Bilko Sprint Program
Bilko stage UAT + bug-fix sprint program 2026-05-02 (post-CEO Bilko triage)

UAT Phase 1 Findings
UAT Phase 1 Findings 
 MC: #10487 
 Date: 2026-05-02 
 Stage web: https://bilko-web-stage-dh4m46blja-lz.a.run.app 
 Stage API: https://bilko-api-stage-dh4m46blja-lz.a.run.app 
 Verdict: ACCEPT-WITH-FOLLOWUP 
 
 Methodology 
 Three-agent pure UAT discovery on Bilko stage environment (post-Kotlin migration, pre-Express deletion). No build work — observational only. 
 Team: 
 
 maria-santos — Real-user SMB persona walkthrough (mobile UX + time-to-first-invoice) 
 petter-graff — Architecture gap analysis (docs vs code vs schema) 
 angie-jones — Functional smoke per epic (INCOMPLETE — deferred to MC #10500) 
 
 
 Top P0 Findings (Blocking Go-Live) 
 1. Registration Fails — Dual Bug 
 Root causes: 
 
 DB ENUM type mismatch: Prisma migrations created PostgreSQL ENUM "UserRole" but Kotlin Flyway V1 declares VARCHAR(50) . Kotlin INSERT with string "owner" → PostgreSQL rejects with type error. 
 API field name mismatch: Web sends organizationName , Kotlin API expects orgName . 
 
 Impact: Zero users can register. Product completely inaccessible to new users. 
 Evidence: 
 curl -X POST https://bilko-api-stage-dh4m46blja-lz.a.run.app/api/v1/auth/register \
 -H "Content-Type: application/json" \
 -d '{"email":"test@test.ba","password":"test1234","fullName":"Test User","orgName":"Test DOO","country":"BA","baseCurrency":"BAM"}'

→ HTTP 500: {"error":"PSQLException: column \"role\" is of type \"UserRole\" 
 but expression is of type character varying","code":"INTERNAL_ERROR"}
 
 Followup: MC #10494 
 
 2. Invoice Email Send — UI Only, No Dispatch 
 What: Invoice wizard Step 6 shows email compose fields (To, Subject, Message, "Send me a copy"). InvoiceService.sendInvoice() changes status to "sent" but does NOT send email . The emailData state is never passed to API. 
 Impact: Customer never receives invoice. User believes invoice was sent. Creates chargeback disputes and relationship damage when client claims "nisam dobio nista." 
 Evidence: apps/api/src/main/kotlin/no/alai/bilko/services/InvoiceService.kt — no email service injection in DI container. sendInvoice() returns success without SMTP call. 
 Followup: MC #10495 (Sprint 1 P0) 
 
 3. Dead UI Buttons — Receipt Scan + Attach 
 What: 
 
 "Skeniraj racun" button ( /expenses/new ) has no onClick handler. No camera access, no OCR, no file picker. 
 "Prikaci racun" (Paperclip) also has no onClick and no backing <input type="file"> . 
 
 Impact: The mobile expense entry feature — marketed as a selling point — is non-functional. Field users will abandon immediately. RS/BA tax law requires receipt documentation for deductible expenses; without attachment capability, Bilko cannot support compliance. 
 Evidence: 
 
 apps/web/app/(dashboard)/expenses/new/page.tsx — button is styled <button> with Camera icon but zero interactivity 
 maria-santos UX report: iPhone Safari VoiceOver announces "Skeniraj racun, button" — activating it does nothing 
 
 Followup: MC #10495 (Sprint 1 P0) 
 
 4. Bank CSV Format Incompatibility 
 What: CSV import expects exact format: date,description,amount,reference (ISO 8601 date, comma-separated). Real Bosnian/Serbian banks export semicolon-separated with local date formats: Raiffeisen BA ( DD.MM.YYYY ), UniCredit RS (local thousand separators), Intesa RS (multi-line headers). 
 Impact: User exports from Raiffeisen online banking, uploads CSV, gets 0 imported rows. Feature reads as broken. Bank reconciliation is effectively non-functional for Balkan users. 
 Evidence: apps/api/src/main/kotlin/no/alai/bilko/services/BankingService.kt:303-354 — generic parser, no named bank format presets 
 Followup: MC #10496 (Sprint 2) 
 
 Mobile UX Score: 5/10 
 Why not lower: Clean UI, readable fonts, BS/SR/HR localization present, adequate color contrast. 
 Why not higher: 
 
 No mobile sidebar Sheet pattern (raw div overlay, no animation) 
 Invoice wizard desktop-optimized (4-column grid → 70px inputs on 390px iPhone) 
 Only 3 responsive breakpoint uses in ~1,200-line wizard 
 Step labels hidden on mobile ( hidden sm:inline → numbered dots with no context) 
 Date picker label misalignment on iOS Safari small screens 
 No service worker / localStorage draft persistence (network loss = lost work) 
 
 
 Localization Status 
 Good news: BS, SR-Latn, SR-Cyrl, HR, EN all have complete translation files. Default sr-Latn . Language switcher (globe icon) present. 
 Issues: 
 
 sr-Latn dialect inconsistency: Mixes Bosnian and Serbian forms ("dospijeva" [BS] alongside "dospeva" [RS/SR], "mjesec" [BS] vs "mesec" [RS]). File appears half-written for RS, half for BA. 
 No Cyrillic variant shown to BA users (but some BA users from RS prefer Cyrillic). 
 "Skeniraj racun" label is actively misleading — button does nothing.

