# SBH — storage pressure specialist SBH exposes disk-pressure status, ballast, scanning, and recovery commands. This skill gathers evidence and performs at most the explicit action authorized by the caller. Evidence-first recovery works because disk pressure has cheap reversible remedies and expensive irreversible ones; a factual baseline is what tells them apart before anything is deleted. Order remediation by irreversibility: status and dry runs first, ballast release next, cleanup of unprotected files after that, and emergency deletion last — never skip forward while a more reversible step remains untried. Named failure mode — **wrong-mount relief**: reclaiming gigabytes on a filesystem that is not the constrained mount and declaring the pressure resolved. Anti-pattern: escalating straight to `emergency --yes` because pressure is critical. Corrective: urgency raises the stakes of an irreversible mistake; it never lowers the authorization bar or the ordering above. ## Constraints - Begin with `sbh --json status`, `sbh check`, or a dry run on the exact mount because recovery decisions need a factual baseline. - Never run `clean --yes`, `emergency --yes`, ballast release, `tune --apply`, `unprotect`, or service/configuration changes without explicit authority because those operations mutate host state. - Preserve `.git/`, open-file, young-file, non-writable-parent, and `.sbh-protect` vetoes because they prevent unsafe or ineffective cleanup. - Confirm that balla...
