feat(status): per-browser dismissal for Recent Incidents

The Recent Incidents list is derived server-side from raw AppStatus health-check samples, so there is no incident row to delete and deleting the underlying samples would corrupt uptime % and the sparkline timeline. Per-browser, non-destructive dismissal is the right model: localStorage holds the dismissed (appId, ISO startedAt) keys, the page filters them out on render, and a Restore affordance brings them back. - Per-row Dismiss (X) and section-level Clear all - Restore link appears whenever any incident on the current page is hidden - Dismissal key is (appId, startedAt) so it survives 24h/7d/30d switches - Focus is moved to the Restore link after Clear all empties the list (otherwise the unmounting button would drop focus to <body>) - Quota / disabled-localStorage failure is swallowed; in-memory state still works for the active session Hand-rolled <button> elements match 14 other link-styled buttons already in the project; both use the project-standard focus-visible:ring-2 focus-visible:ring-primary/30 ring.
feat(backup): harden restore — strict tar, two-phase rollback, degraded state

+# web-app-launcher — project guide for Claude
+
+SvelteKit 2 + Svelte 5 (runes) + Tailwind 4 + Prisma + Vitest. Cozy Home design system (warm cream / dusk, terracotta accent, Fraunces + Figtree, soft shadows). Token contract lives in `src/app.css`.
+
+## Frontend
+
+### Basic-component reuse — MANDATORY
+
+When you need any of the following, **use the existing primitive from `src/lib/components/ui/`. Do not hand-roll a new Tailwind class string for a control that already has a primitive.**
+
+| Need | Primitive | Why |
+|---|---|---|
+| Boolean on/off setting | `Switch.svelte` | Pill toggle, `role="switch"`, AA contrast, terracotta track when on. Default for any "enable X" / "show Y" / "is default" field. **Never use `<input type="checkbox">` for booleans.** |
+| Multi-select item in a list | `Checkbox.svelte` | Rounded square with animated check-draw. Only use when the control is truly "pick any number of these," not a single boolean. |
+| Dropdown of fixed options | `Select.svelte` | Styled chevron, matches Cozy input radius. Wraps native `<select>`. **Do not use raw `<select>`.** |
+| Single-line text / number / email / url / password | `Input.svelte` | Standard rounded-xl, focus ring, invalid state. **Do not repeat the `w-full rounded-xl border border-input bg-background px-3 py-2 ...` string anywhere.** |
+| Number in a range (refresh interval, hue, blur, etc.) | `Slider.svelte` | Cozy gradient track, terracotta-bordered knob, value tooltip, `aria-valuetext`. **Do not use raw `<input type="range">`.** |
+| Action button (submit, save, cancel, link-as-CTA) | `Button.svelte` | Variants `primary | secondary | outline | ghost | destructive`, sizes `sm | md | lg | icon`, built-in `loading` spinner, press-squash. **Do not repeat `rounded-xl bg-primary px-4 py-2 ...` strings.** |
+| Label + hint + error wrapper around a control | `Field.svelte` | Consolidates `<label> + control + <p class="text-xs text-destructive">`. |
+| Confirm-before-destructive | `ConfirmDialog.svelte` | Already exists. Use it. |
+| Entity / icon / tag picker | `EntityPicker`, `MultiEntityPicker`, `IconPickerButton`, `TagsInput` | Already exist. Reuse. |
+
+### Process
+
+1. Before writing any form control in a `.svelte` file, **scan `src/lib/components/ui/` first**. If a matching primitive exists, import and use it.
+2. If you find yourself copying a Tailwind class string verbatim from another file, **stop**: that's the trigger to extract a primitive (or expand an existing one).
+3. If you genuinely need a new primitive, add it to `src/lib/components/ui/`, give it a `class?: string` prop merged via `cn()`, document it in this table, and migrate at least two call sites in the same PR so it's not dead code.
+4. Tokens (`--primary`, `--card`, `--room-*`, `--shadow-soft`, etc.) are defined once in `src/app.css`. Never hardcode hex/HSL — read from the token.
+
+### Cozy spec quick reminders
+
+- Hero cards: `rounded-[1.4rem]` + `shadow-[var(--shadow-soft)]`. Dense panels: `rounded-xl`. **Never** `rounded-lg` on a section wrapper.
+- Headings (`h1`, `h2`, `h3`) automatically get Fraunces via base layer — no need to add `font-display` unless overriding non-heading text.
+- Focus uses `focus-visible:ring-2 focus-visible:ring-primary/30` — primitives already do this; mirror it on anything hand-rolled.
+- Motion is gentle and present: prefer `cozy-rise` / `cozy-expand` from `app.css` over generic Tailwind animations. All motion classes already respect `prefers-reduced-motion`.
+
+## Backend
+
+- Auth: session cookie + optional OAuth. Roles: `admin` / user / guest. Always check role at the route load function, not the component.
+- Validation: Zod schemas live in `src/lib/utils/validators.ts`. Reuse the same schema on client (superForms) and server.
+- DB: Prisma. Never query the DB directly from a route — go through `src/lib/server/services/*Service.ts`.
+
+## Testing
+
+- Vitest, Node environment, no DOM (existing pattern). Component tests use the module-scope helpers (e.g., `buttonClass` in `Button.svelte`) rather than rendering — keep that convention.
+- Run before committing: `npm run check && npm run lint && npm test && npm run build`.
+
+## Commands
+
+```bash
+npm run dev      # vite dev on :5181
+npm run check    # svelte-check (TS + Svelte)
+npm run lint     # eslint
+npm test         # vitest run
+npm run build    # production build
+```