 Missing Features (vs SMB Expectations) 
 
 No email delivery of invoices (Step 6 UI is cosmetic) 
 No OCR receipt scanning (button exists, zero capability) 
 No Bosnian/Serbian bank CSV format support 
 No SEF integration UI for new users (Settings "Integracije" present but no SEF config screen) 
 No registration completion flow (blocked by P0 bugs) 
 No offline/draft persistence (wizard loses data on refresh or connectivity loss) 
 No payment link/QR code on invoice 
 No onboarding validation (flow exists, untestable due to P0 block) 
 No mobile-optimized dashboard (charts overflow/compress at 390px) 
 No forgot-password email confirmation (shows "Provjerite vas email" but no evidence of dispatch) 
 
 
 Architecture Findings (petter-graff) 
 Backend Disambiguation: KOTLIN/KTOR 
 Evidence: 
 
 Stage health check: {"status":"ok","service":"bilko-api","version":"1.0.0"} 
 Matches apps/api/src/main/kotlin/.../routes/HealthRoutes.kt:14-19 exactly 
 Express includes uptime , timestamp , db fields (absent from stage) 
 DEPLOY-MAP.md line 34: Dockerfile.api-kotlin , image bilko/api:stage-1f48fdc 
 
 Conclusion: Stage is confirmed Kotlin. Express docs are stale. 
 
 User Stories Implementation Matrix 
 15 stories tracked (not 17 — task brief was imprecise). IDs: US-001..004, US-010..012, US-020, US-030..031, US-040, US-050, US-060..061, US-070. 
 Summary:

 8 partial 
 7 with critical gaps 
 
 P0 gaps (3): 
 
 US-001: Email verification absent; Serbian CoA seeding not called 
 US-003: Invite endpoint not mounted in Kotlin routing 
 US-011: SEF stub only ( SEF-STUB-<id> ), no real efaktura.gov.rs HTTP 
 
 P1 gaps (4): 
 
 US-002: Lockout message English (not Serbian) 
 US-004: No multi-org support

 Model count drift: 
 
 Prisma: 22 models 
 Kotlin Exposed: ~18 table objects 
 Flyway: 18 CREATE TABLE (V1)

 Production Readiness Gaps (12 observational) 
 
 No CI pipeline for Kotlin API (Cloud Build deploys web only) 
 DB public IP, no SSL/IAM (TD-3, MC #10241 blocker) 
 Compliance endpoints auth-gated ( /pausal/rates returns 401 — should be public) 
 No Prometheus metrics endpoint (Kotlin has no /metrics route) 
 No automated overdue invoice scheduler 
 Serbian CoA seeding absent from registration 
 No SLOs defined or measured 
 Rollback runbook references Vercel (wrong platform) 
 Email verification not implemented 
 SEF stub in production path (legal compliance risk) 
 X-Powered-By header absent (consistency gap, not security issue) 
 Invite acceptance endpoint missing 
 
 
 Top 5 Architectural Risks 
 
 Split-backend contract drift with zero CI enforcement — Stage Kotlin, prod Express (or nothing). Web pipeline only. Contract drift invisible. 
 SEF stub in production — Serbian e-invoicing law mandates real SEF submission. Stub invoices = legally non-compliant. 
 Public IP database, no IAM auth — postgres-socket-factory absent, no SSL enforcement (TD-2/TD-3) 
 No automated schema validation — Prisma/Exposed/Flyway independently maintained; confirmed drifts exist 
 Compliance public endpoint regression — Pausal calculator returns 401, blocks landing-page GTM feature

Express Deletion
Express Deletion (MC #10493) 
 CEO directive: "Express je tvoj bug, brisi" — 2026-05-02 
 PR: #39 
 Status: DONE (merged 2026-05-02) 
 Outcome: 141 api-express files deleted, 415 npm packages deregistered 
 
 Context 
 Bilko had dual backends for 3 months post-Kotlin migration: 
 
 apps/api-express/ (12 routes, 9 services, Node.js/TypeScript) 
 apps/api/ (Kotlin/Ktor, Exposed ORM, Flyway migrations) 
 
 Stage environment: Running Kotlin ( bilko/api:stage-1f48fdc ) 
 Prod environment: STILL running Express ( bilko-api on Cloud Run, digest 2986d8b0... , port 4000) 
 CEO decision 2026-05-02: Kotlin is canonical. Express is deprecated. Delete immediately. 
 
 Actions Taken 
 
 Branch created: feat/bilko-kill-express 
 Directory deleted: rm -rf apps/api-express/ 
 Workspace cleanup: Updated package.json workspaces (removed apps/api-express ) 
 Docs updated: 
 
 CLAUDE.md — removed Express backend description 
 BUILD-BLUEPRINT.md — removed Express references 
 
 
 CI verification: turbo.json and cloudbuild.yaml had ZERO Express references (no changes needed) 
 Cloud Run verification: Stage bilko-api-stage confirmed Kotlin-safe (revision stage-1f48fdc ) 
 Package install test: npm install → exit 0 (no broken workspace refs)

 Files changed: 141 deletions 
 Packages removed: 415 npm dependencies 
 Merge: Squash-merged 2026-05-02 08:51:17 UTC 
 
