+### User Story 4 - Configurable Logging Levels (Priority: P1)
+
+As an admin, I want to configure logging levels through the frontend so that I can control verbosity and filter noise during debugging.
+
+**Why this priority**: Essential for production debugging and performance tuning.
+
+**Independent Test**: Change the log level from INFO to DEBUG in admin settings, run a task, and verify that DEBUG-level logs (including belief_scope) now appear.
+
+**Acceptance Scenarios**:
+
+1. **Given** I am an admin user, **When** I navigate to Admin Settings > Logging, **Then** I see options for log level, task log level, and belief_scope toggle.
+2. **Given** belief_scope logging is enabled, **When** I set log level to DEBUG, **Then** all belief_scope Entry/Exit/Coherence logs are visible.
+3. **Given** belief_scope logging is enabled, **When** I set log level to INFO, **Then** belief_scope logs are hidden (they are DEBUG level).
+4. **Given** I set task_log_level to WARNING, **When** a task runs, **Then** only WARNING and ERROR logs are persisted for that task.
+

 ### Edge Cases
 
 - **High Volume Logs**: How does the system handle a task generating 10,000+ logs in a few seconds? (Requirement: Batching and virtual scrolling).

 - **FR-009**: Task logs MUST follow the same retention policy as task records (logs are kept as long as the task record exists).
 - **FR-010**: The default log level filter in the UI MUST be set to INFO and above (hiding DEBUG logs by default).
 - **FR-011**: System MUST support filtering logs by specific keys within the `metadata` JSON (e.g., `dashboard_id`, `database_uuid`).
+- **FR-012**: System MUST separate log levels clearly: DEBUG (development/tracing), INFO (normal operations), WARNING (potential issues), ERROR (failures).
+- **FR-013**: `belief_scope` context manager MUST log at DEBUG level (not INFO) to reduce noise in production.
+- **FR-014**: Admin users MUST be able to configure logging levels through the frontend settings UI.
+- **FR-015**: System MUST support separate log level configuration for application logs vs task-specific logs.

+  - Explain belief_scope and when to use it
+  - Show TaskContext usage patterns
+  - Add examples for source attribution
+  - **COMPLETED (2026-02-07)**: Added log level usage table, common source names table, and best practices section.
