When credits land on a managed wallet, immediately fund that account's draining deployments instead of waiting up to an hour for the top-up cron. A manually paying user whose deployment is about to drain no longer risks it closing minutes after they paid to keep it alive. RefillService.topUpWallet publishes a FundDrainingDeploymentsCommand once credits land; a background handler reuses the cron's per-owner funding path (auto-top-up gate, partial-balance clamp, wallet-reload follow-up). Publishing goes through DomainEventsService, which swallows enqueue errors, so funding can never affect payment processing, and the hourly cron remains the safety net.

📝 WalkthroughWalkthroughThe change adds wallet-specific draining deployment funding jobs. Wallet top-ups return wallet identifiers, settlement publishes funding commands after commit, deployment services fund draining deployments with fresh balances, and the application registers the job handler.

Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The change funds draining deployments immediately after credits arrive. It is mergeable with owner awareness of a bounded duplicate-deposit race during overlapping jobs and a webhook test fixture that should mirror production wallet initialization. ✨ Finishing Touches📝 Generate docstrings

…ommits The FundDrainingDeploymentsCommand was published from RefillService.topUpWallet, which runs inside the Stripe settle @WithTransaction. The enqueue joins that DB transaction, so a transient failure aborts it; because authorizeSpending already ran on-chain and the rollback undoes the succeeded-status write, the retried webhook reads the inflated grant and credits the wallet twice. Move the publish to StripeTransactionService, after settleSucceededTransaction commits, mirroring the existing FirstPurchaseBonusGranted pattern. topUpWallet now returns the credited wallet so the post-commit caller can fund its draining deployments. A failed enqueue can no longer affect payment settlement, and the hourly cron stays the fallback.
…policy The FundDrainingDeploymentsCommand carried a per-wallet singletonKey, but pg-boss v12 ignores singletonKey on a standard-policy queue, so two top-ups for the same wallet could enqueue jobs that fund its draining deployments concurrently. Declare the singleton policy on the handler so the key is enforced: at most one funding job is active per wallet at a time, while different wallets still run in parallel up to the handler concurrency. The queue is created with this policy on first deploy (it is new in this PR), so no migration is needed. Overlap with the hourly cron pass and deposit-level idempotency remain tracked as a separate follow-up.

Why
Fixes CON-761
When a wallet has no credits, the hourly top-up pass skips its draining deployments. If the user then buys credits, nothing funds those deployments until the next hourly pass, so a deployment with under an hour of runway can be closed by the provider minutes after the user paid to keep it alive. Auto-reload users rarely reach this state; manually-paying users are the exposed group.
What
When credits land on a managed wallet (card purchase, auto-reload charge, admin manual credit, or coupon), the webhook settlement publishes a
FundDrainingDeploymentsCommandonce the crediting transaction commits. A background handler funds that account's draining deployments right away, reusing the per-owner path the hourly cron already runs. This is the same event-driven shape as CON-735 (fund on lease start).StripeTransactionService.#settleFromWebhookafter the crediting@WithTransactioncommits (mirroring the after-commitFirstPurchaseBonusGrantedpublish);RefillService.topUpWalletreturns the credited wallet instead of publishing. Publishing inside that transaction let a failed enqueue abort payment settlement and double-credit on the Stripe webhook retry, so it now runs post-commit. Enqueue errors are still swallowed and the hourly cron stays the safety net.TopUpManagedDeploymentsService.topUpDrainingDeploymentsForOwnerfunds one owner's draining deployments. The cron loop body is extracted into a shared private method so both paths behave identically (auto-top-up gate, partial-balance clamp, wallet-reload follow-up).DrainingDeploymentService.findDrainingDeploymentsForOwnerreturns a single owner's active draining deployments using the same look-ahead window and closed-marking as the cron sweep.CachedBalanceService.getFreshreads a fresh balance for the immediate path. The existinggetmemoizes per address for the process lifetime, which suits the short-lived cron CLI but would serve stale balances to the long-running background worker across successive credit landings.Acceptance criteria are covered by the reused logic: auto-top-up-disabled deployments are excluded by the existing SQL gate, partial coverage falls out of
reserveSufficientAmount, and trials keep the cron's existing clamped behavior (a purchase ends the trial anyway).No new env vars, migrations, or breaking contract changes.
Tests
Full
apps/apiunit suite passes. New coverage: the post-commit funding publish and its non-publish on an idempotent replay (stripe-transaction integration), the handler'ssingletonpolicy, handler delegation and retry, the per-owner draining query (active, closed-marking, empty), the immediate funding path (single tx, fresh balance, no-op when nothing drains), andgetFresh.Follow-ups
Refs CON-837. Same-wallet immediate funding is now serialized by the handler's
singletonqueue policy, so two top-ups for one wallet cannot fund it concurrently. The rest stays deferred: a bounded duplicate-deposit race when immediate funding overlaps the hourly cron (which does not go through the queue) or when a job retries after its deposit already landed on-chain, plus concurrency-safe instrumentation for the immediate path. These only over-fund the user's own escrow from their own authorized limit, and self-correct when the deployment closes.Summary by CodeRabbit
