D1 scheduler visibility: AppSetting last-tick stamp on every Beat tick +
GET /api/sources/schedule-status (last_tick_at/next_due_at/due_now/auto_sources)
+ SchedulerStatusBar on the Subscriptions tab (re-polled every 30s).
D2 failing-source rollup: ?failing=true on the sources list + FailingSourcesCard
on Downloads with per-source and bulk "retry" (re-runs the feed via /check).
D3 activity sparkline: GET /api/downloads/activity hourly buckets + CSS bar
chart by the stat chips (failures stacked in error color); refreshes on live poll.
D4 credential staleness: surface last_verified age + "re-verify recommended"
warning past 30d; also fixes the dead last_verified_at field-name mismatch so
the verification row renders at all.

Operator-flagged 2026-05-28: the Subscriptions/Downloads dashboards were
full-bleed and thin on filtering. Chosen via AskUserQuestion.
**Layout**
- SubscriptionsView capped at a centered max-width 1600px (covers all
three subtabs) so rows aren't a mile wide on ultrawide monitors.
- Sticky control headers on both tabs (top: 48px, below the top nav,
opaque bg) so filters/stat-chips stay reachable while scrolling a
long list.
**Downloads filters (all four requested)**
- Stat chips are now clickable filters: click Queued/Running/Completed/
Failed/Skipped to filter the list to that status; the active chip is
outlined + elevated; re-click clears.
- Free-text search box over the loaded events (artist / platform /
error substring).
- Artist filter: the filter popover's numeric "Source ID" field is
replaced with an artist autocomplete (sources.autocompleteArtist →
artist_id, which /api/downloads already supports). Pill shows the
artist name.
- "Show no-change scans" toggle (default OFF): hides status=ok/skipped
rows with 0 files (the scheduled scans that found nothing) so real
downloads + failures stand out.
**Subscriptions**
- "Needs attention" quick-filter chip: one click to show only artists
with sources that have errors OR have never been checked; chip shows
the count and disables the status dropdown while active.
Frontend-only — backend filter params (status/artist_id/date) and the
/api/downloads endpoint already supported everything.
Operator-flagged 2026-05-28, two asks.
**1. Credential Verify (was missing vs GS — and now actually verifies).**
GS's Verify was a stub (`TODO: implement actual verification` — just
stamped last_verified). FC does a real check, which matters given the
recent auth pain (subscribestar age cookie, HF host-only PHPSESSID):
- GalleryDLService.verify(url, platform, cookies_path, auth_token) runs
gallery-dl in `--simulate --range 1-1` mode (no download) against the
URL with the materialized credentials, then reuses _categorize_error:
returncode 0 / NO_NEW_CONTENT → valid; AUTH_ERROR → invalid; other →
inconclusive (reason surfaced). 45s timeout.
- POST /api/credentials/<platform>/verify picks an enabled Source for
the platform to probe, runs verify, and on success stamps
credential.last_verified (new CredentialService.mark_verified).
Returns {valid: bool|null, reason, last_verified?}. valid=null means
untestable (no credential, or no enabled source to point at).
- CredentialCard gains a Verify button (on credentialed cards) + a
result chip (Verified ✓ / Failed / Untestable) and a toast with the
reason. SettingsTab reloads on @verified so last_verified refreshes.
**2. Live download-activity feedback.** The Downloads tab was static —
no way to tell if downloads were succeeding without manually hitting
Refresh. It now auto-polls: stats every 4s, and the event list too
while anything is queued/running. Polling pauses when the tab is
backgrounded (document.hidden) and the list reload is skipped on idle
ticks to stay light. A pulsing "● live" indicator next to the stat
chips shows when auto-refresh is active (queued+running > 0); honors
prefers-reduced-motion.
Tests: verify endpoint — untestable with no credential, untestable with
no enabled source, valid+stamped on success (gallery-dl mocked), and
auth-failure reported without stamping.
Operator-flagged 2026-05-27: the Downloads subtab "doesn't feel like a
dashboard" — status was a tiny mdi icon at the far left, platform chip
was neutral-tonal, errors were plain orange text floating on the right,
and all 28 rows from the same hour visually had the same priority.
**Row restyle (A):**
- 4px colored left-edge bar by status (success/error/info/warning/grey)
— visually scannable at the edge without parsing the chip text
- Status chip with text label (Completed/Failed/Running/Queued/Skipped)
+ leading icon, tonal-colored. Replaces the bare mdi-icon.
