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.
