Summary by CodeRabbit
New Features
Added paid peering with invoices, payment-gated feed access, renewal billing, and payment checks before access lapses.
Peering subscriptions now close when paid access expires. Access can resume after payment, and peer events and sync state are retained.
Added billing status and access-period details to the admin dashboard, along with notifications for peering invoices, payments, failures, and lapsed access.
Added validation for paid peering terms, payment settings, and supported payment units.
Documentation
Documented paid peering requirements, supported payment units, and the invoice and renewal flow.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
The changes add paid-peering invoice creation, settlement, renewal, and lapse processing. They gate peer feed requests on billing access, retain sync state when access lapses, and display billing details in the admin peering endpoint and dashboard. They also validate paid-term settings and document the invoice and access flow.
Adds invoice purpose and term fields, peering-payment storage, repository contracts, conversion helpers, and paid-term validation. Settings and documentation describe paid peering and notification events.
Peering invoice creation and settlement src/services/payments-service.ts, src/factories/payments-service-factory.ts, test/unit/services/payments-service.spec.ts
Creates peering invoices with term snapshots. Confirmation records paid periods, underpayments, and duplicate settlements, and publishes tagged invoice notifications.
Peer subscription requests can issue invoices. Peer subscriptions, COUNT requests, and NIP-77 reads check billing access before processing. Subscription expiry timers recheck access and close subscriptions when access ends.
cameri/nostream#939 — The PR adds billing status, access end, invoice details, and error data to the admin peering surface, which addresses part of the issue’s requested visibility.
cameri/nostream#931 — The PR adds renewal invoices, lapse suspension, retained sync state, and access restoration through payment settlement.

cameri/nostream#1043 — This PR extends its admin peering contracts and dashboard with billing state.
Merge Risk: Moderate · previous review 59b23
Paid peering can still misreport or mishandle billing in several edge cases. The admin endpoint may fail to serialize a term amount. A repeated callback for an older invoice may extend access twice. A concurrent settlement can be overwritten by a processor re-check. Peers beyond the first renewal page may lapse without a renewal invoice. A lapse can clear a payable renewal invoice. These should be addressed before merge.
Security architecture risk: Moderate · up to 59b23
The main feed gate is preserved in the inspected request paths, but payment recovery and database rollback have meaningful risks. Interrupted or concurrent processing can strand a paid peer’s access, and downgrading can misclassify unsettled peering payments as user-balance payments.
Retained concerns
Medium · reliability · inferred: Payment status, settlement, and expiry do not form one recoverable entitlement transition. The worker persists completed status before confirmation; interruption or confirmation failure then removes the invoice from pending-only polling, and the new peering recheck also refuses non-pending invoices. Separately, handleInvoiceExpired can read an invoiced peer, allow settlement to commit, and then overwrite the committed access window and settlement markers with its stale whole-row snapshot. Settlement locks protect its own transaction but do not protect this expiry writer. The confirmed-invoice duplicate guard can subsequently prevent reapplying the lost grant. The status-ordering weakness predates this PR, but this PR newly makes it govern paid peer access; the stale expiry writer is new. Both paths can leave payment recorded without the corresponding access entitlement.
Medium · security · inferred: The new down migration drops the peering ledger, restores confirmation that credits user balances without checking payment purpose, and removes the purpose discriminator while retaining invoice rows. If an unconfirmed peering invoice is settled after downgrade and a corresponding user exists, that payment can enter ordinary user-balance accounting instead of peering settlement. Already-confirmed invoices retain duplicate protection, so this concern is limited to unsettled or interrupted payments and requires an operator-triggered rollback. It is a new cross-purpose accounting failure mode; deployment controls that drain or quarantine outstanding invoices were not established.
Security review details
Security Blast Radius
inferred — The supported failure scope is the affected relay’s peer entitlements and invoice accounting. Transition failures can strand individual paid relationships; rollback can affect outstanding peering invoices and matching user balances. The inspected evidence does not establish cross-environment authority or credential exposure.
Security Findings and Attack Paths
inferred — A processor-confirmed payment can lose its access grant through interruption between status persistence and settlement, or through a stale expiry write after settlement. These are fault and concurrency paths affecting the integrity of authorization state; the inspected paths do not demonstrate an attacker obtaining unpaid ordinary-feed access.
Trust Boundaries and Controls
observed — The invoice exception requires exactly kind 402 and inclusion of the authenticated key and peering topic, but inclusion is not exclusive: a mixed-recipient filter can match another peer’s invoice under OR tag matching. This does not admit ordinary event kinds. Invoice events already used public persistence and broadcast before this PR, and the read guard enforces recipient authorization when kind 402 is configured as restricted. A recipient-confidentiality requirement is therefore unresolved, rather than a verified new disclosure finding.
Resilience and Maintainability Implications
observed — Stored invoice confirmation and last-settled identity prevent repeated period grants, and settlement rejects underpayment using the stored term snapshot. These controls contain replay and underpayment, but also make automatic repair of an overwritten grant dependent on a recovery path distinct from ordinary duplicate settlement.
Hardening Proposals
proposed — Use one recoverable settlement protocol for invoice completion and entitlement activation, reconcile completed-but-unconfirmed invoices, and make expiry a locked or conditional update that cannot overwrite a newer settlement.
proposed — Gate downgrade on draining or quarantining unsettled peering invoices, or retain enough purpose information to prevent their later confirmation from entering user-balance accounting.
proposed — If invoice-only access is intended to mean only the authenticated peer’s invoices, require exclusive recipient scoping or enforce it at delivery, and document whether invoice metadata is public or recipient-restricted.

