+Generate SFT warmup traces for PERMANENCE's training pipeline.
+
+Critical correctness property (learned the hard way in Run 5 attempt 1):
+
+    The prompt a warmup trace uses MUST be produced by the live environment,
+    not by a hand-written summary. Run 5 attempt 1 used short hand-written
+    summaries like ``=== OPS - Step 1 | Task: Integrated Deploy === ...`` but
+    the actual env emits the long structured prompt ``=== SCENARIO — Step
+    1/20 | Task: Integrated Deploy === ... TEAM: ... PROJECTS: ...``. The
+    model SFT'd cleanly on the short format (loss 0.43) and then produced
+    complete garbage on the long format because it had never seen it.
+
+    Gate coverage went 100% → 50% solely because 2 of 4 tasks happened to
+    have train/eval prompt structures that didn't overlap enough.
+
+    This file now generates every warmup prompt by calling
+    ``PermanenceEnv.reset(seed=...)`` so the training distribution exactly
+    matches the GRPO/eval distribution.
