- block_verification: skip ParentEnvelopeUnknown check when parent is the proto-array anchor. The anchor's `payload_received` is intentionally false per spec (never added to `store.payloads`), but no envelope is expected for it; without this exception the check rejects every post-anchor gloas block. - network tests: disable `engineGetBlobs` in the TestRig harness. Under real crypto the mock EL's blob fetch raced the gossip path, importing via a spawned task that the test didn't await -- leaving `head_root()` unchanged when the assertion ran. The tests are designed to exercise the gossip + data-column path; the engine fetch was incidental. - network tests: relax `data_column_reconstruction_at_deadline` to allow trailing duplicate reconstruction work items. The reprocess queue removes its dedup entry on dispatch, so a column processed during an in-flight reconstruction can dispatch a second one. The second is a no-op via `reconstruction_started`, so accept >= 1 trailing event.