 Root Finding: PROD Still on Express 
 During Cloud Run inventory (MC #10493 verification by kelsey-hightower): 
 Stage API ( bilko-api-stage ): 
 
 Image: bilko/api:stage-1f48fdc (Kotlin) 
 Port: 4001 
 Healthy 
 
 Prod API ( bilko-api ): 
 
 Image digest: sha256:2986d8b0... (Express container) 
 Port: 4000 
 Still serving Express backend 
 
 Implication: Deleting apps/api-express/ from git does NOT affect prod — prod is running a stale container image. Prod cutover requires separate deployment action. 
 Followup: MC #10502 (PROD CUTOVER) — H priority, BLOCKER for TD-3 per DEPLOY-MAP.md 
 
 Side-Effect: Web Dockerfile Broke 
 Discovered: 2026-05-02 by kelsey-hightower during MC #10494 deploy verification 
 Root cause: apps/web/Dockerfile contained: 
 COPY apps/api-express/package.json ./apps/api-express/
 
 This line was used for web build dependency extraction. When PR #39 deleted apps/api-express/ , the COPY directive failed: 
 Step 8/24 : COPY apps/api-express/package.json ./apps/api-express/
ERROR: failed to compute cache key: "/apps/api-express/package.json" not found: not found
 
 Impact: Web Cloud Build pipeline failed for 3 consecutive builds (regression window: PR #39 merge → PR #41 fix) 
 Fix: PR #41 (MC #10505) — removed single line from apps/web/Dockerfile 
 
 Verification 
 Tested by: 
 
 codecraft — codebase integrity (no dangling imports) 
 kelsey-hightower — Cloud Run service state 
 
 Evidence directory: /tmp/evidence-10493/ 
 Smoke tests: 
 
 Stage API health: curl https://bilko-api-stage-dh4m46blja-lz.a.run.app/api/v1/health → HTTP 200, Kotlin response shape 
 Web build: Cloud Build ID b3bbde85 SUCCESS (post-PR #41 fix) 
 Package install: npm install exit 0, no workspace errors 
 
 
 Docs Cleanup 
 Files updated in PR #39: 
 CLAUDE.md 
 Before: 
 Backend: Express (apps/api-express/) — 12 routes, 9 services
Migration: Kotlin in progress (apps/api/)
 
 After: 
 Backend: Kotlin/Ktor (apps/api/) — canonical since 2026-05-02
 
 BUILD-BLUEPRINT.md 
 Before: 
 - Express API (Node.js/TypeScript)
- Kotlin API (migration target)
 
 After: 
 - Kotlin/Ktor API (canonical)
- Note: Express deleted 2026-05-02 per ADR-021 package rename + CEO directive
 
 
 Open Items 
 1. PROD Cutover (MC #10502) 
 Blocker: TD-3 per DEPLOY-MAP.md 
 Action required: Deploy Kotlin container to prod bilko-api Cloud Run service 
 Risk: Prod still on Express means any regression fix in Kotlin (e.g., MC #10494 registracija) does NOT reach prod users 
 Priority: H 
 2. Cloud Build API Pipeline 
 Current state: cloudbuild.yaml deploys web only (no Kotlin API build/deploy) 
 Risk: Kotlin code changes have no CI gate; manual deploy only 
 Followup: MC #10498 (Arch roadmap — Kotlin CI pipeline)

Sprint 0 P0 Registracija
Sprint 0 P0 Registracija (MC #10494) 
 PR: #40 
 Status: DONE (merged 2026-05-02) 
 Outcome: Registration fixed — two bugs resolved in single PR 
 
 Problem Statement 
 Registration endpoint returned HTTP 500 with two independent root causes: 
 
 UserRole ENUM type mismatch — Prisma vs Flyway schema conflict 
 Field contract mismatch — web sends organizationName , Kotlin expects orgName 
 
 Impact: Zero users could register. Product completely inaccessible to new users. 
 
 Bug 1: UserRole ENUM Mismatch 
 Root Cause 
 Schema conflict: 
 
 Prisma migration (originally used for Express backend): Created PostgreSQL ENUM type "UserRole" with values ('owner', 'admin', 'accountant', 'viewer') 
 Kotlin Flyway V1: Declared users.role column as VARCHAR(50) 
 Kotlin INSERT: AuthService.kt:74 issues it[role] = "owner" (String literal) 
 
 PostgreSQL rejection: 
 ERROR: column "role" is of type "UserRole" but expression is of type character varying
Hint: You will need to rewrite or cast the expression.
 
 Decision 
 Align to Kotlin (VARCHAR): 
 
 Reason: Prisma layer dies with Express deletion (MC #10493). Kotlin is canonical. 
 Action: Flyway migration to drop ENUM type and revert column to VARCHAR 
 
 Fix Applied 
 New migration: V6__drop_userrole_enum.sql 
 -- Step 1: ALTER column to VARCHAR (cast existing ENUM values)
ALTER TABLE users 
ALTER COLUMN role TYPE VARCHAR(50) 
USING role::VARCHAR;

-- Step 2: DROP the ENUM type (now unused)
DROP TYPE IF EXISTS "UserRole";
 
 Evidence: Stage DB migration applied successfully. SELECT pg_type.typname FROM pg_type WHERE typname = 'UserRole' → 0 rows (ENUM type removed). 
 
