From 6a681509f30334bad8aacc39f2c0927b37249136 Mon Sep 17 00:00:00 2001 From: Ben West Date: Wed, 18 Mar 2026 19:49:49 -0700 Subject: [PATCH] feat: add database-level production safety checks (GAP-SYNC-047) Adds multi-layer protection against running destructive tests on production: 1. Pre-flight check (hooks.js): Verifies NODE_ENV=test before any DB connection 2. Database name check: Requires 'test' substring in database name 3. Entry count threshold: Refuses if database has >100 entries (configurable) Environment Variables: - TEST_SAFETY_MAX_ENTRIES: Max entries before refusing (default: 100) - TEST_SAFETY_REQUIRE_TEST_DB: Require 'test' in DB name (default: true) - TEST_SAFETY_SKIP: Emergency bypass for all checks (default: false) Files: - tests/lib/production-safety.js: Core safety check module - tests/00_production-safety.test.js: Runs first to gate test suite - tests/production-safety.test.js: Unit tests for safety module - tests/hooks.js: Updated to use new module This addresses concerns about users with 'test' in production DB names by adding the entry count threshold as a secondary safety measure.
