From 76808086d202ea21cd7c4eeb1e9147ed1b7542b0 Mon Sep 17 00:00:00 2001 From: Oliver Le Date: Thu, 9 Apr 2026 10:36:46 -0700 Subject: [PATCH 01/26] feat: behavioral extraction + pattern tracking for learning pipeline New: behavioral_extractor.py - 12-archetype sentence-level extraction for actionable lesson descriptions - Replaces word-diff summaries with imperative instructions - Template-based with upgrade path for LLM refinement New: correction_patterns table (meta_rules_storage.py) - Cross-session pattern tracking with batch upsert - Graduation candidate query for repeated patterns Changed: _core.py - brain.correct() uses behavioral_extractor as primary extraction path - Falls back to keyword templates New: test_pipeline_e2e.py (12 tests) - Pattern tracking, correction logging, injection formatting - Cloud-dependent tests skip on CI 1699 tests passing, 0 failures.
