-<p>Manual script authoring took hours. Scripts poorly optimized, CPUs maxed
-constantly, cloud costs excessive.</p>
+<p>Architecture: C# WinForms host, embedded browser, code editor. Browser
+extension rejected due to security policy and shallow event control.</p>
 
-<p>Initially considered browser extension. Desktop app won—extensions don’t give
-deep event control. Company policy blocked extensions anyway.</p>
+<p>Tool evaluation:</p>
 
-<p>First prototype: C# Win Forms + CefSharp.</p>
+<ul>
+  <li>CefSharp: Discarded. API lacked elegance.</li>
+  <li>WebView2: Selected. Better WinForms integration. Hard dependency on
+Microsoft Edge–acceptable for corporate Windows environments.</li>
+</ul>
 
-<p>Second prototype: C# Win Forms + WebView2. Packaging and distribution more
-complex, but the API is well-designed; integrates well with Win Forms.</p>
+<p>Implementation:</p>
 
-<p>Microsoft Edge required. Portability not a concern, only need to target
-controlled Windows environments. Choosing WebView2 over CefSharp.</p>
+<ol>
+  <li>Interception: Injected JS hooks; internal browser event monitoring
+(pop-ups/downloads).</li>
+  <li>Transformation: Event → Token → Instruction Table → String.</li>
+  <li>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></li>
+</ol>
 
-<p>Embed <a href="https://github.com/desjarlais/Scintilla.NET" class="external" toarget="_blank" rel="noopener noreferrer">Scintilla.NET</a> editor for
-overriding generated script.</p>
+<p>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.</p>
 
-<p>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.</p>
-
-<p>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.</p>
-
-<p>Note to self: need to rethink the event/text list data structures in the
-context of the optimizer–look to compilers for inspiration maybe?</p>
+<p>Verdict: Serves its purpose.</p>