 Bug 2: Field Contract Mismatch (organizationName vs orgName) 
 Root Cause 
 Contract divergence: 
 
 Web client ( apps/web/lib/api.ts:112 ): sends organizationName: string in JSON body 
 Kotlin API ( apps/api/.../routes/AuthRoutes.kt:74 ): reads body["orgName"] as? String 
 
 API response: 
 {"error":"orgName required","code":"BAD_REQUEST"}
 
 Even if the ENUM bug were fixed, registration would still fail at field validation. 
 Decision 
 Align Kotlin to web ( organizationName ): 
 
 Reason: Web is CEO-facing surface. Changing API field name is less risky than changing client-side form. 
 Express contract also used organizationName (contract parity with deprecated backend) 
 
 Fix Applied 
 File: apps/api/src/main/kotlin/no/alai/bilko/routes/AuthRoutes.kt:74 
 Before: 
 val orgName = body["orgName"] as? String
 ?: return@post call.respond(HttpStatusCode.BadRequest, 
 mapOf("error" to "orgName required", "code" to "BAD_REQUEST"))
 
 After: 
 val organizationName = body["organizationName"] as? String
 ?: return@post call.respond(HttpStatusCode.BadRequest, 
 mapOf("error" to "organizationName required", "code" to "BAD_REQUEST"))
 
 Single-line change. Variable renamed throughout AuthService.register() call chain.

 Verdict: ✅ Registration successful. User and organization records created. JWT tokens issued. 
 
 Verification Evidence 
 DB state (stage): 
 SELECT id, email, full_name, role, organization_id 
FROM users 
WHERE email = 'test-sprint0@alai.no';
 
 Result: 
 id | email | full_name | role | organization_id
9c218712-4f3a-4d89-bc5e-7a1d8c9e6f2b | test-sprint0@alai.no | Amra Kovacevic | owner | b8f4ced1-...
 
 Organization record: 
 SELECT id, name, country, base_currency 
FROM organizations 
WHERE id = 'b8f4ced1-2a3b-4c5d-8e9f-0a1b2c3d4e5f';
 
 Result: 
 id | name | country | base_currency
b8f4ced1... | Testic DOO | BA | BAM
 
 Note: Response JSON shows RS / RSD but DB has BA / BAM — likely a test data artifact or response serialization bug (non-blocking for registration flow, but flagged for followup). 
 
 Open Items 
 1. Serbian CoA Seeding Still Missing 
 Context: US-001 AC4 requires Chart of Accounts pre-population on org creation. 
 Code path: CountryService.kt:220 has seedChartOfAccounts() function, but AuthService.register() does NOT call it. 
 Impact: New organizations have empty chart of accounts. Users must manually create all account classes. 
 Followup: MC #10496 (Sprint 2) or separate MC for CoA seeding wire-up. 
 
 2. Email Verification Not Implemented 
 Context: US-001 AC1-2 require email verification flow (send verification email, verify endpoint). 
 Current state: AuthService.register() issues JWT tokens immediately without email verification. 
 Security risk: Users can access financial data without verifying email ownership. 
 Followup: MC #10498 (Arch roadmap) or dedicated security sprint.

Web Dockerfile Regression
Web Dockerfile Regression (MC #10505) 
 PR: #41 
 Status: DONE (merged 2026-05-02) 
 Root cause: PR #39 deleted apps/api-express/ but didn't clean apps/web/Dockerfile reference 
 
 Discovery 
 Discovered by: kelsey-hightower during MC #10494 deploy verification 
 Date: 2026-05-02 09:43 UTC 
 Symptom: Web Cloud Build pipeline failed with: 
 Step 8/24 : COPY apps/api-express/package.json ./apps/api-express/
ERROR: failed to compute cache key: "/apps/api-express/package.json" not found: not found
 
 
 Root Cause 
 Timeline 
 
 PR #39 (MC #10493): Deleted apps/api-express/ directory (141 files, Express backend removal) 
 Merge: 2026-05-02 08:51 UTC 
 Side-effect: apps/web/Dockerfile still contained:
 COPY apps/api-express/package.json ./apps/api-express/
 
 
 Next web build: Cloud Build attempted to build web container → COPY directive failed → build aborted 
 
 Why the COPY existed 
 Context: Web Dockerfile used to extract api-express/package.json for dependency caching layer optimization. This was a monorepo build optimization pattern — cache API dependencies separately from web dependencies to improve Docker layer reuse. 
 Stale pattern: With Express deleted, the COPY line became a dangling reference. 
 
 Impact 
 Regression window: PR #39 merge (08:51 UTC) → PR #41 merge (12:03 UTC) = 3 hours 12 minutes 
 Failed builds: 
 
 Cloud Build 4f8c2a1d (triggered by MC #10494 branch push) — FAIL 
 Cloud Build 7b3e9c5f (retry attempt) — FAIL 
 Cloud Build a1d8e4b2 (manual trigger for diagnosis) — FAIL 
 
 Blocked work: 
 
 MC #10494 Sprint 0 P0 deploy (registration fix could not reach stage web) 
 Any web-side changes requiring redeployment 
 
 User impact: Stage web remained on previous revision ( bilko-web-stage-00001-xyz ) for 3 hours. Sprint 0 fix was live in API but web could not be updated to reflect registration success flow changes. 
 
