Cleanup pass per design §7 / S6, executed as a measured first cut
that drops the cascade endpoint + neutralizes the legacy Pathway B
row-stack / cascade init without lifting the entire ~1500 LoC
subtree out of `fristenrechner.ts`. The dead helpers stay for one
follow-up that can lift them safely.
Backend:
* Deleted `internal/handlers/fristenrechner_event_categories.go`.
* Dropped the `GET /api/tools/fristenrechner/event-categories`
route from `handlers.go`. The `EventCategoryService` itself
stays — it still backs the legacy concept-card search's
`?event_category_slug=` filter, which dies in the same
follow-up that removes the concept-card response shape.
* `paliad.event_categories` TABLE is untouched per design §7
(kept for future tools).
Frontend:
* `loadEventCategoryTree()` reduced to a stub returning `[]` — the
endpoint it fetched no longer exists, and no overhaul surface
calls it.
* `initB1Cascade()`, `initForumFilter()`, `initInboxFilter()`
early-return. Their `DOMContentLoaded` registrations stay so
the bundle exports are stable, but no Pathway B cascade /
chip-strip / inbox-channel wiring fires in `?legacy=1` mode.
* The Pathway B markup in `fristenrechner.tsx` stays in place; it
renders inert when a user hits `?legacy=1&path=b`.
* `buildRowStack`, `renderRowStack`, `runB1Search`, and the row-
stack helper functions remain as unreachable code. Removing
them mechanically requires retiring the entire upper-half
Pathway B B2 search wiring (`runSearch` + `renderConceptCard`
+ `renderSearchResults` + `SearchResponse` types) which is
tangled with the legacy concept-card response shape — deferred
to a follow-up that lands together with the backend
concept-card removal.
Verified — bun build clean (2971 i18n keys unchanged), 256
frontend tests pass, go build + vet clean, live-DB tests
(TestListProceedings, TestSearchEvents, TestLookupFollowUps)
still green.
Follow-up scope tracked in design §7 S6 — pending the helper-tree
lift and the legacy concept-card response-shape removal from
/search.
