Mode B "🧭 Geführt" — the guided 3-5 row wizard defined in
docs/design-fristenrechner-overhaul-2026-05-26.md §3.2. Lands the
user on a single procedural_event (the trigger), then transitions
to the shared §4 result view.
Frontend:
* `fristenrechner-wizard.ts` — row stack with R1..R5:
R1 Was ist passiert? (event_kind, always asked)
R2 Vor welchem Gericht? (jurisdiction, skip if R1 narrows)
R3 In welchem Verfahren? (proceeding_type, auto-skip when
narrowed pool has 1 option)
R4 Welches Schriftstück? (procedural_event, landing)
R5 Welche Seite vertreten Sie? (party, only when follow-ups
differ by primary_party)
Row badges per §11.Q3: R1+R2 = Filter, R3+R4+R5 = Qualifier.
R5 has NO "Beide" option per §11.Q8 — Mode B is the file-mode
where perspective is a qualifier.
* Project prefill — derives R3 + R2 jurisdiction from
project.proceeding_type, R5 from project.our_side. Annotates
pre-filled rows with "aus Akte" tag and implicit rows with
"implizit" tag per §11.Q10 ("erhalten" annotation when a pick is
carried across an upstream change).
* R4-to-result transition — after R4 the wizard fetches /follow-
ups (no dates) to inspect primary_party variance. If both
claimant and defendant rules exist AND R5 isn't already set,
swaps the loading row for the R5 chip picker. Otherwise jumps
straight to mountResultView.
* URL state — `?mode=wizard&kind=…&forum=…&pt=…&r4=…&party=…`
keeps deep-link / back-nav consistent (the launchResult step
sets `event=` so the result view picks up).
* `fristenrechner-result.ts` mountModeShell now dispatches the
"wizard" tab to the wizard module (was a coming-soon
placeholder).
* 18 i18n keys added (DE + EN parity), 145-line CSS block for the
wizard row stack with Filter / Qualifier badge styling and
"aus Akte" annotation chip.
Backend:
* `ProceedingListOptions.EventKind` adds an EXISTS subquery
filter on `paliad.sequencing_rules` ⨯ `paliad.procedural_events`
so Mode B R3 chips only show proceedings whose event roster
contains at least one event of the requested kind (design
§6.3). Endpoint param: `event_kind=` on
/api/tools/proceeding-types.
Test updates:
* `TestListProceedings` switched from SKIP-when-column-missing to
asserting the live filter — mig 153 has landed, `kind` column
is in place. New subtests: kind=proceeding includes
upc.inf.cfi and excludes the phase row upc.cfi.interim;
event_kind=filing narrows to proceedings with filing events.
* `fristenrechner-wizard.test.ts` covers
`followUpsDifferByParty` — the R5 trigger predicate. 7 cases:
asymmetric → true; uniform / both / court / empty → false.
Verified — bun build clean (2971 i18n keys), 256 frontend tests
pass (incl. 7 new), go build + vet clean, live-DB
TestListProceedings passes all 6 subtests against mig 153 data.
