge on master) in a clean, extension-free browser context. Most likely
-  explanation: a third-party browser extension active in the specific interactive testing
-  session (which also had ~10 unrelated pre-existing tabs open on the same origin, and
-  showed independent signs of instability — repeated CDP screenshot timeouts) rewriting
-  the `lang` attribute based on its own content heuristics, independent of the React app.
-  Logged here for transparency rather than silently dismissed; does not affect any
-  automated PASS result above.
-- **Two transient Chromium worker crashes** (`0xC0000005` / access violation) during the
-  master-build Playwright re-run, on a machine that had accumulated 43+ concurrent Chrome
-  processes from the interactive testing session above. A clean run immediately
-  afterward (fewer processes) passed all 139 tests; a 48-test targeted re-run of every
-  new/changed suite also passed cleanly in between. Treated as machine resource
-  contention, not a code defect — consistent with the prior correction milestone's own
-  documented experience of "sequential-run-only flakes reproduced from resource
-  contention of running two full Docker stacks at once," per `PROJECT_STATE.md`.
-- One translation gap (fr-BE `audit.columns.actor`: "Acteur" instead of the brief's
-  specified "Auteur") was missed in the initial pass and only caught during live browser
-  validation on Unraid; fixed in commit `09173a4` and redeployed before the master merge.
-- The Fleet Ops brand mark (`BrandMark` in `Icons.tsx`) was flagged by the user as
-  potentially due for a visual refresh; per explicit user decision mid-session, this is
-  out of scope for this correction round and deferred to a separate follow-up task.
-- No RAGcore/MCP Hub implementation changes were made or claimed; both remain in the same
-  demo/not-connected state documented by the prior correction milestone.
-
-## Rollback procedure
-
-`.deploy/source-revision` on the server records exactly which commit is live. To roll
-back: `ssh unraid`, extract an earlier `source-<short-sha>.tar.gz` from
-`/mnt/user/appdata/mobilityops/.deploy/` (prior tarballs remain in place, including
-`source-9468cc3e.tar.gz`, `source-09173a4.tar.gz` from this round and earlier ones from
-the prior correction milestone), update `.deploy/source-revision` to match, and re-run
-`docker compose -p mobilityops -f compose.yaml -f compose.unraid.yaml up --build -d api web`
-followed by `alembic upgrade head` (migrations are additive only — no destructive
-migration exists on this branch, so no database rollback is needed). No secrets were
-printed or read at any point in this process (`.env` was preserved byte-for-byte
-throughout, verified via unchanged file timestamp after each extraction).

-
-## Result: PASS
-
-## Commits
-
-- Original feature-branch baseline before this task: `257a4cf` (`docs(polish): audit finale demo-afwerking`)
-- Feature-branch commits added this task, on `feat/mobilityops-functional-completion`:
-  - `337f871` — polish: rebrand to Fleet Ops, add trilingual i18n, adaptive demo guide, and UX overhaul
-  - `845db14` — fix: mobile topbar overflow at 421-440px and add trilingual responsive coverage
-- Feature branch final commit: `845db14e172539b1d10e40f6a3249a72122deb41`
-- `master` before merge (verified against the previously recorded baseline): `e0c7ed60112510687627d20a957af91c8b9db7f8` — unchanged, no unexpected commits, no conflicts (confirmed via `git merge-tree` dry run before merging)

-- Feature branch was **not** deleted, per instruction.
-
-## URL
-
-- Live review deployment: `http://192.168.10.150:1236`
-
-## Visible branding
-
-- Product name "Fleet Ops" (with a space) visible in: sidebar brand lockup, browser tab title, login screen, footer product line, About page heading ("What Fleet Ops is and isn't" / "Wat Fleet Ops wel en niet is" / "Ce que Fleet Ops est et n'est pas"), demo badge popover, dashboard copy, all 3 languages.
-- No visible "MobilityOps" or "PoC"/"proof of concept" wording remains in user-facing copy (verified by full-page inspection of all main routes in all 3 languages plus a targeted source grep for stray hardcoded strings). The repository, Docker image names, and internal git history retain "MobilityOps" (out of scope; not user-visible).
-- Retained technical identifiers (unchanged, as instructed): API paths (`/api/v1/...`), Docker Compose project name (`mobilityops`), internal vehicle/customer reference prefixes (`MO-`, `CUS-`), Gitea repository name.
-
-## Supported locales
-
-- `nl-BE` (default for a fresh session, unauthenticated visitor)
-- `en-GB`
-- `fr-BE`
-- Persisted via `localStorage` key `fleetops.language`; survives refresh, logout/login, and demo reset. No flags used — accessible `<select>` language picker (visible name/code) in the topbar (desktop/tablet) and inside the mobile navigation drawer (≤960px, to avoid topbar overflow). `document.documentElement.lang` kept in sync. All dates/numbers rendered via `Intl.DateTimeFormat`/`Intl.NumberFormat` (`Europe/Brussels` timezone).
-
-## Translation coverage
-
-- `frontend/e2e/i18n-coverage.spec.ts`: recursively compares every key path across all 3 locale files for all 14 namespaces (`common, auth, navigation, dashboard, fleet, bookings, returns, quality, knowledge, integrations, audit, demo, errors, accessibility`) and fails the build on any missing key or empty string value. **2/2 passed** in every gate run this task (local, clean-checkout, and live-deployment runs).
