Why: Independent re-review found an unchecked extra direct source and an unfamiliar-unit count revision. Evidence: Both counterexamples failed before Backend badf80d and passed after; prior PostgreSQL receipt belongs to 3f0141d and is preserved separately. Impact: Advance the zero-paid Backend candidate; repeat database, browser and exact-head combination validation on this SHA. Refs: Dev PR #512; Backend PR #193; r0.3 review findings
