Probe sweep of the OWA surfaces found three real defects:
- reliabilityWeighting was a silent no-op everywhere: every implementation
scaled possibilities by metas[i].reliability, but no child meta ever
carried a reliability field (the compiled direct omitted it and the
DirectRule handler omitted it too), so the weighting was always x1.0.
All weighting branches now use the tracked child reliabilities, and the
DirectRule handler + its meta now carry the relation's reliability.
- The compiled union and the direct_list fast path had no
reliabilityWeighting branch at all; both now apply it.
- Shorthand children ({ relation: 'editor' }) dispatch to the direct
handler but carry no type, so _getRuleResultCacheKey derived the generic
'rule' suffix for every shorthand child of a logical rule — the first
child's cached result was served for all of them (the fallback path
returned the owner's 0.8 for the editor). The key derivation now matches
the shorthand dispatch. The RuleEvaluator also treats shorthand operands
as direct rules instead of unknown_rule_type on the non-compiled path.
New pins: an OWA differential property (custom weights, max/min/average
aggregators, reliabilityWeighting, compiled path) and a multi_hop
pathAggregation=owa fixed pin with reliability propagation.
