-#### Θ-W6-T1 — `legibility-and-antialiasing`
+**Θ-W6-T1 has landed** — `legibility-and-antialiasing` — see `docs/COMPLETED.md` for the
+full narrative. It shipped both halves together: knobs grew 28→40 px (inner curve dial
+14→20), the deck cell 48×58→60×74, and the label band 12→16 px, now drawn in
+`Font::Label` rather than `Font::Micro` — group captions and toggle segments deliberately
+stayed `Font::Micro`, since bumping them would outgrow row 1's headroom at the floor
+width. The editor's default/minimum size grew 840×620→980×680 to fit the wider deck at
+floor width; an existing saved instance's window grows on open, and the floor is
+validated by a derived test rather than literals. All fourteen time-constant labels now
+read in ms (display-only; internal representation untouched) — `holdFraction` knobs,
+`Len %`, and the bank panel's duration readout stayed out of scope. Double-click resets
+each ring independently — outer ring resets the value, inner dial resets the exponent to
+1.0 — reaching the chrome's preview-velocity knob too via a shared `inKnobFace` rule.
 
-**Goal.** Make the editor legible — bigger knobs and labels, time constants in ms,
-double-click reset per ring — then audit every drawn surface for high-DPI clean rendering.
+The antialiasing audit fixed knob arcs and needle, the inner dial arc and needle, staged
+and spline envelope slopes, the spline contour, the velocity-popup trace, the waveform
+outline, and the preview triangle; node handles, curve knots, knob discs, buttons, piano
+keys, loop markers, borders, gradients, and text were already clean. The disposition
+table is a standing artifact in `docs/product/visual-design-language.md` §8. The
+piano-key open question is answered: not aliasing — every key is an axis-aligned
+`LICE_FillRect`, so the earlier width defect was integer-division residue in the tiling,
+not a sloped edge. High-DPI host scaling itself is unverified (deferred, see
+`docs/TODO.md`).
 
-**Consolidates items 10, 13.** Sequence internally: sizing first, audit second.

-**Surface boundary — owns:** `core/instrument/ui/knob_deck` (sizing geometry),
-`shell/panel/draw_kit` (the shared LICE draw shell — arcs, lines, slopes), and all three
-Sample-face bands for repaint-level changes. **Note the blast radius:** `draw_kit` is
-shared with the docked bank panel, so an antialiasing change there lands on the extension
-UI too. That is desirable, but it puts the panel in this track's verification scope.
-
-**Behavior — sizing and ergonomics (item 10).**
-- **Radial knobs and their text labels grow** — both are currently too small. No target
-  size was given; this is a visual-judgment change accepted by eye.
-- **Time-constant labels display in ms, not seconds.** A display-unit change; this makes
-  no claim about internal representation.
-- **Double-click on any radial knob resets it to its default value.**
-- **On dual-ring knobs, each ring is its own reset target**: double-click the outer ring
-  resets the time/level value; double-click the inner curve dial resets the exponent to
-  **1.0** (the settled linear neutral) — each independently, without touching the other.
-
-**Behavior — antialiasing audit (item 13).**
-- **A review pass, not a point fix.** Audit each class of drawn surface and confirm it
-  renders with antialiasing (or an equivalent) suitable for high-DPI, high-resolution
-  displays. Where one renders visibly aliased, bring it to the smooth standard.
-- Daniel named the visibly pixely surfaces: **radial arcs, waveform lines, envelope
-  segment slopes.** By the time this runs, those include the inner dials (W3), the stereo
-  lanes (W2-T2), the staged *and* spline segment slopes (W3, W5), the loop markers
-  (W4-T1), and the piano key edges (W2-T3).
-- The outcome is observable, not procedural.
-
-**Acceptance criteria.**
-- Knobs and labels are legibly larger; **Daniel signs off on the result by eye.**
-- **Every** time-constant label reads in ms.
-- Double-click resets any radial knob to its default; on dual-ring knobs, double-clicking
-  the inner dial resets **only** the exponent (to 1.0) and double-clicking the outer ring
-  resets **only** the value.
-- Radial arcs (including the inner dials), waveform lines (including the stereo lanes),
-  and envelope segment slopes (staged **and** spline) render smooth — **no visible jaggies
-  at 100% scale or on a high-DPI display.**
-- **The audit produces a short disposition list**: surfaces checked, which needed work,
-  which were already clean. A required deliverable, not a side effect — it is what makes
-  the audit re-runnable.
-- Daniel signs off by eye on the named surfaces.
-- The docked bank panel is re-verified for regression, since `draw_kit` is shared.
-
-**Open questions.**
-- **Target sizes [verify by eye].** No numeric target was given; item 10's own note is
-  that sizing is judged by eye. Bring a build, not a spec.
-- **Whether the piano-key width defect was aliasing [verify].** W2-T3 fixes uniform width
-  regardless of cause; this audit confirms whether aliasing was the cause and whether the
-  fix survives DPI scaling.
+All visual outcomes remain pending Daniel's by-eye sign-off on `dev`.
