From 583e6b7ea27e271d284a5d0eeea217b6d5a4e1a4 Mon Sep 17 00:00:00 2001 From: Jeffrey Phillips Freeman Date: Sun, 8 Mar 2026 20:26:19 +0000 Subject: [PATCH] feat(correcting-plans): implement Predictive Error Prevention (Layer 4) with Error Pattern Database Implement spec-mandated Layer 4 Predictive Error Prevention system: - ErrorPattern domain model with pattern text, historical failures, preventive checks, frequency tracking, and keyword-based matching. - ErrorPatternRepository with in-memory CRUD + context-matching query. - ErrorPatternService with record_failure(), match_patterns(), and get_statistics() methods. - Wire into plan execution via plan_lifecycle_service pre-execution hook. - Add error pattern statistics to CLI diagnostics output. Behave BDD: 11 scenarios covering recording, matching, formatting, stats. Robot Framework: 3 integration smoke tests. ASV benchmarks: pattern matching performance.
