VPS kill switch

The cloud worker has its own kill switch in the web app (app.spectraterminal.com/worker). Pressing it does the same thing the desktop kill switch does on your machine, but on the worker side:

• Pauses every active webhook secret.
• Cancels any in-flight broker submissions.
• Disables new webhook acceptance until manually unlocked.

Why a separate switch

The desktop kill switch flattens your live positions. The cloud worker may control multiple accounts (Pro multi-account; Enterprise shared trading). Hitting either one independently is the design — you might want to halt automated trading without flattening manual positions, or vice versa.

Triggering automatically

The worker fires its own kill switch when:

• A secret's daily-loss cap is breached.
• The broker connection reports auth_failed repeatedly (usually rotated API key).
• An admin manually pauses the secret.

Unlocking

Web app → Worker → Resume. You re-confirm the daily-loss cap and any breached secret stays paused until reset individually. Resume is audited — every unlock is logged with timestamp and source IP.

Latency to take effect

A kill switch press propagates to all accepting secrets within < 200 ms typically. If a request was already mid-broker-call when the press happened, that submission may complete; the next one is rejected.
