 the pending copy, while a revision conflict preserves both the phone plan and fresh server snapshot for
 review. Unsynced Tomorrow work is never promoted into Today.
+**Plan Week Ahead** continues through seven local dates and now finishes on a mobile review step instead of
+closing after the seventh save. The review shows planned minutes against each day’s capacity, marks overloads,
+and flags work assigned to more than one date. Operators can move an item to another date without copying it;
+the estimate follows the item and the server rejects duplicate cross-day assignments without advancing the
+week revision. Confirmation remains disabled while duplicates exist or the account-bound week is still syncing.
+Rapid saves and review moves use one network flight plus a coalesced latest-state delivery, so later staged days
+are not stranded behind an earlier request.
 Planning edits can remain offline for up to 30 days. After that, the
 expired edit is discarded visibly and the account plan is kept rather than replaying stale
 intent. The server retains no more than 4,096 operation receipts per account and removes
