# Builds the upstream jetstream development simulator (cmd/simulator): a
# deterministic fake atproto network (PLC + PDS + relay) under one HTTP
# listener.
#
# Upstream publishes the jetstream server image to GHCR but not the
# simulator binary, so this image is built locally by the e2e lifecycle
# controller from the same pinned upstream source commit as the server
# release. If upstream (or a jacquard publish) ships a simulator image,
# set E2E_JETSTREAM_SIM_IMAGE to it and this build becomes unused.
#
# Build context: the extracted upstream source tarball at the commit
# recorded in scripts/e2e.sh (JETSTREAM_UPSTREAM_COMMIT).
