Project description:
"I have a JavaScript file that has been run through an aggressive obfuscation process and I need it converted back into clean, human-readable code. I’m not sure which exact technique was applied—minification, string encoding, control-flow flattening, or a mix of them—so I’m looking for someone comfortable analysing whatever protection was used and reversing it safely.

You will receive the original .js file as-is. Your task is to produce an equivalent script that:

• runs identically in any modern browser or Node.js environment
• is fully formatted and clearly named (variables, functions, classes)
• contains brief inline comments where the original logic was hard to follow
• is delivered together with a short summary explaining what you changed, which tools or custom scripts you employed (e.g. Babel, Acorn, Esprima, de4js, custom AST walkers), and any suspicious or malicious behaviour you found

Please keep the structure self-contained so I can diff it against future versions of the obfuscated build. If the job sounds straightforward to you, let me know how long you expect to need once you see the file and which tooling you plan to rely on." (client-provided description)
