Source of truth

Question	What answers it
Which orders exist	StampDEX Counterparty dispenser order book
Who owns the asset	StampDEX/Counterparty indexer-backed compose validation plus wallet PSBT signatures
Whether a trade settled	StampDEX Counterparty dispense composition and Bitcoin broadcast
What the protocol state is	StampDEX and Stampchain

Indexer

Primary index

StampDEX and Stampchain

Fallbacks

• OpenStamp for reference metadata

What a mutation must prove

Universe allowlists and validates the exact proxy route/body; StampDEX/Counterparty validates dispenser state. Universe does not compare provider and Bitcoin tips.

Freshness, confirmation, and reorg policy

Policy	Value	What the registry states
Freshness enforced	No	Universe does not enforce a StampDEX-versus-chain lag threshold.
Maximum index lag	not set	No numeric block-lag ceiling is configured for this protocol.
Maximum observation age	not set	No maximum age is configured for an observation used by a mutation.
Listing confirmations	not set	Confirmation policy is delegated to StampDEX/Counterparty.
Settlement confirmations	not set	No settlement depth applies, because no supported action reaches settlement.
Automatic reorg reconciliation	No	Universe relies on StampDEX/Counterparty state and has no local rollback worker.

Where else this protocol appears

The Bitcoin Universe registry records actions per product surface. Core is the main surface. The others are named here because a reader who cannot do something in Core may be able to do it in a sibling product.
