What a sample holds
Value enum
HKCategoryValueAppleWalkingSteadinessEvent — the enum Apple’s page for appleWalkingSteadinessEvent names. Every category type’s enum is on the HKCategoryValue reference.
Aggregation style and unit family apply only to quantity types. For a category type the dataset records neither, because the concept does not apply — not because Apple declined to say.

No. Apple’s documentation states that these samples are read-only:
