Tableau Next SDM Authoring — Router

Build semantic data models that actually return data, then enrich, query, and visualize them. This skill encodes the failures that produce empty or confidently-wrong dashboards in Tableau Next — building on empty source objects, leaving objects unjoined, inventing field apiNames, summing an ID, inflating a snapshot by its date count — and carries through to enriching, querying, and visualizing the model.

This file is a router. It does two things: assert the one universal precondition (G1), then dispatch your intent to the right task guide. The guardrails that overlap between steps live in exactly one place — references/shared-gates.md (gates G1–G8) — and each task guide opens with the gates it must assert. Read the gate file once; every guide points back to it.
