- `LogQueryController` — GET /api/v1/logs (filters: source, application, agentId, exchangeId, level, logger, q, environment, time range)
- `LogIngestionController` — POST /api/v1/data/logs (accepts `List<LogEntry>` JSON array, each entry has `source`: app/agent). Logs WARN for: missing agent identity, unregistered agents, empty payloads, buffer-full drops, deserialization failures. Normal acceptance at DEBUG.
- `CatalogController` — GET /api/v1/catalog (unified app catalog merging PG managed apps + in-memory agents + CH stats), DELETE /api/v1/catalog/{applicationId} (ADMIN: dismiss app, purge all CH data + PG record). Auto-filters discovered apps older than `discoveryttldays` with no live agents.

- `AgentEventsController` — GET /api/v1/agent-events (agent state change history)
- `AgentMetricsController` — GET /api/v1/agent-metrics (JVM/Camel metrics per agent instance)
- `AppSettingsController` — GET/PUT /api/v1/apps/{appId}/settings
- `ApplicationConfigController` — GET/PUT /api/v1/apps/{appId}/config (traced processors, route recording, sensitive keys per app)
- `ClickHouseAdminController` — GET /api/v1/admin/clickhouse (ClickHouse admin, conditional on infrastructure endpoints)

- `DetailController` — GET /api/v1/detail (execution detail with processor tree)
- `EventIngestionController` — POST /api/v1/data/events (agent event ingestion)
- `RbacStatsController` — GET /api/v1/admin/rbac/stats
- `RouteCatalogController` — GET /api/v1/routes/catalog (merged route catalog from registry + ClickHouse)
- `RouteMetricsController` — GET /api/v1/route-metrics (per-route Camel metrics)
- `ThresholdAdminController` — CRUD /api/v1/admin/thresholds
- `UsageAnalyticsController` — GET /api/v1/admin/usage (ClickHouse usage_events)

## runtime/ — Docker orchestration

- `DockerRuntimeOrchestrator` — implements RuntimeOrchestrator; Docker Java client (zerodep transport), container lifecycle
- `DeploymentExecutor` — @Async staged deploy: PRE_FLIGHT -> PULL_IMAGE -> CREATE_NETWORK -> START_REPLICAS -> HEALTH_CHECK -> SWAP_TRAFFIC -> COMPLETE. Container names are `{tenantId}-{envSlug}-{appSlug}-{replicaIndex}` (globally unique on Docker daemon). Sets per-replica `CAMELEER_AGENT_INSTANCEID` env var to `{envSlug}-{appSlug}-{replicaIndex}`.
- `DockerNetworkManager` — ensures bridge networks (cameleer-traefik, cameleer-env-{slug}), connects containers
- `DockerEventMonitor` — persistent Docker event stream listener (die, oom, start, stop), updates deployment status
- `TraefikLabelBuilder` — generates Traefik Docker labels for path-based or subdomain routing. Also emits `cameleer.replica` and `cameleer.instance-id` labels per container for labels-first identity.
- `PrometheusLabelBuilder` — generates Prometheus Docker labels (`prometheus.scrape/path/port`) per runtime type for `docker_sd_configs` auto-discovery
- `ContainerLogForwarder` — streams Docker container stdout/stderr to ClickHouse with `source='container'`. One follow-stream thread per container, batches lines every 2s/50 lines via `ClickHouseLogStore.insertBufferedBatch()`. 60-second max capture timeout.
- `DisabledRuntimeOrchestrator` — no-op when runtime not enabled

## metrics/ — Prometheus observability

- `ServerMetrics` — centralized business metrics: gauges (agents by state, SSE connections, buffer depths), counters (ingestion drops, agent transitions, deployment outcomes, auth failures), timers (flush duration, deployment duration). Exposed via `/api/v1/prometheus`.

## storage/ — PostgreSQL repositories (JdbcTemplate)

- `PostgresAppRepository`, `PostgresAppVersionRepository`, `PostgresEnvironmentRepository`
- `PostgresDeploymentRepository` — includes JSONB replica_states, deploy_stage, findByContainerId
- `PostgresUserRepository`, `PostgresRoleRepository`, `PostgresGroupRepository`
- `PostgresAuditRepository`, `PostgresOidcConfigRepository`, `PostgresClaimMappingRepository`, `PostgresSensitiveKeysRepository`
- `PostgresAppSettingsRepository`, `PostgresApplicationConfigRepository`, `PostgresThresholdRepository`

## storage/ — ClickHouse stores

- `ClickHouseExecutionStore`, `ClickHouseMetricsStore`, `ClickHouseMetricsQueryStore`
- `ClickHouseStatsStore` — pre-aggregated stats, punchcard
- `ClickHouseDiagramStore`, `ClickHouseAgentEventRepository`
- `ClickHouseUsageTracker` — usage_events for billing

## search/ — ClickHouse search and log stores

- `ClickHouseLogStore` — log storage and query, MDC-based exchange/processor correlation
- `ClickHouseSearchIndex` — full-text search

## security/ — Spring Security

- `SecurityConfig` — WebSecurityFilterChain, JWT filter, CORS, OIDC conditional
- `JwtAuthenticationFilter` — OncePerRequestFilter, validates Bearer tokens
- `JwtServiceImpl` — HMAC-SHA256 JWT (Nimbus JOSE)
- `OidcAuthController` — /api/v1/auth/oidc (login-uri, token-exchange, logout)
- `OidcTokenExchanger` — code -> tokens, role extraction from access_token then id_token
- `OidcProviderHelper` — OIDC discovery, JWK source cache

## agent/ — Agent lifecycle

- `SseConnectionManager` — manages per-agent SSE connections, delivers commands
- `AgentLifecycleMonitor` — @Scheduled 10s, LIVE->STALE->DEAD transitions
- `SsePayloadSigner` — Ed25519 signs SSE payloads for agent verification

## retention/ — JAR cleanup

- `JarRetentionJob` — @Scheduled 03:00 daily, per-environment retention, skips deployed versions

## config/ — Spring beans

- `RuntimeOrchestratorAutoConfig` — conditional Docker/Disabled orchestrator + NetworkManager + EventMonitor
- `RuntimeBeanConfig` — DeploymentExecutor, AppService, EnvironmentService
- `SecurityBeanConfig` — JwtService, Ed25519, BootstrapTokenValidator
- `StorageBeanConfig` — all repositories
- `ClickHouseConfig` — ClickHouse JdbcTemplate, schema initializer
