Review Change Stack

📝 Walkthrough

Walkthrough

The change adds configurable automatic recreation for expired, non-terminated sessions. Server requests, active-session recovery, CLI clients, SDK clients, configuration files, and the UI now support the new behavior.

Changes

Session recreation

Layer / File(s) Summary
Configuration and UI controls
.env.example, docs/SESSION_ARCHITECTURE.md, memanto/app/config.py, memanto/cli/config/manager.py, memanto/app/ui/routes/ui_router.py, memanto/app/ui/static/index.html, tests/conftest.py, tests/test_session_config_overlay.py
Adds auto_recreate_enabled with YAML, environment, CLI, and UI support. Environment variables override YAML values. Runtime UI updates apply immediately.
Session recreation service flow
memanto/app/services/session_service.py, tests/test_unit.py
Validates expired tokens against persisted sessions, creates replacement sessions, preserves active markers, and excludes terminated, active, foreign, or malformed sessions.
HTTP authentication recovery
memanto/app/routes/auth_deps.py, tests/test_api.py
Uses management headers and loopback access to authorize recreation. Returns replacement tokens through cookies or X-Session-Token.
CLI and SDK session recovery
memanto/cli/client/direct_client.py, memanto/cli/client/sdk_client.py, memanto/cli/commands/_shared.py
Recreates expired sessions and refreshes cached tokens while preserving invalid-token and failed-recreation errors.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 22505

This PR adds automatic session recreation, but cached clients can still fail instead of renewing, concurrent recreation can select the wrong active session, and interrupted persistence can leave authentication state inconsistent; merge should wait for these bounded risks to be fixed or explicitly accepted.

Handle expiry from the populated cache.

After activate_agent, _cached_session is populated. If the process stays idle until expiry, these branches clear the cache and raise SessionExpiredError before the new recreation handler runs. Call check_and_auto_recreate(self.session_token) here, and raise only when it returns None.

  • memanto/cli/client/direct_client.py#L361-L365: recreate the expired cached session before raising.
  • memanto/cli/client/sdk_client.py#L193-L197: recreate the expired cached session before raising.

Do not overwrite a newer active marker during recreation.

Line 656 calls create_session, which always writes the global active marker. If one thread reads expired agent A, another thread activates agent B, and recreation then completes for A, this call changes the marker back to A. Subsequent active-session resolution selects the wrong agent.

Create the replacement without changing the marker. Update the marker only when it still names token.agent_id while holding _active_marker_lock. Add a concurrent activation regression test.

Preserve environment precedence for runtime toggles.

If SESSION_AUTO_RECREATE_ENABLED=False is set, settings.SESSION_AUTO_RECREATE_ENABLED is initialized to False. This assignment can replace it with the UI value True. The running server can then recreate expired sessions despite the documented environment precedence in docs/SESSION_ARCHITECTURE.md Lines 452-454.

Resolve the effective value with environment precedence before setattr, or reject the UI override when the environment variable is set.
