Four gaps found shipping in Opus 4.8 eval samples during human review:
1. low-contrast (extended): the browser adapters parsed text/own-bg
colors with parseRgb only, so Chrome's oklch()-serialized computed
colors silently skipped every contrast check — a flat dark-on-dark
nav CTA (broader nav selector beating the button class) shipped at
1.5:1 undetected. checkElementColorsDOM and readOwnBackgroundColor
now fall back to parseAnyColor. Near-threshold ratios print two
decimals so a 4.497 finding no longer reads "4.5 needs 4.5".
2. NEW numbered-section-labels (slop, advisory): tiny (<=13px) styled
numeric index labels riding beside section headings, repeated across
2+ sections with distinct indices. Sibling of repeated-section-kickers
(which deliberately excludes bare numeric labels); handles both the
direct prev-sibling shape and label-before-heading-wrapper shape.
List/nav/table/card-item numbering is exempt.
3. side-tab (extended): the vertical pseudo-element stripe scan required
the stripe to touch both corners (top/bottom 0 or height 100%), so a
left accent bar inset a few px from each end evaded it; small end
insets (<=20px each) now count. Added a browser-side pseudo-element
check (getComputedStyle(el, '::before'/'::after')) since runtime-
assigned custom-property colors are invisible to the text scanner.
Selection-state exemptions stay as narrowed: only aria-selected=true /
aria-current / active-class markers exempt, plus button/link
affordances on the horizontal variant.
4. NEW repeated-container-text (quality): the same literal string (>=4
chars, contains letters) rendered 3+ times at 3+ structurally distinct
positions inside one bordered/elevated container. Parallel/templated
repetition (table cells, calendar grids, nav lists, identical sibling
rows) never counts — structural signatures, not word lists.
Verified: each rule fires on its repro sample via the file:// browser
scan; clean eval samples add no new findings (the new low-contrast hits
on other samples are genuine sub-AA oklch button pairs). Full test
suite green; browser bundle regenerated; README/homepage rule counts
bumped 49 -> 51 (docs-integrity test enforces them).

Tab-strip MEMBERSHIP no longer exempts chromatic top/bottom stripes —
only a real selection marker does: aria-selected="true", aria-current
(any non-false value), or an active/current/selected class hint. A
stripe repeated on every tab in the group ([role=tab], .tabs items,
aria-selected="false" tabs) is decoration and flags as side-tab; the
selected tab's own underline — including the reserved-space
transparent-border pattern — stays legal. Applied consistently across
the element border path (isTabContextElement), the pseudo-element
stripe scan, and the inset box-shadow stripe scan.
Also replaces a stray NUL byte in the marquee scanner's dedupe key
that made tools treat checks.mjs as binary.

Four gaps from human review of gpt-5.6 eval artifacts:
1. codex-grid-background variants: the block scan now also matches the
inverted end-of-tile hairline form (transparent calc(100% - Npx))
and reads the tile cell from the background shorthand's `/ Npx Npx`
slot, not just background-size declarations. A single hairline layer
qualifies when tiled by a px pair cell (page-scale line field);
percent-tiled single hairlines (background-size: 25% 100% rules on
data-viz tracks/graphs) stay legal.
2. hero-eyebrow-chip branch C (dash-prefix): sentence-case, regular-
weight microlabels above the h1 announced by a short chromatic
::before/::after bar (8-80px x 1-6px, accent fill). Static cascade
marks dash-pseudo targets during rule collection; the browser path
reads getComputedStyle(el, '::before'/'::after').
3. New `marquee` slop rule: <marquee> elements, and infinite animations
bound to keyframes with >= 20 percentage points of X travel. Percent
travel only — px-travel loops are bespoke product animations
(waveform playheads, progress sweeps). Centered elements animating
other properties (constant -50% X), non-infinite slide-ins, rotations,
and pulses never qualify.
4. side-tab inset box-shadow variant: single-edge inset shadows
(3-12px offset on one axis, no blur/spread, chromatic) drawn as
stripes on cards/badges/menu items. Selection-state indicators
([aria-current], [aria-selected], [role=tab], active/current/selected
hints, interaction states) stay exempt; the same stripe repeated
unconditionally on every item flags. Narrow fixed-width glyphs
(logo marks) are exempt. isTabContextElement narrowed to match:
bare nav ancestry no longer blanket-exempts top/bottom border
stripes — only explicit tab semantics or state markers do.
Browser bundle regenerated.

