Close Posting Lineage

A month-end close lineage verdict over declared entries: GL coding entries and accrual entries in (lineage key, GL account, amount, optional source document digest, optional traces_to references), linkage structure out (accruals that resolve to a declared coding entry, accruals with no reference, every reference naming a key nothing declares, coding entries nothing traces to, coding entries with no source digest, repeated lineage keys, overall CLOSE_READY, GAPS_FOUND or INDETERMINATE). Four stages in one pure compute() per CLOSE-COMMAND-CENTER-BUILD-SPEC-2026-09-23.md section D2: intake with fail-closed shape validation, lineage key uniqueness, per accrual linkage classification, coding side observations and verdict. Unlinked accruals, dangling references and duplicate keys gate; orphan coding and missing source digests are advisory. The scope is the structure of declared linkage, never amount agreement. The spec's worked example is carried as the oracle-backed golden fixture (execution_hash 46b2cee4111553128514447ded7e205fb45bbdedccd75579f04c7ebc360d63d1).

Response

Successful tool execution result

linked_accrualsstring[] required

Accrual keys whose every declared reference resolves to a declared coding entry, in input order. An accrual that partly resolves is not here.

unlinked_accrualsstring[] required

Accrual keys declaring no reference at all, in input order. Gates the verdict.

orphan_codingstring[] required

Coding entry keys no accrual traces to. Advisory: recorded, never gating.

missing_source_refsstring[] required

Coding entry keys with no declared source_document_digest. Advisory: recorded, never gating.

duplicate_lineage_keysstring[] required

Keys declared more than once across the coding and accrual entries together, once per colliding key in first-repeat order. Gates the verdict.

overall'CLOSE_READY' | 'GAPS_FOUND' | 'INDETERMINATE' required

CLOSE_READY iff unlinked_accruals, dangling_trace_refs and duplicate_lineage_keys are all empty over a non-empty accrual set; INDETERMINATE on an empty or malformed register; GAPS_FOUND otherwise.

errorsstring[]

Present only on the indeterminate path, carrying the reason no linkage assertion was possible; non-empty exactly when the conditional compliance flag CLOSE_LINEAGE_INDETERMINATE is present (flag-mirror doctrine).
