The calendar spine isn't an archive — it's a timeline that keeps summarizing itself.
The calendar spine isn't an archive — it's a timeline that keeps summarizing itself.
The calendar spine (day to week to month to quarter to year) is not a filing cabinet where dated things go to rest; it's alive. New inputs land on it — captures, transactions, even imported AI chat history — and cascade roll-ups continuously re-summarize each level, so 'what happened this quarter' and 'the themes of this year' are always current. Anything you route onto the spine by date automatically joins the story and shows up in the summaries. A graveyard stores; a Living Timeline compounds meaning over time.
Where it lives: Cascade roll-ups + calendar-as-spine; the payoff of routing everything by date.
