// batch11-nested-rkey.mjs — the drive check for c035f50.
//
// DeleteManifestHandler used to hand-build the tag rkey as "repo:tag" while the
// write path uses RepositoryTagToRKey ("repo_tag", with "/" encoded as "~").
// For a nested repository like stream/cache the two never match, so the delete
// removed the local cache row while leaving the io.atcr.tag record on the PDS —
// and the tag reappeared on the next backfill.
//
// A flat repo name cannot reproduce this: the bug lives entirely in the "/"→"~"
// encoding. The assertion is therefore against the PDS record, not the page:
// the UI looks correct either way until a backfill runs.
//
// Needs the signed-in profile (lib.mjs PROFILE) because the delete endpoint is
// session-authenticated. Drive it via ctx.request so the cookie jar and UA come
// from the browser — see README, a mismatched UA deletes the session.
