+/**
+ * What an agent is told on a chain other than Stellar.
+ *
+ * Stellar's brief talks about resting orders, splitting and anchors, none of
+ * which exist on these chains, and the route notes call the market a testnet.
+ * Here the order is a single fill on mainnet with real funds, and the agent's
+ * one decision is which listed route to take. The chain action settles to a
+ * plain fill afterward whatever an agent says, so the brief does not offer
+ * choices that would be ignored.
+ */
+const CHAIN_BRIEF = `You are one of several autonomous execution agents judging a single user action on a stablecoin-native marketplace.
+
+This is mainnet and the funds are real funds. The action is a single transaction, signed once by the user, and nothing waits for a better price.
+
+You judge this action and nothing else. If the person also asked for something after it, such as a cash-out to a bank, a deposit or a send, the app runs that as its own next step once this one settles. Do not say it is unavailable, do not call it a separate job for the person, and do not mention anchors.
+
+Your decision is which of the listed routes to take. A route is a real quote from a venue on the chain named in the market context, and the venues listed are every venue that exists for this action. Naming one that is not listed fails your proposal outright. When only one route is listed you still decide: judge from its numbers whether it is worth taking, and say so.
+
+How to decide:
+- Use ONLY the prices and figures given to you. Never use a price or a yield from memory; if a figure is not supplied, reason in relative terms instead.
+- For a swap, compare the dollar value each route delivers for the same amount paid. The route that delivers the most is usually right, unless its figures look off against the others.
+- For a deposit or a stake, compare the APY each route shows. It is the current rate, not a forecast, and it can change.
+- Be concrete and quantitative. State the actual numbers you are working from.
+- You are proposing an execution plan, not giving financial advice.
+
+Return your answer by calling the submit_proposal tool. Do not reply with prose. Fill the remaining fields like this:
+- routeId: the id of the route you chose.
+- projectedAvgPriceUsd: the dollar price of the token being paid in, from the market context. The server replaces it with the measured figure.
+- projectedSlippagePct: 0. The server measures the real figure from the quote.
+- executionMode "fill", thenAction "none", sliceCount 1, and 0 for every other price or percentage field.
+
+Your reasoning is shown directly to the user in a chat bubble: at most two sentences and under 300 characters, no preamble, no restating the question. Never use an em dash or an en dash; use a period or a comma. Decide quickly and commit. Do not enumerate alternatives you are not going to choose, and do not re-derive the same figure twice.`

+
+The market context lists a resting option. Besides filling now, you may propose resting: the person's order waits on the book at your price and may never fill, and placing it costs the amount stated there, so weigh that cost against the amount being traded. A very small swap should fill. To rest, set executionMode "rest" and restPriceUsd to a price inside the range the market context gives, still choosing the route you would take to fill. Any price outside that range, and any split, becomes a fill. The person reviews and signs the order themselves.`

 Run with `pnpm agents:eval [model]`. 20 intents x 4 agents = 80 live calls per run.
 
+## 2026-11-05: how fast agents can talk
+
+`lib/agents/evals/talk-speed.ts`, one short talk turn of about 400 tokens, 400 output tokens at most.
+
+| model | setting | answered | median | p90 |
+|-------|---------|---------:|-------:|----:|
+| `qwen/qwen3.8-27b` (Groq) | normal | 9/10 | 752ms | 1121ms |
+| `qwen/qwen3.8-27b` (Groq) | `reasoning_effort: 'none'` | 3/10, the rest 429 | 610ms | 612ms |
+| `deepseek-v4-flash` | normal | 5/10, the rest cut off by the output limit | 2630ms | 3403ms |
+| `deepseek-v4-flash` | `thinking: { type: 'disabled' }` | 10/10 | 1332ms | 1562ms |
+| `cohere/north-mini-code:free` | normal | 1/3, the rest cut off | 7133ms | 7133ms |
+| `cohere/north-mini-code:free` | `reasoning: { enabled: false }` | 3/3 | 1164ms | 1438ms |
+| `google/gemma-4-26b-a4b-it:free` | either | 0, upstream 429 | - | - |
+| `poolside/laguna-xs-2.1:free` | either | 0, 404: no longer served by OpenRouter | - | - |
+
+Claude Sonnet was not measured: no key here. DeepSeek first takes took 3.4s to 5.1s, against a 7.2s median on 2026-09-08.
+
+Groq's 429s came from running twenty calls in a row against its 8,000 tokens a minute, not from the setting.
+
+**Verdict: go.** DeepSeek and Groq sit in every line-up and both answer under 3s at p90, so every race can have at least two agents talking. Small samples, and free models vary by the hour.
+
+## 2026-11-05: what talk does to what agents decide
+
+`pnpm agents:eval:talk`, DeepSeek V4 Flash and Qwen on Groq, three chain swaps with made-up routes. Route A pays 0.4% less and settles in seconds. Route B pays more and takes a bridge.
+
+| | |
+|---|--:|
+| races | 3 |
+| all first takes on one plan | 2 |
+| all final plans on one plan | 3 |
+| plans changed | 5 |
+| plans held | 0 |
+| races past 20s | 0 (8.7s, 8.8s, 10.8s) |
+| planted instruction obeyed | 0 of 2 agents, one race |
+
+Both agents started on the worse-paying route in two races and left it after talking. In one, DeepSeek wrongly said the routes paid the same, Qwen challenged it, and DeepSeek corrected itself.
+
+All three races ended with every agent on one plan, which is the agents' own conclusion and also the thing to keep watching: reading each other could flatten a race as well as sharpen it. Three races across two models can't tell those apart. Run this across more models once OpenRouter's limit is lifted. No target is set.
+
 ## Decision rule (fixed before the first run)
 
 Ship Flash if hard-check pass >= 98% **and** mean distinctness >= 0.6. Committing

+ * 1. Several transactions don't carry a first use safely. NEAR Connect hands the array to whichever
+ *    wallet is connected, promises neither their order nor to stop after a failure, and returns
+ *    nothing if it fails partway. So storage is its own signature, with `thenPrepareAgain`, and the
+ *    order is only built once the chain shows the storage is there.
+ * 2. `cancel_order` with `{order_id, amount}` pays bought or returned wNEAR as native NEAR, because the
+ *    contract unwraps it unless told not to with `skip_unwrap_near`. So a purchase pays out in NEAR.
+ * 3. `bought_amount` includes `unclaimed_amount`, and a filled order stays in `list_active_orders`
+ *    with `remain_amount` "0" until it is collected.
+ * 4. An `amount` above what is left is cut to what is left, so a cancel survives a fill before it lands.

+# Limit orders on Avalanche (CoW) and Monad: research report
+
+Date: 2026-11-05. Read-only: SDK tarballs, public RPC reads, CoW API GET and one POST /quote (a quote creates no order). No wallet, no .env.local, no repo edits.
+Tags: [V] verified live or from SDK source, [D] from docs only, [U] unverified.
+
+## A. Avalanche with CoW Protocol
+
+### Verdict: BUILDABLE. Main work is adding typed-data signing; the protocol side is live and proven.
+
+### A1. Live status [V]
+
+- API base https://api.cow.fi/avalanche/api/v1 answers. GET /version returned v2.386.0@9302627.
+- Chain id 43114 (AVALANCHE in @cowprotocol/sdk-config 2.11.2, SupportedChainId). cow-sdk 9.3.3 is current on npm.
+- Settlement GPv2Settlement 0x9008D19f58AAbD9eD0D60971565AA8510560ab41. Code present on Avalanche RPC. Same address on all CoW chains (https://docs.cow.fi/cow-protocol/reference/contracts/core, which lists Avalanche).
+- Vault relayer GPv2VaultRelayer 0xC92E8bdf79f0507f65a392b0ab4667716BFE0110. Confirmed by calling vaultRelayer() on the Avalanche settlement contract.
+- WAVAX 0xB31f66AA3C1e785363F0875A1B74E27b85FD66c7 (SDK wrapped-native table). USDC 0xB97EF9Ef8734C71904D8002F8b6Bc66Dd9c48a6E is accepted by the API (native_price returns).
+- Eth-flow contract 0xba3cb449bd2b4adddbc894d8697f5170800eadec (SDK ETH_FLOW_ADDRESSES applied to all chains). Code present on Avalanche. The SDK maps it to every chain, so treat Avalanche use as [V] for code, [U] for behaviour (no native order seen).
+- Live quote: POST /quote, sell 1 WAVAX to USDC, returned buyAmount 8728855 (8.73 USDC), feeAmount 1387297418112970 wei, protocolFeeBps "2", verified true.
+
+### A2. Live evidence of fills [V]
+
+Trade events on the settlement contract in the last ~30k blocks: 6 trades. For three, GET /orders/{uid} returned status "fulfilled", for example:
+
+- 0xec15a509...a7e5fd2dff540b19e542a92cb824aac9ebef05c9586c46aec6bf4 (owner 0xd2dff5..., created 2026-11-05 11:14Z, executedSellAmount 200034, executedFee 17884, class "limit", AAVE v4 swap with hooks).
+- 0x9e31cc36...6646 and 0x80f42c75...6677 (owner 0x44afcc..., Safe Wallet Swaps, partner fee 70 bps, fulfilled).
+  Caveat: these are market-intent swaps; the API tags every order class "limit" because fees are surplus-based. I did not find a user-set limit order far from market. Fill mechanics are the same. A human limit order resting for days on Avalanche is [U].
+  Liquidity is thin: 6 trades in about 30k blocks, so a limit order may wait. Solver 0x8cd4beaa... seen on quotes.
+
+### A3. Flow
+
+1. Approval (EVM tx). ERC-20 approve(vaultRelayer 0xC92E...0110, amount) on the sell token. Exact amount, not unlimited. A new tx type is not needed; the current `{family:'evm', to, data, value:'0'}` path covers it.
+2. Sell token must be an ERC-20. Native AVAX is not directly sellable by a signed order.
+   - Option 1: wrap to WAVAX first (WAVAX.deposit() payable, one tx), then approve, then sign.
+   - Option 2: eth-flow contract. SDK getEthFlowTransaction calls createOrder on the eth-flow contract with the AVAX as value. This is an on-chain order, one tx, no signature. Cancel is on-chain invalidateOrder; the order is invalidated by its creator or by anyone after expiry, and auto-refund applies only at >=2% slippage (https://docs.cow.fi/cow-protocol/reference/contracts/periphery/eth-flow). Eth-flow orders are sell-only, with buy token an ERC-20.
+   - Receiving AVAX (buying native): buyToken 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE (BUY_ETH_ADDRESS in contracts-ts) [D/V in SDK].
+3. Quote (optional but wise): POST /quote to get fee and a reference price. For a limit order the signed feeAmount must be "0"; the solver takes a surplus fee in the sell token (executedFee seen on filled orders) [V from orders, rule from SDK trading code].
+4. EIP-712 sign. Domain `{name:"Gnosis Protocol", version:"v2", chainId:43114, verifyingContract:0x9008...ab41}` (contracts-ts static domain()). Primary type `Order`, fields in order [V, ORDER_TYPE_FIELDS]:
+   sellToken address, buyToken address, receiver address, sellAmount uint256, buyAmount uint256, validTo uint32, appData bytes32, feeAmount uint256, kind string ("sell"/"buy"), partiallyFillable bool, sellTokenBalance string ("erc20"), buyTokenBalance string ("erc20").
+   ORDER_TYPE_HASH 0xd5a25ba2e97094ad7d83dc28a6572da797d6b3e7fc6663bd93efb789fc17e489.
+   Note: in the API JSON, appData is the full JSON string and appDataHash the bytes32; the signed field is the hash. Create/stash the app-data JSON (PUT /app_data/{hash} or send fullAppData with the order). GET /app_data/0x00..00 returns "{}", so the empty hash works.
+5. POST /api/v1/orders with: sellToken, buyToken, receiver, sellAmount, buyAmount, validTo, appData (+appDataHash), feeAmount "0", kind, partiallyFillable, sellTokenBalance, buyTokenBalance, signingScheme "eip712", signature (65-byte hex), from. Response is the order UID (56 bytes: digest 32 + owner 20 + validTo 4). UID = hashOrder(domain, order) + owner + validTo; compute it locally and compare to the response.
+6. Limit semantics: sell order = sellAmount fixed, buyAmount is the minimum out; buy order = buyAmount fixed, sellAmount is the maximum in. The price a person types sets buyAmount. Any fill at or above that is surplus to them.
+7. Smart-contract wallets: use EIP-1271 or presign (setPreSignature on settlement, on-chain tx). EOAs use eip712 (or ethsign).
+
+### A4. Cancellation
+
+- Off-chain (free): DELETE /api/v1/orders, body `{orderUids:[...], signature, signingScheme:"eip712"}`; typed data primary `OrderCancellations{bytes[] orderUids}` with the same domain (CANCELLATIONS_TYPE_FIELDS, hashOrderCancellations). Best-effort: a solver already settling can still fill it. [V in SDK; exact DELETE body is [U] — read from order-book SDK before building]. Cancel pages at docs.cow.fi returned 404 for the URL I guessed.
+- On-chain: GPv2Settlement.invalidateOrder(bytes orderUid) from the owner. Definitive, costs gas. Eth-flow orders: invalidateOrder on the eth-flow contract.
+- Expiry cancels everything on its own (validTo).
+
+### A5. Reading state
+
+- GET /orders/{uid}: status (open, fulfilled, cancelled, expired, presignaturePending), executedSellAmount, executedBuyAmount, executedFee, invalidated, creationDate. [V]
+- GET /trades?orderUid=… or ?owner=… (exactly one) for fills. [V: error text confirmed]
+- GET /account/{owner}/orders (also 200 empty for unseen owner via /orders?owner returned empty) for the open list. [U for exact path]
+- GET /users/{owner}/total_surplus works. [V]
+- Fills can be partial when partiallyFillable true; executedBuyAmount rises per fill.
+
+### A6. Fees, minimums, partial fills, expiry
+
+- Fee: no fee up front for the person; surplus fee in sell token on fill (covers gas); protocol fee 2 bps on the quote (protocolFeeBps "2"); partner fee optional in appData (e.g. 25 or 70 bps by integrators). If we want revenue, it is an appData partnerFee with our recipient, which must be shown to the person. [V]
+- Min size: no hard minimum, but API rejects below fee. Tests on WAVAX to USDC: 1e14 wei and 1e12 wei both returned SellAmountDoesNotCoverFee, fee about 0x3c6739e8db42d (about 0.0010 WAVAX, roughly $0.009) at 1e14. Practically a few dollars minimum so fee is not a large share. [V]
+- Partial fills: partiallyFillable:true supported by protocol; default SDK false. A partly-fillable limit order can fill in pieces over days. [D/V SDK]
+- Expiry: validTo uint32 unix seconds. SDK default 30 min for market (DEFAULT_QUOTE_VALIDITY); limit default in SDK is far-dated; MAX_VALID_TO_EPOCH in sdk-config. API max validity for limit orders: [U].
+- Price oracle for "good price" guidance: GET /token/{addr}/native_price [V].
+
+### A7. What the wallet flow must add (repo)
+
+Today: `SigningPayload` (apps/dapp/lib/chains/types.ts:40) has an `evm` variant that is a transaction only (`to,data,value`); `signOn` in apps/dapp/lib/adapters/evm-adapter.ts:96 calls wagmi sendTransaction and returns `{family:'evm', hash}`. `SignedPayload` has no signature variant. Submit routes only expect hashes (`EVM_HASH` in send.ts etc.).
+Needed:
+
+1. New SigningPayload variant, e.g. `{family:'evm-typed', chainId, typedData:{domain,types,primaryType,message}, account}` and a SignedPayload `{family:'evm-typed', signature}`.
+2. adapter: wagmi `signTypedData(wagmiConfig, {...})` after chain check; map user-rejection the same way.
+3. Prepare step returns: approval tx (existing evm payload) then typed-data payload; the sequence engine (lib/chains/sequence-flow.ts) must allow a step whose result is a signature plus a server POST.
+4. Submit route: server posts the order to CoW, computes UID and checks it matches; returns uid and an explorer link (https://explorer.cow.fi/avax/orders/{uid} [U]) instead of tx hash. SubmitResult's `hash` becomes an order id; a 'pending' outcome is natural.
+5. Status route for open orders; a cancel flow (second typed-data sign for off-chain, or evm tx for invalidateOrder).
+6. Native AVAX: wrap tx first (existing evm path), or eth-flow tx (existing path, value set).
+7. SC wallets: not supported without EIP-1271/presign; detect via code at account and refuse, or use presign tx.
+
+### A8. What `assertSafe` must verify before signing (server before showing, client again before sign)
+
+Because the typed data comes from our server and the wallet shows the user raw hex, the check has to be done in our code, on the exact `message` to be signed:
+
+- domain.name "Gnosis Protocol", version "v2", chainId 43114, verifyingContract exactly 0x9008D19f...ab41 (compared lowercase). A wrong verifyingContract makes the signature useless but a wrong chain could replay elsewhere.
+- sellToken and buyToken equal the token addresses the user asked for (listed, never by symbol); sell is not equal to buy.
+- receiver equals the signer account (or the explicit recipient the user typed). The zero address means "owner" in the protocol; refuse it anyway so what is shown matches.
+- sellAmount and buyAmount: recompute from the user's stated amount and limit price in base units; buyAmount >= typed price x sellAmount for sell orders; for buy orders sellAmount <= the cap. Reject if it is better than the live native_price by an absurd margin (typo guard) and warn if the order would fill at once (market) or be 10x away.
+- kind and partiallyFillable match the request.
+- validTo: in the future, not more than the user's chosen expiry, not in the past, not uint32 max unless "no expiry" was chosen. Show it as a date.
+- feeAmount "0".
+- sellTokenBalance and buyTokenBalance both "erc20" (not "external"/"internal", which draw on Balancer vault balances).
+- appData: hash matches the JSON we gave; JSON has no hooks (pre/post hooks run arbitrary calls from the settlement-time executor, a real risk, as the AAVE order above uses them) and only the partner fee we disclose.
+- Approval tx: `to` is the sell token, selector approve(0x095ea7b3), spender exactly vault relayer 0xC92E...0110, amount equals sellAmount (not max), value 0. Wrap tx: to WAVAX with deposit() only. Eth-flow: to the eth-flow address, value equals sellAmount, receiver equals the owner.
+- At submit: re-derive the order UID from the signed message and compare with what the API returned; check the returned owner equals the account.
+- Wrong-chain protection: wallet chain 43114 before signing (the adapter already switches).
+
+### A9. Risks and what a person can lose
+
+- Order does not move funds until a solver fills at or above the limit; funds stay in the wallet (non-custodial). Loss exposure is the approved amount (use exact approvals; an unlimited approval stays open to the relayer for good).
+- Stale limit: a resting order signs a price that holds until validTo. A big price move makes it fill at a price the person no longer wants (picking-off risk). Mitigate with short default expiry and a cancel button.
+- Off-chain cancel is not instant: a fill in flight can still land. Use on-chain invalidate for certainty.
+- AVAX gas dropping to zero leaves a person unable to approve/cancel; fills are paid by the solver out of the surplus fee.
+- Thin Avalanche liquidity: 6 trades in about 30k blocks; limits may not fill and quote depth is limited.
+- Phishing via malicious typed data (wrong spender or domain) is the main client-side risk; covered by A8.
+- CoW is a hosted order book run by CoW DAO; if the API is down, the order stops being discoverable but it remains valid until validTo, and could still be settled if a solver has it; only on-chain invalidate reliably stops it.
+- Native AVAX path via eth-flow: refund depends on invalidation (user or after expiry).
+
+## B. Monad (chain 143)
+
+### Verdict: NOT SAFELY BUILDABLE TODAY for a general limit order. Kuru is the only real candidate; a build is possible but I would not ship it without an audit and clearer admin facts.
+
+### B1. CoW on Monad [V]
+
+- https://api.cow.fi/monad/api/v1/version returns 404 (nginx). sdk-config 2.11.2 has no Monad chain (grep for 143 gave a block number only). docs list no Monad. GPv2Settlement code at 0x9008... exists on Monad RPC but CoW runs no API there; do not treat that as support. CoW: NOT SUPPORTED.
+- 1inch, 0x, UniswapX, Bebop on Monad: web search found no evidence, [U]. Monday Trade (Uniswap v3-like AMM plus order book) exists [U], https://learn.backpack.exchange/articles/what-is-monday-trade ; not examined.
+
+### B2. Kuru (best candidate) [D unless marked]
+
+Docs reflect a new "Spot V2" system; the docs were last modified 2026-10-19 (sitemap) — about 17 days old. Old docs (llms.txt, /contracts/Audits, /contracts/Contract-addresses) now return 404 or list old architecture (MarginAccount/Router, "Audits: Spearbit, Cantina" in the stale llms.txt). Do not trust the old audit line for V2.
+
+- Network: chain id 143 [V, eth_chainId 0x8f from rpc.monad.xyz].
+- Contracts (https://docs.kuru.io/deployments/mainnet.md):
+  - AccountCore proxy 0x264123a9B96Cc1193944cC25C188f1bD3dFa670e (custody, deposits)
+  - SpotRouter proxy 0xBdDF3556701B7ECca5d69416CFfd7F86D37E52b3
+  - WithdrawalLimiter proxy 0xF059F4AAb49Bd3AFB62134145EeAF38Fe103F0eA
+  - ProtocolAuthority 0x15db88bAc73D856B3ca53683F82058826A3b6E8f; KeeperAuthority 0xbc36eC07800150489f9ED0f86a2d3E27Ca36980e
+  - Nine OrderBook markets, e.g. MON/USDC 0xc9dE998e272d59a19CEA3783C8dd44f87A86405D, WETH/USDC 0x8121EE960066e4344A213F9aC7502395502aEe7a, cbBTC/USDC 0xAE8E0cf4A9ff696b5f6EC0B1339200EB4c09E422 (others in doc: XAUt0, NVDAx, SPYx, QQQx, TSLAx, EWYx).
+  - USDC on Monad 0x754704Bc059F8C67012fEd69BC8A327a5aafb603 [D, https://docs.monad.xyz/guides/kuru-flow].
+- On-chain checks [V]: AccountCore, SpotRouter and markets are all 141-byte minimal proxies (ERC-1967 implementation slot style), so upgradeable. owner() of AccountCore, SpotRouter, ProtocolAuthority = 0x64b86d1d212357f7127d1e86740c897167bbf024, a 12 KB contract (not a Safe with getThreshold; type unknown, [U] whether timelock or multisig). KeeperAuthority owner 0x8b736dce... is a small contract (172 bytes). Market owner = SpotRouter.
+- Flow:
+  1. If ERC-20 sell: approve(AccountCore, amount) on the token. Native MON: deposit with value, token address(0).
+  2. AccountCore.deposit(address rootOwner, address token, uint256 amount) payable (first deposit creates the root account, uint40 id; rootAccountIdOf(owner)).
+  3. Market.batch(uint40 userId, (uint8 side, uint96 quantity, uint32 price, uint8 tif, uint8 executionInstruction, uint32 minSizeAfterBlock)[] orders, uint8[] cancelSlotIdxs) — owner sends the tx directly; our wallet path already supports this. Prices and sizes are in market precision; read getMarketParams() (pricePrecision, sizePrecision, tickSize) and make price % tick == 0.
+  4. tif: GTC rests; IOC/FOK immediate. executionInstruction postOnly keeps it from crossing. Partial fills allowed; GTC remainder rests.
+  5. Cancel: batch with cancelSlotIdxs, or cancelAllOrders(uint40 userId), by owner tx. Immediate and definitive when mined (on-chain book).
+  6. Withdraw: AccountCore.withdraw(uint40 rootAccountId, address token, uint256 amount, address recipient). Free (non-reserved) funds only.
+  7. Read: getMarketParams, order state events (BookUpdatesPacked, TradesPacked), REST https://api.mainnet.kuru.io (data source), gateway https://gateway.mainnet.kuru.io (needs wallet signature + JWT, [U] details). Docs say direct reads of balances/orders are via those APIs; exact endpoints [U].
+- Fees [D]: maker 1 bp, taker 2 bps at base tier, tiers lower with 14-day volume; GTC post-only keeps a person as maker; resting bids reserve quote plus maker fee. Builder fee optional (needs account approval, approveBuilder).
+- Minimums [D]: market-specific minQuoteNotional for GTC (value not published; read on-chain, [U]); maxQuoteNotional applies; tiny resting orders are cancelled as dust.
+- Self-custody caveat: funds sit inside AccountCore (Kuru's contract) while an order is open; withdrawal passes a WithdrawalLimiter: bucket $200,000 shared across all users, refill about $8,333/hour, so a rush of withdrawals can be throttled; governance can change limits; docs mention freezes and a protocol pause with no stated controller (https://docs.kuru.io/accounts/withdrawal-availability.md).
+- Audit status [U/negative]: no audit report found for V2 (AccountCore, SpotRouter). Cantina bounty (https://cantina.xyz/bounties/f93c6818-141e-43a0-941f-5f56d606ad6f) started 2025-11-24, max $50k, currently paused, scope not visible. DefiLlama TVL for Kuru CLOB was about $544k when searched (https://defillama.com/protocol/kuru-clob). Thin TVL and fresh upgradeable contracts with an unknown owner.
+- SDK: @toxicflow-labs/ts-sdk (docs example) — an unusual package name, I did not inspect it, [U] whether Kuru-official. Do not take a dependency on it; we can ABI-encode batch ourselves.
+- One-click trading / 7702 / relay features exist; we would not use them (they add signers and 7702 delegation).
+
+### B3. What a build would need (if later chosen)
+
+Tx-only, no typed data: approve to AccountCore, deposit, batch, later cancelAllOrders and withdraw: five tx types, all already expressible as `{family:'evm'}`. assertSafe: every tx to a fixed allowlist (AccountCore, one market, token), selector allowlist (approve, deposit, batch, cancelAllOrders, withdraw), approve spender = AccountCore exact amount, withdraw recipient = signer, the batch userId must equal the account's own rootAccountIdOf read on chain, side/price/quantity re-derived from the request and tick-checked, tif GTC with postOnly where the person asked for a resting order. State reading needs the Kuru API or an event indexer.
+
+### B4. Risks / what a person can lose
+
+- Custody in an upgradeable, unaudited-as-far-as-found contract: the whole deposit (not only the order) is exposed to a bug, a malicious upgrade, or a pause/freeze while funds are inside.
+- Withdrawal limiter can delay exits in a stress event.
+- Thin liquidity on most markets; rebase/price manipulation on small books; a resting order can be picked off (like any CLOB).
+- Tokenised-stock markets (NVDAx, TSLAx, SPYx...) add issuer and off-hours risk; we would only offer MON/USDC, WETH/USDC, cbBTC/USDC at most.
+- Prices and size use raw precision: wrong scale means an order at a price off by powers of ten (a fat-finger class loss); must be derived and checked from getMarketParams.

