## Tools Status
| Tool | Status | Notes |
|------|--------|-------|
| `manifest.py` | ✅ Working | 183 libxml2 + 92 libxslt releases cataloged |
| `profileconfig.py` | ✅ Working | Generates xmlversion.h/xsltconfig.h for distro profile |
| `apiatlas.py` | ✅ Working | Clang-AST-based public API extractor. Fixes applied: (1) origin resolution uses loc.file/loc.includedFrom instead of buggy #line mapping, (2) XML_TREE_INTERNALS define for tree.h circular dependency, (3) system function name denylist |
| `symbols.py` | ✅ Working | ABI ground-truth comparison via readelf. Classifies SAX1 callbacks, internal __xml* functions, system leaks |
| `delta.py` | ✅ Built | Ready for multi-version API diffing |
| `court runner` | ✅ Built | Ready for differential testing (needs Docker oracle) |
## Infrastructure Status
| Component | Status | Notes |

| Court receipts | 🟡 Scaffolded | Schema and runner created, no cases executed yet |
| Historical API matrix | 🟡 Partial | Only 2.15.3 + 1.1.45 snapshots taken |
| Historical deltas | 🔴 Not started | Need at least 2 versions per project |
