DataHub Core
Open the catalog
This is our own DataHub Core instance — the same stack anyone gets from
datahub docker quickstart, holding 1,267 entities across eight
platforms. Everything Comgu claims about lineage, ownership and authority is
readable here, in the source rather than in a screenshot.

datahub/datahub, which is a
well-known default and not something to leave facing the internet. The
basic-auth layer in front of it exists so that default is never reachable.
It is not hiding anything from you.
What to look at
Four things, in the order Comgu reads them. Each one changes what a run does.
1 · The authoritative asset
Search for NH-BREW-PRO and open the Shopify catalog dataset.
Its structured property comgu.authority is set to
authoritative. That marker is what makes it the source of
truth — Comgu does not assume it.
2 · The lineage
Open the Lineage tab. Five downstream surfaces project
from that asset, some three hops out. This graph is the blast radius —
Comgu walks it with get_lineage rather than holding its own
list of what to check.
3 · Criticality and ownership
Each downstream asset carries comgu.criticality and
comgu.customer_facing, which set finding severity. Note that
the AI shopping manifest has no owner — Comgu turns that absence
into a finding instead of guessing a recipient.
4 · What a run wrote back
After you approve a remediation in the demo, the affected assets carry
comgu.last_run, comgu.pull_request_url,
comgu.incident_status and a comgu:remediated tag,
plus a Decision document. Every write is read back before it is reported.
comgu.authority and the engine halts rather
than choosing a value. Restore either and the six findings return. Two tests
in the repository assert exactly this.
Simulated assets are labelled
The downstream commerce platforms are simulated — there is no live Merchant
Center account behind this. Every simulated asset is tagged
comgu:simulated-downstream in the catalog you are about to open,
so you can tell them apart without taking our word for it.
