 - **Bulk recompute task.** Celery beat schedule that walks the catalog in shards, emits suggestions, applies the auto-approve set, queues the rest for review.
 - **Webhook ingest.** Inbound `products/update` webhook with HMAC verification (already implemented in `shopify/client.py:verify_webhook`) drives a recompute task for the affected SKU.
 - **Rate-limit-aware Shopify client.** Backoff on `X-Shopify-Shop-Api-Call-Limit`. Batch variant updates where possible.
+- **Per-merchant automation suspend.** Emergency-stop flag on the merchant row. Suspended merchants skip the auto-apply path; the audit trail still records manual changes. Complements rollback — rollback fixes the past, suspend prevents the next move.

 - **Pricing-signal layer.** Replace the toy `demand_signal - inventory_pressure` proposal with something that reads real signals. The guardrail layer is the safety surface — the proposal is swappable.
 - **Per-merchant policy.** Today `MerchantPolicy` is constructed with module defaults. Move to a per-merchant config row.
+- **Asymmetric guardrail caps.** Split `max_change_pct` into `max_increase_pct` and `max_decrease_pct`. Most merchants want prices to fall slower than they rise.
 - **A/B price testing.** Treatment / control groups, lift measurement against an audited baseline.
 - **Margin-based reporting.** Slice realized margin by SKU, by category, by guardrail-fired rate.