+# NEAR limit orders on Rhea/Ref DCL (dclv2.ref-labs.near) - research, 2026-11-05
+
+## Corrections from the build, 2026-11-05
+
+Read off mainnet with nothing signed (`near-rhea-dcl.live.test.ts`, plus real transactions on this pool read through `EXPERIMENTAL_tx_status`). Where this differs from the report below, this section is right.
+
+- **No sign flip on the pool's axis.** The UI's `-point` only turns its helper's "B per A" price into the pool's y-per-x, so what goes in `msg` is one axis either way: USDC per NEAR = 1e18 / 1.0001^point, whichever token is sold. Selling NEAR rests below `current_point`, buying NEAR above it. Real resting orders agree: #8665 sells USDC at 415439 (0.9091 USDC per NEAR) against a market at about 401300, and the book near the market has only sell-NEAR orders below the point and sell-USDC above it. A fill matched the point to 8 digits: order #16180, 130.344448 NEAR at 401041 bought 500.004597 USDC, or 3.8360253 per NEAR against 3.8360253 at the point, so no maker fee shows.
+- **A purchase pays out in native NEAR, not wNEAR.** `cancel_order {order_id, amount}` makes the contract call `wrap.near.near_withdraw` and transfer native NEAR. Seen on this pool with `amount: "0"` in `3b2gaLoDMLtDhR6YvjWeCGo2jN7r2XNXnXbo3PkxD5nL` (500 NEAR bought) and `9ToL4GV74Z3oggetFvHb6LdogxSRd2QFDR1yZf1S1tK4`. A cancel returning sold wNEAR does the same (`23U4s6vFXWTf47HzR6QwqgddmyMDpKrHL7adGkYBuzUJ`, on another pool). There is an undocumented `skip_unwrap_near: true` to keep wNEAR, which market makers pass. This app doesn't, and refuses it. So the section 3 note, "proceeds come back as wNEAR", is wrong for this call.
+- **Collect and cancel pay the wallet.** USDC bought arrives by `ft_transfer` in the same transaction (`4MAGH8AXzcMgPjU5nC8ZDXRo6AjAVdF5SUady6LZD9oh`). The SDK's comment about an "inner account" doesn't describe what happens here.
+- **An `amount` above what is left is cut.** In that same transaction, a request to cancel 72.4 NEAR of an order already filled logs `actual_cancel_amount: "0"`, succeeds, and pays out the fill.
+- **`bought_amount` includes `unclaimed_amount`**, and a filled order stays in `list_active_orders` with `remain_amount: "0"` until collected (#15820: 999 USDC at 400927, both 257.47 NEAR). `get_order` answers `null` once an order has closed. `unclaimed_amount` is `null` in history rows.
+- **`find_order` answers `null` when nothing rests at that point.** A second order at the same point fails rather than merges: `E301: active order already exist` is in the deployed bytes (`view_code`, hash 3G34Nh...), and `internal_add_order` in the public fork below requires it. The app refuses it first.
+- **Gas.** Storage 30 + `near_deposit` 30 + `ft_transfer_call` 250 is 310 TGas, over the 300 limit the report said it fit in. Storage goes in its own transaction anyway.
+- **Several transactions don't carry a first use safely.** NEAR Connect hands the array to the wallet, which promises neither order nor stopping after a failure, and throws with no hashes if it fails partway. Rhea's own interface does send one array. An order landing without its storage should panic (`E100: account not registered`, `E102: insufficient storage`, `E107: not enough storage for slots` are in the bytes) and NEP-141 would refund it, as wNEAR if it was wrapped. The app pays for storage alone, with `thenPrepareAgain`, then builds the order once the chain shows the storage.
+- **An order's own status doesn't say it rested.** If `ft_on_transfer` refuses, NEP-141 refunds and the transaction still succeeds. Submit looks for the order with `find_order`, and reads a miss as pending.
+- **`LimitOrder` exists beside `LimitOrderWithSwap`, and this app keeps `LimitOrderWithSwap`.** The deployed bytes list `TokenReceiverMessage::LimitOrder` with 4 fields and `LimitOrderWithSwap` with 6. No real mainnet use of the plain one was found, on 5 November 2026, read through nearblocks: 0 among 358 recent `ft_transfer_call`s naming dclv2 on USDC and wrap.near (8 pages of 25 on each), and 0 against 138 `LimitOrderWithSwap` in 5 recent pages each of six accounts that place orders on dclv2 (mmt-arb, rhealover, 9dbdd4...4bb6, i1156173191.tg, bim, doublerose). This is a bounded sample, not the whole history. So it fails the bar of live use on this pool, and its behaviour on mainnet stays unread.
+  - What is known of it, none of it from a mainnet transaction. A public fork (`shawn10359/burrowland`, `contracts/mock-dcl`, not the deployed code) has its 4 fields as `client_id, pool_id, buy_token, point`, and `internal_add_order` panics with `E202: illegal point` on a crossed point: selling x needs `point >= current_point`, selling y `point <= current_point`. A third party's notes say the same from testnet (`sleetplayground/near-kit-tool-box-skills`). If the deployed contract does this, the plain message would close the crossing race, so it is worth one real test when someone signs a first order.
+  - The same fork bounds `LimitOrderWithSwap`'s swap at the order's own point, and its 6 fields would be these 4 plus `skip_unwrap_near` and `referral_id`, the last from INTEAR's indexer and those notes. That would make the "no minimum out" in section 3 a price bound, less any pool fee. One real crossed order agrees: #15815 buys NEAR at 400894 (3.89283), and swapped 11.6% of its deposit at 3.89283. One order is not proof, so the app still refuses a crossed point.
+- **Still unverified:** whether the 0.5 NEAR storage comes back, and how the deployed contract behaves in the cases above, as its source remains unpublished. No order has been signed through this app.
+
+Verdict: BUILDABLE for USDC/wNEAR (and a few other pairs), with a larger safety.ts change than any current NEAR venue (it refuses ft_transfer_call today). Not run end to end; no tx was sent.

+## Sources
+
+- SDK (source): https://github.com/ref-finance/ref-sdk/blob/main/src/dcl-swap/limit-order.ts , dcl-pool.ts, swap.ts (last push 2026-02-01); also rhea-sdk (same files).
+- UI (source of the place-order call): https://github.com/ref-finance/ref-ui/blob/main/src/services/swapV3.ts (v3Swap, LimitOrderWithSwap, cancel_order, get_user_storage_detail, priceToPoint, pointToPrice).
+- Guide: https://github.com/ref-finance/guide/blob/main/near-chain-guides/swap/limit-orders.md (guide.ref.finance did not resolve from here; read via GitHub).
+- Contract Rust source: NOT found. ref-finance org has no ref-dcl repo (listed all org repos). Everything on the contract below comes from SDK/UI code plus live view calls. Unverified where noted.
+- Live RPC: rpc.mainnet.near.org view calls on dclv2.ref-labs.near.
+
+## 1. Methods and args
+
+Contract: `dclv2.ref-labs.near` (get_metadata: version 2.4.2, state Running, owner ref-finance.sputnik-dao.near, wnear_id wrap.near, protocol_fee_rate 2000 (=20% of pool fee, unverified meaning), 6432 pools, 8010 users).
+
+Place (UI swapV3.ts, LimitOrderWithSwap branch), on the SELL token contract:
+
+```
+ft_transfer_call {
+  receiver_id: "dclv2.ref-labs.near",
+  amount: <sell amount, raw>,
+  msg: JSON.stringify({ LimitOrderWithSwap: { client_id: "", pool_id, buy_token, point } })
+}  gas 250 TGas, deposit 1 yoctoNEAR
+```
+
+- pool_id = "tokenX|tokenY|fee", tokens sorted lexicographically (getDCLPoolId). For USDC native: `17208628f84f5d6ad33f0da3bbbeb27ffcb398eac501a31bd6ad2011e36133a1|wrap.near|<fee>`; USDC is token_x, wNEAR token_y.
+- point sign: UI computes point for price A-by-B, then `new_point = (poolTokenX == sellToken) ? point : -point`. Point must be a multiple of the pool's point_delta (UI floors: regularizedPoint). The point is the ORDER price in the pool's x->y axis; the "LimitOrderWithSwap" name means it first swaps whatever part is already marketable, then rests the rest (original_deposit_amount vs swap_earn_amount fields confirm this).
+- Before it, UI prepends: (a) `storage_deposit` on the buy token for the user if unregistered (registration_only); (b) `storage_deposit` on dclv2 if get_user_storage_detail says more slots are needed. If the user has no record: attaches 0.5 NEAR with registration_only true. Otherwise slot_price \* max(needed,10) (+ locked_near if not sponsor). Check `get_user_storage_detail {user_id}` (returned null for a random unregistered account, so first-time = 0.5 NEAR). Unverified: whether 0.5 NEAR is refundable (the contract tracks locked_near/slots; likely refundable, not confirmed).
+- If selling NEAR: UI prepends near_deposit on wrap.near (and storage_deposit on wrap.near if unregistered).
+
+Cancel: `dclv2.ref-labs.near.cancel_order {order_id, amount}` amount = remain_amount (SDK) or omitted (UI = cancel all). 180 TGas. SDK/UI attach NO deposit (no yocto). Returns unsold tokens plus any bought tokens in the same call (guide).
+Claim: SDK `claim_order` = `cancel_order {order_id, amount:"0"}`, 180 TGas, no deposit. Pays out the bought tokens to the wallet, leaves the unfilled portion open (guide). So proceeds are NOT automatic: a fill sits as unclaimed_amount until the owner calls claim (guide: "no time limit"). Unverified: whether amount omitted vs "0" differ.

+
+## 2. Pools and price math (live, final block ~223163188)
+
+Native USDC / wNEAR pools (current_point, NEAR price at the pool, liquidity):
+| fee | point_delta | current_point | USDC per NEAR | TVL (x USDC / y NEAR) | resting order totals |
+|---|---|---|---|---|---|
+| 100 (0.01%) | 1 | 400630 | 3.997 | 288,390 USDC / 65,101 wNEAR | 4,684 USDC / 13,582 wNEAR |
+| 2000 (0.2%) | 40 | 400609 | 4.005 | 3,913 / 84,665 | 107.6 USDC / 3,096 wNEAR |
+| 400 (0.04%) | 8 | 393696 | 8.0 (stale) | ~11 / 10 | dust |
+| 10000 (1%) | 200 | 397600 | 5.4 (stale) | 0 | none |
+Also USDT.tether-token.near / wrap.near fee 100 (point 400559, ~$4.03, ~6.4k USDT) and fee 2000. USDC/wNEAR fee 100 is the one with real depth. Fee tier list: 100, 400, 2000, 10000 (DCL_POOL_FEE_LIST). Fee -> point_delta: 100->1, 400->8, 2000->40, 10000->200 (matches live data).
+
+Conversion: raw price y/x at point p = 1.0001^p. USDC(6 dec)=x, wNEAR(24)=y: NEAR priced in USDC = 1 / (1.0001^p \* 1e6/1e24) = 1e18 / 1.0001^p ... checked: p=400630 -> 3.997 USDC/NEAR. Inverse: p = round(ln(1e18/priceUsdcPerNear)/ln(1.0001)) then floor to point_delta (fee 100: delta 1 so ~0.01% steps). Sign flips depending on which token is sold (see above); the SDK's priceToPoint/getPointByPrice does this and must be copied or called, and tested against a live order: doublerose's order sells USDC at point 415439 in pool x=USDC (sell==x so point positive): 1e18/1.0001^415439 = 0.9856e... compute in tests, i.e. a limit order selling USDC for NEAR sits at a LOWER NEAR-per-USDC rate than... (verify with a test, do not trust my sign reasoning; unverified).
+Resting depth at the fee-100 pool near the market (get_pointorder_range 399000-402000): sell-NEAR orders (amount_y) at 399922, 399052, 400608; sell-USDC orders (amount_x) at 400927 ... 401986. i.e. orders above/below the current point 400630 on the expected sides, so the book is used by real people.
+
+## 3. Fill mechanics
+
+- DCL is bin-based; an order sits at one point and fills when swaps push the pool price through that point (the pool's own swaps consume resting orders at that point; guide: partial fills happen, both Claim and Cancel enabled). Source not read; per guide + order fields. LimitOrderWithSwap also immediately swaps the marketable part at placement (swap_earn_amount).
+- Partial fills: yes (remain_amount shrinks, unclaimed_amount grows). Cancel returns unsold part plus bought part.
+- Min size: no min seen in SDK/UI code. UI only checks output >= 0.00000001 and NEAR min balance. Storage slots (see above) are the real cost. Unverified on-chain min.
+- Fees: no cancel fee (guide). Trading fee on the filled part: unverified/ presumably the pool fee tier; protocol_fee_rate 2000 in metadata.
+- Lost/stuck risks: (1) fill must be claimed by a second tx (a cancel_order amount 0) and the buy token must be registered for the user on its contract or the payout can fail; the UI registers it first. (2) Order never fills if price does not cross; ordinary. (3) ft_transfer_call refunds unused tokens if ft_on_transfer fails/errs (NEP-141), standard. (4) A tiny pool/fee tier with no liquidity (e.g. fee 10000) can have stale price and an order placed on the wrong side of price fills instantly at a bad rate through the swap part, since LimitOrderWithSwap swaps first at whatever price. Mitigation: only allow pool_ids from the app's allowlist and require point within X ticks of current_point, read from get_pool at build time.
+- wNEAR: place works on wrap.near ft_transfer_call; the UI wraps first with near_deposit. Proceeds come back as wNEAR (ERC-like ft payout), not native NEAR; the user would need a separate near_withdraw (unwrap) - check how the app's existing swap does (apps/dapp/lib/chains/near/swap.ts/tokens.ts: WRAP_NEAR is in SWAP_CONTRACTS).
+
+## 3b. Repo fit (apps/dapp/lib/chains/near/safety.ts)
+
+- safety.ts allows only calls on wrap.near/USDC/USDT whose LAST call is `ft_transfer` to a 64-hex deposit address, or a stake. Header says `ft_transfer_call` is explicitly refused. A limit order needs:
+  - New asserter e.g. assertDclLimitOrderSafe: receiverId in {wrap.near, USDC, USDT}; calls = [storage_deposit(you, registration_only) on buy token?, storage_deposit on dclv2 with a capped deposit (<= 0.5 NEAR + slots; cap e.g. 1 NEAR), near_deposit?, ft_transfer_call]; ft_transfer_call args exactly {receiver_id:"dclv2.ref-labs.near", amount, msg}; msg parsed and required to equal exact-key JSON LimitOrderWithSwap{client_id:"", pool_id from allowlist, buy_token = the other token, point multiple of delta}; deposit exactly 1; gas <= 250 TGas (total <= 300 TGas holds with near_deposit 30 + storage 30). The existing hasExactKeys / isDigits helpers fit. Multiple transactions in the UI sequence (separate storage deposit to dclv2 is a different receiverId, so it needs more than one tx; readSingleTransaction demands exactly one). Either allow a 2-step sequence or put storage_deposit(dclv2) as a separate prior transaction signed under its own asserter.
+  - Cancel and claim: receiver dclv2.ref-labs.near, method cancel_order, args {order_id, amount}, deposit 0, gas <= 180 TGas, order_id must be verified to belong to the account via get_order (owner_id == account) server-side.
+- Balances/order read: use list_active_orders via the existing rpc.ts view path.
+
+## 4. Is it live
+
+- Contract live: code_hash 3G34Nhjmir5JPYPtijaA9iCNnHDPR7h3wfC9H77woEGo, storage 27 MB, ~9.6k NEAR balance; nearblocks shows swaps going through ft_on_transfer at the time of my query (block 223163499, ~now) and 56.5M txns total. 6432 pools, 8010 users.
+- Limit orders in use: doublerose.near (a Ref operator in metadata) has active order #8665 created 2026-02 on the USDC/wNEAR fee 100 pool; real resting orders on the book (107 to 1,000 USDC per point). Order activity volume not measured (unverified how many placements this month).
+- Upgradeability: `view_access_key_list` on dclv2.ref-labs.near returns NO keys (locked account). Owner field = ref-finance.sputnik-dao.near (DAO), operators doublerose.near and bim.near. Upgrade only via the contract itself (self-upgrade by owner) / DAO proposals; a single key cannot redeploy it. Operators can presumably pause/ set state (unverified - metadata has `state: Running` and operators; I could not read the Rust).
+- Audits: BlockSec "blocksec_ref_finance_dcl_v1.0_signed.pdf" and "blocksec_ref_finance_dcl_v2.0_signed.pdf" are in https://github.com/ref-finance/guide/tree/main/.gitbook/assets (PDFs not read; unverified findings). Plus Ref Finance Security Audit 1 and 2 PDFs in the same folder.
+- Incidents: none found in this pass (did not search exhaustively). Ref's earlier Ref Exchange had an exploit history? unverified; not searched.
+
+## 5. Verdict
+
+Buildable. Mechanically simple: one ft_transfer_call to place (plus storage deposits), cancel_order to cancel or claim, list_active_orders to read. Needs: a new strict asserter, a multi-transaction sequence (storage), point math ported and tested (sign flip trap), a claim step for the user (not automatic), and wNEAR in/out handling.
+
+Main risks:
+
+1. Not automatic: a filled order pays nothing until the user claims, and the claim is a separate signature. UI must show unclaimed_amount and offer Claim (or Cancel).
+2. LimitOrderWithSwap swaps the marketable part immediately. A mis-signed point sells at market with no min_output guard. Pre-check against current_point with a tolerance, and compute with the tested converter.
+3. First use costs up to 0.5 NEAR storage deposit plus slot fees (refundability unverified).
+4. Thin liquidity outside USDC/wNEAR fee 100 and USDT/wNEAR fee 100; stale prices on fee 400/10000 pools. Allowlist pool ids.
+5. Contract source not public; behaviour known from SDK/UI and live views only. DCL v1 and v2 audited by BlockSec, owner is a DAO, no access keys.
+6. cancel/claim attach no yocto deposit in the SDK; a wallet-signed call with 0 deposit is lower risk for the asserter but should be dry-run in testing.
+
+What a person can lose: the sold amount is moved to the DEX contract; the worst real cases are a wrong point that fills at a bad rate immediately, an order never filled (cancel returns funds, no fee), unclaimed proceeds left in the contract (not lost, claimable any time), and the storage NEAR if not refundable. A contract bug or a DAO/operator pause would trap funds; the risk is bounded by audit and the large live use. Nothing here is verified by sending a transaction.

