* Tasks: modern io.modelcontextprotocol/tasks extension (era fork core) Core + test-server implementation of the SEP-2663 tasks extension for modern (2026-07-28) connections, forked from the legacy 2025-11-25 tasks path. SDK v2 removed all tasks support AND era-gates the tasks/* spec methods out of the modern era on both the client (outbound) and server (inbound) sides, and its codec rejects a resultType:"task" result outright. So the Inspector drives the extension itself: task creation rides tools/call (a modern method) with the resultType:"task" frame rewritten at the transport to a CallToolResult carrying the handle in _meta; tasks/get/update/cancel go over a raw-wire request channel that bypasses the era gate (full modern envelope, string ids, consumed by the transport). input_required tasks reuse the existing pending-request modal via fulfilInputRequests, answered with tasks/update. No tasks/list, no tasks/result. Tab + run-as-task gate on the negotiated extension; the managed task store's refresh re-polls known handles on modern (no server list). Test server serves the extension via an Express interceptor (SDK can't) + a shared poll-driven runtime. Full integration coverage of both eras.

Fixes the App and constructor-capabilities tests for the always-on tasks extension.

Share one modern + one legacy test server across the era integration block (started lazily, stopped in afterAll) — starting a fresh Express server per test made connection negotiation flaky under the heavy concurrent coverage run.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XNdjEPKLG637X8YmhDiEk5 * Tasks modern era: offer Run-as-task for any tool + PR screenshots On modern (SEP-2663) task creation is server-directed — the client declares the extension once and any tool may return a task — so the Tools screen now offers 'Run as task' for every tool on a modern connection (threaded via a modernTasks prop through InspectorView → ToolsScreen → ToolDetailPanel), rather than gating on the legacy per-tool taskSupport. Verified end-to-end in the web UI (remote proxy): create → poll tasks/get → input_required elicitation → tasks/update → inline result, plus the unchanged legacy tasks/list/result flow. Adds proof screenshots.

The pending-request note now distinguishes a modern task round from an MRTR round: a new 'task-input-required' PendingRequestOrigin threads through fulfilInputRequests → the pending-request modal → MrtrOriginNote, which shows 'submitted via a tasks/update request (SEP-2663), not a retry' instead of the MRTR retry copy. 2. The ordinary (non-run-as-task) modern callTool path now auto-polls an unsolicited task handle: attemptToolCall detects the rewritten handle in the result _meta and drives it to termination (get → input_required/update → inline result), dispatching task events so the Tasks tab + toasts track it and the tool result resolves to the task's final result. The poll loop is shared with the streaming path via extracted helpers (submitModernTaskInput / modernTaskTerminalOutcome / modernTaskPollInterval).

MODERN_PROTOCOL_VERSION) so the envelope matches the MCP-Protocol-Version header instead of a hardcoded constant. 2. A never-completing input_required task is now bounded by MRTR_MAX_ROUNDS in the shared submitModernTaskInput (threaded through both poll loops), so a non-conformant server can't re-prompt the user forever. New modern_loop_task test-server tool + integration test cover the cap. 3. ToolDetailPanel: comment clarifying that per-tool taskSupport:"forbidden" is deliberately ignored on modern (task creation is server-directed under SEP-2663). (The abort-during-poll observation is addressed in the PR reply: the cancel path uses tasks/cancel and disconnect rejects the in-flight raw request, so the poll stops; matches legacy.) Fresh web-UI smoke screenshots (modern connected, task completed, input_required with the corrected tasks/update note, input completed). Refs #1631 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XNdjEPKLG637X8YmhDiEk5 * Tasks modern era: fix uncancelable input-required loop + sticky cancel Two bug fixes reported during manual testing of the tasks era-fork (#1631): 1. A modern task paused at `input_required` (e.g. `modern_loop_task`, which never advances) could not be cancelled: the poll loop blocked on the pending-request modal, so `cancelRequestorTask` sent `tasks/cancel` but the modal kept re-prompting. Now each modern poll loop registers a per-task AbortController (`registerTaskInputAbort`), `cancelRequestorTask` aborts it to reject the pending elicitation and unblock the poll, and the embedded input requests are tagged with their owning task id (`RELATED_TASK_META_KEY`) so the pending-request UI's Cancel action cancels the TASK rather than sending a "cancel" answer the server would re-prompt on. 2. On the legacy server, cancelling a task briefly showed CANCELLED then flipped to COMPLETED when the in-flight tool call resolved. Cancellation is a deliberate terminal decision, so `ManagedRequestorTasksState` now remembers cancelled task ids and ignores any later non-cancelled status update. Also: move the compact task id onto its own line in the embedded monitoring sidebar so the status badge / Cancel Task control don't wrap; DRY the duplicated task poll-interval logic into a shared `taskPollInterval` helper.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XNdjEPKLG637X8YmhDiEk5 * Address re-review: sticky cancel on legacy refresh + App cancel-routing test Re-review of the cancelable-loop / sticky-cancel fix raised two non-blocking hardening items: 1. The legacy tasks/list refresh() rebuilt the list from the server, honoring only dismissedTaskIds — so a cooperative-cancel server that re-lists a user-cancelled task as completed could un-stick the cancel on a manual Refresh. The refresh path now pins a cancelledTaskIds task to "cancelled" (keeping it visible-as-cancelled, matching the live-merge handlers) rather than dropping it. Covered by a new state test. 2. Added an App.test.tsx case locking in the user-facing half of the fix: Cancel on a task-input-required elicitation calls cancelRequestorTask (not respond).
