Tools as reported by the server

• random
  Direct randomness. operation selects the primitive: bytes -- raw CSPRNG bytes. params: {count<=4096, encoding: hex|base64} int -- unbiased integers in [min,max] via rejection sampling. params: {min, max, count<=10000} shuffle -- Fisher-Yates; permutation[i] is the original index now at position i. p
• commitment
  Verifiable commit-reveal. operation selects the step: commit -- hash a seed, bind it to draw_spec {operation, params}, attest via Stamp. The seed is returned to the caller and never stored. reveal -- verify a seed against commitment_id, re-execute the draw deterministically, attest the outcome. draw
• test
  Statistical battery over a sequence: frequency, chi-squared, runs, longest run, serial correlation, Shannon entropy, KS, gap test. Informed by NIST SP 800-22; no certification claimed. sequence is a list of numbers, list of strings, or a hex/base64 byte string.
• explore
  Bandit arm selection: epsilon_greedy, thompson, or ucb1. Stateless -- caller passes state in as {arm: {pulls, successes, total_reward}} and gets a selection back. params: {epsilon} for epsilon_greedy.
