D-1 Verification Report

Date: 2026-03-29 Branch: culurien

PART 1: BUILD & TEST

Builds

• Linux AMD64 agent: PASS
• Linux AMD64 server: PASS

Test Counts

• Agent: system(7) + client(2) + logging(2) + scanner(19) + internal(4) + circuitbreaker(3) + crypto(14) = 51 tests
• Server: middleware(12) + handlers(17) + database(9) + migrations(10) + queries(3) + services(4) = 55 tests
• Total: 106 tests, all PASS, 0 FAIL, 0 SKIP

D-1 State-Change Confirmation

All 6 FAIL-NOW tests flipped to PASS. All 9 PASS-NOW tests updated correctly.

---

PART 2: REGISTRATION FALLBACK (F-D1-1) — PASS

• NO "unknown-" string in registration path (grep: zero matches in main.go)
• Only machine ID source: system.GetMachineID()
• Failure: log.Fatalf("[ERROR] [agent] [registration] machine_id_unavailable...") — clean abort
• Format consistency: both registration and runtime call system.GetMachineID() → both get SHA256 hex
• No divergence possible in fixed code

---

PART 3: REBIND ENDPOINT (F-D1-2) — PASS

• Route: POST /api/v1/admin/agents/:id/rebind-machine-id (main.go:604)
• Auth: admin group (WebAuthMiddleware + RequireAdmin)
• Input validation: exactly 64 chars, lowercase hex [0-9a-f] only
• Uppercase hex → 400 rejected (not normalized — consistent with GetMachineID output)
• Audit: [INFO] [server] [admin] agent_machine_id_updated agent_id=%s old_id=%s new_id=%s admin_user=%s
• UpdateMachineID uses parameterized query ($1, $2)

---

PART 4: DEAD CODE DELETION (F-D1-3) — PASS

• example_integration.go: file not found (deleted)
• Zero references remain in codebase
• Logging package compiles cleanly

---

PART 5: WINDOWS REDUNDANT RETRY (F-D1-4) — PASS

• getWindowsMachineID() no longer calls machineid.ID() (grep: zero in function body)
• Falls through directly to generateGenericMachineID() which produces SHA256 hash
• Windows reinstall comment present with rebind endpoint reference

---

PART 6: LOGGING FORMAT (F-D1-5) — PASS

• fmt.Printf in client.go: only at line 94 (event buffer, NOT machine ID)
• Machine ID error uses log.Printf("[WARNING] [agent] [client] machine_id_error...")
• log import present, fmt retained for other uses

---

PART 7: EDGE CASES

• Existing "unknown-" agents: Will be locked out on upgrade. Migration guide in D1_Fix_Implementation.md covers this with SQL query and rebind instructions.
• Runtime GetMachineID failure: client.go sets machineID = "" → server rejects with 403 "missing machine ID header" → agent can't check in but doesn't crash. Operator must fix underlying machine ID issue.
• Rebind uppercase hex: Rejected with 400 (lowercase only). Consistent with hashMachineID() output which is lowercase.

---

PART 8: ETHOS COMPLIANCE

• Registration abort: [ERROR] [agent] [registration]
• Client error: [WARNING] [agent] [client]
• Rebind audit: [INFO] [server] [admin]
• No emojis in modified files
• Rebind behind WebAuthMiddleware + RequireAdmin
• Input validation prevents malformed IDs
• Registration fails cleanly
• GetMachineID() is idempotent
• No banned words

---

PART 9: PRE-INTEGRATION CHECKLIST

• Linux AMD64 builds pass
• All 106 tests pass, zero regressions
• All 6 D-1 FAIL-NOW tests now PASS
• "unknown-" fallback removed
• Registration aborts on failure
• client.go logs warning (not empty string crash)
• Rebind endpoint with admin auth and validation
• Audit logging with old + new IDs
• example_integration.go deleted
• Windows retry removed
• Windows reinstall documented
• fmt.Printf replaced in client.go
• Operator migration guide complete
• ETHOS compliant

---

ISSUES FOUND
