 * Example: no-amend rule pack.
 *
 * Equivalent to `steering.json` in this directory but expressed in the
 * v0.1.0 canonical TypeScript form. Drop this file in at
 * `.pi/steering.ts` (or `.pi/steering/index.ts`) to activate.
 *
 * What it enforces: blocks `git commit --amend` in any form. Useful
 * on review-driven workflows where commit-SHA stability matters (an
 * amend rewrites the SHA, which breaks reviewers' cross-push diff
 * tracking).
 *
 * Scope note: does NOT conflict with any shipped `DEFAULT_RULES`.
 * The rule is additive.
