openalice-live

Standalone Agent Desktop OS — fullscreen virtual desktop the agent drives via the same scene-control WS as the OBS scene mode. Persists window layout in localStorage so the surface survives reloads. Foundational v0 of the "fake OS in the browser" track.

Server-side proxy that mints openalice-browse sessions for the OS BrowserApp. Keeps the internal secret on the server.

Liveness probe — returns 200 with timestamp for monitoring + Traefik healthchecks.

Server-side proxy that mints openalice-pty sessions for the OS TerminalApp. Keeps the internal secret on the server and hands the browser a fully-formed ws_url with a one-shot token query param.

Per-stream background-music engine. Hidden <audio> element loops the streamer's chosen BGM track (preset OR custom upload). Drives volume / loop / fade-in / fade-out / cross-fade-on-track-change / auto-ducking-when-TTS-speaks. Decoupled from voice + SFX surfaces; ducking listens to oa-voice-chunk + oa-voice-finished postMessages.

Wires the bgmRotation policy + persona-server SSE rotation events into the live scene BGM pipeline. Subscribes to idle.bgm_change, falls back to a client-side max-loops trigger, and applies a 2s crossfade via the underlying BgmPlayer.

Bundled background-music preset library — five royalty-free vibes (lofi-amber, synthwave-cyan, jazz-cafe, ambient-spacy, silence). Hub picker uses these as starting points; tenant-uploaded tracks plug into the same dropdown via the persona /v1/me/audio CRUD.

Live-page radio channel subscriber. Resolves a radio:<slug> bgm_source into a WebSocket subscription against openalice-radio; each now_playing frame updates the underlying BgmPlayer config so the live page picks up new tracks with the same cross-fade / duck-during-tts plumbing as static BGM.

Sound-effects audio engine for the live stream player. Listens to chat append / mood transition / gesture / subscribe / caption events and plays a short clip per channel, debounced per event type. Master / per-event volume + per-event URL overrides via `branding.theme.sfx`. Mounts only when `theme.sfx.enabled === true` so SFX-disabled streams pay zero cost.

Five bundled sound-effect preset vibes (silent / subtle-warm / arcade / sci-fi / nature) — each a coordinated set of audio clips for the stream player's chat, mood, gesture, subscribe, and caption events. Hub picker uses these as starting points; per-event URL overrides land on top via `branding.theme.sfx.sfx_<event>_url`.

Public form that asks tenants to email a password-reset link. Always returns generic copy to avoid account-enumeration leaks.

Public login form — email + password, two-leg MFA prompt for accounts with TOTP/email-MFA.

Heuristic password-strength meter (close-enough to zxcvbn) plus visual bars. Stays local until v0.7 promotes a shared meter.

Lands here from the password-reset email link. Form: new password + confirm. POSTs to /tenants/reset-password.

Stash tenants-issued JWT into the shared SSO localStorage slot.

Public signup form — email, username, display name, password (with strength meter), ToS opt-in.

Confirms the verification token from the welcome email. Auto-POSTs on mount; surfaces a re-send button on failure when the user is logged in.

Game-style up-front asset preloader — fetches every URL the active theme references (VRM via persona, HDR env, BGM, scene background video/image, parallax layers, custom fonts, SFX bundle) before the scene fades in. Branded progress UI with X/Y count and percentage. 30 s safety timeout, soft per-asset failures don't block the scene. Eliminates the late-load "model loads on first scene with avatar" hiccup.

Marketing landing for OpenAlice Live — stream with Alice as AI co-host.

Real xterm.js terminal in the Agent Desktop OS — connects to openalice-pty over WebSocket and renders any TUI (claude, vim, btop, htop, neovim, tmux) pixel-perfect with full ANSI escape support.

AFK placard with a tasteful sleeping-moon SVG animation, breathing BRB title, and desaturated gradient mesh that signals "paused". Atelier-only, prefers-reduced-motion respected.

Subscribe / follow / donation celebration-overlay layer for the live broadcast page. Listens for `oa-event-celebrate` window events and slides a branded animated card into the scene with platform-coloured chrome, a confetti burst, optional TTS read-out, and per-platform SFX. Queues up to 16 events; honours reduced-motion. Mount-time gated by `theme.event_celebration.enabled`. Closes the polish gap to Streamlabs / StreamElements / Neuro-sama-grade event handling.

Editorial chapter card for between-segments transitions ("1 / 3 — Coding session"). Twin-band gradient mesh, oversized chapter index, slow horizontal wipe transition. Calm, intentional, premium.

