  "changes": "Moved checkout before all eight original floor sites (CI: changes, unit Windows/Linux, lint, traceability; release: build Windows/Linux, assemble), preserving changes.fetch-depth=2. Added per-site IR-73 placement explanations and IR-46/IR-59 instantaneous-floor comments; removed release headroom claim. All eight starts emit FLOOR_START; eight new end arms emit FLOOR_END after final workloads with always() guards and native shells. DISK-prefixed names, fresh raw-byte measurements, 32 GiB threshold, and strict free<floor rejection retained.",
  "validation": "Not run, as explicitly assigned; Main owns final validation. No commits or unrelated edits."
