+## [v0.30.1] CLI Session Bridge Fixes
+*April 4, 2026 | 424 tests*
+
+### Bug Fixes
+- **CLI sessions not appearing in sidebar.** Three frontend gaps: `sessions.js`
+  wasn't rendering CLI sessions (missing `is_cli_session` check in render loop),
+  sidebar click handler didn't trigger import, and the "cli" badge CSS selector
+  wasn't matching the rendered DOM structure. (#58)
+- **CLI bridge read wrong profile's state.db.** `get_cli_sessions()` resolved
+  `HERMES_HOME` at server launch time, not at call time. After a profile switch,
+  it kept reading the original profile's database. Now resolves dynamically via
+  `get_active_hermes_home()`. (#59)
+- **Silent SQL error swallowed all CLI sessions.** The `sessions` table in
+  `state.db` has no `profile` column — the query referenced `s.profile` which
+  caused a silent `OperationalError`. The `except Exception: return []` handler
+  swallowed it, returning zero CLI sessions. Removed the column reference and
+  added explicit column-existence checks. (#60)
+
+### Features
+- **"Show CLI sessions" toggle in Settings.** New checkbox in the Settings panel
+  to show/hide CLI sessions in the sidebar. Persisted server-side in
+  `settings.json` (`show_cli_sessions`, default `true`). When disabled, CLI
+  sessions are excluded from `/api/sessions` responses. (#61)
