 Question:
 
 > Can the public project reliably compile a bounded, versioned review-context packet from an exact committed git change without an LLM?
 
+Answer at E1: **yes, functionally**. This does not imply retrieval or reviewer-quality value.

-1. make `src/review-context.ts` exactly Prettier-compliant

+1. source candidate public review/bug-fix tasks
+2. select at least 20 tasks across at least 5 repos and 3 language ecosystems
