Repair

A repair brings the tool back to doing what it already should. A bug is a piece like any other. /shape reproduces it and writes the failing case into the piece, by references/reproduce.md, and /implement builds the repair by references/fixing.md. The discipline is the order: never change code before the problem repeats reliably and the cause is understood and explained.

Load the one the step needs:

• references/reproduce.md: the four checks before shaping, then reproducing and minimising the fault and writing the piece.
• references/fixing.md: building the repair, one cause at a time, the cleanup, and the escalation after three failed attempts, with the notice it owes.
