Task ID: refactor-1 Agent: general-purpose Task: Fix all TypeScript compilation errors

Work Log:

• src/app/api/aos/webhooks/route.ts: Extracted the PATCH handler (which expected a { id } param but lived at the top-level route) into a new dynamic route file src/app/api/aos/webhooks/[id]/route.ts. Removed PATCH from the top-level route.ts. This also resolved the cascading .next/dev/types/validator.ts RouteHandlerConfig error.
• src/app/api/aos/kb/route.ts: Replaced the broken inline where type annotation with Prisma.ArticleWhereInput (imported Prisma from @prisma/client). The previous type declared OR as a single object, but the code assigns an array; the Prisma-generated type is the source of truth and accepts the OR array of filter objects including excerpt.
• src/app/api/aos/setup/test-mail/route.ts (line 57): Changed banner: banner || null to banner: banner || undefined so the value matches the banner?: string property on MailTestResult (optional string, not string | null).
• src/components/aos/mobile-bottom-nav.tsx: Widened the items array type from { id: ViewId | 'search' | 'menu'; ... } to { id: string; ... } so 'notifications' is allowed. Updated handleClick to take id: string (still casts to ViewId for the real view setter). Updated the active computation to cast the empty-string sentinel ('' as ViewId) so the equality check type-checks; behavior is unchanged (search/menu are never "active", notifications maps to 'calendar').
• src/components/aos/views/crm.tsx (line 268): Changed p.companyId && onSelectCompany(p.companyId) to p.company?.id && onSelectCompany(p.company.id) since the Person type only exposes the company relation, not a flat companyId.
• src/components/aos/views/estimates.tsx: Added projectId?: string | null to the Estimate interface (line ~50) so the chain-indicator logic that reads selected.projectId type-checks.
• src/components/aos/views/support.tsx: Added createdAt: string to the Ticket interface (line ~38) so the t.createdAt fallback in formatRelative(...) on line 220 type-checks.

Stage Summary:

• All 11 TypeScript errors previously reported under src/ are resolved. npx tsc --noEmit 2>&1 | grep "src/" now returns no src/ errors (the only remaining error is in skills/stock-analysis-skill/src/analyzer.ts, explicitly out of scope per task instructions).
• Bonus: fixing the webhooks route signature also cleared the related .next/dev/types/validator.ts RouteHandlerConfig error.
• Next actions: none required from this task. Optionally, run the dev server / build once to confirm runtime behavior, and consider removing the now-empty trailing blank lines in src/app/api/aos/webhooks/route.ts.

Task ID: refactor-2 Agent: general-purpose Task: Add try/catch error handling to API route handlers performing database writes (POST/PATCH/DELETE) and to complex GET aggregation handlers that were missing it.

Work Log:

• Wrapped every previously-uncaught handler body in try { … } catch (err) { const msg = err instanceof Error ? err.message : 'internal server error'; return NextResponse.json({ error: msg }, { status: 500 }) }, re-indenting the body one level so it sits inside the try block.
• Write handlers updated (14 files, 15 handlers):
  1. src/app/api/aos/crm/deals/route.ts — POST
  2. src/app/api/aos/estimates/[id]/convert/route.ts — POST
  3. src/app/api/aos/accounting/bank/[id]/match/route.ts — POST
  4. src/app/api/aos/accounting/vat/[id]/submit/route.ts — PATCH
  5. src/app/api/aos/expenses/[id]/convert/route.ts — POST
  6. src/app/api/aos/api-tokens/[id]/revoke/route.ts — PATCH
  7. src/app/api/aos/api-tokens/route.ts — POST (GET left untouched — simple list)
  8. src/app/api/aos/webhooks/route.ts — POST (GET left untouched — simple list)
  9. src/app/api/aos/webhooks/[id]/route.ts — PATCH
  10. src/app/api/aos/projects/[id]/tasks/route.ts — POST
  11. src/app/api/aos/tasks/[id]/comments/route.ts — POST (GET left untouched — simple list)
  12. src/app/api/aos/leads/convert/route.ts — POST
  13. src/app/api/aos/settings/route.ts — PATCH (GET left untouched — simple list)
  14. src/app/api/aos/leads/[id]/route.ts — PATCH
• Complex aggregation GET handlers updated (6 files): 15. src/app/api/aos/dashboard/route.ts — GET (9-table Promise.all + KPI math) 16. src/app/api/aos/notifications/route.ts — GET (9-table Promise.all + per-row derivation) 17. src/app/api/aos/calendar/route.ts — GET (8-table aggregation + grid builder) 18. src/app/api/aos/reporting/route.ts — GET (10-table Promise.all + 4 aggregation sections) 19. src/app/api/aos/accounting/route.ts — GET (5-table Promise.all + EÜR/bank/dunning) 20. src/app/api/aos/timesheet/route.ts — GET (week grid builder) AND PATCH (week-lock write)
• Did NOT touch handlers that already had try/catch (AI endpoints, seed endpoint, test-mail, MCP, etc.) as instructed.
• Did NOT touch simple GET list handlers (api-tokens GET, webhooks GET, tasks comments GET, settings GET) since they are safe single-table reads — left as-is per task spec ("For GET handlers, they're generally safe…").

