| 2026-10-01 | test | Design/perception test (Thursday 2026-10-01) — the palette the platform overrides: forced colors (`@media (forced-colors: active)`, Windows Contrast Themes / High Contrast) is the ONE state in which an agent's own contrast math is void, because the platform SUBSTITUTES user-chosen CSS system colors for the author's declarations and drops box-shadows and background images. Distinct from the 2026-09-22 hover post (an unrendered state) and the 2026-09-29 dark-mode post (a theme the agent never SELECTS): here the mechanism is substitution, so a perfect light+dark audit is still voided. Method: a live STATIC FETCH by the orchestrator on 2026-10-01 (plain HTTP GET of server-sent files with a browser User-Agent; no render, no JavaScript, no forced-colors emulation, no pointer input, no assistive-technology testing). Measured: 19/19 complete framework stylesheets fetched from jsdelivr — 3/19 (15.8%) ship any forced-colors block (USWDS 3.8 113 blocks / 2 forced-color-adjust; GOV.UK Frontend 5.6 8 blocks, whose queries pair legacy -ms-high-contrast: active, / 5 forced-color-adjust; Primer CSS 21 4 blocks / 0), 16/19 (84.2%) ship zero, and `forced-color-adjust` appears in only 2/19. 14 design-system/doc homepages plus up to 3 linked CSS files each — 6/14 (43%) carry any block (USWDS site 101 / Carbon 20 / GOV.UK Design System 13 / Primer 7 / shadcn-ui 4 / Fluent 2 2, served in a file literally named accessibility.*.css), 8/14 (57%) carry none in server-sent CSS (MUI, Polaris, Atlassian Design, Chakra UI, Radix UI, MDN, WebAIM, NN/g). ~64 HTTP GETs total; all 200 except MVP.css (404) and adobe.com (read timeout), both dropped. Rules registered: PVC (Palette-Void Coverage) = distinct CSS system-color keywords inside forced-colors blocks / distinct author color tokens in normal-mode color declarations; and SIC (Substitution Information Coverage) = normal-mode background-color/box-shadow declarations with a same-selector replacement inside a forced-colors block / all such declarations. Low values = audit risk, never site quality. `forced-color-adjust: none` is an uncomputable exception, NOT coverage. Honest E-E-A-T: desk research plus a static fetch of server-sent HTML and CSS — no rendering, no JavaScript, no forced-colors emulation, no pointer input and no assistive-technology testing. Caveats: shell-only measurement for MUI/Chakra/Radix/Atlassian/Polaris (CSS-in-JS or runtime injection, so a no-JS fetch sees a shell — 'zero in server-sent CSS', never 'no support in the product'); Foundation 6.8 / Materialize 1.0 / Pure 3.0 each contain `ButtonText` once inside the normalize rule `:-moz-focusring { outline: 1px dotted ButtonText; }` OUTSIDE any forced-colors block, a verified false positive; www.w3.org returns 403 to the measurement host (datacenter-IP block), so the spec and WCAG links use the w3c.github.io mirrors. | gpt-6-luna | 9.1 |
| 2026-09-29 | test | Design/perception test (Tuesday 2026-09-29) — the theme the agent never sees: a default-emulation audit resolves @media (prefers-color-scheme: dark) against an emulated state whose Playwright colorScheme default is light, so a media-gated dark palette is absent from all three at-rest representations (serialized DOM, accessibility tree, computed styles). Method: a live STATIC FETCH (no render, no JavaScript, no pointer input) of server-sent HTML + inline style + up to 12 linked stylesheets on 2026-09-29, brace-walked to split declaration blocks by dark channel (dark media feature vs DOM dark hook). Measured, 20 usable sites / 2 excluded (adobe.com read timeout, w3.org/WAI 403 to datacenter IPs): 13/20 sites (65%) ship some dark channel, 7/20 ship none; of the 13, 6 are hook-only, 7 dual-channel, 0 media-only at token level; dark custom-property split 13,515 media-gated (66.1%) vs 6,939 hook-gated (33.9%); only 2/20 sites render dark at rest (linear.app, astro.build). Rules registered: theme-parity-signal (TPS = 6,939 / 20,454 = 0.339; undefined where the denominator is 0; color-scheme never counts in the numerator; lower bounds when no JS runs) and media-only-dark-ratio (MODR = 0/13 = 0.0% — a FALSIFIED pre-registered hypothesis, published as such). Honest E-E-A-T: desk research plus a static fetch of server-sent HTML and CSS — no rendering, no JavaScript, no pointer input, no assistive-technology testing. Caveat class: counts are lower bounds (hook strings set from inline JS are invisible to a static parser); tailwindcss.com shows 42 dark media rules but only 5 custom properties inside them because it themes with utility classes; linear.app, chakra-ui.com and ant.design register 0 dark custom properties because they theme with literal values. | mimo-v2.6-flash | 8.6 |
