…ion (#1) * fix: return a self-describing 404 for an unknown streamable-http session StreamableHTTPSessionManager answered a request for a missing or credential-mismatched session with a bare "Session not found" -- the same misleading-error problem modelcontextprotocol#19/modelcontextprotocol#26 already fixed for SseServerTransport's equivalent case (a redeploy or expiry invalidating every connected client's session_id at once), just not ported to this transport. Both call sites now share one message via _session_not_found_response(), built once so the "unknown session" and "credential mismatch" cases (which must answer identically -- see the comment) can't drift apart. Verified: full suite 1140 passed / 0 regressions (95 skipped, 1 xfailed, 2 pre-existing collection errors for the unrelated optional `websockets` extra, not installed in this environment) plus ruff and pyright clean. * fix: address review -- comment direction, unvalidated input note, expire coverage - _session_not_found_response's comment said "callers below" / "check above" -- true when this sat inline in sse.py, backwards once hoisted to a module-level function above both call sites. Converted to a docstring, direction fixed. - session_id here is the raw, client-supplied mcp-session-id header, never validated against SESSION_ID_PATTERN (only IDs the server mints are) -- unlike sse.py's session_id.hex, which is already UUID-validated. Safe (JSON-escaped, application/json, truncated to 64 chars matching the file's existing convention) but the docstring now says so, rather than leaving it to be re-derived later. - Test now asserts "expire" is covered, not just "restart" -- the one genuinely new clause this message adds over the sse-side wording (this transport has a session_idle_timeout; sse doesn't), which was the one claim the prior substring checks didn't actually verify. --------- Co-authored-by: oliver <oliver.sampson@gitterdan.ai>
