Defaults are the storage defaults AND the semantic defaults — this table is the one default authority, and the defaults are CSS's: a bare node is a block, content-box, flex-direction row, flex-shrink 1 (rules/RULES.md: the web is the standard).

The path is stroked; a filled state is its own role, `<role>-fill` for Apple's `<name>.fill`, whose path is a filled silhouette (even-odd, so a cutout is a subpath). Two roles may share an Apple glyph when Material draws their meanings apart (`reorder`, `menu`); the Apple name then answers to the earlier row.

Each is a length at every `textStyleBodies` body size, read at the root font size as a text style's size is (UIKit's Dynamic Type): `accessory-checkmark-width` and `-height` are the checkmark accessory of UIKit's list cell, measured on the iOS 27 simulator at each content size category (`~/audits/exact2-no-tells-2026-10-11/grouped-symbol-probe/ramp.txt`; the 13 body, which iOS has no category for, is the 14's scaled), which grows with the text to AX2, steps back at AX3 and grows again. The `list-symbol-` ramps are a list cell's leading symbol, measured the same way on iOS 27.0 under the system's text size (`UIListContentView`'s layout guides and the drawn symbol, a `star` and a `gear`; a window's trait override lays the cell out otherwise): through the standard sizes `-width` and `-height` scale the sheet's 24 by 20 slot as UIKit's drawn symbol grows and `-inset` is where the text starts (UIKit's `textLayoutGuide`); at the accessibility sizes they are UIKit's image box (`imageLayoutGuide`, which steps back at AX3 as the checkmark does) and the text's first line, 16 past it. `-pull` and `-gap` keep the symbol at the cell's 16-point margin and the text at that inset. UIKit wraps the text's later lines back under the symbol to the margin, which a slot beside the text does not. `accessibility-stack-gap` is 8 through the largest standard size and wider than any line at the accessibility sizes (from the 28 body, AX1): as the gap between items of a wrapping row, it stacks them there, as UIKit's value cell and a hand-built cell's stack of labels turn vertical (`prefersSideBySideTextAndSecondaryText` off).",

  "_metrics": "@ref LLP 1115.002 D6, D8.4; LLP 1115.000 D17: the looks Exact draws itself, as data. Each row: a name, its kind, then its value in each column: iOS, the Mac, the web's first look (LLP 1116 D1) and the neutral look (LLP 1115.000 D4 part B). A row of three cells (a name, a kind, a value) is the neutral look's own and has no value in the other columns. A seventh cell is Android's Material look's (LLP 1115.001.001 D2.4): Compose Material 3's value at the pinned version, which `host/android/reference/rows.json` traces to its symbol and `tokens.mjs` checks against the pinned source; a row without one reads the web's first look's there. The `field-` and `state-` rows at the end are the Material look's own. A process reads one column (`style::metrics::column`): its platform's where an Apple host said it (`set_column`); the neutral look's where the process shows that look's colours (`style::roles::set_column`, the one switch for the look's colours and its metrics), which the web does and a host that paints its own controls with no platform toolkit under it, the Linux desktop and Windows (D17); Android's Material look's where Android's reader says it; else the web's first look. The kinds say what reads a row. `style`: the CSS value of the style row it is written on: a number of px (or a row's bare number: a weight, a flex factor), a keyword (`auto`, `right`, `mini`, `flex-start`), a percentage, a text style or a colour role by its own name, a `light-dark()` pair, or `unset` for no row at all in that column. `style length` (LLP 1121 stage 11 B, theme2's unit flag): a `style` row written on a length property (a gap, an inset, a corner, a width or height, a padding, a margin, an offset), whose number is px; the build holds the marker to the row's name both ways, and a base scale cell may name only such a row or a `length` one. A sheet the compiler writes names it as `-exact-<name>` and holds no number of its own; an author never writes one (lowering refuses the name, and the runner refuses it on a row its author wrote). The kernel reads the name as its value in the process's column when the row is set, so every reader and the wire see the value; the web's JS target, which keeps no kernel, reads a bound name in its build's column when it compiles (`host/web-js/src/style.rs`, `metric_map`). `length`: px as a number, or text in `em` (of the control's font size) or `rem` (of the root's). `number`: a ratio, a weight or an opacity. Code reads these two (`style::metrics::length`, `number`, by the row's place in `generated::metric`): the kernel's size for a control no host measured (`ControlKind::default_size`), and the Linux painter's shapes (`host/linux/src/paint/look.rs`). `unset` in any kind is no value in that column. A state is a row of its own, named for it: `-coarse` on a touch device (the web's `any-pointer: coarse`: any coarse input, normally a touch screen), `-hover`, `-pressed`. The `grouped-` rows are the grouped list's (`list appearance=\"auto\"`, `contract/lower/src/grouped.rs`): iOS's and the web's first look's are the sheet's values as they were (UIKit's measured list, LLP 1084 §2; the three surfaces still its literal pairs), the Mac's are SwiftUI's grouped `Form` measured on macOS 27.0.1 (LLP 1115.002 §1 and stage 4's as-built; `~/audits/exact2-no-tells-2026-10-11/mac-structure/` and `mac-grouped/`; a section is at most 744 wide there: the form's 704 and the card's 20 either side; a row is `border-box` with its insets as padding, LLP 1084 D7, so its minimum heights count its padding: the Mac's 36-point row is 36 here, and `grouped-button-` rows keep a destructive row the Mac's content-box push button), and the neutral look's are the first look's on the neutral grounds with a surface's corners. `popover-radius` is the corner of the default surface a host that paints a popover draws under one whose author wrote none (the `defaultSurface` prop): iOS's is UIKit's popover, Liquid Glass (`backgroundMaterial`'s `glass`) with 30-point continuous corners, measured against a presented `UIPopoverPresentationController` on the iOS 27 simulator (the edge profile of a `UIGlassEffect` view matched it best at 30 of 16 to 40); `popover-shadow-y`, `-blur` (CSS's blur radius) and `-alpha` (black's) are the faint shadow UIKit's popover casts beyond its glass's own, fitted the same way below and above it on a white page, in the light appearance only (over a red page UIKit's dark popover casts none); the web's first look holds iOS's values as every row does, and the web, the Mac and the neutral look draw their own (the UA's style, the system popover). The rows after them are the neutral look's metrics, which the web's sheet (`host/web/neutral.css`, and the shell's where the look keeps it) writes as CSS and `host/web/tests/neutral-look.test.mjs` holds to this table: a control is `control-height` tall with `control-radius` corners and a `control-line` edge; a surface that floats or groups has `surface-radius` corners; a mark (a checkbox, a radio, a switch's and a range's height) is `mark-size`; elevation is flat, `raised-` or `modal-`. Four of them have a value in every column, because the kernel sizes a control by them in every look: `mark-size`, `switch-width`, `switch-height` and `range-height` are Chrome's bare controls outside the neutral look (the switch WebKit's box), what an Apple host shows before it reports its own and Android's reader paints.",

