Module structs 

C ABI struct definitions — exact upstream layout (§14, §17).

Every struct in this module is laid out to match the corresponding upstream C struct byte-for-byte on the target platform.

Upstream structs

All structs derived from SRC-LIBXML2-2.15.3-TREE-H and related headers. See the sub-agent extraction output for complete field-level archaeology.

Safety

These structs are #[repr(C)] and may be passed across the FFI boundary. Fields marked _deprecated_* or _unused_* are retained for ABI compatibility even when the upstream has deprecated them.

Phase 1 status

All core tree structs, error struct, parser context, SAX handler, XPath context/object, and I/O structs are defined.

ABI verification

Each struct must be verified with offsetof/sizeof probes compiled from upstream headers. See courts/abi-struct-*.json for receipts.
