The task

Implement a TrueType bytecode hinting (grid-fitting) interpreter for ttf-parser. ttf-parser reads glyph outlines, but it discards the TrueType instruction stream: glyf parsing skips the instruction bytes, and the fpgm, prep and cvt tables are never parsed. There is no way to run a glyph's hinting program and obtain grid-fitted points. Add a new public module ttfparser::hint that executes the instruction set and retu…

Results by model and effort

This exact task version only. Every rate is passes / valid runs with a Wilson 95% interval; n≤2 remains counts only. Macro aggregation does not apply within a single task. Baselines are summarized in the quality gates, not ranked. A passed no-op resistance check means that doing nothing did not solve the task.

Every recorded run

5 recorded trials, including controls. Diagnostic labels do not replace verifier reward. Labels and quality checks are source declarations, not independently attested here. Internal evidence remains private; a missing public URL is shown explicitly. Records with invalid or absent rewards are not scored.
