+# Changelog
+
+All notable changes to this project will be documented in this file. The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/), and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [Unreleased]
+### Added
+- Shared pagination utility `applyPaginationDefaults` with configurable `MAX_PAGE_SIZE` (default **100**).
+- Unit tests covering pagination helper edge cases.
+- Integration tests validating enforced pagination across list endpoints.
+
+### Changed
+- List endpoints for Hotels, Customers, Rooms, and Reservations now automatically enforce a maximum page size of 100 records when the client omits or exceeds this limit. Negative `skip` values are clamped to `0`. (**Performance fix**, closes #84)

+## API Pagination & List Limits
+
+To ensure stable performance and prevent accidental full-table scans, the server enforces a **maximum page size of 100 records** on all list (findMany) endpoints. If a request omits the `take` query parameter—or specifies a value greater than 100—the response will be limited to 100 items.
+
+Guidelines:
+
+1. Always include an explicit `take` parameter when paginating large datasets.
+2. Values of `take` greater than `100` are automatically reduced to `100`.
+3. Negative `skip` values are coerced to `0`.
+
+The limit currently applies to the following resources: **hotels**, **customers**, **rooms**, and **reservations**.
+
+_Introduced in vNEXT – see [CHANGELOG](./CHANGELOG.md) for details._
