• Executable: ./jq -c '<program>'; compact JSON lines on stdout.
• Exit codes: 0 success, 3 compile failure, 5 runtime failure; diagnostics on stderr.
• Standard-library Python only; no external jq, dependencies, networking, or persistence.
• Modules: CLI, lexer, parser/AST, evaluator streams, runtime values, builtins, paths/assignment, diagnostics.
• Preserve generator ordering, multiplicity, backtracking, immutable transformations, and partial output.
