-Built with Andy Zhang for an employer. Tool to automate web scraping script
-generation.
+Work project. Browser session-to-code conversion.

-Manual script authoring took hours. Scripts poorly optimized, CPUs maxed
-constantly, cloud costs excessive.
+Architecture: C# WinForms host, embedded browser, code editor. Browser
+extension rejected due to security policy and shallow event control.
 
-Initially considered browser extension. Desktop app won—extensions don't give
-deep event control. Company policy blocked extensions anyway.
+Tool evaluation:
 
-First prototype: C# Win Forms + CefSharp. 
+ - CefSharp: Discarded. API lacked elegance.
+ - WebView2: Selected. Better WinForms integration. Hard dependency on
+   Microsoft Edge--acceptable for corporate Windows environments.
 
-Second prototype: C# Win Forms + WebView2. Packaging and distribution more
-complex, but the API is well-designed; integrates well with Win Forms. 
+Implementation:
 
-Microsoft Edge required. Portability not a concern, only need to target
-controlled Windows environments. Choosing WebView2 over CefSharp.
+ 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"

-Embed <a href="https://github.com/desjarlais/Scintilla.NET" class="external"
-toarget="_blank" rel="noopener noreferrer">Scintilla.NET</a> editor for
-overriding generated script.
+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.
 
-Code generation sequence: Inject JavaScript to intercept client-side events.
-Capture internal browser events (pop-ups, file downloads). Event
-raised → parsed into a token → insert to list → interpret event → look up
-instruction from a table → form instruction with event args → insert text to a
-parallel list → run both lists through optimizer → update Scintilla editor.
-
-Limitation: manual overriding via Scintilla editor mid-session causes the code
-list to go out of sync with the event list. Optimizer can't handle this yet.
-
-Note to self: need to rethink the event/text list data structures in the
-context of the optimizer--look to compilers for inspiration maybe?
+Verdict: Serves its purpose.
