+### Removed
+
+- **~500 lines of dead CSS**: Orphaned classes for gutted chat, channel,
+  project, notes, editor-chat, sidebar, and router-picker features from
+  `layout.css` and `surfaces.css`.
+- **Dead Go types**: `Grant` struct (persona-era), `CompositeModelKey` func,
+  comment-only stubs for NoteGraph, ProjectChannel, etc.
+- **Dead event code**: `chat.typing.*` / `channel.typing.*` condition in WS
+  subscriber, empty Chat/Channel event route table sections.
+- **Dead test helpers**: `seed_helpers.go` (SeedTestMessage, SeedTestMessages,
+  SeedTestCursor — all callerless).
+- **Stale template refs**: CSS link tags for non-existent `sw-chat-pane.css`,
+  `sw-notes-pane.css`, `chat.css`. Orphaned `chat-pane.html` component.
+- **Vestigial guards**: `"chat"` surface checks in `IsSurfaceEnabled()` and
+  `DisablePackage()` (chat is no longer a surface).
+- Unused `fmt.Sprintf` references in team stores.
+
+### Changed
+
+- **Settings heading**: "Chat Defaults" renamed to "Defaults" in user settings.
+- Guard `sw.api.models.enabled()` call to prevent crash when no providers
+  are configured.
+- Updated bus doc examples and test labels from `chat.*` to `workflow.*`.
+- Renamed `channel-` prefixed test paths to `test-` in storage tests.
+- Updated doc comments throughout to remove references to gutted surfaces.
+
+### Added
+
+- **Package manifest icons**: Added emoji icons to hello-dashboard, icd-test-runner,
+  sdk-test-runner, and team-activity-log manifests.
+- **PoC documentation**: README.md for tasks and schedules packages documenting
+  Proof of Concept status and graduation criteria.
