End-to-end coverage of the new opt-in question via runAgentSdkTest.
Stubs the MCP endpoint at /tools/list with a 200 response carrying a
fake gbrain v0.32.3.0 serverInfo, and fakes the gbrain + claude CLIs
so init writes a PGLite config and mcp add succeeds. Asserts the model:
1. invokes gstack-gbrain-install (Step 4.5 Yes branch)
2. invokes `gbrain init --pglite --json`
3. writes a working ~/.gbrain/config.json with engine=pglite
4. registers the remote MCP via `claude mcp add --transport http`
5. never leaks the bearer token to CLAUDE.md
Classified as periodic-tier per plan D6 (codex #12 flagged AgentSDK
flakiness; gate-tier coverage of the split-engine behavior lives in the
deterministic unit tests at gbrain-local-status.test.ts and
gbrain-sync-skip.test.ts). Touchfile fires the test when the skill
template, install/verify/init helpers, the local-status classifier, or
the agent-sdk-runner harness changes.
