2. Common Header

[SPEC] Every declaration file begins with the same two fields. A parser reads them first and only then decides how to interpret the rest of the document.

YAML

kind: tck          # or: test
syntax: v1-alpha

Field	R/O	Values	Notes
kind	R	tck | test	Fixed. Used in every declaration file so the parser knows how to read it.
syntax	R	v1-alpha	Engine/Test Lab library syntax version, i.e. which technical capabilities are available. Should not change often.

⚠️ Known inconsistency [PROP-P6]. The index.yaml screenshot on slide 17 shows testlab: v1-alpha and a top-level namespace: ccm-v0.0.1; the field specification on slide 18 shows syntax: v1-alpha and no manifest-level namespace. This document treats slide 18 as normative: the key is syntax: everywhere, and namespace: appears only in test files. Confirm before freezing v1-alpha.
