methodologies/composition-aerospace-flight-control overview

DO-178C flight-control software composition (backlog Example 6): Waterfall system/software requirements capture -> V-Model decomposition with per-level verification plans -> Cleanroom incremental development with statistical usage testing -> INLINE formal verification of critical properties (parallel per-property proofs with EXECUTED proof-checker output) -> certification evidence assembly with an independent adversarial certification gate -> flight-software baseline release. Every stage exit is guarded by an EXECUTED requirement-to-verification traceability gate plus a routed verification-lead sign-off; safety-requirement waivers, DER certification sign-off, and baseline release are policy-gated, fail-closed human approvals that never auto-execute. Pairs with composition-regulated-greenfield to complete the safety/compliance quadrant. The formal-verification ingredient is modeled INLINE as caf.* tasks per the batch-3 strangler-fig precedent (composition-legacy-modernization) because no library/methodologies/formal-verification/ dir exists.
