+# Integrity: the file is checked against its declared byte count and sha256
+# (the LFS oid from the Hub, 2026-09-28). NO AUTH HEADER IS USED: the repo is
+# public and ungated, and a token on the curl command line is world-readable
+# via /proc/<pid>/cmdline. If this ever needs a token, put it in a mode-600
+# file and pass it with `curl -K`.

+# Layout after a successful run (MODEL_DIR):
+#   Swift-1.5-Qwen3.8-27B-Uncensored-Dynamic-MTP-UD-Q8_K_XL.gguf  31457990272
+#
+# This is the CANDIDATE payload, not the deployed one. frank-large still
+# serves scripts/download-frank-large.sh's output; do not repoint
+# frank-large.env at MODEL_DIR until the gufo load test passes.
