Three reports a CPA expects that the engine could not produce: - general_ledger(start, end): the canonical general ledger, organized by account in code order. Each account has its beginning balance, every posting in the period (date, entry, description, debit, credit, running balance on the normal side) and its ending balance, which ties to the trial balance. Each posting names its split: the one account on the opposite side of its entry, or "-Split-" when that side has several, so a compound entry (one debit, several credits) reads correctly from every account it touches. The entry-ordered listing the exports called a "general ledger" is really the general journal. - trial_balance_as_of(as_of): a trial balance is always as of a date. - members_equity(start, end, members): the statement of changes in members' equity for a multi-member LLC taxed as a partnership. Each member's capital roll-forward: beginning (capital plus their share of undistributed earnings), contributions, allocated net income (loss), distributions, ending. Allocation is by ownership share to the cent, the last member absorbing rounding, so totals are exact and the ending total equals balance-sheet equity; any equity change the roll-forward can't explain shows as "other" instead of disappearing. Shares must be positive and sum to exactly 1; capital accounts must be distinct equity accounts (LedgerError::InvalidMembers). - CashFlowLine.account: the account a line is about, so renderers can name members instead of account codes. Tests (every expectation computed by hand): trial balance as of Jan 31; February general ledger with beginning balances, running balances, a card that nets to zero, an inactive account still listed, and every ending balance tied to the trial balance; a compound entry's splits from all three sides; a two-member partnership where 666.67 and 100.01 split unevenly (333.34/333.33, 50.01/50.00), with and without closing January, tying to the balance sheet each month; bad member configuration.

Parity catalog
Every semantic feature we intend to clone, with its status. Updated in the
same commit as the feature. The floor never decreases: the count of
done items is monotonic across commits.
Statuses: done = implemented + invariant-tested + golden-covered.
partial = implemented but missing tests or goldens. todo = not started.
No other statuses.
Floor: 10 done (2026-10-10; fixed-asset register added).

Workflow/UI parity (QuickBooks/Xero reference) gets its own catalog when the egui phase starts; semantics come first.
Capability parity (AI-first phase)
Semantic parity (above) is about correctness: the engine computes the
right numbers. Capability parity is about usefulness: can the new system
do everything the GSheet+GDrive system does today? Tracked separately in
docs/capability-parity.md, with its own cutover rule (parallel run +
Stephen's approval). The two catalogs converge: when both are green, the
sheet retires.
