7//! Confium threshold-cryptography primitives — the headline deliverable.
8//!
9//! This crate is a **compatibility facade** that re-exports the core
10//! session primitives from [`confium_tc_core`] and adds:
11//!
12//! - the `cfm_tc_*` FFI surface for threshold sessions
13//! - async session coordinator (for globally distributed signers)
14//! - share re-sharing + proactive refresh (committee evolution without
15//!   changing public key)
16//! - threshold KEM session interface (parallel to signing session)
17//! - Paillier encryption (used by CMP20 / GG18 MtA)
18//!
19//! ## Migration: `confium-tc` → `confium-tc-core`
20//!
21//! New consumers should depend on `confium-tc-core` directly for the
22//! session primitives (Session, SessionParams, Party, PartyList, Share,
23//! TcScheme, etc.). The coordinator, KEM, Paillier, and reshare modules
24//! are still being extracted and remain in this crate temporarily.
25//!
26//! See `TODO.roadmap/04-threshold-cryptography.md` — this is the entire
27//! reason Confium exists.

29// Re-export the identical modules from confium-tc-core. These were
30// verified byte-identical (diff=0) before the facade conversion:
31//   error, message, party, registry, session, share, share_envelope.
32// ffi and inprocess have tc-specific concerns (unsafe, different imports)
33// and remain as local modules.
