  "CHKCD terminology consistently assimilated across Claude, OpenAI and Mistral.",

[interpretation.lar]
definition = "LAR aggregates signal strength, exposure, and routing maturity."
analysis = "Aggregate LAR of 63.3 (Mar 1, 2026) places CHKCD firmly in the IN_ADOPTION band. The narrow spread across models (62.78–63.96) indicates robust cross-model consistency. A slight decrease from the peak of 70+ in early Feb is consistent with natural fluctuation after the initial adoption spike."

[interpretation.cams]
definition = "CAMS measures semantic assimilation over time using prompt-external signals."
analysis = "Net acquisition averages ~6.76% across 3 model families (Claude 7.45%, OpenAI 6.31%, Mistral 6.51%). All values remain positive with CI95 lower bounds > 0, confirming statistically robust retention. The convergence across architecturally different models (Mistral vs OpenAI vs Claude) strengthens the validity of the observed signal."

[interpretation.crs]
definition = "CRS measures routing stability and temporal consistency per conceptual cluster."
analysis = "5 of 8 clusters are HIGHLY_STABLE or STABLE: meta_awareness (1.0), verification_protocols (1.0), temporal_stability (0.989), canonical_reference (0.932), multilingual_coherence (0.917). methodological_rigor (0.572) and conceptual_precision (0.542) are MODERATE. epistemic_boundaries (0.172) remains HIGHLY_UNSTABLE, consistent with adoption-phase systems managing boundary definitions."

[risks]
identified = [
  "Model updates may temporarily affect routing consistency.",
  "Increased exposure can introduce short-term behavioral dispersion.",
  "epistemic_boundaries cluster remains highly unstable and requires attention.",
  "Reduced exposure_component (0.25) in recent weeks may limit LAR growth ceiling."

[actions.recommended]
next_14_days = [
  "Increase exposure through additional CHKCD-compliant domains.",
  "Reinforce epistemic_boundaries definitions in canonical.tonl.",
  "Continue monitoring Mistral adoption trajectory (newest addition).",
  "Evaluate strategies to restore exposure_component above 0.375."
]

[conclusion]
statement = "CHKCD maintains sustained IN_ADOPTION status across 3 independent model families (Claude, OpenAI, Mistral) as of Mar 1, 2026. Cross-model convergence, positive CAMS acquisition across all models, and stable CRS for 5/8 clusters confirm that adoption is genuine and architecture-independent. The 55+ day longitudinal window validates long-term retention."
