Command docsummary splices the SUMMARY.md fragment a `pulse docs export` writes into the book's own SUMMARY.md, between the docgen.BookSpanBegin / BookSpanEnd lines, prefixing every path with the export directory.

Command pkgsplit is the in-module AST rewriter used to split a public package in place: the kept subset stays in the public directory, the remainder moves to an internal twin that imports the public package.

Command refcohorts converts the R oracle's vendored fixture CSVs into the `.pulse` cohorts service tests read.
