# Core Module Key Classes

`cameleer-server-core/src/main/java/com/cameleer/server/core/`

## agent/ — Agent lifecycle and commands

- `AgentRegistryService` — in-memory registry (ConcurrentHashMap), register/heartbeat/lifecycle
- `AgentInfo` — record: id, name, application, environmentId, version, routeIds, capabilities, state
- `AgentCommand` — record: id, type, targetAgent, payload, createdAt, expiresAt
- `AgentEventService` — records agent state changes, heartbeats
- `AgentState` — enum: LIVE, STALE, DEAD, SHUTDOWN
- `CommandType` — enum for command types (config-update, deep-trace, replay, route-control, etc.)
- `CommandStatus` — enum for command acknowledgement states
- `CommandReply` — record: command execution result from agent
- `AgentEventRecord`, `AgentEventRepository` — event persistence. `AgentEventRepository.queryPage(...)` is cursor-paginated (`AgentEventPage{data, nextCursor, hasMore}`); the legacy non-paginated `query(...)` path is gone. `AgentEventRepository.findInWindow(env, appSlug, agentId, eventTypes, from, to, limit)` returns matching events ordered by `(timestamp ASC, insert_id ASC)` — consumed by `AgentLifecycleEvaluator`.
- `AgentEventPage` — record: `(List<AgentEventRecord> data, String nextCursor, boolean hasMore)` returned by `AgentEventRepository.queryPage`
- `AgentEventListener` — callback interface for agent events
- `RouteStateRegistry` — tracks per-agent route states

## runtime/ — App/Environment/Deployment domain

- `App` — record: id, environmentId, slug, displayName, containerConfig (JSONB)
- `AppVersion` — record: id, appId, version, jarPath, detectedRuntimeType, detectedMainClass
- `Environment` — record: id, slug, displayName, production, enabled, defaultContainerConfig, jarRetentionCount, color, createdAt. `color` is one of the 8 preset palette values validated by `EnvironmentColor.VALUES` and CHECK-constrained in PostgreSQL (V2 migration).
- `EnvironmentColor` — constants: `DEFAULT = "slate"`, `VALUES = {slate,red,amber,green,teal,blue,purple,pink}`, `isValid(String)`.
- `Deployment` — record: id, appId, appVersionId, environmentId, status, targetState, deploymentStrategy, replicaStates (JSONB), deployStage, containerId, containerName, createdBy (String, user_id reference; nullable for pre-V4 historical rows)
- `DeploymentStatus` — enum: STOPPED, STARTING, RUNNING, DEGRADED, STOPPING, FAILED. `DEGRADED` is reserved for post-deploy drift (a replica died after RUNNING); `DeploymentExecutor` now marks partial-healthy deploys FAILED, not DEGRADED.
- `DeployStage` — enum: PRE_FLIGHT, PULL_IMAGE, CREATE_NETWORK, START_REPLICAS, HEALTH_CHECK, SWAP_TRAFFIC, COMPLETE
- `DeploymentStrategy` — enum: BLUE_GREEN, ROLLING. Stored on `ResolvedContainerConfig.deploymentStrategy` as kebab-case string (`"blue-green"` / `"rolling"`). `fromWire(String)` is the only conversion entry point; unknown/null inputs fall back to BLUE_GREEN so the executor dispatch site never null-checks or throws.
- `DeploymentService` — createDeployment (calls `deleteFailedByAppAndEnvironment` first so FAILED rows don't pile up; STOPPED rows are preserved as restorable checkpoints), markRunning, markFailed, markStopped
- `RuntimeType` — enum: AUTO, SPRING_BOOT, QUARKUS, PLAIN_JAVA, NATIVE
- `RuntimeDetector` — probes JAR files at upload time: detects runtime from manifest Main-Class (Spring Boot loader, Quarkus entry point, plain Java) or native binary (non-ZIP magic bytes)
- `ContainerRequest` — record: 20 fields for Docker container creation (includes runtimeType, customArgs, mainClass)
- `ContainerStatus` — record: state, running, exitCode, error
- `ResolvedContainerConfig` — record: typed config with memoryLimitMb, memoryReserveMb, cpuRequest, cpuLimit, appPort, exposedPorts, customEnvVars, stripPathPrefix, sslOffloading, routingMode, routingDomain, serverUrl, replicas, deploymentStrategy, routeControlEnabled, replayEnabled, runtimeType, customArgs, extraNetworks, externalRouting (default `true`; when `false`, `TraefikLabelBuilder` strips all `traefik.*` labels so the container is not publicly routed), certResolver (server-wide, sourced from `CAMELEER_SERVER_RUNTIME_CERTRESOLVER`; when blank the `tls.certresolver` label is omitted — use for dev installs with a static TLS store)
- `RoutingMode` — enum for routing strategies
- `ConfigMerger` — pure function: resolve(globalDefaults, envConfig, appConfig) -> ResolvedContainerConfig
- `RuntimeOrchestrator` — interface: startContainer, stopContainer, getContainerStatus, getLogs, startLogCapture, stopLogCapture
- `AppRepository`, `AppVersionRepository`, `EnvironmentRepository`, `DeploymentRepository` — repository interfaces
- `AppService`, `EnvironmentService` — domain services