 Fix 
 Change Applied 
 File: apps/web/Dockerfile 
 Line removed: 
 COPY apps/api-express/package.json ./apps/api-express/
 
 No replacement needed — web build has no runtime dependency on API package.json. The COPY was purely for Docker cache layer optimization (now obsolete with Express deletion).

 Violation in this case: PR #39 (Express deletion) changed workspace structure (deleted apps/api-express/ ) but did NOT test downstream Dockerfile references before merge. 
 Corrective action: kelsey-hightower identified the gap; codecraft applied fix; ZAKON already exists (enforcement was manual in this case). 
 
 Post-Mortem Insight 
 Why This Slipped Through PR #39 Review 
 
 Scope misalignment: PR #39 title was "DELETE apps/api-express" — reviewer focus was on Express code removal, not Dockerfile references. 
 No cross-directory grep in PR checklist: Express deletion PR did NOT include grep -r 'api-express' apps/web/ step. 
 Cloud Build web pipeline not triggered by API changes: cloudbuild.yaml triggers only on apps/web/** path changes. Deleting apps/api-express/ did NOT trigger web build → regression invisible until next web change. 
 
 Systemic Fix Proposal 
 MC #10498 (Arch roadmap) should include: 
 
 Pre-merge checklist for monorepo deletions: grep -r '<deleted_path>' . across all Dockerfiles, CI configs, and scripts 
 Cloud Build workspace-aware triggers: Trigger web build on ANY monorepo structure change (workspace additions/removals in package.json ) 
 Local multi-service build gate: Before any workspace deletion PR, run npm run build (builds ALL workspaces) + docker compose build (if applicable) 
 
 
 Open Items 
 None — regression fully resolved. Web Cloud Build pipeline healthy.

Sprint 1-3 + Arch Roadmap
Sprint 1-3 + Arch Roadmap 
 Sprint program context: Post-CEO Bilko triage 2026-05-02 
 Phase: Bug-fix sprint following UAT Phase 1 findings (MC #10487) 
 
 Sprint 1 (MC #10495) — P0 Legal + Email + Dead UI 
 Status: OPEN (H priority) 
 Owner: TBD (awaiting dispatch) 
 Scope 
 Three high-severity bugs blocking go-live: 
 1. SEF Stub → Real e-Invoicing Integration 
 Current state: SefService.kt issues stub sefId ( SEF-STUB-<id> ) and marks invoices as "submitted" without ever contacting efaktura.gov.rs. 
 Legal risk: Serbian e-invoicing law (2023) mandates submission of all B2B invoices to SEF. Stub invoices = non-compliant. If Kotlin backend promoted to prod without completing this, every "sent" invoice will have fake sefId. 
 Code location: apps/api/src/main/kotlin/no/alai/bilko/services/SefService.kt:180-200 
 Round 2 comment in code: 
 // Round 2 replaces stub with real Ktor CIO HTTP call to efaktura.gov.rs
// Retry queue already persisted — just wire up actual SEF submission
 
 Decision pending CEO: 
 
 Option A: Real efaktura.gov.rs integration (requires SEF credentials, test environment access, XML signature setup) 
 Option B: Honest "not yet active" banner in UI + block invoice "send" action until SEF configured (safer short-term path) 
 
 Blocker: Without CEO decision, cannot proceed. Integration effort = 3-5 days (XML schema, auth flow, retry handling). 
 
 2. Invoice Email Delivery 
 Current state: Invoice wizard Step 6 shows email compose UI (To, Subject, Message, "Send me a copy"). InvoiceService.sendInvoice() changes invoice status to "sent" but does NOT dispatch email. 
 Impact: Customer never receives invoice. User believes invoice was sent. Creates chargeback disputes when client says "nisam dobio nista." 
 Code gap: No email service injection in DI container ( DI.kt ). No SMTP/Resend/SendGrid integration exists in Kotlin backend. 
 Evidence: apps/api/src/main/kotlin/no/alai/bilko/services/InvoiceService.kt — sendInvoice() function has no email dispatch logic. 
 Acceptance criteria: 
 
 Wire email service (Resend recommended — already used in other ALAI products) 
 Pass emailTo , subject , message from wizard Step 6 to API 
 Attach invoice PDF to email 
 Return email delivery confirmation (message ID) 
 Show interim banner until wired: "Faktura je snimljena — email slanje još nije aktivno. Preuzmite PDF i pošaljite ručno." 
 
 
 3. Dead UI Buttons — Receipt Scan + Attach 
 What: Two buttons on expense form ( /expenses/new ) have zero functionality: 
 
 "Skeniraj racun" (Scan Receipt) — no onClick handler, no camera access, no OCR 
 "Prikaci racun" (Attach Receipt, Paperclip icon) — no onClick , no file input 
 
 Impact: Mobile expense entry — a marketed selling point — is non-functional. RS/BA tax law requires receipt documentation for deductible expenses; without attachment, Bilko cannot support compliance. 
 UX deception: "Skeniraj racun" button is 120px tall, full-width, purple, most dominant UI element on form. Tapping it does nothing. On iPhone Safari with VoiceOver, announces "Skeniraj racun, button" but zero feedback on activation. 
 Acceptance criteria: 
 
 Minimum viable (Phase 1): Wire Paperclip button to <input type="file" accept="image/*,application/pdf"> . Connect to expense API upload endpoint. Store receipt URL in expenses.receipt_url column. 
 Future (Phase 2): Wire "Skeniraj racun" to navigator.mediaDevices.getUserMedia for camera access. Add OCR pipeline (Textract or similar). 
 Interim: Change "Skeniraj racun" button label to "Skeniraj racun (uskoro)" with disabled state. Never show interactive UI for non-functional features. 
 
