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
Fix ~790 basedpyright errors across the test suite:
- Type stub subclasses of real production classes with super().__init__()
- Add missing generic type arguments and Dict[str, Any] annotations
- Add None guards before subscript/member access
- Adapt tests to production API changes (removed dead handlers,
PersistentModelCache.get_default, _i18n_filter_added location)
- Read AutoV3 directly from the downloaded file's own file_info hashes
(no SHA256 cross-matching against version_info.files, so the value is
captured even when the API omits SHA256)
- Extract normalize_autov3() validation helper shared with the
sha256-matching autov3_from_civitai_files path
- Fall back to the embedded safetensors header hash at download
completion; mark '' (checked-unavailable) so the startup backfill
query (autov3 IS NULL) never revisits the row
- Clear archive-level AutoV3 for zip-extracted models so per-file
header resolution applies to every extracted model
