Defined in:

Overview

The core gem has no controller, no routes and no serializer for lookup tables (docs/core-gem-contract.md §4.4) — deliberately, because POST /import is the only path that enforces the guard against editing brackets an audited formula version resolved to. This controller is therefore the only lookup-table authoring surface there is, and it keeps that property by writing exclusively through ImportLookupTable (via PublishLookupTable) rather than touching entries directly.

This matters because a lookup table is not decoration: a variable with source_type: "lookup" cannot evaluate without one.

#edit ⇒ Object

key and scope are not editable. ImportLookupTable keys on [key, scope, owner], so a "rename" would silently create a second table and leave every formula variable still pointing at the old one — which would keep calculating, against brackets the operator believes they just changed. Entries are what an edit changes; a new key is a new table.
