 - [ ] 3.8 Package the authorized SCUM map asset, identity/version, verified world bounds, layer metadata, and coordinate transform, with fixture tests for known points, out-of-bounds/non-finite coordinates, and adapter incompatibility.
 - [ ] 3.9 Declare only verified typed RCON templates for supported Fame/currency/notification/gift operations and a version-scoped gift item catalog; omit any command whose execution and confirmation semantics remain unknown.
 - [ ] 3.10 Declare a guarded preserving XML mutation only after the real XML source and named attributes are proven; expose `855` only as a reviewed named-attribute preset and never as a database column, generic integer field, or guessed mapping.
-- [ ] 3.11 Add immutable asset/digest declarations and plugin package validation; defer generated Run-package execution wiring until the complete protocol/result envelope and independent Run capability evidence in group 4 are frozen.
+- [x] 3.11 Add immutable asset/digest declarations and plugin package validation; defer generated Run-package execution wiring until the complete protocol/result envelope and independent Run capability evidence in group 4 are frozen.
 - [x] 3.12 Remove SCUM Workflow/projection declarations and obsolete page/action declarations from the plugin manifest while preserving the five required pages and AI configuration assistance.
 - [ ] 3.13 Match the observed fingerprint/evidence matrix against each completed adapter, add per-capability compatibility/release-gate tests, and leave every unsupported or ambiguous player/squad/vehicle/flag/position/write capability disabled.
