c2patool 0.22.0 fails to validate older media #1413
Description
Sample file:

c2patool 0.19.0 correctly lists the manifest.
c2patool 0.22.0 fails to list the manifest. Instead, it sends an error to stderr:
[2025-09-13T19:59:31Z ERROR c2pa::status_tracker] Validation error: LogItem {
kind: Failure,
label: "self#jumbf=/c2pa/urn:uuid:88eb2bb3-d5f9-4516-9265-b65277b4b861/c2pa.assertions/c2pa.actions.v2",
description: "Actions missing action array",
crate_name: "c2pa",
crate_version: "0.63.0",
file: "sdk/src/claim.rs",
function: "verify_actions",
line: 2006,
err_val: Some(
"ValidationRule(\"No Action array in Actions\")",
),
validation_status: Some(
"assertion.action.malformed",

ingredient_uri: None,
}
Error: validation rule was violated: No Action array in Actions
The expected result:
If the manifest has a problem, it should be in the stdout json's "failure[]" section. It should not abort and dump output to stderr.
This error is not related to the file being a forgery. (I have plenty of non-forgery examples that fail the same way.) The problem is related to only supporting C2PA v2.2 and failing to process anything older.
