Folio
Making long-form
research recoverable.
The problem
Long reports cannot rely on one uninterrupted generation. A failed section should not require regenerating every completed chapter.
The approach
Plan chapters, execute concurrently, persist checkpoints and retry failed sections. Each chapter becomes a smaller execution boundary that can be inspected and resumed.
Request → Plan → Context / Tools → Validate / Persist.
Boundary
Keep chapter work separate so failures can be isolated and completed sections retained.
Recovery
Retry failed sections rather than restarting the entire report. Resume from the last durable checkpoint.
State
Persist task progress and chapter outputs so recovery does not depend on a single process remaining alive.
