Conversation
Preparatory for running the pre-claim failure bookkeeping from a single place. becomes a thin wrapper over , which holds the current body unchanged: the bounded inline work (resolve the payout destination, connect to LND, persist the idempotency claim) and the spawn of the background dispatch task. The body now takes and clones it where the spawned task needs an owned copy, so the wrapper keeps the order available for what comes next; the three existing calls in the LNURL branches drop their now-redundant . No behavior change: the wrapper only forwards the result.
Only three of do_payment's pre-claim exits ran check_failure_retries_or_log; the rest — no buyer invoice, fee eating the whole amount, an unreadable buyer pubkey, LndConnector::new failing on its cert/macaroon read, an undecodable payout invoice, a DB error on the claim write — returned Err with no bookkeeping. Four of them exit through ?, which is why they were easy to miss when added. Such an order keeps failed_payment = false and has no payout marker, so find_failed_payment and find_inflight_payouts both skip it. The seller is already settled by then, so the trade sits in settled-hold-invoice forever: the buyer is never paid, never notified, never re-prompted, and nothing is logged — the callers discard the error. Recovery needs a manual DB write. Do the bookkeeping once in do_payment, over the result of dispatch_payout, and drop the three now-duplicate inline calls (keeping both would double-count payment_attempts). Every error exit is covered, including the ? ones and any added later — exact rather than approximate, since dispatch_payout is only reached once the order is validated. The two paths that deliberately return Ok are documented on the function.
The four do_payment tests reached their error exits and stopped there, so nothing pinned what the order looked like afterwards — which is where the bug lived. They now persist a settled-hold-invoice order and assert, through a shared helper, that the failure left it recoverable: failed_payment set, payment_attempts at 1, the buyer notified, and no payout marker left for a payment that was never sent. Together those are what make the order selectable by find_failed_payment, and their absence is what made it invisible to both recovery jobs. The LND case is the regression test proper: it exits through ?, the shape that was missed. The LNURL case pins payment_attempts at 1, so the bookkeeping moving into do_payment cannot start counting twice and silently halve the buyer's retry budget.
WalkthroughPayout dispatch now centralizes pre-claim failure bookkeeping. Retry state is persisted before buyer-key resolution and other early returns. Tests verify recovery state, notifications, attempt counts, and missing payout markers. ChangesPayout failure handling

and check_failure_retries_or_log so retry fields are persisted immediately after
count_failed_payment, before resolving the buyer public key. Only attempt buyer
notification when get_buyer_pubkey succeeds, while preserving failure logging
for malformed keys, and add a regression test verifying malformed buyer keys
still persist failed_payment and payment_attempts.

check_failure_retries resolved the buyer pubkey, and ran the three payload checks of the retries-exhausted branch, before writing failed_payment and payment_attempts. Any of those four early returns dropped the write. That reopens the hole this branch closes, for one input: an order whose buyer pubkey is absent or unparseable fails in dispatch_payout and fails again inside the bookkeeping, on the very same call — so the settled order ends up with neither the retry flag nor a payout marker, invisible to both recovery jobs. Reachable through admin_settle, which does not resolve the buyer key before settling (release_action does, at its line 235). Move the write to just after count_failed_payment. The flag is what keeps the order selectable by find_failed_payment, so it must not depend on anything downstream succeeding. Notifications keep their early returns and the caller still gets the Err; the buyer is now never told about a failure that was not stored.

Reviewed the current head d76df6db464332df0609debb08a8138cd6b0d5b0.
I re-read the PR discussion and the linked payout-recovery context, then checked the src/app/release.rs change against the failure/retry invariants from the previous payout work. The wrapper around dispatch_payout correctly centralizes pre-claim failure bookkeeping, and the moved persistence in check_failure_retries closes the missing-buyer-key/notification-failure gap without clobbering unrelated order fields. The tests cover the important regression cases: no invoice, zero buyer amount after fee, unusable buyer pubkey, LND setup failure, LNURL validation, and the dispatch-classification paths.

Follow-up to the buyer-payout work in #881, #883 and #893, covering the one
residual case surfaced:
Only three of
do_payment's pre-claim exits rancheck_failure_retries_or_log.The rest , no buyer invoice, fee eating the whole amount, an unreadable buyer
pubkey,
LndConnector::newfailing on its cert/macaroon read, an undecodablepayout invoice, a DB error on the claim write, returned
Errwith nobookkeeping. Four of them exit through
?, which is why they were easy to miss.An order that takes one of those exits keeps
failed_payment = falseand has nopayout marker, so
find_failed_payment(needs the flag) andfind_inflight_payouts(needs the marker) both skip it. The seller is alreadysettled by then, so the trade sits in settled-hold-invoice forever: the buyer is
never paid, never notified, never re-prompted for an invoice. Nothing is logged
either — all three callers discard
do_payment's error. Recovery needs a manualDB write.
An unreachable LND is not a trigger:
connect()is lazy, so it fails after theclaim, where reconciliation already owns the outcome.
The fix
Do the bookkeeping once, in
do_payment, over the result ofdispatch_payout,instead of at each exit. Every error path is covered, including the
?ones andany added later — which is the point: the bug exists because the per-site
convention was forgettable, and it was forgotten twice.
dispatch_payoutis only reached once theorder has been validated, so each of its error exits means the buyer could not be
paid. Documented on the function, together with the two paths that deliberately
return
Ok(a lost claim CAS, and the post-claim work that runs in the spawnedtask and does its own bookkeeping).
Three commits: a no-behavior-change split, the fix itself (~15 lines), and tests.
Verification

than the current behavior.
payment_attempts == 1: moving the bookkeeping up cannotstart counting twice and silently halve the buyer's retry budget.
Verified on regtest (Polar, LND alice): with the daemon running, the cert file
it reads was moved aside, its long-lived client keeps working, only
do_payment's fresh connector fails. On release, the hold invoice settled andthe order was marked 70ms later (
has 1 failed payments retries), withfailed_payment = 1,payment_attempts = 1and no payout marker; the buyer gotpayment-failed. Restoring the cert, the retry job picked the order up on itsnext tick and paid it unattended,
success,purchase-completedandratewithin 40s, no intervention. On the old code that order would have stayed in
settled-hold-invoice with nothing logged.