Catalog of Live broadcast scene modes — VRM fullscreen + static placards (starting-soon / be-right-back / outro). Each scene declares its voice + render cost so the page knows whether to attach the SFU and the admin can warn on GPU-less hosts.

Administrative toast for AI-driven mod actions on the live scene. Listens for `oa-mod-action` window events and paints a muted lower-left card with an inline Undo button. Separate from the celebratory overlays — visually neutral on purpose.

Polished farewell placard with social-handle pills, optional next-stream timestamp, Solar Amber Subscribe CTA, and Plasma Cyan gradient mesh distinct from the warm starting-soon family.

Shared placard primitives — Atelier-themed gradient mesh, brand watermark, social pills, BGM "now playing" pill, countdown clock. Used by starting-soon / be-right-back / outro / intermission.

Engagement poll overlay for the live scene page. Listens for oa-poll-opened / oa-poll-vote / oa-poll-closed window events and paints a Q+A card with growing option bars + linear countdown + winning-option highlight on close. Optional per-platform colour theme.

Channel-point / SuperChat redemption toast for the live scene page. Listens for `oa-redemption-triggered` window events and paints a per-platform branded card ("🎁 ViewerName redeemed «Evil Laugh»"). Separate from the EventCelebrationOverlay (which handles sub/follow/cheer); this one is the dedicated viewer-trigger surface.

Animated 2D backdrop renderer for vtuber scenes — color / image / video / preset modes plus parallax layers, atmospheric particles (snow / cherry-blossoms / embers / dust / rain / stars), and drift (slow-pan / Ken-Burns). Pure CSS keyframes, no canvas, no WebGL — runs at ~0% GPU on the no-GPU broadcaster host. Reduced-motion strips every animation.

Polished pre-roll placard with Atelier gradient mesh, animated countdown to start_at_ms, brand block, and "now playing" pill. Atelier-only colours, calm motion, prefers-reduced-motion respected.

Floating reviewer-navigation overlay on the live demo page (?demo=1&picker=1) — six tabs (Scene / Render / Avatar / Theme / Background / Audio) let a reviewer hop between any combination of scene modes, avatar render modes/presets, theme presets, background presets, BGM and SFX presets in two clicks each. Pauses the auto-cycling demo timeline so selections stick. URL state syncs via history.replaceState so refreshes keep the reviewer's working selection.

Canned timeline of scene/mood/chat/gesture/window/splitscreen events the demo room replays on a loop so we exercise every renderer mode without requiring live agents or a WS connection.

Route-segment ErrorBoundary for /scene/[user]. Any unhandled error in the OBS Browser Source page renders a "Reconnecting…" card on a dark background instead of a blank surface, then auto-reloads after 3s so transient failures (WS drop, iframe race, persona crash) recover without operator intervention.

OBS Browser Source endpoint — multi-mode renderer (VRM fullscreen + static placards) driven by ?scene= query param and a live-control WebSocket so the agent's ChangeScene ToolCall flips scenes mid-stream without restarting the broadcaster Chromium.

Agent Marketplace browse + pair UI — capability-scoped grants against openalice-tenants.

Per-channel volume mixer + BGM picker for the active broadcast. Sliders for mic / desktop / TTS / BGM (linear UI, log-mapped on send), default royalty-free BGM presets, custom URL field, play/pause/skip transport, persisted per-broadcast in localStorage, debounced 200 ms before POST to live-control.

Multi-platform live chat reader + reply box for the streamer. Subscribes to the live-control scene WS for inbound, posts to chat-bridge for outbound. Lets the streamer talk to viewers without leaving studio.

Streamer-facing studio — shows the OBS browser-source URL with copy-to-clipboard. Login required.

First-run checklist for Live — avatar, voice, stream destination, desktop pairing, branding. Each step deeplinks to the editor that fixes it.

Per-user TTS / STT / avatar / system-prompt editor for the Live product. Saves to agent_config; takes effect on the next /live/start.

Privacy & Data settings — consent flags, GDPR export, audit log, paired agents, account deletion.

Browser HTTP client for openalice-tenants — consent flags, audit log, GDPR export, account deletion, paired-agent grants.

Per-stream visual theme for the broadcast player. Decouples streamer-facing scene look from the Atelier platform tokens — themes are CSS variables (bg / fg / accent / fonts / texture / motion) scoped to the player's <main> element. Streamers pick from a preset library (vtuber-warm, vtuber-neon-cyan, minimal-mono, glass-dark, vintage-sepia, pastel-bubblegum, editorial-print) or pass a fully-custom override. Atelier values are the fallback so existing broadcasts paint identically.
