v3 : le vote par la chaîne Ğ1, côté moteur et serveur
Le bulletin scellé (ld1: + blake2b-256 du bulletin canonique, sel de 128 bits), l'ordre de la chaîne (bloc, puis rang de l'événement : le dernier fait foi), les adresses SS58 comparées par clé (ld-engine, pur). trustin-access : Monnaie libre vote par la chaîne, les groupes gérés sur le serveur ; le droit de vote se lit à la confirmation. Serveur : bulletins en attente, confirmation sur l'indexeur (virement, auteur, identité, membre), identité idty:<index> créée au besoin, tâche de fond toutes les 10 s, expiration à 24 h, vote groupé en une écriture dans les groupes gérés. Migration additive 0006. Sans LD_VOTE_ACCOUNT, le vote par la chaîne est éteint. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

//! The vote, grouped: the whole document, a section or an article in one
|
||||
//! gesture (Yvv, 2026-10-30: « Je peux voter tout d'un coup, ou une section
|
||||
//! entière, ou un article avec son titre, ou séparément »).
|
||||
//!
|
||||
//! - In a **managed group** (essai, Axiom…), the votes are written on the
|
||||
//! server in one transaction, as before: the test group stays easy to try.
|
||||
//! - Where the electorate is the **Ğ1 web of trust** (Monnaie libre), a vote is
|
||||
//! one transaction on the chain, signed by the person's wallet (ADR 0008):
|
||||
//! the server seals a **pending ballot** (`ld_engine::ballot`), the page has
|
||||
//! it signed and sent, and the server **confirms** it by reading the indexer:
|
||||
//! the remark, the transfer of the amount to the vote account in the same
|
||||
//! transaction, the signer's identity and its membership — now. The vote
|
||||
//! counts for the identity `idty:<index>` of the signer, created if need be;
|
||||
//! the session that asked for the ballot sees it as « ton vote ».
|
||||
//! - **The last one stands**, per proposal and per identity, in the order of
|
||||
//! the chain: a ballot confirmed late never overrides a more recent one.
|
||||
//!
|
||||
//! A background task reads the indexer for pending ballots every 10 seconds
|
||||
//! while there are some, lets them expire after 24 hours, and runs the
|
||||
//! adoption pass after each confirmation.
