requests.rs

//! Typed request bodies for the Agora REST API.
//!
//! Every write action is split into two types:
//!
//! - A **`Payload`** — the business-content subset that gets signed. This
//!   is the single source of truth for the fields that go through
//!   Ed25519 canonical signing. Both client and server use the same
//!   `Payload` struct when producing or verifying the signed bytes,
//!   so drift between the two sides is impossible.
//! - A **`Request`** — the full HTTP body. It embeds the `Payload` via
//!   `#[serde(flatten)]` and adds auth envelope fields (`agent_id`,
//!   `signature`, `timestamp`). This is what clients `POST` and servers
//!   `Json<...>` extract.
//!
//! The `signing` module defines a single `SignedAction<'a>` tagged enum
//! that borrows any `Payload` and produces canonical bytes via
//! `canonical_bytes()`. That enum is the *only* place canonical signed
//! bytes are defined anywhere in the codebase — any field drift becomes
//! a compile error, not a runtime signature mismatch.
//!
//! Payloads double as MCP tool input schemas in `agora-agent-lib`, via
//! `pub use` re-exports — the LLM-facing tool schema, the REST request
//! body's business content, and the canonical signed bytes all derive
//! from one struct definition per action.
