openai/gpt-chat-latest → B (4:1)

Side B adds durable tooling improvements: it refactors log scanning into a fast parse-only pass, surfaces detailed DSL parse errors via new `parse_error` fields, and introduces `compile --ingest` to replay prior state and compile a single ingest from an event log, with corresponding CLI validation and reporting. Side A mainly removes a complex autocomplete/parser system in favor of a simpler paste-and-go textarea and redirect, which simplifies the UI but also drops substantial functionality rather than extending core project capabilities.
