MODIFICATION_EXCLUSIONModification MOD-778 embodiedUnknown
Result:Insufficient DataUnknown is not false — see explanation below.

Why?

  • Aircraft Variant = Boeing 737-800 — expected 737-800
    Actual: 737-800
  • MSN between 35000–37000 — expected 35000–37000
    Actual: 35124
  • Engine Type = CFM56-7B — expected CFM56-7B
    Actual: CFM56-7B (SN 100781, Engine 1)
  • Component P/N = ABC-123 installed — expected Installed
    No installation record found for ABC-123 on VT-ABC. Absence is not confirmed — evidence has simply not been provided yet.
  • Modification MOD-778 embodied? — expected Not embodied
    Modification/STC tracking is not yet a structured M1 capability (see docs/ontology/M1_SCOPE.md) — absence cannot be assumed.

3 / 5 conditions resolved — unresolved conditions are shown as UNKNOWN, never silently treated as false.
