Bilko demo — reverse-engineering + feature list + live Playwright test (MC #102883) — 2026-06-03

Summary

MC #102883 reverse-engineered the Bilko demo product from existing code into a full spec chain, then validated the live demo with Playwright. Target: bilko-demo.alai.no (HR/EUR/PDV demo tenant). No deploy; no product code changed (docs + e2e spec only).

Pipeline delivered (durable in docs/reverse-engineering/)

  • Architecture — architecture-map.md (backend, salvaged from #102798) + frontend-ux-flows.md (17 UX flows, 39 Next.js routes mapped).
  • User stories — user-stories.md (97, sectioned, HR-demo-core flagged).
  • Requirements — requirements.md (65 functional + 30 non-functional, traceable to features/stories).
  • Feature list — feature-list.md (131 features, 115 HR-demo-core), each with a testable expectation + a real-vs-mock annotation.

Live testing (Playwright / webapp-testing)

  • Spec: apps/e2e/tests/phase-b-feature-coverage.spec.ts (54 tests, 16 domains), run against live bilko-demo.alai.no (login [email protected]).
  • Result: 54 passed / 0 failed. 39 screenshots. 0 real product bugs.
  • 8 intentional stubs confirmed behaving correctly (banking "u pripremi", VAT PDF/Excel export disabled, ePorezna disabled, email-send blocked, payables empty-state).
  • High-value confirmations: login→dashboard (real EUR data 18.420,75), invoice wizard (auto-number INV-2026-004, HR VAT 25%, BT-3 380 Račun), PDF export real, OIB label correct, settings org loaded, upsell modal renders.
  • 2 initial failures were test-selector bugs (not product) — fixed (placeholder*="Puno ime", getByRole textbox Pretraži račune), suite re-run fully green.

Verification

  • Independent pre-verifier (Company Mesh / Proveo): PASS — mesh-thr-7a45d8e0-c63a-4803-909a-8177f73b0630.
  • til-done: DONE — /tmp/til-done/102883-20260603T212200Z.json.

Deferred (follow-up MC #102884)

~28 features need a resettable demo tenant + 2nd account (viewer/accountant) to test safely: RBAC role-gating, destructive write flows (draft save/resume, OIB validation, travel-order/expense create+approve), multi-tenant isolation. These must NOT run against the customer-facing demo — deferred by design.
