Suggested labels: Suggested reviewers: Merge Risk: 🔵 Low · up to An empty page value can make a navigation action run in multiple open tabs and return a result from the wrong tab. This is a narrow, recoverable developer-workflow risk; the change is otherwise mergeable, with a small validation or fallback recommended. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

In @packages/ng-devtools/src/overlay.ts:
- Line 302: Update the overlay’s `sentGeneration` logic so it advances only when
`push-router` confirms the config was stored; otherwise reset it so later
reports resend the config. Return that stored-config status from the server’s
`push-router` handler, reset `sentGeneration` on `pageshow`, and remove the
listener during teardown.
In @packages/ng-devtools/src/router.ts:
- Around line 782-783: Update noteFailedCall to assign each failed-call record a
unique, monotonically decreasing id using a module-level counter rather than
deriving it from navigations.length. Keep the existing list cap and other record
behavior unchanged.

- resend the route config when the server does not have it, and on pageshow - give failed navigation calls unique ids

- Around line 196-205: Update the `request-router-action` handler to use
`defaultPageId()` when `message.pageId` is absent or not a string, so the action
targets one page instead of broadcasting to all connected tabs. Move the
`defaultPageId` declaration before this registration so it is available to the
handler.

pagePropertyaccepts any string, including"". The??fallback preserves that value. The overlay then treats the empty value as an untargeted broadcast, so every router-bearing tab can execute the action. The first tab response resolves the request, which can return a result from a different tab.Suggested fix
- const result = await requestRouterAction(args.page ?? defaultPageId(), request); + const result = await requestRouterAction(args.page || defaultPageId(), request);🤖 Prompt for AI Agents
