/**
 * Git-backed remediation identity.
 *
 * FeltDB does not trust an agent's claim that it changed the code. It captures
 * observable repository state before handing an investigation to the agent and
 * again afterwards, and treats the difference as evidence that remediation
 * occurred.
 *
 * A commit is not required. An agent that edits the working tree without
 * committing has still changed the repository, so the working-tree digest is a
 * first-class change identity.
 *
 * Detecting a repository change proves that remediation happened. It does not
 * prove the defect is fixed — only a runtime observation can do that.
