 - Allowed disabled Pushover notification settings to clear the stored user key through the public API contract.
 - Unified the desktop shell chrome like Slack: title bar, workspace rail, and sidebar share one continuous plate with the conversation floating on it as a rounded card, the sidebar workspace header and the in-card channel header are gone on desktop — the workspace name (click for workspace settings) and the current channel or DM title live in the title bar — and the always-on "Connected" labels are gone everywhere (app settings stay on the native menu and Cmd/Ctrl+,; a pulsing "Connecting…" note appears only while the realtime link is down). The browser app keeps its sidebar workspace header and channel header unchanged.
 - Fixed live agent-activity bursts so same-turn preambles grow in place without dropping realtime rows or pulling a bottom-pinned timeline away from the live edge.
+- Added typed agent-progress SDK payloads while preserving workspace-wide presence events without channel or DM targets. Thanks @arcabotai for surfacing the integration needs.
 - Softened message bubbles: hairline accent-tint borders replace the heavier outlines, gentler keycap under-edges, and roomier padding.
 - Added Appearance settings with a light/dark/system color mode and four full-app board themes (Signal, the heritage Ember, Moss, Iris) — each tuned for both modes via a light-dark() token refactor, applied instantly with live swatch previews, persisted per device, and flash-free on load.
 - Redesigned the product site around the "Switchboard" keycap identity: cool porcelain/night-board themes over a dot-grid plate, electric cyan accent with indigo bot/thread tones, keycap buttons and step markers with press states, Bricolage Grotesque display type, and mono kickers/labels.

 `POST /api/realtime/ephemeral` validates workspace membership and tags the
 payload with `user_id` from the caller before publishing.
 
+The TypeScript SDK exports `AgentProgressLine`, `AgentProgressPayload`, and
+`EphemeralEventInput`. Its input union requires one target for typing and agent
+progress while retaining targetless, workspace-wide presence events.

 ## Recovery rules
 
 - The client sends `after_cursor` on every connect/reconnect.

+Bot tokens can publish typed, target-scoped agent progress:
+

+await client.events.publishEphemeral({
+  workspaceId,
+  channelId,
+  type: "agent.progress",
+  payload: {
+    turn_id: sourceMessageId,

+  },
+});
+```
+
+`agent.progress` requires a bot token and exactly one channel or DM target.
+Typing events have the same target rule. Presence events may instead omit both
+targets to publish workspace-wide.
