Coding-Hard-Json-Pointer

The model receives the prompt (and optional system message). The run uses scorer javascript_function_tests with the JSON configuration below. Pass/fail and partial credit are determined entirely by that scorer against the model output; no human grading.

Return JSON only with a string field named code. The code must be dependency-free JavaScript, define the requested function in the top level or module.exports, and include no markdown, imports, require, timers, network, filesystem, eval, or placeholders.

Implement function applyJsonPatch(doc, ops) supporting JSON Patch add, remove, and replace with JSON Pointer paths. Return a patched deep copy and do not mutate doc.

Your JSON must look like {"code":"function applyJsonPatch(...) { ... }"}.
