Application cleanup

Input: accepted cleanup findings and severities, target, explicit scope, output root, exclusively owned isolated workspace, clean tree, targeted-fix delivery, commit authorization and required build/test commands. Output: phase ledger with pre-phase SHA, candidate snapshot, gate evidence, commit or verified recovery.

Load the project-protocol:project-protocol skill for execution preflight and the canonical gate/recovery procedure. Reuse recorded authorization; ask only for missing choices. Read references/application-cleanup.md inside this skill. Its subtraction method is promoted from Step 7c without adding a new auditor or a semantic refactor engine. Inputs can come from a review or an identified lifecycle plan. When targeted fixes were unnecessary, record 7b as not applicable; otherwise its accepted changes must be delivered and committed before subtraction. Plain --fix leaves this commit-only action open and explains the missing capability before execution.
