  1. assert imported function calls before switch statements resolve to imported bindings during SSR execution
  2. assert imported function calls in switch discriminant expressions resolve to imported bindings during SSR execution
  3. assert unbraced switch-case local declarations do not shadow imported bindings across the enclosing function in SSR transforms
  4. assert imported function calls after switch statements resolve to imported bindings during SSR execution

# Notes: Vite 8.1.5 SSR Switch-Case Declaration Scoping Bugfix

## `search_known_solution` Discovery
- **Initial CSX Search**: Called `search_known_solution` with `pkg:npm/vite`.
- **Existing Sample Found**: `sha256:3d6913c88e87048b4b55cebf64b6e0bd0e5c2fa4e748e8f754ff20cd2baf86bd` ("CommonJS dependencies require both ssr.noExternal and ssr.optimizeDeps to load named ESM imports under Vite SSR; externalizing fails with SyntaxError while noExternal alone silently produces undefined exports.").
- **Targeted Release & Fix**: As required when finding existing network matches, targeted a different, recent patch release: `vite@8.1.5` fixing SSR switch-case AST scope analysis.

## Release & Changelog Reference
- **Release**: `vite@8.1.5` (Released 2026-07-16)
- **Changelog Entry**: `packages/vite/CHANGELOG.md` under `8.1.5 (2026-07-16)`:
  - `* **ssr:** scope switch-case declarations to the switch, not the function (#22893) (b59a73f76f5557492d83d097bb33b3dd02f27d51)`

## Behaviour Before (`vite@8.1.4` and prior)
- During Vite's SSR transformation (`ssrTransform`), lexical declarations (`let`, `const`, `function`, `class`) inside an unbraced `case` clause of a `switch` statement were erroneously registered into the enclosing function's scope table rather than scoped to the switch statement.
- When an imported binding shared the same identifier name as a switch-case declaration, the AST visitor treated all occurrences of that identifier across the entire enclosing function (before the switch, in the switch test/discriminant expression, or after the switch) as references to the local variable.
- Consequently, Vite omitted the necessary SSR transform rewrite to `(0, __vite_ssr_import_0__.<name>)`.

## Behaviour Now (`vite@8.1.5`)
- Switch-case declarations are properly scoped to the switch statement block.
- Identifiers referencing the imported binding outside the switch statement (and inside the switch discriminant expression) are correctly rewritten to the SSR module import getter.
- Inside the switch case, the local variable correctly shadows the imported name for that case branch.

## How the Broken Version Fails
- The broken version (`vite@8.1.4`) fails **loudly** at runtime with:
  ```
  ReferenceError: formatValue is not defined
      at Module.runWorkflow (fixtures/ssr-switch-case.js:10:19)
  ```
  when `mod.runWorkflow()` is executed following `server.ssrLoadModule()`.
