+# Phase 3: Agent Registry + SSE Push Verification Report
+
+**Phase Goal:** Agent lifecycle management (LIVE/STALE/DEAD), SSE push for config/commands
+**Verified:** 2026-03-11
+**Status:** PASSED
+**Re-verification:** No — initial verification
+

+
+## Goal Achievement
+
+### Observable Truths (Plan 01)
+
+| # | Truth | Status | Evidence |
+|---|-------|--------|----------|
+| 1 | Agent can register via POST /api/v1/agents/register and receive agentId + sseEndpoint + heartbeatIntervalMs | VERIFIED | `AgentRegistrationController.register()` returns all three fields; IT test `registerNewAgent_returns200WithAgentIdAndSseEndpoint` asserts them |
+| 2 | Re-registration with same agentId resumes LIVE state, updates metadata | VERIFIED | `AgentRegistryService.register()` uses `agents.compute()` with existing-check; IT test `reRegisterSameAgent_returns200WithLiveState` passes |
+| 3 | Agent can send heartbeat via POST /{id}/heartbeat — 200 for known, 404 for unknown | VERIFIED | `AgentRegistrationController.heartbeat()` returns 404 if `registryService.heartbeat()` returns false; both paths covered by IT tests |
+| 4 | Server transitions LIVE->STALE after 90s, STALE->DEAD 5min after staleTransitionTime | VERIFIED | `AgentRegistryService.checkLifecycle()` implements both transitions with threshold comparison; unit tests `liveAgentBeyondStaleThreshold_transitionsToStale` and `staleAgentBeyondDeadThreshold_transitionsToDead` pass with 1ms thresholds |
+| 5 | GET /api/v1/agents returns all agents, filterable by ?status= | VERIFIED | `AgentRegistrationController.listAgents()` calls `findByState()` or `findAll()`; IT tests cover filter, all-list, and invalid-status=400 |
+
+### Observable Truths (Plan 02)
+
+| # | Truth | Status | Evidence |
+|---|-------|--------|----------|
+| 6 | Registered agent can open SSE stream at GET /{id}/events and receive events | VERIFIED | `AgentSseController.events()` calls `connectionManager.connect()` returning `SseEmitter(Long.MAX_VALUE)`; IT test `sseConnect_registeredAgent_returnsEventStream` asserts 200 |
+| 7 | Server pushes config-update events to agent's SSE stream | VERIFIED | `AgentCommandController` -> `registryService.addCommand()` -> `SseConnectionManager.onCommandReady()` -> `sendEvent()` with event name `config-update`; IT test `configUpdateDelivery_receivedViaSseStream` asserts `event:config-update` and data in stream |
+| 8 | Server pushes deep-trace commands with correlationId in payload | VERIFIED | Same pipeline with `deep-trace` event type; IT test `deepTraceDelivery_receivedViaSseStream` asserts `event:deep-trace` and `test-123` in stream |
+| 9 | Server pushes replay commands | VERIFIED | Same pipeline with `replay` event type; IT test `replayDelivery_receivedViaSseStream` asserts `event:replay` and `ex-456` in stream |
+| 10 | Commands can target all agents in a group via POST /groups/{group}/commands | VERIFIED | `AgentCommandController.sendGroupCommand()` filters LIVE agents by group; IT test `sendGroupCommand_returns202WithTargetCount` asserts targetCount=2 for 2 agents in group |
+| 11 | Commands can be broadcast to all live agents via POST /commands | VERIFIED | `AgentCommandController.broadcastCommand()` uses `findByState(LIVE)`; IT test `broadcastCommand_returns202WithLiveAgentCount` asserts targetCount >= 1 |
+| 12 | SSE stream receives ping keepalive comment every 15s (1s in tests) | VERIFIED | `SseConnectionManager.pingAll()` sends `SseEmitter.event().comment("ping")`; scheduled at `${agent-registry.ping-interval-ms:15000}`; test config sets 1000ms; IT test `pingKeepalive_receivedViaSseStream` asserts `:ping` in stream |
+| 13 | SSE events include event ID for Last-Event-ID reconnection (no replay) | VERIFIED | `SseConnectionManager.sendEvent()` sets `.id(eventId)` where eventId is command UUID; `AgentSseController` accepts `Last-Event-ID` header and logs at debug (no replay per decision); IT test `lastEventIdHeader_connectionSucceeds` asserts 200 |
+| 14 | Agent can acknowledge command via POST /{id}/commands/{commandId}/ack | VERIFIED | `AgentCommandController.acknowledgeCommand()` calls `registryService.acknowledgeCommand()`; IT tests cover 200 on success and 404 on unknown command |
+
+**Score: 14/14 truths verified**

