## lib

Call lib through its module, never through its headers.
test(agents): what a consumer's AGENTS.md gets, and what stays put The merge on its own: the section is appended after one blank line, merging again changes nothing, a moved section is rewritten where it stands, and removing it gives the file its own bytes back. Markers inside a fenced block, one quoting a fenced block of its own, are not the section's. Unbalanced markers, a document that ends inside a code block and notes that would break the section are refused, naming the line. End to end, through LoadProject on a staged fixture: app names lib and has tool as host tooling; lib builds against base and has libtool as its own. Transitive gives tool, lib and base in that order, and neither app's own notes nor libtool's. A second update writes nothing, mtime included. Direct drops base, edited notes replace the old ones in the one section, and None restores the original bytes. A project without an AGENTS.md does not get one, and a symlinked AGENTS.md is written through the link, which stays a link. Through Run in process, lint and run leave the file alone, while `test --list` and a build that fails at the link both refresh it. The fixture's AGENTS.md is checked in as AGENTS.md.in: an AGENTS.md in this tree would read as instructions for the agents working on it. Moving the CLI hook above the run and lint branches, or letting Direct walk past the first loaded project, fails four of the checks.
