Run a focused build¶

Use a focused build when you need to execute one governed layer and all inputs required to make that result self-consistent.

Load the environment¶

set -a
source .env
set +a

Preview the selector¶

For example, preview Layer3 and its upstream dependencies:

uv run dbt ls --select +tag:layer3 --output name

The leading + means “include ancestors.” Review the list before executing it.

Build the selected slice¶

Choose the slice that matches the work:

uv run dbt build --select +tag:layer1
uv run dbt build --select +tag:priva_map
uv run dbt build --select "+tag:layer2 +tag:quarantine"
uv run dbt build --select +tag:layer3
uv run dbt build --select +tag:case_views

Run one command, not the whole block. dbt build executes the selected resources and their tests; it is preferred here over a model-only dbt run.

Verify the result¶

Preview the output you changed with dbt show. For example:

uv run dbt show --inline '
select customer_key, customer_segment, is_active
from {{ ref("dim_customer") }}
' --limit 10

Check the row shape and values that matter to your change. Do not treat a successful command as a substitute for inspecting the result.

If the change affects grants, masks, or case access, also follow Reconcile access controls.

Consult Tests and selectors for the full selector contract.
