Use when verification is looping, would re-run untouched code, or duplicates an established proof. Not for tasks that require source or remote-system changes.

# Lighter checks

## Contract

| Field | Bound contract |
|---|---|
| Trigger | Checking has started to loop, a check would re-run against untouched code, a second tool would prove what the first proved, or the user asks to stop over-checking and ship. |
| Authority | Read-only. No file, VCS, credential, paid, published, deployed, or remote mutation. Emits a delivery decision only. |
| Side effect | Run scoped typecheck, lint, and test verification once per touched language, trim redundant verification, and report whether delivery may proceed. |
| Done | One proving action has run per claim, no action was repeated for reassurance, each touched language's complete project gate ran once, and the result is delivered on the first green gate. |

## Inputs

Required inputs are the claims to prove, the changed files or explicitly bounded changed surface, the languages touched, and the project's typecheck, lint, and test commands for those languages. Supplied results must include their command, scope, and outcome. Never assume an optional input establishes evidence.
