## Investigation Brief

Rendering candidates are only actionable when the dynamic behavior is accidental. First prove that the route can be static, ISR, or partially static.

## Evidence To Check

Inspect `dynamic`, `revalidate`, `generateStaticParams`, route params, and dynamic APIs such as request headers or cookies. Check whether the dynamic call is in a layout, because that can affect a larger route tree.

## Do Not Recommend When

Do not remove dynamic rendering for auth, personalization, draft mode, per-request redirects, or request-specific data.

## Verification

The recommendation must cite the dynamic trigger and explain why the target route can tolerate static or ISR behavior.
