davideandClaude Sonnet 5.5	54dbffb552	Credit deposits at deposit_confirmations and verify the round's coins with the quorum before paying (B-82, DEP-03, DEP-04, DEP-09, DEP-12, DEP-14, ELC-17, ELC-27, RND-21, RND-22, RND-25, RND-39, DAT-10, DAT-11, DAT-24, DAT-62, DAT-67, DAT-68, AUD-12, AUD-44, AUD-45, API-30, API-31, API-36, ADR-06, ADR-52) ... A user could bet and then double-spend the 1-conference deposit that funded the bet with a private chain: the bet left the chain but its participant stayed `confirmed`, and the payout failed "insufficient pool UTXOs" for ever with everyone else's money stuck. Coinbase outputs were also credited at 1 confirmation (maturity is 120). Deposits - `round_config.deposit_confirmations` (default 6, 1-100, editable from /admin) is the threshold for a deposit; an output of a platform transaction (any txid of a pending_transactions row, RBF versions included) keeps 1; a coinbase output needs 120, recognised from the raw transaction, which must hash to the txid (`is_coinbase`, cached). `read_deposit_policy` / `classify_new_deposits` run between the read and the write, so no session is open across the lookup. - The quorum must also place the coin deep enough on our own tip (ELC-17). - Confirmed outputs short of their threshold are pending deposits (memory only, replaced at every refresh): shown in `pending_balance_sats` / `has_pending` (also for DEP-13's withdrawal message), never spendable. No scripthash notification announces a maturing deposit, so each new block refreshes only the users that have one, one task per user (DEP-09 now says so). Payout - `_trigger_payout` verifies the round's confirmed participants' bet outputs with the other servers (`verify_pool_outpoints`: strict majority of >= 2 answers per outpoint, a mempool-only coin or a tie gives no verdict) and builds from exactly those outpoints (RND-22), never from whatever else sits at the address. No quorum: `payout_failed`, `pool verification unavailable`, nothing changes. Bets that are gone become `reorged_out`, one `participant_reorged_out` row each, `pool_amount_sats` rewritten (only downward) in the same transaction, and the 70/30 split is computed on what is left. - Winner's own bet gone: nothing is built; `rounds.payout_blocked_at` (Alembic f2c64a8d1e93, with `deposit_confirmations`, plain add_column) is set, `payout_blocked` and the pause with `paused_reason = 'payout_blocked'` are written in one transaction; `POST /admin/resume` clears the mark and the next attempt verifies again. /admin/rounds returns it. - Rounds opened before B-80 (pool = the shared reserve address) keep the old active-server `listunspent` choice, since that address holds no single round's bets. Ambiguities resolved: the winner's row stays `confirmed` while held (AUD-45 says every participant whose bet is gone becomes `reorged_out`, but OPS-30/DAT-68 need the verification to repeat after the resume, which only a `confirmed` row allows); `/`'s deposit hint no longer says "1 confirmation" (7 languages, same keys); guides updated. Tests changed because the spec changed: listener tests that credited height-100 coins at tip 0 now set a tip past every threshold; the payout fixtures seed confirmed participants (the new source of the inputs) instead of an active-server `listunspent`, FakeNetwork answers the verification, and test_round_pool_address asserts the quorum is asked about the round's address. New: thresholds at exactly 6/5, configured value, coinbase at 119/120 and a mismatching or missing raw tx, platform outputs at 1, dust, quorum height, waiting-deposit display and disappearance, block-triggered refresh, resume, verification verdicts, gone bets excluded with the split recomputed, winner gone held and paused, held payouts untouched until the resume, re-verification after it, no quorum, a payout with 1 and with 400 participants against reserve+fee+dust, admin config bounds and migration. Mutation-checked: threshold 1, ignored coinbase, no height bound, no verification and no winner hold each fail tests.

davideandClaude Sonnet 5.5	fd6a91e93d	Give every round its own pool address (B-80, RND-35, DAT-60, DAT-11, REG-14, SEC-08, BET-12, RND-22, WDR-14, SEC-43, API-23, API-36) ... All bets of all rounds paid one address (m/84'/746'/0'/1/0), so its history grew forever, other rounds' money and stray coins mixed with a round's own, and the payout picked from everything it held. - hd.py: derive_pool_key/derive_pool_address(round_id) on branch 2 (m/84'/746'/0'/2/<round_id>); no argument is the reserve address 1/0. derive_round_pool_key checks the key against the address stored on the round, so a payout can never be signed for money its key does not control. - rounds.pool_address (migration 477bddae1a84, existing rounds backfilled with the reserve address since that is where their bets went; add_column, not a batch alter, so the expression indexes stay): written in the transaction that inserts the round, once its id exists. - place_bet pays round.pool_address; the payout reads, signs and takes change at the round's own address; own_address_for and bump_fee's _signing_context follow the round (confirmation poller and reconciler pass round_id). - Withdrawals to any round pool address, the reserve address or fee_address are refused (withdrawal_to_platform_address, 400, all seven languages). - GET /rounds/current and GET /admin/rounds expose pool_address. - RND-22/DAT-11 stay "da implementare" for B-82: the payout still spends every confirmed coin at the round's address, not only the participants' outpoints (participants carry no bet_vout yet). - tests/unit/conftest.py: every test now gets a throwaway master key. Opening a round derives an address, and tests that merely opened a round were silently reading the real key from the local .env. - Existing tests changed because the spec changed: payout fixtures give their round a pool_address; the reconciler's address-cache test uses two payouts of one round (rows of different rounds no longer share an address); own_address_for now takes the round id.
