Hand over the result and the reasons behind it.

Someone else needs to review your analysis. Bellfly keeps the goal, changes, checks and repairs connected so the next person can understand the work.

The final file cannot explain every decision.

A reviewer asks why a source was chosen or a figure changed. You search old messages and terminal output to reconstruct the answer.

The original brief, source materials, changes and existing work record for the result being handed over.

Once the goal and limits are clear, each next step does not have to wait for you.

Bellfly keeps the source materials connected to the task they informed.
As agents work, it records meaningful changes, checks and questions without asking you to keep a separate diary.
Repairs stay connected to the problems they addressed and the checks that followed.
While you move on to other work, Bellfly gathers a readable summary alongside the output.

A result may contain a conclusion whose source or check cannot be found.

Bellfly identifies the gap and arranges a new check where possible. A later check is recorded as new work, without rewriting what was known earlier.

The output, a work summary, source references, checks, repairs and open questions in a connected record.

You decide what to share. The receiver decides whether the record is sufficient for their review; readable history is not legal certification.
