nocter-installation

Responsibility

Locate and validate one installed Nocter home and its compiler, manifest, standard package, and package-store compatibility.

Contract

The crate consumes explicit or process-derived installation paths and returns immutable validated installation facts. Command and workspace layers use those facts; compiler stages never inspect the environment or installation layout themselves.

Internal Responsibilities

• real executable and Nocter-home resolution
• manifest and component validation
• compiler/standard-package compatibility
• installed package-root location

Invariants

• Installation identity comes from validated content, not directory spelling alone.
• Environment and executable-path reads occur at the outer boundary.
• Invalid or mixed-version homes cannot supply a toolchain snapshot.