-- Command: `npx playwright test e2e/i18n-coverage.spec.ts --project=chromium`
-
-## Knowledge-base locales
-
-- `knowledge/procedures/{nl-BE,en-GB,fr-BE}/` — 11 procedure documents per language (same `document_id`s across languages so citations stay stable): vehicle checkout, vehicle return, damage handling, odometer anomalies, cleaning checklist, maintenance escalation, customer documents, privacy, booking conflicts, roles/escalation, and a new **vehicle availability** procedure (added this task to cover the "vehicle-available-again" guided-demo step explicitly).
-- `DemoKnowledgeProvider` now retrieves per-language (only searches the UI-selected language's corpus), with localized "no match"/"low confidence" boilerplate text per language; the frontend passes the active UI language on every `/api/v1/knowledge/questions` and `/api/v1/knowledge/status` call.
-- Verified live in all 3 languages this task (see Browser evidence below): NL/EN/FR suggested questions each return grounded, correctly-cited, same-language answers.
-- Backend unit tests: `test_demo_provider_grounds_damage_question_in_dutch`, `test_demo_provider_grounds_damage_question_in_french`, `test_demo_provider_health_reports_document_count_per_language`, `test_demo_provider_insufficient_evidence_message_is_localized` — all passing.
-
-## Demo Guide — adaptive per breakpoint
-
-- **Extra-wide desktop (≥1440px)**: docked rail (`.demo-guide-panel.is-wide`), fixed 420px minimum width, no drop shadow (reads as part of the layout), never auto-collapses. Verified: `demo-guide.spec.ts` → "wide desktop viewport docks the guide as a rail that never collapses to a chip".
-- **Standard desktop/tablet (701–1439px)**: floating non-modal panel that auto-collapses to a persistent, closable progress chip ("Demo-gids · stap X van Y") the instant "Ga naar deze stap" is used; chip has its own expand action and a separate close (×) control; reopens on one click; content reflow padding shrinks to 0 while collapsed so nothing is permanently blocked. Verified: 3 dedicated tests in `demo-guide.spec.ts`.
-- **Mobile (≤700px)**: bottom sheet with collapsed / half / full states, a drag-handle button that cycles states, no horizontal overflow, primary actions (Volgende/Ga naar deze stap) reachable in the half state. Verified: `demo-guide.spec.ts` → "mobile viewport shows a bottom sheet with collapsed/half/full states and no horizontal overflow", plus `demo-accessibility.spec.ts` → "demo guide is usable as a mobile bottom sheet".
-- **Cross-cutting (4D)**: "Ga naar deze stap" scrolls the on-page target into view, moves programmatic focus to it (`tabindex=-1` + `.focus()`), and applies a 2.2s outline pulse (`.demo-guide-highlight`, disabled under `prefers-reduced-motion`); Escape collapses the standard-tier panel first, then closes it on a second press; progress (`currentIndex`/`completed`) persists in `sessionStorage` across navigation and reload. Verified: `demo-guide.spec.ts` → "Escape collapses the standard-tier panel, then closes it" and "going to a step scrolls, focuses and highlights the on-page target".
-- Fixed along the way: two dangling `aria-labelledby` references (`SectionHeading` never actually set the referenced `id`) on Dashboard and Data Quality Issue Detail panels.
-
-## Data Quality Workbench improvements
-
-- Replaced plain radio rows with accessible `.choice-card` selectable tiles (title, consequence detail, `:has(input:checked)`/`.is-selected` state, visible focus ring, hover state) across the duplicate-customer survivor choice, odometer-regression decision, and booking-overlap block choice.
-- Clear action hierarchy: primary resolve/apply/merge action uses `.button-primary`; defer uses a de-emphasized `.button-tertiary`; reject uses `.button-tertiary-destructive` (muted, turns critical-red only on hover) — no longer visually competing with the recommended resolution.
-- Technical evidence (`evidence_json`) collapsed by default behind a localized "Technical details" `<details>` disclosure.
-- Contrast/opacity audited: no unintended overlays, disabled-looking text, or weak borders found beyond the (fixed) dangling-aria-labelledby issue.
-
-## Terminology mapping
-
-- Achieved via the i18next namespace architecture itself rather than a separate module: technical codes (rule types, statuses, action codes, integration states) resolve through dedicated JSON keys (`quality:ruleTypes.*`, `quality:list.status*`, `audit:actions.*`, `integrations:statusLabels.*`, `fleet:statuses.*`, `bookings:statuses.*`) with a human label in all 3 languages; raw technical values (correlation IDs, full UUIDs, raw evidence JSON) are confined to "Technical details" disclosures. Example mappings implemented: `possible_duplicate_customer` → "Possible duplicate customer"/"Mogelijke dubbele klant"/"Client peut-être en double"; `demo_login` → "Logged in"/"Ingelogd"/"Connecté"; n8n `degraded` → "Retry available"/"Opnieuw proberen mogelijk"/"Nouvelle tentative possible"; `not_configured`/`disabled` → "Not connected"/"Niet gekoppeld"/"Non connecté".
-
-## Automation / audit improvements
-
-- Automation ledger: succeeded events group and collapse when >3 in view ("Show N succeeded jobs"/"Hide individual jobs"), filter chips (needs-attention/recent/succeeded/all), meaningful short refs (`AUT-RET-####` derived from the aggregate ref, full UUID behind a `<details>`), localized event types and statuses.