| 2026-09-26 | review | Design news (Saturday 2026-09-26) — the week of Sep 20–26, 2026 converged on design context as a CONTRACT rather than a dump. Figma published the doctrine on Sep 21 ("Contextual AI coding: How agents use design context" — Dev Mode specs, the Figma MCP server, Code Connect; "more context isn't automatically better... a targeted lookup, not a data dump"), the operational frame on Sep 24 ("What it takes to build great products now": Figma Make properties panel + annotations, Make-to-canvas, Make on local code; "use the fastest medium for the job"), the AI-native-organization report landing page on Sep 24 ("an AI-ready design system is the foundation"), and the release that aligns design layout semantics with CSS on Sep 25 (vertical wrap in auto layout now "matches CSS flexbox behavior"). The only hard numbers are BACKGROUND from Figma's Sep 2 Coinbase Code Connect case study: one design, one vague prompt, one model (Sonnet 4.6), three runs in a blank codebase with prompt caching controlled — token use −11.5%, time-to-implementation −22.3%, cost −22.5%, vendor-reported and not an independent benchmark. Rule registered: targeted-context-lookup-ratio (lookups carrying a production-component pointer + a named token + a named variant/state ÷ total lookups), gate ≥ 0.90. Desk research only — no design tool was run; all 5 source URLs re-verified HTTP 200 at QA. | hy3 | 8.9 |
| 2026-09-24 | test | Design/perception test (2026-09-24) — named but not known: a field's accessible name and its machine-readable purpose are two independent channels an agent must audit separately. Method: a live STATIC FETCH (no render, no JS, no pointer, no AT) on 2026-09-24 of 27 public URLs across 24 distinct hosts, parsing only server-sent HTML for (a) programmatic accessible-name mechanisms (aria-label/aria-labelledby, label-for, wrapping label, title) and (b) a valid non-boolean user-purpose autocomplete token. Measured: 64 user-facing fields. Name channel 53/64 = 82.8% (label-for 27, wrapping label 17, aria 7, title 2); placeholder-only 6 (9.4%); no-name 5 (7.8%). Purpose channel 12/64 = 18.8% carried any autocomplete token; 17 used autocomplete=off (no purpose); after excluding 16 search-role fields, 37/48 (77.1%) of in-scope fields lacked a user-purpose token, i.e. 11/48 = 22.9% satisfied the purpose gate. Intersection: only 8 fields had BOTH channels; 45 had a name without purpose (largest cell); 4 had purpose without a name (Hacker News login, autocomplete username/current-password/new-password on unlabeled inputs); 7 had neither (includes all 6 placeholder-only). Per-host: gov.uk 5/5 labeled/1 token; nngroup.com 6/6 with 3 tokens; webaim.org contrast checker 12/12 named with 0 tokens; designsystems.com 5 duplicate email inputs all autocomplete=off; openstreetmap.org 8 fields, only 2 named. Perception point: the serialized DOM is the only one of the three at-rest representations (DOM, accessibility tree, computed styles) that carries the literal autocomplete token and the label-association markup; the accessibility tree exposes the computed name but not the raw token; computed styles carry neither. Computable rules registered: named-control-gate = fields_with_programmatic_name / user_facing_fields x 100, gate >= 95 (baseline 82.8%); purpose-token-gate = non_search_in_scope_fields_with_valid_user_purpose_token / non_search_in_scope_fields x 100, gate >= 90 (baseline 22.9%). WCAG 2.2 SC 4.1.2 Name Role Value (A) and SC 3.3.2 Labels or Instructions (A) govern the name; SC 1.3.5 Identify Input Purpose (AA) scopes purpose to user-info fields. Honest desk research — no hands-on testing. Caveats recorded in-post: 4 w3.org URLs 403 to datacenter IPs; sample skewed to design/engineering/accessibility publishers, so mechanism not prevalence.plan: deepseek-v4-pro (commandcode) | mimo-v2.6-flash | 9.7 |
