Payload deployment ID does not match the configured key set

Error message

Payload deployment ID does not match the configured key set

What it means

validate_context ensures the PayloadContext's deployment_id matches the deployment id the key set was configured for. Sealed payloads bind to a specific key deployment; a mismatch means the payload was sealed with keys from a different environment/deployment and must not be sealed or unsealed here.

Solutions

1. Compare context.deployment_id with the configured deployment_id string to see which side is wrong
2. Correct the deployment_id configuration (env var/config file) of the service performing seal/unseal
3. Re-seal the payload in the correct deployment if it was genuinely produced elsewhere
4. Confirm payload provenance before re-persisting — mismatched deployment binding is a security signal

fn ensure_deployment_matches(context: &PayloadContext, configured: &str) -> anyhow::Result<()> {
    anyhow::ensure!(
        context.deployment_id == configured,
        "context deployment '{}' != configured '{}'",
        context.deployment_id,
        configured
    );
    Ok(())
}

match unseal(&blob, deployment_id) {
    Ok(tx) => tx,
    Err(e) if e.to_string().contains("deployment ID does not match") => {
        // surface a config/environment alert; refuse processing the payload
    }
    Err(e) => return Err(e),
}

When it happens

Trigger: Calling seal() or unseal() with a PayloadContext whose deployment_id differs from the configured deployment_id — e.g. staging-sealed payload opened with production keys, or an environment variable holding the wrong deployment id.

Common situations: Copy-pasting a sealed payload between staging and production; DEPLOYMENT_ID env var set inconsistently across services; reusing key material from another cluster after an environment rebuild.
