Environments (dev / staging / CI)

The start URL origin comes from, in precedence order:

1. --base-url flag
2. WINDUP_BASE_URL env
3. baseUrl in windup.config.ts
4. an absolute start_url in the scenario

An explicit override rebases even absolute scenario URLs (path and query are preserved).

The plan cache is environment-portable: cache identity uses the start URL path, not host/port. A plan generated against localhost:8080 replays on staging or CI with zero LLM calls.

npx windup run checkout --base-url https://staging.example.com
WINDUP_BASE_URL=http://localhost:8080 npx windup run --all
