# =============================================================================
# ci-mesh-lifecycle-smoke.sh — relay-driven mesh lifecycle smoke
# =============================================================================
# Provisions a membership-gated buzz-relay and runs the full relay-driven
# mesh lifecycle harness (crates/buzz-mesh-smoke/examples/mesh_relay_lifecycle_smoke.rs):
# membership → signed discovery notes → relay-derived allowlist → join →
# inference over QUIC → stranger denied.
#
# Mirrors the shape of mesh-llm's own CI smoke scripts (single runner, tiny
# CPU model, real multi-process mesh), but with the Buzz relay as the control
# plane instead of a hand-carried invite token.
#
# Usage:
#   ./scripts/ci-mesh-lifecycle-smoke.sh [--profile <cargo-profile>] [--no-build]
#
# Env:
#   MESH_SMOKE_MODEL   Override the served model ref (default: SmolLM2-135M).
