From 7557e127a6fee0426d2772275ca27f1413da0ef1 Mon Sep 17 00:00:00 2001 From: jpetree331 Date: Sun, 29 Mar 2026 18:43:00 -0400 Subject: [PATCH] verify: integration verification pass Fixed seam issues found during cross-series verification: - Add path traversal guard to DownloadAgent signed-package path - Replace fmt.Printf DEBUG/Warning in updates.go with log.Printf - Replace 11 emoji in subsystem_handlers.go daemon logs with ETHOS format All series verified to work together correctly. 170 tests pass. Full ETHOS compliance confirmed. 3 cross-platform builds pass (linux-amd64, linux-arm64, windows-amd64).

The Windows service does not rotate its cached public key. This is documented as DEV-030 — the 24h TTL cache is the workaround. + +### 3b. Command Verification on Windows — PASS +`commandHandler` is properly initialized via `orchestrator.NewCommandHandler()` at `windows.go:126`. `ProcessCommand` called at line 297 in the polling loop. Same verification path as `main.go`. Fail-fast on initialization failure (line 130). + +--- + +## Part 4: B-Series x E-Series Seams + +### 4a.

No transaction needed. + +### 4b. expires_at + Upgrade Commands — PASS +`CreateCommand` in `commands.go:31-34` sets `expires_at = NOW() + 4h` unconditionally for all commands including `update_agent`. The upgrade watchdog runs for 5 minutes — well within the 4h TTL. + +### 4c. Retry Count + Update Commands — PASS +`retry_count` incremented on re-delivery, capped at 5. After 5 retries, commands become permanently failed. This is acceptable for upgrade commands — 5 retries means the agent has failed to accept the upgrade 5 times (likely a persistent issue requiring manual intervention). + +--- + +## Part 5: D-Series x Upgrade Seams + +### 5a. Machine ID in Upgrade Commands — PASS +The `agent_id` used in command signatures is the server-assigned UUID from the `agents` table (set at registration). `MachineID` is used only for registration-time binding, not as the ongoing identity. No UUID confusion. + +### 5b. Machine ID After Upgrade — PASS +After upgrade + restart, the agent loads `AgentID` from the config file (not from `GetMachineID()`). `GetMachineID()` is only called during `-register`. The persisted UUID identity is stable across upgrades. + +--- + +## Part 6: Installer x Upgrade Seams + +### 6a. Checksum Header in Upgrade Flow — PASS (documented gap) +`downloadUpdatePackage()` does NOT read the `X-Content-SHA256` HTTP header. It uses the checksum from the command's `params["checksum"]` field exclusively. Both values originate from the same DB record (`agent_update_packages.checksum`), so they should match. Not a bug — the params checksum is signed, making it more trustworthy than an unsigned HTTP header. + +### 6b. Architecture in Upgrade Commands — PASS +`agent_updates.go` reads `agent.OSType` and `agent.OSArchitecture` from the DB to construct the platform string. The `isPlatformCompatible` check validates the requested platform against the agent's actual platform before accepting. + +### 6c. Binary Path Sanitization + Upgrade — PASS (fixed during verification) +`DownloadAgent` had no path traversal guard on the signed-package code path (`signedPackage.BinaryPath` was used directly). **Fixed:** Added `filepath.Abs` + `allowedDir` prefix check matching `DownloadUpdatePackage`.
