Armature — v0.6.x UI Hardening Roadmap

Goal: Fix all viewport scaling, banner integration, and styling inconsistencies so Claude Code can run a meaningful automated usability survey against a stable, uniform UI.

Problem Inventory

P1 — Viewport & Scaling (blocks everything)

#	Issue	Where	Impact
1	Dual layout systems — base.html template has its own banner→surface→footer column; app-shell.js Preact shell has a separate sw-shell → sw-shell__body → sw-shell__surface column. They never coordinate.	server/pages/templates/base.html ↔ src/js/sw/shell/app-shell.js	Every surface inherits an ambiguous viewport ancestor.
2	Transform-based scaling is broken — transform: scale() on #surfaceInner doesn't reflow layout. Breaks getBoundingClientRect (menu.js already carries a scale-correction hack at line 20), scroll containment, pointer events, and the inverse-width/height hack (100/s%) doesn't account for banners consuming viewport space.	base.html:56-67, appearance.js:41-53, menu.js:20-33	Menus, tooltips, dropdowns all mis-positioned at any non-100% scale. Click targets wrong.
3	Banner height desync — base.html hardcodes --banner-h: 28px and renders banners in-flow. app-shell.js ShellBanner measures offsetHeight into --banner-top-height / --banner-bottom-height and uses position: fixed + body padding. Two independent banner systems.	base.html:31,72-75,103-107 ↔ app-shell.js:25-42, sw-shell.css:22-37,63-69	With banners enabled, content overflows by the banner height or gets double-inset depending on which code path is active.
4	100vh on mobile — .sw-shell, .chat-app, .chat-loading, .login-shell use 100vh which doesn't subtract mobile browser chrome (address bar, toolbar).	sw-shell.css:9, chat/css/main.css:15,25, sw-login.css:7	Content overflows on iOS Safari, Android Chrome.
5	Chat uses 100vh not 100% — .chat-app { height: 100vh } ignores parent container (which already excludes banners/footer). Notes correctly uses height: 100%. Every extension surface that copies chat's pattern will inherit the bug.	packages/chat/css/main.css:15	Chat surface overflows behind banners.

P2 — CSS Architecture

#	Issue	Where	Impact
6	Class name collisions — .settings-section defined in both modals.css:41-43 and surfaces.css:75-83 with different padding, margin, and border-bottom rules. .sw-dropdown in primitives.css:443 (styled <select>) vs sw-primitives.css:262 (custom dropdown component). .sw-tabs in primitives.css:459 vs sw-primitives.css:234.	Kernel CSS	Styles randomly win depending on load order. Bug reports differ by surface.
7	Old/new primitive duplication — Two button systems (.btn-primary/.btn-small in primitives.css vs .sw-btn--primary/.sw-btn--sm in sw-primitives.css). Two toast systems (.toast vs .sw-toast). Two dropdown, two tabs implementations.	primitives.css ↔ sw-primitives.css	No single source of truth for any component. Extension authors can't know which to use.
8	Extension CSS bleeds globally — Extension main.css loaded via <link> at document level, no scoping. Any class name can override kernel or sibling extension styles.	base.html:26-28, extension-surface.css	Package CSS fights with kernel. Two packages with .sidebar both lose.
9	No intermediate breakpoint — Only 768px mobile breakpoint. No tablet (768–1024px). Secondary workspace pane hardcoded 480px. Admin nav hardcoded 200px.	layout.css:263, surfaces.css:305	Cramped layout on iPad/small laptops.

P3 — Visual Consistency

#	Issue	Where	Impact
10	Mixed unit systems — px, rem, em used interchangeably with no rationale. Some font-sizes in px (primitives), others in rem (sw-primitives), others in em (user-picker).	All CSS files	Zoom/scale behaves differently per element.
11	Google Fonts CDN dependency — @import url(...) in variables.css:5 blocks rendering if CDN is slow; breaks entirely on air-gapped deployments.	variables.css:5	FOUT or blank page on slow networks. No offline support.
12	No spacing scale — Padding/margins are ad-hoc values (10px, 12px, 14px, 16px, 20px, 24px, 28px…). No design-token spacing scale.	All CSS	Inconsistent visual rhythm across surfaces.
13	Hardcoded fallback colors in component CSS — sw-shell.css, sw-primitives.css have inline fallbacks like var(--accent, #b38a4e) — a gold color from a previous theme that doesn't match the current blue #6c9fff.	sw-shell.css, sw-primitives.css	Wrong colors flash briefly if variables load late.

