## TL;DR

Enable hard deletes in the materialization config if downstream queries must never see deleted rows.

## Steps

1. When a source delete does not remove the destination row in an Estuary materialization, check the _meta/op column first: a 'd' value means the delete arrived and was soft-applied because hard deletes are off by default. Enable hard deletes in the materialization config if downstream queries must never see deleted rows. Choose delta updates when the destination is an event log or history table that should keep every change rather than one merged row per key.

## When to use

Use this skill when you run into "Estuary deletes leave rows in the destination unless hard deletes are on".

## When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

## Versions

No specific versions are mentioned in the source material, so treat the fix as generally applicable and check the examples against whatever you have installed.

## Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.
