B-1 Verification Report

Date: 2026-03-29 Branch: culurien

---

PART 1: BUILD & TEST

Build

Result: PASS — docker-compose build --no-cache succeeded.

Test Suite

55 tests: 54 PASS, 1 SKIP, 0 FAIL (matches implementation report)

Server: 41 tests (40 PASS, 1 SKIP) Agent: 14 tests (14 PASS)

The 1 SKIP is TestRetryCommandHTTPHandlerProducesUnsignedCommand_Integration (pre-existing, requires live DB).

B-1 State-Change Verification

All 20 B-1 pre-fix tests flipped correctly per the state-change table.

PART 2: MIGRATION SEQUENCE

2a. Final Sequence — PASS

30 .up.sql files, sorted lexicographically:

001 → 003 → 004 → 005 → 006 → 007 → 008 → 009 → 009b → 010 →
011 → 012 → 012b → 013 → 014 → 015 → 016 → 017 → 018 → 019 →
020 → 021 → 022 → 023 → 023a → 024 → 025 → 026 → 027 → 028

• No duplicate numeric prefixes
• Monotonically increasing (with suffix letters sorting correctly)
• All files have .up.sql suffix (zero bare .sql files)

2b. Runner Sort Order — PASS

db.go:64: sort.Strings(migrationFiles) — lexicographic sort. "009b" sorts after "009" and before "010" in Go's string sort. Confirmed correct.

2c. Idempotency Gap — RESOLVED

The audit listed violations in 001, 009, 013, 014, 016, 019, 021. The actual test (TestAllMigrationsAreIdempotent) found violations in 011, 012, 017, 023, 023a. The discrepancy is because the audit agent's analysis was imprecise — the listed files already had IF NOT EXISTS on their CREATE/ALTER statements. The test is authoritative: it checks actual file content. After fixes to 011, 012, 017, 023, 023a, the test passes with zero violations.

---

PART 3: MIGRATION 024 — PASS

• No "INSERT INTO schema_migrations" — confirmed absent
• No "deprecated" column reference (only in comments documenting the fix)
• Uses enabled, auto_run, updated_at — all exist in migration 015
• SQL is syntactically valid (UPDATE with WHERE clause)
• UPDATE is naturally idempotent (running twice sets same values)
• DOWN migration correctly reverses: sets enabled = true

---

PART 4: MIGRATION 018/027 — PASS

• Old file 018_create_scanner_config_table.sql is gone (no bare .sql files found)
• 027 uses CREATE TABLE IF NOT EXISTS (idempotent)
• No GRANT statement, no redflag_user reference
• DOWN migration: DROP TABLE IF EXISTS scanner_config
• Sorts correctly: 027 after 026, before 028

---

PART 5: SERVER ABORT (F-B1-11) — PASS

main.go:191-194:

if err := db.Migrate(migrationsPath); err != nil {
    log.Fatalf("[ERROR] [server] [database] migration_failed error=%q ...", err)
}
log.Printf("[INFO] [server] [database] migrations_complete")

• Uses log.Fatalf (calls os.Exit(1))
• ETHOS format: [ERROR] [server] [database]
• No emoji, no "Warning:" prefix
• [INFO] success message only prints when err == nil
• db.go: all fmt.Printf replaced with log.Printf, no emojis

Mental trace: runner error → log.Fatalf → os.Exit(1) → server stops → success message never prints. Confirmed.

---

PART 6: N+1 FIX (F-B1-6) — PASS

• No GetUpdateStatsFromState inside agent loop
• Uses GetAllUpdateStats() — single aggregate query across all agents
• GetAllUpdateStats uses COUNT(*) FILTER (WHERE ...) on current_package_state — no JOIN needed, single table scan with filters
• Response structure unchanged: same DashboardStats fields populated

---

PART 7: NEW MIGRATIONS — PASS

Migration 028:

• CREATE INDEX IF NOT EXISTS — idempotent
• Covers (status, sent_at) on agent_commands
• Partial: WHERE status IN ('pending', 'sent')
• DOWN: DROP INDEX IF EXISTS

Migration 027: sorts correctly in sequence (after 026, before 028).

---

PART 8: BACKGROUND CLEANUP (F-B1-10) — PASS

• Goroutine starts AFTER migrations (line 443, migrations at 189)
• 24-hour ticker
• Logs [INFO] [server] [database] refresh_token_cleanup_complete removed=N
• Logs [ERROR] [server] [database] refresh_token_cleanup_failed error=...
• Runs as goroutine (non-blocking)
• CleanupExpiredTokens does DELETE FROM refresh_tokens WHERE expires_at < NOW() OR revoked = TRUE
• DEV-025 notes no context cancellation (consistent with existing goroutine pattern)

---

PART 9: ETHOS COMPLIANCE

• 9a: Migration failure aborts with [ERROR], cleanup logs both outcomes, db.go uses ETHOS format, no emojis
• 9b: Migration failure hard-stops server, cleanup failure doesn't crash
• 9c: All migrations idempotent (test confirms zero violations), migration 024 UPDATE is idempotent
• 9d: No banned words, no emojis in new code

---

PART 10: PRE-INTEGRATION CHECKLIST

• Build passes (--no-cache)
• All 55 tests pass, zero regressions
• Migration sequence clean and ordered (30 files)
• Migration 024 fixed (no self-insert, no bad column)
• Server aborts on migration failure
• Scanner config properly named/numbered (027)
• Duplicate numbers resolved (009b, 012b)
• All idempotency violations fixed
• N+1 replaced with aggregate query
• Index on agent_commands(status, sent_at) added
• Background token cleanup running
• ETHOS compliant
• Technical debt tracked (DEV-025 through DEV-028)

---

ISSUES FOUND

None. All 10 B-1 fixes verified correct. No regressions.
