OpenCode's gateway turns away requests that do not name their conversation
in x-opencode-session ('Request is missing x-opencode-session and cannot be
routed efficiently'), and magpie never sent it. Requests to opencode.ai now
carry the agent's own session id (OpenCode's x-session-affinity, Pi's,
Codex's session_id, Claude Code's) or, when the agent sends none, an id
derived from the conversation's first user message, stable across turns;
the provider test sends one too. OpenCode's docs ask exactly this of
third-party clients, along with their own User-Agent, which magpie already
sends.
