instructionChain (spec 3.0.0, filesystem.md): from the boundary — the project
root — down to the start directory, outermost first, each directory gives the
first of AGENTS.md, CLAUDE.md that is a file really inside the project; one
that is not (a link out) is passed over and the walk goes on below it. Before,
only the nearest file counted. The chain's files are named to the model by
their path in the project; agentsBlock reads them all: none means "make one",
and git is settled when any of them settles it.
Conformance runner for the `instructions` area (all 9 cases pass).
