One-time review ruled 2026-07-19 (utterance: "Tags as proposed + D-122
amendment"): D-121..D-125 [ARCH], D-126..D-129 [OPS], D-130 [ARCH] (new
entries ARCH by construction). Register head gains the GA-R3 class-tag
convention block. D-129's ARCH fragment (Roosevelt metal-edge plugin
transfer profile) split per A1 into a dated AMENDMENT on D-122, the
governing site/edge-shape decision -- governing copy there, D-129 text
retained as history; its four OPEN sub-decisions unaffected. ledger-scan
re-verified: statuses + next-free counters unchanged (D next-free 131).

Revert: git revert this commit.
