 ## 8. Antialiasing disposition — the drawn-surface audit
 A standing inventory of every class of drawn surface and how it answers antialiasing, so the
 audit is re-runnable rather than a one-off sweep. **The rule the table applies:** an
 axis-aligned fill or hairline has no aliasing to remove — LICE's `aa` flag is inert on a pure
 horizontal or vertical run — so "already clean" there is a statement about geometry, not a
 concession. Everything with a slope or a curve must draw through a primitive that antialiases.
 **Primitive gotchas this audit established (verified in `vendor/WDL/WDL/lice/`):**
 - `LICE_Line` takes INTEGER endpoints. `aa=true` antialiases the span, but the endpoints are
  still quantized; `LICE_FLine` keeps float endpoints and `LICE_ThickFLine` is *always*
  antialiased and adds width.
 - `LICE_FillTriangle` takes **no** `aa` parameter at all — its sloped edges alias, and the
  only fix inside the kit is to re-stroke those edges with an AA line in the same ink.
 - LICE has no thick-arc primitive. A wider ring is drawn as adjacent 1 px `LICE_Arc` calls at
  stepped radii, which keeps every ring antialiased.
 - A min/max waveform column plot cannot be antialiased by the column fill itself (the columns
  are vertical). The outline is what reads as jagged, so it is stroked separately.
 | Surface | Where | Disposition |
 |---|---|---|
 | Radial knob track + value arc | `editor_internal.h` `drawKnobFace` | Was AA (`LICE_Arc`, 1 px). **Widened** to a 3 px stacked-radius ring; the bigger knob is what made 1 px read thin. |
 | Knob needle | `drawKnobFace` | **Fixed** — was integer-endpoint `LICE_Line`; now `LICE_ThickFLine` (always AA, float endpoints, 2 px). |
 | Inner curve dial arc + needle | `drawInnerDial` | **Fixed** — 2 px stacked-radius arc; needle moved to `LICE_FLine` with float endpoints. |
 | Staged envelope segment slopes | `editor_paint_waveform.cpp` | **Fixed** — `LICE_ThickFLine` at 2 px, replacing integer-endpoint `LICE_Line`. |
 | Spline (drawn EG) contour | `editor_paint_waveform.cpp` `paintSplineOverlay` | **Fixed** — same treatment, one trace grammar. |
 | Velocity-curve popup trace | `editor_paint_curve.cpp` | **Fixed** — same treatment. |
 | Velocity-curve mini thumbnail | `editor_paint_curve.cpp` | Left at 1 px AA `LICE_Line` — a 2 px trace blots at thumbnail scale. |
 | Waveform min/max columns | `draw_kit.cpp` `drawWaveform` | **Fixed** — column fill unchanged (it cannot alias), plus an AA `LICE_FLine` stroke joining each column's extremes to its neighbour's, in the same ink. Shared with the docked bank panel and the browser cards. |
 | Preview play triangle | `editor_paint_chrome.cpp` | **Fixed** — `LICE_FillTriangle` has no `aa`; its two sloped edges are re-stroked with AA `LICE_FLine`. |
 | Envelope/spline node handles (squares) | `editor_paint_waveform.cpp` | Already clean — axis-aligned `LICE_FillRect`. |
 | Envelope curve knots (circles) | `editor_paint_waveform.cpp` | Already clean — `LICE_FillCircle` with `aa=true`. |
 | Knob body disc | `drawKnobFace` / `drawInnerDial` | Already clean — `LICE_FillCircle` with `aa=true`. |
 | Buttons | `draw_kit.cpp` `drawButton` | Already clean — `LICE_RoundRect` with `aa=true`. |
 | Piano key faces + edges | `editor_paint_chrome.cpp` `drawKeyboard` | Already clean — axis-aligned fills and a vertical hairline. **See §8.1.** |
 | Loop span, crossfade region, marker bars, grab tab | `editor_paint_waveform.cpp` | Already clean — axis-aligned fills. |
 | Group fences, card/tab/tooltip borders, focus rings | deck, browse, panel painters | Already clean — `LICE_DrawRect`, axis-aligned. |
 | Surface fills + inner edge highlights | `draw_kit.cpp` `fillSurface` | Already clean — `LICE_GradRect` + axis-aligned hairlines. |
 | Embed strip (TCP/MCP) | `reasampler_embed.cpp` | Already clean — axis-aligned fills only. |
 | Docked bank panel chrome | `panel_render.cpp` | Already clean — axis-aligned fills, rects and hairlines. Its only exposure to this pass is the shared `drawWaveform`. |
 | Text | `draw_kit.cpp` `text` | Already clean — `LICE_CachedFont` AA glyph cache (§1.1). |
 ### 8.1 Was the piano-key width defect an aliasing artifact?
 **No.** Every piano key is an axis-aligned `LICE_FillRect` with an integer width, so there is
 no sloped or curved edge for aliasing to act on — the defect could not have had that cause.
 It was integer-division residue: `keyboard_strip` tiles same-class keys at one integer width
 and the indivisible remainder of the band width has to go *somewhere*. The fix put it in
 symmetric end margins instead of in a key, which is arithmetic, not rasterization.
 **Does the fix survive DPI scaling?** At the client-pixel level, yes — key widths are uniform
 by construction at every client width the strip's test sweep covers. Above that level it is
 **unverified**, and for a structural reason worth keeping visible: nothing in the instrument
 implements `IPlugViewContentScaleSupport`, so a host that scales the plugin window resamples
 the already-rasterized uniform widths at the physical-pixel level, where the guarantee no
 longer applies. That is a host-scaling question, not an antialiasing one, and it is recorded
 as a gotcha in `src/core/instrument/CLAUDE.md`.