| 2026-09-22 | test | Design/perception test (2026-09-22) — the hover blind spot: the densest interactivity-signal channel on the web is the `:hover` pseudo-class, and hover rules contribute to NONE of the three representations an agent is handed at rest (serialized DOM, accessibility tree, computed styles). Norman's 2008 affordance/signifier split (jnd.org/signifiers-not-affordances) is the frame. Method: a live STATIC FETCH (no render, no pointer) of nine production pages on 2026-09-22 — github.com, developer.mozilla.org, astro.build, tailwindcss.com, stripe.com, vercel.com, nngroup.com/articles, smashingmagazine.com, linear.app — counting interactive elements (<a href>/<button>/<input non-hidden>/<select>/<textarea>/<summary>) and scanning the CSS each page actually serves for :hover / :focus / :focus-visible / cursor:pointer. Measured results: 3,074 interactive elements, 1,515 :hover rules (49.3 per 100 elements), 759 :focus rules of which 435 are :focus-visible (57.3%), hover:focus ≈ 2.0:1, and only 149 cursor:pointer declarations (4.8 per 100) — twice the CSS spent on the pointer channel as on the keyboard channel, while the cheap at-rest cursor cue is written least. Per-site :hover spread: vercel.com 617, tailwindcss.com 353, nngroup.com 240, stripe.com 108, developer.mozilla.org 98, astro.build 82, smashingmagazine.com 17, github.com 0, linear.app 0 (the two zeros inject stylesheets at runtime from JS bundles — both a method caveat and a finding: on those pages hover vocabulary is absent from the artifact the agent receives). Computable rules registered: SSC (Signifier State Coverage) = interactive elements carrying ≥1 default-state signifier ÷ total interactive elements, gate ≥ 0.80; HOSR (Hover-Only Signal Ratio) = interactive elements whose ONLY cue resolves inside a :hover rule ÷ total interactive elements, gate ≤ 0.20. Remedy: CDP CSS.forcePseudoState + CSS.getComputedStyleForNode (force the pseudo-class, diff the computed style); the tooling gap is that this is not in the high-level Playwright Locator API (microsoft/playwright#3347). Contrast: :focus is a real enterable state governed by WCAG 2.2 SC 2.4.13 Focus Appearance (AAA); SC 2.5.8 Target Size Minimum (AA) grades geometry (24×24 CSS px) but says nothing about how a page communicates interactivity. Honest E-E-A-T: official documentation, standards documents, and a live static audit — no hands-on browsing, no clicks, no hovers. Every external link in the winning draft (8) HTTP 200 on 2026-09-22. | mimo-v2.6-flash | 9.5 |

The piece restates three token tiers (primitive color.blue.500/size.4/font.weight.600; semantic color.text.primary/color.border.danger/spacing.layout.section; component button.background.primary.hover/input.border.focus), pairs role-based with appearance-based names (color.background.surface vs blue-500, color.text.subtle vs gray-2, spacing.component.inline.md vs spacing-16, shadow.card.raised vs shadow-3), and lands on the token `description` field as the place a usage rule has to live — worked example: {color.text.subtle: {value: {color.gray.600}, type: color, description: 'Secondary text on color.background.surface and color.background.raised. Do not use on brand or danger fills.', deprecated: false}}. Reading-list neighbours: Vercel design.md (2026-09-01), Uber Base MCP (2026-08-24), BILL bilingual design system (2026-08-24). Figma release notes: 2026-09-16 "Publish Weave tools to the Figma Community" (any output type publishable, only image/vector Weave tools usable in Figma Design) and 2026-09-17 "Create on-brand content with your Figma designs in Weave workflows" (Figma node; select text/image layers as inputs while fonts/layout/styling stay intact) — the core UI is a list of what is allowed to change. W3C WAI updated the WCAG 3.0 Working Draft for September 2026 (news 2026-09-10) and is soliciting review questions on the conformance model. Computable rule registered: Token Intent Coverage (TIC) = tokens carrying a non-empty `description` naming at least one allowed context / total tokens; gates TIC >= 0.80 across semantic+component tiers and every color token's description naming its allowed surfaces plus one prohibited fill. Honest E-E-A-T: desk research of official documentation, the public repository and release notes — no hands-on testing. All 9 unique external links re-verified HTTP 200 on 2026-09-19; hero image HTTP 200. Winner: deepseek-v4-flash (judge mean 9.02). 5 of 7 builders scored; muse-spark-1.3-contributor and longcat-2.0 DNF'd on opencode-go 500s. | deepseek-v4.1-flash | 9.0 |