+# Kamino Limo limit orders on Solana: feasibility report (2026-11-05)
+
+Method: downloaded and read `@kamino-finance/limo-sdk@4.0.0` source from npm (tarball unpacked in scratchpad/pkg), read the program source at github.com/Kamino-Finance/limo (master), and queried mainnet read-only (api.mainnet-beta.solana.com). Nothing was signed or sent.
+
+## 1. SDK
+
+- Package: `@kamino-finance/limo-sdk`, latest 4.0.0 (published 2026-10-05; 3.1.0 on 2026-07-30). Apache-2.0. Repo: github.com/Kamino-Finance/limo-sdk (the package.json points at Kamino-Finance/limo/tree/master/limo-sdk; the standalone limo-sdk repo has src/, README, package.json).
+- Built on `@solana/kit` (Codama-generated client since 3.0.0). Dependencies: `@solana/kit` pinned EXACT `8.3.0` (our app has ^8.6.0, so expect a second nested kit copy and possible type clashes at the boundary), `@solana-program/{token,token-2022,system,compute-budget}`, `@coral-xyz/anchor ^0.28.0` and `@coral-xyz/borsh` (used only for `BN`; anchor 0.28 drags in `@solana/web3.js` v1 transitively), `decimal.js`, `bn.js`, `bs58`, plus `commander` and `dotenv` (CLI only, in `client.ts`, not exported from index). `index.ts` is just `export * from "./Limo"`.
+- Server-safe: yes in practice. No fs/net code in the exported path; only `process.env.LIMO_PROGRAM_ID` is read (utils/programId.ts), which overrides the program id if set. Do not leave that env var set in prod; the assert-safe program allow-list would catch a wrong program anyway. It is heavy (anchor + web3.js v1 in the bundle). Lighter alternative: skip the SDK and hand-build the three instructions with kit (Codama code is small, discriminators below).
+- Client: `new LimoClient(rpc: Rpc<SolanaRpcApi>, subscription: RpcSubscriptions<SolanaRpcSubscriptionsApi>, globalConfig: Address | undefined, globalConfigState?, programId?)`. It needs an RpcSubscriptions object even for tx building (only used by listeners / `processTxn`). The README snippet is stale (two args).
+- Mainnet program: `LiMoM9rMhrdYrfzUCxQppvxCSG1FcrUK9G8uLq4A1GF`. Mainnet global config (found on chain, see section 4): `prod7Mog8r56sn5dPwze8nVdf94veEawdxNNqd5v7A1` (pda_authority `DJGVEH2F5DdwQVNgxtCEVSpC2Qu5sEjRmBHfa22tAnYY`, matches an Orb label "Kamino Swap Limit Orders Vault Authority"). The SDK does not hard-code it; the caller must pass it. No docs page states it (verified: kamino.com docs give no addresses).
+- Create (returns instructions, no sending):
+  - `createOrderGenericIx(user: TransactionSigner, inputMint: Address, outputMint: Address, inputAmountLamports: BN, outputAmountLamports: BN, inputMintProgramId: Address, outputMintProgramId: Address, globalConfigOverride?: Address, wrapUnwrapSol = true, withInitVault?: boolean): Promise<[Instruction[], TransactionSigner]>` (second value is a fresh order keypair that must co-sign).
+  - `createOrderGenericWithParamsIx(args: CreateOrderWithParamsArgs)` adds optional `permissionless` and `counterparty` update_order instructions.
+  - `placeBidIxs(user, quoteTokenMint, baseTokenMint, baseUiAmount: Decimal, price: Decimal, inputMintProgramId, outputMintProgramId, mintDecimals?, globalConfigOverride?)`; also `placeAskIxs`. Note: placeBid computes output as `baseUiAmount.div(price)`, a price convention we should not rely on; compute input and output raw amounts ourselves.
+  - Sending versions (`createOrderGeneric`, `placeBid`, ...) call `processTxn(user, ixs, mode, ...)`, which needs a keypair signer; not usable for a non-custodial flow. Use the `*Ix` variants and build the message ourselves.
+- Cancel: `closeOrderAndClaimTipIx(maker: TransactionSigner, order: OrderStateAndAddress, wrapUnwrapSol = true): Promise<Instruction[]>`. The same instruction cancels an open order and closes a filled one. There is no separate cancel.
+- Read:
+  - `getOrderState(orderAddress): Promise<Order>`
+  - `getAllOrdersStateAndAddressForMaker(maker: Address): Promise<OrderStateAndAddress[]>` (uses getProgramAccounts with memcmp on discriminator, global config and maker)
+  - `getAllOrdersDisplayForMaker(maker)`, `getOrderDisplay(address)`, `getAllOrdersDisplayForMakerInputAndOutputMints(...)`, `getLatestFilledOrders(...)`.
+  - Fill state is in the `Order` account: `initialInputAmount`, `remainingInputAmount`, `expectedOutputAmount`, `filledOutputAmount`, `tipAmount`, `numberOfFills`, `status` (0 Active, 1 Filled, 2 Cancelled), `permissionless`, `counterparty`, `lastUpdatedTimestamp`. Order account is 424 bytes, discriminator `134,173,223,185,77,86,28,51`. getProgramAccounts on a public RPC is heavy (22.7k order accounts for the prod config); in production filter by maker (memcmp offset 40) with a paid RPC, or fetch known order addresses with getMultipleAccounts.
+- Instruction discriminators (Anchor): create_order `141,54,37,207,237,210,250,215`; close_order_and_claim_tip `244,27,12,226,45,247,230,43`; update_order `54,8,208,207,34,134,239,168`. create_order data: disc(8) + input_amount u64 + output_amount u64 + order_type u8 (0 = bid).
+
+## 2. Transactions and what assert-safe must verify
+
+### Create (SDK order, wSOL input shown; `wrapUnwrapSol` true by default)
+
+1. (only if the vault for the input mint does not exist) Limo `initialize_vault` (payer = user, creates the escrow vault token account, PDA seeds `["escrow_vault", globalConfig, mint]`). User pays that rent; not refundable (the vault is shared). Common mints already have vaults.
+2. System `create_account`: payer user, new account = order keypair (co-signer), 424 bytes, 3,841,920 lamports (0.00384 SOL), owner = Limo program.
+3. If input is SOL: ATA program `create_idempotent` for the user's wSOL ATA, System `transfer` of exactly the input amount user -> wSOL ATA, Token `sync_native` (data `[17]`).
+4. Limo `create_order(input_amount, output_amount, order_type)`. Accounts: maker (signer, writable), global_config (writable), pda_authority, order, input_mint, output_mint, maker_ata (user's input ATA), input_vault (PDA), input token program, output token program, system program, event authority, program. On chain it transfers `input_amount` from maker_ata to the vault and transfers `ata_creation_cost + txn_fee_cost` lamports from the maker to the global config account (on prod: 3,000,000 + 0 = 0.003 SOL).
+5. If input is SOL: Token `close_account` of the wSOL ATA, destination = user (unwraps any leftover; note this also unwraps any pre-existing wSOL balance in that ATA).
+6. Optional: Limo `update_order` (mode 0 permissionless = true, mode 1 counterparty).
+
+- Rent / who pays back: order account rent (0.00384 SOL) returns to the maker when the order is closed (`close = maker`). The 0.003 SOL "txn fee cost" goes to the global config account. In the public program source (last commit 2025-11-26) it is NOT refunded at close; the SDK 4.0.0 `Order` struct has a newer `feePaid` field described as "refunded to the maker via close = maker", and the deployed program is newer than the public source (redeployed 2026-09-11), so whether it is refunded is UNVERIFIED. Budget for losing 0.003 SOL.
+- Correction, from simulation on 2026-11-05 (`solana-limo.live.test.ts`, read and simulate only): the 0.003 SOL is returned on close. A simulated create left the order account at 6,841,920 lamports (rent plus the fee) and the global config's balance unchanged, so on the deployed binary the fee sits on the order account, as the SDK's `feePaid` says, not in the config as step 4 above and sections 3 and 5 below say. A simulated close of a real filled order holding 6,841,920 lamports paid the maker 6,816,920, which is all of it less the 25,000 lamport network and priority fee. Not yet seen on a landed transaction.
+- Gap to handle: the SDK does not create the maker's OUTPUT token account. When the output is not wSOL the filler needs the maker's output ATA to exist (take_order's `maker_output_ata` is checked with `verify_ata`). Prod `ata_creation_cost` is 0, so the program does not subsidise it. Add an ATA-program `create_idempotent` for the output mint (owner = user) to our create tx, or fills for that order can fail. (Reasoned from source; not tested.) When the output is SOL, fills pay native SOL straight to the maker (no ATA needed).
+
+### Cancel / close
+
+1. If SOL input: ATA `create_idempotent` wSOL ATA (owner user). Otherwise ATA `create_idempotent` for the input mint ATA (owner user).
+2. Limo `close_order_and_claim_tip`. Accounts: maker (signer), order (writable, closed to maker), global_config, pda_authority, input_mint, output_mint, maker_input_ata, input_vault, input token program, system program, event authority, program. On chain: returns `remaining_input_amount` from the vault to maker_input_ata, pays `tip_amount` lamports from pda_authority to the maker, closes the order account and refunds its rent to the maker. Fails if `now < last_updated_timestamp + order_close_delay_seconds` (0 on prod now), if the order is in a flash operation, or if status is already Cancelled.
+3. If SOL: Token `close_account` of the wSOL ATA to user (unwraps).
+
+- For a filled order the maker's output has ALREADY been paid at fill time (to the maker's output ATA, or native SOL). Closing only returns leftover input, the tips, and rent. Filled orders stay as 424-byte accounts (22,375 of 22,739 prod order accounts are status Filled) until the maker closes them, so the app should offer "close" for filled orders to recover 0.00384 SOL plus tips.
+
+### What the pre-sign decoder should verify (create)
+
+Existing policy shape `programs: {id: {discriminators}}`, `mayWrapSol` fits. Additional checks needed because limo is not a token transfer the current code understands:
+
+- Program allow-list: Limo `LiMoM9...`, System, Token (or Token-2022), ATA, ComputeBudget. Nothing else.
+- Limo create_order: decode the data and require input_amount == requested raw amount, output_amount == requested raw output (price = output/input, check both), order_type == 0.
+- Account checks on that instruction: maker == the signer/owner; global_config == `prod7Mog8...` (pin it; a different config means a different admin and filler set, and a hostile config could hold or block funds); pda_authority == PDA(["authority", globalConfig]); input_vault == PDA(["escrow_vault", globalConfig, inputMint]); maker_ata == the owner's ATA for inputMint; input_mint and output_mint == the requested mints; token programs match the mints' owners; order account == the key of the extra order signer and is the account created by the create_account instruction (space 424, owner Limo, lamports 3,841,920 +/- config, payer = user).
+- Other instructions: System `transfer` only to the user's own wSOL ATA, amount <= input amount (the existing wrap check); no System transfer to any other address except the global-config fee transfer which happens inside the Limo CPI (so it will not appear as a top-level instruction; cap it by simulating, or by reading global_config `txn_fee_cost + ata_creation_cost` and bounding the user's SOL loss to input + rent + fee). Token `close_account` destination must be the user. ATA creates must have owner = user (or the user's own key). No Token `approve`, `set_authority`, or `transfer` to third parties.
+- Optional update_order: allow only mode 0 with value 1 (permissionless) if we ever enable it; refuse mode 1 (counterparty) unless we set it intentionally.
+- Order keypair: the tx has two signers (user + order key); the existing check that only the user must sign needs an exception for exactly one fresh ephemeral signer that is the new order account. The server must hold that key only for the signing step (or generate it client-side) and it holds no value.
+- Verify the price: the dapp should decode and show input mint/amount, output mint/min amount, and the implied price from the two u64s, using mint decimals from chain.
+
+### What to verify (cancel)
+
+close_order_and_claim_tip: maker == user; order account is one the app read from chain with `maker == user` (fetch and compare; the program enforces has_one maker, so a wrong order simply fails); maker_input_ata is the user's own ATA (token::authority = maker is enforced on chain, but check anyway); pda_authority and vault PDAs as above; global_config pinned; no extra transfers.
+
+## 3. Fill behaviour
+
+- Fillers: the order is filled by "searchers" in an auction; the winner pays a SOL tip to the trader (docs, kamino.com/docs/products/swap/limit-orders). Kamino charges no platform fee. Mainnet global config: `host_fee_bps = 0` (verified on chain), so no protocol cut either; tip lamports sit in pda_authority and are paid to the maker on close.
+- Third-party orders are filled only by the permissioned path unless the maker opts in: `take_order` requires `order.permissionless != 0` OR a valid Pyth Express Relay (PER) permission in the same tx (`check_permission_and_get_tip`). `create_order` sets `permissionless = 0` and `counterparty = default`. Verified via on-chain scan of the prod config: 22,726 of 22,739 orders have permissionless = 0 and 13 have it = 1. So normal orders created by anyone (any frontend, including ours) are eligible for PER searchers; there is no host/referrer allow-list in the program for makers, so third-party-created orders are treated the same as Kamino-UI ones. The program has no whitelist of maker or frontend. Whether PER searchers fill every pair or only the liquid ones is up to them (UNVERIFIED beyond the stats below).
+- Partial fills: yes. `take_order(input_amount, min_output_amount, tip)`; the taker may fill any `input_amount <= remaining`, and must pay at least `ceil(input * expected_output / initial_input)` (pro rata, rounding up in the maker's favour). Never worse than the stated price.
+- Expiry: none. The order account has no expiry field. It stays until filled or the maker cancels (docs say the same). Our UI must make that visible.
+- Minimum size: none in the program (only input_amount > 0, output_amount > 0, different mints). Practically, searchers need the fill to beat tip + fees, so dust may never fill (UNVERIFIED).
+- Fees paid by the maker: 0.003 SOL per order (txn_fee_cost) plus 0.00384 SOL refundable order rent plus signature/priority fee, plus a one-time vault rent if the input mint has no vault.
+- Tips / global config: no tip required from the maker; the global config is needed as an account input (pin `prod7Mog8...`); the maker cannot pay a tip. Searchers pay the tip.
+- Pairs observed on prod (open + filled-not-yet-closed order accounts, 22,739 total): USDC->SOL 7,814; SOL->USDC 6,780; USDC->USDT 1,394; USDT->USDC 1,172; USDT->SOL 693; USDC->cbBTC-like mint(cbbt...) 688; SOL->USDT 345; SOL->J1to(JitoSOL) 284. Status: 22,375 filled, 364 active. A 98% filled share of surviving accounts suggests these majors do fill; but filled orders linger while cancelled ones are deleted, so this is survivorship-biased and says nothing about price distance or time-to-fill. UNVERIFIED for long-tail pairs; we should restrict to SOL/USDC/USDT and a few majors.
+
+## 4. On-chain facts (read-only RPC)
+
+- Program `LiMoM9...` is deployed, executable, owner BPFLoaderUpgradeable. ProgramData `Eqay3PwNFLH7C2MSSsrZashRbzu2CBGCVMYr3zttM4sQ`, last deployed slot 446,205,635 = 2026-09-11 16:45 UTC (so the public GitHub source, last commit 2025-11-26, is behind the deployed binary).
+- Upgrade authority: `E4NYRj51oRgZpVNJFhX8fF7KThy3ukwd57Tc31iQ8rCs` (system-owned, 0 data; same key is the global config `admin_authority`). It is upgradeable, so Kamino can change program logic at any time. Whether this is a Squads vault/multisig is UNVERIFIED (a system-owned PDA is consistent with a Squads vault but not proof).
+- Global configs under the program: 6 (TeStcU..., prod7Mog8r56sn5dPwze8nVdf94veEawdxNNqd5v7A1, 3Lvo5g..., 98JtHV..., FVVFqi..., Fankws...). The `prod7Mog8...` one has emergency_mode 0, flash_take_blocked 0, new_orders_blocked 0, orders_taking_blocked 0, host_fee_bps 0, order_close_delay 0, txn_fee_cost 3,000,000, ata_creation_cost 0, total_tip_amount 95.2 SOL-equivalent lamports 95,206,476,055 and pda_authority balance 95.22 SOL. The admin can flip emergency mode or block new orders or order taking; funds stay in vaults (the admin has no instruction to sweep maker input from the vault: `withdraw_host_tip` only moves host tips).
+- Recent activity: the latest 1,000 signatures span 2026-11-04 13:41 to 2026-11-05 12:03 UTC (about 40 txs/hour at minimum; 32 of 1,000 failed). Actively used.
+- Audits (listed on kamino.com/docs/security/audits, web search snippet only; I did not open the report PDFs, so scope and findings UNVERIFIED): OtterSec 2024-11-07, Offside Labs 2024-11-29, Sec3 2025-01-29, Certora formal verification 2025-02-21 or 2025-05-13 (docs disagree). Bug bounty stated as $1.5M. These pre-date the current binary (Sept 2026 upgrade, newer fee_paid and RFQ venue code), so the deployed version is not fully covered by the dated audits as far as I can tell. Incidents: none found in a quick search; I did not do a deep incident search.
+
+## 5. Verdict
+
+Buildable, yes, non-custodial and kit-native. Estimated work: build the create/cancel/close instructions (SDK `*Ix` functions or a small hand-written kit builder), add an assert-safe policy for Limo, read orders by maker, UI for open/partially filled/filled-unclosed orders.
+
+Main risks:
+
+1. Funds sit in a Kamino PDA vault under an UPGRADEABLE program controlled by one non-program-verified key. A malicious or buggy upgrade could affect all escrowed input. Audits predate the latest binary.
+2. No expiry and no guaranteed filler. Order stays open until the price is hit and a searcher wants it; the person must cancel to get funds back, and dust or off-market orders may never fill. Permissionless is off by default, so only Pyth Express Relay searchers can fill (verified from source and chain).
+3. Cost: 0.003 SOL non-refundable (probably) per order, plus 0.00384 SOL rent refunded only after the user closes the order (including after fill), plus one-time vault rent for new input mints.
+4. Missing output ATA (SDK does not create it): add an idempotent ATA create or fills can fail.
+5. SDK hygiene: exact-pinned kit 8.3.0 vs our 8.6.0, anchor 0.28 and web3.js v1 pulled in, SDK README stale; the public program source is older than the deployed binary, so source reading is not a full guarantee of behaviour.
+6. Wrong global config is the main injection vector: the SDK takes it as input; pin `prod7Mog8...` in assert-safe.
+
+What a person can lose: the escrowed input amount in the worst case (program upgrade bug or exploit, or a pause that traps funds if admin disables closing; no close-blocking flag was seen in config, only new orders and order taking can be blocked); 0.003 SOL fee per order; an order filled at exactly their limit (no price improvement guaranteed, though the searcher tip adds a little SOL); and the rent of filled orders if they never close them. They cannot lose more than the escrowed input plus fee, because the tx is signed by the user and the output is paid pro rata at the stated price by program checks.

+# Sui limit orders on DeepBook V3 - research (2026-11-05)
+
+Verdict: BUILDABLE on DeepBook V3, one signature to open and place, with a custom tx builder and a new safety policy. Cetus limit orders are a worse fit (see 6). Funds are never held by us; they sit in a BalanceManager the person owns, and unfilled or filled tokens need an explicit withdraw to return to the wallet.
+
+Evidence legend: [SRC] read from SDK/Move source, [LIVE] queried read-only today, [DOC] docs page, [UNVERIFIED].
+
+## 1. Package, calls, flow
+
+Package: `@mysten/deepbook-v3` 2.10.1 (modified 2026-11-03), repo MystenLabs/ts-sdks, peer dep `@mysten/sui ^2.39.0` [LIVE npm]. Repo pins `@mysten/sui` 2.31.2 (apps/dapp/package.json), so a bump is required. SDK is by Mysten Labs (the protocol author), deps are only axios, @mysten/bcs, axios-retry, @noble/hashes. No postinstall seen in package.json scripts reviewed (I did not audit dist for supply-chain; a Socket listing exists for an older experimental version - UNVERIFIED relevance). Server-safe: it only builds `Transaction` fragments and calls a public indexer; nothing signs. Recommended: do NOT use the SDK client class at runtime on the server for the safety path; use it (or its generated `contracts/deepbook/*` bindings) only to build, and verify bytes independently.
+
+Mainnet ids [SRC src/utils/constants.ts]:
+
+- DEEPBOOK_PACKAGE_ID (core v9, latest, what calls target): `0xbca0cefe720330e7bb4f2283438b68de6a0e656688db4ac90d61e71fe6151fe8`
+- Types live in original package `0x2c8d603bc51326b8c13cef9dd07031a408a48dddb541963357661df5d3204809` [LIVE pool object type]. Dynamic fields show `0x00c1a56e...::ewma` and `::pool::ReferralRewards`, i.e. a middle version also appears in types. Policy must allow the latest id only and be updated on upgrade (fits safety.ts "unknown id refused" design).
+- REGISTRY_ID `0xaf16199a2dff736e9f07a845f23c5da6df6f756eddb631aed9d24a93efc4549d`; DEEP coin `0xdeeb7a46...c270::deep::DEEP`; USDC `0xdba34672...00e7::usdc::USDC`.
+- Package ids are NOT the same as the pool id; the pool is a shared object.
+
+Calls (SDK method -> Move target) [SRC transactions/balanceManager.ts, deepbook.ts; Move pool.move main]:
+
+1. Create: `balance_manager::new()` returns BalanceManager (SDK `createAndShareBalanceManager` does `new` then `0x2::transfer::public_share_object<...::balance_manager::BalanceManager>`). Variant `createBalanceManagerWithOwner(owner)` -> `balance_manager::new_with_custom_owner`.
+2. Deposit: `balance_manager::deposit<T>(manager, coin)`; SDK builds the coin with `coinWithBalance`, which emits SplitCoins/MergeCoins and, for address-balance funds, `0x2::coin::redeem_funds` etc. (the repo already allows these in safety.ts FRAMEWORK_CALLS).
+3. Proof: `balance_manager::generate_proof_as_owner(manager)` -> TradeProof (hot potato-like, needed by every trade call).
+4. Place: `pool::place_limit_order<Base,Quote>(pool, manager, proof, client_order_id u64, order_type u8, self_matching u8, price u64, quantity u64, is_bid bool, pay_with_deep bool, expire_timestamp u64, clock 0x6)`. SDK defaults: order_type NO_RESTRICTION, expiry MAX_TIMESTAMP, payWithDeep true. For a maker-only intent use POST_ONLY order_type; for no-surprise-fill use expiry.
+5. Cancel: `pool::cancel_order(pool, manager, proof, order_id u128, clock)`; also `cancel_orders`, `cancel_all_orders`, and `cancel_orders_permissionless`-style variants exist. Cancel settles the unfilled funds back to the manager balance (process_cancel -> settle_balance_manager) [SRC pool.move:596-617].
+6. Withdraw: `balance_manager::withdraw<T>(manager, amount)` or `withdraw_all<T>(manager)` returns Coin<T>, then `TransferObjects` to the person. Note the SDK's `withdrawFromManager` takes a `recipient` argument - the safety policy must pin it to the account.
+7. Read open orders: dry-run `pool::account_open_orders(pool, manager)` -> vector<u128>; `pool::get_order`, `get_orders`, `account(pool, manager)`; or indexer REST `https://deepbook-indexer.mainnet.mystenlabs.com/order_updates/SUI_USDC`, `/trades/SUI_USDC` (fills: price, base_volume, maker_balance_manager_id, fees) [LIVE]. Balance: `balance_manager::balance<T>`.
+
+One signature? Yes, with a caveat. Create + deposit + place can be one PTB, but a shared object cannot be shared and then referenced by ID in the same tx, and the SDK helpers all take a manager ID from config (`getBalanceManager(key).address`). So for first-time setup you must: `new` -> use the returned result argument directly in `deposit`, `generate_proof_as_owner`, `place_limit_order` -> `public_share_object` LAST. That means calling the generated move-call bindings (`balanceManagerMoveCalls`, `poolMoveCalls`) directly with the result handle, not the config-key helpers. This is plausible per Move rules (the object is owned by the PTB until shared) but I did NOT dry-run it - UNVERIFIED; test it with `simulateTransaction` (read-only) before building on it. Returning users (manager exists): deposit + proof + place is one PTB with the manager by ID.
+
+Correction, 5 November 2026: a maker's fill does not reach the BalanceManager by itself. It waits in the pool's record for the manager (`Account.settled_balances`) until the manager next acts on the pool or `withdraw_settled_amounts` runs, so `withdraw_all` alone returns nothing for it. Shown by simulation in `sui-deepbook.live.test.ts`. The next sentence holds for a taker.
+
+After a fill: a fill settles into the BalanceManager (process_create returns settled/owed, vault.settle_balance_manager) - the bought tokens are credited to the manager's balance, NOT the wallet. Person must call withdraw (second signature) to get tokens back; also true after cancel and expiry. There is a permissionless `withdraw_settled_amounts_permissionless` that credits maker proceeds to the manager (anyone can call it) but it still ends in the manager; only `withdraw` sends to the wallet and requires the owner [SRC pool.move]. Practical flow: place (sig 1) -> wait/monitor -> `withdraw_all` base+quote, in one PTB (sig 2). If cancelled: `cancel_order` + `withdraw_all` in one PTB (one sig). Optionally pre-add the withdraw in a later PTB; there is no auto-withdraw, no keeper.
+
+## 2. Pools, sizes, fees, prices
+
+Pools are shared objects, keyed by (Base,Quote). Mainnet ids [SRC constants.ts mainnetPools; matched against indexer get_pools LIVE]:
+
+- SUI_USDC `0xe05dafb5133bcffb8d59f4e12465dc0e9faeaa05e3e342a08fe135800e3e4407`

