Carmine Paolino 3a4db99577 Write the project's boundaries down
CONTRIBUTING.md says what fits and what does not: no other audio
sources, no DRM circumvention, no browser engine, no telemetry, no
hosted service. AGENTS.md and the Copilot instructions hold coding
agents to the same lines, the issue forms and a pull request template
ask for the reading up front, and CI now runs the full battery by
default: clippy and tests with and without features, doc lints, and
the docs site build. The guide's "does not do" list catches up with
lyrics having shipped and says why lossless is out for now.

Fastpotify agent guide

Follow CONTRIBUTING.md; it is the canonical product and contribution policy. These instructions add implementation constraints for coding agents.

Product boundaries

  • Keep Fastpotify a small native Spotify client. Do not add a browser engine, telemetry, a hosted backend, or alternate sources for Spotify audio.
  • Playback capabilities come from librespot. Do not advertise or implement a capability merely because its name appears in a protobuf or enum. In particular, do not pursue Spotify Lossless or DRM circumvention unless lawful support first lands upstream.
  • Do not broaden a task into adjacent features or a general refactor. Preserve existing user behaviour unless the task explicitly changes it.

Architecture

  • src/ui/ draws views and emits Actions. Apply actions after drawing in src/app.rs; do not mutate application state from inside a borrowed view.
  • Network and playback work belongs on the runtime in src/backend.rs or in the player engine in src/player.rs, never as blocking work on the UI thread.
  • Keep platform integrations behind target-specific modules or cfg blocks. A fix for one platform must keep the other two targets compiling.
  • Settings and state files must remain readable, backward compatible, and atomically written. Never log credentials or authorization responses.
  • Prefer existing dependencies. Explain any new crate in Cargo.toml next to the dependency when the reason is not obvious.

Read docs/_reference/how-it-connects.md before changing authentication, Spotify requests, Connect, credential storage, or network behaviour. Read the nearby module tests before changing a state machine or API fallback.

Definition of done

  • Add focused regression tests for changed behaviour. Use the demo feature for deterministic UI coverage and screenshots.
  • Update the README and docs when user-visible behaviour, settings, files, or network access changes.
  • Run the full checks from CONTRIBUTING.md. Do not weaken a lint, delete a test, or add an allow merely to make CI green without explaining why the underlying rule does not apply.
  • Report platform coverage honestly. Do not claim a platform was tested when it was only compiled or reasoned about.
