+### Fixed (TypeScript & Linting)
+- **Strict Actions Type-Safety:** Refactoring type-safe catch blocks in all server actions to remove any explicit `any` types. Checked for `instanceof Error` dynamically when returning or logging errors.
+- **Prisma Actions Typing:** Strongly typed `updateData` variables using `Prisma.BannerHomepageUpdateInput` and `Prisma.KegiatanUpdateInput` instead of `any`.
+- **ZodError Bugfix:** Fixed a TypeScript check error in `potensi.action.ts` where `error.errors` was used instead of the correct `error.issues` for `ZodError` properties.
+- **Linter Warnings Cleanup:** Removed unused variable `searchParam` in `search.action.ts` to clear linter warnings.

 ### Changed (DevOps & Workflow)
 - **Branch Rename (pr -> dev):** Mengubah nama cabang integrasi/staging dari `pr` menjadi `dev` di seluruh berkas konfigurasi workflow GitHub Actions (`ci.yml`, `docs-sync.yml`), template PR (`PULL_REQUEST_TEMPLATE.md`), berkas kontribusi (`CONTRIBUTING.md`), blueprint arsitektur (`architecture.md`), serta berkas panduan AI (`.cursorrules`, `.agentrules`, dll.) demi memperjelas alur branching dan menghindari kebingungan.