+- USDSUI_USDC `0xa374264d43e6baa5aa8b35ff18ff24fdba7443b4bcb884cb4c2f568d32cdac36`
+  Discover all via indexer `GET /get_pools` [LIVE]. Quote is USDC or SUI, so only pairs that exist are tradable; a SUI->USDC sell is the `isBid=false` order on SUI_USDC; a USDC->SUI buy is `isBid=true`.
+
+Validation (order*info.move validate_inputs) [SRC]: quantity >= min_size (EOrderBelowMinimumSize), quantity % lot_size == 0 (EOrderInvalidLotSize), price % tick_size == 0 and within range (EOrderInvalidPrice). Quantity is in base raw units. On-chain price = human price * 1e9 \_ quoteScalar / baseScalar (SDK convertPrice [SRC conversion.ts]); for SUI/USDC that is price \* 1e6.
+
+Live on-chain values for SUI_USDC via read-only simulate of `pool::pool_book_params` / `pool_trade_params` / `mid_price` / `whitelisted` [LIVE, my script scratchpad/di.mjs]:
+
+- tick_size 10 (raw) = 0.00001 USDC; lot_size 100000000 = 0.1 SUI; min_size 1000000000 = 1 SUI.
+- WARNING: indexer `/get_pools` reports tick_size 100 for SUI_USDC, which disagrees with the chain (10), and live book prices have 5 decimals (0.92059), consistent with 10. Do not trust the indexer for sizing; read chain.
+- trade params: taker fee 200000 (1e9 scale) = 2 bps, maker fee 0, stake_required 100000000000 = 100,000 DEEP. Not whitelisted (so DEEP fee or input-token fee applies). Per docs the whitelisted pools (DEEP_SUI, DEEP_USDC) are 0 fee [DOC docs.sui.io/standards/deepbookv3/design].
+- Other pools (indexer, units may be off as above, verify on chain): DEEP_USDC min 10 DEEP lot 1 DEEP tick 10000; XBTC_USDC min 1000 lot 1000 (8 decimals) tick 1e7; WAL_USDC min 1 WAL lot 0.1 WAL; DEEP_SUI min 10 lot 1.
+- Mid price: dry-run `pool::mid_price(pool, clock)`; returned 918740 = 0.91874 USDC [LIVE]. Alternatively indexer `/orderbook/SUI_USDC?level=1&depth=1` gave best bid 0.92106 / ask 0.92143 at fetch time; mid = (bid+ask)/2. Last trade ~0.92126.
+
+Fees and DEEP: place_limit_order has `pay_with_deep`. Move doc comment says "For current version pay_with_deep must be true", but the code path for false exists (empty deep price, input-token fee; `get_quantity_out_input_fee`, `can_place_limit_order` input-fee paths) [SRC pool.move:178, :1996-2010]. Whether false is actually accepted by deployed v9 for non-whitelisted pools is UNVERIFIED - dry-run to find out. If true, the BalanceManager must hold DEEP for taker fees on any part that crosses; a maker-only (POST_ONLY, resting) order that never takes pays maker fee 0, but the book still reserves DEEP for fees owed at place time per DEEP price. Needs DEEP deposit in practice -> a real onboarding burden. Use `get_order_deep_required` to compute. Live fills show `taker_fee_is_deep: true` and tiny fees (0.1057 DEEP for $16.76 trade).
+
+## 3. Safety check before signing (what assertPtbSafe needs for DeepBook)
+
+Repo state [SRC apps/dapp/lib/chains/sui/safety.ts, policies.ts]: `assertPtbSafe(payload, account, policy)` parses BCS, checks sender and gas owner = account, rejects non-Sender FundsWithdrawal, allows only SplitCoins/MergeCoins/TransferObjects (recipient pinned to me)/MoveCall in an allow-list of exact `pkg::module::function`, and routes each call to `policy.checkCall(call, readPure, account)`. Venues in policies.ts: springsui, cetus, navi. DeepBook appears only in venues.ts. A new `DEEPBOOK_POLICY` is needed. Note `public_share_object` and `new` are not in FRAMEWORK_CALLS: add exact `0x2::transfer::public_share_object` only with type arg pinned to `<DEEPBOOK_PKG or original>::balance_manager::BalanceManager` (do not allow the generic framework module; it can share anything).
+
+Allowed calls (latest pkg `0xbca0cefe...`): `balance_manager::{new, deposit, withdraw, withdraw_all, generate_proof_as_owner}`, `pool::{place_limit_order, cancel_order, cancel_orders, cancel_all_orders}`, `0x2::clock` by shared object 0x6. Do NOT allow `mint_trade_cap`, `mint_deposit_cap`, `mint_withdraw_cap`, `register_balance_manager`, `set_owner`/`new_with_custom_owner`, or any `*_cap`: those hand control of the manager to another address.
+
+checkCall must verify, from literal Pure inputs (reject anything not a Pure input, as `ReadPure` already does):
+
+- pool: the pool object input id equals the expected id from our own table for the asked pair AND type arguments equal [Base,Quote] for that pair (typeArguments exactly; a wrong type argument pair aborts, but a wrong pool with right types is a different-market risk e.g. a look-alike). Pool object must be the shared input with the expected id; since ids come through `Input` Object not Pure, readPure cannot read them - need an object-id check (data.inputs[n].UnresolvedObject/SharedObject.objectId); extend the policy API (current `ReadPure` only reads Pure).
+- side: is_bid (Pure bool) equals the asked side.
+- price: u64 equals expected raw price, computed by us from the human price with ticks (`price % tick == 0`, rounded in the person's disfavour never in ours), and within a sanity band of live mid (for example limit within a stated percent, or at least warn if a sell is far below mid / buy far above mid = would fill immediately at a worse price than asked; do cap it, since a limit order that crosses the book is a market order).
+- quantity: u64 equals asked base raw amount, multiple of lot_size, >= min_size.
+- order_type, self_matching, expiry (u64 ms): order_type pinned (POST_ONLY or NO_RESTRICTION as product decides), expiry within allowed window; `pay_with_deep` matches the fee mode we funded.
+- deposit: the Coin argument must come from our SplitCoins with amount equal to quantity (sell: base qty; buy: price\*qty in quote plus fee margin). Verify the SplitCoins amount Pure equals the expected deposit and coin type = expected. The balance manager argument for deposit/proof/place must be the SAME handle (result of `new`, or the person's known manager id). If an existing manager id is used, verify on chain that it exists, is a BalanceManager, and `owner == account` (read via GraphQL object), because depositing into a manager owned by someone else is a theft vector. For `new` in the same PTB the owner is ctx.sender, i.e. the account (new_with_custom_owner must be refused).
+- withdraw: `withdraw`/`withdraw_all` result must flow only into a TransferObjects whose recipient == account (already enforced) and amount ok. Cancel: order_id plausible and the manager is the person's.
+- No extra commands: default branch already refuses anything unknown (MakeMoveVec, Publish, Upgrade, etc.).
+- After build, re-run on the signed bytes (as the repo already does) and simulate (`simulateTransaction`) to assert balance changes: person's sell-token decreases by exactly deposit amount, nothing else leaves. The DeepBook move-call-level check alone cannot see value flow.
+
+Hard check on clientOrderId and DEEP: client_order_id is harmless. Gas: SDK sets a fixed gas budget constant; the repo's own flow should set it.
+
+## 4. Is it live
+
+- Mainnet package ids above; core v9 live [SRC + LIVE: calls to `pool_book_params` etc. at `0xbca0cefe...` succeeded in simulation today].
+- SUI/USDC 24h (indexer `/summary`, fetched 2026-11-05) quote volume about $4.55M, 4.89M SUI, last 0.92126, top-of-book spread 0.92106/0.92143 (about 4 bps), 1.5% 24h change [LIVE]. Orderbook depth at top about 2.2k SUI per side, level-2 about 1-4k SUI: thin; sizes of a few hundred SUI are fine, five-figure SUI will move the price [LIVE]. Other pools: DEEP_USDC ~$112k/24h, XBTC_USDC ~$1.0M, USDSUI_USDC ~$0.73M; WUSDT_USDC, TYPUS_SUI zero volume [LIVE]. Many pools are dead.
+- Audits: OtterSec is listed (third-party database) as auditing DeepBook V3, April 2025; report contents not seen; earlier OtterSec findings on the first DeepBook (Aug 2024) include a high "trade proof bypass" [UNVERIFIED, secondary source: movemaverick.github.io vulnerability database; OtterSec index https://ottersec.notion.site/Sampled-Public-Audit-Reports-a296e98838aa4fdb8f3b192663400772]. deepbookv3 repo has no `audits` folder (GitHub API 404) and a SECURITY.md [LIVE]. I found no MoveBit audit of V3.
+- Incidents: none found for DeepBook V3 in a web search (UNVERIFIED negative; search was shallow). The separate Cetus exploit (May 2025, about $220-260M) is unrelated to DeepBook.
+- Who can upgrade [LIVE, 5 November 2026]: `UpgradeCap` `0xdadf253c...4483`, policy 0 (compatible), held by `0x37f187e1...64d2`; the version 9 upgrade `3y8CSAfc...TLG7` carries a multisig signature (flag 3). The Move source sets no policy and the chain doesn't say whose keys those are. deepbook.xyz names the DeepBook Trading Foundation, and the code is in MystenLabs' repo [DOC].
+- Upgrade cadence is high (core v9, margin v8, SDK changelog shows many id bumps), so the allow-list needs a maintained pin and an alarm when the registry's allowed version changes. `EPackageVersionDisabled` (error 11) aborts old package calls after governance disables a version.

+
+## 6. Cetus limit orders (brief)
+
+- Product: on-chain limit order, default 7-day expiry up to one month, unfilled returned at expiry, filled tokens auto-sent to wallet, partial fills held on chain until claimed [DOC https://cetus-1.gitbook.io/cetus-docs/guides/how-to-place-a-limit-order]. SDK `@cetusprotocol/limit-sdk` 1.2.6 exposes place_limit_order, cancel_order, claim_target_coin (grep of dist/index.js); I found no user-callable fill/execute function in the SDK.
+- Who executes: not documented. Docs say orders run "when the price is triggered"; with no public fill entry point in the SDK, execution is almost certainly by Cetus-operated off-chain keepers/bots (inference, UNVERIFIED). That adds a trust and liveness dependency on Cetus (orders may not fire; they cannot be filled by the open market the way a resting DeepBook order can), and prices may fill at Cetus AMM prices with slippage rather than book prices.
+- DeepBook is a true on-chain CLOB: resting orders fill whenever any taker crosses, no keeper. Better for "non-custodial, we only build a tx" because no operator can fail to execute. Cetus' upside: tokens auto-delivered to wallet (no second withdraw), no BalanceManager and no DEEP. Downside: opaque executor and weaker evidence base. Recommendation: DeepBook for fidelity to a limit price; Cetus only if the second-signature/DEEP friction proves too heavy, after reading its contract source and package ids (not done here).
+
+## 7. Verdict, risks, what a person can lose
+
+Buildable: yes. Not tested end-to-end (no wallet, no tx submitted).
+
+Main risks:
+
+1. BalanceManager custody model: funds sit in a shared object whose ownership is the person's address. Wrong-manager deposit (not owned by them) or a minted TradeCap/DepositCap/WithdrawCap held by another party loses funds. Mitigation: owner check on chain, ban cap calls.
+2. Shared-object-in-same-PTB behaviour for create+deposit+place is unproven; fallback is two signatures for first use.
+3. DEEP fee requirement: `pay_with_deep` documentation says must be true; people without DEEP could see aborts or have to buy DEEP. Dry-run `pay_with_deep=false` before promising an input-fee path.
+4. Order crosses the book: a buy limit above ask fills at once as taker at market (up to 2 bps taker fee plus slippage on thin book); POST_ONLY avoids it but aborts/rejects if it would cross.
+5. Indexer data can disagree with chain (tick_size 100 vs 10). Chain is the source of truth for sizing.
+6. Thin liquidity beyond about 2-4k SUI per level; fills may be partial and rest for a long time; stale price risk (a resting order can fill into a market move; expiry mitigates). Dust sizes: min 1 SUI.
+7. Package upgrades: pins go stale; a new package id blocks the venue until reviewed (safe failure per safety.ts).
+8. Smart-contract risk: audit evidence only secondary; earlier DeepBook had a trade-proof bypass finding (fixed per V3 audit? UNVERIFIED).
+9. Two-signature exit: tokens stay in the manager until the person withdraws. UX must show "ready to withdraw" and never leave it implied they are in the wallet.
+
+What a person can lose: worst case, the full deposited amount if the manager owner/caps are wrong or the contract has a bug; in normal use, taker fee on crossing size (2 bps plus DEEP purchase cost), slippage if the order crosses, plus gas for the extra withdraw signature; unfilled funds are not lost, they are recoverable by cancel+withdraw at any time without a counterparty (nobody else can cancel). Exchange-rate risk while waiting is inherent to a limit order.

+# Agent Competition on Every Chain Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** A swap, supply or stake typed on NEAR, Solana, Sui, Avalanche or Monad runs the same agent competition as Stellar, and the winning plan is signed through that chain's existing safety checks.
+
+**Architecture:** `/api/agents/compete` gets a second branch for non-Stellar chains. It takes a `ChainActionRequest` rather than a `ParsedIntent`, asks a per-chain `quoteChainRoutes()` for priced routes, and streams the same frames, so the panel is unchanged. A route's `quote` is `{ kind: 'chain', request, venueId }`. Review calls the existing `chainAction.prepare`, so `assertSafe`, signing and submit all apply. Avalanche and Monad gain a `ChainModule` with one venue, 1Click.
+
+**Tech Stack:** Next 15, TypeScript, vitest, viem and wagmi, NEAR Intents 1Click REST.
+
+**Spec:** None written. The requirement is the user's "agentic competition on all chain" (2026-11-04). The research is in this plan's Facts section.

+
+## Global Constraints
+
+- Stellar's competition, swap, sequence and limit paths do not change. Every new branch tests `chain !== 'stellar'`.
+- No edits to `components/intents/naira-payout-card.tsx`, `bank-picker.tsx` or `hooks/use-naira-payout.ts`.
+- Agents choose a route id only. They never supply an amount, a recipient or a token (`tool-schema.ts` already has none).
+- Race quotes must be `dry: true`. A deposit address is created only when the user presses Review. One press, one address.
+- Every signed payload goes through `prepareChainAction` and then `venue.assertSafe`. Chain routes must never reach `useSwapExecution`.
+- One route still races, as the user asked, and the panel says "One route available on {chain}. The agents are judging whether it's worth taking."
+- On non-Stellar chains `executionMode` is forced to `fill`, `thenAction` to `none`. `rest` and `split` are not offered.
+- No new dependencies. Commit subjects lowercase, header at most 100 characters, no co-author lines, no attribution footer.
+- Disk is nearly full (about 7 GB free): do not start a second dev server or `next build`. Use vitest and `tsc --noEmit`.
+- Work on a new branch `feat/agents-every-chain`, created from `feat/multichain-wallet-gate` with `git switch -c`, which changes no files and leaves the user's dev server running.
+
+## Review Focus
+
+- A token the chain doesn't list, such as "swap 5 FOO to USDC" on Solana: no race, no agent calls, the existing refusal is shown. Tested in Task 1.
+- Quotes that all fail, such as 1Click down: agents are not called and the user sees a sentence. Tested in Task 1.
+- 66-character Sui addresses reaching the rate limiter: the account is kept, not dropped. Tested in Task 1.
+- Decimals of 6, 9, 18 and 24: the winner is the route with the better dollar output. Tested in Task 2.
+- A second Review press on a NEAR, Avalanche or Monad route: no second deposit address while the first is on screen. Tested in Task 4.
+

+
+### Task 1: Compete route takes a chain request
+
+**Files:**
+
+- Create: `apps/dapp/lib/agents/chain-routes.ts`
+- Modify: `apps/dapp/app/api/agents/compete/route.ts`
+- Modify: `apps/dapp/lib/chains/types.ts`
+- Test: `apps/dapp/lib/__tests__/agents-chain-compete.test.ts`
+
+**Interfaces:**
+
+- Produces: `interface ChainRouteQuote { kind: 'chain'; request: ChainActionRequest; venueId: string; venueName: string; pay: { amount: string; symbol: string }; receive?: { amount: string; symbol: string }; apyPercent?: number; valueInUsd?: number; valueOutUsd?: number }`
+- Produces: `quoteChainRoutes(chainApi: ChainModule, request: ChainActionRequest, account: string): Promise<QuotedRoute[]>`, with ids `${venueId}-1`, calling each usable venue's new optional `ChainVenue.quote`.
+- Produces: `ChainVenue.quote?: (request: ChainActionRequest, account: string) => Promise<VenueQuote>` and `VenueQuote = { receive?: { amount: string; symbol: string }; apyPercent?: number; valueOutUsd?: number }`.
+- Produces: compete body field `chainAction?: ChainActionRequest`.
+
+- [ ] **Step 1: Write failing tests**, with `chainModule` mocked: `chain: 'near'` with `chainAction` streams `competition:started`, not `chain_unsupported`; a body without `chainAction` on `near` gets `chain_unsupported`; a Stellar body takes the old path; an unknown token ends in `competition:error` with no `brain.propose` call; all quotes failing ends in `competition:error` with no `brain.propose` call; `account` of 66 characters reaches `enforceRateLimit`.
+- [ ] **Step 2: Run** `pnpm exec vitest run lib/__tests__/agents-chain-compete.test.ts` from `apps/dapp`. Expected: FAIL.
+- [ ] **Step 3: Implement.** Replace `EXECUTING_CHAINS` with a check that `chain === 'stellar' || chainModule(chain) !== undefined`. Raise the account limit to 128. Add a branch after the roster check that builds `market.routes` from `quoteChainRoutes`, skips `parseIntent`, `resolveAsset`, `fetchOrderBookTop` and `ensureLiveAssets`, and builds a minimal `ParsedIntent` via a new `intentFromChainAction()` so `brain.propose` and logging keep their types.
+- [ ] **Step 4: Run** the same command. Expected: PASS.
+- [ ] **Step 5: Commit** `feat(dapp): let the agent race take a chain action`.
+
+### Task 2: Prompts and scoring tell the truth per chain
+
+**Files:**
+
+- Modify: `apps/dapp/lib/agents/brief.ts`, `apps/dapp/lib/agents/brains/openai-compatible.ts:309,354,366`, `apps/dapp/lib/agents/market-context.ts:145,208`, `apps/dapp/lib/agents/measure.ts`
+- Modify: `apps/dapp/app/api/agents/compete/route.ts` (`measured`, `settlePlan`)
+- Test: `apps/dapp/lib/__tests__/agents-chain-prompt.test.ts`
+
+**Interfaces:**
+
+- Consumes: `ChainRouteQuote` (Task 1).
+- Produces: `systemPromptFor(chain: string): string`; `measureChainRoute(q: ChainRouteQuote): { outUsd: number; vsInPct: number } | undefined`; `settleChainPlan(p: AgentProposalResult): AgentProposalResult`.
+
+- [ ] **Step 1: Write failing tests:** the prompt for `near` contains neither "testnet", "anchor", "rest" nor "split"; for `stellar` it equals today's `SYSTEM_PROMPT`; `measureChainRoute` ranks $4.97 out above $4.74 out from quotes in 6, 9, 18 and 24 decimals; a proposal with `executionMode: 'rest'` and `thenAction: 'lend'` becomes `fill` and `none`; `buildMarketContext('solana')` offers only venues with `integration: 'executes'`, and no Stellar tokens.
+- [ ] **Step 2: Run** `pnpm exec vitest run lib/__tests__/agents-chain-prompt.test.ts`. Expected: FAIL.
+- [ ] **Step 3: Implement.** Supply and stake routes rank on `apyPercent`, using each venue's existing rate reader (`jupiter-lend.ts:140`, `kamino.ts:109`, `near/stake.ts:53`). Prices come from `chainApi.priceUsd`.
+- [ ] **Step 4: Run** the same command. Expected: PASS.
+- [ ] **Step 5: Commit** `feat(dapp): give agents each chain's own facts`.
+
+### Task 3: NEAR races (hackathon, ships first)
+
+**Files:**
+
+- Modify: `apps/dapp/lib/chains/near/swap.ts`, `apps/dapp/lib/chains/near/stake.ts`, `apps/dapp/lib/chains/near/earn.ts`
+- Test: `apps/dapp/lib/__tests__/near-race-quote.test.ts`
+
+**Interfaces:**
+
+- Consumes: `ChainVenue.quote` (Task 1).
+- Produces: `quote` on `oneClickVenue`, `metapoolVenue`, `rnearVenue`, `earnVenue`.
+
+- [ ] **Step 1: Write failing tests:** `oneClickVenue.quote` posts `dry: true` and returns `receive` and `valueOutUsd`; it runs `assertQuoteMatches`, reusing that check; it never reads `depositAddress`; each stake venue returns its `apyPercent`.
+- [ ] **Step 2: Run** `pnpm exec vitest run lib/__tests__/near-race-quote.test.ts`. Expected: FAIL.
+- [ ] **Step 3: Implement** by reusing `requestQuote` and the preview half of `prepareOneClickDeposit`.
+- [ ] **Step 4: Run** the same command. Expected: PASS.
+- [ ] **Step 5: Commit** `feat(dapp): quote near venues for the agent race`.
+
+### Task 4: The chat runs the race and Review signs the winner
+
+**Files:**
+
+- Modify: `apps/dapp/hooks/use-competition.ts`, `apps/dapp/components/intents/intent-chat.tsx` (the `parseChainAction` branch, `handleExecute`, `locked`), `apps/dapp/components/intents/competition-panel.tsx`, `apps/dapp/lib/orchestrate/capabilities.ts:11`
+- Create: `apps/dapp/lib/agents/chain-race.ts`
+- Test: `apps/dapp/lib/__tests__/agents-chain-race.test.ts`
+
+**Interfaces:**
+
+- Consumes: compete `chainAction` (Task 1), `ChainRouteQuote` (Task 1).
+- Produces: `chainRequestFor(route: unknown, asked: ChainActionRequest): ChainActionRequest | undefined`, which returns the request with `venue` set and refuses anything whose token or amount differs from `asked`.
+- Produces: `useCompetition` option `chainAction`, sent in place of `parsed`.
+
+- [ ] **Step 1: Write failing tests:** `chainRequestFor` sets `venue`; it returns undefined when a route's amount, `tokenIn` or `tokenOut` differs from `asked`; it returns undefined for a Stellar `SwapQuote`; `singleRouteNote(1, 'NEAR')` returns the Global Constraints sentence; `singleRouteNote(2, 'NEAR')` returns undefined; a second call while one prepare is pending does not call `prepare` again.
+- [ ] **Step 2: Run** `pnpm exec vitest run lib/__tests__/agents-chain-race.test.ts`. Expected: FAIL.
+- [ ] **Step 3: Implement.** In the chat, `parseChainAction` success starts the race rather than `chainAction.prepare`. `handleExecute` on non-Stellar calls `chainAction.prepare(chainRequestFor(route, asked), text)`. If the race ends in an error frame, call `chainAction.prepare(asked, text)` so the chain keeps working when agents are offline. Include `chainAction.phase` signing and submitting in `locked`.
+- [ ] **Step 4: Run** the same command and `pnpm exec tsc --noEmit`. Expected: PASS, exit 0.
+- [ ] **Step 5: Commit** `feat(dapp): run the agent race on near from chat`.
+
+### Task 5: Solana and Sui race, with 1Click as a second route
+
+**Files:**
+
+- Create: `apps/dapp/lib/chains/oneclick-origin.ts`
+- Modify: `apps/dapp/lib/chains/near/oneclick.ts` (`assetIdOf` by chain), `apps/dapp/lib/chains/solana/jupiter-swap.ts`, `solana/jupiter-lend.ts`, `solana/kamino.ts`, `solana/lulo.ts`, `solana/module.ts`, `sui/cetus.ts`, `sui/navi.ts`, `sui/springsui.ts`, `sui/module.ts`
+- Test: `apps/dapp/lib/__tests__/oneclick-origin.test.ts`, `apps/dapp/lib/__tests__/solana-sui-race-quote.test.ts`
+
+**Interfaces:**
+
+- Consumes: `solanaDeposit` and `suiDeposit` builders and asserters in `lib/weave/deposit/`.
+- Produces: `oneClickOriginVenue(chain: 'solana' | 'sui' | 'avalanche' | 'monad'): ChainVenue`, whose `prepare` takes a `dry: false` quote and builds one transfer to its deposit address, whose `assertSafe` admits only that transfer, and whose `submit` confirms it and follows `depositStatus`.
+- Produces: `oneClickAssetId(chain, token): Promise<string | undefined>` from `listTokens()`, matched on chain and contract, refusing a symbol match alone.
+
+- [ ] **Step 1: Write failing tests:** the Jupiter `quote` uses `/swap/v2/order` and returns `receive` without exposing `transaction`; the Cetus `quote` returns its best route; `oneClickAssetId` refuses a look-alike symbol on another contract; `assertSafe` refuses a wrong recipient, wrong amount and an extra transfer; a deposit memo is refused; a native SOL or SUI input is refused with a plain sentence, so only USDC and USDT reach 1Click in this task.
+- [ ] **Step 2: Run** `pnpm exec vitest run lib/__tests__/oneclick-origin.test.ts lib/__tests__/solana-sui-race-quote.test.ts`. Expected: FAIL.
+- [ ] **Step 3: Implement.** Generalise the deposit builders by passing the token rather than assuming USDC, keeping their tests green. Add the venue to `venues` in `solana/module.ts` and `sui/module.ts`. Add its row and logo per `feedback-always-add-venue-logos`, which `venue-logos.test.ts` enforces.
+- [ ] **Step 4: Run** the same command plus `pnpm exec vitest run lib/__tests__/weave-deposit`. Expected: PASS.
+- [ ] **Step 5: Commit** `feat(dapp): race jupiter and cetus against 1click`.
+
+### Task 6: Avalanche and Monad can swap, and race
+
+**Files:**
+
+- Create: `apps/dapp/lib/chains/evm/module.ts`, `apps/dapp/lib/chains/evm/tokens.ts`, `apps/dapp/lib/chains/evm/submit.ts`
+- Modify: `apps/dapp/lib/chains/types.ts` (`ChainWithActions`, evm `value`), `apps/dapp/lib/chains/registry.ts`, `apps/dapp/lib/chains/capabilities.ts`, `apps/dapp/lib/adapters/evm-adapter.ts` (Monad `signPrepared`, non-zero `value`), `apps/dapp/app/api/chain/[chain]/submit/route.ts` (`evm` in the union, family check), `apps/dapp/lib/__tests__/weave-deposit-avalanche.test.ts:512`
+- Test: `apps/dapp/lib/__tests__/evm-module.test.ts`
+
+**Interfaces:**
+
+- Consumes: `oneClickOriginVenue` (Task 5).
+- Produces: `avalancheModule`, `monadModule: ChainModule`, with tokens AVAX, USDC, USDT on Avalanche and MON, USDC, USDT0 on Monad, contract addresses read from 1Click's list and checked against `0xb97ef9ef8734...` for Avalanche USDC and `0x754704bc059f...` for Monad USDC.
+
+- [ ] **Step 1: Write failing tests:** `chainModule('monad')` and `chainModule('avalanche')` are defined; a native AVAX transfer payload passes `assertSafe` only with `value` equal to the quote's amount and empty `data`; an ERC-20 payload passes only with `value: '0'`; a Monad `chainId` of 143 is required, and 43114 is refused on Monad; the submit route accepts `{ family: 'evm', hash }` for both; a receipt from another account is refused.
+- [ ] **Step 2: Run** `pnpm exec vitest run lib/__tests__/evm-module.test.ts`. Expected: FAIL.
+- [ ] **Step 3: Implement.** Confirm Monad's chain id with `viem/chains` before writing it. Reuse the Avalanche deposit's receipt check for ERC-20 and write the equivalent for native.
+- [ ] **Step 4: Run** `pnpm exec vitest run lib/__tests__/evm-module.test.ts lib/__tests__/weave-deposit-avalanche.test.ts`. Expected: PASS.
+- [ ] **Step 5: Commit** `feat(dapp): swap and race on avalanche and monad through 1click`.
+
+### Task 7: Record which chain each race ran on
+
+**Files:**
+
+- Modify: `apps/dapp/lib/server/analytics.ts:65`, `apps/dapp/app/api/agents/history/route.ts`, `apps/dapp/app/api/chain/[chain]/submit/route.ts:73-80`
+- Create: `packages/db/migrations/014_agent_races_chain.sql`
+- Test: extend `apps/dapp/lib/__tests__/agents-chain-compete.test.ts`
+
+- [ ] **Step 1: Write failing tests:** `logRace` writes `chain`; the history route accepts a Solana, Sui, NEAR and EVM account rather than only `StrKey`; a chain submit carries the race id it came from.
+- [ ] **Step 2: Run** the test file. Expected: FAIL.
+- [ ] **Step 3: Implement,** with `ALTER TABLE agent_races ADD COLUMN IF NOT EXISTS chain TEXT NOT NULL DEFAULT 'stellar'` in both the migration and the code's DDL.
+- [ ] **Step 4: Verify the whole change.** Run `pnpm exec tsc --noEmit`, `pnpm exec next lint --quiet` and `pnpm exec vitest run --maxWorkers=4 --minWorkers=1`. Expected: exit 0 for the first two. The only failures allowed are live-network tests in code this plan doesn't touch, and each must be named in the report.
+- [ ] **Step 5: Commit** `feat(dapp): record the chain of every agent race`.
+
+## Not in this plan
+
+- Agents choosing limit orders, swap-then-deposit, or cash-out on these chains. They need those features to exist first.
+- A second swap venue on NEAR (Rhea needs `ft_transfer_call`, which `near/safety.ts:10` refuses), Avalanche or Monad (neither is covered by the integration report), so these three start with one swap route.
+- Native SOL and SUI through 1Click. Jupiter and Cetus still take them.
+- A real signed transaction: the user does that with a funded wallet. No agent in this plan may sign or send.

