Hermex Output Review

← all cases

scan-human-default

changed

Asserts — Baseline human output: the sections a repo gets with no output config of its own. Includes both Versus groups — a component pair and a function-only one — which is where #174 is visible: the function-only group reports a real split off files-that-import, where it used to read 0 vs 0 off JSX renders, and the package named by no lockfile entry says so instead of reporting a confident 0%.

Ran hermex scan in fixtures/ → exit 0, as asserted
