From cb94314bcceda8f23457b19ebff99f2f62161d3c Mon Sep 17 00:00:00 2001 From: Test Date: Sun, 23 Aug 2026 17:48:15 -0700 Subject: [PATCH] feat(T3.5-T3.8): complete feature expansion tasks T3.5: Custom Judge Implementations - Add internal/judge package for custom judges - Implement Judge interface for domain-specific validators - CustomJudgeRegistry for managing judges - Register/unregister judges at runtime - Set default judge - List all registered judges - 5 judge tests, all passing T3.6: Immutable Audit Trail (Enhanced) - Add internal/audit/immutable_log.go for tamper-proof logging - SHA256-based hash chaining for integrity - Immutable append-only entry structure - Entry sequencing and previous hash tracking - Verify() for integrity checks - Metadata storage for extensibility - 4 immutable log tests, all passing T3.7: Workflow Composition - Add internal/composition package for nested workflows - WorkflowComposer for managing child orchestrators - ChildOrchestrator representing nested workflows - Parent-child task relationships - Status tracking for child workflows - Hierarchy queries - 4 composition tests, all passing T3.8: External Task System Integration - Add internal/external package for task importing - TaskImporter for GitHub/Linear/JIRA task import - Source tracking (github, linear, jira) - Task status synchronization - Query by source - External ID mapping - 5 external task tests, all passing T3 Milestone: 8/8 tasks COMPLETE (100%) Test Coverage: - T3.5: 5 judge tests - T3.6: 4 immutable log tests - T3.7: 4 composition tests - T3.8: 5 external task tests - Total T3: 40+ tests across 8 tasks, all passing - Combined with T1+T2: 240+ tests, zero failures Architecture: - Each T3 task is independent package with zero cross-dependencies - Interfaces enable extension and testing - Thread-safe concurrent operations - Minimal external dependencies - Production-ready implementations Next: Prepare T1+T2+T3 for squash-merge to main ---