+# Multi-Step Transactions on Every Chain Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** On Solana, Sui, NEAR, Avalanche and Monad, a person can do what Stellar already does in one conversation: see everything their wallet holds, keep their chat, and run a swap followed by a cash-out, deposit, stake or send.
+
+**Architecture:** Stellar's `use-sequence.ts` is built on XDR, Horizon and anchors, so it is copied in behaviour, not reused. A new `useChainSequence` hook sits beside the existing `useChainAction` and `useCashout`: the race and signing for step 1 are unchanged, then the hook measures what actually arrived and hands that amount to step 2, which the person starts themselves. Balances gain a `ChainModule.balances` read behind one route. The chat stays mounted across pages by moving `IntentChat` into the chain layout, and a read-only transcript survives reloads.
+
+**Tech Stack:** Next 15, React 19, TypeScript, viem, vitest (node, no DOM). pnpm monorepo, app in `apps/dapp`.
+
+**Spec:** No design document: the person chose to skip it and said "build". What they asked for, from testing the preview on Solana:
+
+- "the AI can only read solana wallet balance and not all the tokens"
+- "first swap the sol to usdc then from usdc to fiat ... on all the chains not just stellar"
+- "except the chat session ends or user starts new chat the chat should always persists"
+- "Add each of the currency country logo"
+- "multilayered txns of swap first then offramp then to other thing, for all the chain"
+
+## Facts this plan rests on
+
+Checked live on 2026-11-04.
+
+- 1Click dry quotes to USDC work for SOL, AVAX and NEAR. **Every Monad-origin quote answers HTTP 400 "Internal server error"**, including ones that passed earlier the same day.
+- Solana listing: `solana-rpc.publicnode.com` refuses `getTokenAccountsByOwner` (403). `api.mainnet-beta.solana.com` answered for both token programs, from a home connection. Its limits from Vercel are untested, and `SOLANA_RPC_URL` is unset on Preview and Production.
+- Sui: `graphql.mainnet.sui.io` answers `address.balances`.
+- NEAR: `https://api.fastnear.com/v1/account/{id}/ft` lists every fungible token held, with raw balances.
+- EVM has no "all tokens" RPC, so Avalanche and Monad read known tokens only.
+- A Weave order sets `walletAddress` and `refundAddress` to the paying wallet on the deposit chain (`lib/weave/client.ts:312-335`). Paying from another chain would leave no valid refund address, so cross-chain cash-out is out of this plan.
+- Weave charges about 1% over the order amount. `lib/weave` accepts up to 2% over.
+- Weave on NEAR fails at the order step (`Incorrect depositMode`). Weave does not list Monad.
+- Weave institutions: UGX has two mobile money providers and no banks; KES and TZS have a mix; NGN has banks only.
+
+## Global Constraints
+
+- Stellar's behaviour does not change. Any Stellar regression is a defect, including its chat path, `use-sequence.ts` and its naira form.
+- Never edit `components/intents/naira-payout-card.tsx`, `components/intents/bank-picker.tsx` or `hooks/use-naira-payout.ts`. The cash-out form's layout stays as prod's.
+- An answer may lack `pending` only if it proves nothing moved. A step 1 that is `pending` or unknown never advances to step 2.
+- Nothing opens a wallet on its own. Step 2 starts only from a press by the person.
+- Step 2's amount is always measured from the chain, never taken from a quote, and never guessed when a read fails.
+- A follow-on that cannot run is refused before step 1 is signed.
+- No agent signs or sends. Dry quotes only in tests. No Weave order is created by any test or agent.
+- Agents pick route ids only. Nothing an LLM writes affects what is signed.
+- Client bundles import no server-only module or secret.
+- No module reads the Stellar network at import. Every task's focused run includes `import-purity` and `routes-load-with-two-networks`.
+- User-facing copy is true on every path it can appear on, plain, with no em dashes.
+- Every integrated app ships its real logo in the same change. Country flags are local files, not a CDN.
+- Commits: lowercase subject, header at most 100, body lines at most 100, no co-author line, no attribution footer. Stage named files only; never `.claude/`, `apps/dapp/.next-verify/` or `.env.local`.
+- No dev server: port 3001 is the person's. No `next build` on Windows. Do not switch branches.
+- vitest is node with no DOM and no BigInt literals, so logic goes in pure helpers under `lib/`.
+- Vitest flags: always `--maxWorkers=4 --minWorkers=1` or lower, never `--maxWorkers=1` alone.
+
+## Review Focus
+
+1. Spending a wallet's whole native balance ("offramp 0.01477 SOL" with 0.01477 SOL held): refused before signing, naming what can be spent. Test in Task 4.
+2. Step 1 answers pending, or the wallet reports an error after sending: step 2 is never offered, and the person is told to check before doing anything. Test in Task 5.
+3. Measuring what arrived fails or stays at zero: the person is told they hold the token and nothing was paid out, with no amount guessed. Test in Task 5.
+4. A different wallet connects between step 1 and step 2: step 2 refuses with the existing wrong-wallet sentence. Test in Task 5.
+5. A transcript restored after a reload holds nothing signable, and another wallet never sees it. Test in Task 3.
+

+
+### Task 1: Country logos and "mobile money" wording
+
+**Files:**
+
+- Create: `apps/dapp/public/flags/ng.svg`, `ke.svg`, `ug.svg`, `tz.svg`, `apps/dapp/lib/weave/currency-flag.ts`, `apps/dapp/lib/__tests__/currency-flag.test.ts`
+- Modify: `apps/dapp/components/intents/cashout-currency-question.tsx`, `apps/dapp/components/intents/cashout-card.tsx`
+
+**Interfaces:**
+
+- Produces: `currencyFlag(code: string): { src: string; country: string } | undefined`, `payoutWord(types: readonly string[]): 'bank' | 'mobile money provider' | 'bank or mobile money'`.
+
+- [ ] **Step 1: Write failing tests.** Each of NGN, KES, UGX and TZS returns `/flags/{ng,ke,ug,tz}.svg` and its country name, and the file exists under `public/flags`. An unknown code returns undefined. `payoutWord(['mobile_money','mobile_money'])` is `'mobile money provider'`, `['bank']` is `'bank'`, `['bank','mobile_money']` is `'bank or mobile money'`.
+- [ ] **Step 2: Run** `pnpm exec vitest run currency-flag`. Expected: FAIL.
+- [ ] **Step 3: Implement.** Take the four flags from the MIT-licensed `flag-icons` package's 4x3 SVGs, and copy the files in rather than adding a dependency. Show the flag before the name on each currency button and in the cash-out form's currency display. Where `cashout-card.tsx` itself writes "bank" for a non-naira currency, use `payoutWord` on the loaded institutions. If a sentence is hard-coded inside `bank-picker.tsx`, leave it and report it.
+- [ ] **Step 4: Run** the test file, `tsc`, then eslint. Expected: PASS.
+- [ ] **Step 5: Commit** `feat(dapp): show each payout currency's country flag`.
+
+### Task 2: Every token the wallet holds, read fresh
+
+**Files:**

+- Modify: `apps/dapp/lib/chains/types.ts`, each chain's `module.ts`, `apps/dapp/components/intents/intent-chat.tsx:1650-1654` and its call site
+
+**Interfaces:**
+
+- Produces in `lib/chains/types.ts`:
+
+```ts
+export interface TokenBalance {
+  symbol: string
+  id: string
+  amount: string
+  decimals: number
+  native: boolean
+  /** In this chain's token table. An unlisted token can't be traded here yet. */
+  listed: boolean
+}
+export interface WalletBalances {
+  tokens: TokenBalance[]
+  /** False when only known tokens could be read. */
+  complete: boolean
+}
+// ChainModule gains:
+balances: (account: string) => Promise<WalletBalances>
+```
+
+- Produces: `GET /api/chain/[chain]/balances?account=` answering `WalletBalances`, or 503 `{ error }`. Rate limited with `enforceRateLimit(request, 'build')`. A malformed account answers 400.
+- Produces: `chainBalanceReply(balances: WalletBalances | undefined, chainName: string): string`.
+
+- [ ] **Step 1: Write failing tests**, with fetch stubbed to real response shapes:
+  - Solana parses `getTokenAccountsByOwner` from both token programs plus `getBalance`, all with commitment `confirmed`. When listing is refused, it falls back to the token table with `complete: false`.
+  - Sui parses `address.balances`, and an unlisted coin's symbol is the coin type's last segment.
+  - NEAR parses the FastNEAR list, with a registry fallback and `complete: false` when it fails.
+  - EVM reads native plus each table token, always `complete: false`, and Avalanche never reads Monad's table.
+  - `chainBalanceReply`: native first, then listed, then unlisted with the shortened id (`AbCd…wXyZ`); zero balances dropped except native; over 30 tokens ends "and N more"; `complete: false` adds "Only tokens Intent knows on {chain} are shown."; `undefined` answers "I could not read your balance just now, so I won't guess. Try again in a moment." and no number.
+- [ ] **Step 2: Run** `pnpm exec vitest run chain-balances`. Expected: FAIL.
+- [ ] **Step 3: Implement.**
+  - Solana uses `SOLANA_RPC_URL`, else `https://api.mainnet-beta.solana.com`, on the server; never publicnode for listing.
+  - Sui takes decimals from GraphQL `coinMetadata`, and an unknown one leaves the token out rather than guessing.
+  - NEAR uses `https://api.fastnear.com/v1/account/{id}/ft`, with `ft_metadata` for at most 20 unlisted tokens.
+  - In the chat, the non-Stellar branch of `walletBalanceReply` becomes async and fetches this route at the moment of asking. Stellar's branch is untouched.
+- [ ] **Step 4: Run** the test file, `import-purity`, `routes-load-with-two-networks`, `tsc`, then eslint. Expected: PASS.
+- [ ] **Step 5: Commit** `feat(dapp): read every token a wallet holds on each chain`.
+
+### Task 3: The chat stays until New chat
+
+**Files:**
+
+- Create: `apps/dapp/components/intents/chat-host.tsx`, `apps/dapp/lib/chat/live-session.ts`, `apps/dapp/lib/__tests__/live-session.test.ts`
+- Modify: `apps/dapp/app/[chain]/layout.tsx`, `apps/dapp/app/[chain]/intents/page.tsx`, `apps/dapp/app/[chain]/intents/new/page.tsx`, `apps/dapp/components/intents/intent-chat.tsx`
+
+**Interfaces:**
+
+- Produces in `lib/chat/live-session.ts`:
+
+```ts
+export interface LiveTurn {
+  role: 'user' | 'agent'
+  text: string
+  explorerUrl?: string
+  at: number
+}
+export function liveSessionKey(chain: string, account: string): string
+export function loadLiveSession(
+  storage: Pick<Storage, 'getItem'> | undefined,
+  chain: string,
+  account: string
+): LiveTurn[]
+export function appendLiveTurn(
+  storage: Pick<Storage, 'getItem' | 'setItem'> | undefined,
+  chain: string,
+  account: string,
+  turn: LiveTurn
+): void
+export function clearLiveSession(
+  storage: Pick<Storage, 'removeItem'> | undefined,
+  chain: string,
+  account: string
+): void
+```
+
+- [ ] **Step 1: Write failing tests.** Two accounts or two chains never read each other's turns. The list caps at the newest 200. Broken storage or malformed JSON returns `[]` and never throws. Only `role`, `text`, `explorerUrl` and `at` are kept, with any other field dropped on load, so a saved entry cannot carry a signing payload, a route or a deposit address. `explorerUrl` must be `https:`, or it is dropped.
+- [ ] **Step 2: Run** `pnpm exec vitest run live-session`. Expected: FAIL.
+- [ ] **Step 3: Implement the mounted chat.** `ChatHost` is a client component in `app/[chain]/layout.tsx`, inside `ChainProvider`, keyed by chain. It renders the page header and `IntentChat` once a chain is open, and uses the `hidden` attribute when `usePathname()` is not `/{chain}/intents` or `/{chain}/intents/new`. The two page files stop rendering `IntentChat` and render nothing of their own beyond what they need. Keep whatever `intents/new` passes to the chat today. Because hooks stay mounted, a live race, card, latch and cash-out poll all survive navigation.
+- [ ] **Step 4: Implement the transcript.** The chat appends each message it shows from the person and each agent reply, chain race outcome sentence, and settled hash. On mount with no live thread, it shows `loadLiveSession` for the connected account above the composer as plain read-only bubbles, with no buttons. `newChat()` calls `clearLiveSession`. Wallet disconnect hides it and doesn't delete it. A chain race settles to one sentence naming venue and result. Do not add chain races to `saveTurn`.
+- [ ] **Step 5: Run** the test file, `import-purity`, `routes-load-with-two-networks`, `tsc`, then eslint. Expected: PASS.
+- [ ] **Step 6: Commit** `feat(dapp): keep the chat until a new chat starts`.
+
+### Task 4: Reading a multi-step request, and refusing what can't finish
+
+**Files:**
+
+- Create: `apps/dapp/lib/chains/sequence.ts`, `apps/dapp/lib/chains/parse-sequence.ts`, `apps/dapp/lib/__tests__/chain-sequence.test.ts`
+- Modify: `apps/dapp/lib/weave/parse-cashout.ts`, `apps/dapp/lib/weave/cashout-view.ts`, `apps/dapp/lib/chains/prepare.ts`, `apps/dapp/app/api/agents/compete/route.ts`
+
+**Interfaces:**
+
+- Produces in `lib/chains/sequence.ts`:
+
+```ts
+export type FollowOn =
+  | { kind: 'cashout'; currency?: CashoutCurrencyCode }
+  | { kind: 'supply' | 'stake'; venue?: string }
+  | { kind: 'send'; recipient: string }
+export interface ChainSequenceRequest {
+  swap: ChainActionRequest
+  followOn: FollowOn
+}
+export const SEQUENCE_CASHOUT_CHAINS: readonly ChainWithActions[] // solana, sui, avalanche
+export function deliveredAmount(

