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).

sim/economy/sim.py: 1,000 operators choosing MINE, PROVE, HYBRID or OFF per card class with their own clients; sortition by weight with the 10-s window then open claiming, external jobs with the 90/10 split, backlog rule, difficulty clamps, GBM price. Scenarios a to f, 5 seeds: no backlog, no window miss, hash floor 0.74 of pre-event. Traffic sensitivity finds the shortage oscillation only above the proving fleet's capacity (100 to 300 shards per block); at 100 the sortition window (10 s to 20 s) is the lever that removes it. docs/analysis/economy-2026-10-04.md holds the model, assumptions, results, worst case and the proposal (window = p90 shard time plus a swap, 25 s at today's targets; B_p tied to the live fleet), not applied.