-- Audit trail: events grouped by `correlation_id` into one card with a human action-label heading (`audit:actions.*`), related-event count and an expandable technical list; readable before/after diff (`ChangeDiff` component: humanized field names, `set to`/`was`/`X → Y` phrasing) instead of raw JSON by default; short reference (`AUD-XXXXXXXX`) with full UUID and correlation ID behind "Technical details".
-
-## Attention Queue / clickable rows
-
-- Full "stretched link" pattern applied to: Attention Queue, Today's movements, Vehicles table, Bookings table, Data Quality table. Entire row is one activation target (pointer cursor, hover state, keyboard-focusable, Enter/Space activates), secondary in-row links (e.g. the vehicle reference inside a booking row) remain independently clickable via `.cell-link { z-index: 2 }` layered above the row overlay.
-- Dedicated tests in `frontend/e2e/clickable-rows.spec.ts` (8 tests): click on empty row space, keyboard focus + Enter, mobile-viewport click, secondary-link independence, correct routing for each of the 5 surfaces, pointer-cursor/focus-ring check.
-
-## Test results (all commands re-run against this exact final state)
-
-### Backend (local dev stack, clean-checkout instance, and live Unraid deployment — all three, all green)
-
-```
-docker compose exec api pytest -q            → 131 passed
-docker compose exec api ruff check .         → All checks passed!
-docker compose exec api mypy app             → Success: no issues found in 48 source files
-```
-
-### Frontend
-
-```
-cd frontend && npm run build                 → tsc -b && vite build: success
-```
-
-### Playwright (92 tests; run against local dev stack, the isolated clean-checkout stack, and the live Unraid deployment — 92/92 passed in all three runs)
-
-```
-npx playwright test --project=chromium
-```
-
-Suites: `demo-accessibility`, `demo-entry`, `demo-guide` (including the 3 new adaptive-breakpoint tests, chip close-control test, Escape test, scroll/focus/highlight test), `demo-legibility`, `demo`, `guided-demo-full`, `i18n-coverage`, `interactive-elements`, `responsive-i18n` (7 breakpoints × 3 languages = 21 tests), `ui-redesign`, `clickable-rows` (new, 8 tests).
-
-## Clean-checkout drill (evidence)
-
-Performed in an isolated environment (separate Compose project `mobilityops-clean`, separate host ports 8129/1229, no shared volumes or n8n) so the user's existing long-running dev/n8n environment was never touched:
-
-1. `git clone` of the local repository at commit `845db14` (feature branch, pre-merge) into a scratch directory.
-2. `cp .env.example .env` (project name and ports overridden for isolation only).
-3. `docker compose up --build -d db api web` — migrations ran automatically on API startup.
-4. `docker compose exec api python -m app.cli seed --reset` — deterministic seed loaded (users:2, customers:180, vehicles:50, bookings:246, inspections:75, maintenance:40, data_quality_issues:26, workflow_runs:20).
-5. `docker compose exec api pytest -q` → 131 passed. `ruff check .` → clean. `mypy app` → clean.
-6. `npm ci && npm run build` → clean build.
-7. `npx playwright test --project=chromium` (pointed at the isolated stack via `MOBILITYOPS_PUBLIC_URL`) → 92 passed.
-8. Live browser verification in English and French (Dutch already covered as the automated-suite default): guided-demo dashboard, knowledge-assistant grounded answers in both languages with correct same-language citations.
-9. `POST /api/v1/demo/reset` → `scenario_integrity: {"all_ready": true, "not_ready": []}`.
-10. Isolated stack torn down (`docker compose down -v`) — original dev environment (containers, n8n owner account/workflows) confirmed untouched and healthy throughout.
-
-No PASS was claimed from pre-existing containers at any point — every gate above ran against a stack built from empty volumes.
-
-## Server deployment evidence
-
-- Deployed via the established safe method: `git archive` from the exact commit → `scp` to `.deploy/source-<sha>.tar.gz` on Unraid → extract → update `.deploy/source-revision` → `docker compose -p mobilityops -f compose.yaml -f compose.unraid.yaml up --build -d api web` (db never rebuilt; server `.env` and named volumes — Postgres, n8n — preserved throughout).
-- Deployed twice this task: once for the feature branch (`845db14`) for pre-merge live validation, once for the merged `master` (`18a765d`) for the final release.
-- Post-deploy, both times: migrations confirmed at head (`e7b08389f47f`), reseed run, `pytest`/`ruff`/`mypy` re-run in the container (all green), full 92-test Playwright suite re-run against the live URL (all green), console/network inspected via live browser (no errors, all `/api/*` calls 200), demo reset performed, `scenario_integrity.all_ready: true` confirmed both times.
-- Real shared n8n instance (`http://192.168.10.150:5678`) integration confirmed live: the seeded failed-demo automation event correctly shows "Retry available"/"Opnieuw proberen mogelijk" (not the raw `degraded` string) on the Integration pulse card.
-
-## Responsive / accessibility
-
-- No-horizontal-overflow verified across the full 7-breakpoint matrix (1440×1000, 1280×800, 1024×768, 768×1024, 430×932, 390×844, 360×800) in all 3 languages (`responsive-i18n.spec.ts`, 21 tests) plus the original 4-breakpoint English suite (`ui-redesign.spec.ts`).
-- Real bug found and fixed during this pass: the new topbar language switcher pushed the 421–440px range into horizontal overflow (the existing "compact topbar" breakpoint stopped at 420px). Fixed by widening that breakpoint to 440px; re-verified clean at exactly 430px in all 3 languages.
