Expand description

Action-specific filter clauses for matching document transitions.

These clauses are used to evaluate whether a given document transition (Create/Replace/Delete/Transfer/UpdatePrice/Purchase) matches a subscription filter.

Conventions:

  • Empty InternalClauses = no constraint for document-data checks.
  • Option<ValueClause> = optional scalar constraint (owner/price); None = no constraint.
  • Action-specific “at least one present” rules are enforced by validate().
