The -worst of those three is shown: - -| Role | Light | Dark | Worst light | Worst dark | -| --- | --- | --- | --- | --- | -| `StatusInfo` / `AccentColor` | `#0000FF` | `#4DA3FF` | 6.76 | 6.47 | -| `StatusPositive` | `#008035` | `#30D158` | 4.54 | 7.62 | -| `StatusWarning` | `#AD5100` | `#FF9F0A` | 4.59 | 7.76 | -| `StatusCritical` | `#CC0700` | `#FF6961` | 4.68 | 6.12 | -| `StatusNeutral` | `#5A5A5F` | `#A1A1A6` | 5.84 | 6.76 | - -Each status foreground has a matching `…Surface` colour for the fill behind it, -paired through `AppStatusTone`. - -### Contrast alone is not a palette - -The first version of this palette maximised contrast and produced mud. Requiring -every foreground to clear 4.5:1 against *its own 16% tint* — the harshest -surface it ever sits on — pushed each colour ~20% darker than the common case -needed. `#7A5600` is not amber, it is olive; `#146C2E` is not green so much as -bottle-dark. Contrast passed and the UI was still hard to read, because hue -identity is what tells "warning" from "critical" at a glance. - -Two fixes: - -1. **Decouple the fill from the foreground.** `AppStatusTone` carries a - `foreground` and a `surface` that are authored independently, so the - foreground no longer has to survive a wash of itself. Every status foreground - is now fully saturated (`S = 1.0`). -2. **Warning is orange, not yellow.** Yellow cannot stay yellow at a lightness - low enough to clear 4.5:1 on white — it *becomes* olive. That is - colorimetric, not a tuning problem. Orange holds its identity when darkened, - so warning is `#AD5100` in light and `#FF9F0A` in dark. - -When adding a colour, search for the most saturated value that passes, not the -darkest. The darkest is always easy and always wrong. -| `AppTextSecondary` | `#5A5A5F` | `#A1A1A6` | 6.15 | 7.50 | - -`AppTextSecondary` replaces `.secondary` for body text. iOS's own `secondaryLabel` -is only **3.29:1** on a light card — below AA — which never showed while the app -was locked to dark, where the same colour reads 6.32:1. Unlocking light mode -exposed it across 191 sites. - -High Contrast variants push further in the same direction. Surfaces -(`AppBackground`, `AppSurface`, `AppSurfaceElevated`, `AppSeparator`) carry no -meaning, so they get Any/Dark and, where useful, High Contrast — but no status -semantics. - -Why custom values instead of the system palette: **every** system colour fails -in light mode. Measured on white — systemYellow 1.51:1, systemOrange 2.20:1, -systemGreen 2.22:1, systemCyan 2.54:1, systemRed 3.55:1. All of them pass in -dark mode, which is why the dark-locked app looked fine and why unlocking light -mode is impossible without this work. - -### The accent has two roles, and they conflict - -An accent used as **text on a dark background** must be light. The same accent -used as a **fill behind a white label** must be dark. One value cannot do both: -`#4DA3FF` reads at 8.00:1 as text on black, but only 2.63:1 behind white text. - -So there are two colours: - -- `StatusInfo` / `AccentColor` — the accent as *foreground*: text, icons, - bordered-button labels, tab bar. -- `AccentFill` — the accent as a *filled background* behind a label, used by - `.borderedProminent`. Stays dark in both schemes so a white label clears AA - (8.59:1 light, 7.56:1 dark). - -`AppOnAccent` is the label colour for a solid accent fill and flips by scheme — -white on the light accent, black on the dark one. - -## Appearance - -`AppAppearance` (System / Light / Dark) is stored in `@AppStorage` and applied in -**exactly one place** — the `WindowGroup` in `DomainDigApp`. Keep it that way. The -app previously carried 16 separate `.preferredColorScheme(.dark)` calls scattered -through view bodies, which is how light mode became unreachable without anyone -noticing; re-applying per view is what let the lock spread. - -Users override it under Settings → Display. - -### Known light-mode findings - -| Finding | Cause | Action | -| --- | --- | --- | -| 2× `contrast failed` on Settings | The last rows of a section sit under the translucent tab bar, so the audit measures text