Benjamin Admin c160bb8291 feat: Cross-Domain MCAP Convergence Analysis — which capabilities carry the system (Phase Ω pause)
After Automotive, pause on domains and ask the deeper question: not "which MCAPs occur most often?"
(frequency deceives) but "which MCAPs CARRY the largest part of the system?". A deterministic MCAP
Impact Score (no AI) aggregates over the EXISTING data only:

  Impact = distinct Sources + Target Types + Domains + Journeys + Regulatory + Business Leverage

Critically anti-frequency-deception: a `likely_covered` cap is attributed to its source CERT (one
source), not to every target regulation — otherwise generic management caps win on raw frequency.
With that fix the Core surfaces the true cross-cutting nodes: secure_signed_update_distribution (18),
technical_vulnerability_management (17), access_control, incident_management, sbom_creation,
product_cyber_risk_assessment — exactly the bridges the user predicted; the high-frequency single-
domain environmental management caps correctly drop out.

Four reports, pure aggregation (no runtime, no new architecture): Core (highest impact), Emerging
(>=2 domains), Isolated (1 source/journey — specialised or convergence-not-yet-seen), Suspicious
(too coarse: generic verbs; too fine: hyper-specific isolated names) — an abstraction-level review
tool for domain experts. 11/62 caps already reach impact >=8; the method is ready to reveal whether a
30-50 MCAP core forms as Medical/Payment arrive. Non-runtime -> no deploy. 5 tests pass, check-loc 0.
