I need to confirm a suspected root cause: a pub/sub event name mismatch between the TPF package and the monolith's toast system.

Read these files fully:

1. /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/national-health-records/src/hooks/useSearchDocuments.ts - Read the full implementation

2. Search for the monolith's toaster package: - ls /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/ - Look for any package named "toaster" or "toast" - Read its src/business/toast.ts or equivalent

3. Search for where the Toaster component is mounted in the monolith: grep -r "Toaster|addToast|toast:add|toasts:add" /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/toaster/src/ --include=".ts" --include=".tsx" -l Then read those files.

4. Also search in the monolith app/ folder: grep -r "toast:add|toasts:add" /Users/USER/workspace/doctolib/doctolib/app/javascript/ --include=".ts" --include=".tsx" -l 2>/dev/null | head -10

5. Read /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-national-health-records-ui/src/business/toast.ts in full

KEY QUESTION: - What event name does the TPF toast.ts dispatch? (Expected: 'toasts:add') - What event name does the monolith's Toaster LISTEN TO? (Expected: 'toast:add' from Oxygen, OR 'toasts:add') - Are these the same or different?

Report the exact event type strings from both sides.

I'll help you confirm this pub/sub event name mismatch. Let me start by reading the files and searching for the event names.

Excellent. I have confirmed the root cause. Let me write a comprehensive report:

ROOT CAUSE CONFIRMED: Pub/Sub Event Name Mismatch

You have a critical pub/sub event name mismatch between the TPF packages and the monolith's Toaster component.

The Mismatch

They do NOT match. The TPF sends 'toasts:add' but the monolith listens for 'toaster:add'. Toasts will never reach the UI.

Evidence

TPF Side (Dispatchers):

1. /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-national-health-records-ui/src/business/toast.ts (line 12) ```typescript GLOBAL_PUBSUB_REGISTRY.dispatch({ type: 'toasts:add', payload: props })

2. `/Users/USER/workspace/doctolib/treatment-plan/packages/tpf-nhr-fr/src/components/dmp-consultation-consent-view/toast.ts` (line 17)
 ```typescript
 GLOBAL_PUBSUB_REGISTRY.dispatch({ type: 'toasts:add', payload: props })

3. /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-prescription-fulfillments/src/business/eprescription/toast.ts (line 11) ```typescript GLOBAL_PUBSUB_REGISTRY.dispatch({ type: 'toasts:add', payload: props })

**Monolith Side (Listener):**

1. `/Users/USER/workspace/doctolib/doctolib/packages/@doctolib/toaster/src/business/toast.ts` (line 4)
 ```typescript
 export const ADD_TOAST = 'toaster:add'

2. /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/toaster/src/components/Toaster/Toaster.tsx (lines 17, 19) ```typescript registerEvents: [ADD_TOAST], // ADD_TOAST = 'toaster:add' subscriptions: { [ADD_TOAST]: ({ payload }: { payload?: object }) => payload && queue.add(payload as ToastProps), },

```

Root Cause Analysis

The TPF packages appear to have been written with the assumption that the monolith's event name is 'toasts:add' (note the plural: "toasts"), but the actual monolith Toaster component constant is 'toaster:add' (singular: "toaster" with "add" suffix). This is a simple spelling/naming mismatch between two independent implementations.

Impact

Any toast notifications triggered by TPF packages (NHR search, prescriptions, consent dialogs, etc.) will be dispatched but never received by the monolith's Toaster component, resulting in silent failures from the user's perspective.
