Understanding Categorical Signal Share
The proportion of an entity's total accumulated stock signal (S_stock) composed of categorical signals. Formally: κ_cat_share = S_cat / S_stock ∈ [0,1]. Entities with higher κ_cat_share are structurally more resilient at competitive saturation because their stock advantage does not erode with competitive adoption m. Two entities with identical total EAS scores may have very different competitive durability depending on their κ_cat_share composition.

Frequently Asked Questions
What is Categorical Signal Share?
Categorical Signal Share (κ_cat_share) is the proportion of an entity's total accumulated stock signal (S_stock) composed of categorical signals, formally κ_cat_share = S_cat / S_stock ∈ [0,1]. It measures structural resilience: how much of an entity's authority advantage survives competitive saturation.
Why can two entities with identical EAS scores have different durability?
Because EAS is a snapshot measure that does not distinguish categorical from probabilistic signal composition. Two entities scoring identically on EAS may have very different κ_cat_share values, meaning one retains full advantage at competitive saturation while the other's advantage collapses as competitors invest equally.
How is Categorical Signal Share improved?
By converting probabilistic signal investments into categorical signal infrastructure: establishing authority database records, institutional registry memberships, vocabulary declarations with timestamp attribution, and cross-registry identity networks that AI systems treat as ground truth rather than probabilistic evidence.
