Overview

Narrowing key for an indexed read receiver[key] where both the receiver and the key are stable enough to address. The value of the map at this key is the narrowed type the next read at the same address MUST observe.

  • receiver_kind ∈ {:local, :ivar} — the analyzer only tracks reads against a local or instance variable today.
  • receiver_name is the variable's Symbol.
  • key is the Ruby value of the literal index (Symbol / String / Integer). Non-literal keys (params[field]) are not recorded; they have no stable address.
