## Requirements & limits

- The reviewed package metadata is 0.1.5 and classified Alpha; it declares Python ^3.6 and docopt ^0.6.2. As checked on 2026-10-20, v0.1.5 is the latest tag and PyPI release (uploaded 2021-09-17) and there are no GitHub releases; the reviewed 2023-04-10 commit is still the main head, GitHub’s last recorded push was 2023-12-10, the repository is not archived and the README does not mark it as maintained, superseded or archived.
- README support is limited to HBC versions 59, 62, 74 and 76. Supply a compatible Hermes bytecode bundle.
- This is a bytecode assembler/disassembler, not complete original-JavaScript recovery. Overflow patching is listed as future work. MIT-licensed.
