Dropped dead job-ID narrative (job 60/64) on rollout_ablate_frac, the
'vanilla step 17' dead-run ref in eval.py, the 'old signed sum' dead-code ref in
proj.py, and the conversational 'current experiment line' lead. Removed the dead
probe-traj justfile recipe. Kept all TODO/FIXME and the 'why' memory-tuning
comments. Smoke green (cout->0).
