ponystack

The contract gate (Seam 2). Closes a wide pass by cutting it to the minimum that works: reinvented stdlib, speculative abstractions, dead flexibility, one-caller layers. One line per finding, ends with the only number that matters. Use after a thorough plan or implementation, or when the user says "contract this", "cut it down", "what can we delete", "expand-contract", or invokes /ponystack-contract.

Thinking-to-diff ratio (Seam 3): reasoning spent divided by net code shipped. The membrane's scoreboard - a high ratio means the thinking went into the plan, not the line count. Use when the user says "ratio", "thinking-to-diff", "score this session", or invokes /ponystack-ratio.

The membrane between an expensive brain and cheap hands. Boil the lake to understand a problem; do not pour it into your code. Think expensive, write cheap. A phase router mutes the lazy senior while you plan and unleashes it while you implement. Use whenever the user says "ponystack", "membrane", "think expensive write cheap", complains that a process bloats the code, or wants gstack's thoroughness without gstack's line count.
