 ## Open choices and next discussion
 
+Dictation: plain local transcription is selected; rambling cleanup is deferred.
+The shared Niri module installs Handy and starts it hidden with the desktop.
+Super+D toggles recording; Super+Shift+D cancels. Commands were verified against
+the pinned Handy 0.9.1 source. No microphone recording or model download was run.
+After user activation, launch Handy from Walker, download/select Parakeet V3,
+keep automatic language detection and disable push-to-talk for toggle operation.
+In Advanced, choose paste method None and clipboard handling Copy to Clipboard.
+Keep post-processing disabled. Settings/models remain writable app-owned state.
+Start Handy manually for the current session; desktop autostart applies on login.
+Try an English and a Dutch recording, paste into Codex with Ctrl+Shift+V, then
+submit manually. User feedback needed: recognition accuracy, delay and shortcut
+delivery. Automatic paste can follow if wanted after checking Niri compatibility.
+Verification: formatting, flake evaluation, Zenith and Polaris no-link system
+builds, and whitespace checks passed. No system activation or interactive
+dictation was performed; recognition quality and latency remain unmeasured.

 The focus is the broader environment, not further API/database polish. Candidate
 areas remain places/ownership, navigation/interaction, human/agent collaboration,
 and system operation/maintenance; these are discussion areas, not a work queue.