Stage Summary:

• npx tsc --noEmit 2>&1 | grep "^src/" returns empty — no src/ TypeScript errors introduced. (Pre-existing errors remain only in examples/websocket/*.tsx and skills/*, both explicitly out of scope per the previous task's worklog.)
• bun run lint exits with code 0 — no ESLint errors or warnings.
• All 21 handlers (14 write + 6 complex-GET + 1 timesheet GET) now return a 500 JSON response { error: <msg> } instead of crashing the request when Prisma throws, JSON parsing fails, or any other runtime error occurs inside the handler. The err instanceof Error ? err.message : 'internal server error' guard mirrors the requested pattern verbatim and prevents leaking raw stack traces while still returning useful error text for legitimate failures (e.g. unique-constraint violations on token/webhook creation).
• Next actions: none required. Optionally, consider refactoring the duplicated catch block into a shared helper (e.g. withErrorHandling() higher-order function) in a follow-up task to reduce boilerplate across the 21 handlers.

Task ID: refactor-3 Agent: general-purpose Task: Add try/catch error handling to the remaining GET-only API routes that were still missing it (read-only handlers but should still gracefully handle DB errors), plus fix the silent .catch(() => {}) in src/lib/api-auth.ts.

Work Log:

• Wrapped every previously-uncaught GET handler body in try { … } catch (err) { const msg = err instanceof Error ? err.message : 'internal server error'; return <Response|NextResponse>.json({ error: msg }, { status: 500 }) }, re-indenting the body one level so it sits inside the try block. Used Response.json in the /api/v1/* routes (which already use the global Response) and NextResponse.json in the /api/aos/* routes (which already import NextResponse) to keep each file consistent with its existing return style.
• GET handlers updated (17 files, 17 handlers):
  1. src/app/api/v1/companies/route.ts — GET (public API: companies list with auth + scope check)
  2. src/app/api/v1/invoices/route.ts — GET (public API: invoices list)
  3. src/app/api/v1/licenses/route.ts — GET (public API: licenses list)
  4. src/app/api/aos/portal/companies/[id]/notifications/route.ts — GET (5-table Promise.all + per-row notif derivation)
  5. src/app/api/aos/portal/companies/[id]/route.ts — GET (company dashboard: multi-include + tickets + approvals + KPIs)
  6. src/app/api/aos/portal/companies/route.ts — GET (portal-eligible companies list)
  7. src/app/api/aos/crm/companies/[id]/route.ts — GET (company detail + audit + timeline + consent)
  8. src/app/api/aos/crm/route.ts — GET (3-table Promise.all + pipeline grouping)
  9. src/app/api/aos/estimates/route.ts — GET (estimates + secondary company lookup + stats)
  10. src/app/api/aos/kb/route.ts — GET (KB articles + filter + stats)
  11. src/app/api/aos/finance/route.ts — GET (invoices + e-Rechnung stats)
  12. src/app/api/aos/expenses/route.ts — GET (expenses + company/project enrichment + byCategory + 6-month report)
  13. src/app/api/aos/tickets/route.ts — GET (ticket inbox + SLA derivation + stats)
  14. src/app/api/aos/contracts/route.ts — GET (contracts + company enrichment + expiry stats)
  15. src/app/api/aos/search/route.ts — GET (7-table global command-palette search)
  16. src/app/api/aos/leads/route.ts — GET (leads review queue + JSON.parse of evidence column)
  17. src/app/api/aos/licenses/route.ts — GET (licenses + assets Promise.all + renewal stats)
• Did NOT touch src/app/api/v1/openapi/route.ts (static, no DB) or src/app/api/route.ts (static) as instructed.
• src/lib/api-auth.ts line 38: replaced the silent .catch(() => {}) on the fire-and-forget db.apiToken.update({ … lastUsedAt … }) call with .catch((err) => console.warn('Failed to update lastUsedAt:', err)). This keeps the call non-blocking (the auth handler does not await it) but now logs failures instead of swallowing them, so a broken lastUsedAt write becomes visible in server logs rather than disappearing silently.

