Compute per-product revenue, cost, and margin per metric tonne. Revenue/MT = sum over metals of (assay% x payable% x index price), marked to market against inventory. Returns one record per product with metal contributions and inventory valuation.

Margin-per-tonne sensitivity for one product under price shocks: an 'all metals' row plus one row per metal, showing margin/MT under each configured shock (default -25%/-10%/+10%/+25%).

Implied per-metal index prices at which a product's margin/MT hits zero (uniform cost/revenue multiple applied to current prices).

Evaluate all configured offtake/feedstock contract structures at spot. Supports grade_multiplier, discount_profit_share, collar, and assay_payables. Returns each contract's outputs and binding flags (collar floor/ceiling binding, profit-share triggered).

Flatten a Xero Reports/TrialBalance payload into netted section balances (debit positive for assets/expenses, credit positive for revenue/liabilities/equity). Returns a dict keyed by section, each mapping account name -> balance.

Compute financial metrics used by loan covenants from a trial balance: revenue, net_income, ebitda, cash, current_ratio, dscr, debt_to_net_worth, total_debt, equity.

Test computed metrics against covenant thresholds. Each result reports the metric value, operator, threshold, compliant flag, and percentage headroom to the threshold.

Generate a full markdown covenant compliance certificate for a period. End-to-end: computes metrics, evaluates covenants, and renders the signable lender certificate in one call.

Run all anomaly rules over a set of invoices (and optional line items): duplicate numbers, entry lag, overdue-unpaid, amount outliers, unit-rate changes, new charge types, unexplained credits, and inconsistent tax. Header-level rules always run; item-level rules run only when line items are supplied.

Normalize an invoice number for duplicate detection: strips punctuation, uppercases, and drops common prefixes so 'INV123', '#INV123', and 'NV123' collide to the same canonical form.

Classify vendor invoices into the AP exception taxonomy: duplicate invoice (reuses audit normalize/duplicate rules), missing/mismatched PO, missing receipt, wrong legal entity, tax review, and ownerless approval. Each exception includes confidence and a stable reason code. Invoices without match-context fields are only eligible for duplicate and inconsistent-tax reuse.

Inventory ERP extracts, flag stale inputs, report reconciliation coverage, and compute hours-to-close from freeze (or earliest extract) to sign-off or the supplied now. Does not mutate state. Pass precomputed exceptions or invoices to include STP / double-handling.

Run the six-gate five-day close reference: source freeze, subledger cutoffs, reconciliation queue, evidence bundle, exception SLA, and controller sign-off. Classifies AP exceptions when invoices are supplied, optionally flashes covenants, and returns operator metrics (straight-through rate, double-handling minutes, stale-input rate, hours-to-close).

Accept a UiPath payload and route it to the matching deterministic engine: invoice audit, covenant certificate, contract evaluation, AP exception classification, or five-day close.
