Cloudflare Durable: persist peer.namespace in attachment (state.n) in _restore

[marr]

Summary

After namespaced pub/sub (e.g. #162), AttachedState includes optional n (connection namespace) and _restore reads namespace || state.n || "". If the namespace is not written into the serialized attachment before setAttachedState, hibernation / attachment-only restore can deserialize a state with no n, yielding an empty namespace and triggering getPeers → "Websocket publish namespace missing." on close or pub/sub paths.

Suggested fix

In CloudflareDurablePeer._restore, after assigning state.i = peer.id (and any state.u updates), persist the namespace:

state.n = peer.namespace;
setAttachedState(ws, state);

This matches the intent of state.n on AttachedState and ensures the next serializeAttachment round-trip keeps the namespace across DO WebSocket hibernation.

Context

Consumers may work around this with a pnpm patch on dist/adapters/cloudflare.mjs (e.g. state.n = peer.namespace before setAttachedState). Upstream fix would allow dropping that patch.

Environment

• crossws with Cloudflare Durable Objects adapter, ctx.acceptWebSocket, peer restored from attachment without a fresh upgrade request carrying namespace.
