This is a constraint on *which model +service produces the ruling*, not on the key. + +The **signing addresses are KMS-derived** and bear no on-chain relationship to the vendor.

Genesis seeding is the constructor (OQ-5) + +There is **no post-deploy `seed()` function**. The registry is populated **once, non-timelocked, in +the BondEscalation constructor** (`src/BondEscalation.sol`, "OQ-5 genesis seeding"): + +```solidity +constructor( + IACTPKernel kernel_, IERC20 usdc_, ICompositeMediator compositeMediator_, + address admin_, + address[2] memory fixedEvaluators_, // <-- genesis fixed set + address[] memory rotatingPool_, // <-- genesis rotating set + address umaOOV3_ +) +``` + +**Why non-timelocked at genesis (OQ-5):** every *later* mutation is guarded by the 2-day +`EVALUATOR_UPDATE_DELAY` (INV-17). If genesis seeding went through the same timelock, the very first +dispute would be unservable for 2 days after deploy. The constructor therefore writes the live +registry directly — exactly once, at the moment the contract comes into existence, before any +external party can interact with it.

No + private keys in any file; the deploy script emits Safe calldata, the Safe operator signs. +- **⚠️ CURRENT-STATE CORRECTION (on-chain verified 2026-07-03).** The mainnet kernel this v2 + redeploy replaces is **`0x048c811352e8a3fECd5b0Ec4AA2c2b94083CC842`** (V3, deployBlock 46212266, + 2026-05-19), vault **`0x262D5912A9612F0c66dA5d13B4E678D50ebC44b5`**, registry + **`0x64Cb18bfb3CC1aCb1370a3B01613391D3561a009`**, archive **`0x6159A80Ce8362aBB2307FbaB4Ed4D3F4A4231Acc`** + — **NOT** the pre-V3 `0x132B…2d29`/`0x6aAF…Fb99` pair this runbook was originally drafted against + (those are superseded; still on-chain but off the active path). **All §3 "OLD kernel/vault" + references must be read against `0x048c81…`/`0x262D59…` for mainnet.** +- **Sharper v2 justification (empirical).** The live V3 kernel `0x048c81` *already* exposes + `approveMediator`/`approvedMediators`/`mediatorApprovedAt`/`MEDIATOR_APPROVAL_DELAY`/`disputeBondBps()=500`, + but its runtime bytecode **lacks the `resolveDisputeWhilePaused(bytes32,uint8,bytes)` selector** + (`0x65f44ba0`, absent) and the F-6 `recoveryGrace()`/`recoverStalledInProgress(bytes32)`. Since the + CompositeMediator resolves disputes via `kernel.resolveDisputeWhilePaused` (`CompositeMediator.sol` + L155/L179), that method has **no selector on the current kernel** → dispute resolution would revert. + This is the concrete, verifiable reason v2 is required — independent of (and stronger than) the + immutable-coupling argument in §1. + +--- + +## 1. Why redeploy, not upgrade (G3 evidence) + +The kernel has **no upgrade path** and three downstream contracts hardcode it as `immutable`. +A new kernel address therefore cannot be "pointed at" by the existing peripherals — they must +be redeployed against it. + +| Contract | Field binding the kernel | Mutable? | Consequence for v2 | +|----------|--------------------------|----------|--------------------| +| `ACTPKernel` | n/a (no proxy; `new ACTPKernel(...)`) | **immutable code** | New address. | +| `EscrowVault` | `address public immutable kernel` (L29) | **immutable** | **NEW vault mandatory.