- watchdog: escalate forwarded SIGINT/SIGTERM/SIGHUP to SIGKILL after grace so
external cancellation can't hang for the full budget (coderabbit major)
- watchdog: route onProcExit through signalGroup for injection consistency (greptile)
- watchdog: add cwd option; test-changed passes rootDir so pnpm runs from repo
root regardless of invocation cwd (coderabbit major — preserved original run() cwd)
- dashboard runner: validate/clamp FUSION_RUN_VITEST_* env so a malformed value
can't NaN-disable the watchdog (coderabbit)
- tests: verify exit-listener cleanup, forwarded-signal escalation, cwd passthrough
- plan doc: per-class-ceiling fallback wording (not median); label Output Structure fence
