RESULT: FAILED

FILES CHANGED:
- jq_interpreter/parser.py
- jq_interpreter/evaluator.py

SUMMARY:
Fixed scalar indexing errors, optional access, range, common builtins, interpolation, nested `elif`, and `try` parsing. Project tests pass: 32 passed. Scoped conformance remains failing: PARSE-003 191/408 passed; PARSE-004 92/211 passed.

BLOCKERS:
- Broad evaluator functionality remains incomplete, especially advanced builtins, assignments, function scoping, and control semantics.

FAILURE_SUMMARY: Scoped conformance criteria still fail.

FAILURE_DETAIL: Both authoritative checks ran successfully but reported substantial failing corpus cases. Further general evaluator and parser implementation is required before rerunning this build step.
