Use a note for a thought. Use a planning card for a future story element you can already name. Use a manuscript section when it is ready to become text.
Note: “I do not know what this is yet”
A sentence, question, visual association, research fragment, possible scene, or contradiction can stay a note. It does not need to pretend to be structural.
Planning card: “I know what role this should play”
A future scene, beat, event, or planning element may have a purpose before it has prose. A planning card gives it identity and relationships without forcing you to draft it immediately.
Chapter or section: “this now belongs to the manuscript”
Once the idea has a real place in the reader's sequence and is ready to carry text, it should become part of the manuscript structure.

If every thought becomes a chapter, the manuscript fills with placeholders. If everything stays a note, planning never becomes executable structure. Different containers let uncertainty disappear gradually instead of all at once.
You can promote an idea later
The point is not to classify perfectly on first capture. Start lightweight. Move the idea into a stronger form only when the project has earned that decision.
