+# Per-stage lane output dirs — the SCRATCH tier of working-files.md, in bulk.
+# characters/work/lena/v02/ alone is 1,019 MB: 15 .blend snapshots of the same
+# ~883k-vertex mesh (48_headsafe, seamed, reatlased, 52_transplant, 55_fix1/2/3,
+# rigged, rigged_fix1/2/3, rigged_fullres, ...) plus their .glb exports. Exactly the
+# growth the rule was written to stop — the lane hit 3.0 GB once before, 2.2 GB of it
+# .blend files. The 48-55 recipes ARE the history and rebuild any of these from
+# masters/55_fullres_v02.blend, which is pinned in .lanekeep and tracked.
+# If a v02 artifact is ever registered in characters/REGISTRY.md, `git add -f` it —
+# nothing here is registered yet (the v03 body is HELD with known defects).