-- Focus-visible outlines, `prefers-reduced-motion` handling (demo-guide highlight pulse, bottom-sheet height transitions), and keyboard reachability verified via `demo-accessibility.spec.ts` and the new adaptive-guide/clickable-row tests.

-## Known limitations
-
-- Data-quality evidence "summary" strings (the free-text detail line under each Attention Queue/Data Quality row, e.g. "exact email; exact phone; similar name") remain English-only — these are generated deep in the deterministic rule engine as diagnostic strings, not yet converted to message codes. The rule-type label, status, and all surrounding UI are fully localized; only this one diagnostic fragment is not. Documented as a follow-up, not blocking.
-- RAGcore and ITWorx MCP Hub remain honestly labelled as not live-connected (unchanged from prior milestones) — the demo knowledge base is the multilingual, fully-verified stand-in.
-- Vehicle/customer internal reference prefixes (`MO-`, `CUS-`) were left unchanged; they are generic internal codes, not user-visible "MobilityOps" branding, and changing them was out of scope for this task.
-- Automated live-browser evidence for the guided demo was captured in Dutch (via the automated Playwright suite, which defaults to the app's own nl-BE default) and manually spot-checked live in English and French (knowledge assistant, dashboard, About page); a full manual click-through of all 8 guided-demo steps was not repeated live in all 3 languages beyond the automated `guided-demo-full.spec.ts` (Dutch) and the targeted EN/FR checks documented above, given the exhaustive automated coverage already exercising the same code paths per language via `responsive-i18n.spec.ts` and `i18n-coverage.spec.ts`.
-
-## Rollback procedure
-
-- `.deploy/source-revision` on Unraid records the exact deployed commit (`18a765d62345ea9a6660d04fb868f218cf4d0b6e`).
-- Prior tarballs remain in `.deploy/` on the server, including `.deploy/source-845db14.tar.gz` (feature branch, pre-merge) and `.deploy/source-4a268c7.tar.gz` (previous release, pre-polish).
-- To roll back: extract the desired `source-<short-sha>.tar.gz`, update `.deploy/source-revision` to match, and re-run `docker compose -p mobilityops -f compose.yaml -f compose.unraid.yaml up --build -d api web`. Database migrations on this branch are additive only; no destructive migration was introduced.

-
-## Demo users and access method
-
-Two fixed seeded identities, selected via the login screen's role buttons (no
-password): **Amelie De Ridder** (`USR-OPS`, Operations Manager) and **Karim
-Boujaddaine** (`USR-EMP`, Rental Employee). `POST /api/v1/demo/login` issues an
-HttpOnly, `SameSite=Lax` signed session cookie; `GET /api/v1/demo/session` (marked
-`Cache-Control: no-store`) is what the browser actually trusts on every load, not a
-locally cached copy.
-
-## Implemented functionality (this pass, on top of the already-accepted M0–M7/design baseline)
-
-- Fixed two confirmed defects: Vehicles and Bookings both computed a filtered/paginated
-  result but rendered the raw array.
-- Server-backed session lifecycle (`GET /demo/session`, `POST /demo/logout`), central
-  401 handling, no more `sessionStorage`-as-authority.
-- A role matrix enforced server-side (403 on every manager-only action for Rental
-  Employee, not just a hidden button) and mirrored in the nav/route guards.
-- Authoritative, non-mutating return preview (`POST /bookings/{ref}/return-preview`)
-  sharing its evaluation function with commit — fixed a real bug where the frontend's
-  guessed preview text was wrong (damage → described as "maintenance", actual rule
-  "blocked"; the no-contradiction case → described as "available", actual rule always
-  "cleaning" first).
-- Audit API/UI now expose `before`/`after` (the columns existed but were never
-  serialized) plus a resolved safe entity link.
-- Typed related-entity snapshots (booking_overlap's related refs are bookings, not
-  vehicles — previously silently unresolved) and a bounded resolution flow for every
-  one of the five data-quality rule types, plus an audited manual scan trigger and
-  documented recurrence linking (`reopened_from`/`previous_decision`).
-- Role-aware backend search (`GET /api/v1/search`) replacing a blind client-side regex
-  guesser, with a real results panel, keyboard navigation and debouncing.
-- A safe, confirmed demo-reset UI trigger (the endpoint already existed and was
-  already gated).
-- Truthful aggregate n8n integration status (`GET /api/v1/integrations/status`) from
-  outbox delivery counts, replacing a single-most-recent-event read; fixed
-  `MCP_HUB_REGISTRATION_ENABLED` being declared in `.env.example` but never wired into
-  `Settings`.
-- Bounded outbox delivery-lease recovery for a process crash between claim and outcome.
-- A second n8n workflow (scheduled quality scan), independent of RAGcore/MCP Hub.
-
-## RAGcore integration status
-
-Unchanged from the prior baseline and honestly reported throughout: the demo
-`KnowledgeProvider` (deterministic TF-IDF extractive retrieval over local procedure
-documents) satisfies the knowledge-assistant acceptance criteria and is fully verified.
-A `RAGcoreKnowledgeProvider` HTTP adapter is implemented and unit-tested (including its
-unavailable-degradation path) but was never exercised against a live RAGcore instance in
-this environment — no live RAGcore instance exists to test against.
-`KNOWLEDGE_PROVIDER=demo` on the Unraid deployment; no simulated live connection is ever
-shown.
-
-## MCP Hub integration status
-
-The four read-only provider endpoints are implemented, tested, and directly
-curl-verified with correct service-token auth enforcement and audit logging.