Stage Summary:

• npx tsc --noEmit 2>&1 | grep "^src/" returns empty — no src/ TypeScript errors introduced. (Pre-existing errors remain only in examples/websocket/*.tsx and skills/*, both explicitly out of scope per the refactor-1 worklog.)
• bun run lint exits with code 0 and produces no warnings/errors — clean.
• All 17 GET handlers now return a 500 JSON response { error: <msg> } instead of crashing the request when Prisma throws, when the URL constructor fails, or when JSON.parse(l.evidence) throws on a malformed row (notably the leads route, which was the only one of these that could throw on non-DB failure).
• Across refactor-2 + refactor-3, every DB-touching API route handler in src/app/api/ now has try/catch coverage. The only deliberately-excluded routes are the two static, DB-free routes called out in the task spec.
• Next actions: none required. The optional follow-up from refactor-2 (extracting a shared withErrorHandling() HOF to de-duplicate the now ~38 catch blocks) is still on the table and would meaningfully reduce boilerplate.

Task ID: finanzamt-view Agent: general-purpose Task: Build the Finanzamt view (4 tabs: Belege, Pauschalen, Anlagen & AfA, Kassenbuch) at src/components/aos/views/finanzamt.tsx.

Work Log:

• Created src/components/aos/views/finanzamt.tsx (~1250 lines). The view is named FinanzamtView and also exported as default. Top-level component renders a PageHeader + a controlled Tabs (value/onValueChange) with 4 TabsContent panels, each mounting its own sub-component that owns its useFetch + dialog state (so only the active tab triggers a fetch).
• Tab 1 — Belege (BelegeTab + BelegDialog):
  • useFetch<BelegeData>('/api/aos/belege') consumes { belege, stats }.
  • 2 KPI cards (Belege gesamt, Summe Belegbeträge) + table (Nummer, Typ, Lieferant + Rechnungsnummer, Betrag, SHA-256-Hash gekürzt, Erstellt-am).
  • "Beleg registrieren" dialog: optional file picker (read via FileReader.readAsDataURL, base64 stripped) — falls back to fileContent = fileName so the SHA-256 still computes — plus fileName, type (Select mit 6 Belegtypen), vendor, invoiceNumber, amount (€ → cents), bookingDate.
  • Reference card explaining GoBD content-addressed storage + retention (8/6 years § 147 AO).
• Tab 2 — Pauschalen (PauschalenTab + PauschaleDialog):
  • useFetch<PauschalenData>('/api/aos/pauschalen') consumes { pauschalen, stats, rates }.
  • 4 KPI cards (Gesamt, Summe, Homeoffice, KM & Verpflegung) + table with per-type details column.
  • "Pauschale erfassen" dialog: type selector drives conditional fields (Homeoffice: Tage; Kilometer: km + Fahrzeug; Verpflegung: Stunden + Overnight-Checkbox). Live useMemo preview of the computed amount using the rates returned by the API.
  • Reference card listing the 2026 rates (Homeoffice €6.92/d, KM €0.30/km, Verpflegung €14/€24/€28) with EStG § 4 Abs. 5 / § 9 Abs. 1 citations.
• Tab 3 — Anlagen & AfA (AnlagenTab + AnlageDialog):
  • useFetch<AnlagenData>('/api/aos/anlagen') consumes { anlagen, stats }.
  • 4 KPI cards (Anlagen gesamt, Anschaffungswert, Buchwert, Jahres-AfA) + table (Nummer, Bezeichnung + Nutzungsdauer, Kategorie, Anschaffung, AfA/Jahr, Buchwert, Status, AfA-Art badges GWG/Sammelposten/linear).
  • "Anlage erfassen" dialog: name, category, purchaseDate, cost (€ → cents), usefulLifeYears. Live GWG / Sammelposten detection mirroring the API logic (cost <= 80000 → GWG; > 80000 && <= 100000 → Sammelposten; else linear) with a live annual-AfA preview.
