A scenario is a named composition of existing proceedings + flags +
per-card choices + anchor dates. Users compose, they don't author —
spec references existing rules by submission_code; never creates new
rules. Per m's 2026-05-26 AskUserQuestion picks (doc commit 6e58595):
Q1 composition: primary + spawned (v1); multi-proceeding peer
compose is the v2 goal (spec.proceedings[] array)
Q2 scope: per-project + abstract (project_id NULL = abstract)
Q3 trigger: per-anchor overrides over one base date
Q4 storage: NEW paliad.scenarios table with jsonb spec
(NOT a project_event_choices column extension)
Migration 145 — additive only. Pre-flight coordination check:
- On-disk max: 138 (Berufung backfill, just merged).
- Live DB tracker: 106 (significantly behind — many migs pending
deploy).
- curie's #93 B.2-B.6 migs not pushed yet — reserved 139-143 + 144
as buffer; claimed 145 as the safe minimum that won't collide.
- paliad.scenarios has audit_reason NOT applicable (no audit
trigger on the table); updated_at trigger added on the table
itself.
- paliad.projects gains active_scenario_id uuid NULL FK with ON
DELETE SET NULL (mig 134 lesson — no updated_at clauses on
proceeding_types-style assumptions).
Schema:
paliad.scenarios (
id uuid pk,
project_id uuid NULL FK → projects(id) ON DELETE CASCADE,
name text NOT NULL CHECK char_length > 0,
description text NULL,
spec jsonb NOT NULL CHECK jsonb_typeof = 'object',
created_by uuid NULL FK → users(id) ON DELETE SET NULL,
created_at + updated_at timestamptz,
UNIQUE NULLS NOT DISTINCT (project_id, created_by, name)
);
paliad.projects.active_scenario_id uuid NULL FK;
RLS: project-scoped → can_see_project; abstract → created_by = auth.uid();
Trigger: scenarios_touch_updated_at_trg.
pkg/litigationplanner additions:
- Scenario struct (db + json tags)
- ScenarioSpec / ScenarioProceeding / ScenarioCardChoice — parsed
view of the jsonb (version-1 today, v2 multi-peer-ready)
- ParseSpec(raw) + ScenarioSpec.PrimaryProceeding() + CalcOptionsFromSpec()
- ScenarioFilter + Catalog.LoadScenarios + Catalog.MatchScenario
- CalculateFromScenario(scenario, catalog, holidays, courts) — high-
level engine entry: parses spec → builds CalcOptions → delegates
to Calculate
- Sentinel errors: ErrUnknownScenario, ErrInvalidScenario,
ErrScenarioNoPrimary
paliadCatalog impl:
- LoadScenarios with progressively-built WHERE clauses (project-id
filter, abstract-for-user filter, or all)
- MatchScenario by id — returns ErrUnknownScenario on not-found
- Services connection bypasses RLS; ScenarioService enforces
visibility at the application layer (mirrors EventChoiceService
pattern from t-paliad-265)
SnapshotCatalog impl (embedded/upc):
- LoadScenarios returns empty slice (no scenarios in the snapshot)
- MatchScenario returns ErrUnknownScenario
internal/services/scenario_service.go:
- Create / Get / ListForProject / ListAbstractForUser / Patch /
SetActive / Delete with visibility checks
- validateSpec checks version, base_trigger_date format, every
proceedings[*].code resolves to an active paliad.proceeding_types
row, every appeal_target is valid, every anchor_overrides date
parses, every role ∈ {primary, peer}
- SetActive validates the scenario belongs to the requested project
(a scenario from a different project can't be active here)
- Returns ErrScenarioNotVisible for failed visibility checks
REST endpoints (registered in handlers.go):
GET /api/scenarios?project=<id> — list project's
GET /api/scenarios?abstract=true — list user's abstract
GET /api/scenarios/{id} — one
POST /api/scenarios — create
PATCH /api/scenarios/{id} — partial update
DELETE /api/scenarios/{id} — remove
PUT /api/projects/{id}/active-scenario — set / clear active
Handler error mapping:
- ErrUnknownScenario / ErrScenarioNotVisible → 404
- ErrInvalidInput / ErrInvalidScenario / ErrScenarioNoPrimary → 400
- everything else → 500
Tests:
- pkg/litigationplanner/scenarios_test.go: ParseSpec roundtrip
(well-formed + unknown version + malformed json),
PrimaryProceeding zero/multi/single, CalcOptionsFromSpec full
unpack, trigger_date_override path, no-base-trigger safety check.
8 cases total, all DB-free.
Wired in cmd/server/main.go alongside EventChoice — same pattern,
nil-safe when DATABASE_URL is unset (handlers 503 in that mode).
Acceptance:
- go build ./... clean
- go test ./... all green (incl. new scenarios tests)
- Pre-flight audit confirmed mig 145 number is safe vs curie's
pending B.2-B.6 range
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.
