From bc550e2b30a183baab43d63cda67800627c6f97c Mon Sep 17 00:00:00 2001 From: HeavenllyDemon <160774215+HeavenllyDemon@users.noreply.github.com> Date: Tue, 18 Aug 2026 04:25:31 +0100 Subject: [PATCH 1/5] feat(mcp): McpTaskRegistry + a task-capable test server MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Third sibling of bg-registry (bash) and bg-agent-registry (subagents), with the same lifecycle-only, never-throws, takeForNotification-exactly-once contract. First terminal state wins, so an abort racing the stream's own settlement cannot be rewritten by a straggling result. The test server is built on the SDK's own server half, so the task test story costs no new dependency. Getting it to actually produce a task took three attempts, and the fixture documents all three requirements because each fails differently — most dangerously the missing server capability, which makes the call run synchronously with no error at all.
