An EC PUT that\ndid not complete its commit phase leaves such fragments. With the parent\nchange, a GET for that object answers 503, but a HEAD still answers 404,\nbecause HEAD does not use the EC collection code. The probe test\ntest_ec_missing_all_durable_fragments fails with 503 !\u003d 404.\n\nOnly durable evidence proves that the object exists. The fallback now\nanswers 503 in two cases: a durable bucket has fewer than ec_ndata\nresponses, or a backend reported a durable timestamp but the proxy\nreceived no fragment for it. Non-durable fragments without such\nevidence reach the existing not-found fallback, so GET and HEAD both\nanswer 404.\n\nA 404 from an object server carries X-Backend-Timestamp but no data\ntimestamp.
