ARBITER: a full dress rehearsal with the gate. Four companies pay through it, a phone's passkey decides two payments, and it is attacked up to root on ARBITER's server Run 26 October 2026, 11:00 pm US Eastern (2026-10-27 03:00 UTC), code ecf52ec ================================================================================ WHAT THIS IS A dress rehearsal: all of ARBITER, run once end to end the way customers would use it, as on 13 October (2026-10-13-dress-rehearsal.txt). It runs on a disposable copy of production restored from that day's backup, never on production itself. Six made-up companies are set up through the product and send requests to the real AI models production uses (xAI's); the run's own reviewer accounts approve and reject what waits for review; then the run attacks the system and audits its own evidence. The executor, broker and database code are exactly those production runs. New since 13 October: four of the companies pay through THE GATE, a separate service on Cloudflare that holds the only credential that pays, and pays only when a passkey its owner granted approves the exact payment there (in production, a passkey on a person's own device; see /foundation/). This run used a test gate made for it, rehearsal-gate (gate id rehearsal-gate-1), which reports the same gate code as the production gate (version gate-4), with its own public log and its own Slack channel. A payment here is a payment instruction posted to that channel: no money moves. ARBITER's founder decided two of the payments with a passkey registered from a phone: approved one, rejected the other. RESULT: 115 checks passed, 0 failed. 30 steps are setup the product has no route for, most done as the database's owner or, at the gate, by the gate's owner, and marked so; 4 checks run only with the stand-in model and are skipped here. THE GATE, FROM ITS OWN LOG (this run's entries, #1466 to #2144; #1483 and #1484 are the gate expiring two requests earlier runs left) - 4 companies, 15 payment requests (and 10 more refused on arrival). 10 were paid: 9 approved by the run's software approver passkeys, 1 by the phone's passkey. 2 were rejected at the gate, one of them by the phone's passkey. 3 were left waiting, as the attacks needed: the request an outsider copied, whose payee the owner then unlisted; the payment root claimed in ARBITER's own records was paid; and root's own request for USD 49,999.99. After this run's tidying no passkey is granted that could approve them, and each expires unpaid. - The phone's passkey: request eb6e4e25, USD 12,000.00, approved (#2131) and paid, with the gate's signed receipt naming the passkey 81696d79d2f8d6a9 (#2132); request 3b5ce55b, USD 8,000.00, rejected with the same passkey (#2133). ARBITER recorded both outcomes with the gate's receipts (G4.2). - Root on ARBITER's server, holding the broker's own key for the gate, made 15 attempts (A5.3, from the attack's own record): 13 were refused outright, among them setup, an approval under the owner's passkey id, a real owner signature replayed, an approval made on ARBITER's own site, a payee of its own, an amount above every limit, another company, a rewritten request and a key of its own (registered, pending, then the request signed with it refused). The other 2 were accepted and went no further: a passkey of its own (anyone may register one; it stays pending until an owner activates it), and a USD 49,999.99 request signed with the broker's key, which the gate takes from that key's holder and which then waits for a granted passkey. It also forged a receipt in ARBITER's own records (A5.1): ARBITER showed that payment as executed while the gate still held it, unpaid, and the forged receipt does not verify with the gate's key (G7.2). Of the 15 attempts, 10 are in the gate's log: setup and a read are never logged, and its three unsigned attempts came after the outsider's flood had used up the hour's shared allowance for logging refusals. - An outsider (A1): an unsigned read of a request, a forged signature, a copied request and a copied approval were all refused; after 600 unsigned refused calls used up the hour's shared allowance for logging refusals, a refused request signed with ARBITER's key was still logged in that key's name. Another company (A2): a payee listed only for another company was refused, and one company's approver could not approve another's payment. The AI model, told in the request to pay an attacker's account (A3): the gate was asked for the account and amount that were submitted, not the model's answer. - The