  "_scale": "@ref LLP 1121 stage 11 B (ruling 3, theme2's approvals 09:56 and 10:57). The base scale: nine names an app's views read with no design defining them (`space.xs` to `space.xl`, `radius.sm` to `radius.full`), each a length in each column the metrics table has, and the terminal's. Each row: the name, then its cell for iOS, the Mac, the neutral look, Android's Material look and the terminal. There is no web column: every web build draws the neutral look, so `Column::Web` (a process that says no column, and Material's fallback) reads the neutral cell (theme2, 2026-10-19). A cell is never a bare number: it says where its value comes from, and the build refuses any other form (no arithmetic, no literal without a source). `=<metric>`: that metrics row's value in the same column (a `length`, or a `style` row's px), read when the kernel builds, so the cell cannot drift from it; only where the metric names the same role (a row's inset is space.md, a row gap space.sm, a control's corner radius.md, a card's or surface's corner radius.lg, a mark's corner radius.sm). `{\"stretch\": \"=<metric>\", \"why\": \"…\"}` (LLP 1121 stage 13 D5): that metrics row's value as `=<metric>` reads it, for a role it doesn't name, where theme2 ruled the stretch; `why` says why in a line, and docs/scale-measured.md's `=<metric>` entry under Role stretches gives the measurement and the ruling (the Mac's space.xl). `{\"px\": n, \"measured\": id}`: a value measured on the platform, `id` an entry of docs/scale-measured.md saying what was drawn or read, where, how and the number (scripts/measure-scale.mjs). `{\"px\": n, \"guideline\": id}`: a value a published guideline states (Material 3's spacing and shape scales), or the neutral look's own steps (LLP 1115.000 D17), `id` an entry of the same page with its citation. `full` (radius.full only): one oversized length, `style::scale::RADIUS_FULL`, which every host clamps into a pill by CSS's corner-overlap rule. The terminal's cells: `{\"cells\": n}`, a spacing of n cells (`n ch`), and `0` for a radius, which a terminal never draws. Units are px (points) with no Dynamic Type scaling (ruling 6; QUEUE has the opt-in). A kernel test holds every cell to its source and each look's steps in order (xs \u2264 sm \u2264 md \u2264 lg \u2264 xl, radius sm \u2264 md \u2264 lg; radius.full left out); `style::scale` is the one table any reader of the base takes (the design server's describe, resolve and explain read it in stage 10's D).",

Each row: the name, WebKit's `-apple-system-*` alias or empty, UIFont's and NSFont's TextStyle, its weight in each column of the metric table (web, iOS, the Mac, neutral: the Mac's `headline` is bold, its `caption2` medium), the size at each body size in `textStyleBodies` (the root font size the host sets), and its leading in each column, a line height over the size, or null for `normal`, the face's own (LLP 1115.000 D12.2, measured with NSFont.preferredFont on macOS and UIFont.preferredFont on an iOS 27 simulator, where every style's line height is the face's natural one). The ramp is Apple's: 13 is the Mac's (NSFont.preferredFont, macOS 11), 14 to 53 iOS Dynamic Type's categories xSmall to AX5 (17 is Large, the default; the web's 16 reads Small's row).
