Systemic reliability gap found by the probe sweep: the compiled evaluation
paths never emitted the reliability the engine computes.
- Compiled _evaluateDirect omitted the relation's reliability, and the
chain/multi_hop rules hardcoded reliability: 1.0 — so check() results
reported 1.0 for any rule whose decision came through a chain, multi_hop,
union, intersection, exclusion, or defeasible combination.
- The chain and multi_hop traversals now track per-path reliability (product
of edge reliabilities) and report the winning path's value; the compiled
and fallback logical operators (union/intersection/exclusion, direct_list
fast path, early exits) report the selected child's reliability
(max/min child or OWA trace index; exclusion multiplies both legs), and
normal-mode defeasible combines base x requires x defeater reliabilities.
- The checker's logical fast path dropped collectedValues from union/
intersection/exclusion results; it now passes them through.
- MultiHopRule.valueManager was read off relationManager where the real
arbiter keeps it on the arbiter — collectValues: true on a multi_hop rule
with a value-carrying edge crashed the evaluation (error result, silent
denial). Now resolved at the arbiter level with a relationManager
fallback for stubs.
Campaign pins: reliability per kind (chain/multi_hop product, union/intersection
selected child, exclusion/defeasible product), and multi_hop value collection
through persistent and partial contexts.
Engine fixes:
- RelationUpdates.updateRelationsBatch: invalidate arbiter-level caches
(rule result cache, ChainRule caches, direct-check cache) per affected
relation — batch updates bypassed Arbiter.addRelation and served stale
decisions after batch modify/swap with warm caches
- updateRelationsBatchTransactional rollback: new Map(Set) crashed with
'Iterator value is not an entry object' — fixed to new Set
- RelationalComparatorRule: value extraction (direct-list and cached
direct paths) now gates on valueManager._isValueExpired — TTL-expired
values no longer feed comparator decisions
Campaigns:
- value-freshness-parity.test.js: batch modify/swap/tx rollback freshness
with comparator mirror (batch MODIFY of a missing relation is a silent
no-op — pinned)
- ttl-expiry-parity.test.js: injected-clock TTL expiry through the
comparator path (exact parity with caching off; bounded staleness with
caching on), faithful changed_last_at mirror semantics
