Max-testing pass, steps 2-4. Spec-blind tests (rank 1-2): four agents, each given only the specs and the public interface (doc comments and signatures, every body removed, never src/ or the existing tests), wrote tests/spec_reports.rs (62), spec_ledger.rs (72), spec_arap.rs (42), spec_assets_payroll.rs (50): hand-computed examples per scenario and a proptest law per invariant (conservation, partition, invariance, scaling, reversal cancels, "a refusal leaves the books unchanged" over random invalid commands). They found: 1. A refused payroll run changed the books: an all-zero run passed validation, then failed at post after creating seven payroll accounts and using up an entry id. validate_payroll_lines now refuses a run with no gross pay. 2. A refused add_account used up an account id (empty code, duplicate, unknown parent). The id is now taken only when the account is added. 3. Stale prose: close_period_to and members_equity still described the old last-member rounding. 4. Open (left #[ignore]d pending Stephen): depreciation_schedule's doc says "through the month containing" the date; the code prorates that month by days. GnuCash oracle (rank 3, an oracle never the spec): `just oracle` builds GnuCash 5.10 in a container pinned by base digest and package versions (oracle/gnucash/) and runs tests/oracle_gnucash.rs: 200 seeded random books built through wanderbooks (entries, foreign lines, reversals, monthly closes), every account's balance at month ends and random dates and each month's P&L, compared exactly: 15,800 comparisons. First run: 4,724 differences, all from foreign lines; without them, zero. Adjudicated from principles (rules.md B-3): wanderbooks booked foreign * rate unrounded ($108.34567); a ledger in one money holds no fractions of its smallest unit, and its cash must match a bank. Stephen decided: book in the base currency's minor unit, half away from zero. add_line_fx now rounds; minor units per ISO 4217 list one (2026-09-17, SIX), generated into Currency::minor_units and recorded in docs/spec/sources/iso-4217.md. Replay now takes the journaled base amount (replay_add_line_fx), so lines booked before replay exactly as booked (contract: books_written_under_older_rules_still_open). Now: zero differences, foreign lines included. Tests: 449, from 223. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01GWVo7x3UHw5kwCUaWxiejX
