The installer pinned gbrain at v0.18.2 while gbrain shipped v0.41.x — ~23 versions
behind. Remove the hard pin: a fresh clone now stays on the latest default-branch
HEAD. --pinned-commit <sha> still pins for reproducibility.
Unpinning removes the version gate the pin provided, so add two install-time gates
that fail closed (exit 3, matching the existing PATH-shadow/version-mismatch posture):
- MIN_GBRAIN_VERSION floor (0.20.0, the sources-list/federated surface gstack needs):
refuse an install below it.
- gbrain doctor --fast self-test when a brain config already exists (re-install /
detected clone): refuse to leave a broken gbrain in place. Pre-init installs skip
it; the full /sync-gbrain --dry-run self-test runs from /setup-gbrain after init.
Docs updated (USING_GBRAIN_WITH_GSTACK.md no longer says 'edit PINNED_COMMIT').
Detect-install tests bump the success-path fixtures above the floor and add a
below-floor exit-3 test. The gbrain-side asks (root #1526 fix, --keep-storage,
remove-lease, capability command, ingest-resume, integration CI) are written to
.context/gbrain-asks.md for filing against garrytan/gbrain.
