fix(core): run a batch's operations on a block before the one that removes it - #2227
The batch contract: a batch equals its operations applied one at a time, with every operation that addresses a block before any operation that deletes or merges that block away. A single edit can only address a block that still stands; direct mode refuses one aimed at a block already removed.
Before this change, the shared batch order could run a merge or deletion first. Tracked changes then kept the block addressable, so direct and tracked batches disagreed. Example: [setBlockParagraphProperties b1 center, mergeBlockWithNext b0] in tracked changes, accepted, kept center on the joined paragraph. The same batch applied directly, and the valid one-at-a-time order, carry b0's properties over it.
Reported flow (styleNumbered, tracked): one batch inserts a table after a paragraph already pending deletion, deletes the final paragraph 1BF99289, and inserts a table after 1BF99289. The scenario replay deleted 1BF99289 before inserting after it, a sequence direct mode refuses. Run first, the final-paragraph deletion retired the heading's break onto the emptied paragraph and left an empty Heading2 paragraph the batch, rightly, does not.
Changes:
@stll/docx-core/ops: orderAddressingBeforeRemoval moves each operation that addresses a block ahead of the earliest operation removing it and keeps every other operation where orderBatchOperations put it. deletionRemovesBlock says which deletions take a block out: a container's last paragraph with no kept paragraph before it only empties, and stays addressable.
@stll/folio-core: the engine orders every batch through both. mergeBlockWithNext removes the paragraph after its anchor; deleteBlock removes its block unless it only empties it (a block the batch puts after the last paragraph makes it no longer last).
The tracked carry no longer keeps properties a batch set on the paragraph it carries onto (propertiesSetInBatch and its plumbing are gone). Under the new order those writes run before the carry, so the carry overwrites them, as applied directly.
test/consumer-scenarios/support/batch-replay-order.ts: the one-at-a-time replay uses the shared order instead of its own copy.
Every batch operation now reads its positions in the document as it stands when it runs (its positions mapped through the steps already taken), and finds whether its block still stands by mapping it from the document the batch read. Running from the end backwards is no longer what keeps positions valid, so the shared order can run an edit before one further left. Deleting a table row or a table counts as removing its anchor block.
A property edit of a paragraph that a merge in the same batch joins away is no longer refused when applied directly. It runs before the merge in either mode, and the merge gives the merged paragraph the first one's properties in both. The batch-claims rule and the direct-mode check of blocks an earlier operation removed both drop that refusal; no tracked-mode refusal is added.
A property edit of a paragraph that the batch deletes, when it isn't its container's last paragraph, now also runs first instead of being refused. For a story's last paragraph, direct and tracked mode refuse different operations of the batch but leave the same document. The class test pins which operation each mode refuses there.
Changed expectations (each encoded the old order, where a deletion ran before an operation on the block it deletes):
batch-order.test.ts, the split-deletion permutation test: the table insertion now replays before the deletion of its anchor, and the test also checks that the one-at-a-time replay equals the batch.
batchRemovedBlock.test.ts, "refuses an edit of the block an earlier direct merge removes": now "applies a format of the block a direct merge removes before the merge". Both apply; the merge keeps the first paragraph's text and properties.
flow-replay-atomicity.test.ts, seed 877798201: was "refuses insertion on a deleted anchor and rolls back only atomic batches". The insertion before an anchor the same batch deletes now applies, atomic or not. The next test in the file still covers an atomic batch with a conflict.
pendingTrackedBlockEdits.test.ts, "refuses an insertion after its inserted anchor is retracted before a table": now "applies an insertion before an inserted anchor the same batch retracts, as one at a time". The insertion runs first, so it lands and the retraction then removes only the anchor.
pendingTrackedBlockEdits.test.ts, "degrades a move deletion when its refused insertion loses the anchor": now "applies a move destination before the source the same batch removes, unpaired". Both operations apply; the move is still reported unpaired.
pendingTrackedBlockEdits.test.ts, the suggested gap-run sweep: the "same batch" cases moved to "deleteBlock/deleteTableRow and insertBeforeBlock/insertAfterBlock in one batch apply as one at a time, the insertion first". The insertion and the deletion both apply. The earlier-batch and saved cases are unchanged.
batchRemovedBlock.test.ts, "a batch that removes a block and then formats it": now "formats the block before removing it and leaves the next paragraph alone". The format runs before the removal, so both apply and nothing is skipped.
batchOverlap.test.ts, the tracked refusal for setBlockParagraphProperties, deleteBlock, insertAfterBlock on a story's last paragraph: now deleteBlock instead of insertAfterBlock. The earlier pin left a different document in tracked mode than in direct mode, which the same test requires to match; direct and tracked now refuse the same operation in all six orderings.
The consumer scenario oracle accepts one more case: a paragraph property edit replayed after a deleteBlock of the same block, only when that block was last in its story or table cell before the batch and the result still holds it, emptied and last (the last-paragraph rule keeps it), as in batch-removed-block-after-table-edit.json. It then checks the requested paragraph properties on the kept block; any other edit after a removal is still reported. requested-outcome.test.ts covers the kept case, a missing property and a block that is really removed.
New tests:
batchOrder.test.ts: the shared order and the deletion rule.
batchOverlap.test.ts: every permutation of {set properties on bN, merge bN−1 into bN or delete bN, insert after bN}, for every N: the batch equals its operations one at a time in both modes, and tracked-and-accepted equals direct.
batch-order.test.ts: a block addressed and then deleted, or merged away, in one batch replays the address first in either input order.
Pins the reported flow in tracked changes and in direct mode.
Batch edits that target a block now run before operations that delete or merge it, including paragraph formatting and insertions anchored to that block.
Tracked-change results now match the outcome of applying the same batch directly.
Bug Fixes
Improved handling of paragraph formatting and paragraph breaks when deletions or merges affect the final paragraph.
…ves it
The one-at-a-time replay that batchSequential compares a batch with could delete or merge a block away before an operation the batch aimed at it, which no single edit can state: direct mode refuses the operation, and tracked changes only accept it because the deleted paragraph stays addressable. A batch that inserts a table after the final paragraph it deletes then read against a replay where the deletion ran first and left an emptied heading the batch rightly does not. The replay now runs every run that addresses a block before the run that deletes or merges it away, and keeps the existing order otherwise. A container's final paragraph that its deletion only empties still stands and keeps its place.

