With many models, or models on a network drive, every visit to the scan
page read every folder and, after a restart, every new model's header
again (79 s for 1041 models on an AutoDL model disk).
api/model_heads.py keeps what each file's header says by real path, size
and time in user/anomalous/model_heads.json (at most 50,000 files, the
longest unused dropped first, written a few seconds after the last
change, only once setup_routes called keep_on_disk); get_metadata reads
headers through it, so a header is read once per file version.
scan_summary keeps the last summary (memory, and scan_summary.json when
it changed); ?quick=1 hands it out at once and the page shows it with
"showing the last counts while they are updated", then the fresh ones.
Requests meanwhile await one count (_fresh). The models found on Civitai
(components apart, at most 5000 kept) are listed by GET
/anomalous/scan_matched; the page's "Found on Civitai" count opens them,
with Civitai's name, base model, a box to find one by name and Open.
Checked on the isolated ComfyUI reading the real loras and checkpoints
read-only (scans stubbed; no file there changed): the last counts showed
at once also after a restart, the fresh ones replaced them, the found list
had 68 models with names, the box filtered, Open and Back returned to it.
