pristine-sweep-drift-accumulates-without-active-resolution

The nightly pristine-sweep cron logged the same two findings (MEMORY.md over 130 lines, CLAUDE.md over 45 lines) for 4 consecutive nights, generating stale [DRIFT] entries that cluttered session-learnings. Sweep findings must be resolved in the next available session; unresolved entries compound into false-signal noise that masks new real drift.
