John Dvorak 4fd4e20bd0 js-rigor: reliability flows through every rule kind; multi_hop value collection fixed
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.

John Dvorak 2de5faa7c9 js-rigor: greybox fuzzer campaign, config validation, lifecycle positional gates
- fuzzer-mutation-needles.test.js: first greybox-fuzzer campaign (mutation
  + replay-near-failure strategies) hunting cache staleness across config
  kind transitions; pins canonical config shapes ({union:{rules}},
  {exclusion:[a,b]} with probabilistic P(A)*(1-P(B)) semantics) and a
  mirror faithful to the engine's phantom-node no-op rule
- ArbiterConfig.setRelationConfig: clean validation error for non-object
  configs (was cryptic internal TypeError under fuzzed args)
- protocol-snapshot-lifecycle.test.js: beforeStep/afterStep positional
  gates (virgin state, mirror-engine tuple sync)
- dropped complexity-verification attempt: wall-clock e-process too noisy
  at sub-ms operation scale

John Dvorak 717ae1031e initial commit: @arbiter/core authorization engine with js-rigor hardening
Zanzibar-style authorization graph engine (direct/chain/TTU/defeasible/
binary modes, condensed snapshots, value relations) with 39 rigor test
campaigns. Includes fixes for snapshot binary writer/reader format
mismatch (snapshot-of-snapshot corruption), possibility write-boundary
validation, empty-graph snapshot serialization, relation lookup cache
direction collision, config-redefinition cache invalidation, binary
threshold semantics, defeasible compiled routing, and comparator
reason whitelisting.
