Track 3 submission: rework of notch floating bar into a chat-first dynamic island

[katipally]

This is my submission for the Omi Summer challenge (Track 3 — Extra). I already submitted for Track 1 (Agents) #10007 #10088 . While I wait to hear back, I went looking for something in the Omi desktop app I could make meaningfully better, and the macOS notch stood out. The notch already ships; this PR improves its UI/UX so it is clearer to understand and smoother to use. Nothing about what the notch can do was thrown away. I reworked how it looks, animates, and flows.

Where this stands (for maintainers)

This is a first pass I'm putting up so you can actually try the direction. What's here is finished and works; it just isn't a complete, top-to-bottom redesign of the notch. I focused on the core interaction (hover-to-chat, the grow animation, and voice) and kept every existing feature working.

If you like where it's going, I'm happy to double down: finish the full notch design, get every animation buttery smooth and clean, and make sure every feature maps over perfectly. Tell me what you'd change or how far you want me to take it, and I'll finish it out.

The problem I found

The notch is Omi's always-on floating bar, the quickest way to reach Omi without opening the full app. But a couple of things about it get in the way. The animation glitches: three separate drivers run at once and desync, an AppKit window-frame animation (NSAnimationContext + animator().setFrame), a SwiftUI spring on the switcher morph (notchSwitcherProgress), and a scale plus opacity on the reveal (notchRevealProgress), so opening it reads as a fade or a jump instead of an actual grow. The flow is confusing too: the logo (an agent-pills row) opens the agent switcher, and the Ask-Omi button is wired to open the main app window (onAskAI → openMainAppWindow()) rather than letting you chat right in the notch. It never reads as one clean surface.

So I cleaned it up. Same feature set, clearer design: hover the notch and your Omi chat grows straight out of it, with one motion and a flow that does the obvious thing.

What changed, and why it feels right now

• One animation, grown from the notch. The panel is a fixed size per display and never animates its own frame. Only the inner content size and the notch shape's corner radii animate, anchored to the top, so every open literally grows out of the physical notch instead of fading in. The black island is a stable shape layer whose frame always interpolates; content crossfades inside it. I verified the motion by extracting frames from a screen recording and confirming the intermediate sizes are actually there.
• Streaming has its own calm timeline. As a reply streams in, the height rides a separate smooth animation keyed on measured content height. Keeping it isolated from the open/close springs is the whole trick: merge them and the measure loop oscillates. Split, it just breathes.
• Chat-first, no detour. Hovering opens the same shared timeline the main window renders (ChatProvider.mainInstance, not a copy), with a floating glass composer below it (attach, growing field, Return to send, Stop while responding). Ask Omi and the global hotkey now open the notch into chat instead of leaving to the main window. Height fits the conversation, caps at half the screen, and is remembered so the first open doesn't jump.
• Voice you can see. Holding push-to-talk turns the composer into a live waveform, and your words now appear in it as you speak, with a stop button to end the turn. Your question lands in chat the moment speech-to-text settles, and the reply streams under it while Omi speaks. A closed notch auto-opens on the first token. If the free-tier limit blocks PTT, it now shows a visible hint instead of silently doing nothing (that one was a real dead end before).
• A composer that gets out of the way. Sending empties the field instantly (no sent text lingering or reappearing after the reply), and it's put back only if the send never lands. Delegated-agent cards in the timeline are tappable now: tap the card to open the agent, not just a tiny corner icon.
• Omi identity stays put. The omi mark (with the recording dot) and the settings gear are always visible on the closed notch, hugging the camera housing. The gear opens the main window's settings; the mark opens the agents tab.
• Close behavior that respects you. Pointer-based auto-close with menu-aim detection (moving toward the panel never closes it), click-away, Esc, and a short post-open grace. Pointer monitors only exist while a panel is open, so idle CPU stays at zero.

Nothing was dropped

Every floating-bar feature still works after the redesign: PTT voice turns (hub and batch), voice playback settings, proactive notifications (queue, click-through, Execute, dismiss), the Ask-Omi hotkey, agent timeline opens, the recording indicator, show/hide/snooze preferences, the automation bridge (omi-ctl state now tells the truth about the notch), and usage limiting.

Two things I deliberately retired because the new design makes them meaningless: the manual bottom-corner resize (height is fully dynamic now) and the draggable pill preference (every display just gets a notch). The old window and view code stays dormant in-tree so removing it can be its own reviewable follow-up rather than a 7k-line delete buried in this PR.

Product invariants

• INV-CHAT-1: the notch stays an I/O surface over the one kernel transcript. The chat tab renders ChatProvider.mainInstance.messages directly (no copy); the live voice strip is display-only mirror state, cleared once the journaled exchange lands; sends go through sendMainDraft and the kernel-routed query pipeline; snapshot aliases unchanged.
• INV-DATA-1: no routing changes; check-mobile-production-routing.py passes (exit 0) on this branch.
• INV-VOICE-1: PTT lifecycle unchanged. PTTBarPresenter still projects reducer state; the query pipeline keeps owner-bound dispatch, a single terminal outcome, and journal-acceptance semantics. Only the presentation surface moved from the legacy window to the notch state. The live listening pill now mirrors the provider's partial transcript for display only; it never enters the committed turn, which is still governed by the settled final.
• INV-AUTH-1: no session-ownership change. sendMainDraft only clears and restores the local composer draft around the existing send path; it does not touch runtimeOwnerId, session mint, or AuthSessionCoordinator. The send_main_draft bridge action is non-production only and drives the same owner-bound send.