** | +| `AgentRegistry` | `address public immutable actpKernel` (L41) | **immutable** | **Fresh registry** if registry must track v2; old registry stays bound to old kernel. | +| `ArchiveTreasury` | `IACTPKernel public immutable kernel` (L85) | **immutable** | **Fresh archive** if fee-archiving must follow v2; old archive stays bound to old kernel. | +| `X402Relay` | *(none — no kernel/vault reference)* | n/a | **No contract re-point.** Allowlist + SDK config only. | + +The kernel→registry link is the *only* re-pointable edge: the kernel stores the registry in a +**mutable** slot updated through a 2-day timelock (`scheduleAgentRegistryUpdate` → +`executeAgentRegistryUpdate`). Everything else is one-directional immutable coupling, hence the +fresh-deploy requirement. This is the structural justification for G3 ("redeploy required"). + +### 1.1 The mandatory `approveEscrowVault` — grep-confirmed call sites + +A v2 vault is inert until the v2 kernel approves it. Three internal fund-movement paths gate on +`approvedEscrowVaults[vault]` and revert `"Vault not approved"` otherwise +(`src/ACTPKernel.sol`): + +- **L1049** `_payoutProviderAmount` — provider settlement payout. +- **L1145** `_refundRequester` — requester refund (cancellation / split resolution). +- **L1156** `_payoutMediator` — paid-mediator fee payout. + +Because dispute resolution (`DISPUTED → SETTLED/CANCELLED`) routes through these helpers, +**even an admin-driven INV-6 resolution reverts** if the new vault was never approved. The deploy +script wires this atomically on testnet (admin == deployer) and emits it as **Safe TX 1 +(MANDATORY)** on mainnet. + +### 1.2 §5.1 resolver-authorization — grep-confirmed at the two "Resolver only" sites + +The resolver set is `{admin} ∪ {approved mediators past their 2-day MEDIATOR_APPROVAL_DELAY}`, +computed by `_isApprovedResolver` (`src/ACTPKernel.sol` L755). Per G1 the **pauser is NOT a +resolver**. Both DISPUTED-exit authorization checks were confirmed by grep to call the same gate: + +- **L781** — `_enforceAuthorization`, `DISPUTED → {SETTLED, CANCELLED}` edge: + `require(_isApprovedResolver(msg.sender), "Resolver only");` +- **L990** — `_handleCancellation` cancellation/split path: + `require(_isApprovedResolver(triggeredBy), "Resolver only");` + +(A third, pause-exempt occurrence at **L279** in `resolveDisputeWhilePaused` applies the same +`_isApprovedResolver` gate.) **Migration impact:** `_isApprovedResolver` is `{admin} ∪ {mediators}` +with *no stored kernel/vault address* — it carries no stale reference, so the resolver authorization +needs **no code edit** for v2. What it *does* require operationally is that the v2 kernel re-runs +`approveMediator(CompositeMediator, true)` (the OLD kernel's mediator approval does NOT carry over), +which re-arms the 2-day mediator timelock on the new kernel. That step is owned by the dispute-system +deploy (`DeployDisputeSystem.s.sol` / P6-1), not this script, and is listed in the checklist below. + +--- + +## 2. Redeploy order (what `script/DeployKernelV2.s.sol` does) + +1. Deploy `ACTPKernel` v2 — 6-arg F-6 constructor + `ACTPKernel(admin, pauser, feeRecipient, agentRegistry=0, usdc, recoveryGrace)`. + `recoveryGrace` = **7 days (604800) mainnet**, **1 hour (3600) testnet** (`>= MIN_RECOVERY_GRACE`). +2.

Retention SLA — single provider, ≥35-day floor + +| Parameter | Value | Why | +|---|---|---| +| **Provider** | **Pinata** (single, named — G-IPFS) | One provider per disputes so there is a single system-of-record pin and a single watchdog target.