-`MCP_HUB_REGISTRATION_ENABLED` — previously declared in `.env.example` but silently
-dropped by `extra="ignore"` since it had no `Settings` field — is now actually wired in
-and honestly reported (`GET /api/v1/integrations/status`'s `mcp_hub.state`). It is
-`false` on the Unraid deployment (`state: "not_configured"`). No live Hub instance was
-reachable in this environment to verify an actual Hub round trip.
-
-## n8n integration status
-
-Fully implemented and live-verified. The original return-processing workflow: verified
-against both the local bundled instance and the shared Unraid instance, including a real
-degraded-mode drill in an earlier session (n8n stopped mid-flow → return still committed
-locally, event stayed `pending` with backoff, self-healed once n8n returned) and the
-manual-retry path. This pass adds:
-
-- **Truthful status**: `GET /api/v1/integrations/status` derives n8n health from
-  aggregate outbox counts (pending/delivering/succeeded/failed), not the single most
-  recent event.
-- **Stale-delivery-lease recovery**: a claimed-but-never-resolved `delivering` row (the
-  process crashing between claim and outcome) is now recoverable; unit-tested including
-  a simulated crash, and confirmed a still-alive worker's unexpired lease is never
-  touched.
-- **Second workflow**: `mobilityops-scheduled-quality-scan` (hourly + manual-test
-  trigger, ships `"active": false"`), calling `POST
-  /api/v1/integrations/n8n/scheduled-scan`. Live-verified two ways: (1) executed
-  end-to-end via the Manual test trigger against the **local** n8n instance — full
-  green execution in the n8n editor, confirmed by the resulting
-  `data_quality_scan_run` audit event (`actor_type=service`); (2) published to the
-  **shared Unraid n8n** via `deploy/unraid/setup-scheduled-scan.sh` and the resulting
-  endpoint directly curl-verified against the live deployed API, also confirmed via the
-  audit trail. The shared instance's own UI could not be browser-tested directly — it
-  runs `N8N_SECURE_COOKIE=true` and refuses login over the plain-HTTP LAN URL used for
-  automated testing here, which is correct, pre-existing shared-infrastructure
-  behaviour and out of scope to change.
-
-## Known limitations
-
-- RAGcore and ITWorx MCP Hub remain honestly not-live-connected — no live instance of
-  either exists in this environment (environment limitation, not a code defect).
-- `npm audit`: one moderate esbuild/Vite dev-server-only advisory (fix requires a Vite
-  major upgrade, deliberately deferred), and a
-  react-router RSC-mode advisory that doesn't apply (the app never uses RSC/SSR mode) —
-  both pre-existing, confirmed unchanged by this pass's clean `npm ci`.
-- Demo authentication remains the accepted HMAC-cookie PoC mechanism tied to two fixed
-  seeded identities — not a production identity provider.
-- The scheduled quality-scan workflow's own n8n-engine execution was verified live
-  against the local bundled n8n and, for the HTTP round trip specifically, against the
-  shared Unraid n8n's resulting API call — not against a full n8n-engine execution *on
-  the shared instance itself*, for the browser-access reason above.
-- `n8n_delivery_lease_seconds` (120s default) is a code-level tunable, not exposed in
-  `.env.example`, consistent with the existing `n8n_dispatch_interval_seconds`/
-  `n8n_max_attempts`/`n8n_http_timeout_seconds` tunables already handled that way.

-## Clean deployment instructions
-
-See `deploy/unraid/README.md` and `docs/17-runbook.md` for the full runbook. Redeploy
-the exact committed revision:
-
-```bash
-COMMIT=<commit to deploy>
-git archive --format=tar.gz --output=/tmp/source.tar.gz "$COMMIT"
-scp -P 22 /tmp/source.tar.gz unraid:/mnt/user/appdata/mobilityops/.deploy/source.tar.gz
-ssh unraid "cd /mnt/user/appdata/mobilityops \
-  && tar -xzf .deploy/source.tar.gz \
-  && echo $COMMIT > .deploy/source-revision \
-  && docker compose -p mobilityops -f compose.yaml -f compose.unraid.yaml up --build -d db api web \
-  && docker compose -p mobilityops -f compose.yaml -f compose.unraid.yaml exec -T api alembic current \
-  && curl -fsS http://127.0.0.1:1236/health"
-```
-
-`.env` and both named volumes (`mobilityops-db`, `mobilityops-n8n`) are preserved by
-this flow; nothing outside the `mobilityops` Compose project is touched.
-
-## Five-minute demonstration flow
-
-1. Open `http://192.168.10.150:1236`, log in as **Operations Manager**.
-2. Dashboard: point out the persisted readiness metrics and the now-truthful n8n
-   integration-status card (aggregate counts, not just the latest event).
-3. Global search (`Ctrl/Cmd+K`): type a vehicle, booking or issue reference; use arrow
-   keys + Enter to navigate; show the no-results state for a nonsense query.
-4. Bookings: filter by status, page through results (max 25/page), confirm page 2
-   differs from page 1.
-5. Open an active booking → capture a return with a below-canonical odometer reading →
-   the review step shows the server's authoritative evaluation (odometer regression
-   flagged, resulting status and reason) → confirm → result screen distinguishes local
-   commit success from queued-not-yet-confirmed n8n delivery, links to the created
-   data-quality issue.
-6. Data quality: run a manual scan; open the newly flagged (or an existing) issue for
-   each rule type and show its dedicated bounded resolution flow (not raw JSON).
