DOI https://doi.org/10.17632/n7kmd7t7yx.1 Source snapshot records CC-BY-4.0. Retain appropriate credit and license link, describe modifications, do not imply endorsement. Dataset modifications: canonical parsing, existing writer split, lowercase eligibility filtering, source TRAIN median-height normalization, canonical stroke traversal/order,32-point per-stroke arclength sampling; local neural training then float32 Java export. Labels/source identity grouping remain unverified as documented. No additional legal conclusion is made here. Specific observed glyphs in this example: inputs agmt and corrections qfjr. 18 remaining letters are neural predictions. Writer research code isgl:002.

ISGL Online and Offline Character Recognition Dataset (2019), by Ibrahim Adeyanju, Elijah Omidiora, Olusayo Fenwa, Omodolapo Babalola, Opeyemi Durodola. https://doi.org/10.17632/n7kmd7t7yx.1. CC BY 4.0: https://creativecommons.org/licenses/by/4.0/. Observed agmt retained; same-writer observed corrections qfjnrilIkK; 14 neural lowercase glyphs. Actual observed capital I added. Shared guide normalization, Java 32-point resampling, smoothing and TrueType outline conversion; no endorsement. Existing model-training credits also apply to 14 neural glyphs. Font curation: same-writer recorded uppercase K from isgl:capitals:icr_008_K_2_1 supplies uppercase K and an intentional capital-form lowercase k (K-to-k remapping). Original source label K and raw stroke provenance retained. This replaces the previous neural k for legibility; it is not a model improvement. Added 24 observed uppercase glyphs from the SAME writer isgl:008. Source CC BY 4.0 https://creativecommons.org/licenses/by/4.0/. New capitals are recorded handwriting, not neural output. Existing glyph shapes remain unchanged. IDs and original strokes are in capital_supplement_manifest. Prior counts describe the earlier project; final project has 38 observed and 14 neural glyphs.

Source handwriting: CC BY 4.0 https://creativecommons.org/licenses/by/4.0/. Writer isgl:004. This font has 52 recorded-source letters (A-Z and a-z), zero neural letters. Modifications: same-writer exemplar selection, shared guide normalization, 32-point resampling, smoothing, typographic placement and TrueType outline conversion. Lowercase t is an explicit optical edit of source icr_004_t_2_2: initial stem extended by 36% and left crossbar arm by 14% of original height along their existing tangents, preserving its curved foot and tail. The unedited recording and edit parameters remain in the project provenance. This is not a recovered stroke or a neural prediction. No endorsement implied.