## search/ — Execution search and stats

- `SearchService` — search, count, stats, statsForApp, statsForRoute, timeseries, timeseriesForApp, timeseriesForRoute, timeseriesGroupedByApp, timeseriesGroupedByRoute, slaCompliance, slaCountsByApp, slaCountsByRoute, topErrors, activeErrorTypes, punchcard, distinctAttributeKeys. `statsForRoute`/`timeseriesForRoute` take `(routeId, applicationId)` — app filter is applied to `stats_1m_route`.
- `SearchRequest` / `SearchResult` — search DTOs. `SearchRequest.attributeFilters: List<AttributeFilter>` carries structured facet filters for execution attributes — key-only (exists), exact (key=value), or wildcard (`*` in value). The 21-arg legacy ctor is preserved for call-site churn; the compact ctor normalises null → `List.of()`.
- `AttributeFilter(key, value)` — record with key regex `^[a-zA-Z0-9._-]+$` (inlined into SQL, same constraint as alerting), `value == null` means key-exists, `value` containing `*` becomes a SQL LIKE pattern via `toLikePattern()`.
- `ExecutionStats`, `ExecutionSummary` — stats aggregation records
- `StatsTimeseries`, `TopError` — timeseries and error DTOs
- `LogSearchRequest` / `LogSearchResponse` — log search DTOs. `LogSearchRequest.sources` / `levels` are `List<String>` (null-normalized, multi-value OR); `cursor` + `limit` + `sort` drive keyset pagination. Response carries `nextCursor` + `hasMore` + per-level `levelCounts`.

## storage/ — Storage abstractions

- `ExecutionStore`, `MetricsStore`, `MetricsQueryStore`, `StatsStore`, `DiagramStore`, `RouteCatalogStore`, `SearchIndex`, `LogIndex` — interfaces. `DiagramStore.findLatestContentHashForAppRoute(appId, routeId, env)` resolves the latest diagram by (app, env, route) without consulting the agent registry, so routes whose publishing agents were removed between app versions still resolve. `findContentHashForRoute(route, instance)` is retained for the ingestion path that stamps a per-execution `diagramContentHash` at ingest time (point-in-time link from `ExecutionDetail`/`ExecutionSummary`).
- `RouteCatalogEntry` — record: applicationId, routeId, environment, firstSeen, lastSeen
- `LogEntryResult` — log query result record
- `model/` — `ExecutionDocument`, `MetricTimeSeries`, `MetricsSnapshot`

## rbac/ — Role-based access control

- `RbacService` — interface: role/group CRUD, assignRoleToUser, removeRoleFromUser, addUserToGroup, removeUserFromGroup, getDirectRolesForUser, getEffectiveRolesForUser, clearManagedAssignments, assignManagedRole, addUserToManagedGroup, getStats, listUsers
- `SystemRole` — enum: AGENT, VIEWER, OPERATOR, ADMIN; `normalizeScope()` maps scopes
- `UserDetail`, `RoleDetail`, `GroupDetail` — records
- `UserSummary`, `RoleSummary`, `GroupSummary` — lightweight list records
- `RbacStats` — aggregate stats record
- `AssignmentOrigin` — enum: DIRECT, CLAIM_MAPPING (tracks how roles were assigned)
- `ClaimMappingRule` — record: OIDC claim-to-role mapping rule
- `ClaimMappingService` — interface: CRUD for claim mapping rules
- `ClaimMappingRepository` — persistence interface
- `RoleRepository`, `GroupRepository` — persistence interfaces