Verification

• xcrun swift build -c debug --package-path Desktop green. ./scripts/agent-logic-harness.sh --swift-only green (INV-6 filter suites included). Full isolated Swift suite run (scripts/swift-test-suites.sh, 351 suites) green.
• Live continuity gauntlet (agent-continuity-gauntlet.sh --suite continuity: typed, PTT, and blind recall against the real backend on a named bundle) passed on this branch's continuity code (passed: true). The chat and PTT files under test are unchanged since that run (verified byte-identical); later rebases only advanced the upstream base over release and changelog commits.
• New hermetic suites: NotchViewModelTests (hover dwell via injected clock, grace, height clamp and persistence, sizing authority), NotchGeometryTests, NotchShapeTests, NotchAutoCloseZoneTests (zone math and menu-aim cone), NotchWindowLevelTests, NotchPresentationLadderTests. No wall-clock sleeps.
• Exercised live on a named bundle (omi-notch-v2): hover-open into chat; typed send streamed back with the same message visible in the main window (one timeline); expansion checked frame by frame; Esc and click-away close; a real hub PTT turn with the listening waveform, a mid-stream capture showing the question above the streaming reply, and the journaled pair landing without duplication; the blocked-PTT hint; open_ask_omi automation opening the notch focused with a truthful omi-ctl state.
• Composer clear verified through the real send path: a send_main_draft bridge action drives sendMainDraft, and after a full turn settles the composer draft reads empty (the sent text neither lingers nor resurfaces).
• make preflight and scripts/pr-preflight pass with this body; changelog fragment, e2e flow covers, and the line-count and test-quality ratchets are all satisfied.

Failure-Class: none

[Git-on-my-level]

Thanks for the thoughtful Track 3 submission — the chat-first notch direction is coherent and the new tests around geometry/presentation are useful. I can't approve or land this as-is yet because I found a couple of blocking integration regressions in the notch rewrite:

1. Disabled/snoozed floating-bar state is bypassed at startup. NotchScreenManager.makePanel calls window.orderFrontRegardless() as soon as each panel is created, and FloatingControlBarManager.setup() starts the manager before checking isEnabled/snooze state. That means the notch panels can appear on launch even when the user had hidden/disabled or deferred the floating bar; the old window path created the window without necessarily ordering it front. Please make initial panel creation respect the persisted enabled/snoozed/deferred state, and only order panels front through the existing show/temporary-notification paths.

2. Some legacy window-based paths are still wired even though the new setup leaves FloatingControlBarManager.window nil. For example closeAskOmiForAutomation now always returns floating_bar_window_unavailable, and deliverAgentArtifactCompletionToFloatingSurface drops completed agent artifacts behind guard let window else { return }. Those are part of the desktop automation/agent-surface contract and need to be ported to notchScreenManager/notchState rather than silently no-oping.

Given the size and UX direction here, this should also get human maintainer/product review after those blockers are fixed. I did not see an attack or supply-chain concern, and I appreciate the regression tests that were added; the remaining ask is to close these integration gaps and include validation evidence for the disabled/snoozed startup path plus the automation/agent-completion paths.

@Git-on-my-level Thanks for the careful review. Both blockers were real and are now fixed, with validation.

1. Disabled/snoozed startup. Root cause: NotchScreenManager.makePanel ordered every panel front the moment it was created, so the launch policy's "hidden" decision was ignored. Panels are now created hidden and visibility runs through a single applyPanelVisibility authority: a panel is on screen when the notch is passively visible OR that panel is explicitly open. That also keeps the old "show temporarily, hide on close" behavior, the Ask Omi hotkey still surfaces the panel while the bar is disabled/snoozed, and it re-hides when the conversation closes.

Evidence (named bundle + Quartz on-screen window list): enabled launch = 2 notch windows, disabled launch = 0, open_ask_omi while disabled surfaces one, close_ask_omi hides it again. Hermetic NotchScreenManagerVisibilityTests assert real NSWindow.isVisible for created-hidden, showAll, hideAll, and summon-while-hidden.

2. Legacy window paths. FloatingControlBarManager.window is never assigned in the notch build, so those paths silently no-oped. closeAskOmiForAutomation now drives notchScreenManager (closeAll + wait) exactly like open_ask_omi, so live close_ask_omi returns a clean result instead of floating_bar_window_unavailable. I removed the dead window field and everything that only reached it (the orphaned notification-reopen helpers, a write-only key, the vestigial PTT resize wrapper). On the agent artifact path: the completion isn't actually dropped, it's already projected into the shared notch timeline via projectJournalTurn (INV-6), so deliverAgentArtifactCompletionToFloatingSurface was dead legacy and I deleted it rather than resurrect the old auto-pop. The ~2000-line legacy FloatingControlBarWindow class is now unreferenced, but I left it for a separate follow-up so this diff stays reviewable.

Green across the board: full desktop Swift suite (352 suites), INV-6 continuity harness, swift-format, SwiftLint, line-count ratchet, e2e coverage. Failure-Class: FC-split-mutation-authority. No merge conflicts with main.

Curious what you both think of this design direction. Worth me doubling down, more features, cleaner UI/UX and animations, pushing it toward a real Apple-native feel? Or keep it minimal for now? Want to build toward whatever fits your vision

i personally love your design but we've been talking internally about removing chat from the notch to take a more verbal first direction when not using the app and keep text inputs within the app.
thanks for the pr though! won't close this yet in case we decide to keep the chat.