Four changes driven by human design review of eval artifacts:
1. Static engine contrast fidelity (nav-CTA cascade miss):
- parseAnyColor evaluates color-mix() (premultiplied sRGB mix; exact
for the dominant `color-mix(in oklab, C n%, transparent)` chip form)
- extractStaticColor captures color-mix() balanced instead of plucking
"transparent" out of the expression
- resolveBackground composites translucent layers over the opaque base
in both engines instead of skipping (static) or returning them
as-if-opaque (browser)
- NEW hover pass in the static cascade: :hover rules are matched via
state-stripped selectors, merged per-property against the resting
cascade with real specificity, and checked for WCAG contrast on
styled controls (checkHoverContrast). Catches the recurring miss
where a broader selector (.nav-links a:hover) beats the CTA's own
hover color and drops the pair below AA.
2. New `radial-halo` slop rule: chromatic radial-gradient wash (visible
saturated center -> transparent) as a decorative background on a dark
page. Exempts achromatic vignettes, opaque-end sheens, px-stop dot
textures, url() photo layers, and translucent (<0.7 alpha) staged-
light washes. Separate id from dark-glow so dashboards track the
gradient-drawn variant independently.
3. side-tab horizontal variant: 3-12px chromatic border-top/bottom (and
top/bottom-anchored full-width pseudo stripes) on cards/badges flag as
side-tab. Exempt: tablist/nav/aria-selected underlines, link/button
affordances, table cells, hr, state-conditional pseudo stripes, and
>12px bands. Badge-shaped spans (own visible background) participate.
4. CLI: file:// URLs route to the Puppeteer browser engine (~2s on a
50KB page), and detect --json findings now carry the registry
`category` field so downstream QA loops can separate mechanical slop
tells from judgment calls.
Fixture policy update: flat 3px top-accent cards moved from should-pass
to flag columns; tablist-underline and 16px-band pass cases added.
Browser bundle regenerated.

Measure framework and provider latency, enforce fidelity and cleanup gates, and publish reproducible results on the dev-only Live Lab.\n\nAI-assisted: OpenAI Codex.
Two gaps surfaced by human eval review of real artifacts:
1. side-tab missed the pseudo-element variant. The accent stripe drawn as
an absolutely-positioned ::before/::after (left/right: 0, top+bottom: 0
or height: 100%, narrow width, colored background) uses no border
property at all, so neither the element-level border checks (pseudo
elements never enter the static cascade or DOM walk) nor the
border-left/right regexes could see it. New scanCssTextForPseudoStripe
scans stylesheet text for that shape, mirroring the border rule's
gates: >= 3px thick (<= 12px), chromatic fill (var()-resolved, neutral
dividers skipped), full height against a side edge, with the
blockquote/prose exemptions preserved.
2. New pulsing-dot rule (slop): small circular "live" indicator dots
(<= 16px, border-radius >= 40% or pill values) bound to an infinite
animation whose keyframes vary opacity, scale, or box-shadow — or
pulse/blink/ping names when the keyframes aren't in the scanned text —
plus the Tailwind animate-ping/pulse + rounded-full + tiny-size utility
combo. Rotation-only keyframes (spinners) never flag, including when
they hide behind a pulse-like name.
Both scanners live in checkHtmlPatterns, so the static-html engine and
the browser bundle share the same detection path. Browser/extension
bundles regenerated; docs rule count bumped to 47.

Answering the obvious question the family-depth framing dodged: with
modes derived per task, files named for the old two-register taxonomy
had no architectural reason to exist. brand.md's surviving depth (lane
test + inverse test, reflex-reject lanes, color discipline, layout
moves, permissions) folds into new-work.md, where all of it belonged:
it is new-identity Persuade/Experience guidance. product.md's content
moves unchanged to operate.md, its true name. Both old files remain as
one-line redirect stubs because register: brand|product in existing
PRODUCT.md files and older links point there. All cross-references
retargeted (SKILL.md modes intro, context.mjs REGISTER hint, live.md,
typeset.md); 85 tests green.

