 # Fleet Ops
-**Connected operations for vehicle rental and service teams.**
+**A recruiter-ready operations platform for vehicle rental and service teams.**

 knowledge base, and this documentation. "MobilityOps" remains the technical
 identifier only — the repository name, local directory, package/module names, Docker
 Compose project, deployment directory, and database names. The UI is fully trilingual
 (nl-BE default, en-GB, fr-BE); see `docs/fleet-ops-correction/` for the localization
 architecture, the vehicle-status decision table, and the correction evidence, and
 `docs/fleet-ops-final-localization/` for the follow-up correction round (remaining
 NL/FR translation gaps, centralized API-error localization, the time-dependent
 Europe/Brussels dashboard greeting).
-The web application uses the premium responsive **Control Rail** interface: a compact

+## What makes it more than a mock-up
 rental company — the login screen, a permanent "Synthetische demo" indicator, an in-app
 guided tour (Demo Guide), a curated `/scenarios` overview, and an "Over deze demo" page
 all make the fictional context, synthetic-data status, and real-vs-simulated boundaries
 explicit without any verbal explanation. See `docs/demo-release/` for the full demo
 concept, the five named scenarios, the seed/date-anchoring strategy, the guided-tour
 design, and the operational runbook (5-minute and 10-minute demo flows, reset, redeploy,
 rollback).
-## Scope
+- **Transactional operations:** a return writes the inspection, vehicle/booking state, audit events and outbox record atomically. n8n downtime never rolls back the local business transaction.
 - **Explainable data quality:** five persisted rule types, SLA deadlines, assignment, bulk queue controls and bounded resolution flows—not decorative warning cards.
 - **Grounded knowledge:** the live deployment uses RAGcore; insufficient or unavailable evidence produces no invented answer. Citations and provider provenance remain inspectable.
 - **Safe AI exposure:** four tenant-bound, service-authenticated, read-only Fleet Ops tools are published through ITWorx MCP Hub and audited with correlation IDs.
 - **Operational reliability:** bounded retries, delivery leases, health/readiness, Prometheus metrics, Grafana, scheduled verified backups and graceful external-dependency degradation.
 - **Real product ergonomics:** nl-BE, en-GB and fr-BE; responsive from 360 px; keyboard-accessible navigation; role-aware global search; route-level lazy loading; server-enforced permissions.
-The PoC implements:

 - deterministic demo reset and five-minute showcase.

+Fleet Ops owns operational truth. RAGcore owns retrieval, n8n performs post-commit orchestration, and MCP Hub owns tool transport/publication. Neither RAGcore nor MCP Hub accesses the Fleet Ops database directly. See [the as-built architecture](artifacts/evidence/architecture.md).
-## Integration status
+## Demonstrable scope
- **n8n**: fully implemented and verified against a real n8n instance, including
+- dashboard, vehicle fleet, booking lifecycle and controlled returns;
-  degraded mode (n8n stopped mid-flow → return still commits, event stays `pending`
+- data-quality queue, assignment, review, merge and resolution;
-  with backoff, self-heals once n8n returns), the failed-delivery manual-retry path,
+- correlated human-readable audit history;
-  stale-delivery-lease recovery after a simulated crash, and a second (scheduled
+- cited Knowledge Hub with honest provider state;
-  quality-scan) workflow live-verified end to end against a real n8n instance.
+- n8n delivery monitoring and manual retry;
-  `GET /api/v1/integrations/status` reports a truthful aggregate state from outbox
+- user administration, privacy export/anonymisation and retention guards;
-  delivery counts, not just the most recent event.
+- deterministic reset with 2 users, 180 customers, 50 vehicles, 254 bookings, 75 inspections, 40 maintenance records, 33 quality issues and 20 workflow runs.
 - **RAGcore**: the live deployment uses `KNOWLEDGE_PROVIDER=ragcore`. Readiness and real
  grounded retrieval are verified end to end; when RAGcore's generated-answer endpoint
  is unavailable, Fleet Ops falls back only to cited extractive search results and never
  invents an answer. The deterministic demo provider remains available for clean-checkout
  acceptance and local development.
 - **ITWorx MCP Hub**: the four read-only provider endpoints are implemented, tested, and
  directly `curl`-verified with correct auth enforcement and audit logging.
  `MCP_HUB_REGISTRATION_ENABLED` is actually wired into `Settings` and reported honestly
  by the integration-status endpoint (evidence-based: real tool-call audit history, not
  just the flag). The Fleet Ops connector is confirmed live in the ITWorx MCP Hub's own
  production deployment (Tower), with a real contract fix already applied there
  (`vehicle.get`'s wire parameter normalized to `vehicleRef`).

