Noggin

A working-memory tree for in-flight work — your second brain for the work you can't fit in your head. Items form a tree: any item can have child items. Push when you go on a side-quest so you don't lose your place; add a child when you want to remember a todo without diving in; goto an item to make it active; mark it done when it's finished; use edit for explicit lifecycle correction. An item just has a title, a done flag, and append-only notes — no fixed schema for what content matters. Backed by a single YAML file via a small CLI; the file is the source of truth. USE FOR: I'm pausing this to chase X, side-quest, defer this, jot down a todo under what I'm doing, where was I, push an item, add a todo, goto an item, move up with `goto ..`, mark this done, edit, what was I working on, what's on my noggin, drop a resumption note before I context-switch. DO NOT USE FOR: long-term plans (use the engineer/plan workflow), team-visible task tracking (use ADO/work items), persistent project memory (use repo memory or docs).
