- [x] Tests to add (non-happy path/edge cases): instructions: link to non-existent port; link output-to-output or input-to-input; remove node while link is initializing; create two links to same port and validate policy behavior.
- [x] Performance tests: instructions: create 200 links between existing ports; measure create+destroy time and verify subsecond target where possible.
- [ ] Milestone 4 - Persistence and "ephemeral source" policy
- [ ] Implement persistence (JSON or TOML) for: virtual nodes, links, and per-app routing rules. Persist on change; load on startup.
- [ ] Implement policy engine:
- [ ] Watch for node/port appearance; apply stored rules to auto-link ephemeral sources to preferred sinks.
- [ ] Store mapping by rule (app identity -> target sink/source). Avoid serial IDs; use stable metadata (app/process/role).
- [ ] Allow user override to update rule and persist.
- [ ] Integrate metadata store for defaults and routing hints using libpipewire-module-metadata (see src/modules/module-metadata.c). Track default.audio.sink/source and default.configured.audio.sink/source for stable defaults; use a dedicated warppipe.* metadata namespace to avoid conflicts.
- [ ] Tests to add (non-happy path/edge cases): instructions: rule for app that disappears and reappears under a different PID; verify re-routing; conflicting rules (two matches) resolved deterministically; persistence file corrupted; metadata module not available.
- [ ] Performance tests: instructions: simulate 200 ephemeral sources (connect/disconnect) and measure time to apply routing rules and create links; ensure rule lookup is O(1) or O(log n).

- [ ] Milestone 5 - Stability, compatibility, and tooling
- [ ] Provide a simple CLI (optional) to inspect nodes, create virtual nodes, link/unlink, and export/import config (useful for manual testing).
