v1.8.17 — closed-value tool parameters reach the MCP schema
drs_behavior (cluster_create, cluster_configure), rule_type (create_drs_rule) and binding (create_dvs_portgroup) were typed str, with their valid values named only in prose. An MCP client sees the schema, not the prose, so a model had to guess the spelling.
They are now Literal[...], and a regression test pins each enum against the set the ops layer actually validates against (_VALID_DRS_BEHAVIORS, _CREATABLE_RULE_TYPES, _VALID_BINDINGS), so the two cannot drift apart.
