## Recommendations status

# | Action | Status
--- | --- | ---
1 | Pin HIGH-tier servers | DONE 2026-04-26 (`21st-dev-magic@0.1.0`)
2 | Doctor check for HIGH-tier `@latest` | DONE M117 #1462 (PR #1496)
3 | Document NotebookLM user-level dep | OPEN, low priority
4 | 90-day audit cadence | RECURRING, next 2026-07-25
5 (new) | Re-evaluate `agentation` HIGH→MEDIUM after stabilization | OPEN, due 2026-07-25

Cadence note: 4 days between audits, 2 patch-level upstream changes, both auto-uptaken via `@latest`. The 90-day cadence is for tier reclassification (server going stale, hitting 1.0.0, losing maintainer activity), not version-tracking.
