/**
 * Local recovery for things the vault cannot restore.
 *
 * `.git` is ignored on purpose (size, machine-local, credentials in config),
 * so a vault pull after a wiped HQ tree brings files back and loses history.
 * Empty `repos/public` and `repos/private` are also never uploaded (S3 has no
 * empty directories).
 *
 * The sidecar lives under the machine HQ state dir (`~/.hq/hq-root-git/…`),
 * which survived the 2026-09-18 wipe that removed `core/`, `personal/`, and
 * `.git` while leaving the sync daemon running.