alexei.dolgolyov	16c667ca15	feat(status): per-browser dismissal for Recent Incidents The Recent Incidents list is derived server-side from raw AppStatus health-check samples, so there is no incident row to delete and deleting the underlying samples would corrupt uptime % and the sparkline timeline. Per-browser, non-destructive dismissal is the right model: localStorage holds the dismissed (appId, ISO startedAt) keys, the page filters them out on render, and a Restore affordance brings them back. - Per-row Dismiss (X) and section-level Clear all - Restore link appears whenever any incident on the current page is hidden - Dismissal key is (appId, startedAt) so it survives 24h/7d/30d switches - Focus is moved to the Restore link after Clear all empties the list (otherwise the unmounting button would drop focus to <body>) - Quota / disabled-localStorage failure is swallowed; in-memory state still works for the active session Hand-rolled <button> elements match 14 other link-styled buttons already in the project; both use the project-standard focus-visible:ring-2 focus-visible:ring-primary/30 ring.	2026-05-28 15:40:23 +03:00
alexei.dolgolyov	dab13518ef	feat(backup): harden restore — strict tar, two-phase rollback, degraded state - Gate flag flipped synchronously in restore route before body parse, closing race where concurrent requests could slip through during awaits - Strict tar extraction rejects symlinks, hardlinks, absolute paths, and parent-segment traversal entries - Staging directory moved to a sibling of the uploads dir so atomic renames stay on the same filesystem (Windows %TEMP%/Linux tmpfs were causing EXDEV) - Two-phase atomic-rename rollback for uploads — never rmrf the live dir before the safety is back in place; degraded flag set if rollback can't recover cleanly - Prisma reconnect failure now marks process degraded; hooks.server.ts returns 503 to everything except /api/health so orchestrators can recycle - /api/health distinguishes ok / restoring / degraded / db_down (503s) - Legacy .db restore now runs structural SQLite integrity check before swap - Schema-version check tightened: null on either side requires explicit allowSchemaMismatch override (was silently treated as a match) - HMR/multi-import-safe global state (Vite dev reload no longer creates a fresh module while a restore is mid-flight) - VACUUM INTO path: defensive rejection of quote/control characters - Backup filename regex requires a leading alphanumeric (rejects '.tar.gz', '....db' which passed the previous loose pattern) - Download: RFC 5987 Content-Disposition with filename* + sanitized fallback - Restore route logs BACKUP_FAILED audit row with phase on failure	2026-05-28 14:56:57 +03:00
alexei.dolgolyov	f087551454	feat(ui): cozy polish — primitives, motion, empty states Adds 7 reusable primitives in src/lib/components/ui/ and migrates ~70 hand-rolled call sites across forms, admin panels, and routes. Tokens unchanged — same Cozy Home palette, just consistently applied. Primitives - Switch: pill toggle, role=switch, terracotta track, cubic-bezier knob - Button: 5 variants × 4 sizes, press-squash, loading spinner, buttonClass() helper for <a> link-as-CTA cases - Checkbox: rounded square with animated check-draw + indeterminate - Select: native <select> with Cozy chevron + matched radius - Slider: gradient track, terracotta-bordered knob, aria-valuetext - Input + Field: documented in CLAUDE.md for future use - 9 buttonClass unit tests Migrations - 23 <input type=checkbox> → <Switch> (boolean settings) - 5 multi-select checkboxes → <Checkbox> (DiscoveryPanel, sys-stats metrics) - ~28 <select> → <Select> - 17 <input type=range> → <Slider> (ThemeCustomizer's hue picker kept custom) - ~25 hand-rolled buttons → <Button> / buttonClass() Surface polish - Admin section wrappers: rounded-lg → rounded-[1.4rem] + shadow-soft (resolves the Phase-5 tradeoff from the Cozy migration memo) - BoardPropertiesPanel: live theme preview swatch showing computed hsl() on a sample button; hue/sat use Slider; bg/cardSize use Select - AppHealthBadge: role=status + aria-live=polite; .status-degraded (slow amber breathing) and .status-offline (single attention flash) now applied - AppForm collapse triggers: rotating chevron + aria-expanded - Empty states for /boards and /apps: inline SVGs using --room-* tokens (peach/sky/sage/butter) instead of generic Lucide icons - Login Remember Me: showcase Switch (first-impression surface) Motion (src/app.css) - New cozy-rise / cozy-rise-stagger for staggered grid reveals (/boards, /apps) - New cozy-expand for accordion sections (healthcheck, integration, wallpaper) - All motion respects prefers-reduced-motion CLAUDE.md - New project guide with a mandatory Frontend reuse table — every primitive documented with "never use raw <input type=checkbox>/<select>/<range>" and "do not repeat rounded-xl bg-primary px-4 py-2 ..." rules Verification - npm run check: 0 errors, 0 warnings, 5831 files - npm test: 301 passing - npm run lint: 0 errors (19 pre-existing warnings unchanged) - npm run build: ✔ done Branch is feat/cozy-polish, ready to PR against master.	2026-05-28 14:39:53 +03:00
