-- 0pt Iceberg write-path ownership: field-level gap closure pass

-- 004_iceberg_write_boundary.sql shipped opt_dataset_iceberg_mappings without

-- literally (0pt.dataset_iceberg_mapping.schema.v1: dataset_id,
|
|
-- iceberg_table_id, namespace_id, mapped_at, mapped_by), and this session
|

-- also live-verified (real HTTP calls against api.st0re.siax.io) that

-- ST0RE's namespace registry (/v1/st0re/lakehouse/namespaces) returns a real

-- namespaceId distinct from the bare namespace name -- so namespace_id is a
|
|
-- genuine reference, not a renamed duplicate of the existing `namespace`
|
|
-- column. Both new columns are nullable additive columns; no data migration
|
|
-- needed since 004 has not been applied to a live database by any session
|
