The .texlabroot caveat is discharged, and discharging it falsified the
reasoning behind it.
.texlabroot is real, and texlab marker set is wider than this document
listed --- the bare texlabroot and latexmkrc spellings count too, and
the walk takes the innermost. The implementation ships texlab own set.
But the caveat framed marker 1 as conditional on texlab honouring the
FILE, which was the wrong question. Every arm of texlab ancestor walk
searches documents already loaded, and that workspace is built from the
folders the CLIENT supplies. Observed: with rootUri at chapters/, no
ancestor marker widened texlab view and its dependency graph never
reached the parent document; with rootUri at the marker directory the
parent resolved either way.
So texlab honours the root it is handed and never corrects a too-narrow
one. config.latex.root IS the project scope, which makes the resolver
the whole value of the lane for a multi-file thesis rather than a
nicety --- the opposite of how section 2 "Slice 1 is one config entry"
reads.
Second correction, and this one was a real trap. Revision 2 said .git
is deliberately excluded from the walk and stopped there. Omitting it
is not sufficient: project_root_for falls through to
pmacs.project.detect when a resolver returns nil, and that walk lists
.git among its markers at src/project.rs:184. A resolver that politely
declined on a markerless file would hand texlab the monorepo by the
back door, with the exclusion looking correct at every line you would
think to read. The resolver never declines for a file with a directory,
and the fixture asserts the shared detector really would have answered
the repo root so the pin cannot pass vacuously.
