_claim_due_events flipped rows to 'delivering' and committed before the HTTP call; if the process died between that commit and the outcome- recording transaction, the row stayed 'delivering' forever with no reclaim path -- a real gap, not previously documented as an accepted limitation. Give each claim a lease deadline (reusing next_attempt_at, since it's only otherwise meaningful for pending-status backoff scheduling) and sweep expired leases back to pending at the start of every dispatch cycle, before claiming new work. attempts is preserved so the count still reflects true history. Only leases past their deadline are touched, so a still-alive worker mid-delivery is never disturbed or double-processed.
MobilityOps
Connected operations for vehicle rental and service teams.
MobilityOps is a working proof of concept for a fictitious mobility company. It combines vehicle and booking operations, a controlled vehicle-return workflow, data-quality review, RAGcore-backed internal knowledge, n8n orchestration and read-only tools published through ITWorx MCP Hub.
The web application uses the premium responsive Control Rail interface: a compact
operations-first workspace with persisted readiness metrics, evidence-led exceptions,
review-before-commit return handling and mobile navigation designed down to 390 px. See
docs/design/design-directions.md and docs/design/implementation-validation.md for the
design decision and visual evidence.
All people, companies, vehicles, bookings and documents are synthetic. The workflows, validation, integrations, audit logging and access boundaries are intended to be real.
Scope
The PoC implements:
- operations dashboard;
- vehicle and booking views;
- one complete vehicle-return workflow;
- five deterministic data-quality checks;
- human review and customer merge;
- audit trail;
- RAGcore-backed knowledge assistant with citations;
- one n8n return-processing workflow;
- four read-only MCP tools through ITWorx MCP Hub;
- deterministic demo reset and five-minute showcase.
It is not an ERP, CRM, accounting package, public booking site, payment system or autonomous agent.
Integration status
- n8n: fully implemented and verified against a real n8n instance, including
degraded mode (n8n stopped mid-flow → return still commits, event stays
pendingwith backoff, self-heals once n8n returns) and the failed-delivery manual-retry path. - RAGcore: the demo
KnowledgeProvider(deterministic TF-IDF extractive retrieval over the local procedure documents) is what satisfies the knowledge-assistant acceptance criteria and is fully verified. ARAGcoreKnowledgeProviderHTTP adapter is implemented and unit-tested, including its unavailable-degradation path, but was never exercised against a live RAGcore instance in this environment. - ITWorx MCP Hub: the four read-only provider endpoints are implemented, tested, and
directly
curl-verified with correct auth enforcement and audit logging. No live Hub instance was reachable in this environment to verify an actual Hub round trip.
See artifacts/final-acceptance/summary.md for full verification evidence and exact
commands.

Quickstart
cp .env.example .env
make demo
This builds and starts the full stack (migrations run automatically) and loads the
deterministic demo dataset. See docs/17-runbook.md for the one-time n8n workflow setup
required for the automation demo, and the full operational runbook.
Endpoints:
- Web:
http://localhost:1228 - API health:
http://localhost:8128/health - n8n:
http://localhost:5678
All defaults are configurable via .env (see .env.example).
