Five small G5 findings from the 2026-06-02 audit. Each is local and
follows an established FC pattern.
- download_service: replace hardcoded ('discord','pixiv') tuple with
auth_type_for(platform) == 'token'. A 7th token-platform now picks
up the right credential path without touching this site.
- /api/tags/<source_id>/merge enqueues recompute_centroid.delay after
merge so the target's centroid reflects its new image set
immediately. Daily list_drifted catches it within 24h, but eager
recompute closes the suggestion-quality dip in the meantime.
- backfill_thumbnails added to beat_schedule (daily). The task
docstring claimed periodic Beat but the entry was never registered,
so the library got no self-healing thumbnail repair; only the
manual admin-UI button fired it.
- modal.createAndAdd pushes a kind='fandom' tag into
tagsStore.fandomCache so FandomPicker sees the new fandom on next
open. Was: cache-gated load (length===0) skipped refetch, new
fandom invisible until full page reload.
- cleanup cluster:
- Drop .webp from cleanup_service.unlink — thumbnailer only writes
.jpg/.png; the third tuple member was dead code.
- Drop effective_date from /api/gallery/scroll response — no FE
consumer reads it. Service still computes the attribute for
timeline ordering; this just trims the JSON.
- Rename store.recentMinute → store.recentRuns across the
systemActivity store + three consumers (SystemActivitySummary,
QueuesTable, SystemActivityTab). The data is the last 200 runs
(not actually "last minute"), so the name lied.
NOT in this bundle: the duplicate tag-merge endpoint
(/api/tags vs /api/admin/tags) is harder — has 1 FE caller and 3 tests
on the admin variant; consolidation is its own change.
