Run `JQ=./jq python3 sources/run_conformance.py`; candidate must emit JSON lines and use exit 3 for compile errors, 5 for runtime errors. Harness reports structural output matches and supports scoped execution via `--select REGEX --json`; exit 2 indicates harness faults. RESULT: SUCCESS FILES CHANGED: - jq_interpreter/ast.py - jq_interpreter/parser.py - jq_interpreter/evaluator.py - jq_interpreter/interpreter.py - tests/test_architecture.py SUMMARY: Implemented literals, comma generators, runtime errors, arrays, limits, BOM-tolerant input, diagnostics, and exit-code behavior. All 7 project tests and declared process acceptance checks pass. Identity conformance slice passes 2/2. BLOCKERS: - None
