NEXO Brain v7.30.9

Release 7.30.9 makes the runtime doctor and release gate distinguish real installed-product failures from stale operator/session history. It also stamps a verified post-update repair baseline so old Codex transcripts and protocol drift do not keep a repaired install red, while live hook/config failures still block.\n\nValidation: release readiness OK with 239 pytest checks, focal tests 149 passed, npm root dry-run OK, OpenClaw build/test/pack dry-run OK.
