From 6f9de3c734a7fc5cc28490f1e30d62c4c4ca155a Mon Sep 17 00:00:00 2001 From: fullsend-code <278716306+fullsend-ai-coder[bot]@users.noreply.github.com> Date: Mon, 22 Jun 2026 03:26:27 +0000 Subject: [PATCH] feat(#3299): runtime configuration engine with Zod validation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements the runtime configuration engine for boost-backend: - RuntimeConfigResolver: two-layer config resolution (DB override → YAML baseline) with cacheService (30s TTL, immediate invalidation on write). Single cache layer, no duplicate wrappers. - AdminConfigService: DB-backed config overrides using the boost_admin_config table. Validates all writes against Zod schemas and enforces configScope (yaml-only fields rejected for DB writes). - Zod schemas as single source of truth: all 15 admin-configurable fields defined with schema, configScope annotation (yaml-only, db-overridable, db-only), and descriptions. config.d.ts generated from the same schema definitions. - Credential encryption: AES-256-GCM encryption for sensitive DB-stored values (e.g., DevSpaces credentials) with configurable encryption secret. - Schema version tracking: stores schema version alongside DB values. On startup, re-validates all stored values against current schemas and removes invalid overrides (restoring YAML baseline). - Plugin wired with coreServices.cache and coreServices.database dependencies, satisfying the cache-from-day-one architecture rule.
