Status: IN
The greedy output stack extends single-pass streaming from scalar accumulation to structured output construction: the stack serves as a bounded accumulator enabling per-element include/revise/skip decisions while maintaining output invariants — generalizing streaming's extend-or-reset pattern from scalar state to sequence-building state.
Connects an orphan greedy pattern to the streaming paradigm via accumulator generalization