Architecture per Paul: impeccable is primarily a daily driver on
existing codebases; the always-loaded core should serve that 90% path,
not carry the full generative arsenal on every invocation. SKILL.md now
holds brief-wins, existing-worlds (the headline path), the four visitor
modes, the full craft floor, and a hard gate: new identity work
(greenfield, or a redesign discarding the current look) MUST read
reference/new-work.md before any design decision. That file carries the
generative playbook (seed, subject grounding, plan/self-check/signature,
hero-thesis, everything-bold, prove-don't-claim, color commitment,
calibration, persuade type/imagery). context.mjs enforces the gate
mechanically: NEW_WORK directive when no PRODUCT.md/DESIGN.md exists,
and the old mandatory register-file read is replaced by a REGISTER
family hint. No surfaces: map anywhere; mode is derived per task.
Gate compliance is measurable via skillEvidence.directSkillFileReads.

Eval evidence showed the per-edit PostToolUse stream fires overwhelmingly
on copy-level rules (em-dash-overuse ~97x/session) and measurably makes
models more conservative, while a full-detector pass at completion is what
actually fixes contrast/padding/glow. Split the hook accordingly:
- Per-edit (PostToolUse) now surfaces only IMMEDIATE_TIER_RULES: broken
output (broken-image, text-overflow, clipped-overflow-container,
body-text-viewport-edge), objective contrast/legibility failures
(low-contrast, gray-on-color, tiny-text), single-property mechanical
slop (gradient-text, dark-glow), and design-system drift (the four
design-system-* rules, which compound if left uncorrected). Everything
else defers. Override with hook.perEditRules: "all" in
.impeccable/config.json. Tiering is off for Cursor/Copilot harnesses,
which have no Stop pass wired, so nothing gets silently dropped there.
- Stop deep pass (runStopHook): runs the FULL rule set over every UI file
touched this session (tracked via the existing hook.cache.json session
state; deferred-only edits now mark the file touched), dedupes against
everything already surfaced per-edit, honors ignore-rule/file/value and
inline disables, reuses the [impeccable@1] envelope, and no-ops fast
when no UI files were touched. Emits hookSpecificOutput
{ hookEventName: "Stop", additionalContext } per the Claude Code SDK
Stop contract (conversation continues so the model can act on it).
Second Stop fire is silent - deep-pass findings are remembered.
- Wiring: Stop entries (timeout 30) in plugin/hooks/hooks.json, the
.claude settings + .codex hooks manifests (transformers + hook-admin
repair path). Claude Code and Codex both dispatch a native Stop event;
Cursor's stop hook is inconsistently dispatched (pre-write gate stays)
and Copilot's agentStop/sessionEnd don't inject model context, so
neither gets a Stop entry - documented in reference/hooks.md.
- Tests: tiering split/override/harness gating, Stop dedupe + silent
no-touched-files + ignore machinery + kill switches; existing per-edit
tests moved to immediate-tier rule ids. 181 tests green; smoke-tested
the built dist skill end to end (glow surfaced per-edit, em-dash only
at Stop, second Stop silent).

- parseAnyColor now covers oklab(), hsl()/hsla(), hwb(), and ~35 common
named colors on top of rgb/rgba/hex/oklch, so checkGlow sees the color
regardless of authoring format (Chrome preserves oklch() in computed
styles, which the old rgba-only match silently passed).
- checkGlow gains a second tell: a zero-offset chromatic box/text-shadow
with blur > 4px is flagged on ANY background (the halo pattern);
achromatic zero-offset shadows and focus rings stay legal. The
existing chromatic-blur-on-dark-background rule is unchanged in
semantics but now parses every color format.
- text-shadow is checked wherever box-shadow was (browser DOM path with
inherited-value dedupe, static engine via new textShadow cascade
support, text engines).
- The page-level text scan (regex engine + checkHtmlPatterns) is now a
shared scanCssTextForGlow that resolves single-level var() refs
against custom properties collected from the same text; unresolvable
var() in a shadow color position is skipped, never guessed. Its
dark-page heuristic accepts var()/oklch backgrounds but only when
declared at root scope (body/html/:root or body inline style).
- dark-glow keeps its id; registry name/description updated to cover
both cases.
Validated: three eval repro samples with oklch / var(--x) glows that
previously produced zero findings now flag on the static CLI path; ten
known-good largerun samples stay clean except one with genuine amber
status-dot halos (0 0 12px oklch(.73 .17 65/.4)).
Note: cli/engine/detect-antipatterns-browser.js and the extension
detector are generated and still need 'node scripts/build-browser-detector.js'
+ 'node scripts/build-extension.js' once builds are unblocked.

