Control Notes

1. Liveness signal

Liveness signal is the point where public documentation must become an operating rule. In this package, it means heartbeat or connection behavior proves only that a session is alive enough to receive messages. The practical action is to log heartbeat, close reason and reconnect timestamp without secrets. The unresolved edge is whether the library masks missed heartbeat events, so the article keeps that edge explicit instead of turning it into a reward claim, licensing claim, approval claim, safety guarantee, recovery promise, platform ranking or price implication.

2. Message continuity

Message continuity is the point where public documentation must become an operating rule. In this package, it means sequence handling and channel ordering determine whether a local book or order view is stale. The practical action is to treat any detected gap as a reconciliation trigger. The unresolved edge is whether dropped messages occurred before local detection, so the article keeps that edge explicit instead of turning it into a reward claim, licensing claim, approval claim, safety guarantee, recovery promise, platform ranking or price implication.

The operating test is narrow.

3. Authenticated scope

Authenticated scope is the point where public documentation must become an operating rule. In this package, it means private feeds require token or authenticated setup separate from public market data. The practical action is to store only token request metadata and channel names. The unresolved edge is whether token expiration differs across worker processes, so the article keeps that edge explicit instead of turning it into a reward claim, licensing claim, approval claim, safety guarantee, recovery promise, platform ranking or price implication.

The operating test is narrow.

4. Trading action boundary

Trading action boundary is the point where public documentation must become an operating rule. In this package, it means WebSocket order placement is not the same as a final order-state record. The practical action is to query final REST or private-feed state after lost responses. The unresolved edge is whether a partial fill changed the order meaning before reconnect, so the article keeps that edge explicit instead of turning it into a reward claim, licensing claim, approval claim, safety guarantee, recovery promise, platform ranking or price implication.

The operating test is narrow.

5. Reconnect path

Reconnect path is the point where public documentation must become an operating rule. In this package, it means a reconnect can replay, skip or reorder locally observed state depending on client behavior. The practical action is to reset subscriptions and compare a fresh snapshot before resuming automation. The unresolved edge is whether stale local strategy state survives the reconnect, so the article keeps that edge explicit instead of turning it into a reward claim, licensing claim, approval claim, safety guarantee, recovery promise, platform ranking or price implication.

The operating test is narrow.

6. Evidence hygiene

Evidence hygiene is the point where public documentation must become an operating rule. In this package, it means debug logs can expose channel names, order ids and account metadata. The practical action is to keep source URL, channel, non-secret order id, event and final state only. The unresolved edge is whether screenshots reveal balances or private strategy timing, so the article keeps that edge explicit instead of turning it into a reward claim, licensing claim, approval claim, safety guarantee, recovery promise, platform ranking or price implication.

The operating test is narrow.

Known Unknowns

• whether the library masks missed heartbeat events
• whether dropped messages occurred before local detection
• whether token expiration differs across worker processes
• whether a partial fill changed the order meaning before reconnect
• whether stale local strategy state survives the reconnect
• whether screenshots reveal balances or private strategy timing

Practical Takeaway

Kraken and Coinbase both expose WebSocket feeds that can support trading automation, but neither feed should be treated as a complete order-risk record on its own. Kraken WebSocket v2 documentation separates market-data channels, trading endpoints and authenticated-token setup, while Coinbase Exchange WebSocket documentation describes channel subscriptions, sequence handling and connection behavior for exchange feeds. The useful comparison is to prove heartbeat or liveness behavior, sequence continuity, reconnect path, authenticated channel scope, REST reconciliation and non-secret logging before a bot relies on either venue after a disconnect. The article stops at the evidence boundary. It helps the reader decide what to inspect next without converting public documentation into a promise that a private account, wallet, API key, pool route, stablecoin balance, tokenized asset or policy framework will work under every future condition.
