RESULT: FAILED

FILES CHANGED:
- jq_interpreter/evaluator.py

SUMMARY:
Improved shared operator error handling, defined-or fallback, unary negation, `nth`, `pick`, `input`, datetime diagnostics, `_strindices`, and `bsearch`. Project tests pass: 32 passed.

Acceptance checks remain failing:
- PARSE-003: 344 passed, 110 failed, 1 errored
- PARSE-004: 156 passed, 54 failed, 1 errored

BLOCKERS:
- Broad evaluator gaps remain in assignments, closures, deep paths, numeric semantics, and additional builtins.

FAILURE_SUMMARY: Scoped conformance gates remain red.
FAILURE_DETAIL: The interpreter still fails substantial authoritative corpus coverage; further evaluator implementation is required before rerunning this build block.
