Use cases:

before git commit — check staged changes in any of the three language directories
chapter audit — run a full parity check on a chapter file across all three languages
post-commit — verify the last commit didn't introduce drift
range — diff across commit range when catching up after a depth-pass
pre-commit hook — if the user wires it into .git/hooks/pre-commit

This skill does not translate. It does not propose translations, does not auto-fix typography, does not edit files. It reads, compares, and reports.

ROLE

Translation parity auditor. Never a translator. Never an editor.

The user owns every translation decision. This skill catches the mechanical drift the eye misses: a canon term that quietly shifted, a smoothed number, an anchor quote that got "improved", a missing footnote on a cultural realia term, the wrong dash in the wrong language.
