-- Migration 008: RLM Schema
-- Creates tables for Recursive Language Models (RLM) integration
-- Provides chunking, buffering, and execution history storage

-- Use test namespace and database
USE NS test_rlm_e2e DB test_rlm_e2e;

-- RLM Chunks table (from documents)
-- Note: Using SCHEMALESS instead of SCHEMAFULL because:
--   1. SurrealDB auto-generates `id` field for all records
--   2. Explicit `id` field definition in SCHEMAFULL causes conflicts with CREATE queries
--   3. SCHEMALESS provides flexibility while still allowing indexes
DEFINE TABLE rlm_chunks SCHEMALESS;

-- Indexes for efficient queries (work with SCHEMALESS tables)
DEFINE INDEX idx_rlm_chunks_chunk_id ON TABLE rlm_chunks COLUMNS chunk_id UNIQUE;
DEFINE INDEX idx_rlm_chunks_doc_id ON TABLE rlm_chunks COLUMNS doc_id;

-- RLM Buffers table (pass-by-reference for large contexts)
DEFINE TABLE rlm_buffers SCHEMALESS;

-- Indexes for buffers
DEFINE INDEX idx_rlm_buffers_buffer_id ON TABLE rlm_buffers COLUMNS buffer_id UNIQUE;

-- RLM Execution History table (for learning)
DEFINE TABLE rlm_executions SCHEMALESS;

-- Indexes for execution history
DEFINE INDEX idx_rlm_executions_execution_id ON TABLE rlm_executions COLUMNS execution_id UNIQUE;
DEFINE INDEX idx_rlm_executions_doc_id ON TABLE rlm_executions COLUMNS doc_id;
