//! 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.
