PostAttachment's two FKs are both ON DELETE SET NULL, so a deleted post or
artist left the row behind rather than taking it. Nothing ever pruned those
rows, and nothing in the repo had ever unlinked a file under the attachment
store — so both rows and bytes accumulated permanently, invisible to every
existing diagnostic.
Why a disk->DB reconciliation rather than a row sweep: the store is
sha-addressed and idempotent, so ONE blob backs MANY rows. Deleting a row
does not free its blob, and since the artist cascade (#3066) now deletes
its attachment rows outright, a freed blob has no DB pointer left to find
it by. Walking the store and asking "does any row still reference this
sha?" catches orphans from every cause, including ones no future delete
path will think to report.
Preview and apply share `_orphan_attachment_conditions` (rule 93). The
dry-run derives its surviving-sha set by NEGATING that same predicate, so
it is honest about blobs the delete would free rather than counting them as
still-referenced — the one place this was easy to get backwards, so it has
its own parity test.
Guards, each with a reason:
- A blob is written before its row commits, so a just-stored file legitimately
has no referencing row. Files under 6h are never judged — same guard and
reasoning as ORPHAN_TEMP_MIN_AGE_HOURS.
- `.partial` staging files belong to cleanup_orphaned_temp_files; skipped
rather than raced.
- The sha is parsed as the first 64 chars, not via Path.stem: store() takes
the extension from the source filename, and a URL-encoded basename yields a
multi-dot suffix that would make stem eat part of the sha.
- A 900s walk budget reports partial=True instead of running to the task's
hard limit (rule 89).
- TASK_STUCK_THRESHOLD_MINUTES override at 30 (= time_limit 25 + 5). Without
it a healthy 20-minute walk is phantom-flagged 'RecoverySweep' at the bare
5-min default — the #883 failure class; its invariant test is mirrored here.
Defaults to the safe preview at both the task and the route, unlike the other
maintenance triggers: this apply unlinks files. Operator-triggered only,
never on a beat.
Ships with its UI (rule 27): AttachmentReclaimCard in Cleanup → Duplicates &
leftovers, built on the existing useMaintenanceTask/MaintenanceTile shapes, so
a run survives navigating away. Surfaces files_failed and partial explicitly,
since both change what the numbers mean.
Also promotes humanBytes to utils/bytes.js — it was byte-identical in
VideoDedupCard and GatedPurgeCard and this card would have been the third
copy. The three divergent `formatBytes` helpers are deliberately left alone.

Autoscaler (agent 2026-07-02.5): the buffer-occupancy signal alone would peg
downloaders at DL_MAX while the bandwidth CAP — not concurrency — is the real
constraint (8 streams sharing 8 MB/s move no more data than 4). Growth is now
gated on the pipe having headroom (net < 85% of cap) and a pipe pinned at the
cap (>= 95%) sheds streams down to 3; dead band prevents flapping. The UI hint
says 'holding at the bandwidth cap' and /status reports bw_capped, so the
behavior is legible without tests that need the ML stack.
Reset content tagging: stays a FULL-instance reset (operator's call), but now
lives in a fenced 'Danger zone' section on Cleanup and the apply is gated by a
preview-derived confirm token (mirrors the Tier-C bulk-delete pattern — stale
counts are rejected server-side). Copy no longer claims suggestions repopulate:
it says plainly the heads' training examples are deleted and re-tagging starts
fresh. Moved out of TagMaintenanceCard into DangerZoneCard.

Goal (operator 2026-06-18): the overview of a Settings tab fits one unscrolled
viewport; expanding a tile to read into it is the only reason to scroll.
- Every Maintenance card converted to the collapsible MaintenanceTile (collapsed
by default = icon + short title + one-line blurb). Task cards (ML backfill,
centroids, thumbnails, archive re-extract, missing-file repair, DB maintenance)
sit in a responsive grid; running tasks auto-expand. Tagging config (suggestion
thresholds, allowlist, aliases) grouped in one Tagging section as collapsible
tiles; Backup is its own collapsible tile.
- Three labeled sections mirror the Cleanup tab: Backfills and reprocessing /
Tagging / Storage.
- Center the whole Settings surface: SettingsView is now a centered, width-capped
(1140px) column so the tab strip and every panel sit in a tidy centered measure
(was full-width). CleanupView drops its own left-aligned max-width to fill it.
All card logic unchanged - only the chrome.