-7. Audit trail: filter by the correlation ID from the return above; show the
-   human-readable before/after change summary, expand the raw-JSON `<details>`.
-8. Switch role to **Rental Employee**: show Data Quality/Integrations/Audit are absent
-   from the nav, and that direct URL navigation to any of them shows the restricted
-   message rather than partial data or a crash.
-9. Switch back to Operations Manager, trigger **Reset demo data** with confirmation,
-   land back at login, log in again to confirm deterministic data was restored.

-## Commit
-
-Built on branch `feat/live-n8n-ragcore-integration`, HEAD at commit
-`aaa16305354d34f9c1f4d57253d33d9062c38faa` ("docs: record WF2 retry fix and WF4's
-n8n-session-expiry blocker"). Run `git log --oneline feat/live-n8n-ragcore-integration`
-for the full history of this effort.
-
-## Scope
-
-The brief required treating n8n (`https://n8n.itworx.tech`) as a full third integration
-layer alongside RAGcore and MCP Hub, with Fleet Ops keeping exclusive ownership of
-business rules, authorization, transactions, audit, and idempotency. Four canonical n8n
-workflows were required. The repository (`n8n/workflows/*.json` + `MANIFEST.md` +
-`n8n/workflows/check_drift.py`) is the source of truth for cleaned workflow definitions;
-the Fleet Ops integration status page (`/automation`) shows real per-workflow operational
-evidence, not a config boolean.
-
-## Result summary
-
-| # | Workflow | Status | Live evidence this round |
-|---|---|---|---|
-| 1 | Fleet Ops — Vehicle Return Orchestration | **Live, hardened** | Timeout+bounded-retry gap found and fixed |
-| 2 | Fleet Ops — Scheduled Data Quality Scan | **Live, hardened** | Same gap found and fixed |
-| 3 | Fleet Ops — RAGcore Procedure Sync | **Blocked** | Not built — RAGcore rejects credential issuance (see below) |
-| 4 | Fleet Ops — Workflow Error Handler | **Live, validated** | Mock + genuine induced-failure test; own hardening incomplete (see below) |
-
-Full per-workflow detail (purpose, trigger, event contract, required credentials, live
-workflow ID, checksum) is in `n8n/workflows/MANIFEST.md`, which is the authoritative,
-continuously-updated source — this document is a point-in-time summary of that state
-plus the reasoning behind what's not done.
-
-## Workflow 1 — Vehicle Return Orchestration
-
-Live workflow ID `mobilityops-return-processing`. Validated in an earlier round of this
-effort: webhook trigger requires Header Auth (`Fleet Ops Webhook Trigger Token`),
-validates `event_type == vehicle.returned.v1`, derives a follow-up category, calls Fleet
-Ops's `/return-callback` endpoint with an `Idempotency-Key` header via a named
-`Fleet Ops Service Token` credential (not a literal secret), and responds with a
-controlled JSON result. Idempotent on both sides (`event_id` flows through as the
-dedup key; the backend independently checks for a prior audit event before recording
-again).
-
-**This round's finding**: the `Record follow-up` HTTP node had no explicit timeout and
-"Retry On Fail" disabled — a real gap against the requirement that external dependencies
-have timeouts and bounded retries. Fixed live: Retry On Fail (3 tries, 1000ms wait) + a
-15000ms timeout, published. Safe to retry because the callback is idempotent. Repo
-definition and manifest checksum synced (commit `0562893`).
-
-Attached to workflow 4 as its Error Workflow.
-
-## Workflow 2 — Scheduled Data Quality Scan
-
-Live workflow ID `mobilityops-scheduled-quality-scan`. Validated earlier: hourly
-Schedule Trigger + a Manual Trigger for on-demand testing, both feeding a single HTTP
-call to Fleet Ops's `/scheduled-scan` endpoint (Header Auth via the same `Fleet Ops
-Service Token` credential, 15000ms timeout already configured), which runs the
-domain-level `run_scan()` function — documented and tested as idempotent by
-construction (only ever creates an issue for a condition that doesn't already have one
-open), so overlapping or retried triggers do no duplicate domain work.
-
-**This round's finding**: the same Retry On Fail gap as workflow 1 (timeout was already
-set, retries were not). Fixed live the same way (3 tries, 1000ms wait), published. Repo
-definition and manifest checksum synced (commit `167bf49`).
-
-Attached to workflow 4 as its Error Workflow.
-
-## Workflow 3 — RAGcore Procedure Sync — blocked
-
-**Not built.** This workflow needs an application credential (scope `sources:sync`) for
-the `fleet-ops` application in RAGcore. Two independent issuance attempts, in two
-separate rounds of this effort, both failed with an opaque server-side rejection:
-
-1. **Raw API**: `POST /v1/applications/{id}/credentials` → `400`, "authoritative
-   service-account state rejected issuance".
-2. **RAGcore admin UI**, this round, after the project owner explicitly authorized
-   Claude to self-issue the credential: the "Issue credential" form for the `fleet-ops`
-   application, submitted as the Platform Admin role (the highest role visible in the
-   RAGcore admin), with name `n8n-ragcore-procedure-sync` and scope `sources:sync` only.
-   Result: "Something went wrong. The credential could not be issued with those
-   values.", trace reference `1955c6a8968c4941a22a1faef39e17a7`.
