# 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Options considered: moving originals would break historical references; rewriting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.
