Validation & release

Review model agreement, mixed-system composition and physical outcomes before release.

Concept artwork · Detect the mismatch before release.

SYSTEMS / IN DETAIL

Test the places where representations disagree.

A diagram can be internally consistent while the installation behaves differently. Validation should cross the boundaries between authored intent, generated configuration, runtime entities and physical observations.

ENGINEERING / FOLLOW THE FLOW

CONCEPTUAL MECHANISM 01 / 04

Boundary	Responsibility	Engineering consideration
Stale state	A previous observation survives an outage	Show availability and freshness; do not imply that the last value is current.
Partial publication	Only part of a revision reaches a consumer	Exercise failure and recovery around promotion and acknowledgement.
Mixed systems	One device family succeeds while another fails	Test compositions and failure isolation, not only individual happy paths.

What belongs in release evidence?

Record the scenario, configuration revision, expected result, observation and disposition of failures. A screenshot is useful evidence of a visible state; it does not prove all transports, permissions or physical outcomes. Review software acceptance separately from site commissioning.

03 / VALIDATION & RELEASE

Test the agreement,
not just the request.

Model review

Verify room binding, stable identity, owning tenant and the scope of each override before publication.

Composition review

Exercise KNX-only, cloud-only and mixed project paths. Do not turn an empty protocol branch into an invalid home.

Outcome review

Compare authored intent with installed state. A successful request is not proof of physical actuation or fresh observation.

Harness structures our internal development progression through initiation, design, contract, Alpha, Beta and release gates. Project configuration and software release remain separate responsibilities.
