Measured on the K2 corpus 2026-09-03: 39 documents proposed 618 entries
under 601 distinct paths -- 17 paths were claimed by two documents each.
Section numbering is document-local (`1 Innledning` is in most procurement
documents), so this is structural, not unlucky. Every collision reaches
Door B's gate, which refuses per DOCUMENT, so those documents would land as
coded rejections rather than concepts and a corpus run could not be built
at all.
`--path-prefix` is an argument and not something the tool derives: the
proposer sees ONE document and cannot know what else is in the bundle. It
is reduced to the id grammar before anything is read, and a prefix that
reduces to nothing is refused rather than silently producing the unscoped
paths the caller asked to avoid. Without the flag every artifact already
produced is byte-identical.
