ERC-1155 membership

At start, every participant receives one soulbound ERC-1155 membership receipt for the pool's token_id. The token is a membership signal and metadata hook—not transferable collateral.

Mint

_mint_membership_token writes directly into the snekmate ERC-1155 module storage:

• total_supply[token_id] += 1
• balanceOf[owner][token_id] += 1
• emits TransferSingle from the zero address

_TOKEN_AMOUNT is always 1.

Soulbound surface

These entry points always revert with pasanaku: pasanakus are soul-bounded tokens:

• safeTransferFrom
• safeBatchTransferFrom
• setApprovalForAll

isApprovedForAll always returns false.

Exported module helpers that remain available include supportsInterface, balanceOfBatch, exists, and total_supply, plus the local balanceOf view.

uri states

uri(token_id) selects a fixed IPFS CID from lifecycle state:

State	Condition
Not created	token_id >= _counter
Ended	ended != 0
Ongoing	started != 0
Stale	pending and created + stale_time <= now
Pending	otherwise

Constants used in tests (URI_NOT_CREATED, URI_ENDED, URI_ONGOING, URI_STALE, URI_PENDING) match these branches.

Ownership modules

The contract initializes snekmate ownable + ownable_2step and re-exports:

• owner, pending_owner
• transfer_ownership, accept_ownership, renounce_ownership

Membership minting is not gated by ownership; it runs inside _start_pasanaku.
