rc-desloplisted

# Remove AI code slop Check the diff against main and remove AI-generated slop introduced in the branch. This edits; it is the cheap sweep that runs before every commit. `rc-simplify-review` is the expensive read-only counterpart that reports on over-engineering — reach for that one when the question is "did this need to exist?", not "is this written like a human wrote it?". Keep behavior unchanged unless fixing a clear bug, and prefer minimal, focused edits over broad rewrites. ## Focus Areas - Extra comments that are unnecessary or inconsistent with local style — this repo's convention is **no comments in code**; keep only pre-existing ones that already match the surrounding file. Never strip a comment that states a constraint the code cannot show (a safety invariant, a workaround with its reason, a `ponytail:` marker naming a deliberate ceiling). - Defensive checks or try/catch blocks that are abnormal for trusted code paths. Never remove input validation at a trust boundary, error handling that prevents data loss, or a security control — those are not slop, however defensive they read. - Casts to `any` used only to bypass type issues - Deeply nested code that should be simplified with early returns - Other patterns inconsistent with the file and surrounding codebase ## Guardrails - Keep the final summary concise (1-3 sentences).
