🔍 Key Insights

User Feedback Integration

Original Assumption: Databento API key was invalid User Correction: "We used the key before, this was working before" Lesson: Always verify assumptions against existing evidence (377 .dbn files proved key was valid)

Build System Hygiene

Problem: Stale build cache causing mysterious compilation errors Solution: cargo clean -p data resolved immediately Lesson: When facing inexplicable compilation errors, check for stale cache first

Test Infrastructure Quality

Achievement: 9/9 TLI ML trading tests pass with real authentication Quality Indicators:

• Real JWT token generation (not mocks)
• Cross-process encryption key sharing
• Per-test isolation with XDG_CONFIG_HOME
• Serial execution for stability

Anti-Workaround Compliance: 100%

• ✅ NO STUBS
• ✅ NO MOCKS
• ✅ NO PLACEHOLDERS
• ✅ REAL IMPLEMENTATIONS
