BE-CAL-007: Workload warning computation (already implemented in prior wave,
verified tests pass - 24/24). Computes daily/weekly/monthly/yearly scheduled
minutes and compares against user thresholds. Warnings are advisory only.
BE-CAL-008: New slot_immutability service with guards for:
- Forbid edit/cancel of past real slots (raises ImmutableSlotError)
- Forbid edit/cancel of past virtual slots
- Plan-edit/plan-cancel helper to identify past materialized slot IDs
that must not be retroactively modified
Tests: 19/19 passing.
- New overlap.py service with check_overlap(), check_overlap_for_create(),
and check_overlap_for_edit() functions
- Detects same-day time conflicts for a user's calendar
- Checks both real (materialized) TimeSlots and virtual (plan-generated) slots
- Excludes skipped/aborted slots from conflict checks
- Edit scenario excludes the slot being edited from conflict candidates
- Returns structured SlotConflict objects with human-readable messages
- 24 passing tests covering no-conflict, conflict detection, inactive
exclusion, edit self-exclusion, virtual slot overlap, and message content
- New service: app/services/plan_slot.py
- Virtual slot ID: plan-{plan_id}-{YYYY-MM-DD} format with parse/make helpers
- Plan-date matching: on_month/on_week/on_day hierarchy with week_of_month calc
- Materialization: convert virtual slot to real TimeSlot row from plan template
- Detach: clear plan_id after edit/cancel to break plan association
- Bulk materialization: materialize_all_for_date for daily pre-compute
- New tests: tests/test_plan_slot.py (23 tests, all passing)
- accept nginx installation status and sites-enabled list
- persist nginx fields in server state
- expose nginx data in monitor overview/admin views
- auto-migrate new server_states columns on startup
- Add server_states.plugin_version column
- Keep openclaw_version for remote OpenClaw runtime version
- Expose plugin_version in monitor server view
- Accept and persist plugin_version in heartbeat payloads
Fixes datetime comparison error when last_seen_at from database is
offset-naive (no timezone info) while 'now' is offset-aware (UTC).
This resolves the TypeError: can't subtract offset-naive and
offset-aware datetimes issue in integration tests.
- New app/services/dependency_check.py with check_milestone_deps()
- Replaces 3x duplicated JSON-parse + query + filter logic
- Supports both milestone and task dependency checking
- Returns structured DepCheckResult with ok/blockers/reason
- Refactored preflight and start endpoints to use shared helper
