Apply contextual classification

Core meaning

Capability purpose: Preserve how an object relates to operating context without confusing context with ownership, access, or permanent identity.
Meaningful outcome: A current contextual relation is established or archived with provenance and historical continuity.
Boundaries — includes: target/context validation, apply, archive, reapply, provenance, temporal scope, and active/history views.
Boundaries — excludes: creating Roles or Modes, setting session-wide active context, access control, and assigning an organizing label.
Terms and concepts: Role and Mode are Cotton context concepts; an attachment expresses relevance, not permission.

Actor: The owner or a process acting under confirmed authority.
Command / intent: Apply or remove a Role or Mode context on an object.
Current state: The object, context value, authority, and active relation state are determinable.
Policies / invariants: Context never grants access; owner scope is consistent; silent inferred tagging requires confirmed authority; removal preserves history; concurrent contexts are allowed; inferred context does not silently become persistent preference or truth.
Transition: Validate target and context, create an active relation or archive the active relation, and record provenance/time bounds.
Result: A traceable active or archived contextual relation, or reasoned rejection.
Events / effects: Filtering, retrieval, and History may use the active or historical relation according to purpose.
Unknowns: View-specific AND/OR filter behavior is not universal.

Default views use active relations; history views may include archived relations.
