## Release v0.51.264 — Release IF (stage-r14)
Un-held sibling pair (#3585 + #3586) — both addressed the findings from the earlier hold; re-reviewed fresh.
### Fixed
| Issue/PR | Author | Fix |
|----------|--------|-----|
| #3585 | @rodboev | Cron sessions no longer flood the CLI sidebar window (restored the `("cron","webui")` exclusion in `_load_cli_sessions_uncached`). |
| #3586 | @rodboev | Messaging sessions keep their source label after a refresh **and open + send correctly** — `is_cli_session_row()` classifies them non-CLI, and the sidebar open/import path now uses `_isMessagingSession()` so a reclassified Discord/Telegram/Slack row is imported on open (no transient stub → no `/api/chat/start` 404). |
### Un-hold note
These were held earlier today because the `is_cli_session_row()` reclassification (#3586) created a CORE open-path regression — opening a reclassified messaging session 404'd on the next send. The author pushed a fix adding the `_isMessagingSession()` import gate at all open/lineage/refresh paths (+ regression test `test_issue3603_external_session_import_gate.py`), and Codex confirmed both that AND the secondary webui-recovery concern (cron-only exclusion now keeps `source='webui'` sidecar-less recovery rows) are resolved.
### Gate
- Full pytest suite: **7729 passed, 0 failed**
- ESLint: CLEAN · ruff: CLEAN · browser-smoke: CLEAN
- Codex (regression): **SAFE TO SHIP** — open→import→send path verified (messaging rows go through `/api/session/import_cli` before `/api/chat/start`); `is_cli_session_row` classification correct; the pair composes in `_load_cli_sessions_uncached`.