* Route native projects to native command variants for audit and adapt
Follow-up to #269. The web audit.md and adapt.md carried "translate this
yourself" Platform notes, so a native invocation paid for the full web
file (~1.8k / ~2.6k tokens, mostly inapplicable) and did error-prone
run-time translation. Authored with AI assistance (Claude Code) under
maintainer direction.
- New reference/audit.native.md and reference/adapt.native.md: authored
native content (VoiceOver/TalkBack, platform conformance, adaptivity
dimensions; phone-to-tablet, platform-to-platform, web-to-native
strategies). One variant per command covers ios, android, and
adaptive; per-OS specifics stay in the platform refs Setup loads
regardless.
- SKILL.src.md: Commands table lists the variants; Setup step 2 reads
the variant instead of the web file when the platform is native.
- audit.md / adapt.md: Platform sections replaced with a one-line
web-only guard pointing at the variant.
- animate.md / layout.md: Platform sections deleted; the Motion and
Layout sections of the already-loaded platform refs carry that
content. Web users now pay zero tokens for the platform axis in
these files.
- Skill-behavior scenario 15 pins the route-instead behavior (passes
live on claude-sonnet-4-6); CLAUDE.md documents the variant
convention.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* Phrase command-reference routing as one rule, not rule-plus-exception
Copilot review catch: step 2 said "MUST read reference/<command>.md"
and then carved out the native variant, which invites loading both
files. Now a single rule: read the web reference or the table's native
variant, one file, not both. Scenario 15 re-verified live. Applied with
AI assistance (Claude Code) under maintainer direction.

* Anchor native runs in animate/layout, drop loaded-refs assumption
Review-thread fixes, applied with AI assistance (Claude Code) under
maintainer direction:
- Greptile: deleting the animate/layout Platform sections left native
runs alone with web tooling instructions (CSS keyframes, GSAP, Grid,
clamp()). Restore a one-line anchor in each pointing at the loaded
platform reference's Motion / Layout section (~20 tokens, not the old
restatements).
- Bugbot: audit.native.md and adapt.native.md asserted the platform
refs were "already loaded in Setup", but the command reference loads
at step 2, before step 5. Now they instruct: read the platform
reference first if Setup hasn't already.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* Carry the native-variant rule into routing rules 2 and 3
Bugbot catch: Setup step 2 routed native projects to the variant, but
routing rules 2 and 3 (the operative text at command time) still said
to load the generic reference file. Both now reference the same
one-file variant rule. Applied with AI assistance (Claude Code) under
maintainer direction.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* Point animate/layout native anchors at the files, not "loaded" refs
Bugbot catch, same class as the variant wording fix: the anchor lines
said "the loaded platform reference" but command files load at step 2,
before the platform refs at step 5. Both anchors now name the files and
instruct reading them first if Setup hasn't already. Applied with AI
assistance (Claude Code) under maintainer direction.