 - `browser_scroll` — scroll + type-to-filter layered over `capture_browser`: vertical scroll offset, scrollbar thumb, thumb-drag mapping, and name-substring search.

 - `embed_strip` — compact single-row control layout for embed mode in the track FX chain.
- `knob_deck` — pure knob-deck layout + hit-test (FB1): group-box / caption-row / compact-toggle / knob-cell geometry, deterministic whole-group wrap, `DeckLayout` / `DeckHit`.

That is what lets a mode flip drop controls from a face — Trigger's AMP and FILTER ENV lose their Sustain/Release stages — without either reflowing the deck or leaving dead slots in the box; a face with fewer controls simply gets roomier cells.

+- `knob_deck` — pure knob-deck layout + hit-test (FB1): group-box / caption-row / compact-toggle / knob-cell geometry, deterministic whole-group wrap, `DeckLayout` / `DeckHit`. Mirror of `action_bar`/`param_slider`; no LICE or REAPER types. Carries a SECOND hit-test, `hitTestKnobFace`, resolved against the drawn CIRCLES rather than the cell: a double-click reset is aimed at a dial, so the label band and the cell margins must miss where a drag grab deliberately does not, and only a radial resolve can tell the inner curve dial from the outer ring it sits inside. **The cell/knob/label sizes and `sample_bands`' editor floor move as a pair** — wider cells need a wider floor width or the deck wraps to a fourth row. A group carries TWO caption-toggle slots, laid right-to-left: the second exists because a group whose knob row is wider than its caption row has caption slack a toggle can occupy for free, and the deck has six pixels of headroom on its first row at the editor's floor width — a `rowToggle` would widen the GROUP and wrap the deck to a fourth row, past what the minimum window holds. **A group's cell run is a RESERVED WIDTH, not a fixed cell size**: a `-1` id reserves one cell's width without a cell, and the cells present divide the whole run between them at one uniform integer width (residue in symmetric end margins).

 - `deck_values` — the deck's control-id ↔ parameter-set BINDING and its display units, split
  from the editor shell on the same axis `deck_groups` was split from `knob_deck`: `deck_groups`
  says which controls exist, this says what each one's value MEANS. Holds `deckParamNorm` /
  `setDeckParam` (the normalized ↔ stored-seconds/fraction/position maps and their clamps),
  `resetDeckParam` (the double-click reset — the defaults are READ off a default-constructed
  `PlaySeconds`, so there is no second table of defaults to drift), and `formatEnvTimeMs`, the
  ONE time-constant formatter: every displayed time constant reads in **ms**, never seconds, so
  two stage times are comparable at a glance. A display-unit decision only — nothing about the
  stored representation changes. Links the map layer because `PlaySeconds` is what a deck edits.
  The shell keeps only the controls the parameter set does not carry (key-track, voice count,
  master gain, preview velocity) and the labels for them.
 - `deck_groups` — also home to `isLiveDeckParam` and `liveCommitFor`, the editor's whole commit-tier routing decision (see "Live parameter delivery" above), and to `OverlayEnv` + `nextOverlaySelection`/`overlayEnvEnabled`/`overlayEnvInert`, the whole overlay-selection state machine (exclusivity, the none resting state, and which selections a disabled or DRAWN group makes inert); WHICH groups the Sample face's deck carries, split from `knob_deck`'s HOW they lay out: the `DeckParam` control-id space (the editor's `ParamControl` is an alias of it), the `DeckGroupId` list, `sampleDeckGroups` in signal-flow order (**pitch → filter → amp**, then velocity/voice/master), and the deck's bipolar-knob law. Reads `PlayMode` for the AMP group's Gate/Trigger face, which is why this and not `knob_deck` is the module that touches the engine's value layer. Also home to `CurveTarget` + `curveTargetFor` — the VELOCITY group's three cells are popup openers, not dials, and that predicate is the ONE place they are named, so paint, hit-test routing and the popup's title all agree. MASTER is reserved for post-voice-mixer concerns, which is why the curves sit in their own group immediately left of VOICE rather than there.
 - `spline_edit` — THE point-editing grammar, and the one place it is written down: left-click grabs a node and adds one in empty space, right-click deletes, control-click toggles hard/smooth. Both spline consumers — the velocity-curve popup and the spline EG overlay — route their mouse-down through `resolveSplineEdit`, so the two cannot drift into two grammars. The endpoint and point-count rules are NOT restated here: `deletePoint` and `addPoint` own them, and the caller applies the resolved action to the curve. Also home to `splineOverlayBox`, the contour's mapping box inside the waveform overlay — the FULL area, no inset, so the drawn contour stays 1:1 with the sample's time axis.
 - `curve_popup` — pure curve-popup geometry + dismissal test (FB1): centered sheet over the Sample face — width/height clamps, title row, Close button rect, curve-box rect, outside-sheet dismissal test. Mirror of `overflow_menu`; no LICE or REAPER types.
