+Label each `<pass>.<label>`: the local part is 64 bytes in all, so the pass is at
+most about 24 bytes and the label at most about 38. The first note is labelled
+`scope`: your method and what you did not search. Every note has a source (a repo
+pin, a web page, something you observed, or another document); `inferred: true`
+names a claim you read from its sources rather than saw in them. A note is a fact,
+never a recommendation. A batch is 1 to 64 documents; a larger pass spans batches
+under one pass label. A wrong or superseded note is not edited: admit the new one
+and leave the old to a steward. You resolve nothing. Raw output too long for a note
+stays under `<scratchpad>/<agent>/` and the note cites it as an Observed capture.
+If Private is yes, admit nothing and write to the file named. Report the pass label
+and counts, not the findings again.
