description	Structural-only cleanup pass — dead code, simplification, AI-slop rejection — with zero behavior change, always its own S-commit.
stage	meta
source	base
mode	advisory

Purpose

Remove dead code, simplify, and reject AI-slop (fake certainty, generic checklists, dead abstractions, warning suppression) without changing any observable behavior. Tidy First's structural half — the counterpart to hima-forge's behavioral changes.

When to use

• On request ("clean this up", "remove dead code", "simplify") at any stage.
• As a scheduled sweep after a feature ships, before hima-stewardship's health scan.
• Never as a per-commit gate — this is invoked, not forced.

Steps

• Identify the target: a file, module, or diff range — never the whole repo blindly.
• Find dead code, duplicate logic, and slop patterns (fake certainty, unverified claims, generic checklists that don't trace to a requirement).
• Simplify without changing inputs/outputs — verify with existing tests, not new behavior.
• Split any accidental behavioral change into its own commit; never mix S and B.
• Commit as S (structural) per Tidy First — one intent per commit.

Done when

• Tests pass unchanged (same green/red status as before the pass).
• Commit is tagged S, contains no behavioral diff, and is atomic.
• No new dead code or slop was introduced by the cleanup itself.
