AZ Offline — independent research project

This project owns provider integration and persistent playable-media research. It does not require TraraLink for local operation. No provider download/cache implementation or saved playable-audio capability exists in this slice.

Evaluate Apple Music, Spotify and TIDAL independently. For each provider, record the exact client/device version and authorized access mechanism, then distinguish:

Result	Evidence required
Metadata cache	Persistent track/playlist records; no playable-audio claim
Device-bound cache	Actual audio playback after restart/network loss, documented authorization binding and expiry
Portable playable media	Files persist on removable storage and play independently on the declared target, with required authorization and format support established
Recording	Explicitly identified capture; never relabeled as a provider download

Research must cover restart, USB removal/reinsertion, playlist edits, provider changes and interrupted writes. Never advertise metadata-only saving as saved audio. Heavy jobs use the same playback protection and storage ownership rules as other independent AZ tools. Shared music-data helpers remain outside the TraraLink protocol; an eventual optional integration exposes capabilities/jobs.

Provider restrictions, technical feasibility and device resource behavior remain unresolved until primary-source research and authorized practical tests supply evidence. No credentials or provider artifacts belong in public source control.
