/**
* cry01_attestation.php — STUB INTERFACES ONLY. Nothing in this file is
* implemented. Every function returns a "not implemented" placeholder.
*
* This file documents the planned shape of two related future features:
*
* 1. ATTESTATION — W3C Verifiable Credentials + OpenTimestamps proofs for
* records produced by cry01 (balance lookups, ballot definitions,
* ballot outcomes). Per CRY01-SPEC.md, this is part of the shared
* credential infrastructure that poll01 and future addons depend on.
*
* 2. BALLOT TALLYING — the wallet-to-wallet voting model described below.
* This is the END GOAL that g1wallet, cry01, and poll01 are jointly
* building toward. Nothing here is implemented; this file exists so
* the eventual implementation has an interface to fill in rather than
* bolting tallying logic onto whatever shape cry01_chain.php happens
* to have at the time.
*
* ============================================================================
* THE BALLOT MODEL (as designed, 2026-06-12)
* ============================================================================
*
* For a given poll (e.g. "Should the association approve budget item X?"):
*
* - Two Ğ1 wallets are provisioned for the poll: a YES wallet and a NO
* wallet. Who controls these keys and how they are provisioned is NOT
* YET DECIDED — see OPEN QUESTIONS below.
*
* - Each eligible voter (a SASE-verified participant with a Ğ1 wallet) may
* send AT MOST ONE TOKEN to either the YES or NO wallet during the
* voting period. The transaction itself — wallet-to-wallet, with a
* block timestamp — IS the vote and IS the timestamp. No separate OTS
* step is needed for individual votes.
*
* - TALLY RULE: count only the FIRST token received from each eligible
* voter's wallet (by block order). Any additional tokens from the same
* wallet, to either YES or NO, are ignored for tallying purposes. This
* is an APPLICATION-LAYER rule — nothing on-chain prevents a wallet from
* sending multiple tokens; cry01/poll01 must enforce "first token only"
* when counting.
*
* - ABSTENTION: (number of eligible voters) - (yes_count + no_count) =
* abstentions. No "spoiled ballot" state exists — a voter either sent
* exactly one token to one wallet, or did not vote.
*
* - AFTER THE VOTE: all tokens in both YES and NO wallets are sent to the
* association's wallet, to be used as the homeowners subsequently
* decide. This transfer is itself a public, timestamped on-chain event
* — closing the books on the poll.
*
* - PUBLIC BALLOT BY DESIGN: every vote is a public on-chain transaction,
* permanently linking a voter's wallet address to their choice. This is
* intentional — Illinois law and federal law do not require HOA votes
* to be secret, and public attribution provides verifiability without
* requiring trust in the board's counting.
*
* ============================================================================
* OPEN QUESTIONS (not blockers — design space the interfaces below must
* accommodate, not resolve)
* ============================================================================
*
* - YES/NO wallet provisioning: who creates these wallets, who holds the
* keys during the voting period, how is the post-vote transfer to the
* association wallet authorized/triggered (manual operator action vs.
* some automated/multisig mechanism)?
*
* - Voter eligibility registry: cry01_get_eligible_voters() needs a source
* of truth for "which Ğ1 account IDs belong to SASE-verified members of
* this association, as of the poll's start date". This likely overlaps
* with the g1wallet pubkey-registration flow (cry01's signal form
* already has a data-g1wallet-target="pubkey" field) but the
* association-membership-at-a-point-in-time registry does not exist yet.
*
* - Participation barrier: sending a token requires the voter to HOLD at
* least one Ğ1 and pay any associated transaction cost. Whether this is
* a deliberate "skin in the game" feature or an unintended barrier for
* participants who hold zero Ğ1 is a POLICY decision, not addressed
* here. cry01_get_eligible_voters() and cry01_tally_ballot() should not
* assume either answer — e.g. don't assume "no token sent" always means
* "chose not to vote" vs. "could not afford to vote", though the
* externally-visible RESULT (abstention) is the same either way.
*
* ============================================================================
* THE TRANSACTION-HISTORY DEPENDENCY
* ============================================================================
*
* cry01_get_wallet_transactions() is the hard dependency underlying
* cry01_tally_ballot(). Per docs/DUNITER-RPC-FINDINGS.md §4.3, NEITHER
* current Duniter node (light mirror or full-fast-sync) can answer "what
* transactions has account X sent/received" — both use
* --state-pruning 256, which only retains recent state, not transaction
* history. Tallying a ballot requires scanning all transactions to the
* YES/NO wallets over the poll's duration, which requires either:
*
* - an archive node (--state-pruning archive), much larger disk footprint
* than either current node, or
* - a separate indexer (e.g. a Subsquid/Squid instance, as referenced in
* Duniter's own public-RPC documentation) that processes blocks as they
* arrive and maintains a queryable transaction database
*
* This is a SEPARATE INFRASTRUCTURE PROJECT from anything in cry01_chain.php
* or cry01_substrate.php. The interface below assumes it exists; building it
* is future work.
