#!/bin/sh
# script/cibuild: run the CI build. The Dockerfile runs make fmt-check,
# make lint and make check (via the script/ entrypoints) as build steps,
# so a successful build implies all checks pass. The Gitea workflow runs
# this on push.
#
# That implication holds only because of CHECK_EPOCH. A COPY layer is
# invalidated by changed content, and a merge commit's tree is
# byte-identical to the branch head it merges, so without a fresh value
# here Docker serves the gate layers from cache and the build reports a
# green it never earned. Passing the current epoch invalidates the gate
# layers on every run while leaving the pinned base images and
# go mod download cached; see the Dockerfile for the placement.
