Why: Backend main now contains the fix for the run-status write-ordering
race in Manager.ResolveHITL (PR #237, merge f084d10); the Dev repo's
modules/backend pin still pointed at the pre-fix SHA, which is why the
multi-instance acceptance test was flaky under load.
Evidence:
/tmp/repin-maketest5-20261021.json: make test green with the new pin
/tmp/repin-modules-evidence2-20261021.json: backend update + state recorded
/tmp/multi-instance-with-be-fix-20261021.json: 96-load reproduction passes (17s)
/tmp/be-runhitl-impl-r2-20261021.json: Backend transport (pi, success, 789f67f)
/tmp/be-runhitl-impl-r1-20261021.json: scope-expansion (r2 expansion granted)
/tmp/be-triage-runhitl-20261021.json: triage NEW
/tmp/multi-instance-loaded-20261021.json: red reproduction (same SHA on pre-fix)
/tmp/multi-instance-heavy-20261021.json: red reproduction under 96-load
/tmp/ci-success-testpg.log: healthy CI 22.4s measurement
Impact: a single gitlink bump (241e1b3 -> f084d10). No Dev-side source change.
Behaviour change: U7 TestTwoInstancesOverSharedPG no longer flakes under CI load.
