User-facing data and config endpoints live under `/api/v1/environments/{envSlug}/...`. Env is a path segment, never a query param. The `envSlug` is resolved to an `Environment` bean via the `@EnvPath` argument resolver (`web/EnvironmentPathResolver.java`) — 404 on unknown slug.
**Slugs are immutable after creation** for both environments and apps. Slug regex: `^[a-z0-9][a-z0-9-]{0,63}$`. Validated in `EnvironmentService.create` and `AppService.createApp`. Update endpoints (`PUT`) do not accept a slug field; Jackson drops it as an unknown property.
### Flat-endpoint allow-list
These paths intentionally stay flat (no `/environments/{envSlug}` prefix). Every new endpoint should be env-scoped unless it appears here and the reason is documented.
| Path prefix | Why flat |
|---|---|
| `/api/v1/data/**` | Agent ingestion. JWT `env` claim is authoritative; URL-embedded env would invite spoofing. |
| `/api/v1/diagrams/{contentHash}/render`, `POST /api/v1/diagrams/render` | Content-addressed or stateless. |
| `/api/v1/auth/**` | Pre-auth; no env context exists. |
| `/api/v1/health`, `/prometheus`, `/api-docs/**`, `/swagger-ui/**` | Server metadata. |
## Tenant isolation invariant
ClickHouse is shared across tenants. Every ClickHouse query must filter by `tenant_id` (from `CAMELEER_SERVER_TENANT_ID` env var, resolved via `TenantContext`/config) in addition to `environment`. New controllers added under `/environments/{envSlug}/...` must preserve this — the env filter from the path does not replace the tenant filter.
-`AppController` — `/api/v1/environments/{envSlug}/apps`. GET list / POST create / GET `{appSlug}` / DELETE `{appSlug}` / GET `{appSlug}/versions` / POST `{appSlug}/versions` (JAR upload) / PUT `{appSlug}/container-config`. App slug uniqueness is per-env (`(env, app_slug)` is the natural key). `CreateAppRequest` body has no env (path), validates slug regex.
-`DeploymentController` — `/api/v1/environments/{envSlug}/apps/{appSlug}/deployments`. GET list / POST create (body `{ appVersionId }`) / POST `{id}/stop` / POST `{id}/promote` (body `{ targetEnvironment: slug }` — target app slug must exist in target env) / GET `{id}/logs`.
-`ApplicationConfigController` — `/api/v1/environments/{envSlug}`. GET `/config` (list), GET/PUT `/apps/{appSlug}/config`, GET `/apps/{appSlug}/processor-routes`, POST `/apps/{appSlug}/config/test-expression`. PUT also pushes `CONFIG_UPDATE` to LIVE agents in this env.
-`AppSettingsController` — `/api/v1/environments/{envSlug}`. GET `/app-settings` (list), GET/PUT/DELETE `/apps/{appSlug}/settings`. ADMIN/OPERATOR only.
-`SearchController` — `/api/v1/environments/{envSlug}`. GET `/executions`, POST `/executions/search`, GET `/stats`, `/stats/timeseries`, `/stats/timeseries/by-app`, `/stats/timeseries/by-route`, `/stats/punchcard`, `/attributes/keys`, `/errors/top`.
-`AgentEventsController` — GET `/api/v1/environments/{envSlug}/agents/events` (lifecycle events; cursor-paginated, returns `{ data, nextCursor, hasMore }`; order `(timestamp DESC, insert_id DESC)`; cursor is base64url of `"{timestampIso}|{insert_id_uuid}"` — `insert_id` is a stable UUID column used as a same-millisecond tiebreak).
-`AgentMetricsController` — GET `/api/v1/environments/{envSlug}/agents/{agentId}/metrics` (JVM/Camel metrics). Rejects cross-env agents (404) as defence-in-depth.
-`DiagramRenderController` — GET `/api/v1/environments/{envSlug}/apps/{appSlug}/routes/{routeId}/diagram` (env-scoped lookup). Also GET `/api/v1/diagrams/{contentHash}/render` (flat — content hashes are globally unique).
### Env admin (env-slug-parameterized, not env-scoped data)
-`EnvironmentAdminController` — `/api/v1/admin/environments`. GET list / POST create / GET `{envSlug}` / PUT `{envSlug}` / DELETE `{envSlug}` / PUT `{envSlug}/default-container-config` / PUT `{envSlug}/jar-retention`. Slug immutable — PUT body has no slug field; any slug supplied is dropped by Jackson. Slug validated on POST.
-`AgentRegistrationController` — POST `/register` (requires `environmentId` in body; 400 if missing), POST `/{id}/refresh` (rejects tokens with no `env` claim), POST `/{id}/heartbeat` (env from body preferred, JWT fallback; 400 if neither), POST `/{id}/deregister`.
-`AgentSseController` — GET `/{id}/events` (SSE connection).
