// The archive reader, as this server has always known it.
//
// This file WAS the reader: 1,386 lines holding the only good walk of the
// published shard scheme in the repo, plus three transports and two caches. It
// now lives in `yt-dlp-transcript-common/lib/archive/`, where the viewer, the
// offline cache and umtool can reach the same implementation instead of each
// re-deriving the walk (one-core plan, phase 2). Nothing about it changed in
// the move — the interface is the same 18 members under a new name, and there
// is deliberately still no per-record fetch.
//
// `ShardSource` stays as the name every importer here already spells, so this
// server's seven `./source` importers and `mcp/bench` (which spawns the server
// and never imports this file) are untouched.
