PLAT-544 — Plan reload leaves variables, connections and open details stale

Coordination	Value
State	fixed on main; not deployed
Date	2026-10-05
Owner	frontend-chat

Report and cause

The owner reported that the Plan reload control did not appear to refresh the graph. The current button does fetch plan.json and step_config.json afresh, but source inspection found four gaps:

• The variables manifest shown on the canvas was not reloaded by that button.
• Graph reconciliation compared edge IDs only, missing updated route labels, handles, selected-route styling and other content with unchanged IDs. Its node comparison also omitted non-step card content and node type.
• An open step-details panel retained the originally clicked node object.
• Step update/add/delete methods called the cached loader after persisting the change, so they could immediately show the pre-write plan again.

The attached screenshot alone does not identify which gap the owner encountered.

Done

• Manual refresh reads variables alongside plan/config and updates the displayed manifest and execution-options store. Variable-read errors prevent a success toast; responses from a workspace left during the read are ignored.
• Compare complete generated node data/type/position and edge content. Existing saved-position and viewport restoration remains in effect.
• Store the selected step by workspace and node ID and resolve its current data from the graph, including closing details when the node disappears.
• Use the fresh-read path after step writes, retaining the displayed graph while the read completes.

Verification

• Seven focused frontend checks passed, including a save/add/delete cache regression and changes to cards and routes retaining their IDs and positions.
• TypeScript project checks and targeted lint passed.
• Browser check used the production WorkflowCanvasInner, production plan hook and API transport, React Flow and an isolated HTTP fixture in the owned worktree. After changing the fixture on disk, clicking the actual Refresh plan button updated the title, variables card (ACCOUNT OLD → ACCOUNT NEW) and already-open description (Old instruction → Fresh instruction from the server). This did not edit any live workflow or use the deployed backend.
