+## Core Implementation Commits
+
+### Commit: 975de8d
+**Message:** Add core Python modules (699 lines total)
+
+**Files:**
+- triangle_test.py
+- guardian.py
+- context_router.py
+- canonical_json.py
+- identity_manager.py
+
+**Description:** Initial implementation of core Python modules demonstrating reduction to practice.
+
+**Cross-Reference:** This commit is cross-referenced in the manifest and blockchain proof for audit and legal traceability.
+
+---
+
+## Automation Guidelines
+
+For future updates, automate provenance tracking by recording:
+- Commit hashes
+- Timestamps
+- Affected files
+- Commit messages
+
+Record this information in both:
+1. This manifest file
+2. Blockchain-anchored records
