# agent hyperdrive config pointed at the staging database

## TL;DR

The Hyperdrive config points at the staging database, so production serves staging data (or writes to it). Fix the connection string per environment, verify with a canary query, and make configs environment-scoped. Database pointers are the most dangerous config values.

```text
agent hyperdrive config pointed at the staging database
```

## Steps

1. Confirm which database is actually connected (a canary query with a known marker).
   Expected: The wrong target is proven.

2. Fix the config to the production database string.
   Expected: The pointer is correct.

3. Verify with the canary query again.
   Expected: Production data is served.

4. Assess damage: did writes go to staging, and does staging contain prod writes.
   Expected: The blast radius is known.

5. Scope configs per environment with no shared defaults for database URLs.
   Expected: The mixup cannot recur.

## When to use

- production serves staging data
- the database pointer is configured
- the agent manages configs

## When not to use

- the database is correct (check the data instead)
- staging is intentionally the target (then it is not prod)
- the pointer is right but the data is wrong (different problem)

## Tool compatibility

- workerd
- Hyperdrive

## Variant phrasings

- "hyperdrive staging database"
- "hyperdrive wrong database"
- "config pointed at staging db"

## Why it happens

Database connection strings look alike across environments, and a staging value in a prod config is invisible until someone notices the data is wrong. Writes to the wrong database are the nightmare variant. Environment-scoped config with no shared defaults is the structural fix.

## Edge cases

- the canary query is the only proof; config files lie
- check both directions: prod pointing at staging AND staging pointing at prod
- rotate credentials if prod credentials ever touched staging
