+The company should get smarter over time:
+- After solving a hard problem, document the solution as a lesson_learned comment
+- After making an important decision, document the rationale and alternatives considered
+- When onboarding new agents, share relevant past decisions and lessons
+- Periodically review past incidents and ensure fixes are still in place
+- Capture "best practices" that emerge from repeated successes
