|
## Part 2: A-Series x B-Series Seams
|
|
|
|
### 2a. Command Signing + Transaction Safety — PASS
|
|
`signAndCreateCommand()` in `agents.go:49-77` signs first, then stores. If signing fails, the function returns immediately — no partial command in DB. The `InstallUpdate` handler in `agent_updates.go:234` correctly checks the error and rolls back the `updating` flag.
|
|
|
|
**Note:** Unsigned commands are silently allowed when signing is disabled. This is by design (optional signing), not a bug.
|
|
|
|
### 2b. Key Rotation + Migration Safety — PASS
|
|
Startup order confirmed in `main.go`:
|
|
1. Lines 190-194: `db.Migrate()` — fatal on failure
|
|
2. Lines 220-235: `services.NewSigningService()` initialized
|
|
3. Lines 241-248: `signingService.InitializePrimaryKey()` called
|
|
|
|
Migrations complete before signing service touches the DB.
|
|
|
|
### 2c. Retry Command + signAndCreateCommand — PASS
|
|
`signAndCreateCommand` confirmed present in both retry paths:
|
|
- `update_handler.go:765`
|
|
- `updates.go:813`
|
|
|
|
F-5 fix (retry must re-sign) is intact.
|
|
|

|
|
|
|
## Part 3: A-Series x C-Series Seams
|
|
|
|
### 3a. Key Cache on Windows — WARNING (known gap DEV-030)
|
|
`ShouldRefreshKey` is NOT called in `windows.go`. Only appears as a TODO comment at line 164-168. 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. Security Audit Trail Transaction Safety — PASS
|
|
`GetSecurityAuditTrail` is read-only (calls `GetAuditTrail(100)` → SELECT query). 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`. Traversal attempts now logged at `[ERROR] [server] [downloads] path_traversal_attempt_signed`.
|

|
## Part 7: End-to-End Flow Traces
|
|
|
|
### 7a. Fresh Agent Registration Flow
|
|
|
|
| Step | Description | Status |
|
|
|------|-------------|--------|
|
|
| 1 | Installer generates one-liner with arch detection | CONFIRMED — `uname -m` / `$env:PROCESSOR_ARCHITECTURE` |
|
|
| 2 | curl \| bash runs on target | CONFIRMED — template renders complete script |
|
|
| 3 | Binary downloaded + checksum verified | CONFIRMED — `X-Content-SHA256` + `sha256sum` |
|
|
| 4 | Agent started with `-register` flag | CONFIRMED — `registerAgent()` at main.go:311 |
|
|
| 5 | `GetMachineID()` — SHA256 hash | CONFIRMED — line 427, `log.Fatalf` on failure |
|
|
| 6 | `POST /agents/register` in transaction | CONFIRMED — B-2 fix wraps in `tx.Beginx()` |
|
|
| 7 | JWT issued with `issuer=redflag-agent` | CONFIRMED — A-3 fix |
|
|
| 8 | Server public key cached with TTL | CONFIRMED — `fetchAndCachePublicKey()` line 473 |
|
|
| 9 | Polling with proportional jitter | CONFIRMED — B-2 fix, `maxJitter = pollingInterval/2` |
|
|
|
|
### 7b. Command Approval + Delivery Flow
|
|
|
|
| Step | Description | Status |
|
|
|------|-------------|--------|
|
|
| 1 | Agent reports available update | CONFIRMED |
|
|
| 2 | Admin approves in dashboard | CONFIRMED |
|
|
| 3 | `signAndCreateCommand()` — v3 format, key_id, expires_at | CONFIRMED |
|
|
| 4 | Agent polls — `SELECT FOR UPDATE SKIP LOCKED` | CONFIRMED — `GetPendingCommandsTx` |
|
|
| 5 | Dedup check + key rotation + v3 verification | CONFIRMED |
|
|
| 6 | Agent executes update | CONFIRMED |
|
|
| 7 | Agent reports result | CONFIRMED |
|
|
|
|
### 7c. Agent Upgrade Flow
|
|
|
|
| Step | Description | Status |
|
|
|------|-------------|--------|
|
|
| 1 | Admin clicks Update | CONFIRMED |
|
|
| 2 | Frontend generates nonce | CONFIRMED — U-4 fix for bulk too |
|
|
| 3 | `POST /agents/{id}/update` creates command | CONFIRMED |
|
|
| 4 | Command signed v3 format | CONFIRMED |
|
|
| 5 | `expires_at = NOW() + 4h` | CONFIRMED |
|
|
| 6 | Agent polls, receives `update_agent` | CONFIRMED |
|
|
| 7 | Verifies command signature | CONFIRMED |
|
|
| 8 | `downloadUpdatePackage()` with 5min timeout | CONFIRMED — U-8 fix |
|
|
| 9 | SHA-256 checksum verified | CONFIRMED |
|
|
| 10 | Ed25519 binary signature verified | CONFIRMED |
|
|
| 11 | Backup `.bak`, atomic rename, restart | CONFIRMED |
|
|
| 12 | Watchdog polls, confirms version | CONFIRMED — uses string equality (documented gap) |
|
|
| 13 | Success: `.bak` deleted | CONFIRMED |
|
|
|
|
**Known gap (7c step 12):** Watchdog uses `agent.CurrentVersion == expectedVersion` (string equality) instead of `CompareVersions`. Would fail on `"v0.1.4"` vs `"0.1.4"` mismatch. Low risk since both sides use the same version string format.
|
|
|

