A relocation between two interior scopes journals a parking leg and an arriving leg. The command journaled them in two enqueue_op calls and took the parking leg back on a best-effort basis when the arriving leg failed, which cannot undo a leg a tick already drained. The StagingStore seam gains enqueue_ops, one atomic write for several entries in the enqueue_op entry format, implemented in the testkit fake, the desktop file journal (a batch marker is the commit point, and open rolls back an uncommitted set), the browser IndexedDB store (one transaction) and the wasm bridge. The conformance kit gains a batched phase.
The overlay stamped the renamed or relinked node, which the drain never republishes, and did not stamp the parent folders the drain republishes at authored_at. Op::authored_nodes now returns the stamped set per op kind, as ADR 0045 D5 decides: a create stamps the new node and its parent, a rename and a delete the parent, a relink and a move both parents, and updateContent the node alone. The overlay stamps that set, and the drain's publish plans take each folder's modified_at from the same function, so the published records do not change. The drain also paints a created node's time into the base, so the view does not lose it at publish.

Roll back the op file of a failed batch write too, since its write can land before the directory barrier fails. Test the restore and content stamps, stamp a parent in the metadata stamp test, drop the unused fallback of stamped_modified_at, and edit ADR 0045 in place now that the code meets D5 and D6.
List the ops directory once at open, carry a batch as one id range, and name the counter error after the shared id reservation. Let authored_nodes read the parents only for a kind that stamps them, so the overlay scans no links for a create or a content op. Key the stamp test helpers by set and map, and correct ADR 0045 Consequence 8 now that the code does the work.
…batch whose commit barrier fails The overlay stamped every parent that links a renamed or moved node, but the drain republishes only the winning parent, so a dual-linked node's other folder jumped back at publish. authored_nodes now reads the parents winner first and keeps the winner for a rename, relink or move, and every parent for a delete. The drain's stamped_modified_at check could not fail, so the drain writes authored_at directly again. The desktop store writes the batch marker again and rolls the set back when the marker's unlink barrier fails.
The create, delete, restore and ref-move plans take the folders that get the op's authored time from Op::authored_nodes, with the same winner-first parents as the overlay, and keep a folder's own time otherwise.
…oval roll_back_batch now tries to remove every op file of the set and keeps the first error, and removes the marker only when all of them went. The ref-move plan passes its winning source parent to authored_nodes, and the stamp tests assert the exact winning parent.

- Around line 152-171: Update write_batch and roll_back_batch so a durable
recovery marker remains available until every batch operation file has been
removed; do not ignore rollback failures in a way that can leave files visible
after reopening. Serialize rollback with queued_ops using the store’s shared
operation lock so readers cannot observe a partially rolled-back batch.

Once the marker unlink lands, the live directory shows the whole set, and a crash before the directory barrier can only bring the marker back, which open rolls back whole. So a failed barrier after the unlink no longer rolls the set back and reports a failure for a set that is queued. A failed unlink still rolls the set back and returns the error.

Summary
Two fixes for the residuals E2 and E3 of ADR 0045.
Both legs of a staged move journal in one atomic write (ADR 0045 D6). A relocation between two interior scopes journals a parking leg and an arriving leg. Before this change, the command journaled them in two
enqueue_opcalls. When the arriving leg failed, the command removed the parking leg on a best-effort basis. That removal cannot undo a leg that a tick already drained.StagingStoreseam gainsenqueue_ops. It queues several entries in one atomic write, or none of them. Each entry has theenqueue_opentry format, so a reader of the queue cannot tell the two apart.ops/<first>-<last>.batch, then the op files. The removal of the marker is the commit point. While the marker stands,queued_opsdoes not show the entries of the set. A failed write removes the files that it wrote.openrolls back a set that a crash interrupted.addthat throws aborts the transaction, so the earlier adds do not commit.enqueueOps. It rejects an answer that does not have one id per entry.stage_legs_and_notifyseals both legs, then journals them withenqueue_ops. The best-effortdequeue_opcleanup is gone.batchedphase: order, ids, verbatim payloads, durability across reopen, and removal of one entry of a set.The overlay and the drain stamp the same nodes (ADR 0045 D5).
Op::authored_nodesreturns the stamped set per op kind. A create stamps the new node and its parent. A rename and a delete stamp the parent. A relink and a move stamp both parents.updateContentstamps the node alone. A restore stamps the folder that it restores into, which is the folder that the drain republishes atauthored_at. Prune, purge, restoreVersion and deleteVersion stamp nothing, as before.modified_atof each republished folder from the same function. The published records do not change, because the set holds every folder that these plans republish.The
