Interactive demo with synthetic data. This environment demonstrates Terra PPC workflows using synthetic advertising, seller-business, financial and economics data. Actions remain inside this demo and are not sent to Amazon or any external advertising or selling account.

Safety & Circuit Breaker

The circuit breaker stops Auto actions when a cycle looks wrong; emergency controls, the emergency revert and the published-strategy restore act immediately. Everything here applies to this account and marketplace only.

Checks for the next cycle

Every check passes; nothing trips at the next cycle.

Circuit breaker checks for the next cycle
Check	Result	Value / limit	Detail

Data freshnessBefore the rules run	Passed	On/off check	Latest full day of advertising data: 2026-09-24.
Scope consistencyBefore the rules run	Passed	On/off check	Every target and search term belongs to Terra Home & Packaging / US.

Auto actions in one cycleOn the planned Auto actions	Within limit	18 / 25	18 Auto actions planned (trips above 25).
Spend one cycle could moveOn the planned Auto actions	Within limit	28.9% / 40%	Planned Auto actions could move 28.9% of the scope's average daily ad spend (trips above 40%).
Budget moved in one cycleOn the planned Auto actions	Within limit	5.5% / 40%	Planned budget changes move 5.5% of the enabled campaigns' daily budgets (trips above 40%).
Conflicts in one cycleOn the planned Auto actions	Within limit	1 / 12	1 conflict resolved in this evaluation (trips above 12).

Execution failures are counted while the cycle applies its changes: more than 3 failed Auto actions trip the breaker and send the rest of the queue to the Review queue.

Emergency controls

All off

Scope-level switches for this account and marketplace only. They take effect as soon as the change is confirmed.

Pause all automationAuto actions of every campaign go to the Review queue instead of applying. Recommendations can still be applied by a person.
Disable bid increasesHolds every bid increase and hourly bid-up — from Auto actions, approvals and AI/MCP proposals. Bid decreases still apply.
Disable budget increasesHolds every daily budget increase, including reallocations that raise a budget. Decreases still apply.
Disable placement increasesHolds every placement adjustment increase. Decreases still apply.

Change a switch to apply it.

Circuit breaker limits

Limits apply from the next cycle. Saving writes one Change Log entry that can be undone.

Circuit breakerOn by default. When off, cycle limits never stop Auto actions; emergency controls and business guardrails still apply.

Max Auto actions per cycle

More Auto actions than this in one cycle trips the breaker.

Max spend moved per cycle (%)

Share of the scope's average daily ad spend the Auto actions may move.

Max budget moved per cycle (%)

Share of the enabled campaigns' daily budgets Auto budget changes may move.

Max conflicts per cycle

Conflicts the resolver may settle before the cycle looks wrong.

Max execution failures per cycle

Auto actions that fail to apply before the rest go to review.

Spend anomaly above the 7-day average (%)

Latest-day spend this far above the previous 7-day average trips the breaker.

Stale data simulation

DEMO

Shows how the circuit breaker reacts when advertising data is out of date.

Simulate stale advertising dataDemo control: the next cycle's data check fails and the circuit breaker trips, so decisions on old numbers are not applied. Turning it off lets the data check pass again; a tripped breaker still needs a reset.

Data freshness check now: Latest full day of advertising data: 2026-09-24.

Breaker events

Trips, warnings and resets of this scope, newest first.

No breaker event yet

Trips, warnings and resets appear here. Try the stale data simulation, then run a cycle.

Emergency revert

Undoes the Auto actions of the latest cycle, newest first. An action whose entity changed afterwards is left as it is and reported. It runs once per cycle.

The latest cycle applied no Auto actions, or they were already reverted.

Nothing to revert

Auto actions of the latest cycle appear here after a cycle applies them in an Auto campaign.

Restore the published strategy

Throws away unpublished rule and guardrail edits by restoring the published version. Rules, business guardrails, strategies, campaign modes and circuit breaker limits return to it.

Published: v2 · Tighter bid steps, budget scaling on (Sep 23, 2026 · 3:40 PM)

What a restore would change

Nothing: the current setup matches v2.

The restore is recorded as a new version; earlier versions stay in the history.

Business guardrails

They read seller-business context to hold advertising scale actions. They never pause ads and never change listings or inventory.

What each guard does

Inventory GuardOnBelow 5 days of cover, scale actions are held. From 5 to 10 days — the review tier — Auto scale actions need approval and go to the Review queue instead of applying. Days of cover use the sales of the last 7 days.
Listing GuardOnHolds new scaling recommendations when an advertised listing is SUPPRESSED or INACTIVE. Never fixes the listing.
Cost Increase GuardOnWhen an advertised SKU's unit cost rose 10% or more within 30 days, its Modeled Break-even ACoS falls. Scaling is held while the ACoS is above the new break-even, and a cost review recommendation is raised.
Break-even GuardOnProfit Guard upgrade: holds scaling when the ACoS of the target or campaign being scaled is above the Modeled Break-even ACoS. Never pauses campaigns.
Financial Margin GuardOnHolds scaling for an advertised SKU whose 30-day Modeled Net Margin (actual fees) is below 0.0%.
Refund reviewOnAn advertised SKU with refunds at or above 5.0% of seller gross revenue and at least $50.00 ad spend gets an investigation recommendation. It never holds an action.
Emergency controlsAll offScope-level switches on the Safety page that stop bid, budget or placement increases from any source. They are the switches in Emergency controls above.

Business guardrails (seller context)

When a guardrail’s data is outside the demo scope its outcome is UNKNOWN: it is not evaluated and never treated as a pass or as zero. Held actions are recorded as ACTION_SKIPPED_BY_GUARDRAIL when an evaluation or scheduled cycle runs. Try the Inventory Guard
