# RFC-029 PR① — smoke gate.
#
# What this locks:
#   S1: normalize-runtime unit tests all pass (21/21 including 5 new).
#   S2: wizard help / usage strings surface `opencode-cli` as a choice.
#   S3: `anet node start X` on a node whose runtime is `opencode-cli`
#       hard-fails with a clear "install opencode-ai@1.18.1" message
#       when opencode is NOT on PATH.
#   S4: with `opencode-ai@1.18.1` installed, `anet node start` passes
#       the version pin, spawns agent-node, and agent-node's PR①
#       processTask stub returns a clear "not yet implemented" line
#       (proving the runtime registration reaches all four seams:
#       agent-network CLI → agent-node cli.ts RUNTIME_MAP →
#       processTask switch → server normalizeRuntime).
#   S5: a non-empty unknown runtime in config fails closed before any
#       launcher/dependency fallback can silently run Claude instead.
#
# Non-mock. Real bun. Real opencode install/uninstall on a real PATH.
# No vendor key required (the stub trips before any vendor call).
