jedarden	4ba4687a36	feat(pdftract-36glh): implement JPXDecode passthrough with JP2 validation ... Implements JPEG2000 (JPX) passthrough filter per Phase 1.5: - JP2 box magic validation (12-byte signature check) - STREAM_INVALID_JPX diagnostic for raw J2K/corrupt data - OCR_JPX_UNSUPPORTED diagnostic when full-render+libopenjp2 unavailable - Runtime libopenjp2 detection (pkg-config + ldconfig fallback) - Passthrough behavior (raw bytes unchanged) Module: crates/pdftract-core/src/decoder/jpx.rs Stream integration: JpxStreamDecoder in parser/stream.rs Acceptance criteria: - JP2-wrapped JPX with full-render → passthrough, no diagnostic - JP2-wrapped JPX without full-render → OCR_JPX_UNSUPPORTED - Raw J2K codestream → STREAM_INVALID_JPX + passthrough - Round-trip test coverage (unit tests validate JP2 signature) Per plan EC-12: emits diagnostic when neither full-render nor libopenjp2 is available, alerting Phase 5.2 OCR pipeline.

jedarden	b8a1b8f193	fix(pdftract-2sswr): add Default impl for PageDict to fix JBIG2 compilation ... This commit fixes a compilation error in the javascript tests that were using PageDict::default(). The JBIG2 decoder module was already fully implemented; this change only enables the tests to compile and run. Changes: - Add Default impl for PageDict in parser/pages.rs - Verify all 11 JBIG2-related tests pass The JBIG2Decode passthrough filter implementation is complete: - Passthrough of raw JBIG2 bytes - /JBIG2Globals reference recording for downstream consumers - OCR_JBIG2_UNSUPPORTED diagnostic emission when full-render disabled Co-Authored-By: Claude Code <noreply@anthropic.com>	2026-05-28 04:44:45 -04:00
