A file is UTF-8 text, lines split on `\\n` (strip a trailing `\\r`).\n2. Blank lines and lines whose first non-space character is `#` or `;` are comments.\n3. `[name]` starts a section. Names are trimmed and case-insensitive (store lower-case). Keys before any section belong to section `\"\"`. Re-opening a section adds to it.\n4. `key = value` or `key: value` (first `=` or `:` wins). Keys are trimmed, case-insensitive (lower-case). A duplicate key in the same section: the last one wins.\n5. Unquoted values are trimmed; an inline comment starts at ` #` or ` ;` (whitespace then # or ;) and runs to end of line.\n6. A value wrapped in double quotes is taken literally (no inline comments), with escapes `\\\"` `\\\\` `\\n` `\\t`. Any other escape is an error. Text after the closing quote other than whitespace or an inline comment is an error.\n7. A line that starts with whitespace and follows a key line is a continuation: its trimmed text is appended to the previous (unquoted) value with a single space. Continuations after a comment/blank line or a section header are errors.\n8. `${key}` refers to a key in the same section; `${section.key}` to another section. References are resolved after the whole file is parsed, recursively; quoted values are interpolated too. `$$` is a literal `$`. An unknown reference or a cycle is an error.\n9. Typed accessors: `true/yes/on/1` and `false/no/off/0` (case-insensitive) are booleans; anything else is an error for `getbool`.\n10. Any other malformed line (no separator, empty key, unterminated `[`) is an error.\n\nAPI (module `rconf.py`):\n- `parse(text) -> dict[str, dict[str, str]]` with fully resolved values.\n- `getbool(cfg, section, key) -> bool`\n- Errors raise `RConfError(msg, line)` where `line` is the 1-based line number (for an unknown reference: the line of the value containing it; for a cycle: the line of any value in the cycle).\n\"\"\"RCONF parser - TODO: implement per SPEC.md\"\"\"\nclass RConfError(Exception):\n    def __init__(self, msg, line):\n        super().__init__(f\"line {line}: {msg}\"); self.line = line\n\ndef parse(text):\n    raise NotImplementedError\n\ndef getbool(cfg, section, key):\n    raise NotImplementedError\n", "exit_code": 0, "status": "completed"}}
