Scoping the image tag was never sufficient on its own. Every build read one unscoped directory in the working tree, into which each run copies the binaries it just built, so two concurrent runs raced on the contents of the context as well as on the name of the result — and a run could produce a correctly-per-run-tagged image built from the other run's binaries. The run now copies the context's tracked files into its own directory, installs its binaries there, and builds from it, exporting the path so every other consumer follows. Deliberately not carried over: a previous run's binaries, since inheriting them is the failure this prevents. The path is absolute because compose resolves a relative build context against the compose file's own directory rather than the working directory, which was measured rather than assumed. The chaos entry script gated the whole simulation on a binary in the shared directory by literal path, so it moves in this same commit: left behind, it would have failed on a clean checkout and, worse on a host with leftovers, passed while reading a binary that was not the one under test. Teardown removes the directory on red runs as well as green, since it holds only reproducible content and is never the evidence of a failure. The worker's SIGKILL runs no trap, so the cleanup script also sweeps contexts left by a preempted run, and the ignore rule keeps a concurrent run from showing up as untracked working-tree noise.

# No subnet is requested: docker assigns one from the daemon's address pool.
|
|
# A fixed request is honoured verbatim, so two runs asking for the same range
|
|
# collide on "Pool overlaps" — which is why the generated peer addresses are
|
|
# docker hostnames (host-a, host-b) rather than literal IPs. Docker's embedded
|
|
# DNS is per-network, so the same hostname in two concurrent runs resolves
|
|
# inside each run's own subnet.
|
|
#
|
|
# That removes one of the two obstacles to running this suite twice at once,
|
|
# not both. The compose project name is still fixed, so two runs that do not
|
|
# set COMPOSE_PROJECT_NAME share a project, and the second `up` recreates the
|
|
# first's containers while either `down` removes both. The local CI runner
|
|
# scopes it externally (run_firewall in ci-local.sh); a bare hand run does
|
|
# not. Do not read the floating subnet as making concurrent bare runs safe.
