Direct answer

A browser-local adapter marketplace is a user-controlled catalog of small skill packages. The user downloads only compatible, signed, source-described adapters and applies them locally to a matching base model.

Marketplace contract

FieldPurpose
Base familyPrevent applying an adapter to the wrong model
Tokenizer digestPrevent semantic incompatibility
Tensor layout checksumPrevent shape mismatch
License and sourcePreserve legal and provenance evidence
Evaluation cardShow what the adapter actually improves
Resource profileLet the user choose frugal packages
Revocation and retirementRemove stale or superseded skills

Local install flow

pseudocode
PROCEDURE install_adapter(adapter_package, local_base_model)
    REQUIRE adapter_package.base_family == local_base_model.base_family
    REQUIRE adapter_package.tokenizer_checksum == local_base_model.tokenizer_checksum
    REQUIRE adapter_package.tensor_layout_checksum == local_base_model.tensor_layout_checksum
    REQUIRE VERIFY_SIGNATURE(adapter_package)
    REQUIRE USER_ACCEPTS_LICENSE(adapter_package.license)

    result <- VALIDATE_ADAPTER_LOCALLY(adapter_package)
    IF NOT result.ok
        RETURN REJECT(result.error)
    END IF

    STORE_IN_LOCAL_REGISTRY(adapter_package)
    RETURN READY_FOR_SHADOW_TEST(adapter_package)
END PROCEDURE

Why this fits ModelBreeder

It combines the Four Fs: fast local load, flexible skills, frugal adapter size, and federated distribution without centralizing private data.
