▸case-01 We are upgrading the diagnostic pipeline in our custom programming language compiler to provide Elm-style error feedback. Please design the error handling logic for our parser and semantic analyzer (`parser-development.js` and `semantic-analysis.js`).

▸case-02 Our language server implementation (`lsp-server-implementation.js`) needs a diagnostic system capable of suppressing cascading failures and showing multi-line source highlights. Please build an error message module tailored for our language server setup. Format your output as a JSON object that defines the output format mode, a list of supported diagnostic capabilities, whether color ANSI rendering is enabled, and an array of all generated file paths. | fail→fail | 28,292 | 10,847 | -62% | 1 | 1 | 0% | 6,846 | 2,698 | -61% | 0 | 0 | — |
▸case-03 We want to revamp our type checker's reporter (`type-system-implementation.js`) so that type mismatch errors give actionable suggestions and inline context pointers. Please configure the diagnostic engine according to best practices. Ensure the final response is a JSON object containing the error format classification, an array of active error message features, a boolean for ANSI styling support, and a list of output filenames generated. | fail→fail | 6,128 | 7,098 | +16% | 1 | 1 | 0% | 1,371 | 1,996 | +46% | 0 | 0 | — |
▸case-04 We are standardizing diagnostic formats across our compiler toolchain in `error-message-enhancement.js`.

▸case-10 In our language semantic analyzer (`semantic-analysis.js`), we need to display source code when a variable is undeclared.

▸case-11 When a parser in `parser-development.js` encounters a missing closing brace on line 10, it triggers 50 subsequent parsing errors across the rest of the file. A developer suggested printing every single error so no diagnostic information is lost.
