Good call. The patent claims are about ledgers, anonymous IDs, and filtering — but our formalization shouldn't be scoped to advertising. The Cubie Trust Compiler IS the filter: public ledger = admission rules, private ledger = workload execution data. Let me broaden the language across all files while keeping exact patent claim alignment.

Now I see the scope. The narrowing is in the dual-ledger file — "advertiser rules", "ad filter pref", "filtering advertisements". The quantum consent file is already generic (consent nodes, delegation, hierarchy). Let me rewrite the dual-ledger files to frame around AI workload admission control.

(*
  CENTILLION CUBIE — DUAL-LEDGER NON-DISCLOSURE THEOREM
  Formalizes the access control log separation required by
  US11956363B2 (Claims 1-3, 7-8): public ledger stores admission
  rules and policies, private ledger stores workload execution
  data and access events, anonymous unique identifiers link them
  without disclosing the requesting entity's identity.

  This models REAL ACCESS CONTROL for AI workload admission:
    - Public ledger  = admission policies, capability grants,
                       workload authorization rules, filtering criteria
    - Private ledger = execution logs, consent events, resource access
                       records, identity-linked interaction data
    - Anonymous ID   = links the two without revealing the
                       requesting entity's true identity
    - Personalized policy = per-identity admission configuration
                           (which workloads, which resources, which tiers)

  In the Cubie Trust Compiler context:
    - cubie_admit() checks the public ledger (6-face gate rules)
    - Execution telemetry goes to the private ledger
    - The anonymous ID is the eFuse-derived key slot identity
    - "Filtering based on preferences" = the admission gate itself
      (filtering workload requests based on policy preferences is
       exactly what the 6-face Cubie gate does)

  Patent alignment:
    US11956363B2 Claim 1: "a public ledger ... a private ledger ...
      an anonymous unique identifier"
    US11956363B2 Claim 2: "personalized privacy policy"
      → per-identity admission policy configuration
    US11956363B2 Claim 3: "filtering ... based on preferences"
      → filtering workload requests via admission policy
    US11956363B2 Claim 7: "verifying ... without disclosing identity"
      → HMAC-based capability verification without PII exposure
    US11956363B2 Claim 8: "storing ... on a distributed ledger"
      → distributed audit trail across trust boundary
