bin/gstack-install-verdict.sh (Bash) and lib/install-verdict.ts (TypeScript)
are the one reader of the install verdict gstack-capy-install writes to
<state root>/install-verdicts/<sha256(checkout realpath)>.json (checkout,
HEAD, workflow and required components, planning-only pins, trailer). The
source checkout and capy/support.env resolve through gstack_source_root /
sourceRoot, which follow an installed root's .source-path.
gstack-skill-start, after SESSION_KIND: an unattended session (any host)
refuses on a PATH Bun below the supported minimum; with GSTACK_CAPY=1 an
unattended or explicit spawned session also refuses without a passing
verdict for this checkout, HEAD and workflow (INSTALL_UNVERIFIED). A refusal
prints the INSTALL: row, an install-refused instruction block bound to its
SESSION_ID, GSTACK_RESULT ... status=refused run=- and exits 3. Ambient
spawned sessions warn; GSTACK_ALLOW_UNSUPPORTED_RUNTIME=1 admits and says so.
capy/support.env declares GSTACK_MIN_REVISION and GSTACK_CAPY_MIN_WRAPPER.
