PHercParis4 whole-scroll unroll, ufsm coarse-to-fine (c2f), 2026-10-31
=====================================================================

PARTIAL / STOPPED: this upload was stopped on 2026-10-31 at the owner's request right after it started. Only this README
landed; the truncated strip/strip.sfc from the interrupted transfer was removed.
No renders were uploaded. The layout below describes the intended set.
Scan: PHercParis4/20260411134726-2.400um-0.2m-78keV-masked.zarr, level 2 (9.6 um). Supersedes
volcomp/PHercParis4/segments/ufsm-c2f-20261030 (left in place).

Method: wind96 network fields (phase, normals, density) -> global count-field reference model -> slab fits snapped to the
reference with all fit fixes (phase gate, build 2c54b28; no ct-cal) -> fit-join -> per-wrap surfaces -> one continuous
spiral strip (ufsm strip --last 179) -> strip-flatten (chunked SLIM + blend) -> render (CT + ift3-24000-ov8 ink, holes filled
along the normal and inpainted; filled pixels are inpainted, not data) -> strip-mosaic.

Scores (pod logs):
  GT check against the published Paris 4 wraps: winding ids right 0.1622; same-sheet pairs within 0.5 mm 0.675, 4 mm 0.301
  join: integer agreement on the slab overlaps 0.931
  wrap-check: CT papyrus peaks per fitted turn 1.056 overall (1 = right); 1.01-1.14 from 0 to 24 mm, 0.99-0.71 from 24 to
    30 mm; verdicts 137 real, 12 dup, 0 merged.
  Outer-end duplicate wraps dropped: wrap-check flags w180-w191 as duplicated outer turns, so the strip stops at w179
    (--last 179).
  strip: 133 wraps w179 -> w047 (outermost first), 343514 x 4449 vertices, flattened 1103.0 cm x 20.3 cm,
    mesh area 19842 cm2, aniso p50/p95 1.07/1.18, flips 0.0067% of area
  renders: 20 stripes at 9.6 um/px, valid 19155 cm2 with fill, on papyrus (CT >= 80 within 3x3 px) 0.729; ink = ift3-24000-ov8

Layout (per the owner, this upload carries only the JPEG renders and the final spiral surface):
  strip/strip.sfc       the continuous spiral surface (+ strip.json, strip.tsv per-wrap column ranges)
  renders/rgb_fill/     filled CT+ink mosaic: overview.jpg (strip folded into 10 rows), overview_8000.jpg,
                        strip_long.jpg (one row), wsNNN_ct_ink.jpg (per stripe, full res, CT above ink)
  renders/papyrus/      papyrus-colour mosaic: overview.jpg, overview_8000.jpg, strip_long.jpg, wsNNN_papyrus.jpg
No per-wrap surfaces, 3D ink zarr or fit/spiral field zarrs are included.
