1# Host entropy

4# The package's only host binding for randomness: entropy/native.c natively and
5# entropy/webcrypto.js in JavaScript. generation.bend reads source words from
6# it; trace_context.bend never does.

10# One word from the host's cryptographic source: WebCrypto in JavaScript and
11# the operating system's generator natively. Fail code 1 means unavailable and
12# code 2 means source-failure in JavaScript; natively the code is the host
13# errno with its strerror text. The pure codec never calls it implicitly.