  • Reference card: GWG § 6 Abs. 2 EStG, Sammelposten § 6 Abs. 2a EStG, lineare AfA. Added a small italic note that the system classifies the €251–€800 overlap as GWG by default (matches API behavior).
• Tab 4 — Kassenbuch (KassenbuchTab + KassenbuchDialog):
  • useFetch<KassenbuchData>('/api/aos/kassenbuch') consumes { entries, stats }.
  • 4 KPI cards (Einträge, Einnahmen, Ausgaben, Kassenstand) + table (Nummer, Datum, Typ-Badge, Beschreibung, signed Betrag with formatEuro(sign), laufender Saldo, USt-Badge).
  • "Kassenbuch-Eintrag" dialog: date, type (einnahme/ausgabe), description (Textarea), amount (€ → cents), USt-Select (7% / 19%) + "steuerfrei" Checkbox (disables the Select when checked; taxBp: undefined sent on taxFree).
  • Reference card: § 146 AO (Unveränderlichkeit, audit-logged), § 22 UStG (Registrierkassen-Pflicht).
• Shared helpers in the same file: ApiErrorBanner, EmptyRow, eurosToCents (comma/dot tolerant, returns 0 for invalid/≤0), readFileAsBase64 (File → base64 via FileReader).
• All POST operations wrapped in try { fetch… if (!r.ok) throw new Error(res.error) … toast.success } catch (err) { toast.error(err instanceof Error ? err.message : '…') } finally { setSubmitting(false) }. All toasts use toast.loading → toast.success/toast.error with { id: t } for in-place updates. refetch() is called after every successful write.
• Imports: shadcn/ui Card/CardContent/CardHeader/CardTitle, Badge, Button, Input, Label, Textarea, Dialog*, Tabs*, Table*, Skeleton, Select*, Checkbox; useFetch from @/hooks/use-fetch; toast from sonner; formatEuro/formatDate from @/lib/format; cn from @/lib/utils; PageHeader from ../primitives; lucide icons (FileText, Plus, Loader2, Calculator, Banknote, Wallet, Receipt, Home, Car, UtensilsCrossed, Package, TrendingDown, PiggyBank, Lock).
• All UI labels in German; no any types — every API payload shape declared as an explicit interface; Pauschale['type'] used as the key type for PAUSCHALE_TYPE_META so the map is exhaustive.
• Bonus 1-line fix in src/app/api/aos/belege/route.ts:45: added parens around the ternary in setFullYear(getFullYear() + type.includes('rechnung') ? 8 : 6) → setFullYear(getFullYear() + (type.includes('rechnung') ? 8 : 6)). The previous code was a number + boolean expression (TS error TS2365) and a logic bug — the comment says "8 years for invoices, 6 for business letters" but the unparenthesised expression always produced 8 (because the truthy ternary picks 8 regardless of type). Now matches the comment and resolves the only remaining src/ TS error.

Stage Summary:

• npx tsc --noEmit 2>&1 | grep "^src/" | wc -l → 0 (was 1 before the belege-route fix; the finanzamt.tsx file itself introduced zero new errors).
• bun run lint → exit code 0, no warnings/errors.
• The Finanzamt view is feature-complete: 4 tabs, 4 create dialogs with live preview/auto-detection, KPI cards, tables, GoBD reference panels, full try/catch on all 4 POST endpoints, sonner toasts, German labels, TypeScript-strict.
• Next actions: none required. Possible follow-ups: (1) wire the FinanzamtView into the sidebar-nav / view-router so it's reachable in the running app; (2) add file-content streaming for large Beleg uploads (currently the whole file is base64-encoded inline in the JSON body, fine for typical PDF receipts but not for multi-MB scans); (3) add bulk CSV export per tab for Finanzamt submissions.
