What is scheduled habit review?

Scheduled habit review is a concept in personal epistemology: Agents need regular maintenance — scheduled reviews prevent gradual degradation.

Example: You built a morning routine six months ago. It worked brilliantly for the first three months — you woke at 6 AM, meditated, journaled, exercised, and started deep work by 8:30. Then your schedule shifted. You started a new project with 9 AM standups. Your gym changed its early class times. Winter arrived and waking at 6 felt brutal. You never formally reviewed the routine — you just started skipping pieces. The meditation dropped first, then the journaling. By month five, the 'morning routine' was just waking up and checking email. The agent didn't fail catastrophically. It degraded silently, one small erosion at a time, because nothing in your system scheduled a maintenance review that would have caught the drift at month three and prompted an adjustment.

This concept is part of Phase 30 (Agent Lifecycle) in the How to Think curriculum, which builds the epistemic infrastructure for agent lifecycle.
