The drill was fixed; the reward function is unchanged, so this lineage's learned flight behaviour is kept rather than restarted from Stage 4."
+    "reason": "Discarding 20260821-1516-gen5-s5-intercepts: its own commit+push crashed mid-run (non-fast-forward against a since-merged PR), so it never reached evaluation. Re-resuming from retry2's checkpoint to retry the same post-drill-fix attempt."
