 All notable changes to Switchboard Core are documented here.

+## v0.5.3 — Chat Polish + Integration Testing
+
+### Added
+
+- **`db.query()` search_like**: New kernel-level `search_like` kwarg for text
+  search. Accepts `{col: pattern}` dict, generates OR-joined `LIKE` (SQLite) /
+  `ILIKE` (Postgres) clauses. Composes with existing `filters` via AND. Reusable
+  by any package. 5 new sandbox tests.
+- **Conversation search**: `GET /search?q=term` endpoint in `chat-core`. Searches
+  conversation titles and message content, scoped to user's conversations.
+  Returns `{conversations: [...], messages: [...]}`.
+- **Search UI**: Debounced search input in chat sidebar. Results view replaces
+  conversation list showing matched conversations and message snippets with
+  section headers. Click result to navigate, clear button to dismiss.
+- **`workflow-chat` library package**: `on_advance` hook that creates scoped
+  group conversations when workflow stages require team collaboration. Adds all
+  team members as participants, sends system message linking to the instance,
+  enriches `stage_data` with `conversation_id`. Idempotent — skips if
+  conversation already exists.
+- **Multi-user E2E test infrastructure**: `docker-compose-e2e.yml` with 2
+  replicas, Postgres, and nginx load balancer. `ci/e2e-chat-test.sh` shell
+  script covering auth, conversation CRUD, message send/read, cross-replica
+  consistency, search, and pagination. `ci/e2e-ws-listener.js` Node.js
+  WebSocket client for realtime event testing.
+- **Workflow hook tests**: 6 new Go tests for `parseOnAdvanceResult` covering
+  None, nil, error, enriched stage_data, non-dict, and nested structure cases.
+
+### Changed
+
+- **Message pagination polish**: Scroll position now preserved when loading older
+  messages — records `scrollHeight` before prepend, restores via
+  `requestAnimationFrame`. Loading spinner shown at top of thread during fetch.
+  "Load older messages" button hidden while loading.
+- **chat-core** bumped to v0.2.0 (new search endpoint).
+- **chat** bumped to v0.2.0 (search UI, pagination polish).

 | Step | Status | Description |
 |------|--------|-------------|
-| Conversation search | | Search across conversation titles and message content. |
-| Message pagination | | Cursor-based pagination on message history. Scroll-to-load-more in thread view. |
-| Multi-user E2E | | Docker compose test: multiple browser sessions, verify real-time message delivery, presence indicators, cross-replica broadcast. |
-| Workflow integration | | Verify: workflow stage with `audience: team` can create a conversation via `chat.create()`, add assigned members as participants. Conversation scoped to instance. |

+# Workflow Chat Integration
+
+Creates scoped chat conversations when workflow stages require team collaboration.
+
+## Setup
+
+1. Install the `workflow-chat` and `chat-core` packages.
+2. In your workflow stage with `audience: team`, set `stage_config`:
+
+```json
+{
+  "on_advance": {
+    "package_id": "workflow-chat",
+    "entry_point": "on_advance"
+  }
+}
+```
+
+3. When the workflow advances to that stage, ensure `stage_data` includes:
+
+```json
+{
+  "title": "Bug Triage Discussion",
+  "team_members": [
+    {"id": "user-1", "display_name": "Alice"},
+    {"id": "user-2", "display_name": "Bob"}
+  ],
+  "creator_id": "user-1",
+  "creator_display_name": "Alice"
+}
+```
+
+The hook will:
+- Create a group conversation titled `"Bug Triage Discussion [abcd1234]"` (suffixed with instance ID)
+- Add all team members as participants
+- Send a system message linking to the workflow instance
+- Enrich `stage_data` with the `conversation_id`
+
+## Idempotency
+
+If `stage_data` already contains a `conversation_id`, the hook returns `None` (no-op).
