Site-specific content model
The field-manual layout uses a technical vocabulary for Android requirements, contextual permissions and parsing or storage errors. Each observation is tied to a device response rather than a promotional claim about the package.
Capture labels: SDK requirement, architecture hint, parser message, permission category, install-source setting, storage class and package replacement warning.

Editorial boundary
This independent guide does not claim an official relationship, a guaranteed outcome, a verified package version or a universal fix. It organizes observable checks so the user can describe a problem accurately.
Any current version, payment, eligibility or account rule must be confirmed on the destination visible to the user. The guide never asks for credentials, OTPs or payment details.
