# Give consumers a defined secret-refresh path

A credential loaded once at startup will not automatically follow rotation. Make refresh behaviour explicit and test it at the connection boundary.

## Identify how the application reads the secret

Determine whether the value is injected at deployment, read at startup or retrieved through a runtime client. Each approach has different update behaviour.

Record the maximum intended age of the cached value and the trigger for refresh. Do not assume changing the secret store updates an environment variable inside an already running process.

Include all consumer types, especially jobs that run infrequently and workers that remain alive for weeks.

## Refresh without exposing the value

Use the supported secret retrieval mechanism and keep credentials out of logs. Record a safe version reference when useful for diagnostics.

```json
{
  "consumer": "invoice-worker-example",
  "secretReference": "database-reader",
  "observedVersion": "version-example-12",
  "lastRefreshOutcome": "succeeded",
  "targetConnectionCheck": "passed"
}
```

This illustrative status describes evidence without containing the secret. Access to even metadata should match operational needs.

Coordinate concurrent refreshes so a burst of failed connections does not make every request independently hammer the secret service. Keep retry and refresh limits bounded.

## Rebuild the target connection deliberately

A refreshed in-memory value may not change existing connection pools or client instances. Define how new connections use the replacement and how old connections are drained under the target's behaviour.

Test a new connection, not only an already authenticated session. Existing connections can conceal a stale credential until they expire.

Handle authentication errors differently from unrelated network failures. Repeatedly refreshing a correct credential will not fix a blocked route.

## Verify the delayed consumer

Pause one test worker through rotation, then resume it. Confirm that it refreshes and performs the intended operation without needing the old credential to remain valid indefinitely.

Run the scheduled job path as well as the main application. A nightly report can be the last undiscovered consumer.

Document whether refresh failure uses a still-valid cached credential, pauses work or fails the request. The appropriate choice depends on the target and security policy, but it should not be an accidental consequence of a library default.
