//! # ma-core
//!
//! A lean `DIDComm` service library for the ma ecosystem.
//!
//! `ma-core` provides the building blocks for ma-capable endpoints:
//!
//! - **DID documents** — create, validate, resolve, and publish `did:ma:` documents
//!   to IPFS/IPNS (via Kubo on native targets). Use [`MaExtension`] to build the
//!   `ma:` extension field, and [`config::SecretBundle::build_document`] (`config`
//!   feature) as the single entry point for a complete, signed document.
//! - **Service inboxes** — bounded, TTL-aware FIFO queues ([`Inbox`])
//!   for receiving validated messages on named protocol services.
//! - **Outbound sending** — fire-and-forget delivery of validated [`Message`] objects
//!   to remote endpoints, serialized to CBOR on the wire.
//! - **Endpoint abstraction** — the [`MaEndpoint`] trait with pluggable
//!   transport backends.
//! - **Transport parsing** — extract endpoint IDs and protocols from DID document
//!   service strings (`/iroh/<id>/<protocol>`).
//! - **Identity bootstrap** — secure secret key generation and persistence.
//!
//! ## Services
//!
//! Every endpoint must provide `/ma/inbox/0.0.1` (the default inbox).
//! Endpoints may optionally provide `ma/ipfs/0.0.1` to publish DID documents
//! on behalf of others.
//!
//! ## Feature flags
//!
//! - **`kubo`** — enables native IPFS RPC backend for publishing (native only).
//! - **`iroh`** — enables the internal iroh QUIC transport backend.
//! - **`config`** — enables [`Config`], [`SecretBundle`], and [`MaArgs`] for
//!   YAML-based daemon configuration, encrypted secret bundles, and CLI
//!   argument parsing. Also provides [`config::SecretBundle::build_document`] and
//!   [`config::SecretBundle::signing_key`] for constructing ready-to-publish DID documents.
//!
//! ## Platform support
//!
//! Core types (`Inbox`, `Service`, transport parsing, validation)
//! compile on all targets including `wasm32-unknown-unknown`.
//!
//! ### wasm vs native
//!
//! - `ma-core` supports both wasm and native targets.
//! - `IpfsGatewayResolver` (HTTP gateway DID fetch) is available on wasm and native.
//! - Native IPFS RPC write/pin APIs are native-only (`not(wasm32)` + `kubo` feature).
//! - wasm builds expose only `ipfs::gateway_resolver` (no native RPC helpers).
//! - `config` serialization and `SecretBundle` crypto work on wasm.
//! - `config` filesystem paths, CLI/env merging, and file I/O are native-only.
//! - If your wasm application needs native IPFS RPC write/pin operations, provide
//!   them in a native companion layer.