…moves it
Direct and tracked batches disagreed when a batch addressed a block it also deleted or merged away. The shared batch order ran the merge or deletion first; tracked changes then kept the block addressable and kept properties the batch set on it over the ones the merge carried, while the same batch applied directly lost them. The shared order in @stll/docx-core/ops now runs every operation that addresses a block before the operation that removes it, with deletionRemovesBlock deciding which deletions take a block out (a container's last paragraph with no kept paragraph before it only empties). The engine and the scenario replay both use it, and the carry no longer keeps properties a batch set on the paragraph it overwrites.

fix(core): run a batch's operations on a block before the one that removes it
Oct 30, 2026
The shared batch order runs an operation that addresses a block before the one that removes it, which can run an edit before another further left. Operations read their positions in the document the batch read and relied on running from the end backwards, so an insertion run early moved the text a later deletion cut. Each operation now maps its positions through the steps already taken when it runs, and finds whether its block still stands by mapping it from the document the batch read. A property edit of a paragraph that a merge in the same batch joins away is no longer refused when applied directly: it runs before the merge in either mode, and the merge gives the merged paragraph the first one's properties in both.
…ssing before removal
Deleting a table row or a table takes the anchor block with it: the shared order now counts those operations as removals rather than as edits of their anchor, so an edit of a block in the row runs before the row goes. A property edit of a paragraph a merge in the same batch joins away is no longer refused when applied directly, whichever the batch names first. Suggested insertions beside a block the same batch deletes now run before the deletion, as one at a time, and apply.

Cache each operation's block access during ordering.
orderAddressingBeforeRemoval calls accessOf for every operation on each round. For each operation that addresses a block, it also calls accessOf on every earlier operation. In blockAccess, the deleteBlock branch scans executableResolved on each call. A batch with many deleteBlock operations and many block-addressing operations therefore does cubic-scale work. This happens without any reordering, because the first pass still visits every operation. An operation's access depends only on that operation and on batch state that does not change during ordering. One lookup per operation therefore produces the same order.
Suggested fix
export const orderAddressingBeforeRemoval = <T, Block>(
ordered: readonly T[],
accessOf: (operation: T) => BatchBlockAccess<Block>,
): T[] => {
const result = [...ordered];
+ const accesses = new Map<T, BatchBlockAccess<Block>>();+ const cachedAccessOf = (operation: T): BatchBlockAccess<Block> => {+ const cached = accesses.get(operation);+ if (cached !== undefined) return cached;+ const access = accessOf(operation);+ accesses.set(operation, access);+ return access;+ };
const removesAny = (remover: T, blocks: readonly Block[]) => {
- const { removes } = accessOf(remover);+ const { removes } = cachedAccessOf(remover);
return blocks.some((block) => removes.includes(block));
};
// Every move takes an operation earlier, past at least one remover, so the
// order settles; the bound only guards against a cycle.
for (let round = 0; round <= result.length * result.length; round += 1) {
const from = result.findIndex((operation, at) => {
- const { addresses } = accessOf(operation);+ const { addresses } = cachedAccessOf(operation);
return (
addresses.length > 0 &&
result.slice(0, at).some((earlier) => removesAny(earlier, addresses))
);
});
if (from < 0) return result;
const operation = result[from];
if (operation === undefined) return result;
- const { addresses } = accessOf(operation);+ const { addresses } = cachedAccessOf(operation);
const to = result.findIndex((candidate) =>
removesAny(candidate, addresses),
);
result.splice(from, 1);
result.splice(to, 0, operation);

