Object forwarding

Toggle: enabledChecks.forward · Fix: autofix.forward

Finds object literals forwarding at least three properties from one source, such as userId: input.userId. A safe fix removes exact redundant properties after an existing spread. Whole-object replacement and projections remain advisory.

“Forwarding” is syntactic repetition, not proof two objects have the same contract. A “projection” intentionally selects a subset. Keep explicit projections at persistence, authorization, redaction, schema, versioning, and API boundaries. Common mutation names such as insert, update, upsert, set, and assign are ignored.

Before — the explicit value repeats the same source property after the spread:

sendUser({ ...input, userId: input.userId });

After — remove only the exact redundant property:

sendUser({ ...input });
