Migration guide from Jupiter Metis (v1) or Ultra to Swap API v2.

Tokens, turns and time describe resource use, not a dollar price.
One of 20 test cases the skill fixed. Same model, same prompt, with and without the skill.
We are refactoring our API query parameters for Jupiter's unified build endpoint. In v1 we passed `userPublicKey` to specify the wallet initiating the swap. What parameter name must we send in v2?
| Checked | Without skill | With skill |
|---|---|---|
| Specifies replacing userPublicKey with taker. | Missed | Passed |

| Source | Target | Effort | When to choose |
|---|---|---|---|
Ultra → /order | GET /swap/v2/order + POST /swap/v2/execute | Minimal (URL change only) | Default for Ultra users |
Metis → /build | GET /swap/v2/build | Moderate (parameter + response mapping) | Need transaction composability |
Metis → /order | GET /swap/v2/order + POST /swap/v2/execute | Moderate (flow change) | Don't need tx modification, want managed execution |
Each path has a dedicated example with before/after code, parameter mappings, and response changes:
/order — Minimal migration, base URL change only/build — Consolidates 2 calls into 1, parameter and response mapping/order — Flow change to managed execution with multi-router competitiontest cases passed, vs 4 / 25 without
