 "limitations": [
  "The cache records no catalog, code revision or image list, so 'same catalog as the frozen observations' is read off the current worktree, not attested by the cache.",
  "Only 155 of 4580 crops produced a local candidate; the other 4425 are decided by the text lane alone or refused before any gate applies, so the accept floor is exercised on a small minority of the rows and the rates are dominated by empty evidence.",
  "The catalog is 12 rows from one store. A false-accept rate is a function of catalog size, so these numbers do not transfer to a larger or differently-stocked catalog.",
  "Crops come from one detection pass at detect_conf 0.1 on 1280-long-side frames, so the crop population is set by the detector, not only by the identity gate.",
  "The cache has no per-photo breakdown, so no photo-level rate and no check that one image is not carrying the whole count.",
  "The near-argmax fallback is a research construct in analyze.py, not shipped code; its row prices a policy that does not exist on the server yet.",
  "far-unknown-lines.json's producer is not in the tree, so agreement with it is corroboration, not verification."
