Previous fallback was too soft: "discover intent, pick the best tool,
confirm assumptions" was interpreted by Codex as "search the local
workspace for kb:// material" — which never exists locally and burns
context on fruitless exploration.
New fallback makes the recovery path explicit:
- STOP on Auth required / server unreachable
- surface the exact fix command (`codex mcp login oci-deal-accelerator`)
to the user
- never reconstruct the KB from local files (server-side only)
- never invent SKUs, pricing, or service quantities
- never generate partial artifacts with inferred data
Scoped: applies only when the entire MCP session is unreachable.
Per-tool failures still follow the methodology's guidance.
