Lighter mesh for phones: tools/build.py --coarsen N (and UNROLL_STEP) keeps every Nth sampled row and column of a built mesh with the same UV mapping; PHerc0172 lite mesh 527,834 vertices (from 2,082,140), 1.5 MB packed, loaded automatically on phones via geometry.lite (?mesh=full or ?mesh=lite overrides); tear threshold follows the mesh step

Public API at window.unroll (schema, help, coverage test; ui and bench groups), embed mode with postMessage bridge and oEmbed, version 0.9.4 in About and API, ink_9um (9 µm) label and credit, Ink Bench hardening from the audit, hashchange without reload, capped test hooks
Overlay textures upload through a per-frame queue (about 6 ms per frame, initTexture) instead of all at once, removing the 14.6 s main-thread freeze; import map versions for tear.js, damage.js and lib/*.js; scan shown as 9.4 µm with 9.362 µm voxels in the details; glossary links every occurrence; mobile panel clears the bottom bar
Relabel the second ink layer as ink_9um (9 µm): Chase Hendrick ran the public scrollprize/ink_9um model, which the Vesuvius Challenge trained; HUD readout INK_9UM; cache-busting version on JS and CSS
Multi-scroll support: build.py and fetch.py take any open-data scroll (per-scroll voxel size, X-ray scan, renumbering by radius, optional ink, a second 1 um ink layer), make_manifest.py, the scroll picker's prize eligible badge and eligible-only toggle (window.unrollScrolls), and a 'Why N ink layers?' box written from each manifest's ink layers
Faster first load: ship the int16 geometry as byte planes + gzip (scroll.i16p.gz, 1.62 MB instead of 3.48 MB), unpacked in the browser to the exact scroll.bin bytes with a fallback to scroll.bin; tools/pack_bin.py builds it, tests/pack_bin.mjs checks the round trip
Ink Bench: examples on all 37 windings, researcher takeaway (rank by AP, report the X-ray floor), ink_9um credit, untrack pycache, sturdier leaderboard test
Ink Bench: score your own ink prediction against the published ink, in the browser, with a Python and CLI companion, an open bundle format, a leaderboard view and Apache-2.0 code
- scrolls/index.json registry and per-scroll manifests (windings with ranges, ink layers with sources and resolutions, credits, data terms); PHerc. 139 migrated with no visible change
- scroll picker (hidden with one scroll), per-scroll and per-winding lazy loading
- lib/manifest.js validator shared by the page and tools/validate_scroll.mjs; docs/ADDING_A_SCROLL.md; tools/precompute_template.py
- Open your own: files, folders, zips or a URL, read in the browser only (nothing uploaded), OBJ/PLY with UVs, PNG/JPG/TIFF layers, size limits, clear errors, kept in IndexedDB and labelled local; downloadable synthetic example package
- atlases as WebP with JPG fallback (about 2.1 MB smaller)
- rename layers: Published ink (2.4 µm) and Our ink model (9 µm)
