Review recently modified code for simplification opportunities in /Users/USER/workspace/doctolib/treatment-plan on branch fhir-2233-fix-toast-event-name.

Changed files: 1. packages/tpf-national-health-records-ui/src/business/toast.ts 2. packages/tpf-national-health-records-ui/src/business/toast.test.ts 3. packages/tpf-nhr-fr/src/components/dmp-consultation-consent-view/toast.ts 4. packages/tpf-nhr-fr/src/components/dmp-consultation-consent-view/toast.test.ts 5. packages/tpf-prescription-fulfillments/src/business/eprescription/toast.ts 6. packages/tpf-prescription-fulfillments/src/business/eprescription/toast.test.ts

Focus: Can the tests be simplified? Is there unnecessary duplication in the test files across the three packages? Is the implementation code clean?

fix(fhir-2233): align toast pub/sub event name with monolith toaster

TPF packages dispatched 'toasts:add' via GLOBAL_PUBSUB_REGISTRY, but the
monolith's <Toaster> component subscribes to 'toaster:add'. This mismatch
silently discarded every toast dispatched from module-federated TPF modules,
so DMP API error notifications never appeared.

# Plan: Simplify toast.ts / toast.test.ts across three TPF packages

Branch: `fhir-2233-fix-toast-event-name`. The fix commit changed the pub/sub event name from `'toasts:add'` to `'toaster:add'` in three near-identical `toast.ts` helpers and added a unit test for each. The user asks: can the tests be simplified, is there duplication across the three test files, and is the implementation clean.

## Summary of findings

Here is my analysis of the changed code. Plan saved to /Users/USER/.claude/plans/you-are-a-senior-replicated-elephant-agent-a87753db7c10337a4.md.

Headline answers

Can the tests be simplified? Yes, in three ways.

Is there unnecessary duplication across packages? Yes — but the right fix is a separate PR, not this one.

Is the implementation code clean? Mostly yes. Three minor inconsistencies between the three near-identical files are worth aligning while you're already in the area.

Tests — three concrete simplifications

1. Drop the dynamic await import('@doctolib/upfront-core') in every it body. vi.mock is hoisted, so a plain top-level static import { GLOBAL_PUBSUB_REGISTRY } from '@doctolib/upfront-core' already returns the mock. Pull it out once at module top, do const dispatch = vi.mocked(GLOBAL_PUBSUB_REGISTRY.dispatch), then each it becomes synchronous and one line shorter. Removes the async wart and gives you typed mock helpers.

2. afterEach(vi.clearAllMocks) — pass the function reference instead of wrapping it in an arrow.

3. Delete the second it in tpf-national-health-records-ui/src/business/toast.test.ts ('dispatches toaster:add event with optional action prop'). addToast is a pure pass-through with zero branching on action, so the second test re-asserts the same behavior the first one already pins. It's a tautology that tests the type system, not behavior — the project rule "test behavior, not implementation" applies.

Cross-package duplication — defer it

The three toast.test.ts files are byte-near-identical. Same mock factory, same afterEach, same assertion. Same for the three toast.ts helpers. The natural consolidation is to extract addToast and ToastProps into @doctolib/tpf-commons/business (the package exists, both consumers depend on it, the slot is open) and delete the three local copies.

I would not do that on this branch:

• The PR is a one-line event-name bug fix. Extracting a shared module enlarges blast radius (different CODEOWNERS, module-federation boundary) and changes the review story from "single-line fix" to "API consolidation."
• Three call sites of 13 lines each is below the threshold where one shared abstraction pays for itself, especially when the abstraction is a one-line wrapper around GLOBAL_PUBSUB_REGISTRY.dispatch.
• The original commit deliberately fixed all three independently for that reason.

File a follow-up ticket. Right scope is a separate refactor PR.

Implementation — three small inconsistencies between the three files

None of these are bugs and none change behavior; they're tidiness.

Recommended action set for this PR

1. tpf-prescription-fulfillments/.../toast.ts — convert arrow to function keyword, add : void.
2. tpf-nhr-fr/.../toast.ts — switch React.ReactNode to imported ReactNode, add : void.
3. tpf-national-health-records-ui/.../toast.ts — add : void.
4. All three toast.test.ts — replace dynamic import with static top-level import + vi.mocked(...), drop async, simplify afterEach.
5. tpf-national-health-records-ui/.../toast.test.ts — delete the redundant "with optional action prop" test.
