Lotus Chat — Open Bugs & Technical Debt

Only OPEN and awaiting-verification items live here. Resolved findings (fixed-and-verified, false-positives, won't-fix) have been removed to keep this actionable — the full history is in git. Items fixed in code but not yet verified in a real environment are in Needs Verification below and have step-by-step checks in LOTUS_TESTING.md.

Design rules for any fix here: follow the Native-Cinny Law and TDS Design Law in LOTUS_TODO.md.

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.

🧩 Known Element Call iframe limitations (not fixable from our side)

🔱 [EC-FORK] These are the motivating issues for the Element Call fork initiative — see HANDOFF_ELEMENT_CALL_FORK.md. Once we build EC from our own source, A5/A6/A7 below become normal code fixes. (Correction: the iframe is actually same-origin / self-hosted — we just don't own EC's compiled source today.)

The in-call participant grid is rendered inside EC's iframe (a pre-built npm bundle we don't own), which we can style/place around but cannot change the logic of. Consequences from testing:

• A5 — "Focus camera": EC already supports native tile-pinning (click a video tile). Our bottom-bar "Focus camera" is a programmatic wrapper that clicks that tile; it can't live inside EC's UI. During a screenshare EC spotlights the shared screen and a camera pin may not override it. Decision: keep the shortcut, revisit with the larger call-UI/EC work.
• A6 — avatar decorations in-call: decorations render on our pre-join lobby roster (CallMemberCard) but cannot be drawn on EC's in-call video tiles. Working as designed given the iframe boundary.
• A7 — mic dead after EC's "Reconnect": the mid-call "Connection lost / Reconnect" screen is EC's own (our load watchdog only covers an initial hung load). After EC reconnects, the mic isn't re-published through our denoise getUserMedia shim until a clean End+rejoin. Tied to the denoise rework.

🔴 Open — Actionable

Calls / Audio

• 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.

Security & Privacy

• 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.

PWA / Offline / Notifications

• N105 — Service worker has no notificationclick handler — notification clicks are broken when the tab is closed. Needs showNotification() via the SW + a notificationclick listener.
• N107 — SW has no push handler — Web Push delivery is entirely non-functional. Needs a push listener + a Matrix push-gateway integration.
• No app-asset caching strategy (src/sw.ts) — no offline capability.
• manifest: false in vite.config.js — may block correct PWA install if not handled externally.

Dependencies & Build

• 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.

Code Hygiene / DevEx

• No automated test suite (src/) — no unit/integration tests configured.
• Extensive as any casts across src/ — gradual typing cleanup.
• 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).
• patch-folds.mjs edits node_modules directly — consider patch-package.
• Infra docs: contrib/nginx lacks security headers (HSTS/CSP) + uses rewrites over try_files; contrib/caddy has a placeholder path. CI/CD (prod-deploy.yml): sequential deploy, aggressive 1-min Netlify timeout, package-manager-cache: false.
• README: keep the fork-sync version + logo path current. (CONTRIBUTING.md is intentionally left as upstream Cinny's — not a Lotus concern.)
• 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.

Big Projects

• #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.
