Close Posting Lineage

Does every accrual you are about to close trace back to a coding entry you declared? You supply the two lists (each entry as a lineage key, a GL account, an amount, optionally a source document digest, and for accruals a traces_to list of coding keys); the node returns the accruals that resolve, the accruals with no reference at all, every reference naming a key nothing declares, the coding entries nothing traces to, the coding entries with no source digest, repeated lineage keys, and an overall CLOSE_READY, GAPS_FOUND or INDETERMINATE determination. Four stages in one deterministic pass: intake with fail-closed shape validation, key uniqueness, per accrual linkage classification, coding side observations and the verdict. It pairs with the interest accrual recompute (art-661) and the GL tieout recompute (art-665), which verify the numbers this node's declared entries are about.

Scope & reliance

The scope is the structure of declared linkage, so an accrual of 1200 tracing to a coding entry of 300 reads as linked here: amount agreement, document contents behind a digest, and posting are all outside what this node does. Unlinked accruals, dangling references and repeated lineage keys gate the verdict, while a coding entry nothing traces to and a coding entry lacking a source digest are recorded as observations only; an empty or malformed register returns INDETERMINATE. All inputs are caller declared and synthetic, and the thresholds are internal design rather than any accounting standard's rule. This node ships compute_proof_ready deferred; see the proof-status note below the results.

Lineage Verdict

Proof status

This node ships compute_proof_ready: deferred. No formal correctness proof has been produced for this kernel; the result above is a deterministic recompute, verified by a property-test floor and pinned to the build spec's worked example, not a proven one.

Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this exact tool, with this sample, and verify the artifact.

Run the AINumbers MCP tool `verify_close_posting_lineage`. Task: Month-end close lineage verdict over declared entries: which accruals resolve to a declared GL coding entry, which references dangle, which coding entries nothing traces to, which lack a source digest, repeated lineage keys, overall CLOSE_READY, GAPS_FOUND or INDETERMINATE, per CLOSE-COMMAND-CENTER-BUILD-SPEC-2026-09-23.md
Call it with arguments: {"policy_parameters":{"as_of":"2026-09-30","coding_entries":[{"key":"COD-1","gl_account":"6100-office","amount":1200,"source_document_digest":"doc-digest-1"}],"accrual_entries":[{"key":"ACC-1","gl_account":"2100-accrued-expense","amount":1200,"traces_to":["COD-1"]},{"key":"ACC-2","gl_account":"2200-accrued-interest","amount":300,"traces_to":[]}]}}
Verify before trusting: call `verify_execution_hash` on mcp.ainumbers.co (https://mcp.ainumbers.co/mcp) with the parameter `claimed_hash` set to the returned `execution_hash`, passing the full artifact the run returned (the object containing `policy_parameters` + `output_payload` + `execution_hash`; equivalently `policy_parameters` + `output_payload` with `claimed_hash`), not the bare hash string.
Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us.
