Release · July 1, 2026 · v0.6.55

What's new

Jul 1 (0.6.55) hardens agent discipline when screenshots are attached: exxat-image-ia-gate records the upload on submit; exxat-brief-gate escalates with IA-only + brief-first messaging on the next design-critical write. Onboarding step 1 hides sidebar and site header; step 2+ shows a live preview. Typography fixes darken --muted-foreground, keep helpers at text-sm, and drop muted opacity hacks on nav and breadcrumbs. Jun 30 (0.6.53) shipped the 978/978 axe gate, ScrollRegion primitives, and Google Antigravity .agents/ mirror — still the accessibility floor on every upgrade.

0 · Agent context + onboarding · 0.6.55

Screenshots are IA — not pixels.

Uploaded mockups inform information architecture only. The new beforeSubmitPrompt hook writes a short-lived flag when a turn includes an image; the brief-gate then appends an IA-only escalation on the next design-critical write — so agents cannot silently pixel-copy chrome. Constitution + ux-discovery rules carry the same mandate; exxat-ui doctor smoke-tests the pipeline end-to-end.

Step 1 is focus mode

Sidebar and site header hidden on the welcome step; breadcrumb chrome returns from step 2 with a live nav preview.

Welcome to Design OS

Onboarding title reads as Design OS — not a generic product welcome. Ivy wordmark on the sidebar B2 lockup uses font-heading.

Readable meta copy

--muted-foreground darkened; helper/description text stays text-sm; nav and breadcrumb opacity hacks removed.

Release gates enforce parity

pnpm release:gates runs agent:context:validate — hooks, rules, and Claude mirrors must match before publish.

0a · Accessibility ship · 0.6.53

978 scans. Zero violations.

The ship matrix runs 163 routes × six variants (desktop light/dark, Windows high contrast, reflow-320) with axe-core + Playwright. Pass means zero WCAG 2.x AA violations — not a Lighthouse spot-check on one page. Fixes belong in packages/ui primitives so every consumer inherits them on upgrade.

pnpm a11y:axe:all --variants ship pnpm a11y:axe:report ScrollRegion HorizontalScrollViewport BadgeAi · Badge prompt .agents/ Antigravity mirror

Component-level fixes

scrollable-region-focusable and color-contrast failures resolved in shared scroll + badge chrome — not per-route doc previews.

Markdown receipts

Every gate run writes axe-a11y-summary.json + axe-a11y-report.md under .axe-reports/.

Inline agent workflow

Accessibility skills run axe + read the report in the main agent — no sub-agent dispatch.

Antigravity parity

pnpm sync-antigravity mirrors Cursor rules/skills to .agents/ with slash-command workflows.

I · Hub table filters

Every column can filter.

Before 0.6.50, only columns with an explicit filter: block appeared in Add filter. Now cellKind on each column definition drives the filter type — person, status, rating, progress, currency, numeric range, date range, or text — and the toolbar chips use the same runtime as Table properties.

filterableColumns() resolveColumnFilter filterFieldContext FilterPersonOptionList FilterRangeControl FilterDateRangeControl
Column types hub filter demo (light mode) Column types hub filter demo (dark mode)
Library hub with filter toolbar (light mode) Library hub with filter toolbar (dark mode)

Add filter lists all columns

Data columns with a cellKind show up even when you never wrote a filter: block.

Person pickers from row data

derivePersonFilterOptions builds the avatar list from the hub dataset — not a hard-coded mock array.

Chips match Properties

Range sliders, date windows, and rich option previews in the toolbar mirror the Properties sheet controls.

One filter bag

Table, list, board, and dashboard views read the same useTableState filters — change once, every view follows.

II · Component catalog

Live hub previews — not sandboxes.

The dogfood catalog split into list + details. Hub primitives (DataTable, KPI strip, board cards) render the same reference tables you ship in Library — including the column-types rule demo at /column-types-demo. Side panels use FloatingSheetPanel (no overlay bleed, no sharp-corner Sheet chrome).

