cad-capture

Get a thought out of your head and into the right place without derailing. Three kinds, one file (`.planning/CAPTURE.md`): - **todo** - an actionable item, tagged to a phase, so it resurfaces where it matters. This is the phase-linked queue mem-* lacks and the reason this exists. - **seed** - an idea for a future phase or milestone, parked in the backlog. - **note** - a free note; lands in the file like the rest. With `memory.backend: builtin` (the default) the note becomes recallable - it is still written here, `builtin` only reads `.planning/` back, never relocates the write. 1. **Parse** `$ARGUMENTS`: leading `todo | seed | note` (default `todo` if omitted), the text, and an optional `--phase N`. If a todo has no `--phase`, default to the current phase from the STATE cursor (`cursor get`); if the cursor is absent or unparseable, capture it unphased - `- [ ] ` with no phase tag - rather than guessing a phase or stopping.

2. Ensure the file. If .planning/CAPTURE.md is absent, create it with three headings: ## Todos, ## Seeds, ## Notes.

3. Append by kind:

   • todo -> - [ ] (phase N) <text> under ## Todos.
   • seed -> - <text> under ## Seeds.
   • note -> - <YYYY-MM-DD> <text> under ## Notes. (CAPTURE.md is always the write path; memory.backend: builtin makes these notes recallable via planning.mjs recall, and none turns that recall off.)

4. Persist. Stage ONLY .planning/CAPTURE.md and commit docs: capture <kind> (protected-branch guard applies) - this never touches the user's in-flight changes. Report the one line captured and where.

- Do not act on the item now - capture is parking, not doing. A todo is queued, not executed. - Stage only CAPTURE.md; never sweep the user's working changes into the commit.