It applies identically to the canonical prompt pin (AGIRAILS-owned) and to any +evidence bundle AGIRAILS is on the hook for (escalator-owned by default; AGIRAILS only if it +*separately* and explicitly takes the durability decision — the `AGIRAILS_PINS_USER_BUNDLES` UX copy +does **not** put AGIRAILS on this SLA hook). + +--- + +## 2. The two artifacts + +### 2.1 Canonical evaluator prompt — AGIRAILS-owned, FIXED cost + +- **What:** the exact prompt bytes (`DISPUTE SYSTEM/evaluator-prompt/canonical-prompt.md`) the 3-LLM + ensemble runs against. Pinned to Pinata as a deterministic CIDv1; that CID is referenced on-chain. +- **On-chain reference + change control (§4.2):** the active prompt CID is governed by the **same + 2-day timelock** the evaluator registry uses (`EVALUATOR_UPDATE_DELAY = 2 days` in + `src/BondEscalation.sol`, mirroring `proposeFixedEvaluatorUpdate` / `executeFixedEvaluatorUpdate`). + A prompt change is **never** instant: admin **proposes** the new CID (starts the 2-day clock), + anyone can fetch + diff the proposed CID during the window, then it is **executed**. Each ruling + carries `reasoning.evaluatorPromptCID` so it is attributable to the exact prompt version it ran + under. Step-by-step: `ops/aip14b/pin-canonical-prompt.md`. +- **Who pays:** **AGIRAILS.** The prompt pin + re-pin watchdog + on-chain CID upkeep are a **standing + FIXED operational cost**, amortized into the quote's `infra_margin` (`fixed_floor` term, §7.5.2 / + §7.5.8) — **NOT a per-dispute line item.** At ~500 disputes/mo the attributable fixed amortization + is ≈ $0.11–0.19/dispute, recovered **statistically** via `infra_margin`, not exactly. + +### 2.2 Per-dispute evidence bundle — escalator-owned by default, VARIABLE only if flag on + +- **What:** the versioned canonical-JSON bundle (`EVIDENCE-BUNDLE-SCHEMA.md`, schemaVersion `1.0.0`) + carrying the spec, deliverable-or-hash, dispute timeline, and any Tier-0 AI reasoning.

To AGIRAILS this is **`IPFS_per_bundle = 0`**; the quote does NOT include it. +- See §4 for the `AGIRAILS_PINS_USER_BUNDLES` UX exception. + +--- + +## 3. Re-pin watchdog + alert (AGIRAILS-owned) + +A lightweight cron (the **re-pin watchdog**) continuously enforces the §1 SLA on the +AGIRAILS-owned pins: + +1. **Liveness probe** — for the active on-chain prompt CID (and any bundle AGIRAILS has separately + committed to durability for): fetch via the Pinata gateway **and** an independent public IPFS + gateway, and assert the fetched bytes hash to the referenced CID (content-address check, not an + index check). +2. **Retention probe** — assert the pin's remaining retention ≥ the 35-day floor; if a pin is within + the alert margin of expiry, **re-pin the identical bytes** (deterministic ⇒ same CIDv1, §3 of + PROMPT-GOVERNANCE) so the on-chain reference never dangles. +3. **On-chain consistency probe** — assert the bytes pinned at the active CID still + deterministically re-pin to the **exact CID referenced on-chain**; a mismatch means a silent + prompt swap was attempted and MUST page (it would also have failed the on-chain timelock, so a + mismatch is a hard alarm). +4. **Alert** — any probe failure (unretrievable, sub-floor retention, CID mismatch) raises an alert + to the dispute-ops owner. Monitoring wiring is in `ops/aip14b/monitoring-alerts.md` (P5-4); + this SLA defines *what* the watchdog asserts, that runbook defines *where the alert lands*. + +The watchdog is part of the FIXED `infra_margin` cost (§2.1), not a per-dispute charge. + +--- + +## 4. The `AGIRAILS_PINS_USER_BUNDLES` flag — the §7.5.8 half-split gap + +**Default: `false`.** This is the one place where the fixed/variable classification can flip, so it is +specified exactly. + +- **`AGIRAILS_PINS_USER_BUNDLES = false` (DEFAULT, recommended):** escalator self-pins (§2.2), + `IPFS_per_bundle = 0`, nothing enters the quote, nothing is reported per-dispute.

