• artifact_makeBuild a canonical financial artifact

  Assemble a Canonical Financial Artifact (scope, assumptions, citations, kernel plan, proof, reproducibility, auditHash) — the structured proof bundle a financial answer should carry. Every field is required and auditHash is verified, not just format-checked: it must be a digest a kernel call (ledger_post / ledger_audit_hash / ledger_verify_determinism / trace_run) actually returned in this session, or one this tool can recompute from the serialized `ledger` you pass alongside it. A fabricated value — even a well-formed one — is rejected. Validates that the kernel plan references core primitive…

• cashflow_statementDirect-method cash flow statement

  Derive an exact direct-method cash flow statement from a serialized ledger: operating / investing / financing flows per currency, with opening and closing cash. Cash accounts are detected by convention (Asset codes starting CASH or names containing "cash") unless cashAccountCodes is supplied. Self-checks that opening + netChange === closing. Kernel verified.

• cite_lookupLook up accounting citations

  Retrieve matching IFRS/GAAP facts and citations from the kernel knowledge graph for a query (e.g. "revenue recognition", "lease", "cost basis"). Use to ground claims in canon rather than asserting from memory.

• closing_generate_entriesGenerate closing entries to Retained Earnings

  Given a (serialized) ledger snapshot and close date, returns balanced JournalEntry[] that close Income/Expense to RE using the kernel. All entries are pre-validated. Kernel verified.

• depreciation_build_scheduleBuild depreciation / amortization schedule

  Exact straight-line (allocate) or declining balance schedule. Input cost/salvage/life/method. Returns periods with exact Money amounts as strings. Kernel-allocate based.

• entry_validateValidate a journal entry

  Run the kernel invariant check on a proposed journal entry: balanced debits=credits per currency, >=2 lines, positive amounts, no sub-scale precision, valid ISO date, no silent currency mix. Returns { ok, violations[] }. Always validate before posting.

• fx_compute_translationFX translation + CTA

  Translate ledger balances at asOf using provided rates into reportingCurrency. Returns holdings, translated totals, and the exact CTA plug amount. Always kernel-verified for balance.

• ledger_audit_hashAudit hash

  Compute the tamper-evident SHA-256 audit-hash chain for a serialized ledger. Any change to any field or line ordering yields a different hash.

• ledger_balanceAccount balance

  Net balance for an account in a serialized ledger, per its normal balance side. Pass "currency" for multi-currency accounts (otherwise fails closed). Returns all currencies via balancesByCurrency too.

• ledger_postPost an entry to a ledger

  Validate and apply a journal entry to a (serialized) ledger, returning the new ledger JSON plus its audit hash. The kernel refuses unbalanced state: an invalid entry is NOT posted and its violations are returned instead. Omit "ledger" to start from empty.

• ledger_trial_balanceTrial balance

  Every account in a serialized ledger with its current net balance (one row per currency).

• ledger_verify_determinismVerify determinism

  Rebuild a serialized ledger twice and confirm the two runs are byte-for-byte identical via their audit hashes AND that the fundamental equation holds. Returns { ok, hash }.

• ledger_verify_equationVerify accounting equation

  Verify Assets + Expenses = Liabilities + Equity + Income (per currency) holds for a serialized ledger. Returns { balanced }.

• money_computeExact money arithmetic

  Perform EXACT decimal money arithmetic with the kernel (decimal.js, never floats). Use this for every monetary calculation instead of computing in your own tokens. Ops: add, sub (same currency), mul, div (money x scalar), allocate (split by ratios, remainder to last), convert (via FX rate), compare.

• periods_create_lockCreate a period lock (hard close)

  Create an immutable PeriodLock fact for use with guarded posting. effectiveDate <= lockDate will be rejected.
