Raw Blame History

//! The capability seam: five adapters implementing `tinyflows::caps` traits
//! over real OpenHuman services.
//!
//! Each tinyflows integration node hands its **whole** `node.config` to the
//! matching trait method — the adapter interprets a free-form JSON value the
//! flow author wrote, pulling a connection ref out of `config["connection_ref"]`
//! where relevant. See `my_docs/ohxtf/b1-engine-seam-domain/04-capability-seam.md`
//! for the source-verified node → trait contract this mirrors.
//!
//! All host errors are mapped to `tinyflows::error::EngineError::Capability`,
//! per the crate's contract (`caps` traits return `tinyflows::error::Result`).
