Implement orchestration layer connecting HttpRangeSource to Phase 1.3 xref resolver and Phase 1.4 document model for remote PDF access: - Document::open_remote() public API for remote PDF loading - Progressive tail fetch (16 KB → 1 MB) for startxref location - Xref forward-scan disabled for remote sources (via is_remote check) - Page-by-page on-demand fetch via HttpRangeSource caching - Resource lazy load through XrefResolver cache - HEAD probe with 405 fallback, no Content-Length handling Acceptance criteria: ✅ open_remote(url) returns Document with correct page count ✅ HEAD failure modes (405, no Content-Length, 401) handled ✅ xref forward-scan disabled for remote (is_remote check) ✅ Page-by-page on-demand fetch (HttpRangeSource LRU cache) ✅ INV-8 maintained (all errors return Result) Files modified: - crates/pdftract-core/src/document.rs (Document::open_remote, from_source) - crates/pdftract-core/src/remote.rs (progressive tail fetch) - crates/pdftract-core/src/lib.rs (re-exports) Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> |
