* fix(sessions): surface gateway SSE failures and add polling fallback
- add a JSON probe mode for the gateway SSE endpoint
- detect watcher-unavailable 503s from the browser
- fall back to periodic session refresh with a toast
- add probe payload tests and endpoint coverage
Fixes#635
* fix(sessions): surface gateway SSE failures and add polling fallback (#826)
Absorbed from PR #826 by @cloudyun888 (fixes#635).
When the gateway watcher thread is not running, the browser now shows a
toast notification and falls back to 30-second periodic polling for session
sync. Previously the SSE failure was completely silent with no user feedback.
Changes from original PR:
- Deleted misplaced test_gateway_sse_probe_unit.py (was at repo root, not
discovered by `pytest tests/`); unit tests moved into tests/test_gateway_sync.py
- _gateway_sse_probe_payload now checks watcher._thread.is_alive() rather
than just watcher is not None — a watcher instance with a dead poll thread
now correctly reports unavailable and activates the polling fallback
- probeGatewaySSEStatus catch(e) now starts the polling fallback on network
error rather than silently swallowing the failure
- Added 5 unit tests covering all watcher-alive/dead/missing/disabled branches

* cleanup(gateway): public is_alive() + dedup probe/live watcher-alive check + changelog
Three small cleanups on top of @cloudyun888's PR #826 absorption:
1. Add GatewayWatcher.is_alive() public accessor so routes.py doesn't
reach into the private _thread attribute. The existing private-
attribute check stays as a defensive fallback for any older in-
memory instance or test double that doesn't implement the full API.
2. Dedupe the watcher_alive computation in _handle_gateway_sse_stream:
the live-SSE path now calls _gateway_sse_probe_payload(...) and reads
its watcher_running field instead of re-deriving the same logic
inline. Keeps probe and SSE in sync automatically.
3. CHANGELOG trailer was (#826, fixes#635, @cloudyun888) — this PR is
#828, so updated to (#828, absorbs PR #826 by @cloudyun888, fixes
#635) matching the repo convention for absorbed PRs (see #805).
Added two regression tests:
- test_gateway_watcher_is_alive_public_method — covers the three
lifecycle states (before start, while running, after stop).
- test_probe_payload_prefers_public_is_alive — asserts the probe
uses watcher.is_alive() rather than poking _thread when the
public method exists.
Full suite: 1735 passed, 0 new failures.

* feat: add real-time gateway session sync (Phase 1)
- Add gateway_watcher.py: background daemon polling state.db every 5s
for gateway session changes (telegram, discord, slack, etc.)
- Extend get_cli_sessions() to include all non-webui sources
- Add SSE endpoint /api/sessions/gateway/stream for real-time push
- Add dynamic source badges (telegram=blue, discord=purple, slack=dark purple)
- Rename 'Show CLI sessions' to 'Show agent sessions'
- Wire watcher lifecycle into server start/stop
- 10 tests covering metadata, filtering, SSE, and watcher lifecycle
- Activated via the same checkbox as CLI session import
Addresses GitHub issue #272
* fix: SSE event name mismatch, TLS attribute, remove PLAN.md
- Fix critical SSE bug: frontend listened for 'gateway_session_update'
but backend sends 'sessions_changed' -- events were silently dropped
- Fix frontend field check: data.changed -> data.sessions (matches
the actual payload structure from gateway_watcher)
- Fix TLS: ssl.TLSv1_2 -> ssl.TLSVersion.TLSv1_2 (the bare attribute
does not exist, would crash TLS setup and silently fall back to HTTP)
- Remove PLAN.md: implementation plan should not be committed to repo

* fix: test isolation and slow-consumer sentinel in gateway sync
tests/test_gateway_sync.py:
- Fix _get_test_state_dir() path mismatch: the function was computing
HERMES_HOME/webui-mvp-test but conftest.py sets HERMES_HOME=TEST_STATE_DIR,
so state.db was written to a double-nested path the server never read.
Now uses HERMES_WEBUI_STATE_DIR first (which conftest sets directly to
TEST_STATE_DIR), fixing the 7/10 test failures in full-suite ordering.
- Fix conn cleanup: removed conn.close() from inside try blocks so the
connection stays valid for _remove_test_sessions() in the finally block.
Previously the closed conn caused ProgrammingError in finally (swallowed
by bare except), leaving ghost sessions in state.db on test failure.
api/gateway_watcher.py:
- Fix slow-consumer queue eviction: when a subscriber queue fills (>10 events)
and is removed from _subscribers, now puts a None sentinel into it so the
SSE handler unblocks and closes the connection, letting EventSource
auto-reconnect. Without this the connection stayed open but received no
further events.
* fix: test isolation — set HERMES_WEBUI_TEST_STATE_DIR in conftest
The gateway sync tests write directly to state.db and must use the same
path the test server reads from. Previously they computed the path
independently, which broke when test_auth_sessions.py set a different
HERMES_WEBUI_STATE_DIR in the test-process environment at import time.
tests/conftest.py:
- Set HERMES_WEBUI_TEST_STATE_DIR=TEST_STATE_DIR in the test process's
os.environ (via setdefault) so gateway tests can read it reliably.
Using setdefault preserves any explicit override the caller may pass.
tests/test_gateway_sync.py:
- Simplify _get_test_state_dir(): check HERMES_WEBUI_TEST_STATE_DIR first
(now reliably set by conftest), fall back to HERMES_HOME/webui-mvp-test.
Remove the workaround that tried to snapshot HERMES_HOME at import time.
Result: 658/658 tests pass in full-suite ordering (was 651 pass / 7 fail).
