-#################################################################
-#  PR DATA META MODEL - SHACL SHAPES v0.2
-#  Aligned with T-Box v1.1 and Rulebook v0.3.x
-#
-#  WHAT CHANGED vs v0.1.1
-#  ----------------------
-#  1. SPLIT BY PROVENANCE. v0.1.1 targeted pr:MetaModelObject and demanded an
-#     identifier, a name, an owner, an owning domain, a status and a version on
-#     everything. Applied to the captured half of the graph that would fail on
-#     every one of ~50 000 Snowflake columns. Defined and Captured objects now
-#     have separate shapes with separate expectations.
-#
-#  2. SCOPE FOR THE UNIFIED RELATIONS. belongsTo and represents deliberately
-#     carry no rdfs:domain/range in the T-Box, because each serves two classes
-#     with different targets. The scope lives here instead, per class.
-#
-#  3. MEANING IS AN XOR, NOT A CHECKLIST. A Data Element reaches business
-#     meaning by exactly one route. sh:xone rejects both zero routes and two.
-#
-#  4. NO COVERAGE RULES. Nothing here requires a Business Concept to be
-#     realized, or a Business Object to hold N concepts. That was BR-004, and
-#     encoding a coverage expectation as a blocking constraint does not produce
-#     coverage -- it produces padding. Coverage is a dashboard metric.
-#
-#  5. PORTABLE REGEX. No lookbehind: sh:pattern is normatively XPath 2.0
-#     regex, which does not support it. Written as sh:not [ sh:pattern ... ].
-#
-#  SEVERITY MAPPING
-#     sh:Violation -> BLOCKING, cannot reach PUBLISHED, fails CI (DQ-011)
-#     sh:Warning   -> MAJOR, must be reviewed, does not block
-#     sh:Info      -> GUIDELINE, informational