-
-The `fleet-ops` application itself shows as ordinary/`Active` in the RAGcore admin, with
-no visible lock flag, and RAGcore's own OpenAPI spec documents no validation rule that
-would explain either rejection (no `422`, no field-level errors). Two independent paths
-— a raw API call and the admin UI as the top admin role — hitting the same failure
-signature is conclusive evidence this is a RAGcore-side policy or bug, not a Fleet Ops
-request-shape or permission problem. It is not fixable from the Fleet Ops side or
-through further UI automation. Resolving it requires whoever operates the RAGcore
-instance to look up the trace ID above (and the earlier raw-API rejection) in RAGcore's
-own logs.
-
-The real RAGcore contract this workflow will be built against — once a working
-credential exists — was independently inspected via RAGcore's live OpenAPI spec and is
-recorded in `docs/live-ai-integration/n8n-current-state.md` and
-`contracts/ragcore-contract-assumptions.md`: control-plane endpoints require an
-`Idempotency-Key` header; ingestion is `POST /v1/uploads`; retrieval is `POST
-/v1/search` / `/v1/context` / `/v1/answers` (the latter requiring `requested_space_ids`,
-an array of knowledge-space UUIDs); health is `/health/live` and `/health/ready` (not
-`/health`); the scope enum is `search, context, answer, documents:read, citations:read,
-feedback:write, sources:sync`.
-
-**`RAGcoreKnowledgeProvider` adapter** (`backend/app/services/knowledge/ragcore.py`)
-still targets the earlier speculative contract (`/health`, `POST /api/v1/ask`, Bearer
-token) rather than the real one above. This was deliberately **not** rewritten this
-round: rewriting it blind, without a credential to validate against, risks introducing
-a silent behavioral bug in exactly the code path responsible for the project's "AI must
-never invent an answer when RAGcore is unavailable or returns insufficient evidence"
-guarantee — for example a wrong `evidence_state` mapping that looks fine in code review
-but misclassifies "unavailable" as "insufficient" (or vice versa) against the real
-response shape. The adapter's current behavior is honest and safe (it degrades cleanly
-to `unavailable` on any request or parsing failure, and `ragcore_api_token` is unset by
-default so the app correctly runs on the local demo knowledge provider today). The
-rewrite stays queued behind the same credential blocker as workflow 3.
-
-## Workflow 4 — Workflow Error Handler
-
-Live workflow ID `Xppn2rAEqUuyiCJF`. Built and live-validated in an earlier round:
-Error Trigger → a Code node that derives a bounded, secret-free failure report (error
-category classified from the message text, truncated summary, no stack trace, no
-headers or tokens) → an HTTP call to Fleet Ops's `/workflow-error` endpoint (Header Auth
-via the same `Fleet Ops Service Token` credential), which registers the failure as an
-audit event idempotently keyed on `execution_id`.
-
-Set as the Error Workflow on both workflow 1 and workflow 2. Confirmed workflow 4 has no
-Error Workflow of its own (prevents a recursive loop).
-
-**Live validation performed**: a pinned mock Error Trigger payload produced a real `200
-{"status":"registered", ...}` from the live Fleet Ops server; re-running the identical
-payload produced `"status":"already_registered"`, confirming idempotency. A genuine
-induced failure (temporarily pointing workflow 2's HTTP node at a nonexistent path, then
-reverting) confirmed workflow 2 itself fails correctly against a broken endpoint and
-recovers cleanly once reverted.
-
-**Known limitation**: n8n's Error Workflow trigger does not fire for manual editor
-"Execute workflow" test runs — checked via workflow 4's own Executions list after the
-induced workflow-2 failure, and confirmed no new execution appeared. n8n only invokes a
-workflow's assigned Error Workflow for unattended/production trigger executions, not
-manual test runs from the editor. The mock-data path exercises the same nodes, logic,
-and real Fleet Ops endpoint, but a fully automatic (schedule- or webhook-triggered)
-failure cascading into workflow 4 was not observed live in either round.
-
-**Open follow-up (minor, non-blocking)**: continuing this round's acceptance pass to
-workflow 4 found the same timeout/retry gap as workflows 1 and 2 on its own outbound
-HTTP call. A fix was started (15000ms timeout added, Retry On Fail toggled on) but n8n's
-autosave began failing with "Unauthorized" mid-edit; a fresh browser tab confirmed the
-n8n session had expired (redirected to `/signin`). Nothing was saved — workflow 4's live
-definition is unchanged from before this round, so there is no partial or broken state.
-This is lower-stakes than workflows 1/2 (workflow 4 is the error notifier itself, not a
-primary business flow, and a failed error-report is already visible in n8n's own
-execution history via `On Error: Stop Workflow`) but should be finished once the n8n
-browser session is re-authenticated.
-
-## Repository source of truth
-
-`n8n/workflows/` holds cleaned, credential-value-free JSON definitions for all built
-workflows, `n8n/workflows/MANIFEST.md` documents purpose/trigger/contract/credentials/
-live-ID/checksum for all four canonical workflows (including workflow 3's blocked
-status), and `n8n/workflows/check_drift.py` is a read-only script that compares the
-repo definitions against the live instance via n8n's Public API and reports drift —
-safe to run in CI as a non-blocking check. No literal export/download mechanism was
-found working in this n8n version, so each definition was reconstructed from direct,
-verified UI inspection rather than a native export; this limitation is noted in the
-manifest itself.
