ethos-pdf

ethos-pdf is the in-tree Rust crate for the PDFium-backed PDF source path behind Ethos parser traits. It normalizes parser output before data crosses the crate boundary.

ADR-0006 reserves the public crates.io identifier ethos-pdf at 0.0.0-reserved.0.

For the v0.2.0 release-candidate lane, this crate is a continuity crate for the lockstep Rust workspace. The release headline remains JSON verification and evidence anchoring over caller-provided source evidence. ethos-pdf remains the parser/PDFium-facing crate.

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

PDFium Boundary

• No PDFium binary is bundled in this crate.
• PDFium remains caller-provided through ETHOS_PDFIUM_LIBRARY_PATH.
• If ETHOS_PDFIUM_LIBRARY_PATH is missing, PDFium-backed paths fail with a setup error naming the environment variable.
• Public schemas and APIs expose no PDFium types.
• v0.2.0's no-PDFium claim applies to JSON verify and evidence-anchor workflows. Parser, crop, and render paths may still require caller-provided PDFium.
• If that boundary cannot be guaranteed in a later review, ethos-pdf remains held out of any future crate surface.
