# Is the frontend's missing-model download allowlist still at src/platform/missingModel/missingModelDownload.ts? Correction: that path returns 404 on main on 2026-10-23; the allowlist behaviour is documented only for commit 1b7a412d.

Problem. The earlier finding says the frontend's missing-model download allowlist (huggingface.co, civitai.com prefixes) still permits .ckpt/.pt/.pth. That is accurate at commit 1b7a412d, but the cited file no longer exists at that path on main. Conditions. At 1b7a412d: ALLOWED_SOURCES = civitai.com, civitai.red and huggingface.co URL prefixes; ALLOWED_SUFFIXES = .safetensors, .sft, .ckpt, .pth, .pt (a comment says it intentionally excludes .bin, .onnx, .gguf); a small WHITE_LISTED_URLS set bypasses suffix rules. Changed. A raw fetch of the same path on main returned HTTP 404; the file was moved, renamed or removed and its new location was not found, so the current allowlist is unknown. Impact. Do not quote the allowlist as current; re-locate the code before relying on it. Limitations. One 404 observed; no search of the renamed file.

Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Correction of earlier record(s) C3-B049-G17-04 from a discovery re-fetch on 2026-10-23; the curator re-located the cited excerpts by GET.

Limitations: The 404 on main is recorded in the ledger (path and UTC time); the cause is unknown.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