Explanation
The title "feat(peering): renew, lapse and expose paid peering access" matches the main change in the changeset. The diff adds paid peering invoices, renewal invoices before period end, lapse handling that closes peer sockets, and billing details in the admin endpoint and dashboard. The title names the primary feature and its three main parts, so it is specific and not vague.
Full details: Out of Scope Changes check
Explanation
Each changed area maps to #937 or to direct support for its objectives. Mapped areas: the peering_payments migration and invoice purpose and term snapshot fields. The confirm_invoice() change keeps peering invoices from crediting user balances. PeeringBillingService, PeeringPaymentRepository, and src/utils/peering-billing.ts handle invoice issuance, renewal, and lapse. Subscribe, COUNT, and NEG-OPEN access checks include the canSubscribe exemption for invoice requests. PeeringRevoke closes live peer sockets. GET /admin/peering, mergePeeringRows, the dashboard, and admin-ops.js provide admin visibility. Settings validation covers paid terms and default notification toggles. docs/PEERING.md, default-settings.yaml, changesets, and unit tests support these areas. The t tag and the example amount change in default-settings.yaml support the invoice flow. No changed area lacks a connection to #937 or to the paid-peering work described in the PR. This result covers the whole-PR summary and the auth-message-handler file at head. The incremental diff since the previous reviewed heads was not read, so this result carries that uncertainty.

Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 0 functions across 44 files.
Full details: Linked Issues check
Explanation
[#937] requires the source relay to issue a BOLT11 invoice when a configured peer with paid terms authenticates. The acceptance flow is authenticate, then invoice, then settlement, then feed access for the paid period. At the reviewed head, src/handlers/auth-message-handler.ts is unchanged from the merge base (whole-PR diff is empty). After NIP-42 AUTH succeeds, the handler calls only this.webSocket.setPeerPubkey(event.pubkey) for configured peers. It does not call PeeringBillingService.ensureInvoice or any other billing path. The whole-PR summary shows no other authentication-triggered invoice path. Invoice issuance is request-driven: SubscribeMessageHandler calls ensureInvoice for a kind 402 REQ with a #t ["peering"] filter. docs/PEERING.md describes the same request-driven flow. The following parts are implemented in the whole-PR summary: settlement in PaymentsService, period extension through peering_payments.period_end, renewal before period end, lapse with socket closure that keeps events and sync state, admin visibility, and unit tests. Test execution was not verified. The incremental diff since the previous reviewed heads was not read, so this result uses the whole-PR diff, the summary, and the auth handler file at head.
Resolution
Call PeeringBillingService.ensureInvoice for a configured paid peer from the authentication path in src/handlers/auth-message-handler.ts, after setPeerPubkey. Add a unit test that asserts an invoice is created on successful AUTH without a prior kind 402 REQ. Alternatively, if request-driven issuance is the intended design, change the scope and acceptance criteria of #937 to state that design, and then reassess. Until one of these is done, this PR does not meet #937 as written. #937 should not be closed by this PR.

