CaroFernando opened a new issue, #9075:
URL: https://github.com/apache/texera/issues/9075
### Feature Summary
The agent applies every workflow edit (`addOperator`, `modifyOperator`,
`deleteOperator`) as soon as it makes it: the change is saved and shown on the
canvas mid-run. Users can only react after several edits have stacked up, and
there is no way to undo a run as a unit or tell the agent what to fix
(requested in #8682).
This adds an optional **review mode**: the agent runs as today, and when a
run ends with the workflow changed, the user reviews the change and chooses
**Accept all**, **Reject all**, or **Request changes**.
Design discussion: #8931
### Proposed Solution or Design
| Aspect | Decision |
|---|---|
| Setting | Per agent: `editApprovalMode: "auto" \| "review"`, default
`auto` (today's behavior) |
| Granularity | One review per run, all or nothing (edits depend on each
other) |
| Request changes | A normal chat message sent while a review is pending;
the review always compares to the last accepted workflow |
| While pending | Canvas editing is locked; stopped or failed runs that left
edits are reviewable too |
| Reject | Restores and saves the workflow from before the review |
| Canvas | Added / modified / removed operators and links are highlighted;
"Show original" previews the pre-edit workflow read-only |
```
agent run ──► edits applied ──► run ends ──► [review pending]
│ │ │
Accept all ◄──┘ │ └──► Request
changes ──► agent run (same baseline)
(keep) ▼
Reject all (restore + save
baseline)
```
Planned PRs (each keeps CI green; the first two change nothing visible until
the UI lands):
| PR | Scope |
|---|---|
| 1 | agent-service: setting, review baseline, accept / reject |
| 2 | agent-service: WebSocket events and commands for reviews |
| 3 | frontend: "Review edits" toggle, review card, canvas lock |
| 4 | frontend: readable diff, canvas highlights, "Show original" |

turns), #5267 (agent state persistence).
