Ecommerce production rollout with Jev
Catalog copy, reviews, and promo banners need a keep / edit / hold decision before they go live. Recs, search rank, and inventory still own merchandising math. Jev judges language against your policy excerpt. It does not set prices or personalize a homepage.
This unofficial page is the production rollout slice of the ecommerce merchandising decisions pack. Intent: apply the Jev (TypeSafe System One) decision model to ecommerce merchandising decisions production rollout. Primary search language: Ecommerce Jev production rollout. Confirm patterns on docs.typesafe.ai. This site does not sell, issue, or proxy TypeSafe keys. Use a credential you already have from the console or a documented gateway.
Independent angle (cover ≠ clone): Claim/policy + merchandising action on catalog text — not a clone of a personalization-engine sitemap or recs API landing page.
Ecommerce use-case context
Production rollout for ecommerce merchandising decisions is Operate-pillar work: pin, shadow, canary, abort. It is not a launch-checklist clone of a rival “build with System One” guide — we only talk about this pack’s blast radius (publishing customer-visible copy or a live promo).
Hub: Use cases. Compare, when the other tool is the real job: ecommerce personalization.
Production Rollout inputs
Ship the contracted payload, the pinned id, and a documented safe default when the API is unavailable:
{
"item": { "id": "sku-88", "title": "Lose 10kg tea", "bullets": "Guaranteed results in 7 days." },
"policy": { "health": "No absolute health outcomes.", "stock": "Do not claim in-stock if inventory_flag is false." },
"flags": { "inventory_flag": true, "locale": "en" }
}Decision signals and actions
| Stage | What changes | Ecommerce rule |
|---|---|---|
| Shadow | Nothing customer-visible | PIM publish path unchanged; log Jev action. |
| Canary | One low-blast slice auto-acts | Enforce holds on health-claim SKUs only. |
| Abort | Auto-act off | New category or market → freeze auto-publish. |
Keep the workflow code you already designed:
def ecom_gate(ans, inventory_flag):
if not inventory_flag:
return "hold_stock" # code
act = ans["action"]
if act.confidence < FLOOR or act.choice == "other":
return "merch_review"
if ans["policy_ok"].noul < T_OK or ans["claim_risk"].score >= 2:
return "hold_legal"
return act.choiceDo not treat a Noul of 0.5 as a “medium” ecommerce merchandising decisions score — it means yes and no are equally likely. Conjunctions stay in your code.
Guardrails and escalation
Safe default if System One errors or confidence is low: do not publish customer-visible copy or a live promo. TypeSafe’s confidence-gated examples use a lower bar for recoverable reads than for irreversible actions. Those numbers are illustrations. For ecommerce merchandising decisions, treat publish as the high bar (publishing customer-visible copy or a live promo). Tune on labels — see offline evaluation.
Evaluation and rollout notes
Promotion gate = evaluation green on the pinned id + audit traces for the canary. Pin jev-1.13.0 (the versioned id) after you fit thresholds. jev-latest and the marketing line jev-1.13 can move. Log the response model. TypeSafe’s published list price for jev-1.13 is $0.042 per million input tokens (vendor claim — confirm on the models page); output tokens are free on that same page. Unused distractors still bill as input.
Official Python and JavaScript SDKs read TYPESAFE_API_KEY and retry documented 429/529. This site does not sell, issue, or proxy TypeSafe keys. Use a credential you already have from the console or a documented gateway.

FAQ
Can I ship on jev-latest?
Pin jev-1.13.0 (the versioned id) after you fit thresholds. jev-latest and the marketing line jev-1.13 can move. Log the response model. Shadow first.
What is the safe default if System One is down? Fail closed on publishing customer-visible copy or a live promo. Do not guess.
Where is the rest of the Ecommerce pack? Start with Ecommerce evaluation and Ecommerce confidence thresholds. Cluster hub: Use cases.
Will Jev personalize the homepage? No. Recs stay in your personalization stack. This pack gates language.
Can we send product images? Not to System One. Transcribe claims. Images are not accepted.
