# Migration: v1.37.0.0 — split-engine gbrain (remote MCP brain + optional
|
|
# local PGLite for code search per worktree).
|
|
#
|
|
# Per plan D5: prints a ONE-TIME discoverability notice for existing
|
|
# Path 4 users who don't yet have a local engine. They learn that
|
|
# symbol-aware code search (gbrain code-def / code-refs / code-callers)
|
|
# is now available via /setup-gbrain Step 4.5 if they want it.
|
|
#
|
|
# When to print the notice (state match — all conditions must hold):
|
|
# - ~/.claude.json declares mcpServers.gbrain.{type|transport} = http|sse|url
|
|
# OR mcpServers.gbrain.url is set (remote-http MCP active)
|
|
# - ~/.gbrain/config.json is absent (no local engine yet)
|
|
# - User has not previously opted out via:
|
|
# ~/.claude/skills/gstack/bin/gstack-config set local_code_index_offered true
|
|
#
|
|
# When silent: anything else (Path 1/2/3 users, anyone already on PGLite,
|
|
# anyone who opted out, anyone without remote-http MCP).
|
|
#
|
|
# Idempotency: writes a touchfile at ~/.gstack/.migrations/v1.37.0.0.done
|
|
# on completion. Re-running this script is silent if the touchfile exists,
|
|
# OR if local_code_index_offered=true.
