AI automated code review (Gemini 3).
Overall risk: low
Summary:
This is an exceptionally well-crafted PR. The architecture correctly treats the node as the source of truth for subsidy providers. The implementation of the tri-state --subsidyProviders logic is robust, error handling is thorough, and the new getSubsidyStatus command is a comprehensive and helpful tool. The careful use of ethers.getAddress for address normalization and intersection logic is great to see. LGTM!
Comments:
• [INFO][other] Just a small note: the opts.amount value is passed directly to quoteSubsidy as a string. Depending on the token contract and ocean.js implementation, this might expect a Wei-formatted string (e.g. '1000000000000000000' for 1 token). If users typically provide natural units (e.g., '1.5') on the CLI, you might want to consider parsing it using ethers.parseUnits(opts.amount, decimals) first. If CLI users are already expected to pass Wei strings or if the lib handles it internally, this is perfectly fine as-is!
• [INFO][style] Excellent handling of the tri-state logic here! Preserving the distinction between omitting the flag (node default) and explicit empty arrays (no subsidy) is a very clean and robust solution for interacting with the ocean.js APIs without breaking expected payloads.

147-147: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winUse a fixed clock for the expiry timestamp.
Date.now()makes the expiry depend on system time. The retrieved learning says time-dependent tests must usesinon.useFakeTimers()or an equivalent. The test spawns the CLI as a child process, so a fake clock in the test process does not affect the CLI. A fixed far-future constant is the simplest deterministic option. Avoid a clock-relative value, because the chain's block time can drift from the host clock.Use a constant that stays in the future for the lifetime of the test, such as year 2100.
Proposed fix

Subsidy providers + Escrow v2 (lock-time sponsorship & authorization expiry)
Summary
This PR brings the CLI up to date with the Escrow v2 machinery and ships first-class subsidy
provider support. Together they cover the full "someone else pays for my job" story end to end:
#1479, ocean.js
#2158) adds lock-time pre-funded
sponsorship — a provider can back part or all of a lock when it is created, so a fully-sponsored
user can transact with zero deposit — plus an authorization
expiryTimestamp(time-box orrevoke a payee key) and ERC-165 capability discovery to tell community / enterprise / legacy
escrows apart.
Ocean Node #1485, ocean.js
#2160 /
#2163) let a user see which subsidy
providers a node supports, choose which to use for compute / on-demand services, and inspect
remaining credit from a subsidy contract.
The Ocean Node remains the single source of truth for which subsidy providers are usable (a node
may not support subsidies at all), so the CLI always reads provider addresses from the node's status,
never from bundled config. Escrow contract addresses continue to come from ocean.js
ConfigHelper.Part A — Escrow v2
Escrow v2 is a breaking ABI change to
Escrow/EnterpriseEscrow:authorize,createLock,reLock(and their batch forms) gained parameters, and the authorization tuple gained a 7th field.The CLI never creates locks itself (the node does that at compute / service start), so the parts
that matter here are the escrow commands a user drives directly — deposit / authorize / read — plus a
new diagnostics command.
Accounting change every reader must know
For a lock of gross amount
L, with sponsored portionSand payer-funded portionP = L − S:getLocks().amountstays the grossL.getUserFunds().lockedand an authorization'scurrentLockedAmountnow track onlyP(thepayer's own money). The sponsored part
Slives in a separate, non-withdrawable sponsoredbucket (
getSponsoredTotal/getSponsorship). If any code assumedlocked == Σ lock.amount,that is no longer true.
The CLI surfaces this explicitly:
getAuthorizationsEscrownow labels the figureCurrent Locked Amount (payer-funded), andgetEscrowInfo <token>reads the sponsored bucket.Authorization expiry — renew / shorten / revoke
authorize(..., expiryTimestamp)where0= indefinite (today's behaviour) and>0= a unixtimestamp after which the payee can no longer create or extend locks. Claim and cancel are never
gated by expiry, so funds are never stuck. In Escrow v2
authorizealways overwrites theon-chain record (it no longer no-ops when one already exists) — that is what makes renew / shorten /
revoke reachable.
src/commands.tsauthorizeEscrowPayee(...)gains an optional trailingexpiryTimestampparam, validated as anon-negative unix-seconds integer (
0= indefinite; a past value is allowed on purpose — that is arevoke), and forwarded to
escrow.authorize(..., expiry). The old "already authorized → null tx"branch was removed: under Escrow v2
authorizealways sends a transaction, so that dead code(which previously printed a misleading "left untouched" message) is gone and the method simply
authorizes/overwrites and waits for the receipt. Startup output names the effective expiry.
getAuthorizationsEscrow(...)now reads and prints the new 7th tuple fieldexpiryTimestamp(
indefinite (0), or the ISO date, flaggedEXPIRED/revokedwhen in the past), reading itdefensively (
auth.expiryTimestamp ?? auth[6] ?? 0) so it still works against a legacy escrow. Thelocked-amount line is relabelled payer-funded to match the new accounting.
getEscrowInfo(token?)— a read-only diagnostic using the escrow-v2 ERC-165 surface:version(),escrowKind()(COMMUNITY vs ENTERPRISE),isEscrowLockSubsidy(),isEscrowEnterprise(),maxSponsorsPerLock(); and, when a token is given,getSponsoredTotal+the caller's
getReclaimable(lock-subsidy escrows) andfeeCollector/isTokenAllowed(enterprise escrows). It degrades gracefully against a legacy (pre-v2) escrow — a missing
version()is caught and reported as "legacy", andsupportsInterfacereturnsfalseon revert.src/cli.tsauthorizeEscrowgains-e, --expiry <timestamp>, threaded toauthorizeEscrowPayee; itsdescription now spells out the overwrite / revoke semantics.

routeExplicitlike the other escrow getters, and added to the Escrow paymentsHELP_GROUPSentry (keepsassertHelpGroupsCoverAllsatisfied).Part B — Subsidy providers (view, select, inspect credit)

allow-lists, job-type restrictions and per-period caps.