-`AgentCommandController` — POST `/{agentId}/commands`, POST `/groups/{group}/commands`, POST `/commands` (broadcast), POST `/{agentId}/commands/{commandId}/ack`, POST `/{agentId}/replay`.
-`AgentConfigController` — GET `/api/v1/agents/config`. Agent-authoritative config read: resolves (app, env) from JWT subject → registry (registry miss falls back to JWT env claim; no registry entry → 404 since application can't be derived).
### Ingestion (agent-only, JWT-authoritative)
-`LogIngestionController` — POST `/api/v1/data/logs` (accepts `List<LogEntry>`; WARNs on missing identity, unregistered agents, empty payloads, buffer-full drops).
-`EventIngestionController` — POST `/api/v1/data/events`.
-`ChunkIngestionController` — POST `/api/v1/ingestion/chunk/{executions|metrics|diagrams}`.
-`ExecutionController` — POST `/api/v1/data/executions` (legacy ingestion path when ClickHouse disabled).
-`MetricsController` — POST `/api/v1/data/metrics`.
-`DiagramController` — POST `/api/v1/data/diagrams` (resolves applicationId + environment from the agent registry keyed on JWT subject; stamps both on the stored `TaggedDiagram`).
### Cross-env discovery (flat)
-`CatalogController` — GET `/api/v1/catalog` (merges managed apps + in-memory agents + CH stats; optional `?environment=` filter). DELETE `/api/v1/catalog/{applicationId}` (ADMIN: dismiss app, purge all CH data + PG record).
### Admin (cross-env, flat)
-`UserAdminController` — CRUD `/api/v1/admin/users`, POST `/{id}/roles`, POST `/{id}/set-password`.
-`OutboundConnectionAdminController` — `/api/v1/admin/outbound-connections`. GET list / POST create / GET `{id}` / PUT `{id}` / DELETE `{id}` / POST `{id}/test` / GET `{id}/usage`. RBAC: list/get/usage ADMIN|OPERATOR; mutations + test ADMIN.
-`SensitiveKeysAdminController` — GET/PUT `/api/v1/admin/sensitive-keys`. GET returns 200 or 204 if not configured. PUT accepts `{ keys: [...] }` with optional `?pushToAgents=true`. Fan-out iterates every distinct `(application, environment)` slice — intentional global baseline + per-env overrides.
-`ClaimMappingAdminController` — CRUD `/api/v1/admin/claim-mappings`, POST `/test`.
-`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`.
-`PostgresAppSettingsRepository`, `PostgresApplicationConfigRepository`, `PostgresThresholdRepository`. Both `app_settings` and `application_config` are env-scoped (PK `(app_id, environment)` / `(application, environment)`); finders take `(app, env)` — no env-agnostic variants.
-`crypto/SecretCipher` — AES-GCM symmetric cipher with key derived via HMAC-SHA256(jwtSecret, "cameleer-outbound-secret-v1"). Ciphertext format: base64(IV(12 bytes) || GCM output with 128-bit tag). `encrypt` throws `IllegalStateException`; `decrypt` throws `IllegalArgumentException` on tamper/wrong-key/malformed.
-`storage/PostgresOutboundConnectionRepository` — JdbcTemplate impl. `save()` upserts by id; JSONB serialization via ObjectMapper; UUID arrays via `ConnectionCallback`. Reads `created_by`/`updated_by` as String (= users.user_id TEXT).
-`OutboundConnectionServiceImpl` — service layer. Tenant bound at construction via `cameleer.server.tenant.id` property. Uniqueness check via `findByName`. Narrowing-envs guard: rejects update that removes envs while rules reference the connection (rulesReferencing stubbed in Plan 01, wired in Plan 02). Delete guard: rejects if referenced by rules.
-`controller/OutboundConnectionAdminController` — REST controller. Class-level `@PreAuthorize("hasRole('ADMIN')")` defaults; GETs relaxed to ADMIN|OPERATOR. Extracts acting user id from `SecurityContextHolder.authentication.name`, strips "user:" prefix. Audit via `AuditCategory.OUTBOUND_CONNECTION_CHANGE`.
-`dto/OutboundConnectionRequest` — Bean Validation: `@NotBlank` name, `@Pattern("^https://.+")` url, `@NotNull` method/tlsTrustMode/auth. Compact ctor throws `IllegalArgumentException` if TRUST_PATHS with empty paths list.
-`dto/OutboundConnectionDto` — response DTO. `hmacSecretSet: boolean` instead of the ciphertext; `authKind: OutboundAuthKind` instead of the full auth config.
-`dto/OutboundConnectionTestResult` — result of POST `/{id}/test`: status, latencyMs, responseSnippet (first 512 chars), tlsProtocol/cipherSuite/peerCertSubject (protocol is "TLS" stub; enriched in Plan 02 follow-up), error (nullable).
