📄 Description

Summary

Add inspect_erlang_beam / inspect-erlang-beam for one explicit local
FOR1/BEAM IFF file. The workflow returns chunk names and payload SHA-256,
Atom/AtU8 names, export/import/lambda tables with resolved atom names when
present, and the Code chunk instruction-set header.

It does not execute bytecode or require an Erlang installation. Missing optional
tables stay null. Malformed FOR1/BEAM headers, truncated chunks, and exhausted
budgets fail without partial success. LitT inflation and Attr/CInf external-term
decoding remain out of scope.

Usage

rea inspect-erlang-beam /absolute/path/to/app.beam --json

MCP: inspect_erlang_beam with an absolute path.

Tests

npm run check:fast
npm run test:local -- domain, parser, and service tests (8 passed)
npm run test:focused -- CLI, MCP, and filesystem tests (7 passed)
