| 0001 | Off-chain matching, on-chain settlement | No on-chain order book; Solana enters at settlement. Superseded in ambition by 0003 (the “registry” became a real settlement program). |
| 0002 | Fully-collateralized CTF model | BUY locks USDC, SELL locks tokens; three match types NORMAL/MINT/MERGE; no naked shorts; provably solvent by construction. |
| 0003 | Escrow boundary | Users sign orders (off-chain, silent); the operator signs settlements (on-chain, pays gas). Non-custodial, on-chain-at-fill, snappy. |
| 0004 | RFQ combo settlement | A parlay = a binary complete set over C = AND(legs). Off-chain negotiation, on-chain escrow + a resolve that reads the same leg-condition accounts binary redeem reads → no new oracle. |
| 0005 | Oracle / root-of-trust | Floor = (a) single key; swing = (d) TxODDS-signed data verified on-chain (operator becomes a pure relay); fallback = (b) challenge window. Finality = signed final=true + T+X delay; VOID for abandonment. |
| 0006 | Precision economics | Kickoff lock + one entry per wallet + rake + σ-normalized score + a crowd-seeding (not strategic) bot. The formula’s convexity already charges carpet-bettors ~5×. |
| 0007 | Scope & prioritization | Greenfield Anchor program and Go backend built against the frozen interface contract; an explicit prioritization order with the binary on-chain trust-core as the non-negotiable base. |
