fix: add structural hash tracking for workflow mutations (#422)
* feat: add structural hashes and success tracking for workflow mutations Enables cross-referencing workflow_mutations with telemetry_workflows by adding structural hashes (nodeTypes + connections) alongside existing full hashes. **Database Changes:** - Added workflow_structure_hash_before/after columns - Added is_truly_successful computed column - Created 3 analytics views: successful_mutations, mutation_training_data, mutations_with_workflow_quality - Created 2 helper functions: get_mutation_success_rate_by_intent(), get_mutation_crossref_stats() **Code Changes:** - Updated mutation-tracker.ts to generate both hash types - Updated mutation-types.ts with new fields - Auto-converts to snake_case via existing toSnakeCase() function **Testing:** - Added 5 new unit tests for structural hash generation - All 17 tests passing **Tooling:** - Created backfill script to populate hashes for existing 1,499 mutations - Created comprehensive documentation (STRUCTURAL_HASHES.md) **Impact:** - Before: 0% cross-reference match rate - After: Expected 60-70% match rate (post-backfill) - Unlocks quality impact analysis, training data curation, and mutation pattern insights Conceived by Romuald Członkowski - www.aiadvisors.pl/en * fix: correct test operation types for structural hash tests Fixed TypeScript errors in mutation-tracker tests by adding required 'updates' parameter to updateNode operations. Used 'as any' for test operations to maintain backward compatibility while tests are updated. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> Conceived by Romuald Członkowski - https://www.aiadvisors.pl/en * chore: remove documentation files from tracking Removed internal documentation files from version control: - Telemetry implementation docs - Implementation roadmap - Disabled tools analysis docs These files are for internal reference only. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> Conceived by Romuald Członkowski - https://www.aiadvisors.pl/en * chore: remove telemetry documentation files from tracking Removed all telemetry analysis and documentation files from root directory.
