eight sidecars hand-rolled the same port capture — byte-identical once
the app name is normalised — and six repeated the same auth-and-forward
router. createSidecarProxy collapses both into one call and covers the
variants the others need: a ws:// url for music and vault, an onRegister
hook for opencode.
the wallet adopts it first: two files become one, 54 lines of router
become 16, and hono no longer needs a side-effect import to capture the
port. the no-body-parsing, no-body-logging rule moves into the factory
with its rationale, since that restraint is what keeps unlock
passphrases and macaroons out of the platform process.
costs 31 net lines today and pays back from the second adopter on.