The moment this is on, four things become + mandatory and turn on **automatically** so the cost stays recovered + reported: + 1. **It is a VARIABLE per-dispute cost** — bundle pinning stops being fixed and MUST enter the + unit-economics quote as the **`IPFS_per_bundle`** line + (`= min(storage_marginal + bandwidth_marginal, $0.01)`). + 2. **Hard cap `$0.01/dispute`** on `IPFS_per_bundle`, regardless of measured marginal bytes. + 3. **Size discipline** — with AGIRAILS paying, the escalator's incentive to keep the bundle small + is gone, so the **hard 100 000-token cap** (already enforced by `BundleTooLargeError` via + tiktoken `cl100k_base`, OQ-9) **plus** a per-dispute **stored-bytes cap** are enforced before + the pin. + 4. **Monthly envelope line** — the UX-pin total (`≤ $0.01 × monthly dispute volume`) is reported + in the §7.5.4 monthly bounded-subsidy envelope so the picture stays complete. +- **Durability-of-record is unchanged.** Even with the flag ON, AGIRAILS's pin is a **convenience + copy, NOT the durability-of-record.** The escalator is **still required to self-pin** for §8.6 / + UMA durability and the ≥35-day SLA. AGIRAILS is **not** on the ≥35-day hook for user bundles unless + it explicitly takes that as a *separately-priced* decision (distinct from this UX copy). + +> Leak L11 (R9): "AGIRAILS pinning user bundles for UX silently turns a fixed cost variable."

The canonical prompt has its own parallel mandate: `canonical-prompt.md` is the single + source, pinned deterministically (PROMPT-GOVERNANCE §3) so identical bytes ⇒ identical CIDv1. + +--- + +## 6.

No stuck funds (App-B item 1). +- **(b) Late callback** → `assertionResolvedCallback` early-returns with `UMACallbackIgnored` when + `d.resolved` is already true (INV-19). Idempotent. +- **(c) Re-entrant callback** → `nonReentrant` (§2 above). +- **(d) Unknown assertion** → both callbacks `require(disputes[disputeId].disputedAt != 0)`. +- **(e) Kernel admin-moved (MAJOR-2)** → the callback re-reads kernel state; if it is no longer + DISPUTED, it syncs locally and **returns without calling the mediator**, avoiding an illegal + transition that would otherwise revert UMA's whole `settleAssertion` and strand the UMA bond. +- **Forced-50/50 degradation warning (R17)** — the (a) path penalizes the rightful Tier-1 winner by + splitting rather than awarding. Mitigation is operational: an SDK helper + OPS runbook tell the + winner to call `settleAssertion` themselves (collecting the bounty), which is the incentive that + fixes settlement apathy. This is an economic, not a safety, concern. + +**Gas of the callback (R13, App-B item 2).** UMA forwards a *bounded* amount of gas to the callback. +The early-return (already-resolved) path is cheap.

