Recorded caveats
- NOT COMPARABLE WITH THE CODING-AGENT COHORTS OR WITH BARE DECISION-LOOP ROWS. This is a jev-astra-hybrid run: GPT-6 Astra and Jev 1.13 were coupled under a protocol that is not the one-shot locked-prompt coding-agent track and not the two-call-per-cycle decision-loop track. cohort_eligible is false. Harry's criterion (same verdict as Astra-alone AND cheaper on API-equivalent) is recorded in the track README; it is not a league-table standing.
- One run per arm. Cannot separate coupling from run-to-run variance.
- Jev cents are negligible; extra spend is Astra tokens.
