Source of truth

Question	What answers it
Which orders exist	StampDEX SRC-20 order book
Who owns the asset	StampDEX one-time action challenge, seller listing PSBT, and indexed SRC-20 collateral checks
Whether a trade settled	StampDEX fill/confirm endpoints plus wallet Bitcoin broadcast
What the protocol state is	StampDEX

Indexer

Primary index

StampDEX

Fallbacks

• Stampchain activity
• OpenStamp mint/deploy reference data

What a mutation must prove

Universe allowlists and validates the exact proxy route/body/challenge headers; StampDEX rechecks indexed collateral before fill. 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 the StampDEX fill workflow.
Settlement confirmations	not set	No settlement depth applies, because no supported action reaches settlement.
Automatic reorg reconciliation	No	Universe retains broadcast receipts but delegates chain reconciliation to StampDEX.

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.
