• merge profile environment, headers, and party bindings with documented precedence and typed validation
• cover captured dynamic/generated resolve equivalence, List, record/variant encoding, and failure timing

Verification

• ./mvnw -B -ntp spotless:check
• ./mvnw -B -ntp test (43 tests)
• ./mvnw -B -ntp verify
• ./mvnw -B -ntp install