-
-## Integration status page
-
-`/automation` (Operations Manager only) surfaces real per-workflow evidence derived
-purely from Fleet Ops's own audit/outbox tables — no new dependency on n8n's API was
-added to the backend. Each of the four canonical workflows shows a status (not built /
-no evidence yet / operational) and a last-evidence timestamp; the scheduled-scan
-evidence specifically filters to `actor_type == "service"` so a manually-triggered scan
-in the UI doesn't count as n8n evidence. An error-handler summary line reports total
-registered automation failures and the most recent one.
-
-Verified live in the browser (Dutch locale) both locally and on the deployed
-production server (`http://192.168.10.150:1236/automation`): correctly showed "3 van 4
-canonieke n8n-workflows hebben actuele evidentie van werking" with real timestamps for
-the return/scan/error-handler workflows, "Nog Niet Gebouwd" for the RAGcore sync, and
-the real error-handler registration from this effort's live testing.
-
-## Deployments performed (all explicitly user-approved)
-
-1. Backend `/workflow-error` endpoint (commit `bbdb4a9`) — deployed and verified
-   (`/health` OK, new endpoint returns `422` not `404` on an empty POST body).
-2. Integration status page, backend + frontend (commit `4049c0c`) — deployed and
-   verified (`/health` OK, page renders real evidence in the browser).
-
-The three n8n-side node edits this round (WF1 timeout/retry, WF2 timeout/retry, WF4's
-incomplete attempt) are live edits to the n8n instance itself and do not require a
-Fleet Ops redeploy.
-
-## What's left
-
-1. **RAGcore credential issuance** — blocked on RAGcore's own server-side rejection
-   (trace `1955c6a8968c4941a22a1faef39e17a7` and the earlier raw-API `400`). Needs
-   RAGcore's operator to investigate. Unblocks workflow 3 and the
-   `RAGcoreKnowledgeProvider` real-contract rewrite.
-2. **Workflow 4's own timeout/bounded-retry hardening** — needs the n8n browser session
-   re-authenticated to finish; a small, well-understood, non-blocking edit.
-3. **Fleet Ops logo/favicon** — explicitly deferred by the project owner as a separate,
-   unrelated follow-up task, not part of this integration effort.

 # Unraid deployment
 
-MobilityOps is deployed from a committed source archive; the server does not need Gitea
-credentials. The portable `compose.yaml` is combined with `compose.unraid.yaml`; of the
-MobilityOps-owned services, only the web application is reachable from the LAN. The host's
-existing shared n8n remains available on its established port 5678.
+MobilityOps is deployed from a committed source archive; the server does not need Gitea credentials. The portable `compose.yaml` is combined with `compose.unraid.yaml`. Of the MobilityOps-owned services, only the web application should be reachable from the trusted network. PostgreSQL and the API remain on the Compose network.
+
+All hostnames, ports, paths and public domains below are operator-controlled configuration. Do not commit a production `.env`, SSH target or infrastructure inventory.
 
 ## Server layout
 
-- Directory: `/mnt/user/appdata/mobilityops`
-- Compose project: `mobilityops`
-- Public web: `https://fleetops.itworx.tech` (TLS reverse proxy to host port `1236`)
-- API and PostgreSQL: Compose network only
-- Shared n8n: `http://192.168.10.150:5678` (outside the MobilityOps Compose project)
+Define a local appdata root and URLs before following the examples:
+
+```bash
+export MOBILITYOPS_APPDATA_DIR=/mnt/user/appdata/mobilityops
+export MOBILITYOPS_PUBLIC_URL=https://fleetops.example.com
+export N8N_BASE_URL=https://automation.example.com
+```
+
+The `/mnt/user/appdata/...` value is an illustrative Unraid convention, not a repository requirement. Use a different persistent directory where appropriate.
+
+- application directory: `${MOBILITYOPS_APPDATA_DIR}`;
+- Compose project: `mobilityops`;
+- public web URL: `${MOBILITYOPS_PUBLIC_URL}`;
+- API and PostgreSQL: Compose network only;
+- shared n8n: `${N8N_BASE_URL}`, outside the MobilityOps Compose project.
+
+## Configure
+
+Create `.env` from `.env.example`, replace every placeholder secret and set:
+
+```dotenv
+MOBILITYOPS_ENV=production
+MOBILITYOPS_PUBLIC_URL=https://fleetops.example.com
+MOBILITYOPS_API_PUBLIC_URL=https://fleetops.example.com/api
+N8N_WEBHOOK_URL=https://automation.example.com/webhook/mobilityops-return
+SESSION_COOKIE_SECURE=true
+```
+
+Configure `KNOWLEDGE_PROVIDER=ragcore` only after the RAGcore health and source-inventory checks pass. When RAGcore runs as a separate Compose project on the same host, keep its HTTP listener private and configure Fleet Ops through a shared Docker network, for example:
+
+```dotenv
+RAGCORE_BASE_URL=http://ragcore-app:8080
+RAGCORE_DOCKER_NETWORK=ragcore-proxy
+```
+
+The release deployer takes non-secret integration URLs from the server `.env` on every promotion. Tokens and resolved API environment remain server-side and must not be printed.
 
 ## Deploy
 
-Create `.env` from `.env.example`, replace every placeholder secret, set
-`MOBILITYOPS_ENV=production`, set both public URLs to
-`https://fleetops.itworx.tech`, set `SESSION_COOKIE_SECURE=true`, and configure
-`KNOWLEDGE_PROVIDER=ragcore` only after the RAGcore health and source inventory checks pass.
-The internal `1236` listener is
-an upstream for the TLS proxy, not a user-facing URL.

+Flag a newly recorded checkout, return-inspection or maintenance reading below the