against a blended background. Present in dark mode too, since phase 0. | None — standard iOS scroll-under behaviour | -| 3× `contrast nearly passed` on Settings | iOS-rendered `Section` headers (`TIER`, `PREFERENCES`, `SERVICES`) use the system's grey. | Not fixed. Overriding system header styling across every section to gain ~0.3:1 on decorative labels trades platform convention for very little | - -Dark mode reports 18 findings and light mode 21; the three extra are the section -headers above. Everything the app actually controls passes in both schemes. - -## Enforcement — the ratchet is engaged - -With phases 1–5 landed, `AccessibilityAuditHarness.enforcedAuditTypes` enforces -**`.textClipped`, `.dynamicType`, `.hitRegion`, `.elementDetection`, -`.sufficientElementDescription`, `.trait`** on the empty-state test suite. A -named finding in any of these fails CI — regressions in five phases of work are -now gated, not merely reported. - -Three deliberate carve-outs, each with its evidence: - -1. **`.contrast` stays report-only.** The two long-standing Settings findings - are rows scrolled under the translucent tab bar; their attribution flips - between a row name and nil run-to-run, so no suppression is narrow enough to - keep CI stable. The centralised palette in `Shared/Colors.xcassets` is the - actual guard against contrast regressions. -2. **The seeded tests run `reportOnly`.** Bisecting the row/badge accessibility - modifiers showed the audit degrades on `children: .ignore` content — the - *correct* VoiceOver treatment for dense rows — emitting unattributed - contrast/dynamicType failures on rows that measure 6–7:1 and render - correctly. Their burndown still prints; it just doesn't gate. -3. **Characterised noise is suppressed narrowly and always logged** with a - `[noise: reason]` marker — disabled controls (WCAG 1.4.3 exempt), "nearly - passed" near-misses, system field placeholders (clipped at any length — - proven by shortening them to no effect), and unattributed - clipped/dynamic-type artifacts. Nothing disappears silently; see - `noiseReason(for:)` for each rule's provenance. - -Enforcement is a committed constant rather than a CI setting, for two reasons. -Environment variables do not work: neither a plain `xcodebuild` env var nor a -`TEST_RUNNER_`-prefixed build setting reaches the UI test process, so the toggle -silently did nothing. And a committed value makes "when did clipping become -enforced?" answerable with `git blame` instead of CI tribal knowledge. - -## Why coverage is split between local and CI - -**Audit coverage is not nested across OS versions.** Each runtime reports -findings the others miss, in *both* directions. Measured on this project: - -| Screen | iOS 18.6 | iOS 27.0 | -| --- | --- | --- | -| Tracked Domains | 2 (text clipped) | **6** (+ contrast ×3, element detection) | -| Settings | 2 contrast | **`dynamicType`** finding 18.6 missed | -| Dashboard @ `AccessibilityXXXL` | **hit region** + 2 clipped | 1 clipped only | - -Neither runtime is a superset, so the oldest supported OS needs its own run. -This also rules out committing per-screen baseline counts as a regression guard: -no single number is correct on both. - -The catch is that **GitHub's `macos-26` image ships only iOS 26.x simulator -runtimes.** It cannot test the 17.6 floor at all. A two-job CI matrix was tried -and produced two near-identical 26.x runs at double the macOS minutes. - -So the work is split by what each side can uniquely do: - -| | Runtime | Uniquely provides | -| --- | --- | --- | -| **CI** (`.github/workflows/build.yml`) | newest available | A clean checkout of the merge result — catches a file that was never committed, which a local run cannot. Matters here because `DomainDig.xcodeproj` is hand-edited and uses file-system-synchronized groups, where a whole missing folder still builds locally. | -| **Local** (`Scripts/audit-a11y.sh`) | oldest supported + newest | Real floor coverage, on a machine that actually has an 18.x runtime installed. | - -Together they cover both ends; neither duplicates the other. - -## Running it - -```sh -./Scripts/audit-a11y.sh # floor + current -./Scripts/audit-a11y.sh floor # oldest supported only (~85s) -./Scripts/audit-a11y.sh current # newest installed only -``` - -The script reads the deployment target from the project rather than hard-coding -it, and selects the oldest installed runtime **at or above** it — a runtime -below the deployment target is useless, because the app cannot install there. -If the nearest installed runtime is a major version above the target, it says -so rather than implying floor coverage it does not have. - -### Pre-push hook - -```sh -git config core.hooksPath .githooks -``` - -Runs the floor audit before a push, and only when Swift, asset, or project files -changed. Bypass with `git push --no-verify`. - -Pre-push rather than pre-commit deliberately: the suite takes ~85s, and at -pre-commit that blocks every commit. A hook routinely bypassed with -`--no-verify` is worse than no hook, because it trains you to ignore it. - -## Layout gotchas found the hard way - -- **`Label` clips its own title.** Every empty-state heading reported as clipped - text. `.fixedSize` applied to the `Label` does not reach the `Text` inside it, - so the fix is to split it into an `HStack { Image; Text }` and put the modifier - on the `Text`. Changing the font design did **not** help — that hypothesis was - tested and discarded. -- **Splitting a `Label` exposes its icon to VoiceOver.** `Label` folds the image - into the title's accessibility element; an `HStack` does not, so the icon - starts announcing its raw SF Symbol name ("checklist.unchecked"). Decorative - icons split out of a `Label` need `.accessibilityHidden(true)`. -- **Placeholder text is always reported as clipped.** Search prompts and - `TextField` placeholders are flagged regardless of length — shortening - "Search portfolio" to "Search" changed nothing. Treat `textClipped` findings on - a `searchField` or `textField` element as noise rather than shortening useful - prompts to chase them. -- **`AppLayout.minimumTapTarget` is the floor for every control.** `@ScaledMetric` - scales *down* below the default text size as well as up, so a scaled dimension - needs `max(scaled, AppLayout.minimumTapTarget)` or it drops under 44pt for - users who prefer smaller text. - -## VoiceOver conventions - -- **Dense rows use combine-for-summary, custom-content-for-detail.** - `BatchResultRowView` and `WatchlistRowView` each hold 8–9 text elements. - Reading them inline makes a long sweep unnavigable, so each row is one element: - `.accessibilityElement(children: .ignore)` + domain label + status value, with - the rest on `.accessibilityCustomContent(...)`. `.high` importance is spoken - inline; everything else reaches the More Content rotor on a vertical swipe. - Rows with only 3–4 elements (the portfolio activity/attention/expiry rows) are - left to `NavigationLink`'s automatic combine — custom content is for the dense - case, per WWDC21-10121. -- **The custom-content chain must live in a `ViewModifier`.** Inlined onto a row - body, six `.accessibilityCustomContent` calls plus the visual layout blow the - Swift type-checker's budget ("unable to type-check in reasonable time"). - `BatchRowAccessibility` / `WatchlistRowAccessibility` exist for that reason. -- **Splitting a `Label` exposes its icon; combining a header swallows its - trailing controls.** Two opposite traps. A decorative icon pulled out of a - `Label` needs `.accessibilityHidden(true)`. A header built as a `Button` must - *not* get `.accessibilityElement(children: .combine)` if its label contains - other controls (`CollapsibleSectionView`'s `trailing()` holds Track/Pin) — - combine would merge them into the header and make them unreachable. -- **Label-in-name (WCAG 2.5.3).** Every `accessibilityLabel` added to a control - with visible text keeps that text, so Voice Control still works. Free-form - labels are used only where the control is genuinely icon-only. -- **Technical strings** get `speechStyle: .technical` on `InfoRowViewData`, which - applies `.speechAlwaysIncludesPunctuation()` and - `.accessibilityTextContentType(.sourceCode)`. Set today on DNS record values - and cipher suites; extend it wherever the view model emits a fingerprint, - serial, or record string. - -## Color independence, motion, transparency - -- **Status is never colour-only.