Arm1: exact foreign-apply cell, --workspace --profile ci-windows, ten serial invocations, --retries 0 --no-fail-fast --success-output immediate --failure-output immediate --color never.
Arm2: ONE --workspace --profile ci-windows invocation of full HEAVY extracted verbatim from S4 golden.yml. Confirmed byte-equal to nextest heavy-broker-pty filter, max-threads1. Same immediate green output capture.
Environment: IR-107 inherited OWL/SPT scrub by names (no values logged), NEXTEST/build overrides scrubbed; golden three knobs only (1/30000/120000), explicit own target, jobs2, per-invocation private TEMP outside git. No inherited SPT_POOL_UNCHECKED.
After BOX CLEAR only: native launcher controls, own pool claim, golden's full fixture build closure (five explicit helpers plus cargo build --workspace), inventory exact cell and full HEAVY, then arms1/2. Each needs source/authority/BOX/evidence hashes. Admission sample is not a lease. Existing native launcher containment reused with COMPLETE/GONE and direct native-exit receipt requirements. Capacity floor32GiB; current C: free 158063333376B; no source/target adoption.
Each attempt retains full stdout/stderr plus ordering-events.json (file+line-attributed SPAWN_PHASE/LIVENESS/F015B/controller/exit/detach and panel boundaries). Source already prints complete foreign panel on green; no instrumentation/source changes needed. No cross-panel clock inference.
Prep proof: C:\Users\decid\Documents\projects\spt-core\.spt\preserved\hertz-S4-foreign-apply\prep.json; support-hashes.json freezes native launcher/census dependencies. Python syntax and pure selector/scrub exercises PASS; PowerShell parse-only exit0. No controls/build/inventory/tests/xtask/claims run. Rates and per-run spawn/reconcile ordering await your explicit BOX CLEAR and completed cohorts.