-# Portfolio case-study template
+# Fleet Ops — portfolio case study
-## Title
+## Product
-MobilityOps — connected operations for vehicle rental and service teams
+Fleet Ops is a working operations platform for a fictional Belgian mobility company. It unifies vehicle and booking work, makes data defects resolvable, automates post-return follow-up and turns internal procedures into cited answers.
 ## One-sentence summary
 A working synthetic-data PoC that unifies vehicle and booking operations, automates vehicle returns, surfaces data-quality problems and exposes grounded internal knowledge through reusable RAG and MCP platforms.
 ## Problem
-Operational information was modelled as fragmented across booking, vehicle and procedure sources, causing manual checks, inconsistent states and slow access to instructions.
+Rental operations often span booking records, vehicle state, inspections and separate procedure documents. The difficult part is not another dashboard; it is preserving one trustworthy state while people, automation and AI consume the same workflow.
-## Approach
+## Engineering approach
- MobilityOps owns canonical operational data and business rules.
+- Keep business invariants in a FastAPI/SQLAlchemy domain layer backed by PostgreSQL constraints and row locks.
- A transactional return workflow persists inspections, derives status and queues post-commit orchestration.
+- Commit vehicle returns, audit evidence and an outbox message in one transaction.
- Explainable rules detect duplicates, mileage regressions, overlaps, missing fields and status conflicts.
+- Let the existing central n8n execute secondary work asynchronously, with leases, retries and authenticated callbacks.
- RAGcore provides source-grounded procedure answers.
+- Detect five classes of data-quality issue and require bounded, explicit human resolution.
- ITWorx MCP Hub exposes narrowly scoped read-only AI tools.
+- Integrate RAGcore through a provider adapter that refuses unsupported answers and preserves citation provenance.
- n8n orchestrates secondary processing without becoming the business-rule engine.
+- Publish only four narrow read-only tools through ITWorx MCP Hub; never give external AI systems database access.
 - Expose correlation-based evidence in the product so architecture claims can be inspected, not merely read in a diagram.
-## Demonstrable results
+## Demonstrable result
-Use only facts actually measured in the final build, such as:
+- 50 vehicles, 180 customers and 254 bookings in a deterministic synthetic dataset;
 - one complete controlled return workflow and five persisted quality-rule types;
 - 11 authoritative Dutch procedure sources with localized grounded retrieval;
 - four tenant-bound, service-authenticated read-only MCP tools;
 - trilingual responsive UI, server-backed roles, global search, privacy controls and audit;
 - degraded-mode coverage for n8n and RAGcore, production health/metrics and verified backups;
 - complete backend and browser acceptance recorded in `artifacts/evidence/final-summary.md`.
- 50 deterministic synthetic vehicles and 245 bookings;
+## Product decisions worth discussing
 - five automated data-quality rule types;
 - one end-to-end return workflow;
 - ten versioned source procedures;
 - four read-only MCP tools;
 - tested degraded modes for RAGcore and n8n.
-Do not claim real customer adoption, production use or percentage time savings.
+**Why an outbox?** A return must remain committed when n8n is unavailable. Persisting the event in the same database transaction closes the gap between business success and later orchestration.
 **Why no generative fallback?** A fluent procedure answer without evidence is worse than a clear unavailable state. Knowledge answers require cited provider evidence.
 **Why read-only MCP tools?** Recruiter demos should show credible AI integration without granting autonomous mutation rights. Operational writes remain explicit product workflows with authorization, validation and audit.
 **Why synthetic but production-shaped data?** The public demo can remain safely open while still exercising realistic state transitions, failure recovery and resettable scenarios.
