Signal Handling Imports** (lines 9-10)\n- Added `tokio::signal::unix::{SignalKind, signal as unix_signal}` for SIGINT/SIGTERM\n- Added `Instant` from `std::time` for elapsed-time tracking\n\n**2. `poll_status()` - Real HTTP Implementation** (lines 194-243)\n- Replaced Phase 1 stub with production `GET /api/v1/enroll/status/{token}`\n- Handles HTTP 200 (parse status), 404 (token invalid), 429 (rate limited), 5xx (server error)\n- Returns deserialized `EnrollmentStatusResponse` enum variant\n\n**3. `poll_for_approval()` - Polling Loop** (lines 246-378)\n- **Timeout enforcement**: Hard cap at 1440 attempts (24h @ 60s), clamps config values exceeding this\n- **Signal racing**: `tokio::select!` races poll request against SIGINT/SIGTERM via `unix_signal().recv()`\n- **Status handling**: Pending → sleep & retry, Approved → extract `PkiBundle`, Denied/NotFound → immediate error\n- **Transient error recovery**: Network failures and 5xx errors log warning and retry on next interval\n- **Logging throttling**: Progress logged every 10th attempt or after 300s elapsed (whichever comes first)\n- **Security**: Polling token never appears in log messages\n\n**4. Signal Helper Methods** (lines 380-390)\n- `setup_sigint()` → `unix_signal(SignalKind::interrupt())`\n- `setup_sigterm()` → `unix_signal(SignalKind::terminate())`\n\n### Verification Results\n```\ncargo check   →  zero errors, zero warnings\ncargo test    →  all 46 tests passed (including 7 enroll::client tests)\n```\n\n### Cross-Distro Compatibility\n- All target distros (Debian/Ubuntu, RHEL/CentOS/Fedora, Alpine, Arch Linux)...

These tests validate registration, polling loop behavior, and error handling.\n\n### Read These Files First\n- `src/enroll/client.rs` - EnrollmentClient with register() and poll_for_approval()\n- `src/enroll/mod.rs` - run_enrollment() orchestration function\n- `tests/integration/` - existing integration test patterns in the project\n- `Cargo.toml` - check for existing test dependencies (wiremock, actix-web test utils)\n\n### Test File Location\nCreate: `tests/integration/enrollment_test.rs`\n\n### Required Tests\n\n1. **Mock Manager Server Setup:**\n   - Use a lightweight HTTP server (actix-web test server or similar) that simulates the manager API\n   - Endpoints to mock:\n     - `POST /api/v1/enroll` \u2192 returns `{\"polling_token\": \"test_token_123\"}` with 202\n     - `GET /api/v1/enroll/status/test_token_123` \u2192 returns status variants based on test scenario\n\n2. **Test: Successful Enrollment Flow:**\n   - Mock server returns pending twice, then approved with dummy PEM certs\n   - Verify register() receives correct payload structure\n   - Verify poll_for_approval() returns PkiBundle with expected cert fields\n   - Verify 3 total requests to status endpoint (2 pending + 1 approved)\n\n3. **Test: Denied Enrollment:**\n   - Mock server returns `{\"status\": \"denied\"}` on first poll\n   - Verify poll_for_approval() returns appropriate error\n   - Verify no further polling attempts after denial\n\n4. **Test: Token Not Found (Expired):**\n   - Mock server returns `{\"status\": \"not_found\"}` on first poll\n   - Verify poll_for_approval() returns appropriate error\n\n5. **Test: Max Attempts Timeout:**\n   - Mock server always returns `{\"status\": \"pending\"}`\n   - Call with max_attempts=3\n   - Verify polling stops after 3 attempts with timeout error\n\n6. **Test: Rate Limit Handling (429):**\n   - Mock server returns 429 on first registration attempt\n   - Verify register() returns descriptive error with retry guidance\n\n7. **Test: Registration Payload Structure:**\n   - Capture the POST body sent to /api/v1/enroll\n   - Verify it contains machine_id, fqdn, ip_address, os_details fields\n   - Verify all fields are non-empty valid values\n\n### Test Structure\n```rust\nuse linux_patch_api::enroll::client::EnrollmentClient;\nuse linux_patch_api::enroll::client::{EnrollmentResponse, EnrollmentStatusResponse, PkiBundle};\n// ... test functions with mock server setup\n```\n\n### Verification\n- `cargo test --test enrollment_test` passes all tests\n- Tests compile on current system (Kali Linux in Docker)\n- Mock server starts and stops cleanly within test lifecycle\n- No external network dependencies (all mocking is local)\n\n### Output Contract\n- `tests/integration/enrollment_test.rs` created with comprehensive enrollment integration tests\n- All tests pass when run with `cargo test`\n- Tests verify registration payload structure, polling behavior, error handling, and timeout enforcement"}, "timestamp": 1778965257}, {"type": "tool", "heading": "icon://construction A1: Using tool 'text_editor'", "content": "/a0/usr/projects/linux_patch_api/src/enroll/client.rs 467 lines\n>>>\n  1 //!
