| N105 | Notification clicks work after tab close (SW `notificationclick` + `showNotification`) | `sw.ts`, `utils/dom.ts`, `ClientNonUIFeatures.tsx` | get a msg notif, close the tab, click it → app focuses/opens + routes to the room |
**Verified working in live testing (2026-06):** A2, B1–B4, C1, C3, D (mic/camera/deafen/screenshare/fullscreen/more-menu/PiP). Denoise quality in D is still poor — tracked under the denoise project, not a regression.
- **N127 — ML denoise shim is never injected in `vite dev`.** The `lotusDenoise` plugin injects only on `closeBundle` (build), so ML noise suppression is silently inactive during local dev. Add a dev-mode injection (`configureServer` / `transformIndexHtml`). Dev-only impact. _Note: this **dissolves entirely** once denoise moves in-source in the fork (A7 fix) — there is then no build-time injection to be missing in dev._
- **N97 — Access token stored in plaintext `localStorage`** (`state/sessions.ts`), vulnerable to XSS; device ID likewise. Architectural — needs a token-protection / session-storage redesign.
- **Session writes are non-atomic and not cross-tab synced** (`state/sessions.ts`) — risks inconsistent state / races across tabs.
- **Persisted PII without encryption:** user status message + expiry (`settings/account/Profile.tsx`), unsent composer drafts (`room/RoomInput.tsx`). Leak risk on shared devices.
- **`matrix-js-sdk` pinned to a Release Candidate** (`41.6.0-rc.0`); `@atlaskit` and build tools (`vite`, `typescript`, `eslint`) on unstable/experimental pins — review for stable versions; RC SDK is a tree-shaking/bundle-size risk.
- **Build-time overhead:** `lotusDenoise` does heavy sequential `fs` work in `closeBundle`; `viteStaticCopy` config is complex with redundant renames — could be streamlined.
- **Automated test suite — seeded, expand coverage.** Harness now in place: `npm test` runs Node's built-in runner via `tsx` (not vitest — Vite 8 is ahead of vitest's range). 19 tests across `utils/common` + `utils/regex`. CI step is informational (`continue-on-error`) — promote to a hard gate when coverage is broader. **Next:** add suites for other pure-logic modules (search filters, ringtone gain math, mxc/url helpers), then component/integration tests.
- **`types/matrix/` mirrors SDK types** instead of importing them — drift risk.
- **Hardcoded CDN URL** should move to an env var (the decoration CDN is now single-sourced in `avatarDecorations.ts`, but the literal is still in-repo).
- **Architecture notes (low priority):** deep `features/` + `hooks/` nesting, many small coupled hooks, possible dead CSS/components, `SpacingVariant` / `DropTarget` recipe simplification.
- **Git workflow (forward-looking):** keep commits scoped — past monolithic "fix all bugs" commits and inconsistent prefixes hurt `git bisect`.
- **#5 — Seasonal themes & chat-background redesign.** Current backgrounds are basic CSS; goal is high-fidelity, research-backed, GPU-accelerated designs (layered `oklch`, `backdrop-filter`, `contain:paint`) with WCAG-AA overlay contrast. Treat each as its own design sprint.
