[0.3.43] - 2026-05-03

Cross-binding parity, WASI build target, and a basket of issue fixes.

Highlights

• render_page_fit() now ships in all five bindings (Rust core + Python, Node.js / TypeScript, C#, Go). Picks the largest DPI such that both rendered dimensions fit inside a target pixel box, preserving aspect ratio. No more "what DPI hits 1024×768?" math on the caller's side. Fixes #441, closes #448.
• Idiomatic page iteration parity across bindings. Rust gets page_indices(), Python gets .pages, Node.js gets [Symbol.asyncIterator] (the sync [Symbol.iterator] was already there). C# Pages and Go Pages() were already shipped. Closes #447.
• WASI build target — cargo build --target wasm32-wasip1 now builds the lib cleanly on stable Rust. Unblocks @​RALaBarge's external pdf-oxide-wasi stdin→stdout wrapper and any other consumer wanting to embed pdf_oxide in a sandboxed WASI runtime. CI now gates that the WASI build stays green. Closes #214.
• Spurious-table fix on dense word grids — Roland's #405 lands via cherry-pick. A new has_split_modal_column_groups validator inspects the column co-occurrence graph across modal rows and rejects candidates whose populated columns split into two or more disconnected components — the signature of two adjacent text flows mis-clustered as one table. Composes cleanly with v0.3.42's Table::is_real_grid filter. Validated against the 86-PDF cross-build corpus: 888 / 888 byte-equal — zero observable change on common documents, the gate's value is in the safety net for adversarial cases.

Fixes

• #456 — PdfDocument::open(path) now populates source_bytes, unblocking convert_to_pdf_a(), the C FFI pdf_document_get_source_bytes, and any other API that re-reads the in-memory copy. Path-loaded documents previously got an empty Vec<u8> and hit "Invalid PDF header: File is empty (0 bytes read)" from the PDF/A converter. Reported by @​potatochipcoconut on PR #445.
• #451 — Standard14 PostScript fonts with no open-source equivalent (Symbol, ZapfDingbats) are now downgraded from hard FontNotEmbedded errors to a new KnownUnembeddableFont warning during PDF/A conversion. A document that's otherwise compliant no longer fails solely because of one symbolic font.
• #395 — closed; verified the off-by-one C# ExceptionMapper fix in v0.3.38 actually resolves the reported RenderPage → SignatureException [8500]. Added a Rust regression test that