## admin/ — Server-wide admin config

- `SensitiveKeysConfig` — record: keys (List<String>, immutable)
- `SensitiveKeysRepository` — interface: find(), save()
- `SensitiveKeysMerger` — pure function: merge(global, perApp) -> union with case-insensitive dedup, preserves first-seen casing. Returns null when both inputs null.
- `AppSettings`, `AppSettingsRepository` — per-app-per-env settings config and persistence. Record carries `(applicationId, environment, …)`; repository methods are `findByApplicationAndEnvironment`, `findByEnvironment`, `save`, `delete(appId, env)`. `AppSettings.defaults(appId, env)` produces a default instance scoped to an environment.
- `ThresholdConfig`, `ThresholdRepository` — alerting threshold config and persistence
- `AuditService` — audit logging facade
- `AuditRecord`, `AuditResult`, `AuditCategory` (enum: `INFRA, AUTH, USER_MGMT, CONFIG, RBAC, AGENT, OUTBOUND_CONNECTION_CHANGE, OUTBOUND_HTTP_TRUST_CHANGE, ALERT_RULE_CHANGE, ALERT_SILENCE_CHANGE, DEPLOYMENT`), `AuditRepository` — audit trail records and persistence

## http/ — Outbound HTTP primitives (cross-cutting)

- `OutboundHttpClientFactory` — interface: `clientFor(context)` returns memoized `CloseableHttpClient`
- `OutboundHttpProperties` — record: `trustAll, trustedCaPemPaths, defaultConnectTimeout, defaultReadTimeout, proxyUrl, proxyUsername, proxyPassword`
- `OutboundHttpRequestContext` — record of per-call TLS/timeout overrides; `systemDefault()` static factory
- `TrustMode` — enum: `SYSTEM_DEFAULT | TRUST_ALL | TRUST_PATHS`

## outbound/ — Admin-managed outbound connections

- `OutboundConnection` — record: id, tenantId, name, description, url, method, defaultHeaders, defaultBodyTmpl, tlsTrustMode, tlsCaPemPaths, hmacSecretCiphertext, auth, allowedEnvironmentIds, createdAt, createdBy (String user_id), updatedAt, updatedBy (String user_id). `isAllowedInEnvironment(envId)` returns true when allowed-envs list is empty OR contains the env.
- `OutboundAuth` — sealed interface + records: `None | Bearer(tokenCiphertext) | Basic(username, passwordCiphertext)`. Jackson `@JsonTypeInfo(use = DEDUCTION)` — wire shape has no discriminator, subtype inferred from fields.
- `OutboundAuthKind`, `OutboundMethod` — enums
- `OutboundConnectionRepository` — CRUD by (tenantId, id): save/findById/findByName/listByTenant/delete
- `OutboundConnectionService` — create/update/delete/get/list with uniqueness + narrow-envs + delete-if-referenced guards. `rulesReferencing(id)` stubbed in Plan 01 (returns `[]`); populated in Plan 02 against `AlertRuleRepository`.

## security/ — Auth

- `JwtService` — interface: createAccessToken, createRefreshToken, validateAccessToken, validateRefreshToken
- `Ed25519SigningService` — interface: sign, getPublicKeyBase64 (config signing)
- `OidcConfig` — record: enabled, issuerUri, clientId, clientSecret, rolesClaim, defaultRoles, autoSignup, displayNameClaim, userIdClaim, audience, additionalScopes
- `OidcConfigRepository` — persistence interface
- `PasswordPolicyValidator` — min 12 chars, 3-of-4 character classes, no username match
- `UserInfo`, `UserRepository` — user identity records and persistence
- `InvalidTokenException` — thrown on revoked/expired tokens

## ingestion/ — Buffered data pipeline

- `IngestionService` — diagram + metrics facade (`ingestDiagram`, `acceptMetrics`, `getMetricsBuffer`). Execution ingestion went through here via the legacy `RouteExecution` shape until `ChunkAccumulator` took over writes from the chunked pipeline — the `ingestExecution` path plus its `ExecutionStore.upsert` / `upsertProcessors` dependencies were removed.
- `ChunkAccumulator` — batches data for efficient flush; owns the execution write path (chunks → buffers → flush scheduler → `ClickHouseExecutionStore.insertExecutionBatch`).
- `WriteBuffer` — bounded ring buffer for async flush
- `BufferedLogEntry` — log entry wrapper with metadata
- `MergedExecution`, `TaggedDiagram` — tagged ingestion records. `TaggedDiagram` carries `(instanceId, applicationId, environment, graph)` — env is resolved from the agent registry in the controller and stamped on the ClickHouse `route_diagrams` row.
