Work project. Browser session-to-code conversion.

Architecture: C# WinForms host, embedded browser, code editor. Browser
extension rejected due to security policy and shallow event control.

Tool evaluation:

 - CefSharp: Discarded. API lacked elegance.
 - WebView2: Selected. Better WinForms integration. Hard dependency on
   Microsoft Edge--acceptable for corporate Windows environments.

Implementation:

 1. Interception: Injected JS hooks; internal browser event monitoring
    (pop-ups/downloads). 
 2. Transformation: Event → Token → Instruction Table → String.
 3. Optimization: Parallel event/text lists processing; rendered
    in <a href="https://github.com/desjarlais/Scintilla.NET" class="external"
    target="_blank" rel="noopener noreferrer">Scintilla.NET</a> 

Bug: Manual mid-session overrides desync code/event lists, bypassing optimizer.
Linear lists inadequate for state synchronization. Need to rethink data
structures; look to compiler Abstract Syntax Trees (AST) for intermediate
representation.

Verdict: Serves its purpose.
