"""Cross-Domain MCAP Convergence Analysis — impact over frequency (Phase Ω pause).

Pins the deterministic MCAP Impact analysis and, critically, the anti-frequency-deception property:
a capability that bridges many target TYPES / domains / journeys (secure_signed_update_distribution)
must outrank a high-frequency single-domain management cap (conduct_internal_environmental_audits).
Four reports (Core / Emerging / Isolated / Suspicious), pure aggregation over existing data, no runtime.
