Replaces the golang-migrate single-counter tracker with a hand-rolled runner over embed.FS that tracks applied state as a set in paliad.applied_migrations (version PK, name, applied_at, checksum). Closes the parallel-merge skip-hole the 2026-05-20 mig-103 incident exposed (m/paliad#44): a migration whose version is missing from applied_migrations runs on the next deploy regardless of which higher versions are already applied. Gaps are first-class. Slice 1 of the design at docs/design-migration-runner-applied-set-2026-05-20.md. All eight design decisions m-picked = inventor recommendation. Runner contract: - Ensure paliad schema → pg_advisory_lock(hash('paliad.applied_migrations')) → CREATE TABLE IF NOT EXISTS applied_migrations. - bootstrapFromLegacyTracker: if applied_migrations is empty and the legacy paliad.paliad_schema_migrations row is present and clean, INSERT rows 1..N for every on-disk version with checksum=NULL via ON CONFLICT DO NOTHING. Hard-fail if legacy tracker is dirty (operator must recover). - scanEmbeddedMigrations: hard-fail on two .up.sql files sharing a version prefix — the failure mode the post-mortem exposed. - checkNameAgreement: hard-fail on rename-after-apply mismatch (disk name for an already-applied version != DB name). - applyOne: SQL body + INSERT(version, name, now(), sha256(file_bytes)) in one transaction. All-or-nothing per migration. Checksums populated on apply for future drift detection; rows backfilled from the legacy tracker carry NULL (we can't fabricate a hash for what golang-migrate applied historically). Verify-on-deploy intentionally deferred to a focused follow-up — single if-block flip when m wants it. Up-only runner. .down.sql files stay in embed.FS as reference; manual roll-back path is psql + DELETE FROM paliad.applied_migrations WHERE version=N. Zero call sites for migrate.Down in the codebase today. Drops github.com/golang-migrate/migrate/v4 from go.mod (no other importers; verified via grep). Tests: - internal/db/migrate_test.go: TestMigrations_DryRun walks pending = on_disk \\ applied (read from paliad.applied_migrations, missing-table → empty set), runs each in BEGIN/ROLLBACK against the scratch DB. - cmd/server/main_smoke_test.go: TestBootSmoke asserts the applied set equals the on-disk set exactly (not just max-version-match) — catches the skip class the post-mortem documented. Dirty-flag check removed (rows are committed or absent, not 'dirty'). - All 45 service-test call sites of db.ApplyMigrations work unchanged (same signature, same fresh-DB behavior). Follow-up: mig 108_drop_legacy_trackers (DROP paliad.paliad_schema_migrations and public.paliad_schema_migrations) after one or two deploys of burn-in on this slice.
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.
