## What it does [#what-it-does]

Deep-dive follow-ups once a file, symbol, or route is ALREADY in view: test/breaking-change/refactor impact, React/route context, canonical-symbol search, proof certificates.

## When to use it [#when-to-use-it]

**Use when:** "what tests cover this" · "which tests would catch a regression here" · "prove this route is actually guarded"

**Also use when:** a prior result already named the target

## When not to use it [#when-not-to-use-it]

no file, symbol, or route named yet — get one first via strata19.compute\_change\_impact (basic blast radius) or list\_files/a finding
