//! 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 live here so the
//! resolution exists in exactly one place rather than being mirrored
//! across crates.
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.
