v0.5.435-rete-plus-develop: β-A skip counters + measurement Builds on v0.5.434 with one telemetry change: - 7c308399b perf(rete): β-A skip counters + benchmark output of gate effectiveness Adds two SelectiveEvaluator counters (total_relational_alpha_skips_- disjoint, total_relational_alpha_skips_source_type) so we can see how much the β-A watched-property gate and the source-type filter actually save on real recipes. Surfaced via get_rete_stats() and printed in the two_origins benchmark output as a "gate effectiveness" ratio. Initial measurement (local, two_origins): Relational alpha evals: 21,068 Rel. skips (disjoint): 4,304 Rel. skips (src-type): 483 Rel. gate effectiveness: 18.5% This closes the β-A measurement question (Phase 2 ship-or-revert decision = SHIP, already shipped via aca0c576a / 5ad7d4a57 / the network_builder.relational_alpha_watched wiring; just wasn't visible in stats output until now). Tasks #128 (alpha-by-node-type index) and #185 (cluster 2.4x gap) also closed in this turn — superseded by the measurement here and the cluster-noise finding respectively.
