Extends the complex-graph suite to the remaining uncovered surfaces:
- complex-graph-ttl-crucible: value-TTL expiry over community/scale-free
graphs (pinned changed_last_at writes, {now} reads, mirror freshness
rule), mutation-with-time binary parity, snapshot round-trip preserves
the TTL gate. Notable find: snapshot restore resets changed_last_at to
access time (RelationSnapshotAccess.js:91), so TTL assertions compare
each engine against its own effective write clock.
- complex-graph-overlay-crucible: partial-graph overlay over complex
graphs. Key discovery: pre-built PartialGraphContext must be passed as
partialGraphContext (partialGraph is a raw spec re-ingested at
ArbiterChecks.js:15); overlay rides the direct relations a policy
consumes (TTU-derived can_read ignores it, verified by probe).
- complex-graph-values-crucible: relational-comparator over value-carrying
relations with pinned clocks — comparator parity, value-mutation flips
the decision immediately, TTL expiry on the comparator denies.
- complex-graph-reachability-crucible: PLTC reachability vs ground-truth
BFS on scale-free/community graphs — verdict parity, fast-fail
soundness (no false positives), null-defer contract honored.
- complex-graph-batch-crucible: addRelationsBatch vs sequential build
parity, mutation parity across both, cache-freshness after mutation.
- complex-graph-quantization-crucible: 16-bit quantization band over real
possibility spreads, allow/deny agreement outside the band, snapshot-of-
snapshot semantic identity.
Also seeds the two unseeded campaigns in tuple-to-userset-rule.test.js
(flagged flake ~1/15 — nondeterministic runs on a deterministic engine).
Rigor 245/245, full suite 847/785/0.
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.