** In-app badges already pair a symbol with the - colour. The widget status dot is now an SF Symbol - (`checkmark.circle.fill` / `exclamationmark.triangle.fill` / - `exclamationmark.octagon.fill`) — the same vocabulary as the badges, so a - status reads consistently across surfaces and survives greyscale. -- **`accessibilityDifferentiateWithoutColor`** adds redundant shape only when the - user asks for it, avoiding clutter otherwise: the Dashboard summary-card dot - becomes a per-filter symbol, the selected quick-filter chip gains a checkmark - and border (selection was fill-colour only), and `LabeledValueRow` prefixes a - warning/failure symbol. -- **`accessibilityReduceMotion`** guards all five animation sites via - `withAnimation(reduceMotion ? nil : …)` / `.animation(reduceMotion ? nil : …)`: - `AppCopyButton`'s check cross-fade, `CollapsibleSectionView`'s expand/collapse, - `TimelineDiffView`'s scroll, and `WatchlistView`'s list reorder. -- **`accessibilityReduceTransparency`** swaps the single `.thinMaterial` for an - opaque `AppSurfaceElevated` capsule. - -These cannot be verified by `simctl`, which toggles only Increase Contrast — the -other three settings live in the simulator's Settings app. They are correct by -construction and build-clean; their runtime behaviour is part of the Phase 6 -manual pass. `SweepActivityController` was dropped from the motion list: it is -pure ActivityKit lifecycle with no animation to guard. - -### What the automated audit cannot check - -`performAccessibilityAudit()` validates descriptions, traits, contrast, hit -regions, and clipping. It does **not** exercise VoiceOver speech, the More -Content rotor, custom-content ordering, or announcements. Those are verified by -construction and a manual VoiceOver pass (Phase 6), not by the suite. A green -audit is necessary, not sufficient, for the row and speech work. - -Additionally, the dense rows (`BatchResultRowView`, `WatchlistRowView`) and the -widget never render in the audit — the test simulator has no tracked domains or -batch results. Their treatment is unverified by the suite for the same reason the -Phase 3 `ViewThatFits` work was deferred: absence of findings is absence of data. - -## Notes - -- **Disabled controls are a false positive, and are suppressed.** WCAG 1.4.3 - exempts inactive components from contrast requirements, but the audit flags - them anyway — Inspect's Run button is disabled until a domain is typed, and - auditing the empty state reported a contrast failure that was never a real - defect. The harness now drops contrast findings whose element reports - `isEnabled == false`. Suppressing on the rule beats driving the UI to enable - the control: typing raises the keyboard, which then follows the audit onto - later screens and flags the system emoji picker's category buttons. -- **A dirty simulator inflates the burndown.** Keyboard state persists across - runs, so a simulator left with the emoji picker open reports ~9 phantom - hit-region findings per screen. If findings appear that name system UI - ("Flags category", "Frequently Used category"), erase the simulator - (`xcrun simctl erase `) and re-run before believing them. -- Audits retry up to three times. Slower machines can miss the audit's internal - deadline (`Audit failed to complete in time`, code `-56`), which is a tooling - timeout, not an app defect. A screen that still cannot be audited is reported - as an `XCTSkip`, never a pass — skips are visually distinct in CI, so an - unaudited screen stays visible instead of being silently counted as clean. -- The suite launches with `DOMAIN_DIG_FORCE_PRO_PLUS` so Pro-gated screens are - reachable. `PurchaseService` honours that argument in `DEBUG` builds only. -- Everything used is available at the iOS 17.6 deployment floor; - `performAccessibilityAudit` is `ios(17.0)`. -- cgit v1.2.3