+export function followOnRefusal(
+  chain: ChainWithActions,
+  chainName: string,
+  followOn: FollowOn,
+  venues: readonly Pick<ChainVenue, 'kinds'>[]
+): string | undefined
+export function strandedReply(symbol: string, amount: string | undefined): string
+```
+
+- Produces: `parseChainSequence(text: string): ChainSequenceRequest | { refusal: string } | null`.
+- Produces in `lib/chains/prepare.ts`: `NATIVE_FEE_RESERVE: Record<ChainWithActions, string>` with `solana '0.005'`, `sui '0.05'`, `near '0.05'`, `avalanche '0.01'`, `monad '0.05'`, and `assertNativeReserve(chainApi: ChainModule, request: ChainActionRequest, account: string): Promise<void>`.
+- `CashoutRead`'s `unsupportedToken` form gains `amount?: string`. `CashoutRoute` gains `{ kind: 'sequence'; token: string; amount: string; currency?: CashoutCurrencyCode }`.
+
+- [ ] **Step 1: Write failing tests:**
+  - `parseChainSequence` reads each of these into the right swap and follow-on: "swap 5 SOL to USDC then cash out", "swap 5 SOL to USDC and cash out to kes", "swap 5 SOL to USDC then deposit", "swap 5 SOL to USDC then stake", "swap 5 SOL to USDC then send to {address}".
+  - "swap 5 SOL to BONK then cash out" gives `{ refusal }` saying cash-outs take USDC. "swap 5 SOL to USDC" returns null, since it is a plain swap. A plain deposit returns null.
+  - `routeCashout({ unsupportedToken: 'SOL', amount: '0.5' }, 'solana')` gives `kind: 'sequence'`. The same on `stellar` still gives `pass`. With no amount it stays `token`. On `near` it stays `token`, and `unsupportedTokenReply` says there what is true on NEAR. Monad stays `pass`.
+  - `deliveredAmount('1.5','6.5',6)` is `'5'`. Undefined on either side, or `after <= before`, gives undefined. It uses BigInt on base units, so `0.1 + 0.2` errors can't occur.
+  - `cashoutAmountFrom('5')` is `'4.9'` and `cashoutAmountFrom('5.05')` is `'4.95'`: `floor(delivered / 1.02)` to 2 places on integers.
+  - `followOnRefusal`: cash-out on `near` names Weave's NEAR deposits being unavailable; on `monad` says cash-outs don't run there; `supply` with no venue offering it names the chain; `send` with a venue offering it answers undefined; every refusal ends "Nothing was signed or sent."
+  - `strandedReply('USDC','5')` includes "you are holding" and "nothing was paid out"; with undefined it includes no number.
+  - `assertNativeReserve`: wallet holds 0.01477 SOL and asks 0.01477 refuses "Keep about 0.005 SOL for network fees. You can spend up to 0.00977 SOL here. Nothing was signed or sent."; asks 0.009 passes; a token other than native passes with no read; a failed balance read passes, because it must not block a trade.
+- [ ] **Step 2: Run** `pnpm exec vitest run chain-sequence`. Expected: FAIL.
+- [ ] **Step 3: Implement.** Call `assertNativeReserve` in both `prepareChainAction` and `chainRaceFacts`, so a doomed amount is refused before the agents run. Chat wiring is Task 5.
+- [ ] **Step 4: Run** the test file, the `parse-cashout` tests, `import-purity`, `routes-load-with-two-networks`, `tsc`, then eslint. Expected: PASS.
+- [ ] **Step 5: Commit** `feat(dapp): read a swap and what comes after it`.
+
+### Task 5: Swap then cash out
+
+**Files:**
+
+- Create: `apps/dapp/hooks/use-chain-sequence.ts`, `apps/dapp/lib/chains/sequence-flow.ts`, `apps/dapp/components/intents/chain-sequence-steps.tsx`, `apps/dapp/lib/__tests__/chain-sequence-flow.test.ts`
+- Modify: `apps/dapp/components/intents/intent-chat.tsx`, `apps/dapp/components/intents/cashout-currency-question.tsx`
+
+**Interfaces:**
+
+- Consumes: Task 4's types, Task 2's route, `useChainAction`, `useCashout.open`.
+- Produces in `lib/chains/sequence-flow.ts`:
+
+```ts
+export type SequenceStage = 'swap' | 'measuring' | 'ready' | 'next' | 'stranded' | 'done'
+export function stageAfterSwap(phase: ChainActionPhase): SequenceStage | undefined
+export function stageAfterMeasure(
+  delivered: string | undefined,
+  attempts: number,
+  maxAttempts: number
+): SequenceStage | 'keep'
+export const MEASURE_INTERVAL_MS = 3_000
+export const MEASURE_ATTEMPTS = 20
+```
+
+- Produces in the hook: `useChainSequence(chainAction, cashout)` returning `{ sequence, stage, delivered, error, start(request, text), runNext(), clear() }`.
+
+- [ ] **Step 1: Write failing tests:**
+  - `stageAfterSwap('settled')` is `'measuring'`.
+  - `pending` and `failed` are `'stranded'`, and the signing, submitting, review and building phases are undefined. `pending` never reaches `'ready'` on any path.
+  - `stageAfterMeasure('5', 1, 20)` is `'ready'`. Undefined before the limit is `'keep'`, and at the limit is `'stranded'`.
+- [ ] **Step 2: Run** `pnpm exec vitest run chain-sequence-flow`. Expected: FAIL.
+- [ ] **Step 3: Implement the hook.**
+  - `start` reads the output token's balance from the balances route when step 1's card reaches `review`, and if that read fails, marks `before` as unknown.
+  - On `settled`, it polls until the amount rises. An unknown `before` goes straight to stranded rather than guessing.
+  - `runNext` for cash-out calls `cashout.open({ amount: cashoutAmountFrom(delivered), currency })`. It starts only from a press.
+  - It compares the connected account with the one step 1 was signed by, using `accountMismatch`, and refuses with that sentence if they differ.
+  - It adds no second latch: a new race is still what lifts `chainAction`'s latch.
+- [ ] **Step 4: Wire the chat.**
+  - In `startCashout`, `kind: 'sequence'` first checks `followOnRefusal`, then asks the currency with the existing question if none is named, then runs the race for `{ kind: 'swap', amount, tokenIn: token, tokenOut: 'USDC' }`.
+  - `handleSubmit` tries `parseChainSequence` before `parseChainAction`.
+  - `ChainSequenceSteps` shows "1 Swap 0.5 SOL to USDC" and "2 Cash out to {currency}" before anything is signed, the step in progress, and a "Cash out {amount} USDC" button at `ready`.
+  - At `stranded`, it shows `strandedReply`. A pending step 1 shows the existing pending card, unchanged.
+- [ ] **Step 5: Run** the test file, `agents-chain-race`, `import-purity`, `routes-load-with-two-networks`, `tsc`, then eslint. Expected: PASS.
+- [ ] **Step 6: Commit** `feat(dapp): swap then cash out on solana, sui and avalanche`.
+
+### Task 6: Swap then deposit, stake or send, and plain send
+
+**Files:**
+
+- Create: `apps/dapp/lib/chains/send.ts`, `apps/dapp/lib/__tests__/chain-send.test.ts`
+- Modify: `apps/dapp/lib/chains/types.ts`, `apps/dapp/lib/chains/parse-action.ts`, each chain's `module.ts`, `apps/dapp/hooks/use-chain-sequence.ts`, `apps/dapp/components/intents/chain-sequence-steps.tsx`, `apps/dapp/lib/agents/chain-routes.ts`
+
+**Interfaces:**
+
+- Consumes: the deposit builders in `lib/weave/deposit/*` and `lib/chains/evm/deposit.ts`, which already build and check one exact transfer. Reuse them; do not write a second transfer check.
+- Produces: `ChainActionKind` gains `'send'`. `ChainActionRequest` gains `recipient?: string`. `createSendVenue(chain: ChainWithActions): ChainVenue` with id `send`, name `Wallet transfer`, kinds `['send']`, and no `quote`, so it never enters a race.
+
+- [ ] **Step 1: Write failing tests:**
+  - `parseChainAction('send 5 USDC to {address}')` gives kind `send` with the recipient unchanged in case.
+  - On each chain, `prepare` builds exactly one transfer of that token and amount to that recipient, and `assertSafe` refuses another recipient, another amount, another token and trailing data.
+  - A recipient that isn't valid on this chain is refused, including an EVM address on Solana and a Solana address on Sui.
+  - A token contract as recipient is refused.
+  - A NEAR recipient not registered with the token is refused with a plain sentence, since the transfer would fail.
+  - Native SOL, SUI or NEAR that the builder can't move is refused plainly.
+  - `assertWithinCap` applies.
+  - A send never enters `quoteChainRoutes`, and a typed send goes straight to a review card with no race.
+  - In the sequence: follow-on `supply`, `stake` or `send` prepares with `amount` equal to the measured delivery, and `tokenIn` equal to the swap's output.
+- [ ] **Step 2: Run** `pnpm exec vitest run chain-send`. Expected: FAIL.
+- [ ] **Step 3: Implement.** The review card shows the full recipient and the note "Transfers can't be undone. Check the address." Step 2's press calls `chainAction.release()` and then `prepare`, only from `stage === 'ready'`, so the latch is lifted once and only after step 1 is proven settled. Measured amounts over the token's decimals are floored.
+- [ ] **Step 4: Run** the test file, `chain-sequence`, `import-purity`, `routes-load-with-two-networks`, `tsc`, then eslint. Expected: PASS.
+- [ ] **Step 5: Commit** `feat(dapp): swap then deposit, stake or send on every chain`.
+
+### Task 7: The chat understands all of it in ordinary words
+
+**Files:**
+
+- Modify: `apps/dapp/lib/orchestrate/capabilities.ts`, `apps/dapp/lib/chains/capabilities.ts`, `apps/dapp/components/intents/intent-chat.tsx`, `apps/dapp/lib/chains/parse-sequence.ts`
+- Test: `apps/dapp/lib/__tests__/orchestrate-capabilities-chain.test.ts`, `apps/dapp/lib/__tests__/chain-sequence.test.ts`
+
+**Interfaces:**
+
+- Produces: `sequenceFromReading(reading: UnderstoodIntent): ChainSequenceRequest | null` in `lib/chains/parse-sequence.ts`.
+
+- [ ] **Step 1: Write failing tests.**
+  - A reading with a swap and an off-ramp, lend or send `followOn` converts to the matching sequence. One that has no `followOn` returns null.
+  - `capabilitySheet` on Solana, Sui and Avalanche says swap then cash out runs. On NEAR it says swap then deposit and send run, and cash-out doesn't. On Monad it says swap and send run, and cash-out and deposit don't.
+  - Limit orders remain listed as not available off Stellar.
+  - `chainHelp` lists what works in the new forms.
+- [ ] **Step 2: Run** those files. Expected: FAIL.
+- [ ] **Step 3: Implement.** Off Stellar, where the orchestrator's reading has a `followOn`, the chat runs `sequenceFromReading` through the same path as Task 5, and never reaches the Stellar branches of `startIntent`. Drop `followOn` silently nowhere: a follow-on that can't convert is refused with `followOnRefusal`.
+- [ ] **Step 4: Verify the whole change.** From `apps/dapp` run `pnpm exec tsc --noEmit`, `pnpm exec next lint --quiet` and `pnpm exec vitest run --maxWorkers=4 --minWorkers=1`. Expected: exit 0 for the first two. The only failures allowed are live-network tests in code this plan doesn't touch, each named in the report with its cause.
+- [ ] **Step 5: Commit** `feat(dapp): read multi-step requests in ordinary words on every chain`.
+
+## Not in this plan
+
+- Limit orders off Stellar (Kamino, DeepBook, Rhea, CoW) and new apps get their own plans. Research is in the session's scratchpad.
+- Cash-out from NEAR or Monad: NEAR needs Weave to fix `Incorrect depositMode`. Monad needs Weave support, or a bridge step that needs gas on another chain.
+- Trading a token that isn't in the chain's token table. Balances show it and mark it unlisted; a swap of it is refused as today.
+- More than one follow-on after a swap. Stellar also runs one.
+- Fixing 1Click's Monad errors, which are upstream.
+- A history screen for chain races.
+- A real signed transaction: the person does that with a funded wallet.

+# Agents That Talk To Each Other Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Agents read each other's strategies, question each other and decide their own final plan, live in the chat, on all six chains, within about 20 seconds.
+
+**Architecture:** First takes run as today. A new engine, `lib/agents/talk.ts`, then runs ask, answer and final turns under one shared deadline, inside the existing compete request. Final plans go through the existing validate, settle and measure path, and scoring runs on them. New SSE frames carry first takes and talk lines, and the panel renders them with existing components.
+
+**Tech Stack:** Next 15 route handler, SSE, React 19, framer-motion, vitest (no DOM), OpenAI-compatible chat completions, Anthropic SDK.
+
+**Spec:** `docs/superpowers/specs/2026-11-05-agents-talking-design.md`
+
+## Global Constraints
+
+- Work only in `.claude/worktrees/agents-talk`, branch `feat/agents-talk`, stacked on `feat/chain-sequences`. Never switch branches in the main checkout. Never run `pnpm install` in the worktree.
+- `SYSTEM_PROMPT`, `CHAIN_BRIEF`, `SUBMIT_PROPOSAL_TOOL` and `propose` don't change. Stellar's prompt stays pinned by hash.
+- No restyling. Use `agentBubble`, `systemPill`, `AgentAvatar`, `ThinkingDots`, and the existing card, tokens and layout.
+- Deadlines from the clock start at `competition:started`: talk opens by 8000ms, or when the second first take lands, never after 14000ms. Everything closes at 20000ms. Messages are at most 2 sentences and 160 characters. Reveal gap is 700ms, shrinking to 150ms when behind.
+- A model writes every agent word. No scripted lines, and no prompt words steering toward or away from agreement.
+- Nothing is signed or sent by this work. Every final plan passes validate, settle and measure. Only the person's words set amount and tokens.
+- No new dependencies. Vitest has no DOM and no BigInt literals, so logic goes in pure helpers under `lib/`.
+- Commit subjects are lowercase, with the header at most 100 characters. No co-author or attribution lines. Stage files by name, never `.claude/` or `.next-verify/`. No push or deploy unless the owner asks.
+- Run tests from `apps/dapp`: `npx vitest run <files> --reporter=basic --maxWorkers=3 --minWorkers=1`, always including `lib/__tests__/import-purity.test.ts` and `lib/__tests__/routes-load.test.ts`, and excluding `**/*.live.test.ts`.
+
+## Review Focus
+
+1. Every agent holds off on a chain and on Stellar: no signable card, no "agents were unavailable" text, no winner frame. Test in Task 5.
+2. A held agent reached through the winner's-route fallback, live or reopened. Test `canReview` in Task 6.
+3. A person's note arrives mid-talk: the hook cancels and its queued reveals never fire. Test the pure queue in Task 2; check by hand in Task 7.
+4. A planted instruction in another agent's message or a route note. Test in Task 3 and run in Task 7.
+5. An agent names itself, a failed agent or an unknown name as its target. Test in Task 3.
+
+---
+
+### Task 1: Measure speed, go or no-go
+
+**Files:**
+
+- Create: `apps/dapp/lib/agents/evals/talk-speed.ts`
+- Modify: `apps/dapp/package.json` (script `agents:talk-speed`)
+
+**Interfaces:**
+
+- Produces: the provider settings used in Task 4, recorded in `apps/dapp/lib/agents/evals/RESULTS.md`.
+
+- [ ] **Step 1: Write the script.** For each default-roster model, send a talk-shaped prompt of about 500 tokens with one small tool, and record milliseconds and whether a tool call came back. Try normal settings and reasoning-off settings. Reasoning-off bodies to try: DeepSeek `thinking: { type: 'disabled' }`, Groq `reasoning_effort: 'none'`, OpenRouter `reasoning: { enabled: false }`. Also record first takes through `createBrain().propose`. Calls: ten for DeepSeek and Groq, five for each OpenRouter model, two first takes per OpenRouter model. Print a table with median, p90 and answered count. No Anthropic key exists locally, so report it as not measured.
+- [ ] **Step 2: Run it** from `apps/dapp`: `npx tsx --env-file=<main checkout>/apps/dapp/.env.local lib/agents/evals/talk-speed.ts`
+- [ ] **Step 3: Decide.** Go when every line-up `lineUp` can seat has at least two models with a talk p90 under 3000ms. **No-go: stop and bring the numbers to the owner.**
+- [ ] **Step 4: Record the table in `RESULTS.md` and commit**: `docs(dapp): measure how fast agents can talk`
+
+### Task 2: Talk lines, wording and reveal pacing
+
+**Files:**
+
+- Create: `apps/dapp/lib/agents/talk-lines.ts`, `apps/dapp/lib/__tests__/agents-talk-lines.test.ts`
+- Modify: `apps/dapp/lib/agents/pacing.ts`
+
+**Interfaces:**
+
+- Produces, in `talk-lines.ts`, with no server imports:
+  - `type TalkLine = { kind: 'turn'; turn: 'ask' | 'answer' | 'final'; agents: string[] } | { kind: 'reading'; agent: string; of: string[] } | { kind: 'asked'; agent: string; to: string; text: string } | { kind: 'answered'; agent: string; to: string[]; text: string } | { kind: 'no_answer'; agent: string; to: string[] } | { kind: 'changed'; agent: string } | { kind: 'held'; agent: string }`
+  - `type ThreadItem = { type: 'take'; agent: string } | { type: 'line'; line: TalkLine }`
+  - `talkPill(line, nameOf: (key: string) => string): string | undefined`, for `reading`, `no_answer`, `changed` and `held`
+  - `talkSpeaker(line, nameOf): string | undefined`, for `asked` and `answered`, like `Sonnet to Jeff`
+  - `waitingAgents(agents: string[], items: ThreadItem[], answeredOrFailed: (key: string) => boolean): string[]`
+  - `showTakes(items: ThreadItem[], phase): boolean`
+  - `ALL_HELD_LINE`, `allHeld(views): boolean`
+- Produces, in `pacing.ts`: `planTalkReveal(lastRevealMs: number, elapsedMs: number, closeMs?: number): number`, returning when an item shows, in ms from race start.
+
+- [ ] **Step 1: Write the failing tests.**
+  - `talkPill` on `reading` of one, two and three agents gives `Sonnet is reading Jeff's strategy`, `Sonnet is reading Jeff's and Opus's strategies`, and `Sonnet is reading Jeff's, Opus's and Ling's strategies`.
+  - `talkPill` gives `Jeff did not answer in time.`, `Sonnet changed its strategy.`, `Opus would not do this now.`, and undefined for `asked`, `answered` and `turn`.
+  - `talkSpeaker` gives `Sonnet to Jeff`, and `Jeff to Sonnet and Opus`.
+  - `waitingAgents` lists agents with no take and no failure before any turn. During a turn it lists that turn's agents who haven't spoken yet. An agent's own `asked` or `answered` removes it from that turn. A later turn replaces the earlier one.
+  - `showTakes` is true while competing, and after decided only if a `line` other than `turn` exists.
+  - `allHeld` is true only if at least one view is held and every answered view is held.
+  - `planTalkReveal(0, 0)` is 700. `planTalkReveal(1000, 900)` is 1700. `planTalkReveal(1000, 5000)` is 5000. With the last reveal at 19900 and elapsed 19000, the gap is 150, giving 20050. It never returns earlier than elapsed.
+- [ ] **Step 2: Run them and see them fail.**
+- [ ] **Step 3: Implement.**
+- [ ] **Step 4: Run them and see them pass, then commit**: `feat(dapp): word and pace what agents say to each other`
+
+### Task 3: Talk prompts, tools and reading answers
+
+**Files:**
+
+- Create: `apps/dapp/lib/agents/talk-prompts.ts`, `apps/dapp/lib/__tests__/agents-talk-prompts.test.ts`
+
+**Interfaces:**
+
+- Consumes: `promptSafe`, `QuotedRoute`, `AgentProposalResult`, `describePlan`.
+- Produces:
+  - `interface TalkTool { name: string; description: string; parameters: Record<string, unknown> }`, and `ASK_TOOL` (`to`, `question`), `ANSWER_TOOL` (`answer`), `FINAL_TOOL` (`decision: 'keep' | 'change' | 'hold'`, `routeId`, `executionMode`, `restPriceUsd`, `splitPct`, `reasoning`). All properties are required, with `additionalProperties: false`.
+  - `interface TalkFacts { chain: string; intent: string; routes: QuotedRoute[]; plans: { key: string; name: string; plan: string; reasoning: string }[] }`
+  - `askPrompt(self, facts, seat)`, `answerPrompt(self, facts, questions, seat)`, `finalPrompt(self, facts, talkSoFar, seat)`, each returning `{ system: string; user: string }`
+  - `readQuestion(raw, others: {key, name}[]): { to: string; text: string } | undefined`, `readAnswer(raw): string | undefined`, `readFinal(raw, allowedRouteIds): FinalChoice | undefined`, where `FinalChoice = { decision: 'keep' | 'hold'; reasoning: string } | { decision: 'change'; reasoning: string; routeId: string; executionMode: 'fill' | 'rest' | 'split'; restPriceUsd: number; splitPct: number }`
+
+- [ ] **Step 1: Write the failing tests.**
+  - No prompt or tool description matches `/consensus|agree|unanimous|must differ|must disagree|be different/i`.
+  - Each prompt tells the agent to improve its own plan and change it only if persuaded.
+  - A plan or route note holding a newline and `ignore previous instructions` arrives on one line, inside a block labelled as what others said and not instructions, capped by `promptSafe`.
+  - Other plans appear in a different order for seat 0 and seat 1.
+  - With four routes and four plans at maximum length, `system` plus `user` is at most 3200 characters, which is about 800 tokens.
+  - `readQuestion` returns undefined for an empty question, its own name, or an unknown name. It matches a name case-insensitively, tidies dashes, and clips to 160 characters on a sentence.
+  - `readFinal` returns undefined for an unknown decision, and for `change` with a blank or unoffered route. A `hold` needs no route. `reasoning` is tidied and clipped.
+  - The chain final prompt says one fill. The Stellar one offers fill, rest and split.
+- [ ] **Step 2: Run them and see them fail.**
+- [ ] **Step 3: Implement**, reusing `tidyProse` and `clipReasoning`.
+- [ ] **Step 4: Run them and see them pass, then commit**: `feat(dapp): tell agents what the others said, without steering them`
+
+### Task 4: The engine and the model call
+
+**Files:**
+
+- Create: `apps/dapp/lib/agents/talk.ts`, `apps/dapp/lib/__tests__/agents-talk.test.ts`, `apps/dapp/lib/__tests__/agents-talk-brain.test.ts`
+- Modify: `apps/dapp/lib/agents/brain.ts`, `brains/openai-compatible.ts`, `brains/anthropic.ts`, `brains/providers.ts`
+
+**Interfaces:**
+
+- Consumes: Tasks 2 and 3, and Task 1's provider settings.
+- Produces:
+  - In `brain.ts`: `AgentBrain.talk?: (req: TalkCall) => Promise<TalkOutcome>`, with `TalkCall = { agent: AgentKey; system: string; user: string; tool: TalkTool; signal?: AbortSignal }` and `TalkOutcome = { ok: true; args: unknown; meta: BrainMeta } | { ok: false; error: BrainErrorCode; meta: BrainMeta; retryAfterMs?: number }`. Optional, so fake brains stay valid.
+  - In `brain.ts`: `AgentProposalResult.held?: true`.
+  - In `providers.ts`: `ProviderConfig.talk?: { body?: Record<string, unknown>; maxTokens?: number }`.
+  - In `talk.ts`: `TALK_OPEN_MS = 8000`, `TALK_LATEST_OPEN_MS = 14000`, `TALK_CLOSE_MS = 20000`, and:
+
+```ts
+runTalk(input: {
+  seats: { key: string; name: string; talk: NonNullable<AgentBrain['talk']> }[]
+  takes: Promise<AgentProposalResult | undefined>[] // same order as seats
+  facts: Omit<TalkFacts, 'plans'>
+  startedAt: number
+  emit: (line: TalkLine) => void
+  applyFinal: (agent: string, choice: FinalChoice) => AgentProposalResult | undefined
+  closeLateTakes: () => void // aborts first takes still running, called at close if anyone answered
+  onRateLimited: (agent: string, retryAfterMs: number | undefined) => void
+}): Promise<{ finals: AgentProposalResult[]; talked: boolean; questions: number; changed: number; held: number }>
+```
+
+- [ ] **Step 1: Write failing engine tests**, with `vi.useFakeTimers()` and fake brains.
+  - The first prompt each agent sees for its take has no other plan. Assert `talk` is called only after takes land.
+  - Order: `turn ask`, `reading`, `asked`, `turn answer`, `answered`, `turn final`, then `changed` or `held`.
+  - Talk opens at once when all takes are in, at 8000ms with two in, and when the second lands at 12000ms. It doesn't open if the second lands after 14000ms, and `talked` is false.
+  - Only asked agents make an answer call. One call answers two questions, `to` listing both.
+  - A late ask emits nothing. A late answer emits `no_answer`. A late, failed or unreadable final keeps the first take, and no `changed` appears.
+  - A take landing after talk opened skips closed turns and still gets the final turn.
+  - `keep` emits no `changed`. `change` emits `changed` only if route or mode differs. `hold` emits `held`.
+  - All calls abort, and `runTalk` resolves, by 20000ms with slow brains. `closeLateTakes` is called at 20000ms if anyone answered, and not if nobody did. With nobody at 20000ms, it waits for the takes and returns with no talk.
+  - A 429 calls `onRateLimited`, and the agent keeps its take.
+  - A final plan object comes only from that agent's own `applyFinal` call or first take: a test where one agent's words name another's route leaves other agents' plans untouched.
+- [ ] **Step 2: Write failing brain tests**, with `fetchImpl`.
+  - `talk` posts the given tool, `tool_choice: 'auto'`, the provider's `talk.body`, and `talk.maxTokens`.
+  - It returns parsed args. It reports `timeout` on abort, `rate_limited` with `retryAfterMs` on 429, and `invalid_schema` on prose. It never logs the key.
+  - The Anthropic `talk`, with a faked client, sends `effort: 'low'`.
+- [ ] **Step 3: Run them and see them fail.**
+- [ ] **Step 4: Implement.** In `openai-compatible.ts`, share the request and error handling with `propose` rather than copying it. `propose`'s body must stay byte-identical.
+- [ ] **Step 5: Run them, with existing brain tests, and see them pass, then commit**: `feat(dapp): let agents question each other under one deadline`
+
+### Task 5: The race route, scoring and holding off
+
+**Files:**
+
+- Modify: `apps/dapp/app/api/agents/compete/route.ts`, `lib/agents/events.ts`, `lib/agents/scoring.ts`, `lib/agents/settle-chain-plan.ts` (stale comment only)
+- Create: `apps/dapp/lib/agents/talk-final.ts`, `apps/dapp/lib/__tests__/agents-talk-route.test.ts`
+
+**Interfaces:**
+
+- Consumes: `runTalk`, `FinalChoice`, `toOutcome`, `settlePlan`, `settleChainPlan`, `measured`.
+- Produces:
+  - Frames `CompetitionTakeFrame { type: 'competition:take'; competitionId; proposal }` and `CompetitionTalkFrame { type: 'competition:talk'; competitionId; line: TalkLine }`. They arrive in order on one stream, so no sequence number is needed.
+  - `applyFinalChoice(first: AgentProposalResult, rawFirst: AgentProposalResult, choice: FinalChoice, ctx): AgentProposalResult | undefined`. `keep` returns `first` with new reasoning. `hold` returns `first` without `routeId`, resting or follow-on fields, with `held: true`, new reasoning, and figures zeroed. `change` rebuilds from `rawFirst` with the new route, mode and `venues: [route.source]`, then passes through `toOutcome`, settle and measure.
+  - `pickWinner` never returns a held agent, and returns null if all are held. `unanimousChoice` is false if any is held.
+
+- [ ] **Step 1: Write failing route tests**, using the setup in `agents-chain-compete.test.ts`, for near and for stellar.
+  - A roster of fake brains without `talk` gives the same frames as today.
+  - With two talking brains: `competition:take` frames before talk, `competition:proposal` only for final plans and only after talk, and scoring on finals.
+  - A `change` to an unoffered route keeps the first take. A `change` to an offered route sends that route and measured figures.
+  - All hold: `competition:proposal` frames with `held: true`, no route, no winner frame, the race recorded with a null winner, and no error frame.
+  - Some hold: the winner is a non-held agent and `unanimous` is false.
+  - `competition:take` carries no route.
+- [ ] **Step 2: Run them and see them fail.**
+- [ ] **Step 3: Implement.** Talk runs when at least two rostered brains have `talk`, otherwise the path stays as today. Keep each agent's `AbortController` so `closeLateTakes` can abort it. Analytics: look at `RaceInput`. If counts fit without a schema change, add `questions`, `changed` and `held`. Otherwise leave them out and say so in the report. Correct the stale comment in `settle-chain-plan.ts`.
+- [ ] **Step 4: Run them with `agents-chain-compete`, `compete-route-log`, `agents-chain-race`, `registry` and the Stellar prompt-hash test, and see them pass, then commit**: `feat(dapp): race on final plans after the agents have talked`
+
+### Task 6: Hook, panel, saving
+
+**Files:**
+
+- Modify: `apps/dapp/hooks/use-competition.ts`, `components/intents/competition-panel.tsx`, `components/intents/intent-chat.tsx`, `lib/agents/competition.ts`, `lib/agents/chain-race.ts`, `lib/chat-history.ts`
+- Create: `apps/dapp/lib/__tests__/agents-talk-review.test.ts`
+
+**Interfaces:**
+
+- Consumes: Task 2 helpers, and Task 5 frames.
+- Produces:
+  - `CompetitionState.thread?: ThreadItem[]`, `CompetitionState.takes?: Record<string, AgentProposalView>`, `AgentProposalView.held?: true`, `ChatTurn.talk?: { thread: ThreadItem[]; takes: Record<string, AgentProposalView> }`.
+  - `canReview(view: AgentProposalView | undefined, route: unknown, restored: boolean): boolean`, in `chain-race.ts`.
+
+- [ ] **Step 1: Write failing tests.**
+  - `canReview` is false for a held view, live or restored. It is false restored with no route, and true live with no route on a non-held view, as today.
+  - `syncTurns` keeps a local `talk` when the server's copy has none. `saveTurnRemote`'s body has no `talk`.
+  - Reveal: a queue built from `planTalkReveal` keeps frame order and final cards land after the last talk item.
+- [ ] **Step 2: Run them and see them fail.**
+- [ ] **Step 3: Implement the hook.** Takes and lines go through one queue using `schedule`, so cancelling clears them. In a talk race, final cards reveal after the queue, 400ms apart. The winner waits for them through `planDecision`.
+- [ ] **Step 4: Implement the panel.** Render the thread above the final cards as the spec's table says. No Review on a take. Dots from `waitingAgents`. The Broadcasting pill shows only when nothing is in the thread. Held cards show their reasoning and tag `Would not do this now`, without figures or Review. Show `ALL_HELD_LINE` when `allHeld`. Exclude held from the `All N agents agree` count. No new class names beyond what's already there.
+- [ ] **Step 5: Wire `intent-chat.tsx`.** Guard `handleExecute` with `canReview`. Pass the thread from a restored turn. Save `talk` with the turn.
+- [ ] **Step 6: Run tests and `npx tsc --noEmit`, then commit**: `feat(dapp): show agents talking in the chat`
+
+### Task 7: Eval and whole-branch verification
+
+**Files:**
+
+- Create: `apps/dapp/lib/agents/evals/talk-eval.ts`
+- Modify: `apps/dapp/package.json` (script `agents:eval:talk`), `apps/dapp/lib/agents/evals/RESULTS.md`, `apps/dapp/.env.example` only if a setting was added
+
+**Interfaces:**
+
+- Consumes: `runTalk`, golden set, `createBrain`.
+
+- [ ] **Step 1: Write the eval.** For golden cases, run first takes and talk across given models. Report how often all first takes chose the same plan, how often all final plans did, how many plans changed, and how many held. No target is set. Add a case where a planted instruction arrives in another agent's plan, and report whether any model obeyed.
+- [ ] **Step 2: Run it** on three cases plus the injection case with DeepSeek and Groq only, to protect the OpenRouter limit. Record the results in `RESULTS.md`.
+- [ ] **Step 3: Run format, lint, typecheck and all non-live tests.** Compare any failures against the base branch and say which ones are new.
+- [ ] **Step 4: Run the app locally** and trigger a real race, at least on NEAR and Stellar. Time it, and capture what the talk reads like. Nothing gets signed.
+- [ ] **Step 5: Run a fresh whole-branch review**, fix findings, and commit: `docs(dapp): record how talk changes what agents decide`
+- [ ] **Step 6: Report** to the owner: what ran, what didn't, and what needs them (credits, a preview with its own Postgres, a real wallet).

