+## 2026-07-08 — Microphone noise cancellation (iteration #81)
+- **Task:** PROPOSED item — system-wide background noise filtering for voice calls.
+- **Did:** Enabled `services.easyeffects.enable = true` in `modules/home/default.nix`.
+- **Verified:** V1 (flake check).
+- **Pending:** nothing.
+- **Next suggestion:** continue tackling the PROPOSED backlog queue (e.g. `smartd`).

+- **Task:** PROPOSED item — fix black screens when sharing Wayland desktop in X11 apps via `xwaylandvideobridge`.
+- **Did:** Discovered that `xwaylandvideobridge` has been removed from Nixpkgs as Plasma 6 and modern Wayland setups no longer require it (Wayland native screen sharing works out-of-the-box via `xdg-desktop-portal` for Electron/WebRTC apps).
+- **Verified:** N/A (skipped).