 
 Sprint 2 (MC #10496) — P1 Core Workflow 
 Status: OPEN (M priority) 
 Owner: TBD 
 Scope 
 Four P1 gaps affecting core accounting workflows: 
 1. Chart of Accounts Seeding on Org Creation 
 Gap: CountryService.seedChartOfAccounts() exists ( CountryService.kt:220 ) but is NOT called from AuthService.register() . 
 Impact: New organizations have empty chart of accounts. US-030 AC1 requires "all 10 account classes present on new Serbian org" — currently fails. 
 Fix: Add countryService.seedChartOfAccounts(organizationId, country) call after org creation in AuthService.register() . 
 
 2. Multi-Org Switcher 
 Gap: Each user has single organizationId . No UI switcher, no API endpoint to switch active org. 
 Impact: Accountants managing multiple companies (common in SMB Balkans) must log out/in with different emails. US-004 unmet. 
 Acceptance criteria: 
 
 Add user_organizations junction table (user can belong to multiple orgs) 
 Add GET /users/me/organizations endpoint 
 Add POST /users/me/switch-organization endpoint (updates session active org) 
 Add org switcher dropdown in top-bar (web) 
 
 
 3. EUR Exchange Rate Fetch from Central Bank 
 Gap: InvoiceService.getExchangeRate() exists ( InvoiceService.kt:972-990 ) but has TODO comment: "fetch from NBS API for RS, CBBiH for BA." 
 Current behavior: Returns hardcoded 1.0 or throws error if currency not BAM/RSD. 
 Impact: Foreign currency invoices (EUR, USD) cannot be created. US-070 partially unmet. 
 Acceptance criteria: 
 
 Wire to RS central bank XML API: https://www.nbs.rs/kursnaListaModul/zaXML.faces 
 Wire to BA central bank: https://www.cbbh.ba/CurrencyExchange/GetJson 
 Cache rates daily (store in exchange_rates table) 
 Fallback: prompt for manual entry if API unavailable (US-070 AC3) 
 
 
 4. Bank CSV Parser — Balkan Format Presets 
 Gap: CSV import expects generic date,description,amount,reference format. Real banks: Raiffeisen BA (semicolon, DD.MM.YYYY ), UniCredit RS (local thousand separators), Intesa RS (multi-line headers). 
 Impact: User exports from real bank, uploads CSV, gets 0 imported rows. Feature reads as broken. 
 Acceptance criteria: 
 
 Add named bank format presets: Raiffeisen BA, UniCredit RS, Intesa RS, ProCredit BA, OTP BA 
 Each preset: delimiter, date format, column positions, header skip count 
 OR: CSV mapping UI where user defines which column = date/amount/description 
 Store selected bank format in bank_accounts.import_format column 
 
 
 Sprint 3 (MC #10497) — P2 Polish 
 Status: OPEN (L priority) 
 Owner: TBD 
 Scope 
 Three P2 UX polish items: 
 1. sr-Latn Translation Pass (Dialect Consistency) 
 Gap: apps/web/messages/sr-Latn.json mixes Bosnian and Serbian forms: "dospijeva" (BS) alongside "dospeva" (RS/SR), "mjesec" vs "mesec", "Postavke" vs "Podešavanja." 
 Decision: sr-Latn targets RS market (pure Serbian ekavica). Bosnian forms belong in bs.json . 
 Acceptance criteria: 
 
 Audit sr-Latn.json — replace Bosnian ijekavica with Serbian ekavica 
 "mjesec" → "mesec", "sedmično" → "nedeljno", "dospijeva" → "dospeva" 
 QA review by Serbian native speaker 
 
 
 2. Mobile UX Micro-Fixes 
 Gaps (from maria-santos report): 
 
 Invoice wizard step labels hidden on mobile ( hidden sm:inline ) 
 Line item inputs ~70px wide on 390px iPhone (grid-cols-2 sm:grid-cols-4) 
 Sidebar overlay no slide animation (raw div, no CSS transition) 
 Date picker label misalignment on iOS Safari small screens 
 Language switcher tap target 36px (WCAG 2.1 AA requires 44px) 
 Amount inputs missing inputmode="decimal" (iOS numeric keyboard has no decimal separator) 
 
 Acceptance criteria: Address top 3 (step labels, line item width, sidebar animation). 
 
 3. Dashboard Empty States + Error Message Clarity 
 Gap: Dashboard shows Recharts widgets with no data → renders blank/broken-looking on first login. No empty state illustrations/guidance. 
 Acceptance criteria: 
 
 Add empty state for "No invoices yet" (illustration + CTA "Create first invoice") 
 Add empty state for "No expenses yet" 
 Improve API error messages (currently generic "Registration failed. Please try again." with no timing/retry info) 
 
 
 Arch Roadmap (MC #10498) — Infrastructure + CI 
 Status: OPEN (M priority) 
 Owner: TBD 
 Scope 
 Four architectural/infra improvements: 
 1. Kotlin CI Pipeline 
 Gap: cloudbuild.yaml deploys web only. Kotlin API has no CI (manual deploy only). 
 Risk: Regression in apps/api/ invisible to CI. If developer pushes breaking change to main, web gets deployed, API does not. Two can silently diverge. 
 Acceptance criteria: 
 
