# Runs the runner's generated-file drift checks against the EXACT build
# context the image builds see — same .dockerignore semantics — so a
# context-slimming change that strips a committed build input fails the
# pull request instead of every post-merge image build. (2026-09-04: a new
# `packages/paperclip-runner/**/*.md` ignore rule stripped the committed
# capability contract out of the context; every Docker build on master then
# failed its drift check, and no cloud image published for eight hours
# while PR CI stayed green.)
#
# Only checks whose compared output is independent of dependency versions
# run here: ajv is installed for schema VALIDATION only (pinned to the
# runner's declared range), while codegen checks like
# generate-protocol-schema-module stay out — their emitted bytes vary with
# the ajv release, so running them against a fresh install would raise
# false drift alarms. Those still run inside the real image build, which
# installs the locked dependency tree; the existence assertions below keep
# their committed inputs and outputs covered by this probe regardless.
#
# node:24-slim — the runner requires Node >= 24.11 and the production
# image builds on Node 24; the digest pin keeps the security gate's own
# runtime immutable.
