WaveController 0.0.2.4 prealpha

1. System Default Output & Input Management:
   • Interactive Default Toggle: Added "Make OS System Default Output / Input" switch in the Mix Edit popover with active
   green badge indicators.
   • Mutual Exclusivity: Enforced single-default constraints across mixes of the same type (toggling a new default
   automatically demotes the previous default).
   • WirePlumber Compatibility: Upgraded virtual input mix node class to Audio/Source to support OS-level default input
   designation via wpctl set-default.
   • Clean Teardown Fallback: When an active default mix is deleted, WaveController automatically falls back and designates
   Personal Mix (or Chat Mix) as the active OS system default.
2. Device Settings & Dynamic UI Anchoring:
   • Permanent Top Anchor: Pinned the Primary Default Device / Set as Default Device card at Position 1 on the Device Settings
   page.
   • In-Place UI Updates: Replaced destructive DOM re-attachment with non-destructive visibility toggling and inner row
   updating to prevent the section from dropping to the bottom on runtime refreshes.
3. Port Sanitization & Group Channel Presentation:
   • Numbered Port ID Filtering: Stripped raw PipeWire port numbers (121, 90) and numbered prefixes (121 Shortwave:output_FL →
   Shortwave:output_FL) from Grouped Application lists.
   • Deduplication & App Mapping: Unified multi-channel Left/Right stream links into single, clean application cards.
4. VU Metering Isolation & Zero-Bleed Invariants:
   • Zero-Fallback Autoconnect Gating: Added -P node.autoconnect=false and -P stream.dont-remix=true to all pw-record meter
   processes, preventing WirePlumber from re-linking orphaned meter taps to Discord when YouTube/Chrome stops playing.
   • Strict Canonical Token Matching: Filtered container wrappers (chromium, webrtc voiceengine) and replaced fuzzy substring
   matching with strict exact-token lookups so quiet channels strictly report 0.0.
5. Performance & DOM Caching:
   • Matrix Cell State Caching: Prevented unnecessary GTK widget and slider recreation during matrix redraws and channel
   reordering.
   • Group Drawer Sub-Strip Caching: Cached member application lists to eliminate UI churn when expanding or collapsing group
   drawers.
