Source of truth

Question	What answers it
Which orders exist	Durable Dogecoin-native SQLite listings, revisions, funded offers, reservations, action requests, funding fences, broadcast lineage, history, and settlement observations
Who owns the asset	Protocol-specific authoritative checkpoint ownership and exact outpoint proof corroborated by Dogecoin Core and, for TAP-DOGE, the pinned immutable TAP reader
Whether a trade settled	Exact Dogecoin raw transaction templates, wallet-authorized permitted input signatures, Core validation and broadcast, chain confirmation, protocol checkpoint convergence, and rollback-safe reconciliation
What the protocol state is	Configured pinned Dogecoin TAP reader and Dogecoin Core

Indexer

Primary index

Configured pinned Dogecoin TAP reader and Dogecoin Core

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 execution-authenticated readiness probe, a complete authoritative checkpoint, Core-verified funding, exact 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 the exact authority checkpoint and an execution-authenticated readiness observation; deployment readiness must enforce its 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 Dogecoin transaction confirmation and the expected protocol-state transition in a later authoritative checkpoint.
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, 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.
