- pdf-graphics: new cff, truetype, cjk_cmap, disk_cache, document_ai, path, reflow, text_diff modules + port tests (all green); syntax/type fixes for the aarch64 build (stray brace, &u8 derefs, f2dot14 assign). - pdf-document: ocr, pdf_a, xmp modules + roundtrip tests; annotation editor updates. - pdf-makepad: handle RenderCommand::SetOverprint (report via TransparencyError per ADR 0009, no silent drop); renderer/page_view updates for the new recording ops. - matrix_client: nimanyatta native module (ungated; the aarch64 wrapper needs it unconditionally). - pageflipnav home_screen: project_store sync is host-only until cad-ui's Widget Script derive is fixed for aarch64. Verified: cargo check on all four crates clean at fork 66cc4f15f; nigig-pdf-graphics tests pass; pageflipnav aarch64 release links.

//! Phase 9 exit criterion: XMP metadata round-trip through a real document.
|
|
//!
|
|
//! The unit tests in `xmp.rs` parse hand-built packets. These go through the
|
|
//! whole write→parse pipeline: a document is built with an XMP packet in its
|
|
//! catalogue `/Metadata` stream, written, re-parsed, and the metadata is read
|
|
//! back off the catalogue — proving the `read_xmp` path navigates the real
|
|
//! trailer→catalog→stream→decode chain, not just the parser.
|
|
//!
|
|
//! See `REVIEWS/adr/0039-pdf-xmp-and-conformance-decisions.md`.