Roadmap

v0.6.9 — Session Lifetime Config ✅

Shipped. Admin-configurable TTLs, "keep me logged in" checkbox, idle timeout, config-driven generateTokens(), 7 new tests. See CHANGELOG.md for details.

v0.6.10 — Viewport Foundation ✅

Shipped. Single layout model: body → shell → surface. CSS zoom replaces transform: scale(). 100dvh fallbacks everywhere. Extension surfaces use 100% instead of 100vh. Dead shell layout code deprecated. See CHANGELOG.md.

v0.6.11 — CSS Deduplication ✅

Shipped. Old primitive system retired. One class per concept. See CHANGELOG.md.

Step	Description
Audit collision inventory	Script that finds all duplicate class selectors across kernel CSS files. Produce a machine-readable collision report (JSON).
Migrate .settings-section	Remove modals.css:41-43 definition. The surfaces.css definition is authoritative. Modals that used the old styles get explicit overrides scoped to .modal .settings-section.
Retire primitives.css old components	.btn-primary, .btn-small, .btn-danger, .btn-full → migrate all usages to .sw-btn--*. .toast-container / .toast → migrate to .sw-toast-container / .sw-toast. Old .popup-menu → migrate to .sw-menu. Old .sw-dropdown (styled select in primitives.css) → rename to .sw-native-select or delete if unused. Old .sw-tabs / .sw-tab-btn in primitives.css → delete (sw-primitives.css version is authoritative).
Mark deprecated classes	Any remaining old classes get a /* DEPRECATED v0.6.11 — use .sw-btn--* */ comment and a 1-version grace period for package authors.
Package CSS audit	Scan all packages/*/css/main.css for references to deprecated kernel classes. Fix in-tree packages.

v0.6.12 — Extension CSS Isolation ✅

Shipped. Prefix enforcement via linter. All 12 in-tree packages migrated. See CHANGELOG.md.

Step	Description
Scoping strategy	Prefix enforcement (option B). @scope support still patchy; prefix works everywhere, trivially lintable.
Linter	scripts/lint-package-css.sh — validates first class selector in every rule starts with .ext-{slug}. Exempts :root, @keyframes, @font-face, @media, .sw-* kernel classes, .cm-* CodeMirror classes.
Kernel CSS contract	docs/EXTENSION-CSS.md — stable public classes (.sw-btn--*, .sw-input, .sw-field, .sw-dialog, .sw-toast, .sw-menu, .sw-tabs, etc.) and all CSS variables. Everything else internal.
Migrate in-tree packages	data-ext="{{.Surface}}" on extension mount. All 12 packages prefixed to .ext-{slug}-*. CSS + JS updated in lockstep.

v0.6.13 — Responsive & Spacing ✅

Shipped. Spacing token scale (--sp-1 through --sp-12, 4px grid) in variables.css. Tablet breakpoint (max-width: 1024px) in layout, surfaces, login. All kernel CSS and 12 in-tree packages migrated to spacing tokens. EXTENSION-CSS.md updated with spacing table and breakpoint guide. Font-size scale deferred to v0.6.14. See CHANGELOG.md.

v0.6.14 — Visual Polish ✅

Shipped. Stale fallback colors purged (~65 instances), fonts self-hosted (DM Sans + JetBrains Mono woff2), border-radius standardized to three tokens (--radius-sm, --radius, --radius-lg). Also fixed v0.6.13 spacing regressions (half-step tokens), theme settings default, surface overflow, and user menu zoom drift. See CHANGELOG.md.

v0.6.15 — User Display Audit ✅

Shipped. GET /api/v1/users/resolve?ids=... batch endpoint, sw.users SDK module with resolve(), resolveMany(), displayName() + 60s cache. Chat participants resolved from users table instead of snapshot. All admin surfaces show display_name || username || 'Unknown'. Chat-core snapshot column deprecated. 5 new handler tests. See CHANGELOG.md.

v0.6.16 — Usability Survey Gate ✅

Shipped. Four audit scripts, structured survey prompt, contrast/touch-target fixes, Docker docs corrected. All 48 contrast pairings pass, all close buttons have 44px mobile targets, focus-visible on all key primitives. See CHANGELOG.md.

What "Usability Survey by Code" Means

The v0.6.16 deliverables give Claude Code (or any automated tool) three things:

1. A structured inventory (ui-inventory.json) of every component, on every surface, with its CSS file and line number.

2. Automated checks (contrast, touch targets, token usage) that produce machine-readable pass/fail reports.

3. A survey prompt (USABILITY-SURVEY.md) with explicit criteria and file paths, so Claude Code can cat the relevant files, run the scripts, and produce a scored report without human guidance.

The survey is not a substitute for real user testing — it's a structural quality gate that catches the class of bugs (overflow, contrast, misalignment, inconsistent styling) that have historically slipped through.
