Development record

TestConcurrentFailedIngestsOfOneReceiptFileOneIssue (internal/core/capture/auditowed_test.go) failed on a macOS shard with 'could not acquire mint lock within 5s', and its queue entry was dropped with no defect behind it. Four concurrent ingests contend for the intent store's mint lock, whose wait is a fixed 5 seconds (mintLockTimeout in internal/core/intent/create.go), and on a loaded runner a holder can outlast it. The wait is the production default, so a real ingest on a loaded machine can lose the same race.
