ensure_partition_expr_columns_in_target 🔒

ensure_partition_operand_columns_in_target 🔒

ensure_table_definition_writable 🔒

ensure_table_writable plus the definition guard for system-defined tables: user CREATE, ALTER and RENAME-into are rejected so the canonical schema cannot be squatted or mutated. DROP and TRUNCATE stay allowed — the next INSERT recreates the table canonically, which is also the recovery path if the canonical definition changes across an upgrade.

ensure_table_writable 🔒

Rejects DDL against read-only schemas and computed entity-graph tables.

find_partition_columns 🔒

find_partition_entries 🔒

Parse Partitions into a group of partition entries.

normalize_flow_bool_option 🔒

parse_ddl_options 🔒

parse_partitions

Parse partition statement Partitions into PartitionExpr and partition columns.

parse_partitions_for_logical_validation 🔒

supported_flow_options 🔒

validate_and_collect_partition_columns 🔒

validate_and_normalize_annotations 🔒

CREATE-side annotation validation: one rule source in the table crate, mapped onto this crate’s existing error variants so client-visible codes and messages stay put.

validate_and_normalize_flow_options 🔒

validate_eval_offset 🔒

Validates EVAL OFFSET semantics at the operator boundary: an offset is only legal together with EVAL INTERVAL and must lie in [0, eval_interval). Never modulo-normalized.

validate_json2_columns_append_mode 🔒

verify_alter

Verifies an alter and returns whether it is necessary to perform the alter.
