Atomic extraction of the deadline-rule compute engine + types from
internal/services into a new pkg/litigationplanner package that paliad
+ youpc.org can both import. No behaviour change — every existing test
passes against the post-move shape.
Package contents (~1850 LoC):
- doc.go package docstring + reuse manifesto
- types.go Rule, ProceedingType, NullableJSON, AdjustmentReason,
HolidayDTO, CalcOptions, CalcRuleParams, Timeline,
TimelineEntry, RuleCalculation*, FristenrechnerType,
ProjectHint, sentinel errors
- catalog.go Catalog interface (proceeding + rule lookups)
- holidays.go HolidayCalendar interface
- courts.go CourtRegistry interface + DefaultsForJurisdiction +
country/regime constants
- expr.go EvalConditionExpr + HasConditionExpr +
ExtractFlagsFromExpr (jsonb gate evaluator)
- durations.go ApplyDuration + AddWorkingDays (pure compute)
- subtrack.go SubTrackRouting + LookupSubTrackRouting registry
- legal_source.go FormatLegalSourceDisplay + BuildLegalSourceURL
- proceeding_mapping.go MapLitigationToFristenrechner + code constants
(CodeUPCInfringement, CodeDEInfringementLG, ...)
- engine.go Calculate + CalculateRule + the trigger-event
branch + applyRuleOverrides (the big move)
paliad side (~1900 LoC net deletion):
- internal/services/fristenrechner.go shrinks from 1505 → ~290 lines
(thin paliad Catalog adapter + type aliases for back-compat).
- internal/models/models.go: DeadlineRule, ProceedingType, NullableJSON
become type aliases to litigationplanner.* — every sqlx scan and
every projection_service caller compiles unchanged.
- internal/services/holidays.go: AdjustmentReason + HolidayDTO become
aliases to lp.* (canonical definitions now in the package).
- internal/services/proceeding_mapping.go: rewritten as thin re-exports
of lp constants + helpers.
- internal/services/deadline_search_service.go: FormatLegalSourceDisplay
+ BuildLegalSourceURL replaced with delegating wrappers to lp.
Catalog interface satisfaction:
- DeadlineRuleService → paliadCatalog adapter (wraps the existing
service, replicates the original SELECT shapes).
- HolidayService → satisfies lp.HolidayCalendar directly (compile-
time assertion at end of fristenrechner.go).
- CourtService → satisfies lp.CourtRegistry directly.
Wire shape is byte-identical. JSON tags on Rule / ProceedingType /
Timeline / TimelineEntry / RuleCalculation match the historical
UIResponse / UIDeadline shape; the frontend reads the same bytes.
Slice B (Catalog interface + paliad loader cleanup) is folded into
this commit since Slice A already needs the interfaces to call
Calculate across the boundary. Slice C (embedded UPC snapshot +
generator) is the next coder shift; the Berufung unification m
called out lands in Slice B/C per head's brief.

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.
Stack
- Frontend: Bun + custom JSX/TSX renderer (no React), per-page client TS bundles, HTML-first forms
- Backend: Go (
net/http),sqlxfor DB access - Migrations:
golang-migrate/migrate/v4with SQL files embedded viaembed.FS; applied at server startup before the HTTP listener binds - Database: youpc Supabase Postgres,
paliadschema. Office-scoped RLS (paliad.can_see_akte(akte_id)) — seedocs/design-kanzlai-integration.md§2 - Auth: Supabase password (cookie session,
@hoganlovells.com/@hlc.*email gate) - CalDAV: hand-rolled iCal + minimal WebDAV client in
internal/services/caldav_*.go; AES-GCM at rest for stored passwords - Hosting: Dokploy compose

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.
