title: Constant-regret literature update and the remaining catalogue gap
profiles:
- id: mathematical_argument
  version: 1
  required: true
claim:
  type: literature_report
  scope_statement: Reports 2026 constant external-regret claims under exact expected-vector feedback; compares their assumptions with the fixed adversarial budget and computational budget of ECON-C73-63. Does not claim to settle that catalogue target.
  assumptions: []
  limitations:
  - No full solution of the fixed adversarial-regret-budget catalogue target or its computational admissibility requirement.
  - Cited preprint theorem statements and scope checked; their complete proofs were not independently audited.
  - No claim for sampled or noisy feedback, realized-action regret, Markov games, or last-iterate Nash convergence.
