Status lines updated from the bench-log, sim/results_v2.md, sim/difficulty/attacks and sim/economy where the
evidence existed and the ledger still said Open (M15, M17, M19, M24 fixed and live; F1, F7, F19, E12, E15 answered
with evidence; M26, M27, X21 fix built on miner-reliability; the rest annotated with what the experiment needs).
New: sim/economy/security_budget.py (E15 fee grid, price paths, hashrate response), fud-fixes section 2.5 (rows
117 to 126), docs/review/ledger-sweep-2026-10-05.md (the running table).
