+#     DataElement represents BusinessConcept
+#     Same relation -- "this logical artefact is the data-side counterpart of
+#     that business notion" -- at two levels of detail.
+#     A Data Element reaches business meaning by EXACTLY ONE of two routes:
+#       dimensional -> represents a BusinessConcept
+#       measure     -> is computedBy a Metric, which measures the Concept
+#     Never both, never neither. Enforced by sh:xone.
+#
+#  C. STEWARDSHIP DECLARED ONCE, INHERITED EVERYWHERE
+#     monitoredBy sits on BusinessObject only (plus DataProduct, which
+#     spans several Business Objects and cannot inherit). Data Objects and
+#     Data Elements inherit through represents / hasElement. Declaring a
+#     steward at several levels means two answers to "who watches this
+#     column". BusinessObject therefore STAYS in the Ownership layer: it is
+#     the single anchor of accountability, which is what that layer is for.
+#     owningDomain is the exception: inherited by default, but re-declarable
+#     on a Data Element, because OW-002 attributes an element to the domain
+#     that defines its rule. A DE that re-declares is a borrowed element --
+#     a signal to check against its represents, not an anomaly.
+#
+#  D. BUSINESS MEANING LIVES IN ONE PLACE
+#     hasBusinessDefinition is removed from BusinessObject. Meaning belongs to
+#     the BusinessConcept; a Business Object gets its meaning through
+#     aboutConcept. Two definitions for one notion are two definitions free to
+#     diverge.
+#
+#  E. GRAIN MOVED OFF THE METRIC
+#     hasGrainDimension (Metric -> DataObject) and hasGranularity are gone.
+#     Grain is a property of a DATASET, not of a calculation rule: a Metric
+#     has no rows. hasGrainElement (DataObject -> DataElement) replaces them
+#     and is CHECKABLE against the harvested PrimaryKey. A Metric's grain
+#     becomes derivable from where it lands.
+#
+#  F. DELIVERY IS ITS OWN LAYER
+#     DataProduct / DataInterface / DataContract answer "what do we promise,
+#     to whom, until when" -- a different question from "how is it
+#     structured". DataAsset is renamed DataInterface and redefined as the
+#     CHANNEL through which a consumer actually gets data (a Snowflake share
+#     or grant, a file extract, an API), which is verifiable, rather than
+#     "directly consumable by a business user", which was a judgement call and
+#     produced zero instances in a year.
+#     Every Data Product is operated by exactly one Sub-Domain and has exactly
+#     one Product Owner: it is a consumable, and there must be no ambiguity
+#     about who runs it.
+#
+#  G. realizesMetric KEPT AS A TRANSITIONAL CONTROL
+#     Declared, required on certified BI fields, and that is all. No rule is
+#     written against the lineage chain: making the assertion conditional on
+#     intermediate mappings existing would create confusion and discourage
+#     people from filling it in at all.
+#
+#  Deprecated terms are kept, never deleted (LC-002): existing assertions keep
+#  classifying, and the migration can be staged.

+SODH arbitration - composedOf -> aboutConcept + usesConcept
+============================================================
+Second half of the v1.0 -> v1.1 migration. migrate_instances_v1_1.py did the
+mechanical renames and deliberately stopped here, because everything below is a
+judgement someone had to make.
+
+USAGE

+
+WHAT WAS ARBITRATED (Bastien, 2026-07-27)
+-----------------------------------------
+The v0.6 padding is what made this necessary: four Business Objects belonging
+to other domains -- Product Structure, Customer & Outlet, Currency, Calendar --
+were all declared composedOf the same three Sell Out concepts, because BR-004
+demanded three and there were none to give. The subject rule replaces that
+minimum: exactly one subject, and if it cannot be named the object is not
+scoped.
+
+  1. Distribution -> Retail Distribution.
+     "Distribution" is too generic to survive contact with other domains, and
+     it is NOT a kind of sell out: sell out counts units sold, distribution
+     measures product presence in store. Retail Distribution follows panel
+     vocabulary (Nielsen/Circana), under which Numeric and Weighted
+     Distribution are the metrics.
+
+  2. Sell Out Baseline becomes a concept in its own right, not a flavour of
+     Sell Out: modelled non-promoted volume is a different notion from
+     observed volume.
+
+  3. Customer & Outlet splits into two Business Objects, and Currency &
+     Exchange Rates likewise. An object named "X & Y" has no single subject,
+     which is precisely what the rule is meant to surface. The split is
+     PROPOSED here; DD-04 and DD-16 own the decision.
+
+  4. Six concepts belonging to other domains are created with a DRAFT
+     definition and arbitrationStatus TO_ARBITRATE. A draft to correct beats a
+     blank to fill, and OW-007 blocks publication until the owning domain has
+     ratified. These definitions are the DGO's proposal, not DD-04/10/16/21's
+     word.
+
+NOT DONE HERE
+    hasGranularity on Metrics still needs re-expressing as hasGrainElement on
+    Data Objects, and the BR-013 alignment (10 mother metrics, computedBy)
+    is a separate migration. Until that lands, every Data Element will fail
+    the XOR-of-meaning shape -- which is the correct, informative result.

+PR Data Meta Model - SHACL validation runner
+=============================================
+The automated gate behind rule DQ-011. Validates an instance graph against the
+executable rulebook (SHACL shapes), with the T-Box supplying subclass
+entailment.
+
+USAGE
+    python3 scripts/run_shacl_validation.py                    # all instances
+    python3 scripts/run_shacl_validation.py instances/sodh.ttl # one file
+    python3 scripts/run_shacl_validation.py --quiet            # CI mode
+
+Paths resolve against the repository root (the parent of scripts/), so the
+script runs correctly from anywhere.
+
+EXIT CODES
+    0  conforms, no blocking violation   -> eligible for PUBLISHED
+    1  violations found                  -> stays DRAFT / UNDER_REVIEW
+    2  the run itself is not trustworthy -> a green result would be meaningless
+
+Exit code 2 is the important one. A validation gate that passes because no
+shape matched anything is worse than one that fails: it reports success while
+checking nothing. The pre-flight below refuses to let that happen.
+

-#  PR Data Meta Model - SHACL Shapes v0.1.1
-#  Executable encoding of BLOCKING (sh:Violation) & MAJOR (sh:Warning) rules.
-#  FIX v0.1.1 (2026-07-23): NR-002 uniqueness query now restricts ?cls to
-#  LEAF classes (via FILTER ... IN) so that objects of different layers that
-#  share a name (e.g. Sub-Domain "Sell Out" vs Concept "Sell Out") are NOT
-#  reported as duplicates. Rule stays "unique WITHIN its class".
-#  Run: python run_shacl_validation.py SODH_data.ttl pr_metamodel_shapes_v0.1.ttl pr_metamodel_v0.9.ttl
+#  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 harvested half of the graph that would fail on
+#     every one of ~50 000 Snowflake columns. Curated and Observed 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
