btctax_cli/
lib.rs

1//! btctax-cli: the CLI + reconciliation library that wires the encrypted vault (btctax-store),
2//! ingest (btctax-adapters), and the pure projection (btctax-core) into the Phase-1 command surface
3//! (spec §11). The library is I/O-explicit and deterministic; the binary (`main.rs`) is a thin clap
4//! dispatch. PRIVACY: tests use only temp vaults + synthetic fixtures; no real user file is ever read.
