Goal Achievement

Observable Truths

All truths drawn from PLAN frontmatter must_haves across plans 01, 02, and 03.

#	Truth	Status	Evidence
1	Ed25519 keypair generated at startup; public key available as Base64	VERIFIED	Ed25519SigningServiceImpl generates keypair via KeyPairGenerator.getInstance("Ed25519") in constructor; getPublicKeyBase64() returns Base64-encoded X.509 DER bytes
2	JwtService creates access tokens (1h) and refresh tokens (7d) with agentId, group, and type claims	VERIFIED	JwtServiceImpl.createToken() sets sub, group, type, iat, exp claims using Nimbus MACSigner/HS256; expiry from SecurityProperties
3	JwtService validates tokens and extracts agentId, distinguishing access vs refresh type	VERIFIED	validateToken() checks signature, expiration, and type claim; throws InvalidTokenException on any violation
4	BootstrapTokenValidator uses constant-time comparison and supports dual-token rotation	VERIFIED	Uses MessageDigest.isEqual() for both primary and previous token; null/blank guarded
5	Server fails fast on startup if CAMELEER_AUTH_TOKEN is not set	VERIFIED	SecurityBeanConfig registers an InitializingBean that throws IllegalStateException if bootstrapToken is null or blank
6	All API endpoints except health, register, and docs reject requests without valid JWT	VERIFIED	SecurityConfig permits /api/v1/health, /api/v1/agents/register, /api/v1/agents/*/refresh, Swagger docs, and /error; all other requests require authentication; SecurityFilterIT (6 tests) confirms
7	POST /register requires bootstrap token; returns JWT + refresh token + Ed25519 public key	VERIFIED	AgentRegistrationController.register() extracts and validates bootstrap token from Authorization: Bearer header, calls jwtService.createAccessToken/createRefreshToken and ed25519SigningService.getPublicKeyBase64(); RegistrationSecurityIT (3 tests) confirms
8	POST /agents/{id}/refresh accepts refresh token and returns new access JWT	VERIFIED	AgentRegistrationController.refresh() calls jwtService.validateRefreshToken(), verifies agent ID match, issues new access token; JwtRefreshIT (5 tests) confirms
9	All config-update, deep-trace, and replay SSE events carry a valid Ed25519 signature	VERIFIED	SseConnectionManager.onCommandReady() calls ssePayloadSigner.signPayload(command.payload()) before sendEvent(); SseSigningIT (2 tests) verify end-to-end signature against public key
10	Signature computed over original payload JSON, added as "signature" field	VERIFIED	SsePayloadSigner.signPayload() signs original string, parses JSON, adds "signature" field via ObjectNode.put(), re-serializes; SsePayloadSignerTest (7 tests) confirms including roundtrip verification

Score: 10/10 truths verified

Requirements Coverage

Requirement	Source Plan	Description	Status	Evidence
SECU-01 (#23)	Plan 02	All API endpoints (except health and register) require valid JWT Bearer token	SATISFIED	SecurityConfig enforces authentication on all non-public paths; SecurityFilterIT tests confirm 401/403 without JWT
SECU-02 (#24)	Plan 02	JWT refresh flow via POST /api/v1/agents/{id}/refresh	SATISFIED	AgentRegistrationController.refresh() endpoint; JwtRefreshIT (5 tests) cover valid/invalid/wrong-type/mismatch/chain cases
SECU-03 (#25)	Plan 01	Server generates Ed25519 keypair; public key delivered at registration	SATISFIED	Ed25519SigningServiceImpl generates keypair at construction; register() returns serverPublicKey from getPublicKeyBase64(); RegistrationSecurityIT confirms
SECU-04 (#26)	Plan 03	All config-update and replay SSE payloads are signed with server's Ed25519 private key	SATISFIED	SsePayloadSigner signs all command payloads; SseConnectionManager.onCommandReady() calls it; SseSigningIT verifies end-to-end signature
SECU-05 (#27)	Plans 01+02	Bootstrap token from CAMELEER_AUTH_TOKEN env var validates initial agent registration	SATISFIED	SecurityBeanConfig fails fast if missing; BootstrapTokenValidator checks with constant-time comparison; BootstrapTokenIT (4 tests) confirm

All 5 SECU requirements satisfied. No orphaned or unaccounted requirements.

Anti-Patterns Found

No anti-patterns detected in the security implementation files.

Scanned: JwtServiceImpl.java, Ed25519SigningServiceImpl.java, BootstrapTokenValidator.java, SecurityBeanConfig.java, JwtAuthenticationFilter.java, SecurityConfig.java, AgentRegistrationController.java, SsePayloadSigner.java, SseConnectionManager.java.

• No TODO/FIXME/placeholder comments
• No stub returns (empty arrays, null without reason, etc.)
• No console.log-only implementations
• No disabled wiring

One note: deferred-items.md documented 8 test failures at end of Plan 03. All are resolved — AgentSseControllerIT, AgentCommandControllerIT, and JwtRefreshIT all pass (verified by running full suite: 91 tests, 0 failures).

Human Verification Required

None. All security properties are verifiable programmatically:

• JWT token signing and validation: covered by unit tests
• Bootstrap token constant-time comparison: code inspection confirms MessageDigest.isEqual()
• Ed25519 signature verification: SseSigningIT verifies end-to-end using Signature.getInstance("Ed25519") with public key
• SecurityFilterChain endpoint protection: SecurityFilterIT exercises the full HTTP stack