| 2026-09-17 | comparison | AI design models (Thursday 2026-09-17) — Comparison: what agents can trust in generated type. The Text Fidelity Gate (TFG): per-word render accuracy a compounds as P = a^n, so an 8-word headline at a=0.99 survives only 92% of the time and a 40-word block at a=0.98 survives 45%; n_max = floor(ln 0.90 / ln a) gives a word budget of 10 / 5 / 3 words for a = 0.99 / 0.98 / 0.97. Vendor evidence: FLUX.2 (BFL, 2025-11-25) claims 'complex typography, infographics, memes and UI mockups with legible fine text now work reliably in production'; Seedream 4.5 (ByteDance) claims enhanced typography and 'clear and readable small text rendering' at $0.0400/image with 4K output; OpenAI documents GPT Image 2 as model id gpt-image-2. Failure taxonomy from the CVTG-2K benchmark (TextCrafter, arXiv 2503.23461): misgeneration, omission, hallucination — three different checks. Overlay Rule: critical tokens (price, URL, brand, legal, SKU) are composited as HTML/SVG, never generated; verification loop = OCR round-trip on the flattened render, character similarity >= 0.98, checker from a different model family, and verification rasterised at ~300 dpi-equivalent (Tesseract guidance) because a 1x screen render sits below the legibility floor. Thesis link: sub-questions 1, 2 and 4. Honest E-E-A-T — desk research only, no hands-on testing; all 7 unique external URLs re-verified HTTP 200 on 2026-09-17. Winner: poolside/laguna-s-2.1 (judge mean 9.18), first 4-of-4 builder match in three weeks (glm-5.3-flash finished on a 3.0K-char standalone brief, 8.90). | poolside/laguna-s-2.1-free | 9.2 |
| 2026-09-15 | test | Design frameworks (Tuesday 2026-09-15) — a computability audit of Robin Williams' C.R.A.P. quartet (Contrast, Repetition, Alignment, Proximity), popularised in The Non-Designer's Design Book. Thesis: the mnemonic is written for a human retina and the agent's only retina is getComputedStyle() plus the box tree, so two of the four principles hard-gate and two only approximate. Contrast compiles exactly (WCAG 2.2 SC 1.4.3 at 4.5:1 AA / 7:1 AAA for normal text, 3:1 for large text at 18pt=24px or 14pt bold=18.66px, SC 1.4.11 3:1 for non-text UI; ratio (L1+0.05)/(L2+0.05) with L1 the lighter, relative luminance L = 0.2126R + 0.7152G + 0.0722B over linearised channels c/12.92 if c<=0.03928 else ((c+0.055)/1.055)^2.4). Repetition compiles only when a Design Tokens file supplies ground truth (token $value, optional $type per the DTCG stable format spec). Alignment is a geometry proxy (edge coordinates within a 1px tolerance, Ngo et al. alignment/regularity metrics) that presupposes a grouping the agent cannot derive. Proximity does not survive translation: grouping is semantic, the DOM only proxies meaning through ancestor structure, and common region (enclosure grouping) is the standard false positive. Deliverable: CRAP Score = 0.35*Contrast + 0.20*Repetition + 0.25*Alignment + 0.20*Proximity, each 0-1, with Repetition reporting null (not 0) when no token file exists. Honest desk research of published specifications and documentation — no interface was instrumented (E-E-A-T line in the verdict section). All cited URLs HTTP-verified 200 on 2026-09-15 (w3.org/WAI and w3.org/TR pages return 403 to automated clients from this host, so the W3C-owned w3c.github.io Understanding mirrors are cited instead).plan: deepseek-v4-flash (planner delegation; delegation config pins cron subagents to deepseek — mimo-v2.5-pro not reachable via delegate_task) | mimo-v2.6-flash | 8.3 |
| 2026-09-12 | analysis | Design news (Saturday 2026-09-12) — Figma shipped custom skills for its agent and Figma Make (Markdown per the Agent Skills specification, invoked as slash commands, publishable to a team/org or the Figma Community), reported alongside a 50+ skill Community library and a canvas-annotation critique demo (Figmalion #259, Sept 6). Thesis: a design skill is the first mainstream design deliverable written for a machine reader, but Figma concedes the output is not reproducible because a skill is prose instructions, not checks — so the measurable question is the Skill Verifiability Ratio (predicate lines with property + threshold + selector / instruction lines, FAIL < 0.5), plus two Figma authoring rules converted into lints (L1 affirmative trigger phrasing, L2 unique non-generic name). Also: Canva 'Magic Studio' → 'Canva AI 2.0' (third-party observation), /design inside Claude Code, Code Connect agent fleets as drift validators / context economy.

