 ## Hard rules
 
+- Don’t assume. Don’t hide confusion. Surface tradeoffs.
+- Minimum code that solves the problem. Nothing speculative.
+- Touch only what you must. Clean up only your own mess.
+- Define success criteria. Loop until verified.
 - Do not use `Math.random()` anywhere in game logic.
 - Do not skip `nextTickAt` jitter — synchronised global ticks will thunder-herd Postgres.
 - Do not assume Twitch PubSub message delivery; treat as a hint to refresh, reconcile from REST.
 - Do not add inline scripts or inline event handlers to the overlay HTML — Twitch CSP forbids them.
-- Do not reproduce Dead by Daylight assets, character names, or trademarked terms in encounter content. The aesthetic is *inspired by* the genre, not a clone.
