+### Iteration 4 — Zero-Plausible Interpretations Checkpoint (2026-10-02)
+
+Implementation commit: `0cc9d08` — "permit empty plausibleInterpretations for honest zero state"
+
+The fixed zero-plausible regression case established:
+- Canonical representation: `plausibleInterpretations = ""`, `hasPlausibleInterpretations = false`;
+- Deterministic verification: 71/71 PASS;
+- One live Update report call on investigation `eae84f2d` returned canonical zero state, moved report to CURRENT;
+- Report rendered correctly: "What remains plausible" omitted, "What we understand" and "What remains unresolved" intact, obsolete absence prose absent;
+- Update report ownership: Report page + only when stale (production behaviour).
+
+Evidence is specific to this one fixed live regression case. Does not generalise universally.
