## Fix
1. ) with its own complete set of bindings: D1 databases, KV namespaces, R2 buckets, queues, DO namespaces.
   Expected: this specific failure stops.
2. Dates 2026-08-04 and later enable.
   Expected: this specific failure stops.
3. Make that true in the config, not just in policy.
   Expected: this specific failure stops.

## Details
# Workflow: multi-environment Workers ## 1. Environment matrix Define each environment ( `dev` , `staging` , `production` The production database binding must not exist in any other environment's config. ## 2. Secrets per environment `wrangler secret put --env [name]` Declare required secrets in config so deploys fail fast when one is missing. Audit: list secrets per environment quarterly; stale secrets are a breach surface. ## 3. `staging.example.com/*` vs `example.com/*` . A staging deploy without its own route either does not serve or, worse, serves on an unexpected hostname. ## 4. Compatibility dates pinned Pin the same compatibility date across environments. `nodejs_compat` behavior by default: a date difference between staging and production is a behavior difference. ## 5. Promotion flow Local dev -> preview URL (PR) -> staging deploy + smoke tests -> production deploy + tail. Smoke tests touch every binding (write and read), not just the HTTP surface. ## Checklist - No shared bindings between staging and production, ever. - Routes, secrets, and dates verified per environment before each promotion. - Staging data is disposable; production data is not.

## When to use
You hit exactly this: Workflow: dev, staging, and production Workers without cross-talk in Workflow.

## When not to use
A different error, or the same symptom in a different tool. This page only covers the failure above.

## Compatibility
Workflow.

## Edge cases
- for each environment.
- Routes per environment Each environment needs its own routes or custom domains:.
