Closes the search half of the unified Fristenrechner. Phase D (concept-card
UI on /tools/fristenrechner) follows in a subsequent shift.
Migration 047:
- Seed the missing `wiedereinsetzung` concept and re-point the four
Wiedereinsetzung trigger_events (200..203) at it. PR-7 referenced
the slug `re-establishment-of-rights` but never seeded the concept,
so the four cross-cutting triggers were dropping out of any concept-
JOINing query. Per m's slug rule (Q1: shared cross-cutting concepts
use DE slug because German term dominates HLC vocabulary).
- Create paliad.deadline_search materialised view: UNION ALL of
(deadline_rules joined to deadline_concepts) and (trigger_events
joined to deadline_concepts via slug). Trigram GIN indexes on
legal_source / concept_name_de / concept_name_en / rule_name_de /
rule_name_en / rule_code; gin (concept_aliases) for array
containment; UNIQUE INDEX on a synthetic row_key so refresh can
run CONCURRENTLY.
Refresh strategy: data only mutates via migration files at server
startup, so no AFTER triggers and no pg_cron — main.go calls
services.RefreshSearchView right after db.ApplyMigrations. CONCURRENTLY
keeps reads online and stays well under 100 ms at < 1k rows.
Service `internal/services/deadline_search_service.go`:
- Two-query pipeline per request: (1) rank concept_ids by
GREATEST(similarity()) across name / aliases / legal_source / rule_code
plus a 0.2 alias-hit boost; (2) load all matview rows for the top-N
concepts and assemble per-pill JSON.
- normalizeQuery strips legal-prefix noise (`§`, `Art.`, `Section`,
`Rule `) so users typing `§ 82` find DE.PatG.82.1 even though the
structured legal_source column doesn't carry the prefix.
- FormatLegalSourceDisplay renders structured codes back to the
pleading form HLC users expect:
UPC.RoP.23.1 → "UPC RoP R.23(1)"
DE.PatG.82.1 → "PatG §82(1)"
EU.EPÜ.108 → "EPÜ Art.108"
EU.EPC-R.79.1 → "EPC R.79(1)"
EU.RPBA.12.1.c → "RPBA Art.12(1)(c)"
- Drill URLs route per kind: rule pills → ?proc=…&focus=…, trigger
pills → ?mode=event&triggerId=…
Handler `GET /api/tools/fristenrechner/search?q=&party=&proc=&source=&limit=`:
- Returns the JSON shape from design §6.1 (cards-with-pills).
- 503 with friendly DE message when DATABASE_URL is unset, mirroring
the other Fristenrechner endpoints.
- Empty q returns an empty cards array (browse surface is Phase D).
Tests:
- Pure-Go: TestFormatLegalSourceDisplay (12 cases across all known
prefixes) + TestNormalizeQuery (8 cases).
- Integration (skipped without TEST_DATABASE_URL): golden table
pinning the design's binding queries — Klageerwiderung returns the
statement-of-defence card with UPC.RoP.23.1, DE.ZPO.276.1,
DE.PatG.82.1, EU.EPC-R.79.1, DE.PatG.59.3 pills; "RoP 23" returns
the same card; "§ 82" → normalized "82" → BPatG hit; Wiedereinsetzung
returns one card with exactly 4 trigger pills (ids 200..203);
party / source filters narrow as expected; limit cap honoured.
- SQL semantics validated against live data via supabase MCP using a
CTE-inlined matview definition with the slug fix simulated; results
match the golden table.
Per design doc `docs/plans/unified-fristenrechner.md` §4.6 (matview
shape) + §6 (search ranking + API).