Review comments at @src/services/payments-service.ts:
- Around line 392-395: Update the duplicate-settlement guard in the payment
callback flow to treat the invoice’s stored periodEnd as evidence that its
period was already granted, alongside the existing lastSettledInvoiceId check.
Do not use confirmedAt as the settlement marker, since it can also indicate an
underpayment.
Review comments at @src/services/peering-billing-service.ts:
- Around line 269-282: Update recheckPendingInvoice and handleInvoiceExpired so
their unlocked full-row saves cannot overwrite concurrent settlement fields;
persist only lastCheckedAt and lastError using an established targeted-update
path. If a full-row save is necessary, perform it under lockByPeer and re-read
the row inside the transaction before saving.
- Around line 361-371: Update handlePeriodEnded so it retains pointers to
renewal invoices that are still pending and unexpired, and clears only pointers
to invoices confirmed expired or completed. Use the existing invoice state and
expiry checks so ensureInvoice continues to avoid creating a duplicate and
recheckPendingInvoice can still find the pending invoice.
- Around line 464-468: Update the offset advancement in sweep so handled renewal
rows count toward the offset because they remain in findDueForRenewal’s result
set after handling. Preserve the existing ended-sweep behavior, where handled
rows leave the result set.
Review comments at @src/utils/admin-peering.ts:
- Line 37: Serialize non-null `payment.termAmountMsats` as a string before
including it in the `GET /admin/peering` response, preserving null when no term
amount is present. Update the response type and test expectations to match, and
add an assertion that the response serializes successfully.
Review comments at @src/utils/peering-billing.ts:
- Around line 88-105: Update isPeeringInvoiceRequest to return true only for a
non-empty filter list where every filter passes isPeeringInvoiceFilter. In
isPeeringInvoiceFilter, require the #p list to contain exactly peerPubkey and no
other pubkeys; preserve the existing invoice-kind and peering-topic checks.

Add tests for the billing failure paths in enforcePeeringAccess.
The new tests cover denied access, a valid invoice request, a mixed request, an abort during billing, and expiry scheduling. They do not cover these paths:
ensureInvoice rejects with PeeringInvoiceCooldownError. Expect CLOSED with rate-limited: peering invoice reissue cooling down and retryAfterSeconds * 1000 as a string.
ensureInvoice rejects with a generic error. Expect CLOSED with error: unable to issue peering invoice.
getAccess rejects. Expect CLOSED with error: unable to check peering access, with no fetch.
These paths decide whether a peer's feed opens or closes. They also match the uncovered lines in the Coveralls report.

Paid invoices can get stuck
The maintenance worker saves COMPLETED before calling confirmInvoice. If that transaction fails, the invoice stays completed but grants no access. The worker only scans pending invoices, and this check also rejects completed invoices, so polling-only processors cannot recover the payment. A later invoice request can produce another bill.
Save the status and grant access in one transaction, or retry completed invoices whose confirmedAt is still empty.
The reason will be displayed to describe this comment to others. Learn more.
Sync outlives paid access
An open NIP-77 session can keep returning event IDs after paid access ends. NEG-OPEN checks payment once but installs no expiry check. Later NEG-MSG requests check only read permissions, and active messages restart the idle timer. The peer can continue syncing until the maintenance worker closes its socket.
Recheck paid access on NEG-MSG, or attach an expiry check to the session.
How this was verified:NEG-OPEN checks billing only before opening the session, while later NEG-MSG requests call reconcile without checking the paid period.
The ledger PR introduced the peering_payments table and the payments-service
settlement path, but the concrete repository implementation and factory wiring
were only added in the delivery PR. This meant PR1 could not actually settle a
peering invoice in production.
