Methodology IP
S/PF/F split is non-negotiable methodology. Partial failures are NOT collapsed into failures. A partial (e.g. payload delivered to wrong orbit, booster lost on otherwise-successful flight) is treated as a distinct outcome for underwriting. See /methodology/.

METHODOLOGY
Per-vehicle reliability is aggregated from the AstraVeris launch_events table with Wilson 95% lower-bound error estimates. Subsystem outcomes are extracted by a local Gemma model from primary-source articles — outcomes are never fabricated; absence of a row means "not tracked". Aspirational vehicles (not yet flown) carry registry-only metadata with explicit "Not yet flown" banners. Full specifications: /methodology/. Licensing terms: /data-licensing/.
Not investment advice. For insurance underwriting, verify against operator investigation reports.
