Extract (source_text, ast_node, start_line_index, end_line_index) for each TOP-LEVEL function definition only.

Convert '\\x68\\x65' inside STRING literals to ASCII. Skips bytes literals.

Decode patterns like: ''.join(chr(x ^ y) for x, y in zip([0xde, 0xf9, ...], [0x8d] * 11)) ''.join(chr(x ^ y) for x, y in

Walk the AST and ensure no compound statement has an empty body. Empty bodies (if/while/for/with/try/except/def/class) are invalid Python —

Extract list of ints from chr(x) for x in [...] or map(chr,[...]).

Parse the VM class from source and return its opcode table.

Convert a chain of walrus expressions into assignments if safe. Also handles non-walrus expressions that have side effects by keeping

Match: bytes([VAR ^ KEY for VAR in PARAM]).decode(ENC) or: getattr(bytes([VAR ^ KEY for VAR in PARAM]), 'decode')(ENC) Ret

Return names used as state variables in while-True dispatcher loops.

Detect names used as state variables in while-True dispatcher loops. These must NOT be inlined as constants.

Pre-pass: flatten top-level/function-level walrus BoolOp chains.

Fold constant join/chr patterns: "".join(["a","b","c"]) -> "abc" "".join(chr(x) for x in [N...]) -> "..." (if

When a variable is assigned a list of string constants, and then joined: parts = ["a", "b", "c"] code = "".join(parts)

Within function bodies, collapse single-use variable chains: a = expr b = a (a used only here) → b = exp

Return the code objects from the dump.

Detect the current platform.

Get Python version string (e.g., '3.11').

Score 0.0–2.0 based on what fraction of identifiers look mangled. Returns higher score for unusually short average identifier length.

A large file with suspiciously few imports gets a score boost.
