…rimus price attestations Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
…ateral Replace AMM-based pricing (CSMM) with a complete-set model where users mint/burn YES+NO share pairs backed 1:1 by collateral tokens. Integrates defi-wonderland/aztec-standards Token contract for real token transfers. Adds resolution window, private ECDSA verification, and provable solvency.

…ss API
Scripts and tests now use TokenContract.deployWithOpts constructor_with_minter
instead of deploying with initial supply. Token distribution uses mint_to_private.
Auth witness creation updated to wallet.createAuthWit(account, { caller, action })
pattern with authWitnesses passed in send options.

Store Poseidon2 hash of the Primus attester's secp256k1 public key in contract storage at deployment. resolve_market now rejects attestations from unknown signers, closing the gap where any self-generated key pair could resolve the market. Switch attestation generation from proxy-TLS to MPC-TLS mode (mpctls), where client and attester collaboratively compute TLS session keys so neither party can unilaterally forge data.

Replace AMM with a private Central Limit Order Book (CLOB) for peer-to-peer limit orders with full identity privacy. Add React webapp with embedded/extension wallet support, session persistence, order book UI, and in-browser zkTLS attestation generation.

Summary
Adds a complete private prediction market example on Aztec: binary outcome markets (e.g. "Will BTC be above $50k by July 1?") with real token collateral, provable solvency, and trustless CoinGecko price resolution via Primus zkTLS attestations.
Architecture
mint_sets(n)deposits n collateral and mints n YES + n NO shares;burn_sets(n)reverses it;redeem(n)pays out winning shares 1:1 after resolution. Invariant:total_collateral = total_yes = total_noalways holds.place_orderdeposits collateral and stores a limit order publicly with maker identity hidden in an encrypted partial note;take_orderfills the order by minting a complete set and distributing YES to one party and NO to the other;cancel_orderreclaims collateral via a secret preimage (order_id = Poseidon2(cancel_secret)).defi-wonderland/aztec-standardsToken contract with auth witness flow.Privacy properties
