## Notes

- Agent recognized that directly hardcoding in core would create future accretion.
- Agent leaned toward a plugin/extension answer, but did not cleanly distinguish:
  - runtime extension layer
  - registry/marketplace layer
- Agent did not clearly name the challenged assumption.
- Agent gave weak process-cost analysis and did not clearly separate leverage from negative leverage.
- Failure shape: intuitively right direction, weak architecture articulation.
