deploy/redeploy.sh deploys main only if every new commit is signed by a key
in deploy/allowed-signers, and finds out after CI. On 2026-10-09 that held
learn.halkyon.eu at v0.2.2 for two days: 37 commits had reached main
unsigned, and every deploy since refused them. tool/check_signatures.sh
applies the same rule to a push, to the commits it brings to main that the
remote doesn't have yet (the list as the pushed commit has it), and
tool/check.sh runs it first when it runs as the pre-push hook: a second,
where the rest takes minutes. CI runs check.sh under its own name and
skips it.
