Correct the hashes left by the branch rewrite (467bbd7 -> 620f20b,
4059cb4 -> ffcbed6), annotate a8cd5e8 and c59e4bf as reachable only
through the 598a7c3 squash, strike the case 33 claims that 4de5b6b
made stale, and re-measure the section 1 table, the gates.md length and
the ADR share at baa2f5d. Add section 12 for the final seven-reviewer
round. Move the record under docs/notes/, alongside the repo's other
closed decision records, and update ADR-0024's pointer to it.
