# migrate-v0220.sh — ONE-TIME claude-spt update-channel migration (ADR-0008 relocation).
# Patches the INSTALLED adapter's [update].repo to the private home, then pulls v0.22.0+
# through the normal `spt adapter update` path. Run once per node; endpoints need no action
# (the new adapter rides each endpoint's next start). Distributed via the migration/v0.22.0
# branch and internal announcement — never via a committed pointer in the public repo.
# Usage:  gh api -H "Accept: application/vnd.github.raw" \
#           "/repos/BigscreenVR/claude-spt-bs/contents/migrate-v0220.sh?ref=migration/v0.22.0" | sh
# [impl->REQ-DIST-MIGRATION-SCRIPT]
