The @computed page replaces a function catalogue the loader does not have with scalo's restricted profile rules. Each value is one CEL expression.

• A @computed expression that fails per record leaves the column empty with no error. One that does not compile is logged and skipped.
• GeoIP, reputation and risk come from the geoip and enrichment config, not from @computed.
• The Python REST API spec, the chaining and cost sections, the UI builder flow and the version history are gone. No such routes or package exist.
• The Rust example uses only the TableTags calls that exist.
• The loader creates no table. Auto-init, engine detection, custom profiles and the v1 migration are gone from the common header page.
• _org_id comes from routing.org_id_field alone, never a column directive.
• Config examples are YAML with default_db dfe and default_table main.
• Operations lists the DFE_LOADER_* env names, the clickhouse.protocol guard and scaling_circuit_open. The added scaling section gives the DFE default: CPU 70% plus the pressure trigger, cleared on slim.
• The transports are Kafka and gRPC. IPv4 is little-endian on the wire. routing.source_to_table has a settings row.
• Dropped contributor notes from types.md, tls.md and operations.md.
