Grammar tables: one authored pattern, two runtimes, proven per vector

↗ view on GitHub · Eli Ziff · 2026-07-29 · 013aca10

The cross-runtime contract that makes shared grammars safe: Python
compiles with re.ASCII and JS without the u flag, pinning digit, word,
and boundary classes to identical semantics; named groups are authored
JS-style and translated for Python; the validator bans what genuinely
diverges. Two pilot grammars ride the whole pipe with shared vectors;
the round-trip test executes both runtimes, and the validator caught
its first real authoring error before the first commit. Python loader
lives in the engine subrepo.
