Report docs/review/redteam-2026-10-04.md: finality attacks s1-s8 plus 34% withholding, 50/50 long partition, F23 and
F24 custom runs, ordering harness, execution suite and EVM smoke, proving hostile tests and a proof flood, difficulty v2
timestamp forging in the simulator. New fails: the fast-time harnesses corrupt the u64::MAX sentinels of the override
(F25), a block or transaction flood grows the node by hundreds of MB in a minute (M30), the coinbase does not fit the
204-byte limit on mainnet, testnet and simnet parameters (M31). F23 and F24 reproduced on this build; F21's bound
measured at one window of the side's own DAA. Scenario scripts under tools/finality-attacks/redteam/.

attacks.py scenario 2 under rule v2 and Kaspa's DAA: a pulse never earns more blocks per hash than steady mining
(weight per hash 0.26 and 0.98); the economy simulator at the devnet's 124 MH/s; finality_sim scenario A (the
window is full on day 35 to 41 from zero history). The first fast-time s5 attempt failed on an override field the
integration build does not know; the re-run on the finality-fixes build is queued.

Spec 06 rows O-3.1, O-3.14, O-5.9 and O-5.11 carry the sweep's evidence (fix row 124 done). M20: the devnet's pruning
point leaves genesis between DAA 108,000 and 151,200, about 14:00 UTC 5 October to 01:00 UTC 6 October, after which a
fresh node rejects the honest pruning proof under the stub. The ledger ends with the sweep's status-update section;
the review file carries draft counts and the three findings.

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).

docs/bench-log.md: the fake-worker measurements (slow start one trip and 2.0 s restart, fake-fast guard in under
0.1 s, exit 43 at 8.8 s, CPU re-check stop at 0.5 s, stall guard at 60.1 s with STATUS lines through the silence,
one prepare per epoch with refused retries held; app: zero-rate restart at 79.6 s and faulted at 75.4 s on the
repeat, no-status restart at 90.4 s, silent node restarted at 150.7 s and synced 7.2 s later; no double restart on
the miner's own worker restart). Two defects the harness found are named with their fork commits.
docs/fud-ledger.md and the round-4 review table: M26, M27, X21 Fixed with the commits.
engine.rs: the miner's restart note no longer hides the fault reason on the card.
tools/reliability: the harness matches the miner's stderr lines where they are printed there.

Seven reviewers (Kaspa core, RandomX author, Ethereum client, GPU farm,
chip designer, exchange listing, regulator's analyst), three attacks each
against docs/spec, the execution design, the fork code and tonight's devnet.
0 fatal, 18 serious, 8 minor. New ledger entries M14 to M21, F14 to F18,
P11 to P15, E9 to E11, C13, L7, L8, G9, G10, X12; one cross-reference on P8.
