PHercMAN5 whole-scroll unroll, ufsm coarse-to-fine (c2f), 2026-10-31
=====================================================================
Scan: PHercMAN5/20260311104824-2.399um-0.2m-78keV-masked.zarr, level 2 (9.596 um). Supersedes the 10-28 corpus run (volcomp/PHercMAN5/representations/ufsm-c2f-20261028, left in place).

Method: wind96 network fields (phase, normals, density) -> global count-field reference model -> slab fits snapped to the
reference (fit-fix build, ufsm master ad6198f, which includes the 3b40993 phase gate and the 2c54b28 OOM guards) -> fit-join
-> per-wrap surfaces (ufsm wraps, --min-cm2 0.5) -> one continuous spiral strip (ufsm strip) -> strip-flatten (chunked SLIM
+ blend) -> render (CT + ift3-24000 ink, holes filled along the normal and inpainted) -> strip-mosaic.

Scores (pod logs, tsv/):
  join: integer agreement on the slab overlaps 0.842
  wrap-check: CT papyrus peaks per fitted turn 0.861 overall (1 = right); 0.64 at 0-1 mm, 0.94-1.00 from 1 to 6 mm, 0.92-0.65 from 6 to 14 mm, falling at the outer edge (the fit counts more turns than the CT shows sheets there); verdicts 61 real, 15 dup, 0 merged.
  Outer-end duplicate wraps: dropped. wrap-check flags w119-w131 as duplicated outer turns (and w132-w150 have ~0 papyrus), so the strip stops at w118 (--last 118) and wraps/ holds w056-w118 only. w056-w057 at the inner end are also flagged dup and kept.
  strip: 63 wraps w118 -> w056 (outermost first), 78397 x 1785 vertices, flattened 239.6 cm x 7.5 cm, mesh area 1356 cm2, aniso p50/p95 1.06/1.31, flips 0.084% of area
  renders: 5 stripes at 9.596 um/px, valid 1323 cm2 with fill, on papyrus (CT >= 80 within 3x3 px) 0.570
