//! Shared in-container filesystem-path resolution.
//!
//! Every process that runs inside an agent container - the harness plus
//! the out-of-process MCP daemons (bash, matrix, ...) - must resolve the
//! harness directory layout identically. These helpers previously had to
//! be hand-mirrored across crates (each copy carrying a "keep in sync"
//! comment) because there was no shared home for them; they live here so
//! the resolution exists exactly once.
use std::path::PathBuf;
/// Base harness directory for the current agent. Uses `HYPERHIVE_HARNESS_DIR`
/// if set (injected by the hive-c0re meta flake after the harness/state
/// split). For pre-split / dev deployments where it isn't set, falls back to
/// a `harness/` sibling of `HYPERHIVE_STATE_DIR`, and finally to
/// `/agents/{HIVE_LABEL}/harness` when neither dir env var is present — the
/// shape the harness derives from its label alone. The label tier subsumes
/// the resolver `hive-ag3nt` previously kept as its own copy, so the
/// resolution now genuinely lives here exactly once.
