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.

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.
