Execution-ready brief for the next comprehension increment (user-chosen,
doctrine-aligned): read arithmetic word-problem prose into the binding_graph
quantity substrate -> project to the independent relational_metric oracle ->
wrong=0. Reuses the existing 15-case relational_metric gold lane (no gold
authoring).
Captures the full scope from this session: the oracle grammar (fact/more_than/
fewer_than/sum_of), the new number-parsing reader capability, binding_graph
construction (SymbolBinding/BoundFact/BoundEquation with REAL admissibility — a
proof obligation, not a stamp), the direct-construction recommendation (keep the
comprehension organ disjoint from the GSM8K MathProblemGraph / serving path), the
projector, wiring, the generative round-trip anti-overfit test, and the
validation gates.
Briefed rather than rushed: this is binding_graph's first comprehension consumer,
a load-bearing integration whose correctness hinges on real equation
admissibility — it deserves fresh context, per "no shortcuts on architectural
gaps".
