about

_sbr_install_gate.nx -- LOCK for the LM-026 ROOT FIX in nx_sov_build_run (install-on-success). NO mocks. Forks the REAL runner (_offc/nx_sov_build_run.elf) on the throwaway fixture _sbrtest and proves the runner now keeps _offc in sync with the fresh /tmp build, so gates can NEVER again fork a stale binary (the trap that cost a full session on the MMU instruction-fetch rung). RED-on-regression: if a future edit removes the auto-install or makes it pollute _offc with throwaway builds, this turns RED. T1 no-spurious : build a module with NO pre-existing _offc/<name>.elf -> NO _offc entry created (refresh-IF-PRESENT: gate/probe builds run from /tmp, must not pollute _offc) T2 auto-refresh: a STALE _offc/<name>.elf -> after build, _offc/<name>.elf byte-equals /tmp/<name>.sov.elf GREEN only if T1 && T2. Evidence -> knowledge/status/offc_install.log. license_tier: ORIGINAL
