9//! C ABI type definitions — matching upstream libxml2/libxslt (§14).
10//!
11//! This module defines all public C-compatible types with exact layout,
12//! size, and alignment matching the upstream headers.
13//!
14//! # Layout verification
15//!
16//! Every struct in this module must be verified against the oracle using
17//! `offsetof` and `sizeof` probes compiled from the upstream headers.
18//! See courts/abi-struct-*.json for verification receipts.
19//!
20//! # Phase 1 status
21//!
22//! All core types are defined. Verification against oracle is pending
23//! Docker oracle build.
24//!
25//! # Source provenance
26//!
27//! All types derived from SRC-LIBXML2-2.15.3-TREE-H and related headers.
28//! See atlas/SOURCES.md and atlas/api/ for the complete declaration inventory.
29//!
30//! # Upstream contract
31//!
32//! Mirrors the public libxml2/libxslt type surface at the 2.15.3/1.1.45 parity
33//! target: `tree.h`, `parser.h`, `xpath.h`, `xmlerror.h`, `xmlreader.h`,
34//! `xmlwriter.h`, `encoding.h` and the libxslt headers. Enum discriminants and
35//! typedef values are the contract — C consumers compile against these exact
36//! numbers.
37//!
38//! # Conceptual behavior
39//!
40//! This module implements the fundamental C-compatible types: `xmlChar` and
41//! pointers, the `xmlElementType`/`xmlAttributeType`/`xmlEntityType` node
42//! kinds, the `xmlErrorLevel`/`xmlErrorDomain` and `XML_ERR_*` error codes,
43//! parser option flags, encoding ids, buffer allocation schemes and the
44//! XML/XMLNS constant pointers. These feed every other ABI module.
45//!
46//! # Ownership & safety invariants
47//!
48//! Enum/flag types carry no ownership; the string constants are static
49//! NUL-terminated slices never freed by callers. The numeric values must stay
50//! fixed: shifting an `XML_ERR_*` constant changes every error code the parser
51//! reports to C consumers.
52//!
53//! # Historical quirks & epochs
54//!
55//! R-000163 (11.1-M): the `XML_ERR_*` constants 64-96 were a synthetic
56//! renumbered enum (e.g. SPACE_REQUIRED 89 instead of upstream 65,
57//! TAG_NOT_FINISHED 96 instead of 77) and had to be corrected to the
58//! header/upstream numbering — every error the parser emits uses them.
59//! QUIRK-0001/LORE-0001 record the 2.9.0 default parser limits epoch (commit
60//! `52d8ade7`) and LORE-0003 that `XML_PARSE_HUGE` (1<<19) existed since 2.8.0
61//! as a near-no-op before the limits made it meaningful.
62//!
63//! # Deliberate oddities
64//!
65//! The `_deprecated_*`/`_unused_*` variants and historical enum values are
66//! deliberately retained even when the current code never produces them — the
67//! numeric surface is part of the ABI. Missing-docs is allowed here for the
68//! same reason as structs.rs: the C headers are the documentation.
69//!
70//! # Proving courts
71//!
72//! The ERROR-001 differential probe (`courts/suites/data-abi/error-family-
73//! probe.c`) verifies every error code/level/message byte-identical against
74//! the oracle DSO (48/48 cases); the RUST-MIRROR-ABI court checks enum
75//! discriminants; the header-compile court compiles every public
76//! header against the candidate DSO.
77//!
78//! # Tempting simplifications that would break parity
79//!
80//! A tempting simplification is to renumber the error enums into a tidy
81//! contiguous sequence — R-000163 proved that shifts error codes silently
82//! (SPACE_REQUIRED 89 vs 65) and every C consumer matching on
83//! `XML_ERR_SPACE_REQUIRED` would misbehave. The values must match the
84//! upstream headers exactly, gaps and all.