List + details IA ColumnTypesRuleDemoTable FloatingSheetPanel Reversed category order

III · Exam lock · 0.6.50

Assessment delivery — no hub chrome.

Timed exams are not list hubs. ExamLockTemplate owns the full viewport: brand bg-sidebar canvas, inset question card, transparent app header (title, timer, tools, avatar), and card-top progress. App.tsx omits sidebar, ⌘K, Ask Leo, and system banner on /exam-lock.

ExamLockTemplate MCQ · T/F · fill-blank · essay Stem figures + image zoom Color mode toggle Submitted confirmation

Question renderer

One switch routes stem + body by type — shared nav, progress, and keyboard submit.

Native figure dialog

Stem images open in <dialog> with DS tokens — not a bespoke modal stack.

Enter / Esc parity

Submit and cancel pair inline Kbd hints with <Shortcut> bindings.

Showcase route

/design-os/exam-lock demos the full delivery loop for design review and QA.

Focus ≠ hub (P9)

Do not put exam delivery inside ListPageTemplate. Register suffixes in lib/exam-lock-shell.ts; agents load exxat-focus-workflow before authoring.

IV · Focus workflow · 0.6.50

One task — sidebars off.

Create-question and short compose flows use FocusWorkflowTemplate: primary + secondary sidebars hidden via isSidebarHiddenPath, but ⌘K and Leo stay available unless the product opts out. Reference: /library/new and /design-os/focus-workflow showcase.

V · Library secondary panel · 0.6.49

Folder labels wrap.

Long folder names in the Library scope rail no longer truncate or overlap the next row. Rows use h-auto min-h-8 with top-aligned chrome; the active highlight grows with the label. On /library/new, the focus shell keeps a compact icon scope rail while the primary sidebar is hidden.

Library secondary panel with wrapped folder tree labels

Primary + secondary rails

Expanding the main sidebar while a scope rail is open collapses the secondary panel to its icon strip — both rails no longer fight for width on narrow laptops.

VI · Column cell primitives

Pick the right cell — and filter.

The table-column-cells pattern now documents which primitive belongs on each data point — person avatar column, status badge, progress bar, currency, rating — and how each cellKind wires into filters. Agents load exxat-table-column-cells instead of inventing bespoke filter markup.

Person columns

Avatar + name + email in tables; filter picker lists people from the hub rows.

Status + badge columns

Shared list-status badges; filter dropdown matches chip vocabulary.

Progress + rating

ProgressCell and star ratings filter as numeric ranges — not free-text search.

Date + currency

Date-range control and numeric bounds reuse the same toolbar chip shell.

VII · Agent context shipped

Rules + skills for tables.

table-column-cells-pattern.md, focus-workflow-pattern.md, exxat-table-column-cells.mdc, exxat-focus-workflow.mdc, and consolidated skills (exxat-kpi, exxat-overlays, exxat-sidebar-nav) sync to consumer apps via exxat-ui sync-extras. When a PM asks for a placements column or an exam screen, the agent maps to documented templates — not a one-off div stack.

exxat-table-column-cells skill exxat-data-tables rule consumer-extras mirror 50 binding rules 28 AI skills

What this means in review

Filter chips, person pickers, and column types should match Library reference — agents cite apps/web/docs/table-column-cells-pattern.md and the hub table in library-table.tsx, not screenshots pasted into chat.

VIII · Polish & fixes

Small things that blocked.

Slider thumbs no longer remount mid-drag (key={index} on thumbs). Dev toolchain deps patched (vite, vitest, hono, ws) via pnpm overrides — no runtime API change, cleaner Dependabot posture.

Slider drag fix

Catalog range demos and Properties sliders stay draggable end-to-end.

No raw Sheet in catalog

Side panels demo FloatingSheetPanel — matches production overlay rules.

React Doctor 100

Reference app clears react-doctor warnings on filter + catalog surfaces.

Still no toasts

Feedback stays on banners, inline status, and dialogs — Sonner remains gone.