The decision, function by function + +### 2.1 ALLOW — `openDispute` (caps + allowlist only, NO receipt yet) + +- **Why sponsor:** `openDispute` is the on-ramp. It moves **no funds** (it only snapshots escrow + + records `disputedAt`); the entry bond was already taken by the kernel on `DELIVERED → DISPUTED`. A + requester who has already been wronged should not also have to hold gas to *open* the dispute. +- **Why no receipt:** there is nothing to have paid for yet — this is the first step. It is gated by + the per-sender + per-day caps + the global circuit breaker (§3) only. +- **Abuse bound:** opening a dispute requires the txn to already be in kernel `DISPUTED` + (`require(txn.state == DISPUTED)`), which itself required posting the kernel entry bond. So + `openDispute` cannot be spammed for free — the costly step (the entry bond) is upstream in the + kernel, paid by the disputer, not sponsored. + +### 2.2 ALLOW — `submitAIRuling` (ONLY after a verified + consumed receipt) + +- **Why sponsor:** submitting a signed AI ruling is the "good citizen" path that resolves disputes + cheaply (Tier 0). We want it to be frictionless for keepers/agents. +- **Why receipt-gated:** the ruling bundle is produced by the **paid** x402 dispute-evaluator + (`x402-endpoint-deploy.md`, §4.3). Sponsorship is conditioned on presenting the **x402 settlement + receipt** for that evaluation (the `X-PAYMENT-RESPONSE` / facilitator receipt), **verified** (its + signature/settlement checked) and **consumed** (single-use; the receipt nonce is burned in the + paymaster policy store so it cannot sponsor two submissions). This ties our gas to a *real, paid* + ruling and blocks free spam of `submitAIRuling` with junk bundles. +- **Defense-in-depth:** even without the gate, a junk ruling reverts on-chain at + `_verifyEvaluatorSignatures` (`"Insufficient valid signatures"`), and reverted txs are only sponsored + inside the small carve-out (§3). The receipt gate makes even *valid-but-spammed* submissions + un-sponsorable without a paid evaluation behind them. + +### 2.3 ALLOW — keeper-recovery group (ONLY after a verified + consumed receipt) + +Sponsored functions in this group: **`settleUMAAssertion`**, **`retryMediatorResolution`**, +**`forceResolveStale`**, **`syncExternalResolution`**. + +- **Why sponsor:** these are the **permissionless liveness backstops** (INV-9). We want a keeper bot + (and any honest party) to be able to drive a stuck dispute to resolution without holding gas — this + is what keeps the "walk-away" guarantee real and what closes R17 (`settle-keeper-decision.md`). +- **Why receipt-gated:** to stop an attacker from burning our gas calling these in a loop, sponsorship + requires a **verified + consumed receipt** proving there is real work to do — e.g. for + `settleUMAAssertion`, a receipt/attestation that a UMA assertion exists and its liveness has expired + (the keeper bot's settle job emits/holds this); for `retryMediatorResolution`, evidence the dispute + is `mediatorRetryPending`. The receipt is single-use (consumed) so a function can't be re-sponsored + in a tight loop on the same dispute. `settleUMAAssertion` sponsorship is what makes the F-6 + settle-bounty bot self-funding (`settle-keeper-decision.md` §4.1) without a treasury subsidy. +- **No double-spend of gas:** because the receipt is consumed, the keeper is sponsored **once** per + legitimate recovery action; subsequent no-op retries (`d.resolved` already latched) are not + sponsorable. + +### 2.4 DENY — `proposeDirectly`, `challenge`, `escalateToUMA`, `finalize`, `claimEscalationRefund` + +Never sponsored. The caller pays their own gas. Rationale per function: + +| Function | Why DENY | +|----------|----------| +| `proposeDirectly` | Posts a Tier-1 bond on the caller's behalf — a participant staking their own money should pay their own gas; sponsoring lets an attacker open-and-stake the bond game on our gas. | +| `challenge` | Posts a **doubling** bond; the liveness-ping-pong griefing surface (Threat Model §5) becomes *gas-subsidized* if sponsored. The challenger has economic skin in the game and can afford gas. | +| `escalateToUMA` | Posts the **$500 UMA bond**; sponsoring the gas around a $500 voluntary escalation is pointless and invites griefers to spam escalation attempts on our gas. | +| `finalize` | Already self-incentivized by the on-chain **finalization bounty** (`max(pool*10%, $0.10)`, §7.9) — the keeper is *paid* to finalize, so it needs no gas subsidy.

Defeats single-key spam: a griefer would need to spin up many funded senders, each still bounded, and each `openDispute` still requires an upstream kernel entry bond. | +| **Reverted-tx carve-out** | sponsor reverts up to **~15%** of sponsored ops | Honest ops sometimes revert on races (e.g. `settleUMAAssertion` losing to a concurrent settler → `"Already resolved"`; `finalize`'s sync-only branch). A small reverted-tx budget keeps those from bricking honest keepers, but is capped so an attacker cannot grind free reverts.

On the + no-winner **SPLIT** leg the pool is left intact for proportional `claimEscalationRefund` — deducting + a bounty there would make Σ(shares) < accumulatedBonds and strand the bounty-sized remainder + (the split divisor `originalPool` is the FULL pool). This asymmetry is deliberate and matches + `finalize()`. +- **Safe degradation if not routed through the helper:** a *bare* `OOV3.settleAssertion(assertionId)` + (not via `settleUMAAssertion`) leaves `pendingSettler == 0` → **no bounty is paid** and the **full** + Tier-1 pool goes to the winner.
