Debug — iOS App Debugging Loop

Authorisation rule

Edit code only when an instruction asks for a fix. An explicit fix request, or a standing instruction that the fix serves (for example "get the app building"), authorises ordinary code and test edits; do not ask for that approval again. A symptom report, or a failure you observed yourself with no such instruction, authorises diagnosis only: report the cause, state the exact change you would make, and ask before you edit (principle-investigate-read-only). When a fix is authorised, stop and ask again only when the proved fix needs a materially different, destructive, or externally visible action, such as deleting stored data or resetting a shared store (principle-stay-in-scope).
