#21659 cmux-next: a static status look, on under Reduce Motion (cx-sya4n)

Under macOS Reduce Motion, cmux NEXT's status indicators now stand still on the Static set's glyphs, whatever Debug icon set is picked (sidebar rows and every other StatusIndicatorView). Those are #20410's StaticStatusGlyph shapes: a half-filled ring for work, an empty bubble for waiting, a shield for permission or sign-in, a check disc and a ! diamond. Before, Reduce Motion only stopped the icon set's animation, so the Codex-like set fell back to a still ring and the other sets to whichever mark they stopped on (cx-sya4n: blinking lights give a teammate headaches).

• StatusIndicatorSettings.animation (animated by default, or static) and Reduce Motion together make StatusIndicatorConfig.isStatic. A later slice adds the setting's row to the Settings page.
• StatusIndicatorPlan.make(isStatic:) draws the static look: StatusIconSet.still's plan with no animation. Loading keeps its style's still glyph, and known progress keeps its ring.
• Leo's call on #20511: the Static set's glyphs are the default. #20511's StatusMark shapes stay available behind a new Debug toggle, status.static.shapes (Debug Settings > Status Indicators). The shapes are a dot, hand, ? bubble, key, !, x in a ring, check and empty ring.
• plans/cmux-next/status-indicators.md describes the look.

Tabs, tooltips and VoiceOver labels, the attention ring and the agent pane pick up the look in a later slice of #20511. No user-facing strings: the toggle is Debug-only, and its label is plain text like the other status tunables.

Testing

• StaticStatusLookTests (CmuxNextDesignTests) checks:

  • Every icon set draws the Static set's plan with no animation in the static look.
  • The shapes toggle gives all nine states distinct still shapes.
  • isStatic follows the setting and Reduce Motion, including the pinned override through StatusIndicatorAppearance.
  • A StatusIndicatorView under Reduce Motion shows the still working and permission glyphs with no running animation.

  The test is committed first (47a80171505), where it's red as a compile failure. The fix is ecb86951cf7. Neither has run yet: this host is Linux, so this PR's macOS CI lane is the first run.

• Locally on Linux:

  • check-motion.sh passes and lint-swift-post-edit.sh is clean.
  • In verify-local.py --affected origin/feat-cmux-next, localization-defaults, project-tests, test-wiring, feature-flags and backend-migrations passed.
  • xcstrings, localization, project, package-groups and launch-policy failed on files this diff doesn't touch: catalogs missing from the sparse checkout, existing needs_review entries, and the Xcode project.

Changelog

Changed: in cmux NEXT, Reduce Motion shows still status glyphs (one shape per state) instead of stopped animations.

Summary by cubic

Under macOS Reduce Motion, cmux NEXT's status indicators now stand still with a distinct glyph per state instead of a frozen animation frame, whatever icon set is selected.

Details

• StatusIndicatorSettings.animation (animated or static) and Reduce Motion both drive the new static look; Reduce Motion always forces it.
• The static look draws the Static set's glyphs by default; a Debug-only toggle status.static.shapes switches to distinct StatusMark shapes.
• Loading and known progress keep their arc/ring glyphs, just still.
• Tests cover glyph selection, the shapes toggle, and isStatic following the setting and Reduce Motion.
