+Feature: Disabled flag evaluation
+
+  # Test coverage for disabled flag behavior. A flag with state=DISABLED resolves
+  # successfully with reason=DISABLED and no value or variant (SDK uses code default).
+  # Relates to: https://github.com/open-feature/flagd/issues/1965
+
+  @rpc @in-process
+  Scenario Outline: Evaluating a disabled flag returns reason DISABLED and code default
+    Given an option "cache" of type "CacheType" with value "disabled"
+    And a stable flagd provider
+    And a <type>-flag with key "<key>" and a default value "<default>"
+    When the flag was evaluated with details
+    Then the resolved details value should be "<default>"
+    And the reason should be "DISABLED"
+
+    Examples:
+      | key                   | type    | default |
+      | disabled-boolean-flag | Boolean | false   |
+      | disabled-string-flag  | String  | bye     |
+      | disabled-integer-flag | Integer | 1       |
+      | disabled-float-flag   | Float   | 0.1     |
+
+  @rpc
+  Scenario: Bulk evaluation includes disabled flags with reason DISABLED
+    Given an option "cache" of type "CacheType" with value "disabled"
+    And a stable flagd provider
+    When all flags were evaluated in bulk
+    Then the bulk evaluation result should contain a flag with key "disabled-boolean-flag" and reason "DISABLED"
+    And the bulk evaluation result should contain a flag with key "boolean-flag" and reason "STATIC"
+
+  @in-process
+  Scenario Outline: Flag disabled in one flag set, enabled in another
+    Given an option "cache" of type "CacheType" with value "disabled"
+    And an option "selector" of type "String" with value "<selector>"
+    And a stable flagd provider
+    And a Boolean-flag with key "cross-flagset-flag" and a default value "false"
+    When the flag was evaluated with details
+    Then the resolved details value should be "<resolved_value>"
+    And the reason should be "<reason>"
+
+    Examples:
+      | selector                     | resolved_value | reason   |
+      | rawflags/disabled-flags.json | false          | DISABLED |
+      | rawflags/selector-flags.json | true           | STATIC   |
