Struct PackInstallClosure 

pub struct PackInstallClosure<'a> {
    pub pack_id: &'a str,
    pub pack_version: &'a str,
    pub pack_digest: &'a str,
    pub packages_installed: &'a [String],
    pub artifact_paths: &'a [PathBuf],
}

The witnessed closure of a pack installation.

This is the O* of A = μ(O*) for a pack install: every input capable of determining what was installed, plus the durable artifacts that resulted. emit_install_receipt binds ALL of these into the signed receipt so the receipt is a faithful proof object, not a decorative hash(pack_id).

Fields

pack_id: &'a str

Pack identifier (e.g. acme/base).

pack_version: &'a str

Resolved pack version recorded in the lockfile.

pack_digest: &'a str

Non-empty SHA-256 (hex) digest pinned in .ggen/packs.lock (integrity without the sha256- prefix). Binds the pack closure.

packages_installed: &'a [String]

Packages declared by the pack and recorded as installed.

artifact_paths: &'a [PathBuf]

Absolute paths of durable artifacts produced by the install (e.g. the install dir and the lockfile). Their contents are hashed into output_hashes.
