The generator lane's C1 resolves D from $GSTACK_ROOT instead of
$GSTACK_DESIGN, so the test now exports GSTACK_ROOT as well; it still fails
on main (no dist in the roots) and passes with and without the C1 change.
Codex skips a symlinked SKILL.md file, so the gstack router linked into
~/.codex/skills/gstack was invisible. Every host runtime root (Codex,
Factory, OpenCode, Cursor, Copilot, Kiro) and Kiro's per-skill installs
now get real copies, rewritten on every run (the auto-update path runs
setup --refresh-registered, so it refreshes them too). setup records each
copy's hash in <state root>/skill-copies.tsv; a copy that no longer matches
is saved to a uniquely named backup under <state root>/backups/skill-copies/
before _activate_runtime_root replaces the tree, and a failed backup keeps
the old tree. setup prints what it refreshed or removed.
./setup --status now prints, per registered install, whether the router is a
real file and whether every section pointer resolves, with the fix command.
Test migration: setup-codex-model pinned the Kiro router/upgrade links as
_link_or_copy; C3 deliberately changes them to copies.
Codex design and make-pdf skills fall back to $GSTACK_DESIGN and
$GSTACK_MAKE_PDF under the runtime root, but setup linked only browse/dist,
so both preflights reported NOT_AVAILABLE on a fresh install. One helper
links dist/ only (make-pdf/ ships a Claude SKILL.md) into the Codex,
Factory, OpenCode, Cursor, Copilot and Kiro roots, the .agents sidecar and
the Cursor sidecar.
