Repo Working Notes

Test And Debugging Baseline

Use Docker/Linux for installs, builds, and tests by default.
Treat the CI environment as the source of truth:
- Ubuntu/Linux
- Node 24
- npm ci
- npm test
Do not spend time fixing Windows-only runtime or dependency issues unless explicitly requested.
Do not commit repo changes whose only purpose is to make local Windows execution work.
If a failure appears only in the local Windows shell, do not treat it as a code regression until it reproduces in Docker/Linux.

For this fork, validate payment-related changes through the Docker-based workflow before judging safety to commit.
When Docker is unavailable, fix Docker availability first rather than switching to Windows-specific debugging.
