···8899## What it does
10101111-ladder takes a JSON request on stdin (or from a file argument), exports the requested assets from the Photos library to a staging directory, computes a SHA-256 hash for each file during export, and writes a JSON response to stdout. It is designed to be called as a subprocess by [attic](../attic), the Deno/TypeScript component of the photo-cloud backup system.
