v0.23.0

[0.23.0] - 2026-02-19

Changed

• Replaced Bulma CSS framework with a custom ht- prefixed design system featuring cool slate surfaces, warm amber accent, and Space Grotesk + JetBrains Mono typography (#262)
• Extracted all design tokens into tokens.css with [data-theme] selector support for future theming (#262)
• Redesigned dashboard with app status chip grid, activity timeline, and streamlined layout (#262)
• App detail pages now use a flat single-page layout with collapsible metadata, inline tracebacks, and instance switcher dropdown (#262)
• Bus listener and scheduler job tables show expanded detail rows with predicate, rate-limiting, and trigger information (#262)
• Replaced hardcoded CSS fallback colors in alerts and detail panels with proper design tokens (--ht-surface-inset, --ht-surface-code, --ht-warning-*, --ht-danger-*)
• Toggle buttons now show fallback text before Alpine.js initializes and expose aria-expanded for accessibility (#262)
• E2E tests now run by default with uv run pytest instead of requiring -m e2e; added nox -s e2e session for CI
• HassetteHarness now uses a fluent builder API (with_bus(), with_state_proxy(), etc.) with automatic dependency resolution instead of boolean flags (#253)
• Consolidated duplicate mock Hassette, DataSyncService, and web test helper fixtures into shared factories in test_utils/ (#253)
• All test helper functions now exported from hassette.test_utils public API; tests import from the package instead of submodules (#253)
• Replaced 28 asyncio.sleep() synchronization calls across 8 integration test files with wait_for polling helper for deterministic, faster tests (#253)
• Renamed create_mock_hassette() to create_hassette_stub() and mock_hassette.py to web_mocks.py to clarify web/API stub vs harness distinction (#259)
• Added autouse cleanup fixtures for bus, scheduler, and mock API to prevent test pollution in module-scoped fixtures (#256)

Fixed

• WebSocket service now fires disconnect event and marks not-ready immediately on unexpected connection loss, preventing stale state in StateProxy (#270)
• App detail page now uses the actual instance index instead of hardcoded 0, fixing data/URL desync for non-zero instances (#262)
• Detail panel labels now have proper text contrast on dark --ht-surface-code background (#262)
• Collapsible panels and tracebacks no longer flash visible before Alpine.js initializes (#262)
• Entity browser "Load more" button now appends rows instead of replacing existing ones on domain-filtered views (#247)
• model_dump() and model_dump_json() on AppManifest and HassetteConfig no longer leak extra fields (e.g. tokens from environment variables)

Added

• supports_* boolean properties on light, climate, cover, fan, media_player, and vacuum attribute classes for checking entity capabilities without manual bitmask operations (#272)
• IntFlag enums (LightEntityFeature, ClimateEntityFeature, etc.) matching Home Assistant core feature flags (#272)
• Global alert banner showing HA disconnect warnings and failed app errors with expandable tracebacks (#262)
• ht-btn--ghost and ht-btn--xs button modifier classes (#262)
• extras property and extra() helper on BaseState and AttributesBase for safe access to integration-specific attributes (#271)
• JSDoc comments across all web UI JavaScript files (#251)
• ESLint linting, TypeScript type-checking, and mise run lint:js / mise run typecheck:js tasks (#251)

Removed

• Bulma CSS CDN dependency (#262)
• Entity Browser page and related partials (#262)
