Allows alert rules to fire on agent-lifecycle events — REGISTERED, RE_REGISTERED, DEREGISTERED, WENT_STALE, WENT_DEAD, RECOVERED — rather than only on current state. Each matching `(agent, eventType, timestamp)` becomes its own ackable AlertInstance, so outages on distinct agents are independently routable. Core: - New `ConditionKind.AGENT_LIFECYCLE` + `AgentLifecycleCondition` record (scope, eventTypes, withinSeconds). Compact ctor rejects empty eventTypes and withinSeconds<1. - Strict allowlist enum `AgentLifecycleEventType` (six entries matching the server-emitted types in `AgentRegistrationController` and `AgentLifecycleMonitor`). Custom agent-emitted event types tracked in backlog issue #145. - `AgentEventRepository.findInWindow(env, appSlug, agentId, eventTypes, from, to, limit)` — new read path ordered `(timestamp ASC, insert_id ASC)` used by the evaluator. Implemented on `ClickHouseAgentEventRepository` with tenant + env filter mandatory. App: - `AgentLifecycleEvaluator` queries events in the last `withinSeconds` window and returns `EvalResult.Batch` with one `Firing` per row. Every Firing carries a canonical `_subjectFingerprint` of `"<agentId>:<eventType>:<tsMillis>"` in context plus `agent` / `event` subtrees for Mustache templating. - `NotificationContextBuilder` gains an `AGENT_LIFECYCLE` branch that exposes `{{agent.id}}`, `{{agent.app}}`, `{{event.type}}`, `{{event.timestamp}}`, `{{event.detail}}`. - Validation is delegated to the record compact ctor + enum at Jackson deserialization time — matches the existing policy of keeping controller validators focused on env-scoped / SQL-injection concerns. Schema: - V16 migration generalises the V15 per-exchange discriminator on `alert_instances_open_rule_uq` to prefer `_subjectFingerprint` with a fallback to the legacy `exchange.id` expression. Scalar kinds still resolve to `''` and keep one-open-per-rule. Duplicate-key path in `PostgresAlertInstanceRepository.save` is unchanged — the index is the deduper. UI: - New `AgentLifecycleForm.tsx` wizard form with multi-select chips for the six allowed event types + `withinSeconds` input. Wired into `ConditionStep`, `form-state` (validation + defaults: WENT_DEAD, 300 s), and `enums.ts` options. Tests in `enums.test.ts` pin the new option array. - `alert-variables.ts` registers `{{agent.app}}`, `{{event.type}}`, `{{event.timestamp}}`, `{{event.detail}}` leaves for the new kind, and extends `agent.id`'s availability list to include `AGENT_LIFECYCLE`. Tests (all passing): - 5 new JSON-roundtrip cases on `AlertConditionJsonTest` (positive + empty/zero/unknown-type rejection). - 5 new evaluator unit tests on `AgentLifecycleEvaluatorTest` (empty window, multi-agent fingerprint shape, scope forwarding, missing env). - `NotificationContextBuilderTest` switch now covers the new kind. - 119 alerting unit tests + 71 UI tests green. Docs: `.claude/rules/{core,app,ui}` and CLAUDE.md migration list updated.
Cameleer UI
React SPA built with @cameleer/design-system v0.1.28, TanStack Query, and Zustand.
Development
npm install
npm run dev
By default the dev server proxies /api/* to http://localhost:8081. To proxy to a remote server instead:
VITE_API_TARGET=http://192.168.50.86:30081 npm run dev
No CORS issues — Vite's proxy makes API calls server-side.
Build
npm run build
