Which orders exist	Local Ordex journal with signed PSBT digest and source evidence
Who owns the asset	Local Bitcoin Core gettxout plus local ord claim validation
Whether a trade settled	Caller-provided final transaction preflight only

What a mutation must prove

Build/publish validates live UTXO and ord claim; no persistent node/indexer lag metric is enforced.

Freshness, confirmation, and reorg policy

Policy	Value	What the registry states
Freshness enforced	No	Orders can be manually revalidated; there is no automatic lag threshold or reconciliation cadence.
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	Ordex never broadcasts or records a completed settlement.
Settlement confirmations	not set	No settlement depth applies, because no supported action reaches settlement.
Automatic reorg reconciliation	No	Manual revalidation can change actionability; no automatic reorg state transition exists.

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.