- Platform chip swapped to the color-coded subscriptions/PlatformChip
(Patreon=red mdi-patreon, SubscribeStar=amber, HentaiFoundry=purple,
Discord=indigo, Pixiv=blue, DeviantArt=green).
- File count: tonal info chip when > 0, dim middle-dot when 0 (so
scheduled "no-change" scans don't dominate the column visually).
- Error: red tonal pill chip with leading icon, truncated to 60 chars
with full text in the title tooltip. Replaces plain text.
- Per-row actions (hidden at 50% opacity, fade to full on row hover):
Retry (only when status=error AND source_id known — hits
POST /api/sources/<id>/check via the existing sources.checkNow),
Details (opens the detail modal), Open artist (navigates to the
artist page). Clicks stop-propagation so they don't bubble to the
row click.
**Date-grouped sections (B):**
- Events are bucketed into four sections: Today / Yesterday /
Last 7 days / Earlier. Empty buckets are skipped. Buckets boundaries
are computed against the operator's local-time start-of-day so
"Today" matches their intuition.
- Each section has a collapsible header with a row-count chip + a
red "failed in this section" chip when any failures are in scope.
- Within each section, status='error' rows are pinned to the top
(operator's eye lands on failures first; successful scans flow
below).
- Collapsed state persists across refresh within the SubscriptionsView
lifetime (reactive object, default all-expanded).
DownloadEventRow grid widened to accommodate the status chip + actions
column. PolyMasonry-style ellipsis on the artist link prevents long
names from breaking the layout.
No new endpoints; the Retry path reuses the existing /api/sources/<id>/check
flow (the source-check endpoint was already in place, just not wired
into a per-row button).
Replaces the three top-level routes with a single `/subscriptions` parent
owning the whole download-pipeline domain. Internal tab state via `?tab=`
query param, mirroring ArtistView's pattern. TopNav auto-drops the two
removed entries (route-driven via meta.title). Bookmark-safe redirects
from `/credentials` and `/downloads` route into the appropriate subtab.
**Subtab 1 — Subscriptions (default).** Carries over the existing
artist-grouped expandable table; adds (a) status filter dropdown, (b)
bulk-select column with Enable/Disable/Delete-all actions, (c) GS-style
color-coded `PlatformChip` per distinct platform in the collapsed row.
Reuses SourceRow, SourceHealthDot, SourceFormDialog, ArtistCreateDialog.
**Subtab 2 — Downloads.** Full GS dashboard. Five colored stat chips up
top (Queued/Running/Completed/Failed/Skipped, sourced from new
`GET /api/downloads/stats?window_hours=`). Popover-style filter UI
(Status/Source/FromDate/ToDate) with active-filter pills below.
Maintenance menu wraps existing /api/import/retry-failed and
/api/import/clear-stuck endpoints; Export-failed-logs item disabled with
a "v2" tooltip. Per-row Retry preserved via existing DownloadEventRow.
**Subtab 3 — Settings.** Four sections: ExtensionKeyBar (top), GS-style
per-platform CredentialCard grid (md=6 v-row/v-col, dashed border if
unset / accent border if set, expandable how-to panel), Downloader card
(rate limit, validate_files), Schedule defaults card (default interval,
event retention, failure warning threshold). The Downloader and Schedule
sections were extracted out of components/settings/ImportFiltersForm.vue
— SettingsView's Import tab now owns only image-import filters.
**Backend:** new `GET /api/downloads/stats` returns
{pending, running, ok, error, skipped} count grouped by status over the
configurable window. Status keys stay raw from the ENUM; UI does the
display-label mapping. Two integration tests pin the response shape +
window_hours validation.
**Util:** `frontend/src/utils/platformColor.js` — single source of truth
for the six platforms' color + icon + label, mirroring GS's palette
(patreon=red mdi-patreon, subscribestar=amber mdi-star,
hentaifoundry=purple mdi-palette, discord=indigo mdi-discord,
pixiv=blue mdi-alpha-p-box, deviantart=green mdi-deviantart). Unknown
platform falls back to grey + mdi-web.
Deferred (explicit non-goals): subscription import/export, "Trigger Due
Now" scheduler-tick button (needs new backend endpoint), Export Failed
Logs CSV dump.
