ignoreExportsUsedInFile did not only exempt exports used inside their own
module; until 6.28.0 it also marked every re-export as referenced in its
own file, so a barrel line nothing imported was never reported. The
upgrade took this repo from 0 findings to 206 on unchanged code. Write it
down next to the setting, because a green gate on any earlier knip proved
nothing about re-exports.
Also correct the production-pass file count, which had drifted to 21.
The runtime fetch extracts databases in pure Node, but its unit test
builds a MaxMind-shaped tar.gz fixture with the system tar, which the
dead-code gate flagged as an unlisted binary. It is available in CI and
dev, alongside the docker and pg_isready entries already listed.
Vitest is a knip plugin, so every file under `src/**/__tests__/**` is an
entry, and a module whose only importer is its own test counts as used
for as long as the test survives. Planting a module with a single test
importing it left `pnpm knip` at exit 0 — the gate reports green on code
production stopped reaching.
Knip can answer the question, just not in the pass CI runs: production
mode drops the plugin's test entries and keeps the entry and project
patterns suffixed with `!`. Mark them, which is inert in the default
pass, so `pnpm knip --production --include files` is one command away.
It stays a review tool rather than a second gate, and the config says
why: twenty-nine files today, some test-only by construction and some
unreachable from production on purpose, plus at least one false positive
where a script's `@/` import does not resolve. Baselining that set
unread would encode noise as an invariant.
Move the config to JSONC so all of the above lives next to the settings
it describes instead of in a commit message nobody will run `git log`
for.
