About

SUBDossier

SUBDossier is a small desk for keeping research on projects you’re looking at. One dossier per name, so you’re not hunting through random notes three weeks later. Inside a file you can park the boring-but-important bits: supply notes, team names, roadmap scraps, a couple of rivals, a rough score, and a short dated take on where you landed. If you need the receipt, snap a page or a dashboard and hang the photo on that dossier. There’s a simple side-by-side when two names feel too alike, and a flag list so open risks don’t vanish into chat history. Bench keeps the old calls and the “how I usually start” path when you’re stuck. The vault starts empty on purpose. Make a dossier when you’ve got something real, or open a blueprint if you just want a blank shell with prompts. Field guide and layout preview are there if you want to see how a file is structured before you fill one in. This isn’t a tip feed and it isn’t advice. It’s a place to keep your own homework straight.
