Human ruling on the needs-human-review allocator swap (+4.6%, CI
[+3.3%,+5.8%]): accepted as a real win for the measured comrak CLI
single-stream markdown-render workload, explicitly not a blanket
mimalloc mandate. Ledger row stays needs-human-review (append-only);
the ruling is documented in results/rulings/phase0-comrak-002.md and
reflected in the case study.

phase3-cjson-002 (class 5+3): stack-buffer number parsing + strtod
round-trip replacing sscanf. +8.85% median, 95% CI [+7.5%, +10.0%] on
the C target, banked. 100% audit: byte-identical golden replay,
independent ASan+UBSan clean, 10k-input differential fuzz 0 divergences,
patch bounds/free-gating verified by eye.
- verdict: an infrastructure sanitizer-BUILD failure (missing runtime,
broken toolchain) now caps the accept at needs-human-review and logs
it, instead of crashing the verdict and losing a measured bench.
- results/phase3/: four public case studies (tokei class-5 wins; build
flags + allocators; the comrak caught false-accept; the cJSON
cross-language proof) + README. Compound-speedup claim stated as an
approximation, not a measured figure (CIs don't multiply).
- .gitignore: cjson build-artifact dirs.
