rule_timing.csv intentionally omitted (Jena native per-rule timing fallback).

Per-rule wall-clock timing is not exposed by Jena's GenericRuleReasoner (FORWARD_RETE) without Java-side instrumentation. Per Phase 2 Spec v1.8 §10.5, rule_timing.csv is intentionally omitted under this fallback rather than emitted with rule_eval_ms=0 on every row (which would be a Jena-limitation marker, not a measurement). The lumped subprocess time appears in outcomes.csv jena_inference_ms / total_eval_ms, and this limitation is also recorded in batch_manifest.timing_fallback_note.