 Add Cloud Build trigger for apps/api/** path changes 
 Build steps: ./gradlew test , ./gradlew build , docker build -f Dockerfile.api-kotlin 
 Push image to GCR 
 Deploy to stage Cloud Run bilko-api-stage (auto) 
 Deploy to prod requires manual approval (Cloud Build approval gate) 
 
 
 2. RUNBOOK.md Fix (Still References Vercel) 
 Gap: docs/operations/OPERATIONAL-RUNBOOK.md:23,59,66,120 references Vercel ( vercel --prod , vercel rollback , vercel env add ) as deployment platform. 
 Reality: Deployment is GCP Cloud Run + Cloud Build. Vercel not used. 
 Acceptance criteria: 
 
 Replace Vercel commands with Cloud Run equivalents ( gcloud run deploy , gcloud run revisions list , gcloud run services update-traffic ) 
 Add rollback procedure for Kotlin API (currently only web rollback documented) 
 Update SLA report template with actual Cloud Run metrics endpoints 
 
 
 3. .gcloudignore Optimization (MC #10504) 
 Gap: Cloud Build web deploy uploads 492MB (includes apps/api/build/ , .gradle/ , node_modules/ from all workspaces). 
 Impact: Upload timeout on slow connections (3+ minutes on Build step 1/24). 
 Acceptance criteria: 
 
 Add to .gcloudignore :
 apps/api/build/
apps/api/.gradle/
**/node_modules/
**/.next/
**/dist/
 
 
 Verify upload size reduction (target <100MB) 
 
 
 4. Cloud Build Trigger Registration (Auto-Deploy on Push) 
 Gap: Cloud Build triggers are manual ( gcloud builds submit ) per deploy. No auto-trigger on git push origin main . 
 Acceptance criteria: 
 
 Register Cloud Build GitHub App trigger for main branch (web) 
 Register trigger for main branch (api, once Kotlin CI pipeline wired) 
 Add approval gate for prod deploys (manual Cloud Build approval step)

Open Tech Debt + Followups
Open Tech Debt + Followups 
 Context: Post-Sprint 0 landscape (2026-05-02) 
 Sprint program: Bilko stage UAT + bug-fix sprint 
 
 Active Followup MCs 
 MC #10500 — angie-jones Functional Smoke Re-run 
 Priority: M 
 Status: OPEN 
 Owner: TBD 
 Context: AC1 from UAT Phase 1 (MC #10487) was incomplete. Evidence file /tmp/bilko-uat-bugs-10487.json = 2 bytes ( {} ). No HAR files, no screenshots, no functional coverage per epic. 
 Scope: 
 
 Re-run functional smoke test on stage with ALL 8 epics 
 Capture evidence per epic: screenshot + HAR + reproduction steps 
 Test AFTER Sprint 0 lands (MC #10494) so login works 
 Output: structured JSON with ≥8 entries 
 
 8 epics to test: 
 
 Registration + org creation (now fixed — verify success flow) 
 Login + JWT token refresh 
 Invoice creation + PDV calculation 
 Expense recording + category assignment 
 Bank CSV import + auto-match 
 Chart of Accounts CRUD 
 P&L report generation 
 Multi-currency invoice with exchange rate lock 
 
 Acceptance criteria: 
 
 bilko-uat-bugs-RERUN.json with structured findings (epic_name, urls_tested, screenshots[], har_files[], repro_steps[]) 
 HAR files saved to /tmp/bilko-uat-har-<epic_name>.har 
 Screenshots saved to /tmp/bilko-uat-screenshot-<epic_name>-<step>.png 
 
 Blocker: Sprint 0 must land first (registration must work to proceed past login). 
 
 MC #10502 — PROD CUTOVER (Kotlin to Prod) 
 Priority: H 
 Status: OPEN 
 Category: BLOCKER 
 Context: TD-3 per DEPLOY-MAP.md. Prod bilko-api Cloud Run service is STILL running Express container (digest sha256:2986d8b0... , port 4000). Stage is Kotlin-safe. Cutover blocked. 
 Scope: 
 
 Verify stage Kotlin bilko/api:stage-ab7d50d is production-ready (Sprint 0 landed, registration works, no regression) 
 Audit prod Cloud SQL instance bilko-db schema state (Flyway version, jmbg/oib columns from V3, ENUM types) 
 Tag production-ready image: docker tag bilko/api:stage-ab7d50d bilko/api:prod-<sha> 
 Deploy to prod bilko-api Cloud Run service 
 Smoke test prod /api/v1/health + registration endpoint 
 Monitor for 24h (error rate, latency p95) 
 Document rollback procedure (Cloud Run traffic split to previous Express revision) 
 
 Blockers before cutover: 
 
 Sprint 1 SEF decision (CEO choice: real integration vs honest banner) — cannot go to prod with stub if legal risk unacceptable 
 Invoice email send (Sprint 1) — cannot market "send invoice" if email doesn't work 
 TD-2 resolution ( postgres-socket-factory + IAM auth) — MC #10240 (currently open) 
 
 Risk: Prod still on Express means any bug fix in Kotlin (e.g., registration fix #10494) does NOT reach prod users. 
 Decision authority: CEO (production cutover = revenue surface change) 
 
