+
+### Read (relative only)
+
+1. **Same strategy, broader liquid universe kills the book** (A→B and C→D).
+   Sharpe collapses; DD roughly triples; win rate drops ~6–8pp; trade count
+   ~doubles. This matches earlier breadth IC work: the production residual +
+   high-vol package is a **large-cap / prod-universe** edge, not a
+   “more names = better” edge.
+
+2. **Longer history on 505 stays positive but softer** (A→C). Sharpe 1.32 → 0.88,
+   CAGR 32% → 17%, DD 19% → 24%. Still well above the liquid-breadth arms.
+   Levels are optimistic (survivorship); the useful message is “edge does not
+   vanish when 2018/2020 are included,” not “expect 17% CAGR forever.”
+
+3. **Arm A vs older Phase‑A / short-window controls** (~Sharpe 1.7–2.1): this
+   matrix re-ranked on deep research.sqlite with a fixed entry start; numbers
+   need not match prior reports row-for-row. Use **this table for A–D
+   comparisons**, not for rewriting the production baseline number.
+
+4. **No production change implied.** Keep the live ~505 universe. Do not broaden
+   the tradable set to liquid Nasdaq under current knobs without a new
+   pre-registered design (and almost certainly a different rank/tilt package).
 
 ## Verdict
 
-**PENDING_HUMAN** after numbers land.
+**Descriptive matrix complete.**
+
+| question | answer from this matrix |
+|---|---|
+| Prod book @ ~4y / 505 | Positive (arm A) |
+| Same + liquid Nasdaq | **No** — large degradation (arm B) |
+| Prod book since 2016 / 505 | Still positive, milder (arm C) |
+| Same + liquid Nasdaq deep | **No** — worst arm (arm D) |
+
+**PENDING_HUMAN** only for whether to log “universe broaden under current knobs”
+as rejected in the main research index. Strategy knobs unchanged either way.
