Multiple RateLimitMiddleware instances were each calling
check_allowed() on every request, halving the effective global
limit (200 req/min became ~100). Added path_prefixes and skip_paths
so each instance only checks the paths it owns.

Stale sessions from a stolen device could be reused up to the cache
TTL after a legitimate user re-logs in, because login never cleared
the existing cache entry.
Changes:
- Add invalidate_by_user(user_id) to SessionCache protocol
- InMemorySessionCache maintains a user_id -> set[token] index to
support O(1) invalidation of all sessions for a given user
- NoOpSessionCache stub updated for API compatibility
- auth_service.login() now returns the Session object alongside
signed_token and expires_at
- login router calls session_cache.invalidate_by_user(session.id)
immediately after successful authentication

Fail with RuntimeError when WEB_CONCURRENCY or BANGUI_WORKERS > 1.
In-memory session cache, rate-limit windows, and runtime state are
process-local. Multi-worker silently causes stale limits, ghost sessions,
inconsistent status.
Skipped when TESTING=1.

Add explicit HTTP status code documentation to every endpoint
across 15 router files. Each endpoint now declares all possible
response codes (200/201/204/400/401/404/409/429/502/503) with
descriptions so frontend can distinguish error types.

This commit adds support for shipping logs to external centralized logging platforms, addressing the MEDIUM priority task for structured logging infrastructure.
## Key Changes:
### 1. New Documentation: Docs/Observability.md
- Comprehensive guide to logging architecture and configuration
- Covers all three supported platforms (Datadog, Papertrail, Elasticsearch)
- Includes best practices, security considerations, and troubleshooting
- Documents sensitive data handling and compliance requirements
### 2. Core Implementation: app/utils/external_logging.py
- ExternalLogHandler: Abstract base class for non-blocking log delivery
- DatadogLogHandler: HTTP API integration with JSON payloads
- PapertrailLogHandler: Syslog protocol over TCP
- ElasticsearchLogHandler: Bulk API integration with NDJSON format
- Features:
- Async buffering with configurable batch size and flush interval
- Exponential backoff retry logic
- Non-blocking delivery (never blocks application logic)
- Proper error handling and internal logging
- Lifecycle management (start/shutdown)
### 3. Configuration: app/config.py
- New Settings fields for external logging:
- external_logging_enabled (default: False)
- external_logging_provider (datadog/papertrail/elasticsearch)
- external_logging_buffer_size (default: 1000)
- external_logging_flush_interval_seconds (default: 5.0)
- Provider-specific configuration (API keys, hosts, batch sizes)
- All fields have sensible defaults
- Full field validation and normalization
### 4. Integration: app/main.py
- Global _external_log_handler for application lifecycle
- _external_logging_processor: structlog processor for handler integration
- Updated _configure_logging(): Add handler to processor chain when enabled
- Updated _lifespan(): Initialize handler before startup, shutdown on termination
### 5. Tests: backend/tests/test_external_logging.py
- 20 comprehensive tests covering all handlers and factory
- Configuration validation tests
- All tests passing
## Design Decisions:
1. **Non-blocking Delivery**: External logging never blocks request handling.
Failures are logged locally but don't impact application.
2. **Buffering Strategy**: In-memory buffer with configurable size prevents
unbounded memory growth. When buffer fills, oldest logs are dropped with
a warning.
3. **Retry Logic**: Transient failures (timeouts, 5xx errors) are retried
with exponential backoff. Permanent failures (bad credentials) are logged
and skipped.
4. **Disabled by Default**: External logging is opt-in via environment
variables, maintaining backward compatibility with existing deployments.
5. **Provider Flexibility**: Support for multiple platforms allows users to
choose based on their infrastructure (cloud-native, on-premise, etc).
## Backward Compatibility:
- All new configuration fields have defaults
- External logging disabled by default
- No changes to existing logging behavior unless explicitly configured
- No new required dependencies
## Testing:
- All 20 new tests passing
- Existing tests unaffected (same count of passing tests)
- Configuration validation tested
- Handler creation and lifecycle management tested

Adds support for gradual session secret rotation without forcing logout:
- Add BANGUI_SESSION_SECRET_PREVIOUS config field for rotation window
- Implement unwrap_session_token_with_rotation() to accept tokens signed with
either current or previous secret
- Update validate_session() to transparently accept old tokens during rotation
- Update logout() to accept tokens from both secrets
- Add comprehensive logging for rotation events and metrics
- Add 8 new tests covering all rotation scenarios
- Update documentation with step-by-step rotation strategy
- Update .env.example with previous secret field
Key features:
- No forced logout: old tokens continue working during rotation window
- Transparent validation: old tokens are automatically logged for monitoring
- Production-safe: can rotate secrets without service interruption
- Metrics-ready: logs track token rotation for observability
Rotation workflow:
1. Generate new secret and set BANGUI_SESSION_SECRET
2. Set BANGUI_SESSION_SECRET_PREVIOUS to old secret
3. Wait for old tokens to expire (≥ session_duration_minutes)
4. Unset BANGUI_SESSION_SECRET_PREVIOUS to complete rotation