+## Requirements Coverage
+
+| Requirement | Source Plan | Description | Status | Evidence |
+|-------------|-------------|-------------|--------|---------|
+| AGNT-01 (#13) | 03-01 | Agent registers via POST /api/v1/agents/register, receives JWT + server public key | SATISFIED | Registration endpoint works; `serverPublicKey` placeholder returns `null` (JWT/key deferred to Phase 4 per plan, endpoint structure present) |
+| AGNT-02 (#14) | 03-01 | Server maintains agent registry with LIVE/STALE/DEAD lifecycle based on heartbeat timing | SATISFIED | `AgentRegistryService.checkLifecycle()` + `AgentLifecycleMonitor` implement full LIVE->STALE->DEAD with configurable thresholds |
+| AGNT-03 (#15) | 03-01 | Agent sends heartbeat via POST /api/v1/agents/{id}/heartbeat every 30s | SATISFIED | Endpoint implemented; server advertises `heartbeatIntervalMs: 30000` in registration response |
+| AGNT-04 (#16) | 03-02 | Server pushes config-update events to agents via SSE with Ed25519 signature | SATISFIED* | SSE push for config-update implemented; Ed25519 signature deferred to Phase 4 (SECU-04); command payload pushed as raw JSON |
+| AGNT-05 (#17) | 03-02 | Server pushes deep-trace commands to agents via SSE for specific correlationIds | SATISFIED | `deep-trace` event type implemented; correlationId included in payload JSON |
+| AGNT-06 (#18) | 03-02 | Server pushes replay commands to agents via SSE with signed replay tokens | SATISFIED* | `replay` event type implemented; signing deferred to Phase 4 (SECU-04) |
+| AGNT-07 (#19) | 03-02 | SSE connection includes ping keepalive and supports Last-Event-ID reconnection | SATISFIED | Ping comment every 15s (1s in tests); Last-Event-ID header accepted; event IDs set on all events |
+
+_* AGNT-04 and AGNT-06 require Ed25519 signing per the requirement text. The signing is explicitly deferred to Phase 4 (SECU-03/SECU-04). The SSE push infrastructure is complete and functional. The signing gap is tracked in Phase 4's scope, not a Phase 3 failure._
+
+**No orphaned requirements** — all 7 AGNT requirements mapped to this phase appear in plan frontmatter and are accounted for.

+
+## Anti-Patterns Found
+
+| File | Pattern | Severity | Impact |
+|------|---------|----------|--------|
+| `AgentRegistrationController.java` line 96 | `serverPublicKey: null` placeholder | INFO | Intentional Phase 4 placeholder; no functional impact on Phase 3 goals |
+
+No TODOs, FIXMEs, empty implementations, or stub returns found in any Phase 3 implementation files.

+| `a1909ba` | 03-02 | SSE + command integration tests | Yes — in git log |
+
+---
+
+## Human Verification Required
+
+None. All automated checks pass. The SSE delivery path (command via HTTP -> SSE event on stream) is verified by integration tests using async `java.net.http.HttpClient` with `CountDownLatch` + `Awaitility` assertions.
+
+---
+
+## Summary
+
+Phase 3 goal is fully achieved. The implementation delivers:
+
+1. **Agent lifecycle management** — `AgentRegistryService` (plain Java, core module) implements full LIVE/STALE/DEAD state machine with configurable thresholds. `AgentLifecycleMonitor` drives periodic checks via `@Scheduled`. 23 unit tests cover all lifecycle transitions.
+
+2. **REST endpoints** — Registration (POST /register), heartbeat (POST /{id}/heartbeat), and listing (GET /agents with ?status= filter) are fully implemented with OpenAPI documentation. 7 integration tests verify all paths including 400 for invalid filter.
+
+3. **SSE push** — `SseConnectionManager` manages per-agent `SseEmitter` instances, implements `AgentEventListener` interface for zero-coupling event delivery from core to app layer. Ping keepalive at 15s (configurable). SSE events path excluded from `ProtocolVersionInterceptor` for EventSource client compatibility.
+
+4. **Command targeting** — Single agent, group, and broadcast targeting all implemented. Command acknowledgement endpoint complete. Command queue with PENDING/DELIVERED/ACKNOWLEDGED/EXPIRED status tracking.
+
+5. **Tests** — 23 unit tests + 7 + 13 integration tests (7 SSE + 6 command controller) = 43 tests covering Phase 3 code. Full suite of 71 tests passes per Summary.
+
+The `serverPublicKey: null` placeholder and unsigned SSE payloads are intentional — Ed25519 signing is Phase 4 scope (SECU-03, SECU-04). The SSE transport infrastructure is complete and ready to carry signed payloads in Phase 4.
