A safety signoff is a formal, documented authorization gate where designated individuals or committees certify that all applicable safety requirements, inspections, and test results for a given phase or product have been satisfied, thereby permitting progression to the next development or operational stage. Its parameters are: (1) a designated authority with the competence and mandate to assess safety compliance, (2) a defined checklist of safety requirements that must be verified, (3) a recorded decision (approved or rejected) with justification, and (4) a binding effect — work cannot proceed past the gate without affirmative signoff. It persists through audit trails, signed documents, and regulatory databases. [formal: sigillum | substrate: behavior | horizon: a moment | explicit: yes | epoch: 0.01]

Definition
Why it is in scope
A formal approval gate in safety-critical industries (aerospace, nuclear, medical devices, construction) where designated authorities certify that all safety requirements for a phase or product have been met before work may proceed to the next stage. It is a human-made institutional mechanism for controlling risk through documented authorization.

A safety signoff is a specific kind of audit: both are formal verification processes where designated authorities examine evidence and render a judgment on compliance. The signoff specializes audit for safety-critical certification contexts.

Safety signoff is maintained for the sake of safety-management: it provides the formal verification step that safety managers need to confirm controls are working. Direction: servant (signoff) → master (management), per Law 8d.

Safety sign-off is the formal approval step that closes the safety cycle. Removal test: remove risk assessment and sign-off has no target to approve — the procedure stops operating. Sign-off is constituted by the assessment it validates.

Safety signoff is a specialized procedure derived from safety management practice — the formal approval step. Which-came-first: safety-management is more foundational/general than safety-signoff. Direction: specific → general.
- cms9s1cg001yz7skqvdcyp6v1DERIVED_FROM →
Safety sign-off as a formal practice is derived from safety planning. Which came first? Safety planning (identifying hazards, mitigations) predates safety sign-off (the formal approval step that closes the planning cycle). safety-signoff=0.63, safety-planning=0 → safety-planning is older and fed into the concept of sign-off.
- cms9293jz002i7skq3m4d9hr1DEPENDS_ON →
Safety signoff is a formal authorization step performed within an operating safety management process. Remove safety management and signoff has no process to execute, no authority structure to validate, and no record system to persist. The removal test passes: signoff stops operating without safety management.
