Per-claim attribution moves to a markdown footnote keyed to a sources[].id
(SPEC §4.2 :224-225, §5.1 :347-360), and the shipped acme_retail bundle carries
it inside a schema table. Our supersession row stated the destination and not
the mechanism, so a consumer following it would migrate the list and drop the
claim->source binding.
Measurable at the pinned commit the whole time; surfaced by Google's launch post
2026-07-27. U1-U7 measured frontmatter in all four reference bundles and walked
past the bodies. V-A1's discharge is narrowed rather than reworded: the pin
holds, the reading's depth did not.
Consequence outside the doc: the v0.2 exposure report sent to the wiki states
the incomplete half under the heading that exists to size their cost. Correction
owed, same class as A-E3.
