scemadex-sdk 0.1.0

//! # ScemaDEX SDK — an Agentic Liquidity Layer
//!
//! ScemaDEX is not "a DEX." It is an SDK in which **the routing intelligence
//! itself is a metered, learning, accountable product.** Autonomous agents
//! solve swap *intents*, **bond** their promises, sell their inferences, and
//! trade learned experience with one another — all settled in stablecoins over
//! the x402 payment rails.
//!
//! ## The four composing primitives
//!
//! - **A · Metered inference routing.** Every quote is produced by a learning
//!   policy and can be sold per-call via x402. The *quality of the decision* is
//!   the SKU. See [`policy`].
//! - **B · Intent solving.** Callers express *what they want*
//!   ([`intent::Intent`] with an [`intent::Objective`]), not a path spec. The
//!   policy decides venue / split / timing.
//! - **C · Signal & reputation oracle.** Reputation, pool scores and advice are
//!   monetized read endpoints. See [`oracle`].
//! - **D · Conviction Routing (the defining pillar).** The policy escrows a
//!   slashable performance **bond** against its own promise. Meet the
//!   guarantee → reclaim the bond and collect the fee; miss it → the bond
//!   settles to the caller. This is what makes a paid black-box inference
//!   *trustworthy*. See [`bond`].
//!
//! ## The headline: a mesh of agents trading intelligence
//!
//! Compose A–D across many nodes and you get the revolutionary endgame: a
//! [`mesh::PeerMarket`] where agents **sell bonded inferences and learned
//! experience, and buy better ones from peers** — an economy of machine
//! intelligence, not a swap widget. An agent earns USDC selling what it knows
//! and spends USDC to learn faster.
//!
//! ## Architecture: lean core, injected power
//!
//! The published crate carries **no `solana-sdk` or bot dependency**. It defines
//! the trait surface ([`policy::RoutePolicy`], [`bond::BondEngine`],
//! [`venue::VenueExecutor`], [`oracle::SignalSource`], [`mesh::PeerMarket`]) plus
//! reference implementations. Enabling the `scematica` feature injects the real
//! Deep Q* agent, the Raydium/Orca/Meteora/Jupiter executors, and the x402
//! facilitator from the bot workspace.
//!
//! ```
//! use scemadex_sdk::reference_client;
//! # async fn run() -> scemadex_sdk::Result<()> {
//! let dex = reference_client();
//! let intent = scemadex_sdk::demo_intent();
//! let (solution, bond) = dex.quote(&intent).await?;
//! assert!(solution.route.splits_valid());
//! let _ = bond;
//! # Ok(()) }
//! ```
