Rene Cannao	b3edc6524b	fix: Escape SQL strings in harvest_view_definitions ... Add escape_sql_string() helper function that doubles single quotes to prevent SQL injection when strings are used in SQL string concatenation. Update harvest_view_definitions to use this function for view_def, schema_name, and view_name. This prevents SQL injection in the UPDATE statement that stores view definitions in the catalog.

Rene Cannao	6835713f11	fix: Correct column indexes in build_quick_profiles ... Fix off-by-one errors in row->fields indices. The SELECT clause returns: object_id(0), schema_name(1), object_name(2), object_type(3), engine(4), table_rows_est(5), data_length(6), index_length(7), has_primary_key(8), has_foreign_keys(9), has_time_column(10) But the code was reading from fields[3..9] instead of [4..10]. Added comment documenting the correct column order. Addresses coderabbitai review comment.	3 months ago
Rene Cannao	bd6d34f52b	fix: Address SQL injection vulnerabilities from PR #26 review ... - lib/MySQL_Catalog.cpp: Convert search/list/remove to use SQLite prepared statements instead of string concatenation for user parameters - lib/RAG_Tool_Handler.cpp: Add escape_fts_query() function to properly escape single quotes in FTS5 MATCH clauses; update all FTS and vector MATCH queries to use escaped values - lib/Static_Harvester.cpp: Add is_valid_schema_name() validation function to ensure schema names only contain safe characters (alphanumeric, underscore, dollar sign) before using in INFORMATION_SCHEMA queries - lib/Query_Tool_Handler.cpp: Add clarifying comments to validate_readonly_query explaining the blacklist (quick exit) + whitelist (allowed query types) approach - Remove backup file lib/Anomaly_Detector.cpp.bak Addresses gemini-code-assist review comments from PR #26.	3 months ago

Rene Cannao	6f23d5bcd0	feat: Implement two-phase schema discovery architecture ... Phase 1 (Static/Deterministic): - Add Discovery_Schema: SQLite catalog with deterministic and LLM tables - Add Static_Harvester: MySQL INFORMATION_SCHEMA metadata extraction - Harvest schemas, objects, columns, indexes, foreign keys, view definitions - Compute derived hints: is_time, is_id_like, has_pk, has_fks, has_time - Build quick profiles and FTS5 indexes Phase 2 (LLM Agent): - Add 19 new MCP tools for two-phase discovery - discovery.run_static: Trigger ProxySQL's static harvest - Catalog tools: init, search, get_object, list_objects, get_relationships - Agent tools: run_start, run_finish, event_append - LLM tools: summary_upsert, relationship_upsert, domain_upsert, etc. Files: - include/Discovery_Schema.h, lib/Discovery_Schema.cpp - include/Static_Harvester.h, lib/Static_Harvester.cpp - include/Query_Tool_Handler.h, lib/Query_Tool_Handler.cpp (updated) - lib/Makefile (updated) - scripts/mcp/DiscoveryAgent/ClaudeCode_Headless/prompts/ - scripts/mcp/DiscoveryAgent/ClaudeCode_Headless/two_phase_discovery.py	3 months ago
