What changed

Replaces the dedicated composer effort control's radio list with a horizontal slider: a continuous rail with deterministic quantum specks, discrete tier ticks, and a 27px thumb that tracks the pointer 1:1 and snaps to the nearest tier on release. The composer chip shows a miniature version of the same rail.

Why

Effort is a discrete, model-specific choice (3–7 tiers depending on the harness, e.g. Claude's low → ultrathink), but selecting it through a menu hides its ordered nature. The slider makes the ordinal structure visible — more effort reads as more light — while keeping each option a real tier: drag motion is continuous, commits are always snapped to an actual model option.

Design decisions worth knowing:

  • Grayscale quantum-light language: the fill is a fixed full-width luminance gradient revealed by clip-path, so the leading edge is always the brightest point; 30 deterministic specks inside the fill brighten with effort level and respond locally to the thumb (a velocity-scaled trailing glow while dragging, a faint lift while held).
  • Top tier gets a restrained accent: only the final 28px of the rail takes a 12% accent tint plus a soft thumb aura, honoring --user-accent-color.
  • Drag feel: pointer pick-up preserves the grab offset inside the thumb (no jump when grabbing an edge); release settles over a distance-aware 110–190ms ease with no positional overshoot; thumb deform stays subpixel.
  • Ticks as landmarks: 1×3px marks masked away near the thumb; auto renders as a hollow dot.
  • Fallbacks: prefers-reduced-motion keeps direct tracking but disables twinkle, highlight, and deformation; the effort list inside the model picker's settings menu is unchanged.
  • Accessibility: role="slider" with value text per tier, Arrow/Home/End keys, wheel stepping, Escape/Enter to close, reset-to-default button, and a focus keyline on the thumb (WKWebView's platform focus ring is suppressed deliberately).

UI

Before: menu-style radio list in the popover. After: luminous rail + thumb (dark/light, mid and top tier verified). Happy to attach screenshots or a screen recording — the effect is motion-based and reads much better live.

Effort tiers are discrete and vary per model (3–7 steps, sometimes with
non-ordinal ultracode/ultrathink modes), so a continuous slider would
misrepresent them. The meter lights bars up to the selected tier, echoes
the terminal live-bar and thinking-pulse motifs, and reserves the accent
for the model's top tier. Harness option order differs (Grok lists xhigh
first), so tiers are ranked by name before rendering.

The segmented bars read as a discrete stepper; a smooth track better
matches the mental model of "turn effort up". Tiers remain discrete —
the fill snaps to tick marks and only specks appear inside the filled
portion, brightening toward the right. The model's top tier takes the
accent with a trapped inner glow so the rail reads as luminescent.

Combines two design reviews into a physical model: a recessed track
with inner shadow, a fill that travels to a detached white thumb
center, a fixed speck field revealed through a clip-path so particles
never stretch mid-transition, and an accent confined to a tint overlay
plus an unclipped halo at the final tier only. Dragging tracks the
pointer continuously while the value snaps to the nearest tier on
release; keyboard and wheel steps settle with the shared popover
curve. The chip keeps a static 3-speck mini rail and no longer clips
long tier names.

The carved trough read as a bezel: drop the rail's inner shadows, rim,
and fill sheen for a flat material, and move the focus outline to the
interaction wrapper so it reads as focus, not finish. The thumb is a
flat white disc that dips 4% on press. While pressed or dragging, a
masked copy of the speck field brightens in a 36px band just behind the
thumb, so particles react to the hand instead of only looping on idle.
The external halo is gone; the top tier concentrates accent in the fill
tail and an aura on the thumb. Positional transitions unify at 180ms.

- Drop the custom 14px radius/shadow overrides on the effort popover so
  it shares the standard rounded-xl frame instead of double radii
- Replace the slider's focus outline with a faint keyline on the thumb
- Widen the speck field to 34 sites reaching within ~2% of the rail
  ends, ramp its opacity with effort level, and lift the fill gradient
  toward a brighter leading edge
- Let the fill reach the thumb center exactly

…feel

- Preserve the pointer's grab offset inside the thumb so pickup no longer jumps
- Drive thumb/fill/clip/highlight from one rAF-sampled position and settle
  via a distance-aware 110-190ms ease instead of a fixed CSS transition
- Enlarge the thumb to 27px, fix the gradient full-width and reveal it by
  clip-path so the leading edge stays bright at every tier
- Demote ticks to 1x3px landmarks masked away near the thumb
- Make the speck highlight a velocity-scaled trailing glow, deform the
  thumb subpixel under drag, and rebalance the field to 30 calmer sites
- Confine the top-tier accent to a 28px tail tint and a soft thumb aura
- Suppress WKWebView's platform focus ring; keyboard focus keeps a thumb
  keyline that wins the cascade over the top-tier aura

Publish the wheel callback in a layout effect.

stepRef.current is shared by the native wheel listener, but the render writes it before React commits. If React pauses or abandons that render, a wheel event can read a closure with an uncommitted selectedIndex and commit the wrong adjacent tier. A passive useEffect can also leave the listener using the previous callback until passive effects run. Use the already imported useLayoutEffect.

   const stepRef = useRef((_delta: number) => {});
-  stepRef.current = (delta) => commit(selectedIndex + delta);
+  useLayoutEffect(() => {
+    stepRef.current = (delta) => commit(selectedIndex + delta);
+  });

[error] 420-420: This ref is mutated during render. React can replay or discard render work, so the mutation can leak from UI that never commits.

Move ref writes into an event handler or effect. Render must stay pure because React can replay or discard it. The predictable null-guarded lazy initialization pattern remains supported.

Normalize stale effort values before rendering the meter.

A missing values[setting.id] entry already falls back to setting.value. The issue is a stale override. Restored session records preserve modelSettings, and the initial render can occur before asynchronous reconciliation removes an unsupported value. settingValueLabel then shows the raw value while EffortPicker and EffortMeter select tier 0. Keyboard changes can start from the wrong tier.

-  const value = settingValue(setting, values);
-  const valueLabel = settingValueLabel(setting, values);
+  const configuredValue = settingValue(setting, values);
+  const value =
+    tiers.find((tier) => tier.value === configuredValue)?.value ??
+    tiers.find((tier) => tier.value === setting.value)?.value ??

Add an empty line before opacity.

The configured standard SCSS rules can flag this ordinary declaration because --speck-scale is a custom property and does not satisfy the after-declaration exception. This violates the checked-in style contract.
