# Strategy Improvement Leaderboard
_Updated: 2026-04-07T19:01:16.706350+00:00_

_Default view excludes retired legacy PEAD / short-core / exact-pocket families, retired pre-IMP-0606 research, and incomplete train-only scans. Use `fithia2 lb --include-retired` to inspect retired research._

_`SQS` below is public SQS v9: 3-pillar additive core (RQS 35% + WFQS 40% + Regime Adaptability 25%). Regime score uses scenario-test RRS when available, falls back to OOT quality, then 50.0 neutral. OOT bias toward COVID-era performance removed. CW blend and deployment gates unchanged from v8._

## Recent Entries
### IMP-0933 (2026-04-07) — return_max_long_v7.123
Hypothesis: Re-add 3 engines removed in v7.110 (guidance_unknown+mixed_ome+other_material_unknown): 15 engines, OOT 252d median +1.63% (was -3.41%), oot_gate 0.85→1.0
Verdict: **BETTER** (SQS 66.6, Stress SQS 45.1)

### IMP-0931 (2026-04-07) — return_max_long_v7.119
Hypothesis: v7.119: 12-engine composite champion. Per-engine exit/veto optimizations + parking_v3 (entropy_max 1.45). Standalone SQS 92.4.
Verdict: **BETTER** (SQS 60.0, Stress SQS 14.5)
Reasoning: Best standalone SQS in v7 lineage. 100% WFV positive fold rate. Main RM 86.4% positive. OOT weak (2020-2021 bull-bear transition).

### IMP-0930 (2026-04-06) — return_max_long_v18.251
Hypothesis: Apply the generic mixed OME overheat cap from v19.1 (volume_ratio_max=1.0) on top of v18.250 to reduce overfit surface without giving up the stronger v18 donor stack.
Verdict: **BETTER** (SQS 64.0, Stress SQS 45.1)
Reasoning: Current-path split, merged, and WFV all improved slightly versus v18.250 while the change is a generic cap that narrows the mixed OME sleeve rather than another risk-up branch.
Next: If official public/stress also improve after reattaching current-path summaries and common-window, use v18.251 as the new SQS-improved v18 line.

### IMP-0927 (2026-04-03) — return_max_long_v19.1
Hypothesis: Tighten mixed OME orderly with a single generic volume cap to remove overheated post-market mixed reactions without widening the overfit surface.
Verdict: **BETTER** (SQS 63.4, Stress SQS 66.1)
Reasoning: Common-window and test improved while main RM and OOT RM stayed unchanged; the broader combo collapsed to the same official metrics, so the single cap is the safer expression.
Next: Only test similarly generic, cross-regime filters on sleeves that are weak in both CW and OOT; avoid exact symbol cuts.

### IMP-0915 (2026-04-02) — return_max_long_v17.72
Hypothesis: v17.60 위에 mixed/lowered/post-market earnings rebound sleeve를 독립 source로 추가한다.
Verdict: **UNKNOWN** (SQS 55.6, Stress SQS 14.2)
Reasoning: Auto-synced from official manifest.
