TODO.md's Next Step names the open issues, not a closed one (closes #194)

Next Step said the cache design, issue 36, waits on sneak's review. That
issue closed on 2026-10-03. Next Step now names what is open: the backup
concurrency issue, built in pull request 192 and waiting on review, and
the live-account check that only sneak can run.

 # Next Step
 
-None: no implementation work is open. The cache design,
+`quak backup` downloading one original at a time,
-https://git.eeqj.de/sneak/quak/issues/36, waits on sneak's review.
+https://git.eeqj.de/sneak/quak/issues/182, is fixed in
+https://git.eeqj.de/sneak/quak/pulls/192, which waits on review. No other
+implementation work is open. The check of quak against a live Ente account,
+https://git.eeqj.de/sneak/quak/issues/187, needs an account only sneak has, so
+it waits on him.
 
 Tagging and releases are decided by sneak alone, and happen only when he
 declares one.
 
 # Completed Steps
 
+- 2026-10-14: Next Step said the cache design, issue 36, waits on sneak's
+  review, though that issue closed on 2026-10-03 (issue 194). It now names the
+  issues open on the tracker.

 - 2026-10-14: A backup whose lock is lost no longer dies with a stack trace
   (issue 184). `lockBackupDirectory` gives proper-lockfile an `onCompromised`
   that records why the lock was lost instead of throwing from its timer, and
