On a CivitAI/CivArchive 429, download-model and download-model-get now
return HTTP 429 with {"reason": "rate_limited", "retry_after": N}
instead of a generic 500 string, and the queue row goes back to
"queued" rather than history as failed — so queue drivers can
auto-pause and retry later instead of burning through the queue.
- new DownloadRateLimitError carrying retry_after/host (opt-in via
raise_on_rate_limit on Downloader; other call sites keep the legacy
string behavior)
- fail-fast pre-flight gate in DownloadManager consults
RateLimitCoordinator before acquiring the semaphore slot: hosts in
cooldown get an immediate structured 429, no HTTP request attempted
- best-effort 429 detection for the aria2 backend
