Add OpenModelDB (openmodeldb.info) as a metadata and download source for
the existing upscaler model type.
Metadata:
- New OpenModelDBClient: fetches the site's bulk JSON dumps, caches them
on disk (24h TTL + ETag revalidation), and builds a local sha256 index
- New OpenModelDBModelMetadataProvider adapts catalogue entries to the
CivitAI-shaped version dict contract; registered in the fallback chain
behind the enable_openmodeldb_api setting (default on), gated to the
upscaler sub-type so other model types never trigger the dump download
- Persisted provenance uses metadata_source "openmodeldb" plus a nested
openmodeldb block (page URL, architecture, scale, license)
Images: paired-image LR/SR URLs are ephemeral imgdiff.net sessions, so
displayable images come from the site-hosted auto-generated thumbnails
(model-level cover leads images[], per-image thumbs for the rest); the
original comparison URL is kept in meta.comparisonUrl.
Downloads:
- New OpenModelDBSource (flat model ids, omdb: group prefix) with
resource filename derivation that recovers names hidden mid-path
(mediafire) or synthesizes {id}.{type} for folder links
- HTML-gateway mirrors (mediafire/mega/drive) are rejected with a clear
manual-download hint instead of silently saving an HTML page as .pth
- ModelSource base gains is_valid_source_id / default_subdir_parts /
resolve_download_url hooks so flat-id sources need no platform branches
UI: "View on OpenModelDB" link in the model modal (downloaded and
hash-enriched models), settings toggle next to the CivArchive one.
A model could have CivitAI metadata and a HuggingFace link at the same time,
but only one of the two "View on ..." entries ever rendered, because both the
model modal and the card globe asked the `from_civitai` provenance flag which
source to show. `set_hf_url` wrote `false` and a CivitAI refresh wrote `true`,
so whichever ran last erased the other: linking HF hid "View on CivitAI" even
though the civitai payload was still in the sidecar, and (on the card) a later
refresh pointed the single globe icon back at CivitAI, hiding the HF entry.
Decide the links from the data itself instead:
- `set_hf_url` no longer touches `from_civitai`; it records where the metadata
came from, and HF provenance is already tracked by `hf_url`.
- Add `hasCivitaiSource(civitai)` in the shared card/modal utils and gate the
modal's CivitAI link, the card globe (title, enabled state, click target,
new `data-has_civitai`) and the context-menu `civitai` action on actual
CivitAI data (`modelId` / `model_id` / `id`). A dual-source model now shows
both links, and a CivitAI-only model with no `hf_url` stays as before.
- Agent HF enrichment (`PostProcessor.is_hf_model`) keyed off
`not from_civitai`, which stopped being a synonym for "has an HF source" once
both sources can coexist (and already broke after a CivitAI refresh flipped
the flag back to true). Key it off `hf_url` directly; the post-processor
tests move to that discriminator and gain a dual-source case.
Regression tests: the set-hf-url handler preserves civitai + `from_civitai`
and no longer forces the flag false, the modal renders both links (including
with `from_civitai: false`), and the card globe targets/opens the right source
and is disabled when neither is available.
