Much of each schedule restates recurring charges both entities could have anticipated, yet the few mismatches that will obstruct consolidation remain embedded in the full exchange. Simple transaction matching occurs only after both sides have booked and does not make silence interpretable, reconstruct expected context, or detect when counterparties are using incompatible assumptions.","actors":["Legal-entity controllers","Intercompany accountants","Accounts-payable and accounts-receivable teams","Group consolidation accountants","Corporate controllership","Tax and transfer-pricing reviewers","Financial-systems administrators","Internal and external auditors with access to retained source records"],"observable_state":"For each authorized entity pair and close window, both sides expose the same versioned baseline of expected recurring intercompany flows, their independently recorded actual postings, signed residuals by agreement, currency, amount, classification, counterparty, and cutoff date, model uncertainty, source completeness, acknowledgements, reconstruction status, and any switch to full-schedule exchange.","consequence":"Intercompany mismatches can remain unresolved until consolidation because teams spend coordination time exchanging and comparing predictable schedule content. If expected content were suppressed without synchronized baselines and independent checks, a shared error, omitted posting, or stale agreement could instead appear as bilateral agreement.","affected_objective":"Surface and resolve consolidation-relevant intercompany mismatches earlier while preserving entity-level booking authority, complete accounting records, tax context, and independently auditable bilateral states.","intervention":"Establish an optional residual exchange protocol for a bounded set of recurring bilateral intercompany flows. Before the close window, the two entity controllers approve a shared, versioned baseline predicting each side's reciprocal booking from active agreements, recurring schedules, currency conventions, expected settlement timing, and chart-of-accounts mappings. Each entity still records its own actual entries in its ledger. A comparator calculates the difference between actual and predicted reciprocal states and exchanges signed residual packets rather than repeatedly exchanging the complete expected schedule. Each packet carries the baseline checksum, source status, uncertainty, and reconstruction context. The receiving entity combines the shared baseline with the residual to reconstruct the sender's declared state and compares it with its own posting. Consequence-weighted gates prioritize mismatches likely to affect elimination, cutoff, currency translation, tax treatment, or legal-entity reporting. Complete schedules remain retained and accessible; random bilateral periods and risk-stratified flows travel through an independent full-state audit path. Missing heartbeats, incompatible versions, new agreements, disputes, stale mappings, sustained residual structure, or excessive reconstruction error suspend residual exchange and require complete bilateral schedules. Accepted residuals may inform a separately approved future baseline but may not automatically post, net, eliminate, or settle transactions.","structural_mapping":[{"archetype_element":"Prediction target definition","domain_realization":"Predict the reciprocal accounting state expected from specified recurring intercompany agreements for one entity pair, period, currency convention, transaction class, and posting horizon."},{"archetype_element":"Generative model state","domain_realization":"A jointly approved baseline represents recurring charges, agreement terms, allocation drivers, expected invoices, settlement timing, account mappings, and uncertainty without replacing either entity's ledger."},{"archetype_element":"Model scope and horizon","domain_realization":"Each baseline is authorized only for named entity pairs, agreements, transaction classes, currencies, and close periods; new or amended arrangements are outside scope until separately approved."},{"archetype_element":"Predictive feedforward model","domain_realization":"The shared baseline produces the expected debit, credit, currency, classification, and timing on both sides before actual close postings are compared."},{"archetype_element":"Expected and actual behavior","domain_realization":"The expected reciprocal state is frozen before observation; actual postings are extracted independently from each entity ledger with timestamps, transaction identifiers, source completeness, and approval provenance."},{"archetype_element":"Prediction comparator","domain_realization":"The comparator preserves signed differences in amount and currency while separately identifying missing reciprocal entries, classification asymmetry, cutoff differences, duplicate identities, mapping changes, and incompatible settlement status."},{"archetype_element":"Prediction-error signal","domain_realization":"The exchanged message is the unexplained bilateral remainder plus enough baseline identity and context for the counterparty to reconstruct the sender's declared state."},{"archetype_element":"Precision-weighting rule","domain_realization":"Residual priority incorporates source completeness, mapping confidence, elimination consequence, currency and tax sensitivity, age, agreement status, and whether one or both entities independently observed the discrepancy."},{"archetype_element":"Residual propagation channel","domain_realization":"Version-tagged residual packets are routed between named entity owners and then to consolidation only when unresolved, consequential, overdue, or outside bilateral authority."},{"archetype_element":"Confidence and uncertainty state","domain_realization":"Each expected flow, observation, and reconstructed state carries confidence reflecting agreement freshness, allocation-driver quality, ledger-feed completeness, and mapping certainty."},{"archetype_element":"Update rule","domain_realization":"After disposition, residuals are classified as posting error, timing difference, legitimate nonreciprocity, mapping defect, agreement change, or model miss.
