Rounds

Once started, a pasanaku runs exactly N rounds. Round k pays shuffled participants[k]. Everyone else owes one deposit of round_assets.

Funding: deposit_to_pasanaku

deposit_to_pasanaku(amount, token_id, participant)

Anyone may fund an obligor's deposit. Assets are pulled from msg.sender; credit is recorded for participant.

Guards:

• pool started and not ended
• participant is in the roster
• participant is not the current-round recipient
• participant has not already deposited for this index
• amount == round_assets

Effects:

• _deposited_for_pasanaku[token_id][round_idx][participant] = True
• _successful_obligated_deposits[token_id][participant] += 1
• _pool_escrow[token_id] += amount

Emits PasanakuDeposited with both account (obligor) and payer.

Contributions stay liquid ERC-20 in escrow. They are not converted to vault shares.

Time gate: _MIN_TIME_INTERVAL

assert pasanaku.updated + _MIN_TIME_INTERVAL <= block.timestamp

_MIN_TIME_INTERVAL is 28 days. updated is set at start and on every successful tick. This is a minimum interval between ticks, not a soft calendar hint.

tick

Permissionless. Settles the current round:

1. Require started, not ended, and interval elapsed.
2. _settle_round — sum deposits and cover misses from locked collateral (see Miss and reserve).
3. _accrue_recipient_payout — move payout from _pool_escrow to _pending_payout[token_id][round_idx].
4. Advance updated and index.
5. Emit PasanakuTicked.
6. On the last round (round_idx == participant_count - 1), set ended, call _end_pasanaku, decrement _active_pasanaku_count, emit PasanakuEnded.

tick does not transfer assets to the recipient.

If the vault cannot currently withdraw/redeem the assets needed for a solvent miss conversion, the vault call reverts the whole tick. Callers can retry after liquidity expands; solvent locked collateral is not wiped for a temporary vault limit.

claim_round_payout

claim_round_payout(token_id, round_idx)

Only the designated recipient (participants[round_idx]) may claim. Clears _pending_payout and transfers underlying to the recipient.

The pool may advance while earlier payouts remain unclaimed. Indexers should track pending balances separately from round progress.

Happy-path payout size

With no misses, tick accrues (N - 1) * round_assets. With an underwater misser, the accrued amount is liquid deposits plus whatever assets were recovered from that participant's remaining shares—possibly less than a full round obligation.
