This is not just a slower animation. CodexNotch now decides when motion deserves CPU time—and becomes fully static without losing the running or completed signal.

Measured performance

Same Mac, same running-state workload, production builds, 12-second warm-up, and a 60-second process CPU-time sample per build:

Configuration Average CPU Change vs. v0.1.6
v0.1.6 running animation 6.80% baseline
v0.1.7 low-power animation on 4.25% 37.5% lower
v0.1.7 animations off 0.75% 89.0% lower (~90%)
  • Ring frame-request budget: 60 FPS -> 8 FPS (86.7% fewer requests).
  • Wave-ball frame-request budget: 30 FPS -> 8 FPS (73.3% fewer requests).
  • Completion firework timeline: 60 FPS -> removed (100% eliminated).
  • Memory stayed effectively flat at approximately 135-136 MiB; this release targets continuous rendering cost, not resident memory.

These are same-device local measurements rather than universal hardware guarantees, but the benchmark setup and exact numbers are included to make the claim reproducible.

Motion, rebuilt around actual work

  • Motion now runs only while a task is active, app animations are enabled, and macOS Reduce Motion allows it.
  • The ring completes a calmer 3-second cycle within an 8 FPS budget.
  • A new Settings toggle stops continuous motion immediately.
  • Disabling motion keeps a full-brightness solid quota ring instead of a dim frozen gradient.
  • Static running and completed cues remain clear: quota percentage, green ChatGPT mark, and completion checkmark are preserved.
  • Hover expansion and collapse now switch immediately inside the proven fixed-canvas architecture.
  • The transparent canvas is reclaimed immediately after collapse, so unused space cannot keep intercepting the pointer.

Less animation, not less information

  • Removed the card expand/collapse transition.
  • Removed the completion firework and its 60 FPS particle work.
  • Preserved top-anchored notch geometry, quota warning colors, Reduce Motion behavior, and task-state priority.

Privacy improvement

  • The notch mark is now embedded directly in CodexNotch.
  • CodexNotch no longer opens or reads another application's bundle just to render the mark.
  • This removes the decorative icon's dependency on macOS App Management permission.

Verification

  • 43 behavior contracts validated.
  • 98 tests passed with zero failures.
  • Production build, app bundle, Info.plist, and ad-hoc signature verified.
  • ZIP checksum verified.
  • DMG checksum, read-only mount, Applications shortcut, and mounted app bundle verified.

Requirements

  • Apple silicon (arm64)
  • macOS 14 or later
