Combine the schema attribute/entity, generated literal, namespace URI and mixed writer fixes from #138, #140, #141 and #142 on top of #137. This provides a validated integration branch for reviewing the changes together; the registry and attribute-guard prototypes remain separate.
Validation: full gate passes with 334 Rust tests, strict fmt/Clippy, Ruff, and 115 Python tests at 100% statement/branch coverage. Fresh CLI/native probes exercise all four fixes, including mixed nil XML→JSON→XML. Bounded CType/AttrDecl/NIST corpus summaries and failure tables are identical to the earlier candidate; six existing failing groups remain.
Three alternating benchmark pairs put ordinary catalog reads flat to 1% faster and writes about 0.6–0.7% slower versus the already-optimized #137 baseline. A short integration screen retains 29%/54% improvements for distributed 64/256-tag mixed writers; #142 holds the longer comparison and cutoff/distribution controls. Tiny sensor writes differ by about 4 ns.
Report and verified raw evidence. Main is unchanged. Keep this draft until the stacked correctness/performance changes are reviewed.
