// Ledger backfill guard (2026-10-15): the credits wall lagged the PR corpus.
// The CONTRIBUTOR-MAP audit found four merged PRs by authors with no entry at
// all (suhaihui-git #142, Await-d #144, wjurkowlaniec #252, 3219378872 #278)
// and one missing row for warelik (#249 of his fifteen). This pins the backfill
// so the next drift is visible.
//
// The general structural checks live in dashboard-syntax.test.js (README
// representation, docs mirror byte-equality); this file covers the backfill.
