feat: route SEP-2260 associated server requests to the originating SSE stream ( #1029 ) ...
* feat: implement SEP-2260 require server requests to associate with client requests
* feat(service): attach originating request id to in-handler outbound requests (SEP-2260)
Reuses the ORIGINATING_REQUEST task-local from #1027 ; the marker rides
the request's non-serialized Extensions so the streamable HTTP server
can route associated requests to the originating SSE stream.
* feat(transport): route associated server requests to originating SSE stream (SEP-2260)
* test: end-to-end SEP-2260 stream routing over streamable HTTP
* test: register SEP-2260 routing test with required-features; drop dead list_tools
* docs: document SEP-2260 association requirement and stream routing
* docs: fix redundant explicit link on OriginatingRequestId
* docs: note marker is role-agnostic; add reason to deprecated expect
Review follow-ups: the OriginatingRequestId rustdoc now states the marker
is attached for both roles with only the server transport reading it, and
the test's deprecation suppression carries a reason per house style.
* docs: condense inline comments to repo convention
Trims multi-line inline comments added in this branch down to the terse
one-to-two-line style used elsewhere in the codebase, keeping only the
non-obvious rationale (spec references, fallback invariant, version choice).
* docs: condense SEP-2260 rustdoc sections
Tightens the duplicated per-method association section from eleven lines
to five, and trims the marker and SessionManager docs to the same
information in fewer words.
* docs: single-source SEP-2260 caller requirements on OriginatingRequestId
* feat(service): reject unassociated server-to-client requests on the client (SEP-2260)
Implements the client receive-side of SEP-2260: restricted server
requests (sampling/createMessage, roots/list, elicitation/create)
received while the client has no outbound request in flight are
answered with -32602 invalid params instead of being dispatched to the
handler. Gated on negotiated protocol >= 2026-07-28; ping is exempt.
With a request in flight we cannot tell which one the server request
belongs to (SEP-2260 defines no wire field), so this is a deliberate
under-approximation of the spec's SHOULD; exact stream-based
enforcement for streamable HTTP needs receive-side provenance plumbing
and is left as a follow-up.
