Case contract

contexts maps kind -> key. Empty input or any empty key -> None. A context containing only the kind "user" is keyed by the bare user key. Otherwise join, over kinds in sorted order, kind + ":" + escaped key with ":", where escaping replaces "%" by "%25" and then ":" by "%3A".

Why this case matters

Canonical context keys feed bucketing and caches; two spellings of one context split its traffic.
