Max-testing pass, step 8. The final mutation run left 112 survivors (89% caught). Three agents triaged them by file, by the playbook's table: spec the boundary then test it, a law rather than one more pinned value, assert the real value, never weaken a test. Every expected value is hand-computed. - reports.rs (35): 28 killed, chiefly cash flow (inclusive start date, each line's sign and label, a loss on disposal moving to investing, financing designation), general ledger and members' equity date boundaries, and the balanced() checks (a real report nudged by a cent must stop balancing). 7 equivalent: four >/>= after an early return on zero; two in dead code (removed in this commit); one sign of a zero cleaned on output. - ledger.rs, kernel.rs, journal.rs, money.rs (52, plus one new): 49 killed, including every replay_* mutant at the core level (ids, accumulation, status, vendor tags, out-of-order refusal), FX rates, 0%/100% deductible boundaries, a dividend sweep with no income, the legacy member rounding at close, a bill paid on its own date, a liability-account reconciliation, mixed-currency entries (via serde), ISO 4217 minor units, Display/Debug. 3 equivalent: zero refused before a </<= check; a period whose end is in a closed period refused earlier; columns(0). - schedules, tax, analysis, payouts, assets, form1099 (25): 23 killed (schedule length 1-600, recurring end on its start, frequency parsing and stepping, cost of goods in tax net, a zero payout, disposal on the purchase date, quarter starts, labels); 2 equivalent (zero adds zero; days_held is provably >= 1). Two small production cleanups the triage surfaced: kernel::columns(0) returned a negative-zero credit that would print "-0" (regression a_zero_movement_has_no_negative_zero_column, shown to fail before); and cash_flow computed a book value it never used. Spec lines added where a boundary wasn't specified (cash flow's inclusive start and line signs, members' equity start date, payout with no deposit, disposal on the purchase date, bill paid on its own date). `just mutants` now runs core and store tests (the store's replay tests), not the whole workspace, which rebuilt the viewer for every mutant.
