A.16.0:4.0a - Identify the account and its expression

1. Apply the history threshold. Keep a local A.16 move note when it answers the receiving question. Use the fuller account only when branch, loss, lineage or an actual responsibility history changes a later use.
2. Identify the account’s subject. For a source-centred history, name the exact source episteme as EntityOfConcern and state the relevant edition and relation claims in the account’s ClaimGraph. For a relation-centred account, identify the independently obtaining relation it concerns. A negative or unresolved lineage claim remains about an independently identified source or other subject; it creates no relation occurrence.
3. Recover the relevant history claims. Distinguish the source editions, position claims, actual lineage, moves, losses and next use needed here. Use their direct rules below. State an unknown link or a supported no-successor result explicitly rather than inventing continuity.
4. Choose an adequate expression. The LanguageStateMoveTrajectory form can express that account. Under E.24.PUB, publication form is a relation-defined participant meaning over an independently identified entity; using the form admits no subtype or second account individual. Recover its expression relation, carrier and any availability occurrence only when the receiving claim needs those distinctions.
5. Return the history needed by the next use. Make the relevant branch, loss, limit or responsibility fact recoverable. Stop when that use is supported; a further account of the account’s own history is needed only if another receiving question requires it.

The filled account has its own C.2.1 identity. Described source editions, position claims, loss notes and relation facts contribute to its content; they are not additional identity fields. A source-history event and the account acquiring knowledge of that event are different changes. Changed account content identifies another episteme, with edition continuity asserted only when its own relation obtains.

Several unrelated sources displayed in one table do not become one history individual. A common carrier or form can support separately grounded accounts and expression claims. Each claimed E.24.PUB publication occurrence still concerns one exact selected episteme edition and one bounded use. Publishing a history account is also distinct from publishing each source edition that it describes.