* Add a platform axis (web / ios / android / adaptive) to the skill
Orthogonal to register: register decides whether design IS or SERVES the
product; platform decides the delivery target and which native conventions
apply. Set `## Platform` in PRODUCT.md; a missing field defaults to `web`,
so legacy projects are unaffected.
- extractPlatform() in skill/scripts/context.mjs (mirrors extractRegister);
the CLI appends a NEXT STEP directive to read the native reference(s).
`adaptive` (Flutter / RN / KMP shipping both iOS and Android) loads both
ios.md and android.md.
- New reference/ios.md (Apple HIG distilled) and reference/android.md
(Material 3 distilled); reference/web.md is a thin pointer. The native
refs frame register's role as narrow: platform conformance is the bar,
brand lives in the expressive layer the platform gives you, never by
breaking the rails.
- Setup step 5 loads the native reference(s) when platform is native. Live
mode and the detect CLI stay web-only, gated off ios/android/adaptive.
- init asks platform right after register; adapt/audit/animate/layout carry
short platform divergence notes; all secondary spots thread `adaptive`.
- a11y stays in audit.md (loading it at design time makes output timid), so
the native refs carry no Accessibility section; audit.md's Platform
section owns native a11y.
- Tests: extractPlatform unit coverage + skill-behavior scenario 10
(PRODUCT.md platform ios -> agent loads ios.md).
Source-first: only skill/, scripts/, tests/, CLAUDE.md, NOTICE.md, the
changelog and version are committed; the sync workflow regenerates the
provider trees and ./plugin on merge.
ios.md / android.md are distilled from the MIT-licensed
ehmo/platform-design-skills; attribution in NOTICE.md.

* Address review: gate web tools on native platforms, drop version churn
Maintainer-review fixes applied with AI assistance (Claude Code), on top
of the rebased platform-axis commit:
- Design hook (post-edit and Cursor pre-edit) now resolves the project
platform via loadContext + extractPlatform and skips its web rule scan
for ios / android / adaptive projects, so React Native / Flutter code
never draws web-shaped findings (new hook-lib resolveProjectPlatform /
isNativePlatform helpers, covered by unit and subprocess tests).
- context.mjs CLI warns on an unrecognized ## Platform value (e.g. a
toolchain name like `flutter`) instead of silently defaulting to web;
extractRegister / extractPlatform now share extractSectionValue.
- Removed reference/web.md: nothing loaded it; CLAUDE.md carries the
"web has no extra rulebook" explanation.
- init.md: skip live-mode config (Step 6) for native platforms; note the
per-app PRODUCT.md pattern for repos shipping web + native.
- android.md: Material-everywhere apps that also ship on iPhone still
owe iOS OS guarantees (safe areas, Reduce Motion, edge-swipe back).
- ios.md: reworded a design-time line that framed Dynamic Type as an
accessibility check (a11y stays owned by audit.md).
- Renumbered the new skill-behavior scenario to 14 after main's 10-13;
updated CLAUDE.md scenario list; added android + unrecognized-value
CLI test cases.
- No version or changelog changes: versioning happens at release time.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* Tighten platform reference prose
Editorial pass on the platform-axis text, applied with AI assistance
(Claude Code) under maintainer direction:
- ios.md / android.md rewritten to house style: single-line paragraphs
(no hard wraps), one-sentence scope intro, deduplicated intro/slop-test,
register-compression down to two sentences. In-file attribution
paragraphs removed (NOTICE.md owns attribution); "read on top of the
register reference" cruft removed (SKILL step 5 and the context.mjs
directive already say it). Bans sections dropped: they restated the
rules above them; the two additive items (tab-bar overload,
hover-dependent affordances) folded into rules. ~40% smaller each.
- Sub-command Platform sections (adapt, audit, animate, layout), SKILL
step 5, init.md platform prose, and the context.mjs directive trimmed
the same way.
Build (prose validators, counts) and both test runners green.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* Treat an empty PRODUCT.md section as absent, not the next heading
Copilot review catch: extractSectionValue read the next `## ...` heading
as the section value when a field was left empty, which made the CLI
warn "value `## Product Purpose` is not recognized". Stop at the next
heading and return null instead. Regression tests for extractPlatform,
extractRegister, and the CLI warning path. Applied with AI assistance
(Claude Code) under maintainer direction.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* Only read a token list of both native targets as adaptive
Bugbot catch: after the exact platform tokens failed, any Platform line
containing the words ios and android was classified adaptive, so
negated or explanatory prose ("web only, not ios or android") silently
loaded both native refs and skipped the hook, with no warning. The
combo parse now accepts only list separators and the two platform
words; anything else falls through to the CLI's unrecognized-value
WARNING. Regression tests added. Applied with AI assistance (Claude
Code) under maintainer direction.
