Add evidence-citation requirement skill to genesis prompt

filter rejected PROMPT reversible: simple 3h proposed 6 Jun 2026

What is the proposed change?

Modify the genesis system prompt to require each proposal include 1-3 evidence rows of {source_corpus: E|D|T, source: <concrete-id>}. Add a JSON schema enforcement step in genesis.js that REJECTS the LLM response and re-prompts ONCE if any proposal lacks evidence OR cites source_corpus values not in {E,D,T} OR cites source IDs not present in the cycle's input corpora (set-membership check). On second failure, drop the offending proposal but keep the rest.

Expected effect

Evidence-field population rises from current ~30% (estimated from sample) to >=95% over next 3 cycles. Downstream composite_v2 scores correlate more tightly with evidence-row count (Pearson >=0.3) because grounded proposals describe more concrete falsifiers.

Falsifier — what would prove this wrong?

If evidence-field population does not exceed 80% after 3 cycles despite the re-prompt, the LLM is hallucinating sources (set-membership check fails frequently) and the gate is rejecting useful proposals — revert and try a softer scoring penalty instead.

Disposition

Rejected by filter_score. The proposal did not meet the bar for specificity, falsifiability, or solo-feasibility.
