   pepe rule: if not on L1, it didn't happen

01 · Doctrine

• If it is not in L1 state or events, it is not canon.
• No strings in storage — only bytes32 contenthashes.
• No AMM. No launcher. Pairs are pointers, not products.
• One specimen per token address. Parent edge optional.

05 · Anti-spam

Permissionless mint without friction fills the shelf with noise. Draft gate:

1. Bond — posted at register; returned if unchallenged after N days.
2. Liquidity floor — primary pair must clear a minimum at register time.
3. Challenge window — contested contenthash / parent / template can be disputed; winner written back on L1.

06 · Cost posture

Expect roughly 200–400k gas per register. Pack structs. Fat events for indexers; skinny SSTORE. Multicall for curator backfill of historical specimens. Immutable v1 preferred; if upgradeable, UUPS + timelock.

07 · Ship ladder

1. Specimen NFT + one-per-token + contenthash + parentId
2. Curator-funded backfill of the historical set (so the shelf isn’t empty)
3. Permissionless register with bond + liquidity floor
4. Read-only explorer (state + logs only)
5. Caught proofs, if collection gameplay is wanted

  [1 NFT] → [2 backfill] → [3 open mint]
