App Functions — Save, Test & Publish

Save only after a clean validate pass (salla-app-functions-validate).

Save (create or update)

An app has one function, keyed by its trigger, so get / save / delete take app_id and trigger. save is an upsert for that trigger's function.

• Save: salla_functions action=save, app_id, trigger, content (the whole function as a string), name. Keep the template's first line exactly. Returns a deploy job and triggers an async deploy to the app's demo stores — poll salla_functions action=deploy_status, job (returned by action=save) until COMPLETED, then test it (salla-app-functions-test). One save covers deploy; there is no separate deploy action or versioning.
• Read: salla_functions action=get, app_id, trigger → template + types (.d.ts URLs) + the app's saved content (or null).
• Remove: salla_functions action=delete, app_id, trigger.
