RESULT: FAILED

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

SUMMARY:
- Added lexical binding shadowing, caller-scoped filter arguments, assignment validation, date parsing, `with_entries`, and `bsearch` support.
- Local tests: 32 passed.
- Scoped conformance still has failures in both PARSE-003 and PARSE-004.

BLOCKERS:
- Authoritative selectors remain incomplete, primarily numeric semantics, advanced builtins, path handling, and function argument behavior.

FAILURE_SUMMARY: Scoped conformance acceptance checks still fail
FAILURE_DETAIL: The implementation improved several clustered failures, but both declared conformance assertions continue reporting nonzero failures. Further evaluator work is required before rerunning the acceptance gates.
