Megatron Migration Generator

Generate implementation-oriented migration artifacts for MindSpeed only after upstream change analysis and impact mapping have narrowed the work to a high-confidence set of items. The goal is to port the upstream feature into MindSpeed with the upstream commit as the primary reference, not to emit a tiny patch hint.

Default Output Mode

Default to report + patch, and generate the final markdown deliverable in Chinese unless the user explicitly requests another locale.

Do not default to direct code edits or automatic commits. Default to an implementation-first package, not a minimal patch sketch.

Supported Modes

1. report Produce a migration report only.
2. patch Produce a migration report plus a full implementation reference package. Default to per-feature folders containing full.patch, split patches/, upstream reference metadata, implementation checklists, and explicit uncovered scope.
3. apply Edit the local workspace without creating a commit. Use only when alignment and impact confidence are high.
