Struct ContentHash 

pub struct ContentHash(/* private fields */);

A SHA-256 package version identity.

Legacy identities cover each module’s logical name and exact .beam bytes in BeamSet canonical order. Explicit-timeout identities append a domain-separated timeout encoding. Archive representation and optional source inclusion never participate, so deterministic inputs keep one version.

“Source inclusion” is EVERY archived-source family, and this is a declared non-property rather than an accident of the current encoding: neither the Gleam src/ entries nor the AWL awl/document/ + awl/schema/ entries (see crate::awl) contribute a byte to any identity above. Two packages that differ ONLY in whether they carry an authored AWL document, or in what that document says, are the SAME version — the provenance an archive shows is declared unbound from identity, never ambiently assumed to be bound. Pinned by source_inclusion_does_not_change_manifest_version and awl_source_inclusion_does_not_change_manifest_version in crate::builder.

Its stable textual form is 64 lowercase hexadecimal characters. That text is the package version identifier stored in the manifest and the hash component embedded in namespaced deployed module names; it contains only 0-9a-f, which is safe for a BEAM module-name component.
