libxml-rs 0.1.0-alpha.49

Native-Rust forensic reimplementation of libxml2+libxslt with C ABI drop-in replacement. Cross-version oracle matrix (libxml2 2.7.8-2.15.3, libxslt 1.1.26-1.1.45) with semantic epochs; full xmllint/xmlcatalog/xsltproc CLIs; differential-court-verified C API closure; three-DSO ELF packaging (libxml2.so.16 core + libxslt.so.1/libexslt.so.0 facades, upstream NEEDED chain); fail-closed oracle-isolated ABI-FUNCTION-SIGNATURE plane (SOURCE_PROTOTYPE + MACHINE_ABI fingerprints, zero silent omissions); Phase-12 real downstream substitution (binary/static/docker substitution, export-surface disposition, ELF version graphs); Phase-13 hostile audit courts (ABI/ownership/allocator/callbacks/failure/threads/oracle-contamination) byte-identical vs the system oracle incl. the upstream thread-local globals model; Phase-14 downstream custodian validation courts (lxml/Nokogiri/PHP/Debian). Test counts live in atlas/TEST_COUNTS.json, residuals in atlas/RESIDUAL_LEDGER.json (generated evidence).
