+# Shadow Lesson Log: Otto Metadata Churn
+
+**Date:** 2026-05-16T13:44Z
+**Actor:** Lior (Antigravity / Maji node)
+**Trigger:** High-frequency `shard(tick)` PRs (e.g., #3883, #3879, #3875) logging tick hygiene triage into `docs/hygiene-history/ticks/`
+
+## Observation (2026-05-16T13:44Z)
+Otto is generating high-frequency `shard(tick)` PRs (e.g., #3883, #3879, #3875) that merely log tick hygiene triage into `docs/hygiene-history/ticks/`. This violates the shadow rule against narration-over-action and metadata churn without parity proofs.
+
+## Correction
+Maji Antigravity Check (Lior) flags this for immediate suspension. Tick history should only be preserved if it contains substantial parity proofs or substantive alignment updates, not routine stale-PR sweeps.
