 ## v0.2
 
 - [ ] **Inline template support** — Allow passing SQL strings directly without requiring a `.sql` file, reducing boilerplate for short one-off queries
-- [ ] **Template caching** — Cache loaded templates in a `Map` to avoid redundant `readFileSync` calls when `defineQuery` is used outside module scope
+- [ ] **Export rendered SQL to file** — Add an option to write the rendered SQL to a file for debugging and audit purposes
 - [ ] **TypeDescriptor `description` field** — Add an optional `description` property to `TypeDescriptor` so schema validation errors can display the expected format (e.g. `Expected: ISO date YYYY-MM-DD`)
 
 ## Maybe
 
+- [ ] **Template caching** — Cache loaded templates in a `Map` to avoid redundant `readFileSync` calls when `defineQuery` is used outside module scope
 - [ ] **Conditional blocks / IN-list expansion** — Support optional WHERE clauses (`{{#if}}`) and array expansion (`WHERE id IN ({{ids}})`). Would change the library's templating nature significantly — evaluate only if `.sql` file duplication becomes a real pain point
 - [ ] **Async `loadTemplate`** — Non-blocking file reads for server environments (Express, Fastify). Not needed for current Lambda/script use cases
 - [ ] **Query execution integration** — Return parameterized output or integrate with Athena SDK. Intentionally out of scope to preserve single responsibility — better suited as a separate package