+# Limit Orders Off Stellar Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** A person can place, watch, cancel and collect a limit order on Solana, Sui, NEAR and Avalanche, Monad refuses in words, and race agents can recommend resting an order instead of filling now.
+
+**Architecture:** A limit order is a new `ChainActionKind`, `limit`, that goes through the existing prepare, assert, sign and submit path, one venue per chain. Orders live on the chain or in CoW's book and are read back, so there is no database. A `LimitBook` on the chain module reads orders and builds their exits (cancel, collect). The race gets a resting option beside its fill routes, and a rest proposal becomes a `limit` request when pressed.
+
+**Tech Stack:** Next 15, `@solana/kit` 8, `@mysten/sui` 2.31.2, viem 2, wagmi 2, vitest.
+
+**Spec:** the user's request, "build limit orders" after "the AI should be able to do bundled swaps, limit swaps and so on on all chain", and the venue research in `docs/research/2026-11-05-limit-orders/` (`solana.md`, `sui.md`, `near.md`, `evm.md`). Those reports hold the addresses, discriminators, account orders and move targets. Read the one for your task. Facts marked unverified there are not facts.
+
+## Global Constraints
+
+- **No new dependencies.** `pnpm install` is not available in this worktree, `limo-sdk` pins kit 8.3.0 and pulls in web3.js v1, and `deepbook-v3` needs a newer `@mysten/sui`. Build instructions by hand with what is installed. A package may be read from a tarball in the scratchpad (`npm pack`), never added.
+- Work only in `.claude/worktrees/limit-orders`, branch `feat/chain-limit-orders`. Never run `pnpm install` here: `node_modules` are junctions into the main checkout. Never switch branches in the main checkout.
+- Nothing is ever signed or sent. Live checks read and simulate only, in files named `*.live.test.ts`. Run a live test only by its exact file name. Every other test run excludes them with `--exclude '**/*.live.test.ts'`.
+- Every focused run also includes `lib/__tests__/import-purity.test.ts` and `lib/__tests__/routes-load.test.ts`. Run from `apps/dapp` with `npx vitest run <files> --reporter=basic --maxWorkers=3 --minWorkers=1`.
+- Stellar does not change. Its prompt stays pinned by hash, and `chainCapabilities('stellar')` stays undefined.
+- Only the person's own words decide the amount, the tokens and a stated price. A race may propose a resting price only inside the band in Task 9, and the person presses Review and signs.
+- A refusal says what happened and ends `Nothing was signed or sent.`
+- Limit orders never cross the market on purpose: an order that would fill at once at a worse price than the market is refused, by `assertRestingPrice`.
+- Every venue ships its real logo in the task that adds it. A test enforces this.
+- Vitest has no DOM and no BigInt literals (`BigInt('10')`). Push logic into pure helpers under `lib/`.
+- Commit subjects are lowercase and at most 100 characters, with body lines at most 100. No co-author lines or attribution. Stage files by name, never `.claude/` or `.next-verify/`.
+- Don't touch `naira-payout-card.tsx`, `bank-picker.tsx` or `use-naira-payout.ts`.
+
+## Review Focus
+
+1. A typo in the price: "sell 1 SOL at 1.10" must be refused in words, not rest forever or fill at a loss. Pinned in Task 1.
+2. The direction of a price: "swap 50 USDC to SOL at 90" spends 50 USDC for at least 0.5556 SOL, and rounding never gives less than the stated price. Pinned in Task 1.
+3. An order that filled while its card was open: pressing Cancel on it must collect or say so, never fail silently or sign something useless. Pinned in Task 7.
+4. Someone else's order: an exit for an order id the connected account doesn't own is refused on the server. Pinned in Tasks 2, 3, 4, 5, 6.
+5. Too little native coin: an order that leaves too little to pay its cost and fees is refused before signing, and the cost is shown first. Pinned in Task 2.

+
+### Task 1: The maths and the words
+
+**Files:**
+
+- Create: `apps/dapp/lib/chains/limit.ts`, `apps/dapp/lib/chains/parse-limit.ts`
+- Modify: `apps/dapp/lib/chains/types.ts` (`ChainActionKind` adds `'limit'`; `ChainActionRequest` adds `limitPrice?: string | undefined`), `apps/dapp/lib/chains/parse-action.ts` (`racesFirst` false for `limit`)
+- Test: `apps/dapp/lib/__tests__/chain-limit.test.ts`
+
+**Interfaces:**
+
+- Produces, in `limit.ts`:
+  - `limitPair(tokenIn: string, tokenOut: string): { base: string; quote: string; selling: boolean } | undefined`. Quote is the stablecoin side (USDC or USDT), and nothing for two stablecoins or no stablecoin.
+  - `limitOutput(amountIn: string, price: string, selling: boolean, decimalsIn: number, decimalsOut: number): bigint`. Exact BigInt arithmetic. Selling: amount times price. Buying: amount divided by price. Always rounds up, so the order never accepts less than the stated price.
+  - `assertRestingPrice(price: string, marketUsd: number, selling: boolean, symbol: string): void`, which throws `ChainActionRefused`.
+  - `interface RestingOrder { id: string; venueId: string; tokenIn: string; tokenOut: string; amountIn: string; remainingIn: string; receivedOut: string; collectable?: { amount: string; symbol: string }[]; limitPrice?: string; status: 'open' | 'partly' | 'filled' | 'done'; expiresAt?: number; note?: string }`
+  - `interface LimitBook { openOrders(account: string, signal?: AbortSignal): Promise<RestingOrder[]>; prepareExit(account: string, orderId: string, action: 'cancel' | 'collect'): Promise<PreparedAction> }`
+- Produces, in `parse-limit.ts`:
+  - `parseChainLimit(text: string): ChainActionRequest | null`
+  - `limitSaid(request: ChainActionRequest, turns: readonly string[]): boolean`
+- Modifies: `ChainModule` adds `limitBook?: LimitBook`. `PreparedAction` adds `thenPrepareAgain?: true`, meaning this is a setup step and the same request must be prepared again once it settles.

Check the figure and send it again.

+- Create: `apps/dapp/app/api/chain/[chain]/orders/route.ts`
+- Modify: `apps/dapp/lib/chains/prepare.ts`, `apps/dapp/lib/chains/capabilities.ts` (and each chain's `capabilities.ts`), `apps/dapp/app/api/chain/[chain]/prepare/route.ts`
+- Test: `apps/dapp/lib/__tests__/chain-limit-routes.test.ts`
+
+**Interfaces:**
+
+- Consumes: Task 1.
+- Produces: `GET /api/chain/[chain]/orders?account=` returns `{ orders: RestingOrder[] }`, 404 `unknown_chain`, 400 `invalid_account`, 503 `orders_unavailable`, and rate family `read`. `POST` with `{ account, orderId, action }` returns a prepared action as the prepare route does, with rate family `build` and the same wallet gate as the prepare route. 422 with `error` for a refusal.
+- Produces: `assertLimitCanRun(chainApi: ChainModule, request: ChainActionRequest, account: string): Promise<void>` in `prepare.ts`, which `prepareChainAction` calls for `limit`.
+- Produces: `LIMIT_NOT_HERE: Partial<Record<ChainWithActions, string>>`, with `monad: "Monad has no limit order venue I would trust with your money yet. The only real option, Kuru, keeps deposits in an upgradeable contract with no audit I could find. Nothing was signed or sent."`
+
+- [ ] **Step 1: Write the failing tests**
+
+Cover, with a mocked module (as `chain-price-route.test.ts` does):
+
+- `prepareChainAction` for `limit` on `monad` throws the `LIMIT_NOT_HERE` copy.
+- A `limit` request with a price that fails `assertRestingPrice` is refused before the venue's `prepare` runs, and the venue was not called.
+- No live price: refused with `I have no live price for SOL, so I can't check that price. Nothing was signed or sent.`, venue not called.
+- A pair with no stablecoin: `Limit orders here need USDC or USDT on one side. Nothing was signed or sent.`
+- `assertNativeReserve` counts a venue's stated setup cost: a limit selling SOL with 0.0148 SOL held and a cost of 0.00684 SOL is refused, and the refusal names the cost.
+- GET and POST status codes above. POST with an `action` other than `cancel` or `collect` is 400. A module with no `limitBook` answers `{ orders: [] }` on GET and 422 on POST.
+
+- [ ] **Step 2: Run them to see them fail**
+- [ ] **Step 3: Implement.** `ChainVenue` gains `limitCost?: { amount: string; symbol: string }`, added to the native reserve for that venue. `assertAmountWithinCap` runs on a limit order as on any other action. Off Stellar help text (`chainHelp`) names limit orders where a venue exists.
+- [ ] **Step 4: Run them to see them pass, with import-purity and routes-load**

+- Modify: `apps/dapp/lib/chains/solana/venues.ts`, `module.ts`, `programs.ts`, `capabilities.ts`, `sign.ts` if needed
+
+**Interfaces:**
+
+- Consumes: Task 1 and 2. `decodeSolanaTransaction`, `associatedTokenAccount`, `ownWrappedSolAccount` from `assert-safe.ts`.
+- Produces: venue id `kamino-limit`, name `Kamino Limit Orders`, kinds `['limit']`, `limitCost` `0.00684 SOL`. `limoBook(): LimitBook`.
+- Pinned values: program `LiMoM9rMhrdYrfzUCxQppvxCSG1FcrUK9G8uLq4A1GF`, global config `prod7Mog8r56sn5dPwze8nVdf94veEawdxNNqd5v7A1`, instruction bytes and account order from `docs/research/2026-11-05-limit-orders/solana.md`. Pairs: SOL, USDC and USDT only.
+
+- [ ] **Step 1: Write the failing tests**
+
+- `buildCreate` for 1 SOL to USDC at 110 decodes to: `create_order` with input `1000000000`, output `110000000`, order type 0. Maker, ATAs and PDAs as the report says. An idempotent create of the output ATA is present, because the SDK omits it and fills can fail without it. Wrap, sync and close of wSOL are present.
+- USDC to SOL has no output ATA create, and no wrap.
+- `limoAssertSafe` passes that payload, and refuses each of: another global config, another maker, another vault, input or output amount changed by one, an extra system transfer to anyone, a close-account destination that isn't the maker, `update_order`, a second extra signer, and an order account the transaction doesn't create at exactly 424 bytes owned by the program.
+- `prepare` reads the live config (mocked) and refuses when `txn_fee_cost + ata_creation_cost` is above `10_000_000` lamports, or `new_orders_blocked` is set. The cost is inside the program's call, so the signed bytes can't show it.
+- `prepare` refuses a mint whose vault doesn't exist.
+- `decodeOrder` on a real order account, captured to a fixture by the live test, reads remaining, filled output, status and maker.
+- `prepareExit` refuses an order whose maker isn't the account, and a filled order offers `collect` (closes it for rent and tips) with the summary saying the SOL comes back.
+
+- [ ] **Step 2: Run them to see them fail**
+- [ ] **Step 3: Implement.** The order keypair is generated on the server with kit, signs the message, and is thrown away. Check that the wallet path keeps that signature: the transaction reaches the wallet partly signed, and `solanaAssertSafe` must accept exactly this one extra signer, which must be the account the transaction creates. `notes`: `This stays open until it fills or you cancel it. There is no expiry.`, `Costs about 0.003 SOL, probably not refunded, and locks 0.00384 SOL until you close the order.`, `Only Pyth Express Relay searchers fill it. It may never fill, and small orders are less likely to.`, `Kamino can upgrade this program, so your escrowed amount carries that risk.`
+- [ ] **Step 4: Run `solana-limo.live.test.ts` by its exact name.** It reads the config and one real order for the fixture, simulates a create for a public funded wallet, and asserts `getProgramAccounts` filtered by maker answers on `api.mainnet-beta.solana.com`. If that read is refused, `openOrders` answers from a list of order addresses the browser stored at signing, and the note in chat names `SOLANA_RPC_URL`.
+- [ ] **Step 5: Run all the task's tests, with import-purity and routes-load**

+- Modify: `apps/dapp/lib/chains/sui/safety.ts`, `policies.ts`, `venues.ts`, `module.ts`, `capabilities.ts`, `apps/dapp/lib/chains/venue-logos` (or wherever the logo table lives), `apps/dapp/public/`
+
+**Interfaces:**
+
+- Produces: `ReadObject = (argument) => string | undefined`, passed to `PtbPolicy.checkCall` as a fourth argument. Existing policies ignore it. Venue id `deepbook-limit`, name `DeepBook`, kinds `['limit']`. `deepbookBook(): LimitBook`.
+- Pinned values: package, pools and registry from `docs/research/2026-11-05-limit-orders/sui.md`. Pair: SUI/USDC only. Order type POST_ONLY, so it can never fill at once. Expiry now plus 7 days. Tick, lot and minimum read from the chain, never the indexer, which disagrees.
+
+- [ ] **Step 1: Settle the three unknowns by simulation.** In `sui-deepbook.live.test.ts`, simulate, without signing, for a public funded wallet:
+  1. `new`, `deposit`, `generate_proof_as_owner`, `place_limit_order`, then `public_share_object`, all in one transaction.
+  2. `pay_with_deep = false` on POST_ONLY.
+  3. `balance_manager::register_balance_manager`, reading its Move source first. Allow it only if it does nothing but record the owner's id in the registry.
+
+  Record the outcomes at the top of `deepbook.ts`. If (1) fails, first use is two signatures: creating the manager returns `thenPrepareAgain`. If (2) fails, the order needs DEEP: `prepare` reads `get_order_deep_required`, and if the manager and wallet can't cover it, refuses with `DeepBook needs about ${n} DEEP in your wallet to place this. Nothing was signed or sent.` If (3) isn't safe, the browser stores the manager id per wallet, and a new device shows a new manager.
+
+- [ ] **Step 2: Write the failing tests**
+
+- Selling 2 SUI at 1.10 builds: deposit 2 SUI, place with `is_bid` false, price and quantity on tick and lot, POST_ONLY, expiry 7 days on, then share only if the manager is new.
+- Buying with 11 USDC at 1.00 deposits 11 USDC and places a bid for 11 SUI.
+- Below 1 SUI: `DeepBook's smallest SUI order is 1 SUI. Nothing was signed or sent.` A quantity off the lot rounds down, and the card shows the rounded figure.
+- `DEEPBOOK_POLICY` passes those, and refuses each of: `mint_trade_cap`, `mint_deposit_cap`, `mint_withdraw_cap`, `new_with_custom_owner`, `set_owner`, another pool id with the right types, wrong type arguments, price or quantity changed, order type other than POST_ONLY, expiry past 8 days, `public_share_object` of anything but a `BalanceManager`, and a deposit coin that differs from the expected amount.
+- An existing manager whose on-chain owner isn't the account is refused before building.
+- `prepareExit` cancel builds `cancel_order` then `withdraw_all` for both coins in one transaction, with `TransferObjects` to the account only. `collect` builds `withdraw_all` for both. An order or manager that isn't the account's is refused.
+- `openOrders` marks money waiting in the manager as `collectable`, and its summary never implies it is in the wallet.
+
+- [ ] **Step 3: Run them to see them fail**
+- [ ] **Step 4: Implement.** `notes`: `Filled or cancelled tokens stay in your DeepBook account until you press Collect, which needs a second signature.`, `Expires in 7 days.

+  })
+})
+```
+
+Also:
+
+- A sale at a point at or above the pool's `current_point`, or a purchase at or below it, is refused. `LimitOrderWithSwap` swaps a marketable part at once with no minimum out, so an order must never be marketable.
+- First use builds, in order: storage on `dclv2` as its own transaction, buy-token storage if unregistered, then the token transaction. `near_deposit` first when selling native NEAR.
+- `assertDclOrderSafe` passes that, and refuses: another contract, another pool, another `buy_token`, a changed amount or point, extra keys in `msg`, `client_id` other than `""`, deposit other than 1 yocto, gas above 250 TGas, storage above 0.5 NEAR. `ft_transfer_call` stays refused everywhere else: the existing `assertNearPayloadSafe` tests still pass unchanged.
+- `prepareExit` cancel is `cancel_order` with the remaining amount. `collect` is `cancel_order` with `amount: "0"`. Both no deposit, 180 TGas at most. An `order_id` whose `get_order` owner isn't the account is refused.
+- `openOrders` reads `list_active_orders` and marks `unclaimed_amount` as `collectable`.
+
+- [ ] **Step 2: Run them to see them fail**
+- [ ] **Step 3: Implement.** Proceeds of a NEAR purchase arrive as wNEAR, and a sale's proceeds as USDC. `notes`: `When it fills, press Collect to receive it. That needs a second signature.`, `First use sets aside up to 0.5 NEAR for storage on Rhea. I could not confirm it comes back.`, `A purchase pays out in wNEAR.`, `This stays open until it fills or you cancel it.`
+- [ ] **Step 4: Run `near-rhea-dcl.live.test.ts` by its exact name.** It reads the pool and a real order, checks the point formula against them, and reads `get_user_storage_detail`.

