URGENT bug: /deadlines/{id} rendered "Frist nicht gefunden oder keine
Berechtigung" while the underlying /api/deadlines/{id} returned 200, and
/deadlines list showed "Invalid Date" in the date column.
Root causes — same class as t-paliad-038, this time on deadlines and
appointments client TS:
1. parseFristID/parseTerminID still checked URL prefix "fristen"/"termine".
After t-paliad-025 renamed pages to /deadlines and /appointments,
parts[0] no longer matched → null id → notfound branch fired before any
API fetch. Renamed to parseDeadlineID/parseAppointmentID with the
correct "deadlines"/"appointments" prefix.
2. fmtDate in deadlines.ts blindly appended "T00:00:00" to the API's
due_date string. After the v2 schema, the API returns full ISO
datetime ("2026-04-22T00:00:00Z"), and "...ZT00:00:00" is invalid →
"Invalid Date". Guarded both fmtDate and urgencyClass with
iso.length === 10 / iso.slice(0, 10).
3. Half-renamed variables (`let allDeadlines` declared, `allFristen`
used; `let deadline`, `frist` referenced). Worked at runtime only
because the undeclared identifier became a non-strict global. Cleaned
up to use the declared English names everywhere.
Lockstep DOM ID + variable rename in client TS + matching TSX:
- frist-* → deadline-* (deadlines-detail, deadlines, deadlines-new,
deadlines-calendar)
- termin-* / termine-* → appointment-* / appointments-* (appointments-detail,
appointments, appointments-new, appointments-calendar)
- fristen-body/empty/unavailable → deadlines-* (list page)
- termine-body/empty/unavailable → appointments-* (list page)
- frist-cal-grid / termin-cal-grid → deadline-cal-grid /
appointment-cal-grid (calendars)
- loadFristen/loadTermine/loadAkten/loadFrist/loadTermin/loadAkte →
loadDeadlines/loadAppointments/loadProjects/loadDeadline/loadAppointment/loadProject
- deadlines.ts: dropped unused projekt_office field from Deadline interface
- appointments.ts: dropped unused projekt_office field from Appointment
interface
Dashboard cleanup — Go service was still emitting `projekt_ref`:
- internal/services/dashboard_service.go: UpcomingDeadline /
UpcomingAppointment / ActivityEntry json+db tags `projekt_ref` →
`project_reference`; SQL aliases `AS projekt_ref` → `AS project_reference`.
- frontend/src/client/dashboard.ts: interfaces switched to
project_reference; activity link href /projects/{id}/fristen →
/deadlines, /termine → /appointments (the German per-project subpaths
were dead — t-paliad-038 already renamed projects-detail tabs).
i18n key strings (fristen.*, termine.*) intentionally kept in German per
the t-paliad-025 convention (frontend default language is German). CSS
class names (frist-row, frist-due-chip, frist-cal-cell, termin-dot,
termin-type-*, akten-table-wrap) untouched — separate stylistic cleanup,
no IDs are referenced in CSS so the rename is safe.
Verified: go build/vet/test clean, bun run build clean, dist HTML
contains only the new English IDs (remaining German strings are i18n
keys and product-name CSS classes).
