feat(emit): fail-fast guard on status-index integrity - #101
Merged
Conversation
Defense in depth against the class of bug that shipped a "revoked" badge. Before any signing/deploy, validate every active record's status_index: integer >= 0, distinct across members (no shared status bit), and absent from the revocation ledger (no active member on a burned index). On violation the build fails loudly instead of silently publishing broken data. This catches what the sequential next-index fix cannot: two near-simultaneous inscriptions that computed the same index before either merged. Pure logic in lib/member-indices.mjs with tests (incl. the exact blafourcade-on-revoked case).

@jdm-web (#106) et @tkman59 (#108) ont reçu le même status_index (3) : certification-pr.yml le calcule à l'ouverture de PR en scannant main, sans tenir compte des PR d'inscription encore ouvertes. Les deux issues traitées avant que l'une des deux merge ont donc lu le même main. Le fail-fast (#101) a correctement bloqué le déploiement au merge de tkman59, empêchant aussi templth (#110) de publier — directory.json reste figé à 2 membres alors que 4 sont enregistrés. - data: réassigne @tkman59 à l'index 5 (libre après templth=4) - ci: le calcul d'index scanne aussi les PR certif/* ouvertes, et le workflow est sérialisé (groupe de concurrency partagé) pour que chaque run voie la réservation du précédent avant de calculer la sienne
