work/cluster_osrc.py mirrors build_folders.py's shape (synthesize a
refine_manifest, hand off to cmd_export_swap, relocate, merge top-level
manifest) but discovers identities by clustering rather than asserting
them by folder. Drops faces already covered by existing identity
centroids, clusters the rest at 0.55, applies refine-equivalent gates
with min_faces=6, numbers new facesets past the existing maximum so
faceset_001..NNN are never disturbed.
The 2026-04-26 run on /mnt/x/src/osrc produced faceset_020..025 (sizes
4-26 exported PNGs); analysis writeup in docs/analysis/.
README also notes the refine-renumbers caveat in passing — extend +
orchestration script is the safe pattern; cmd_refine is for fresh
clusters only.
