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.

Architecture Topic Guide
Start with the repository-root ARCHITECTURE.md, then
open only the topic needed for the current task.
backend.md: Python routes, filesystem safety, persistence, scan state, model sidecars, and backend performance.frontend.md: extension bootstrap, UI ownership, localization, media lifecycle, panel state, and graph mutations.recipes.md: Workflow Recipes, packages, galleries, Parameter Notebooks, prompt roles, and recipe-to-model transitions.material-library.md: saved prompts and node values (material files), keeping an output image, and dragging prompts onto the canvas.recipe-model-lifecycle.md: authoritative model fields, Hash synchronization, local matching, partial append, and note privacy.model-resolution.md: model provenance, Model Check, hash injection, model scanning, and recovery policy.../decisions/README.md: concise records of product and architectural decisions that still explain current behavior.
These documents describe current contracts rather than implementation history.
For exact changes, use Git history. For user-visible releases, use
CHANGELOG.md. For recurring implementation traps, use
