# ethos-doc-core
`ethos-doc-core` is the in-tree Rust package for Ethos document evidence contracts: canonical document
types, deterministic serialization identifiers, fingerprints, stable codes, schema types, and
trait boundaries.
ADR-0006 reserves the public crates.io identifier `ethos-doc-core` at
`0.0.0-reserved.0`. The Rust library name remains `ethos_core` so existing source imports keep the
same crate path while registry action remains blocked.
## Publication Boundary
- Publication metadata is activated for the approved crates.io candidate surface.
- Public installation from crates.io remains blocked until refreshed tag/source binding and
operator evidence are recorded.
- The reserved crates.io placeholder remains `0.0.0-reserved.0` until registry action is
explicitly recorded.
- This README supports package-publication activation review only.
- Source-only pre-alpha crop descriptor APIs are not part of the default public surface. They
require the explicit Cargo feature `crop-element`, which exists for in-tree CLI contract work.
