Upgrade impact: none (additive). No lint codes added/removed and no behavior change to existing skills — a lint advisory's guidance changed, and RemoteMcpConnector now honors the cancellation signal it previously ignored.

Sharpens how you bound external work, after a real autonomous gather (perry-brief-gather) hung ~2 min on a slow remote leg. The levers were already there — this makes the framework point at the right one.

• The unbounded-no-deadline advisory was steering authors to the wrong lever. It nudged toward # Deadline: — a whole-run, uncatchable cap that aborts every leg including healthy ones — even for a partial-tolerant gather, and even when a leg was already bounded. Reframed: a $ leg carrying its own timeout=N (catchable, per-leg) or a skill with # Timeout: no longer trips it, and the message/remediation now lead with per-op timeout=N + (fallback:) as the everyday bound, framing # Deadline: as the separate hard-total-ceiling tool. help({topic: "frontmatter"}) / lint-codes reworked to the two-levers distinction.
• timeout=N works on any $ connector op — it always has (the runtime enforces it regardless of whether the remote tool's own schema lists a timeout; the kwarg is consumed by the runtime, not forwarded), now documented so it's discoverable. A timed-out leg throws a catchable error, so (fallback:) degrades gracefully and the rest of the run continues — the right tool for a partial-tolerant gather.
• RemoteMcpConnector honors cancellation. An aborted dispatch (per-op timeout= or run # Deadline:) now cancels the in-flight RPC promptly instead of leaving it pending on the subprocess until the connector's internal callTimeoutMs — matters for a serial-subprocess connector where a hung request could delay the next dispatch.