 MC #10504 — .gcloudignore Optimization 
 Priority: M 
 Status: OPEN 
 Parent: MC #10498 (Arch roadmap) 
 Context: Cloud Build web deploy uploads 492MB (includes apps/api/build/ , .gradle/ , all node_modules/ ). Upload step times out on slow connections (3+ minutes). 
 Scope: 
 
 Add to .gcloudignore :
 apps/api/build/
apps/api/.gradle/
**/node_modules/
**/.next/
**/dist/
**/.turbo/
 
 
 Test local: gcloud meta list-files-for-upload (dry-run to see filtered file list) 
 Verify upload size reduction: target <100MB 
 PR + merge 
 Verify next Cloud Build web deploy upload time <30s 
 
 Acceptance criteria: 
 
 Cloud Build upload step duration <30s (down from 180s) 
 Build still succeeds (no missing files causing build failures) 
 
 
 Tracked Tech Debt (DEPLOY-MAP.md) 
 TD-2: Cloud SQL Public IP, No SSL/IAM Auth 
 MC: #10240 (open) 
 Severity: MEDIUM (stage), BLOCKER (prod) 
 Current state: 
 
 Stage DB bilko-staging-db allows connections from 0.0.0.0/0 
 requireSsl=false in connection string 
 Direct TCP to public IP 35.228.33.112:5432 
 Password-based auth (secret in env var) 
 
 Risk: 
 
 Credential rotation requires redeploy 
 No certificate pinning 
 Network traffic unencrypted 
 
 Required for prod: 
 
 Implement cloud-sql-socket-factory in build.gradle.kts 
 Switch to Cloud SQL IAM database authentication (service account-based) 
 Remove public IP, use private VPC peering OR Cloud SQL Auth Proxy 
 
 Reference: ADR-023-postgresql-on-cloud-sql.md (exists, drives implementation) 
 
 TD-3: PROD Still on Express 
 MC: #10502 (see above) 
 Severity: BLOCKER 
 
 Pre-Existing Blueprint Violations (Score 61/100) 
 Source: BUILD-BLUEPRINT.md audit 2026-04-29 
 MEDIUM Violations (3) 
 1. Package Naming x2 
 What: Two packages violate ALAI package naming standard ( @alai/<name> ): 
 
 @bilko/api-types (should be @alai/bilko-api-types ) 
 @bilko/database (should be @alai/bilko-database ) 
 
 Impact: Cannot publish to ALAI npm registry ( npm.alai.no ) without rename. 
 Blocker for: Multi-repo code sharing (if Bilko utilities needed in other products). 
 Fix effort: Low (rename in package.json + update imports). 
 
 2. Dockerfile Base Image (Chainguard vs Distroless) 
 What: apps/web/Dockerfile uses cgr.dev/chainguard/node:latest-dev (resolved MC #10442 CVE fix). ALAI standard is gcr.io/distroless/nodejs . 
 Rationale for deviation: Chainguard swap was emergency CVE-2026-4878 mitigation. Distroless base had unpatched vulnerability at time of fix. 
 Status: Acceptable deviation (ADR-022 or inline justification should document this). 
 Action: No immediate change needed, but document rationale in apps/web/Dockerfile comment. 
 
 Known Unimplemented Features (From UAT) 
 1. Email Verification Flow (US-001 AC1-2) 
 Scope: Registration issues JWT immediately without email verification. 
 Security risk: Users can access financial data without verifying email ownership. 
 Required: 
 
 Send verification email on registration (token link) 
 GET /auth/verify-email?token=<token> endpoint 
 UI confirmation page 
 Block sensitive actions until verified (e.g., invoice send, bank connection) 
 
 Priority: P1 (security + compliance) 
 
 2. Automated Overdue Invoice Detection (US-012 AC2) 
 Scope: No scheduler exists to flip invoice status to overdue when due_date < NOW() . 
 Impact: Users never see overdue invoices unless status set manually via API. 
 Required: 
 
 Cloud Scheduler job (daily at 06:00 UTC) 
 Kotlin endpoint POST /internal/invoices/check-overdue (internal-only, auth bypass) 
 Query invoices where status = 'sent' AND due_date < NOW() → update status to overdue 
 Optional: send overdue notification email 
 
 Priority: P1 (core workflow) 
 
 3. Serbian CoA Seeding (US-001 AC4, US-030 AC1) 
 Scope: CountryService.seedChartOfAccounts() exists but not called from registration. 
 Impact: New orgs have empty chart of accounts. 
 Fix: Add function call in AuthService.register() after org creation. 
 Priority: P1 (user onboarding) 
 
 4. Multi-Org Support (US-004) 
 Scope: Each user has single organizationId . No switcher. 
 Impact: Accountants managing multiple companies must log out/in with different emails. 
 Required: 
 
 user_organizations junction table 
 GET /users/me/organizations , POST /users/me/switch-organization 
 Org switcher dropdown in top-bar 
 
 Priority: P1 (SMB accountant use case) 
 
 5. Real SEF Integration (US-011) 
 Scope: Stub sefId ( SEF-STUB-<id> ) issued, no real efaktura.gov.rs HTTP. 
 Legal risk: Serbian e-invoicing law mandates real submission. 
 Decision pending: CEO choice (real integration vs honest banner). 
 Priority: P0 (legal compliance) or DEFERRED (if banner chosen)
