35 test cases covering all five public functions: steward_align (pass-through, all five misalignment signals, empty input, json_get field extraction, redirect shape), steward_validate_imprint (standard tools, platform-only tools with/without platform_auth, auth=false string), steward_cgi_check (all four gated actions, non-gated actions, empty action, action name echoed in response), and steward_get_mission (non-empty, contains "integrity", not an error object). Also documents the known bug surface from the code review: the && operator in steward_get_mission and the non-Config fallthrough — tests are written against the actual runtime behaviour so they will catch regressions when those bugs are fixed.
