# Sentence Modification
Section 3582, First Step Act § 404, Rules 35 and 36, and vehicle-specific appeal classification.
This page is a verified navigation layer. The linked canonical modules, atomic claims, authority cards, and structured controls remain the legal source; this index does not create a rule from omission or shorthand.

## Stage use controls
- Start with the actual docket posture and controlling court, not the desired remedy.
- Calculate every deadline from its stated triggering event and current computation rule.
- Separate jurisdiction, venue, prerequisites, merits, burden, proof, remedy, review, and appealability.
- Use the circuit overlay for any circuit-sensitive proposition and stop at records marked `not_verified`.
- Preserve the operative filings, orders, transcripts, exhibits, agency record, and proof of filing or service.
