- DSLValueGraph integrates the evidence DSL with @arbiter/value-graph: measures
become typed value-graph nodes; attach() wires runtime.measure through the graph.
- DSLRuntime.check() now retrieves required MEASURE values and injects them as
value-carrying self-edges, so an evidence comparator over a measure (e.g.
budget_used(user) <= budget_limit(user)) evaluates — measure and evidence
compose (provider-sourced AND value-graph-sourced), with 3 new composition tests.
- BUILTIN_TYPES: bigint → buffer (the value-graph wire is JSON-free/bigint-free).
- @arbiter/value-graph: file:../value-graph → ^0.1.0 (registry); CI auth adds
@push-stream-std registry for the transitive dep.
- rigor core ^3.1.2 / probe ^0.0.8.
An evidence may now reference another derived evidence as a sub-rule
(WHEN can_read(user, doc) where can_read is itself an evidence). Resolution
is a compile-time linker pass: after every evidence config is generated, each
direct reference to an evidence is inlined with that evidence's own (resolved)
config, so the engine evaluates a fully-resolved, acyclic config tree.
- resolveEvidenceReferences(): post-generation pass over evidence configs,
recursing into logical/defeasible containers (when/unless/never/always/
requires/union/intersection), always.direct nests, and comparator operands.
- Forward references resolve (all configs exist before the pass runs).
- Cycles and self-references are compile-time errors.
- _subjectAsObject scoping is preserved through inlining.
- dependsOn is recomputed after resolution, so partial-graph requirements
reach transitively through composed evidence.
- buildDirectRule/buildPredicateRule now apply subject-scoping to top-level
PredicateCall evidence bodies (latent gap, previously missed).
- validation: reject relation names shared across facts/sources/evidence/
measures (a collision silently overwrote configs and read as a false cycle).
Tests: EvidenceComposition (9), DSLRuntime transitive requiredFacts, oracle
campaign composition construct, illegal-mutations cycle + cross-kind cases.
