+### D-088: 3-state pause system — Normal/Overlay/Paused, server-authoritative
+- **Date:** 2026-02-12
+- **Decision:** Simulation runs at three speed states: Normal (100% tick rate), Overlay (50% — active during knowledge panel, dialogue, map view), Paused (0% — full pause via Esc). Server is authoritative: client sends pause requests, server sets `sim_speed` field in ObserverSnapshot. Client reads `sim_speed` and adjusts presentation. No client-side tick manipulation.
+- **Rationale:** Server-authoritative speed states preserve D-010 principle 4 (deterministic simulation). Client cannot modify simulation state directly. Overlay mode at 50% ensures UI interactions do not require a hard pause while still giving the player time to read and decide.