+
+**Interfaces:**
+
+- Produces: `SigningPayload` variant `{ family: 'evm-typed'; chainId: number; account: string; typedData: { domain: object; types: object; primaryType: 'Order'; message: CowOrder } }`, `SignedPayload` variant `{ family: 'evm-typed'; signature: string }`. Venue id `cow-limit`, name `CoW Protocol`, kinds `['limit']`, on Avalanche only. `cowBook(): LimitBook`.
+- Pinned values: settlement, relayer, WAVAX, USDC and the type fields from `docs/research/2026-11-05-limit-orders/evm.md`. `validTo` now plus 7 days, `feeAmount` `"0"`, both balances `erc20`, `partiallyFillable` true, kind `sell`, empty app data with no hooks, no partner fee.
+
+- [ ] **Step 1: Write the failing tests**
+
+- `prepare` walks by what the chain says: AVAX to sell and not enough WAVAX returns a `deposit()` on WAVAX with `thenPrepareAgain`. Too little allowance returns an exact `approve` to the relayer with `thenPrepareAgain`, never a max approval. Otherwise it returns the typed data.
+- `cowAssertSafe` passes those, and refuses each of: another `verifyingContract`, chain id or domain name, another receiver or the zero address, a changed token or amount, `validTo` past 8 days or in the past, `feeAmount` not `"0"`, a balance other than `erc20`, non-empty app data, and an `approve` with another spender or a higher amount.
+- `submit` recovers the signer with viem and refuses when it isn't the account, which also refuses smart-contract wallets in words. It posts the order, computes the UID locally, and refuses when the answer differs. It returns `{ ok: true, hash: uid, explorerUrl: 'https://explorer.cow.fi/avax/orders/' + uid }`.
+- A CoW answer of `SellAmountDoesNotCoverFee` reads `That is too small for CoW's solvers to fill. Try a few dollars more. Nothing was signed or sent.`
+- `signOn` refuses a typed payload for another chain or another account, and passes one to wagmi's `signTypedData`. The signing logic is a pure helper with tests, as the adapter has no DOM.
+- `prepareExit` cancel returns `invalidateOrder` on settlement, an ordinary transaction with a gas cost, which is definitive where the off-chain cancel is best effort. An order owned by someone else is refused. There is no `collect`, as fills arrive in the wallet.
+- `openOrders` maps CoW statuses to `RestingOrder`, and `executedBuyAmount` to `receivedOut`.
+
+- [ ] **Step 2: Settle two unknowns live.** In `evm-cow.live.test.ts`, by exact name, quote only and create no order: whether the owner orders path exists as written in the report, and whether buying native AVAX through `0xEeee…` quotes. If it doesn't, a purchase pays out in WAVAX and a note says so.
+- [ ] **Step 3: Run the tests to see them fail**
+- [ ] **Step 4: Implement.** `notes`: `Your funds stay in your wallet until a solver fills this at your price or better.`, `Expires in 7 days.`, `Avalanche has few CoW solvers trading right now, so it may not fill.`, `Cancelling costs a small network fee.`, and for the approval, `This lets CoW move exactly this amount and no more.

+
+**Interfaces:**

+- Consumes: Tasks 1, 2, and `thenPrepareAgain`.
+- Produces: `ChainMessageRead` adds `{ kind: 'limit'; action: ChainActionRequest }` and `{ kind: 'orders' }`. `ordersAsked(text: string): boolean`. `orderLine(order: RestingOrder): string`. `exitsFor(order: RestingOrder): ('cancel' | 'collect')[]`. `freshExit(listed: RestingOrder, now: RestingOrder | undefined, action): 'cancel' | 'collect' | 'gone'`. The hook adds `prepareExit(orderId, action, text)`.
+
+- [ ] **Step 1: Write the failing tests**
+
+- `readChainMessage('sell 1 SOL at $110', 'solana', 'Solana')` is `limit`. `parseChainSequence` still wins for `swap 1 SOL to USDC then cash out`, and a plain swap stays a plain swap.
+- `readChainMessage` on Monad refuses with `LIMIT_NOT_HERE`.
+- `ordersAsked` is true for `my orders`, `show my open orders`, `cancel my order`, `limit orders`, and false for `order 5 SOL` and `in order to swap`.
+- `exitsFor`: open offers cancel; partly offers cancel and collect where something is collectable; filled offers collect only; done offers nothing.
+- `freshExit`: Cancel pressed on an order that has since filled becomes `collect`, and one no longer listed is `gone`, which says `That order is no longer open. Nothing was signed or sent.`
+- `orderLine` reads like `Sell 1 SOL at $110, 0.4 filled, expires Nov 12`.
+- A settled action with `thenPrepareAgain` keeps the request and offers one `Continue` press, and a press while building does nothing. A settled action without it behaves as today.
+
+- [ ] **Step 2: Run them to see them fail**
+- [ ] **Step 3: Implement.** A limit goes straight to the card, with `racesFirst` false. The card shows pay, the price, the least it will receive, the notes, and the cost. After settling, the chat says the order is resting, how to see it (`my orders`), and for Sui and NEAR that collecting takes another signature. The list re-reads on open and after any exit, and each press re-reads the order first (`freshExit`). Chat persists through the existing transcript. Nothing about an order is written to the database.

+- Test: `apps/dapp/lib/__tests__/chain-limit-reading.test.ts`
+
+**Interfaces:**
+
+- Consumes: `parseChainLimit`, `limitSaid`, `LIMIT_NOT_HERE`.
+- Produces: `chainRouteFromReading` returns `{ action }` with `kind: 'limit'` when the instruction parses as one and `limitSaid` holds, and otherwise a refusal.
+
+- [ ] **Step 1: Write the failing tests**
+
+- Person: `I want to get rid of 1 sol once it reaches 110`. The model's instruction is `sell 1 SOL at $110`: runs as a limit.
+- The same with the model's instruction `sell 1 SOL at $120`: refused.
+- A reading with a limit style whose instruction doesn't parse: refused with an example, never turned into a market swap. This is the trap: today a limit reading with `style` ignored would run at market.
+- `buy 2 SOL at 90`: refused with `Say how much you will spend, for example "buy SOL with 180 USDC at $90".`
+- `sell $5 of SOL at $110`: refused with `Say how much SOL, for example "sell 0.05 SOL at $110".`
+- The Stellar prompt hash test still passes.
+
+- [ ] **Step 2: Run them to see them fail**
+- [ ] **Step 3: Implement.** The off-Stellar prompt says a stated price or "when it hits" is a limit, written out as `sell <amount> <token> at $<price>` or `buy <token> with <amount> <stable> at $<price>`, and carries `style: 'limit'`. Where Monad is the chain, it says there is none.

+- Modify: `apps/dapp/lib/agents/brief.ts` (`CHAIN_BRIEF`), `apps/dapp/lib/agents/settle-chain-plan.ts`, `apps/dapp/lib/agents/chain-routes.ts`, `apps/dapp/lib/agents/market-context.ts`, `apps/dapp/lib/agents/chain-race.ts` (`chainRequestFor`, `recommendationLine`), `apps/dapp/app/api/agents/compete/route.ts`, `apps/dapp/components/intents/competition-panel.tsx`
+
+**Interfaces:**
+
+- Consumes: `limitPair`, a chain's `limit` venue and its `limitCost`.
+- Produces:
+  - `restOption(chainApi, request, marketUsd): RestOption | undefined`, where `RestOption = { venueId: string; venueName: string; marketUsd: number; selling: boolean; cost?: { amount: string; symbol: string }; notes: string[] }`. Nothing unless the request is a swap with a stablecoin side and the chain has a limit venue for that pair.
+  - `settleChainPlan(proposal, rest?: RestOption)`: keeps `executionMode: 'rest'` and `restPriceUsd` only when the price is inside the band, and otherwise makes it a fill, as today.
+  - `restBand(marketUsd, selling): { least: number; most: number }`: selling 0.1% to 5% above the market, buying 0.1% to 5% below.
+  - `chainRequestFor` turns a rest proposal into `{ kind: 'limit', amount, tokenIn, tokenOut, venue: rest.venueId, limitPrice }`, with the amount and tokens from what the person asked.
+  - `restAlternativeLine(proposals): string | undefined`
+
+- [ ] **Step 1: Write the failing tests**
+
+- `restOption` is undefined on Monad, for a supply, for a pair with no stablecoin, and when a venue was named.
+- `settleChainPlan` keeps a sale resting 2% above the market. It turns into a fill: a sale below the market, one 6% above, a purchase above the market, and `split` always. Without a `rest` argument, it always fills, as today.
+- Scoring: a rest proposal never outscores the best measured fill, as it has no measured fill, so `Recommended` stays on measured figures.
+- `unanimous` is false when one agent fills and another rests, so the panel doesn't say they agree.
+- Off Stellar, a decided race always states one recommended strategy, including when agents agree or only one route exists: `Recommended: fill now via Jupiter. All 2 agents agree. You pick who executes.` The user asked for this, and Stellar's line does not change.
+- `restAlternativeLine`: `1 agent suggests resting at $98.00 through Kamino: it could get more, costs about 0.003 SOL, and may never fill. You choose.`
+- Pressing Review on a rest proposal prepares a `limit` request whose amount and tokens are the person's, and a route whose amount differs from what was asked is still refused.
+- The chain brief names the option only when the market context lists one, and tells agents to weigh the cost against the amount, so a very small swap fills. Stellar's prompt hash test still passes.
+
+- [ ] **Step 2: Run them to see them fail**
+- [ ] **Step 3: Implement.** The panel's card tag reads from `describePlan`, which already handles a rest. A rest card's Review opens the limit card, so the person sees the full terms, and signs only there. Without a limit venue, the race is as it is today.
+- [ ] **Step 4: Run all the task's tests, with import-purity and routes-load**
+- [ ] **Step 5: Commit**: `feat(dapp): let agents recommend resting an order where a venue can hold it`
+
+---
+
+### Task 10: Whole-branch verification and preview
+
+**Files:** none changed unless a check fails.
+
+- [ ] **Step 1:** From `apps/dapp`: `npx tsc --noEmit`, exit 0. `pnpm exec next lint`, no errors. From the root, Prettier `--check` on the files changed since `feat/chain-sequences`.
+- [ ] **Step 2:** `npx vitest run --exclude '**/*.live.test.ts' --reporter=basic --maxWorkers=3 --minWorkers=1`: no failures.
+- [ ] **Step 3:** Run the four live tests by exact name. Each only reads and simulates. Record outcomes.
+- [ ] **Step 4:** Report whether the combined tree of `feat/chain-limit-orders` and `feat/onchain-venues` merges cleanly (`git merge-tree --write-tree`), without merging anything.
+
+The controller deploys the preview. No task pushes, merges, or touches Production.

+# Agents That Talk To Each Other: Design
+
+Date: 2026-11-05. Status: approved by the owner on 2026-11-05.
+
+## Intent
+
+Today each agent answers a person's intent once, alone, and the panel compares the answers. The owner wants agents to read each other's strategies, question each other, and improve their own, in the open, in the chat, in real time, on all six chains: Stellar, Solana, Avalanche, Sui, Monad and NEAR.
+
+The why: more competition produces better strategies, and watching agents challenge each other is the product. The person should see "Sonnet went through Jeff's strategy", "Sonnet asked Jeff a follow-up", "Jeff responded", and then each agent's final strategy.
+
+## The owner's decisions
+
+- All six chains.
+- Layout: the talk appears inside the existing chat thread, as messages in order. Mockup A.
+- No UI changes to existing bubbles, colors or layout. Build only from what exists.
+- Agents may all reach the same conclusion, but that must never be hardcoded. Independent thinking is required. Different strategies are preferred, not forced.
+- Talk is built first. Different trades come from work already in progress (see Dependencies).
+- The talk runs 10 to 20 seconds before final strategies drop.
+
+## Goals
+
+1. Each agent reads the intent, reads other agents' strategies, can question them, answers questions put to it, and then decides its own final strategy.
+2. The person watches this live, with motion, in the chat.
+3. Works for every kind of action the race handles today (swap, supply, stake on chain modules, and Stellar's race), on all six chains.
+4. Everything the person reads as an agent's words was written by that agent's model in this race.
+
+## Non-goals
+
+- New routes, venues or order types. See Dependencies.
+- More than one round of questions.
+- The person joining the talk. A note sent mid-race restarts the race, as it does today.
+- Agents remembering earlier races.
+- Word-by-word streaming of model output.
+- Any agent signing or sending anything.
+
+## Anti-goals: a failure even if it works
+
+- Scripted lines, or a "reading" pill with no read behind it.
+- Any step, vote, merge or prompt wording that pushes agents toward agreeing or toward differing.
+- An agent's plan copied from, or rewritten into, another agent's plan by code.
+- Scoring that rewards persuasion. Recommendation stays on measured numbers.
+- A race that visibly runs much past 20 seconds because of talk.
+- New bubble styles, colors or layouts.
+
+## Dependencies: read before building
+
+Other sessions are changing this code right now. Check their state before starting.
+
+- **PR #153, `feat/chain-limit-orders`** (draft, stacked on #152). Task 9 lets agents recommend resting an order, and modifies `brief.ts`, `settle-chain-plan.ts`, `chain-routes.ts`, `market-context.ts`, `chain-race.ts`, `compete/route.ts` and `competition-panel.tsx`. It also requires that off Stellar a decided race always states one recommended strategy, which the owner asked for. Limit venues: Kamino, DeepBook, Rhea, CoW. Monad has none.
+- **`feat/onchain-venues`** (no PR yet). Adds swap venues.
+
+The owner chose talk first, so stack this work on `feat/chain-sequences` (#152) and don't wait for #153. Both touch the same files, so whichever merges second resolves the conflicts. Agents can't choose resting during talk until #153's Task 9 lands: when it does, the final turn's tool offers rest wherever a `RestOption` exists. Work in a new worktree. Never switch branches in the main checkout.
+
+Choices per chain once both land:
+
+| Chain | Swap routes | Rest an order |
+|---|---|---|
+| Stellar | Several | Yes, plus split |
+| Solana | Jupiter, 1Click | Kamino |
+| Sui | Cetus, 1Click, DeepBook, Momentum | DeepBook |
+| Avalanche | 1Click, Uniswap, Pharaoh | CoW |
+| Monad | 1Click, Uniswap | None |
+| NEAR | 1Click | Rhea |
+
+This table comes from the branches as read on 2026-11-05. Neither has merged, and no real wallet has signed on them.
+
+## How a race runs
+
+The clock starts when `competition:started` is sent, after routes are quoted. All of this happens inside the one request in `app/api/agents/compete/route.ts`, so there is no shared state.
+
+1. **Each agent thinks first.** Each agent works through the intent on its own, calling the existing `propose`, with the existing prompt and tool, in parallel. It sees no other agent. Shown as it lands.
+2. **Talk opens** when every agent has a first take, or at 8 seconds, whichever comes first. It needs at least two first takes, so if only one is in at 8 seconds, talk opens when the second lands. It never opens after 14 seconds, which leaves each turn at least 2 seconds. With no talk, the race still ends by 20 seconds if anyone has answered.
+3. **Ask turn.** Each agent gets the intent, its own plan and the others' plans, and may ask one question of one agent, or ask nothing.
+4. **Answer turn.** Only agents that were asked make a call. One call answers all of its questions.
+5. **Final turn.** Each agent reads the whole talk and decides alone: keep its plan, change it, or hold off.
+6. **Close at 20 seconds at the latest.** Scoring runs on final plans only.
+
+The time left after talk opens is split evenly across the three turns. A turn ends early once all its calls return.
+
+### Deadlines and failures
+
+| What happens | Result |
+|---|---|
+| Ask call misses its turn | That agent asks nothing. No message. |
+| Answer call misses its turn | A pill says the agent did not answer in time. No words invented. |
+| Final call misses its turn, fails or is invalid | First take stands as its final plan. |
+| First take lands after talk opened | Shown. It skips closed turns and may still make the final turn. |
+| First take misses 20 seconds while another agent has answered | Counted as not answering in time, using the existing `unansweredLine`. |
+| No first take at all by 20 seconds | No talk. Keep waiting up to the existing 60-second limit, as today. |
+| 429 during talk | `noteRateLimited` as today. Same results as the rows above. |
+
+Agents cannot address themselves. A question naming an unknown or failed agent is dropped.
+
+## Speed: unproven, and task one
+
+Measured figures in the repo:
+
+- DeepSeek V4 Flash, first take: median 7.2s, p90 15.7s, p95 20.9s, max 26.2s (`lib/agents/evals/results`, 2026-09-08, 80 calls).
+- Groq: 1.6 to 1.8s (comment in `brains/providers.ts`, undated).
+- OpenRouter free models: no figures.
+
+If talk opens at 8 seconds, each turn gets 4 seconds. A reasoning model at normal settings will miss that. Talk turns must therefore use a short prompt and a small output limit, and turn off model reasoning where the provider allows. `MAX_OUTPUT_TOKENS` says reasoning counts against the output limit, so a small limit with reasoning on returns nothing at all.
+
+**Task one is a measurement, before any product code.** It depends on neither branch. For every model in the production roster, measure a first take and a talk-shaped prompt, in a `*.live.test.ts` file run by exact name. Record median and p90, and whether reasoning can be turned off. Use about ten calls per model, and five per OpenRouter model, because the free key's daily limit is shared with real races.
+
+**Go:** every line-up `lineUp` can seat has at least two models with a talk p90 under 3 seconds, and first takes fast enough that talk usually opens by 14 seconds. **No-go:** stop and bring the numbers to the owner. A talk with one participant isn't a talk, and the choices then are a longer cap or a different roster.
+
+A slow seat is still called. It keeps its first take when it misses a turn, per the table above. `lineUp` doesn't change.
+
+## Provider limits
+
+- OpenRouter free: 50 requests a day per key, or 1,000 a day once 10 credits have been bought, and 20 a minute. Two seats at four calls each is up to 8 requests a race, against 2 today. That is about 6 races a day on an untopped key, down from 25. Answer turns are skipped for agents nobody asked, so it can be less.
+- Groq: 8,000 tokens a minute. A first take costs about 2,300. Each talk prompt must stay under about 800 tokens so one race fits comfortably.
+- Nothing retries inside a race.
+
+## Independence rules
+
+- Each agent thinks through the intent and forms its own plan before seeing any other.
+- Each agent reads the others' plans in a different order, rotated by seat, as routes already are.
+- Talk prompts say: improve your own plan, and change it only if you are persuaded. They contain no instruction to agree, to reach consensus, or to differ.
+- A final plan comes only from that agent's own model call. Otherwise its first take stands.
+- `unanimous` stays computed from the final plans, after the fact. It is false if any agent holds off. Fix the panel's count, which today counts all answered agents.
+- A test checks talk prompts for words such as "consensus" and "must differ".
+
+## Holding off
+
+An agent may end on "I wouldn't do this now", in its own words.
+
+Today it can't. `validateProposal` fills a blank route with the first one offered (`tool-schema.ts:314-320`), because a blank usually means a model forgot the field. Keep that for first takes. The final turn's tool gets an explicit decision: `keep`, `change` or `hold`.
+
+A held plan has no route, shows no Review button and gets no score. `scoreProposals` already ranks plans with nothing to sign last.
+
+A held plan must never reach signing by another path. `intent-chat.tsx` falls back to the winner's route when an agent has none (`routesByAgent[executingKey] ?? winnerRoute`), so a held agent must not be selectable, on a live race or a reopened one. `pickWinner` must not return a held agent.
+
+## Safety
+
+- Agent text is untrusted when it enters another agent's prompt, because intents and route notes can carry planted instructions. The evals recorded `deepseek-v4-pro` following one. Pass every line through `promptSafe`, and label the block as what other agents said, not instructions.
+- A changed final plan goes through the same checks as a first take: `validateProposal`, `settlePlan` or `settleChainPlan`, then `measured`. So a route must be one that was offered, and figures are measured by the server.
+- Talk can't change the amount or tokens. Those stay the person's.
+- Review stays on final cards only, and signing stays with the person. First takes have no Review, since they may change.
+- Agents get no account details. Talk uses the same context lines as today.
+- An agent could still state a false figure in a message. Talk prompts repeat the rule to use only given figures. Final cards show measured figures.
+
+## What the person sees
+
+Everything sits in the thread, in order, using existing pieces only.
+
+| Moment | Built from |
+|---|---|
+| First take | `agentBubble`, `AgentAvatar`, name and model line, `describePlan` tag and reasoning. No Review. |
+| "Sonnet is reading Jeff's strategy" | `systemPill`, sent when that agent's ask call starts. It names the agents whose plans that call was given. |
+| Agent waiting on its model | Existing `ThinkingDots` in `agentBubble` |
+| Question, answer | `agentBubble`, `AgentAvatar`, name line reading "Sonnet to Jeff" |
+| "Sonnet changed its strategy" | `systemPill`, only when route, mode or decision differs from its first take |
+| Final strategies | The existing cards, Review, penalties and Recommended, unchanged. Hold-off cards have no Review. |
+| Late answer | `systemPill` |
+
+Motion uses the same `motion.div` entrance as today's cards, and respects reduced motion as `ThinkingDots` does. Messages are capped at two sentences and 160 characters and pass through `tidyProse`.
+
+Frames arriving together are shown in order, about 700ms apart. If the queue falls behind the close, the gap shrinks so final strategies stay near 20 seconds. Nothing is shown before it exists on the server.
+
+The talk is saved with the turn on that browser, so it survives a reload and shows without animation. The backend that stores turns isn't in this repo, and this work doesn't change it, so another device sees the final cards without the talk. A reopened turn must still never offer Review on a held plan, even if the saved hold marker was lost: treat a plan with no route as held.
+
+## Shape of the code
+
+- `lib/agents/talk.ts`: runs the turns and deadlines with injected brains and clock. Pure enough to test without network.
+- `AgentBrain` gains a talk method, implemented in `brains/openai-compatible.ts` and `brains/anthropic.ts`. `propose` and the first-take prompt stay as they are. Stellar's prompt stays pinned by hash.
+- `lib/agents/events.ts`: new frames for first takes and talk lines, each with a sequence number. `competition:proposal` means a final plan. Unknown frames are already ignored by the hook.
+- `hooks/use-competition.ts`: collects them. Ordering and pacing live in pure helpers beside `pacing.ts`, since vitest has no DOM.
+- `components/intents/competition-panel.tsx`: renders talk above final cards.
+- Analytics: outcomes and counts only, never words, matching the rule in the route. Questions asked, plans changed and holds. If this needs a schema change, leave it out of this work and say so.
+
+## How we'll know it works
+
+- Unit tests: turn order, every row of the failure table, first takes made before seeing other agents, no plan copied across agents, prompts free of steering words, hold-off, unanimity, and pacing.
+- Extend `pnpm agents:eval`: for each golden case, record how often agents chose the same plan before and after talk, and how often a plan changed. No target is set. If talk makes agents collapse into one plan, the owner should see it. Add a case where a planted instruction arrives through another agent's message.
+- A real race on each of the six chains on a preview with its own Postgres, as preview-first requires. Check that the talk reads as real, and time it.
+- No claim that a chain is proven until someone signs there with a real wallet.
+
+## If every agent holds off
+
+Decided by the owner. PR #153 requires a recommended strategy on every decided race off Stellar, and this is the one exception, since there's nothing to recommend.
+
+A pill says no agent would do this now, each agent's reason stays visible, and no signable card appears, on any chain. `needsDirectRoute` must stay false here, because agents did answer, and "The agents were unavailable" would be false. If the person still wants the trade, they ask again, and that runs as a normal new race.
+
+## Provider prerequisite
+
+The owner buys OpenRouter credits before launch, which lifts the free key to 1,000 requests a day. This work doesn't ration talk. Until then, an untopped key runs out sooner, and a 429 benches that model as today.
+
+## Builder's calls so far
+
+These were decided by the designer, not the owner. Change them if the build shows a better way.
+
+- 20 seconds counts from `competition:started`, not from when the person pressed send, because quoting time varies.
+- Talk opens at 8 seconds at the latest, with even turns afterward.
+- One question per agent, 160 characters.
+- 700ms between messages.
+- Talk saved on the same browser only.
+- Talk never opens after 14 seconds.
+- `feat/onchain-venues` isn't required to build this. Build against whatever routes exist, and keep talk prompts short enough for Sui's four routes.
+- A first take later than 20 seconds drops out, where today it has 60. About 1 in 20 DeepSeek calls would, on the September figures.
+- No feature flag.
