[AetherAI3]

Summary

• add BARS_SINCE, COUNT_TRUE, RISING, FALLING, and PERCENTRANK as deterministic prefix-causal kernels
• pin warmup, gap reset, period-1, strictness, tie, and prior-window semantics
• keep all calls on the existing v1 indicator node shape and Nano IR 1.0.0
• synchronize registry-derived public documentation counts to 40
• publish package 1.0.10

Evidence

• independent kernel and release-envelope reviews GREEN
• focused: 22 passed; full: 1029 passed, 2 skipped; checker: 53
• 70,997 independent oracle cases and 401,451 prefix comparisons
• six semantic mutations and five documentation-drift mutations killed
• five hash seeds stable; invalid signatures/arity rejected
• byte-identical reproducible wheel 1.0.10, registry 40, all 120 assets, catalog 53
• four golden changes are identity.nanoVersion 1.0.9 to 1.0.10 only

No grammar/checker/VM/module/IR-shape change, ambient state, execution side effect, or performance claim.
