Schema-only landing for Slice 1 of the CalDAV multi-calendar design
(docs/design-caldav-multi-calendar-2026-05-19.md). Sync engine NOT
touched — Slice 2 wires the per-binding fan-out. After this migration:
- paliad.user_calendar_bindings — N bindings per user with scope_kind
∈ {all_visible, personal_only, project, client, litigation, patent,
case}. Hierarchy scopes anchor scope_id at paliad.projects(id).
Partial unique indexes enforce one binding per (user, scope_kind,
scope_id) for hierarchical scopes and one per (user, scope_kind)
for the scope-less roots. RLS mirrors user_caldav_config.
- paliad.appointment_caldav_targets — per-(appointment, binding) join
carrying caldav_uid + caldav_etag. UID stays canonical per
appointment so the same event in N cals shares one UID.
- Backfill — one all_visible binding per existing user_caldav_config
row, one target row per appointment already pushed. Maps target to
the creator's binding, matching today's Phase F semantics where the
creator's goroutine owns the etag.
Legacy paliad.appointments.caldav_uid / caldav_etag columns are
untouched (kept as denormalised pointers through Slice 1+2; dropped
in Slice 4 after telemetry).
Dry-run verified against live Supabase (PG 15.8): synthetic config +
appointment backfill creates exactly 1 binding + 1 target; re-run is a
no-op; all CHECK + unique-index constraints enforce as designed; final
assertions pass with 0 missing rows.
Prod impact at landing: 0 rows in user_caldav_config and 0 appointments
with caldav_uid — backfill is a true no-op. Slice 1 ships invisible.
paliad
Paliad — all-in-one patent practice platform for HLC (formerly Hogan Lovells). Knowledge tools and Aktenverwaltung behind one sidebar.
- Aktenverwaltung: Akten (matters), Fristen (deadlines), Termine (appointments) with CalDAV sync, Parteien, Dashboard. Office-scoped visibility with explicit collaborators.
- Knowledge tools: Prozesskostenrechner (DE / UPC / EPA), Fristenrechner, Gebührentabellen, Patentglossar, Gerichtsverzeichnis, Checklisten, Link Hub, Downloads.
Domain: paliad.de (legacy: patholo.de, patholo.msbls.de).
Repo: m/paliad on mgit.msbls.de.

Database migrations
Migrations live in internal/db/migrations/ as NNN_description.up.sql + .down.sql pairs. They are embedded into the Go binary via embed.FS and applied automatically at server startup (before the HTTP listener binds) when DATABASE_URL is set.
The migration tracker is paliad.paliad_schema_migrations (not the default public.schema_migrations). This avoids a collision with other apps on the shared youpc Supabase instance — see the memory episode "paliad migration bootstrap collision with shared Postgres" for the incident that drove the change.
Current migrations (as of April 2026):
001_paliad_schema schema + extensions
002_users paliad.users (office, role, practice_group)
003_reference_tables proceeding_types, deadline_rules, holidays
004_akten paliad.akten with visibility columns
005_akten_children parteien, fristen, termine, dokumente, akten_events, notizen
006_visibility paliad.can_see_akte() function
007_rls_policies RLS on every paliad table
008_seed_proceeding_types
009_seed_deadline_rules 32 UPC + 4 ZPO rules
010_seed_holidays DE federal + UPC judicial vacations
011_feedback_tables link_suggestions, checklisten_feedback, gerichte_feedback
012_fristenrechner_rules DB-backed rule set for /tools/fristenrechner
013_user_caldav_config per-user CalDAV (encrypted) + sync log
014_checklist_instances persisted checklist instances linkable to Akten
Add a new migration:
internal/db/migrations/015_<description>.up.sql
internal/db/migrations/015_<description>.down.sql
The down file is required and must reverse the up cleanly (verified by adding a one-off down test before merge).
To run migrations against a local Postgres:
docker run -d --name paliad-pg -e POSTGRES_PASSWORD=test -p 5432:5432 postgres:16-alpine
# bootstrap a mock auth schema (auth.users + auth.uid()) — required because
# the migrations reference Supabase-provided objects:
psql postgres://postgres:test@localhost:5432/postgres -f internal/db/devtools/mock_supabase_auth.sql
DATABASE_URL='postgres://postgres:test@localhost:5432/postgres?sslmode=disable' \
SUPABASE_URL=stub SUPABASE_ANON_KEY=stub \
go run ./cmd/server
Environment
| Variable | Required | Purpose |
|---|---|---|
PORT |
no (default 8080) | HTTP listen port |
SUPABASE_URL |
yes | Supabase project URL (auth) |
SUPABASE_ANON_KEY |
yes | Supabase anon key (auth) |
DATABASE_URL |
for Aktenverwaltung | Direct Postgres conn for migrations + Akten/Fristen/Termine services. Knowledge-platform endpoints (Kostenrechner, Glossar, Links, Gebührentabellen, Checklisten, Gerichte, Downloads) don't use the pool and work without it. Aktenverwaltung endpoints return 503 if unset. |
CALDAV_ENCRYPTION_KEY |
for CalDAV sync | 32-byte AES-256 key, base64-encoded. Encrypts CalDAV passwords at rest (AES-GCM). Server fails fast on malformed key; if unset, CalDAV is silently disabled (/api/caldav-config returns 501). Generate with openssl rand -base64 32. |
GITEA_TOKEN |
optional | Gitea API token for the private file proxy (Downloads) |
ANTHROPIC_API_KEY |
not used today | Reserved for Phase H (AI Frist-Extraktion). Currently deferred — do not set. |

Project status (April 2026)
Phases A–G, I and J of the KanzlAI integration are shipped: schema, services, Akten, Fristen, Termine + CalDAV, Dashboard, Notizen service + UI (commit 5a9f8e5, 2026-04-17), and instanceable Checklisten (migration 014). Phase H (AI Frist extraction) is deferred pending a reversal of the "no Anthropic API" decision; the Dokumente tab on Akten detail is hidden until that lands. KanzlAI infra retirement (Dokploy shutdown, kanzlai schema drop, Gitea archive) is still pending.
See docs/feature-roadmap.md for the full backlog and docs/design-kanzlai-integration.md for the integration design.
