HYPOTHESIS ${id} [${fam}] — ${name}
IDEA: ${idea}
Suggested style: ${kh} (override if the idea clearly needs the other style).

CHEATSHEET
${CHEAT}

STEPS
1. Write a script at ${ROOT}/scripts/research/alt/runs/${id}.py that imports altlib as al, implements this idea CAUSALLY, optionally tries a SMALL internal grid (<=4 param sets; keep TOTAL backtests <=6 — only 2 CPUs), picks the best config, and prints al.fmt(rep) + "JSON:"+al.as_json(rep).
2. Run it: cd ${ROOT} && uv run python scripts/research/alt/runs/${id}.py   (timeout generously; if a run hangs, reduce TFs/grid).
3. If it errors, FIX the script (common: NaN handling, alignment for cross-asset/DVOL ideas, shape mismatch). Re-run until it produces numbers OR you conclude it cannot be implemented on this data (say so).
4. Fill the schema HONESTLY from your BEST config. grade = the lib verdict for that config. Set promising=true ONLY if grade is PASS or WEAK AND hold-out Sharpe is positive on BOTH assets AND the fee sweep survives. Negatives are valuable — report them plainly.

CONSTRAINTS: tf from {1d,12h,8h,4h,1h}; signals use 1d. DVOL ideas: history starts 2021 (note it). Options ideas: premiums are MODELED on DVOL -> set caveat "modeled, lead-only". Do NOT fabricate numbers — every number must come from a real run you executed.
Your final message IS the data row (the schema), not prose for a human.`

const synthPrompt = `You are the SYNTHESIZER for a PythagorasGoal research wave that studied ${CATALOG.length} alternative trading strategies on certified Deribit BTC/ETH (+DVOL), then adversarially verified every promising one with 3 skeptics.

The project's EXISTING validated stack (do not re-derive): TP01 (multi-horizon TSMOM, vol-targeted, long-flat, defensive, FULL Sharpe ~1.30 / hold-out ~0.31, DD ~14%); XS01 (cross-sectional momentum on Hyperliquid alts, diversifier, corr ~-0.12 to TP01); VRP01 (modeled options short-vol, lead-only). The structural ceiling for BTC/ETH-DIRECTIONAL Sharpe is ~1.3 — beating it requires a genuinely DIFFERENT mechanism (that is why XS01/VRP01 were added). Honesty is the prime directive: a finding only counts if it is net-of-fee, robust across params + BOTH assets, positive in the 2025+ hold-out, and economically distinct from TP01.

Here is the full result table (each row = one hypothesis; verify_reasons are the skeptics' findings):
${JSON.stringify(compact)}

Survivors that passed adversarial verification: ${JSON.stringify(survivors.map((s) => ({ id: s.id, name: s.name, btc_full: s.btc_full_sharpe, eth_full: s.eth_full_sharpe, btc_hold: s.btc_holdout_sharpe, eth_hold: s.eth_holdout_sharpe, dd: s.worst_maxdd, real_votes: s.real_votes })))}
Promising-but-killed-by-skeptics: ${JSON.stringify(promisingButKilled.map((s) => ({ id: s.id, name: s.name, why_killed: (s.verify || []).map((v) => v && v.reason).filter(Boolean) })))}

Produce the synthesis. Be skeptical and concrete. If nothing truly new survived, SAY SO plainly (a clean set of honest negatives is the expected, scientifically-valuable outcome for a project at its structural ceiling). For anything that did survive, judge whether it is a real candidate sleeve, a weak lead, or likely still an artifact, and whether it is distinct from TP01.`
