# Benchmark Near-Miss Ledger

*Generated: 2026-07-16T15:52:54.806822+00:00*

Domains that pass the green gate but approach the ≤0.5% boundary — published for transparency, not hidden as post-hoc rescues.

| Gate | Value |
|------|------:|
| Green pass | 405/405 |
| Worst max scalar (any domain) | 0.4989% — `Phi_Morphogenetic_Scaling` |
| Tier-scalar max fails | 2 |
