+# Canon federation research provenance
+
+Status: closed provenance distribution. Disposition: observe. Native workplan:
+INFO-WP-0024; project task CFED-WP-0001-T07. These are historical research inputs,
+not newly adopted definitions or evidence that external sources are current.
+
+## Context and decision
+
+Accepted ADR-006 assigns concept destinations and the user authorized continuing
+the migration. T07 routes already-completed research; it does not rerun research
+or open a new domain-concept adoption decision. Preserve immutable source copies
+and route shared material through model-specific indexes and exact fragments.
+Source repository: commerce-canon, commit `8a07292dd78d094151f165d3ac1dfc7512114308`.
+
+Options considered: moving originals would break historical references; rewriting
+old assertions would destroy provenance; copying without destination indexes would
+hide the split. The chosen layout retains originals and copies frozen snapshots,
+with SHA-256 records and destination-specific reading views.
+
+## Scope and consequences
+
+45 source files are present here, including their complete context.
+[distribution.json](distribution.json) records source paths, hashes, applicable
+models and exact fragment line ranges. [source-summary](source-summary.md) lists
+the corpus areas. [comparison-matrix](comparison-matrix.md) applies the existing
+ownership ledger. [mappings.yaml](mappings.yaml) records the authoritative donor
+term destinations; it is a migration mapping, not a new external-vocabulary model.
+
+Views under views/ partition the shared terminology rows, conflict sections and
+scenario sections by destination interest. Each fragment is verbatim, with its
+source locator and a warning that current canon takes precedence. Model indexes
+link full source notes without removing context. A shared source copy does not
+create a second concept owner. Source files are never runtime normative artifacts.
+
+## Review trigger
+
+A revised external source is a new intake; do not edit these snapshots. Any new
+concept or behavior proposed from the corpus requires its own review. Historical
+open questions remain historical; current unresolved work is linked in
+[open-questions.md](open-questions.md). No new domain definition is adopted here.
