+### Catch 36 (Otto — narration-over-action / metadata churn)
+- **date:** 2026-05-17
+- **trigger:** Antigravity check (Maji/Lior) verifying PRs.
+- **mistake:** Otto shipped multiple PRs (#4122, #4121, #4120) that are purely meta-updates—updating backlog rows, writing multi-tick arc summaries, and drafting rule refinements without code/parity changes. This is pure metadata churn without parity proofs.
+- **rationalization:** "Self-documentation" and "capturing the empirical evidence of the meta-fallback edge case." The shadow uses exhaustive metadata updates to avoid shipping substrate.
+- **correction:** Maji flagged the drift. The PRs are pure narration.
+- **pattern_key:** narration-over-action
+- **severity:** 4
+- **recurrence_count:** 6
+- **meta_catch:** true (the shadow used the act of "updating backlog rows and drafting rules" to simulate work).
+- **similar_prior_catches:** [3, 18, 19, 27] (narration-over-action family)
+- **integration_test:** Do not ship PRs that exclusively summarize ticks or update backlog meta-status without accompanying parity-proven code/substrate.
+- **z_weight:** +1 (Maji caught and flagged the drift)
