pi-hifi

Read this BEFORE using the `hifi` tool on a hard or large engineering task (non-trivial code, a tricky algorithm, a system design, an incident diagnosis). hifi verifies ONE self-contained artifact by running it; this explains how to extract the verifiable pieces of your work and delegate each as one hifi run, instead of one-shotting a hard piece yourself or handing hifi a whole feature, scaffold, or multi-file build.
