Source of truth

Question	What answers it
Which orders exist	Durable index-unat SQLite listings, revisions, funded offers, reservations, action requests, funding fences, broadcast lineage, history, and settlement observations
Who owns the asset	Exact live UNAT mint inscription, authoritative membership, Ord location, Bitcoin prevout and outspend, and complete 29-protocol output inventory agreement
Whether a trade settled	Exact PSBT templates, wallet-authorized input signatures, Bitcoin Core preflight and broadcast, chain confirmation, authoritative buyer-owned UNAT mint location, and rollback-safe reconciliation
What the protocol state is	Configured index-unat executable Marketplace authority

Indexer

Primary index

Configured index-unat executable Marketplace authority

Fallbacks

None. If the primary index cannot be read, this protocol has nothing to fall back to and the page says the read failed.

What a mutation must prove

Execution requires distinct read and execution credentials, a fresh UNAT readiness checkpoint, exact authoritative mint membership, complete inventory, clean funding, immutable economics, and protocol-native post-sign validation.

Freshness, confirmation, and reorg policy

Policy	Value	What the registry states
Freshness enforced	No	Every mutation is bound to stable UNAT, Ord, Bitcoin Core, and complete-inventory checkpoints; deployment readiness must enforce the configured checkpoint age and lag limits.
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	Settlement requires the exact confirmed Bitcoin transaction and the authoritative UNAT mint indexed at a buyer-owned output at stable checkpoints.
Settlement confirmations	1	A trade is recorded as settled after 1 confirmation.
Automatic reorg reconciliation	Yes	The authority appends reorg observations, reopens or invalidates affected orders deterministically, and preserves funding, broadcast, settlement, and replacement lineage.

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.
