|
|
|
behavior differences, a three-tier tool loading architecture across four client
|
|
|
|
|
surfaces, the artifact execution layer (Claude-inside-Claude API calls, session-scoped
|
|
|
|
|
storage, MCP endpoint access), and MCP connector state as an architectural variable.
|
|
|
|
|
Based on 50+ manual tests with empirical verification across all platforms. Edition 1.4
|
|
|
|
|
includes contributions from two external researchers.
