The task

regexp-tree parses, traverses, transforms, optimizes and generates regular expressions, and its fa module builds NFA/DFA tables for a toy sub-language (no flags, no captures). What it has never had is a matcher of its own: regexpTree.exec hands the string to the host RegExp. Build one. Add src/engine/ exposing compile(pattern, flags?), re-exported as regexpTree.engine and as regexpTree.compile(...). pattern may be a…

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.