Pin the final insertTable on 1BF99289 in both collision flows.
Each collision flow runs its core batch with "atomic": false. A refused operation drops out of the applied list without an error. No assertion in the runner requires the final insertTable on 1BF99289 to apply, so a refusal of that operation still passes. The batch applies the deleteBlock and the first insertTable, so the vacuity check does not flag it.
coreBatch assigns IDs by list position (op-1, op-2, op-3). The final insertTable is therefore op-3. Add an optional requiredApplied array of operation IDs to core batch steps:
In parseStep, accept requiredApplied only for core batch and story batch steps. Require a non-empty array of strings.
In coreBatchStep, throw when a listed ID is missing from outcome.applied.
Set "requiredApplied": ["op-3"] on the collision step in issue-1356-table-after-a-deleted-final-paragraph.json and issue-1356-table-after-a-deleted-final-paragraph-direct.json.
Leave the other operations unlisted, so the stale anchors stay optional. Keep all three operations in one batch.
When rebindStepOperations changes the operation list, drop requiredApplied or recompute it. Its IDs depend on the list order.

It builds replay groups with sequentialGroups, applies each group to a sequential reviewer, and asserts replay order and that no operation is skipped. It never applies the full [address, remove] list in one applyDocumentOperations call and never compares document views. A regression in the batch applier for these two cases would not fail this test.

…stands
The check for a pending property change mapped a position the operation had already read through the batch's steps a second time, so an insertion run before it moved the target off its paragraph and the edit wrote over a pending change. The direct-mode test of a format on a paragraph a merge joins away now expects both to apply, the format first.
… before deleting
Each operation keeps the block content the batch read: a later replacement of a paragraph no longer takes in the separator an earlier merge of the batch appended. A table after a deleted split anchor uses the retracted-split placement only once the anchor is gone. A property edit of a paragraph the batch deletes runs before the deletion instead of being refused, except for a container's last paragraph, whose refusals stay as they were. The class test asserts the same document directly and tracked for every permutation, every operation applied away from the last paragraph, and pins which operation each mode refuses there.
…its anchor stands
A block beside a pending join looked for its anchor by mapping the anchor's start through every step of the batch, though the position it holds already accounts for the steps taken before it ran. The anchor is now mapped through the steps since it was read, as every other operation of the batch maps its positions.
…ced in its gap
Operations at one gap run in reverse of the order the batch names them, so each block insertion has to land ahead of the blocks inserted there before it. An insertion before a block landed after them instead: a paragraph and a table inserted before the same block came out with the table first, and a comparison that added a paragraph and then a table after the last block refused its own result. Every block insertion now keeps the left side of its gap.
… retires the break before it
Tracked, deleting a container's last paragraph retires the break of the paragraph before it, and accepting runs that paragraph into this one with its own properties, as applied directly this one goes. A format of the deleted paragraph contradicts that, and was refused applied directly but applied tracked: in a batch that also inserted a block after the paragraph, tracked then refused the insertion while direct refused the deletion, and the two left different documents. Tracked now refuses the same operation as direct whenever the deletion retires a break: the nearest paragraph before it the batch keeps has its break, and no merge of the batch deletes that break first. A last paragraph with nothing to retire still takes a format.
…a deletion keeps
A format of a paragraph the batch deletes runs before the deletion and goes with the paragraph, so the batch applies both: the test that expected the format refused now expects both applied and the next paragraph unchanged. The scenario oracle replays the batch in the shared order, where a format follows a deletion only when the deletion keeps the paragraph, emptied, at its container's end; it no longer reports that format as an edit of a removed block, and compares nothing of the blank paragraph, as for any other.
… a removed block
The scenario oracle now replays a paragraph property edit after the deletion of its block only when that block was the last of its story or table cell before the batch, and the result still holds it, emptied and last. Any other such edit is reported as an edit of a removed block, as before. The kept block must carry the requested paragraph properties: the oracle reads them from the result's emptied block, which the text comparison leaves out.