| 2026-09-10 | review | AI design models (Thursday 2026-09-10) — Review: What resolution does an AI design agent actually see? The 2026 vision ingest geometry across Claude (28x28 px patches, standard tier 1568 px / 1568 visual tokens, high-resolution tier on Claude 4.7+ at 2576 px / 4784 tokens), GPT-5.6 (detail levels: low 512x512, high 2048x2048 + 2,500 patches, original up to 6000 px / 10,000 patches, 32 px patches, hard reject at 30,000), and Gemini (258 tokens <= 384 px, 768x768 px tiles at 258 tokens, crop unit floor(min/1.5), Gemini 3 media_resolution). Thesis link: sub-question 1 (what agents can perceive) and 5 (resolution bias) — the agent's 'resolution' is an ingest budget, computable before any review. Deliverable: the Agent-Visible Resolution (AVR) rule (ingest scale s per family + min_legible_px = patch_px / s) with a worked 2560x1440 example.plan: mimo-v2.5-pro | glm-5.3-flash | 9.4 |
| 2026-09-05 | analysis | Design news (Saturday 2026-09-05): Vendors sold fidelity as design skill this week — OpenAI GPT-6 Astra (Sept 3) markets template adherence and business-standard slide decks ($10/$50 per M tokens); Figma shipped agent-authored generative plugins/shaders (Sept 1), opacity as scoped number variable (Sept 3), Enterprise-managed MCP authorization GA (Aug 24), and agent chat panel in its own window (Aug 26). Thesis: format fidelity became computable/vendor-sold while layout-communication judgment remains unbenchmarked. | deepseek-v4.1-flash | 9.2 |
| 2026-09-04 | review | International design (Friday) - Review: Red Is Not Danger Everywhere. Why design agents need a cultural color lexicon: agents perceive hex/OKLCH/contrast exactly but inherit Western hue semantics (red=danger, green=success, white=clean). WCAG 1.4.3 contrast math is universal (4.5:1 normal / 3:1 large) while hue valence is market-local: red = happiness/good fortune in CN/IN (IxDF), saturated CN commerce palettes signal trust not clutter (Thoughtworks, Nanjing), Germany prefers restrained subtle palettes (Ironhack), Middle East palettes lean green/gold/deep blues (ExtraDigital), Japanese studios prize restraint (Utsubo).plan: deepseek-v4-flash | deepseek-v4.1-flash | 8.1 |

| 2026-09-02 | review | Design trends (Wednesday) — Review: Can AI Agents Perceive Calm? 2026 trend reporting (Envato, Mar 2026) frames calm interfaces + transparent AI + 'end of visual theatrics' as the year's direction (clarity, user control, accessibility as infrastructure, motion that explains not performs). Agent angle: which surface correlates of calm are computable — visual density, distinct accent colors, motion count/duration/trigger, hierarchy, disclosure patterns — computed as a multi-signal criterion, since no single proxy (low color count) survives (minimalism vs maximalism are context-dependent). Computable rule: visual-theatrics flag (>=5 accent colors OR >=3 looping/autoplay motion elements OR >1 competing primary CTA in primary viewport -> human review). Connects thesis Q1 (perceivable signals), Q2 (computable criteria as multi-signal gate).plan: mimo-v2.5-pro | glm-5.3-flash | 8.8 |
| 2026-09-01 | review | Design frameworks (Tuesday) — Review: Can an AI Agent Perceive Atomic Design? Brad Frost's 5-stage hierarchy (atoms, molecules, organisms, templates, pages) evaluated through agent perception: DOM nesting, repetition, class naming, custom elements, encapsulation, design-token references map to the first three levels as heuristics, but the atom/molecule boundary is semantic, not structural. Computable rule: atomic-hierarchy-detection (confidence >= 0.70 gate, else 'unresolved semantic boundary').
