CLAUDE WATERMARK REMOVER · DESTINATION TEST
Can I reverse a preview without changing the stored row list?
Yes. toReversed returns CD then AB and leaves the original list AB then CD.
What the test establishes
The callback preserves the line break between the two records. A reverse-order preview is then constructed independently from the stored order. That distinction matters when the export must keep source ordering while the review interface starts with the newest entry. The observation verifies both arrays after the call, rather than inferring immutability from the preview alone. No destination file is written during this test.
Reproduce the observation
Save tested-app.js and reproduce.cjs together, then run node reproduce.cjs. Compare its output with the recorded observation. The harness executes the actual homepage callback in a minimal DOM and records its resulting field values and method calls. Destination operations run in Node.js; the homepage DOM is a controlled substitute. Runtime: v24.22.1. No submitted text or genuine Claude output is used.

These are two primitive strings. The test does not validate chronological ordering or deep-copy object rows.
This Claude watermark remover edits a small selected character set. These callback observations do not establish authorship, detector scores, statistical-watermark removal or end-to-end browser behavior. For real work, keep the original and compare the exact result at its destination.
