m's 2026-05-26 decisions:
- Q1 composition: primary+spawned (v1) with multi-proceeding peer compose as v2 goal — jsonb spec architected for N entries from day 1
- Q2 scope: per-project + abstract (project_id NULL = abstract saved templates)
- Q3 dates: per-anchor overrides over one base date (matches today's compute)
- Q4 storage: new paliad.scenarios table with jsonb spec (NOT project_event_choices column extension)
- "users should not add their own rules" — original Slice E (user-authored rules) DROPPED, replaced with abstract scenarios surface on /tools/verfahrensablauf
§5 rewritten with new schema (paliad.scenarios + active_scenario_id FK), jsonb spec shape (proceedings[] array, version-tagged), validate-on-load discipline, multi-peer v2 path. §6 struck-through with original body preserved as historical context. §10 slice plan revised: Slice E = abstract scenarios surface, not user-authored rules. §0.5 added with decision matrix; §13 marked resolved.
Package shape (§2 §3) unchanged — library was decoupled from persistence/UI choices by design.
Inventor design for m/paliad#124. Atomic extract of FristenrechnerService /
DeadlineCalculator / proceeding_mapping / SubTrackRoutings / legal-source
helpers into pkg/litigationplanner with Catalog / HolidayCalendar /
CourtRegistry interfaces. youpc.org reuse via embedded UPC snapshot
(catalog.json + holidays.json + courts.json) shipped inside the package.
6 slices: A extract, B catalog interface, C embedded snapshot + generator,
D scenarios persistence (project_event_choices.scenario_name), E
user-authored rules (deadline_rules.project_id), F youpc-side PR.
Q1 + Q2 (material) escalated to head per inventor protocol — NOT
AskUserQuestion. Q3-Q5 locked. Decision picks (R) noted; doc holds together
under any answer to the open Qs because pkg shape is decoupled from
persistence choices.