|
|
|
|
## Part 8: Migration Sequence
|
|
|
|
### 8a. Migration Files
|
|
32 `.up.sql` files: 001, 003-030 (with letter variants 009b, 012b, 023a). Migration 002 is missing (gap) — likely intentionally deleted. All end at 030.
|
|
|
|
### 8b. Migrations 025-030 — PASS
|
|
All 6 present with correct names and content.
|
|
|
|
### 8c. Idempotency — PASS
|
|
All CREATE TABLE/INDEX use `IF NOT EXISTS`. INSERT uses `ON CONFLICT DO NOTHING`. ALTER TABLE uses `ADD COLUMN IF NOT EXISTS`.
|
|
|
|

|
|
|
|
## Part 9: ETHOS Final Sweep
|
|
|
|
### 9a. Emoji in Go Production Logs — PASS (after fix)
|
|
**Fixed during verification:** 11 emoji in `subsystem_handlers.go` `log.Printf` calls replaced with ETHOS-format structured logging. Remaining emoji in `main.go` lines 294-322 and 691-697 are user-facing terminal/CLI output (registration success banners) — exempt per DEV-039.
|
|
|
|
### 9b. fmt.Printf for Logging — PASS (after fix)
|
|
**Fixed during verification:** 5 `fmt.Printf` calls in `updates.go` (1 DEBUG, 4 Warning) replaced with `log.Printf` using ETHOS format. Remaining `fmt.Printf` in `main.go` and `config.go` are startup banners and config loading — acceptable.
|
|
|
|
### 9c. Banned Words — PASS
|
|
Zero results for "enhanced", "seamless", "robust", "production-ready", "revolutionary".
|
|
|
|
### 9d. Silenced Errors — PASS
|
|
Zero `_ = err` patterns found in production code.

## Issues Found and Fixed
|
|
|
|
| # | Severity | Issue | Fix |
|
|
|---|----------|-------|-----|
|
|
| 1 | HIGH | `DownloadAgent` signed-package path had no path traversal guard | Added `filepath.Abs` + `allowedDir` prefix check |
|
|
| 2 | MEDIUM | `updates.go:191` had `fmt.Printf("DEBUG:...")` in production handler | Replaced with `log.Printf("[ERROR] [server] [updates]...")` |
|
|
| 3 | MEDIUM | `updates.go:264,278,306,311` used `fmt.Printf("Warning:...")` | Replaced with `log.Printf("[WARNING] [server] [updates]...")` |
|
|
| 4 | LOW | `subsystem_handlers.go` had 11 emoji in `log.Printf` daemon logs | Replaced with ETHOS-format structured logging |
|

## Known Remaining Limitations (Not Bugs)
|
|
|
|
| # | Area | Limitation | Risk |
|
|
|---|------|-----------|------|
|
|
| 1 | Windows (DEV-030) | Key rotation not in Windows service polling loop | LOW — 24h TTL cache workaround |
|
|
| 2 | Upgrade watchdog | String equality instead of `CompareVersions` | LOW — both sides use same format |
|
|
| 3 | Migration 002 | Missing from sequence (gap between 001 and 003) | NONE — likely intentionally deleted |
|
|
| 4 | Upgrade checksum | Agent doesn't read `X-Content-SHA256` header (uses signed params instead) | NONE — params checksum is more trustworthy |
|
|
| 5 | main.go emoji | Registration/startup banners have emoji (user-facing, DEV-039 exempt) | NONE — intentional UX |
