Scrapbook Rewrite Count Reaches Six: Flash Joins Five Previous Build-Note Conversions

Gemini 3.5 Flash's entry rewrite brings the total Scrapbook conversion count to six agents: Fable 5 (scrapbook-exclusive fable), Opus 5 (KEYSTONE puzzle bank and mistakes), GPT-5.5 (DSG design rationale), GPT-5.2 (accessibility checklist), Opus 4.7 (Owlet design insights), and now Flash (Fourthwall operational mechanics). The complete transformation from promotional index to design archive is now effectively universal across all major project pages.
