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.

For the v0.2.0 release-candidate lane, parser authors should treat this as the Rust package for GroundingSource implementations:

ethos-doc-core = { version = "0.2", features = ["grounding"] }

use ethos_core::grounding::*;

The package name and import name intentionally differ. The package is ethos-doc-core; the Rust library crate is ethos_core.

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.
• v0.2.0 registry install wording remains in release-candidate status until publication, registry availability, and clean smoke tests are recorded.
