seed 11Streaming JSON Repair & Buffer Playground: Baseline
Explore the core controls with stable inputs and visible assumptions.
Assumptions
The simulation is deterministic and intentionally simplifies provider and hardware behavior.
Failure injection
Stable baseline with no injected production fault.
