A host cannot tell a run somebody is playing from one nobody has looked at in an hour, so it cannot end the second without guessing. The hub now answers the address socket with a second line, `viewers <n>`, counting clients that are streaming. Init reads it alongside the address and sends a new `viewers` message to the host when the count changes. A reader that takes only the first line gets the address exactly as before, a server that never writes the second line is still read, and a host that does not know the message skips it, so either end can ship first.
crates/
Shared Rust: a library another crate in this repo depends on. A binary someone
runs goes in apps/; shared JS/TS goes in
packages/. The split is by what a thing is, not by what
language it is written in — same rule on both sides of the repo.
Empty today. Components move here one at a time as they are opened.
Two rules
Every version is pinned in the root Cargo.toml. A member writes
tokio.workspace = true and never a version, so two crates in this tree cannot
disagree about a dependency.
Nothing here may depend on anything closed, or name it. This repo is public. A crate that needs a private component is in the wrong repo, and a comment explaining who calls this wants a category noun — "the caller", "a supervising agent" — rather than a name. The requirement is the interesting part; who currently satisfies it is not.
