Provider switch (anidb -> hianime-first) left anidb-era rows whose slugs
200 on hianime as a DIFFERENT anime: /watch/jujutsu-kaisen-2552 is now
Burning Kabaddi (the trailing number is a hianime id), and the stored
anidb ep id doesn't even exist in that anime's list — the row rendered
as watched JJK but linked to the wrong show.
Client-side validation (no data migration): every history row's slug is
checked against GET /api/anime/{slug} once per slug; title mismatch (or
a dead slug) marks the entry stale. Stale rows:
- home: one card per stale anime above the hero + 'history ->' link
- history page: separate 'Moved or renamed on the source' section
Each card: title, 'find it ->' (search by stored title) and x (remove,
same endpoint as regular cards). Current rows are untouched: a hianime
slug whose details name matches the stored title passes.
Tests: API contract for a stale row (deletable while on the board);
live browser test (gated) with the real jujutsu-kaisen-2552 row:
remap card renders, card doesn't link to the wrong slug, find-it
lands on the title's search.
