Migrate to Notte

This skill covers one funnel with two entry points:

• Track A — cost comparison only. A read-only, dated, evidence-backed decision brief. It does not modify code, credentials, billing, or provider resources. Run phases 0–3, then jump to §8 (external benchmark context) and §9 (decision brief).
• Track B — full migration. Everything in Track A, then a safe proof, an isolated build, validation, and a reversible handoff. Run phases 0–7, then §9.

Pick the track from the user's request. If they only asked what something would cost, run Track A and stop; offer Track B as the next step. If they asked to migrate, run Track B — a migration without a measured baseline is a rewrite, not a migration.

Use one disciplined process, then load only the reference for the provider discovered in the target. Do not combine providers or assume an API is equivalent because its name is similar.