The batch contract: a batch equals its operations applied one at a time, with every operation that addresses a block before any operation that deletes or merges that block away. A single edit can only address a block that still stands; direct mode refuses one aimed at a block already removed.
Before this change, the shared batch order could run a merge or deletion first. Tracked changes then kept the block addressable, so direct and tracked batches disagreed. Example:
[setBlockParagraphProperties b1 center, mergeBlockWithNext b0]in tracked changes, accepted, keptcenteron the joined paragraph. The same batch applied directly, and the valid one-at-a-time order, carry b0's properties over it.Reported flow (
styleNumbered, tracked): one batch inserts a table after a paragraph already pending deletion, deletes the final paragraph1BF99289, and inserts a table after1BF99289. The scenario replay deleted1BF99289before inserting after it, a sequence direct mode refuses. Run first, the final-paragraph deletion retired the heading's break onto the emptied paragraph and left an emptyHeading2paragraph the batch, rightly, does not.Changes:
@stll/docx-core/ops:orderAddressingBeforeRemovalmoves each operation that addresses a block ahead of the earliest operation removing it and keeps every other operation whereorderBatchOperationsput it.deletionRemovesBlocksays which deletions take a block out: a container's last paragraph with no kept paragraph before it only empties, and stays addressable.@stll/folio-core: the engine orders every batch through both.mergeBlockWithNextremoves the paragraph after its anchor;deleteBlockremoves its block unless it only empties it (a block the batch puts after the last paragraph makes it no longer last).propertiesSetInBatchand its plumbing are gone). Under the new order those writes run before the carry, so the carry overwrites them, as applied directly.test/consumer-scenarios/support/batch-replay-order.ts: the one-at-a-time replay uses the shared order instead of its own copy.Every batch operation now reads its positions in the document as it stands when it runs (its positions mapped through the steps already taken), and finds whether its block still stands by mapping it from the document the batch read. Running from the end backwards is no longer what keeps positions valid, so the shared order can run an edit before one further left. Deleting a table row or a table counts as removing its anchor block.
A property edit of a paragraph that a merge in the same batch joins away is no longer refused when applied directly. It runs before the merge in either mode, and the merge gives the merged paragraph the first one's properties in both. The batch-claims rule and the direct-mode check of blocks an earlier operation removed both drop that refusal; no tracked-mode refusal is added.
A property edit of a paragraph that the batch deletes, when it isn't its container's last paragraph, now also runs first instead of being refused. For a story's last paragraph, direct and tracked mode refuse different operations of the batch but leave the same document. The class test pins which operation each mode refuses there.
Changed expectations (each encoded the old order, where a deletion ran before an operation on the block it deletes):
batch-order.test.ts, the split-deletion permutation test: the table insertion now replays before the deletion of its anchor, and the test also checks that the one-at-a-time replay equals the batch.batchRemovedBlock.test.ts, "refuses an edit of the block an earlier direct merge removes": now "applies a format of the block a direct merge removes before the merge". Both apply; the merge keeps the first paragraph's text and properties.flow-replay-atomicity.test.ts, seed 877798201: was "refuses insertion on a deleted anchor and rolls back only atomic batches". The insertion before an anchor the same batch deletes now applies, atomic or not. The next test in the file still covers an atomic batch with a conflict.pendingTrackedBlockEdits.test.ts, "refuses an insertion after its inserted anchor is retracted before a table": now "applies an insertion before an inserted anchor the same batch retracts, as one at a time". The insertion runs first, so it lands and the retraction then removes only the anchor.pendingTrackedBlockEdits.test.ts, "degrades a move deletion when its refused insertion loses the anchor": now "applies a move destination before the source the same batch removes, unpaired". Both operations apply; the move is still reported unpaired.pendingTrackedBlockEdits.test.ts, the suggested gap-run sweep: the "same batch" cases moved to "deleteBlock/deleteTableRowandinsertBeforeBlock/insertAfterBlockin one batch apply as one at a time, the insertion first". The insertion and the deletion both apply. The earlier-batch and saved cases are unchanged.batchRemovedBlock.test.ts, "a batch that removes a block and then formats it": now "formats the block before removing it and leaves the next paragraph alone". The format runs before the removal, so both apply and nothing is skipped.batchOverlap.test.ts, the tracked refusal forsetBlockParagraphProperties, deleteBlock, insertAfterBlockon a story's last paragraph: nowdeleteBlockinstead ofinsertAfterBlock. The earlier pin left a different document in tracked mode than in direct mode, which the same test requires to match; direct and tracked now refuse the same operation in all six orderings.The consumer scenario oracle accepts one more case: a paragraph property edit replayed after a
deleteBlockof the same block, only when that block was last in its story or table cell before the batch and the result still holds it, emptied and last (the last-paragraph rule keeps it), as inbatch-removed-block-after-table-edit.json. It then checks the requested paragraph properties on the kept block; any other edit after a removal is still reported.requested-outcome.test.tscovers the kept case, a missing property and a block that is really removed.New tests:
batchOrder.test.ts: the shared order and the deletion rule.batchOverlap.test.ts: every permutation of {set properties on bN, merge bN−1 into bN or delete bN, insert after bN}, for every N: the batch equals its operations one at a time in both modes, and tracked-and-accepted equals direct.batch-order.test.ts: a block addressed and then deleted, or merged away, in one batch replays the address first in either input order.Refs #1356