whole log, 2,144 entries, checks with the gate log checker (G7.1; the published copy, run on the saved log, prints the same), and replays step by step against the gate's TLA+ model (G7.3). EARLIER THE SAME EVENING (the same log holds it, entries #1 to #1465) - #1 to #777: the test gate started, the phone's passkey registered (#2), and check runs with the stand-in model. The first stopped at the start: the gate's setup code was not set yet. The next found a fault in the run's own tools (it kept a sign-in, so its "outsider" read as a signed-in approver of another company: the gate answered as for a stranger's guess, 404, where the check expected 401); fixed, the run after it passed. #777: the operator, with the test gate's owner key, revokes a key the first run had left pending. - #778 to #1465: a first attempt at this run, at 10 pm US Eastern: 110 passed, 5 failed, all five the run's own expectations, not ARBITER or the gate. The real model's answer to the USD 48,000 payment was flagged by a principle and held for a second review, which the run did not decide; and a permit for a test message, issued for 10 minutes, expired while the run waited for the phone. Both fixed (ecf52ec) before this run. In that attempt the phone's passkey approved both of its payments, though the plan was to reject one, and the gate paid both, exactly as signed: the checker lists them, #1441 and #1443. - Between the two, a run against a local copy of the gate (not in this log) checked the fixes. It also met the AI provider's rate limit (two real runs within half an hour) and a real answer blocked by a principle; neither was changed. WHAT IT DOES NOT SHOW - On this test gate, root on ARBITER's server could have made the gate pay. The gate's owner and every approver but the phone are SOFTWARE passkeys kept on that same server, and an approver granted for that company could have approved root's own USD 49,999.99 request. The attack never uses those keys: it shows what root can do WITHOUT them, which is its position against the production gate, whose owner is a passkey on the founder's phone. It shows nothing about root against a real owner's or approver's device. - Which device signed. The log shows that the phone's passkey signed; its signatures also mark it as a synced passkey (backed up by its passkey provider), so whoever controls that provider account is trusted too. That it was a phone, and the founder, rests on the founder's word. - Not money. The gate's payment is a message to a Slack channel; there is no payment rail yet. - The test gate is in the same Cloudflare account as the production gate. Cloudflare, and that account's login, are trusted, as for the production gate; that it runs the gate code /foundation/ names by its SHA-256 rests on its own word (version gate-4). - Made-up companies and a few dozen requests: not a customer's traffic, and not a load test. No customer uses ARBITER yet. ARBITER's own reviews are decided by the run's reviewer accounts, which a script drives. - Its log is public, so every request's terms are public on this gate (by choice; a customer's gate can keep its log closed). CHECK IT YOURSELF - The test gate: https://rehearsal-gate.jerrymcclintock1.workers.dev (/.well-known/arbiter-gate, and its log at /v1/log). The log will grow if the gate is used again; this run's tidying follows it at #2145 to #2155. - The copy of its log this run checked, entries #1 to #2144 (head 132dfe13a78f93d41a80aa334381ec184ed2d94e7352ad30db88e0b06fb707f5): https://consequenceaisystems.ai/runs/2026-10-27-rehearsal-gate-log.json SHA-256 34206e434cd77e399a8397e48046436ea062b1e6ad7122825044fd7028e70124 https://consequenceaisystems.ai/runs/2026-10-27-rehearsal-gate-about.json SHA-256 8dc817e674ed1c170d860aaf5e9f4190a95eb131f09628b885f687b9952f3ac4 - The checker, one file, unchanged since 16 October: https://consequenceaisystems.ai/runs/verify_gate_log.py SHA-256 5cf33bb32dbb8ca7eb7f3dde6b27c449093b5ad62ed098846d3da2d1a6e81f6d pip install cryptography python3 verify_gate_log.py --file 2026-10-27-rehearsal-gate-log.json \ --about 2026-10-27-rehearsal-gate-about.json It lists every payment the gate made and the passkey that approved it; its last two lines say everything holds and that every payment was approved, over its exact terms, by a passkey an owner granted. - The gate's TLA+ model, and the tools that replay a log against it (trace.sh, trace.py, TraceGate.tla, TraceGate.cfg), listed with their SHA-256 in https://consequenceaisystems.ai/foundation/model/e05ad81/SHA256SUMS and each at .../e05ad81/.
