The on-device search index grew unbounded over a long session. putRows now
prunes each touched room to MAX_ROWS_PER_ROOM (5000) — deleting the oldest rows
by [roomId, ts] via a self-chaining IDB cursor within the same write tx (never
awaits a non-IDB promise mid-tx, so the transaction can't auto-commit and
truncate the prune). Exposed a pure, unit-tested evictCount() for the decision;
the cursor path itself is browser-only (node --test has no IndexedDB).
Deliberate tradeoff (documented in code): the coverage window keeps claiming the
evicted tail so the search doesn't re-fetch → re-evict it forever. Net effect —
in a room past 5000 cached rows, an evicted old message is silently unsearchable
rather than churning. Clear cached index / logout still wipe everything.
Two review agents verified the IndexedDB-spec correctness (cursor delete+continue
semantics, put-then-count ordering, roomRange bracketing with no prefix bleed,
tx liveness, abort→cache-miss) since CI can't. Gate-green (tsc, eslint, prettier,
925 tests, build).

Web fixes from the Wave-2 bug-hunt (findings in LOTUS_TODO):
- F1 (security): wipe the decrypted-plaintext search index on SERVER-FORCED
logout too (token expiry / remote sign-out) — only manual logout did before.
F4: the delete no longer reports success while onblocked (waits, 3s cap).
- M1/M2 (data-loss): useBookmarks + useUserNotes account-data writes are now
serialized at MODULE scope (single queue + latestRef per client, echo-driven),
fixing the cross-instance lost-update clobber (useBookmarks mounts per message
row, so a per-instance queue was insufficient — caught in review).
- M6: room-history export gets a 200-page cap + Cancel + unmount-abort +
correct date-range early-break (raw paginated ts). M4: image compression
skips PNG (was flattening transparency to black), bakes EXIF orientation via
createImageBitmap, .jpg-renames, and falls back to the original on decode
failure instead of dropping the file. M5: MediaGallery lightbox opens the
right item (shared thumb guard). M8: audio speed survives async decrypt.
- Desktop web wiring: D2 badge sums leaf rooms only (space double-count, like
the favicon fix); D3 useTauriDnd re-hydrates from get_tray_dnd on mount; D5
updater has a terminal state.
Reviewed; M7 reverted (past-time clamp is an intentional, tested contract).
tsc/eslint/prettier clean, build OK, 678 tests.

Raw-IndexedDB cache (lotus-search-cache: messages keyed [roomId,eventId] +
per-room coverage) merged into local search with in-memory-wins dedupe. OPT-IN
(default off) via a standalone atom — stores decrypted text at rest, so it ships
with a privacy note, a Clear button, and an unconditional wipe on logout
(initMatrix). All IDB errors degrade to cache-miss. +8 tests (1 IDB skip in node).
