Bucketing attribute selection: Missing bucketing attribute yields no identity · case 04

Users without an org attribute are all treated as unbucketable instead of using their key.

Member previewVariant 4 · 3 implementations · 8 checks per implementation

Case contract

The bucketing identity is user[bucket_by] when bucket_by is non-empty and present, else user["key"]. Booleans, None and non-scalar values are unbucketable -> [None, 0]; integral floats use their integer form, other floats are unbucketable; ints and strings are used verbatim via str(). Return [identity, crc32(flag_key + "." + salt + "." + identity) % 100000].

Why this case matters

Bucketing by organisation or device keeps whole accounts in one variant; the identity must be stable.

This sample comes from the broken implementation of a controlled reproducer.
