Maximum-fidelity Python source reconstruction from Nuitka `.nbc` / `NBC/2` files produced by `nuitka_decompiler.py`. Use when the user pastes or references a `.nbc` file, an `AI_READY_NBC` bundle, sections such as `@MOD`, `@CONSTS`, `@RAW_CHUNK`, `@OPS`, `@ASM`, `@FORENSICS`, `module_code_*`, `mod_consts[N]`, or asks to rebuild Python source from a Nuitka C-compiled module. The goal is evidence-backed reconstruction, not guaranteed perfect 1:1 recovery; uncertain spans must be marked.

# Nuitka NBC -> Python Source

Rebuild Python source from a Nuitka `.nbc` file with maximum fidelity to the
original module. Treat the `.nbc` as forensic evidence, not as a normal Python
bytecode listing. Nuitka may have removed comments, formatting, some local
names, and may have inlined or optimized logic; never promise exact 1:1 output
when the evidence is incomplete.

If the user needs to generate inputs first, prefer:

```bash
python nuitka_decompiler.py --source target.exe --output OUT --only app,app.* --nbc-only
```
