From ab4c967a9709a5b75c9350d9c989b4cf09962fa1 Mon Sep 17 00:00:00 2001 From: Gulshan Yadav Date: Sat, 10 Jan 2026 18:11:13 +0530 Subject: [PATCH] feat(database): complete Phase 10 Database Gateway Add HTTP REST API gateway for Synor Database L2: - Gateway server with Axum HTTP framework - API key authentication with permissions and rate limiting - Full REST endpoints for all database models: - Key-Value: GET/PUT/DELETE /kv/:key, POST /kv/batch - Documents: CRUD operations, MongoDB-style queries - Vectors: embedding insert, similarity search - Time-series: metrics recording and queries - Usage metering for billing integration - CORS and request timeout configuration All 51 tests passing.
