| Code | Severity | Meaning |
|------|----------|---------|
| `E000` | error | File cannot be read (lint). |
| `E001` | error | Syntax error (tokenizer). |
| `E001` | error | *Reserved* — tokenizer/syntax error. Not currently emitted: lexer-level failures surface through the parser as `E002`. The code is held so `E002` keeps its meaning if a distinct tokenizer diagnostic is added later. |
| `E002` | error | Parse error (parser). `--lint --json` reports the first one. |
| `E100` | error | Uncaught runtime error (category code; see note below). |
| `W001` | warning | Unused variable. |
