# Phase 4: Security Verification Report

**Phase Goal:** All server communication is authenticated and integrity-protected, with JWT for API access and Ed25519 signatures for pushed configuration
**Verified:** 2026-03-11T20:50:00Z
**Status:** PASSED
**Re-verification:** No — initial verification

## 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

### Test Suite Result

Full `mvn verify` with `CAMELEER_AUTH_TOKEN=test-bootstrap-token`:

| Suite | Tests | Result |
|-------|-------|--------|
| Unit tests (JwtServiceTest, Ed25519SigningServiceTest, BootstrapTokenValidatorTest, SsePayloadSignerTest, ElkDiagramRendererTest) | 36 | PASS |
| Security ITs (SecurityFilterIT, BootstrapTokenIT, RegistrationSecurityIT, JwtRefreshIT, SseSigningIT) | 20 | PASS |
| All other controller/storage ITs | 35 | PASS |
| **Total** | **91** | **PASS** |