The Cleanup + Maintenance sections had ~17 full-width stacked cards with long
descriptions — a hunt to scan. Operator wants compact, sectioned, scannable tiles
(2026-06-18: keep both tabs, group inside, compact tiles in a grid).
New common/MaintenanceTile.vue: a compact expandable tile (icon + short title +
one-line blurb collapsed; click the header to expand the full controls/preview/
result inline; keyboard-accessible button + focus ring; tints the
icon, keeps a running task expanded).
Cleanup tab (this pass) restructured into 3 sections — Import-filter audits
(Min dimensions, Transparency, Single-color) / Duplicates & posts (Bare posts,
Duplicate posts, Deduplicate videos, Gated-post previews) / Tags (Unused, Legacy,
Reset content tagging, Standardize casing) — each a responsive grid of tiles.
PostMaintenanceCard split into 2 tiles, TagMaintenanceCard into 4. Moved
VideoDedupCard + GatedPurgeCard from the Maintenance tab here (both are
destructive content cleanup). All card logic unchanged — only the chrome.
Maintenance tab tiling is pass 2 (TODO noted in MaintenancePanel).

The muted-text token was redefined identically in 12 component <style scoped>
blocks. Consolidate to one global utility in styles/app.css; remove the 12
copies. Keeps the explicit on-surface-variant (vellum) token, NOT Vuetify's
opacity-based text-medium-emphasis (per the muted-text-token rule). Behavior-
preserving: every class=fc-muted usage now resolves to the single source.
§8b exhaustiveness caught (and I fixed) my own sed clobbering the new app.css
rule — now exactly one .fc-muted definition exists, zero component-local.
Catalog updated.

The native Patreon backfill flooded the feed with bare 'Post <id>' shells
(1589 for Anduo). Root cause: PostAttachment.sha256 was GLOBALLY unique, so a
non-art file reused across posts only ever linked to the first one, and
_capture_attachment created the Post before that dedup check — leaving later
posts with no image and no attachment. Duplicate IMAGES had the mirror gap:
attach_in_place returned duplicate_hash/duplicate_phash before _apply_sidecar,
so the second post got no provenance row, and the feed only rendered via
primary_post_id (one post per image).
Operator requirement: a duplicate item must show on EVERY post it appears in.
Unify the fix as link-not-suppress:
- importer: on duplicate_hash / duplicate_phash(larger_exists), append an
image_provenance row for the new post (keep primary on the first). Both the
download path (attach_in_place) and the filesystem path (_import_media).
- post_feed_service: render thumbnails by image_provenance UNION primary_post_id,
so a cross-posted image shows on every post (and legacy primary-only images
still show).
- PostAttachment: per-post uniqueness — drop UNIQUE(sha256), add partial
UNIQUE(post_id, sha256) + partial UNIQUE(sha256) WHERE post_id IS NULL
(migration 0043); _capture_attachment dedups per-(post,sha) over the shared
sha-addressed blob, so no post is left bare.
- cleanup: new prune-bare-posts maintenance action (cleanup_service
_bare_post_conditions shared by preview/count/delete per preview/apply parity;
admin endpoint; PostMaintenanceCard). Deletes posts with zero image links
(primary or provenance) AND zero attachments. Run after the feed fix so a
hidden provenance link spares the post instead of deleting it.
Tests: dup image shows on both posts; dup attachment shows on both posts; feed
renders provenance-linked duplicates; prune-bare delete-path == preview.
Operator redeploys (migration 0043) then runs the prune to clear the shells.
