The binary records only the commit it was built from -- no dirty-tree flag.
Cargo will not re-run a build script because another crate's source changed, so
a compiled-in 'clean' claim can be stale and is not a safeguard; that was
verified on the Blaze host.
scripts/verify-build-identity.sh establishes both facts at LAUNCH, where they
cannot go stale: the stamped commit equals HEAD, and the migration crates are
clean. It REFUSES rather than warns, because for a migration gate a warning on
stderr is something to scroll past.
--identity prints the stamp without valid configuration. The launcher must be
able to establish which commit a binary came from BEFORE deciding whether to
run it; requiring a correct environment first would invert the check.
redirector.sh mirrors sidecar.sh: refuses to start with an orphan present or
the port busy, matches the resolved executable rather than the command line
(pgrep -f matches any shell mentioning the name), and stop PROVES the process
is gone and the port free.

Cheap insurance, explicitly not the real check -- the semantic tests in
deployment_config.rs are what prove propagation, using two TEST-NET addresses
and bind != advertise. This grep only stops the lab subnet reappearing months
from now when the reasoning has been forgotten.
Deployment config legitimately contains real addresses and lives in gitignored
files, so it is never scanned. The frozen baseline doc is allowlisted BY PATH:
it records what a past deployment actually was, and rewriting it would falsify
the record.
Also swapped the lab IP for a TEST-NET placeholder in the usage examples and
error messages of compose/entrypoint/client_arm. Those were already correct
architecture -- every one requires the address via ${VAR:?} -- but using the
real lab IP as the example is the same 'happens to match our lab' smell, and
placeholders keep the tripwire allowlist near-empty.
Mutation-tested: adding a lab address to a source file makes it exit 1.
