Code Factory 0.24.3 adds PRD Grill: a deterministic, source-bound clarification stage that asks only the next safe product decisions before PRD optimization, Product Graph compilation, or scaffolding.
It writes a capped, dependency-safe frontier, answer stubs, evidence, deferred dependencies, and a verifiable receipt. It never rewrites the PRD, invents answers, calls a model, or authorizes implementation or external effects.
See docs/PRD_GRILL.md in the release source for the full workflow and proof boundary.
