🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Use a button for the raw JSON toggle.
The toggle is a div with only an onClick handler. It has no button role and no tabIndex, so keyboard and screen-reader users cannot open the raw JSON view. The file already has a Button component for this purpose.

Arkana review — PR #1090 What this doesTwo independent fixes shipped together:

2. setState({ status: 'has-remote', card: remote.card })
3. <div onClick={() => setShowRaw((show) => !show)} style={{ cursor: 'pointer' }}>Keyboard and assistive-technology users cannot reach this. Replace with 4. const match = cards.find((c) => c.pubkey === rendezvous.pubkey) ?? cards[0]If the relay returns cards but none match SummaryThe cache-bypass fix is correct and well-tested. The detail view is the right UX for surfacing stale-limits. Three issues need addressing before merge: the |

Follow-up review — ad39d03 (force-push rebase + 3 fixup commits since d01cd07)
Since the last pass: the PR was rebased and three new commits landed — 0afd36c (modal cleanup), 1d47ba2 (extract shared pool to solverCardRemote.ts), f3c7e3f (T[] lint fix) — plus a rebase onto main that picked up 46c16db (IndexedDBIntentRepository). 0 of 4 prior findings fixed; all four remain open.
Prior finding status
Finding 1 — src/lib/solverCardRemote.ts as never cast — Still open
The pool extraction (1d47ba2) landed the cast in the new file rather than fixing it:
// solverCardRemote.ts (current HEAD)
const cards = await fetcher.fetch(solvers as never, network)Still needs a proper structural type or local interface that satisfies TransportCardFetcher.fetch's input.
Finding 2 — src/screens/Settings/Solvers.tsx unvalidated remote card in state — Still open
The useRemoteCard hook still stores remote.card (type unknown) without running validateCard:
setState({ status: 'has-remote', card: remote.card })The modal cleanup (0afd36c) did not add validation. The crash path is still live: CardDetails casts to Card and feeds the result to MarketLines, which calls .map() on remoteCard?.markets. If a relay serves a card where markets is anything other than an array (e.g., a string, or an object), remoteCard?.markets ?? [] returns the non-array (it's truthy), and MarketLines throws TypeError: .map is not a function at render time. Run validateCard(remote.card) before the setState; on failure set status: 'error'.
Finding 3 — src/screens/Settings/Solvers.tsx non-interactive raw-JSON toggle — Still open
The <div onClick> is unchanged after the modal cleanup:
<div onClick={() => setShowRaw((show) => !show)} style={{ cursor: 'pointer' }}>Keyboard and assistive-technology users cannot activate it. Swap for the in-scope <Button> component, or at minimum add role="button", tabIndex={0}, and an onKeyDown handler.
Finding 4 — src/lib/solverCardRemote.ts pubkey fallback ?? cards[0] — Still open (nit)
const match = cards.find((c) => c.pubkey === rendezvous.pubkey) ?? cards[0]Returning null rather than an unmatched card is the safer choice, particularly as more solvers share relays. No change from last pass.
New in this diff
src/lib/solverCardRemote.ts — pool extraction (1d47ba2) — clean
Factoring sharedPool and sharedTransportCards() out of swapMarkets.ts into their own module is the right move. The module-level singleton is app-lifetime-scoped, nostr-tools' SimplePool handles reconnect internally, and the lent-pool pattern avoids the CLOSE/send race described in the comment. Architecture is sound.
src/wallet-service-worker.ts — IndexedDBIntentRepository (rebase from main/#1066) — no issue
The three added lines (IndexedDBIntentRepository import, construction, and intentRepository key in the MessageBus config) match 46c16db which was already merged to main. This is a rebase artifact, not a change introduced by this PR. Nothing to act on.
src/components/FlexRow.tsx wrap prop — clean
Additive; used correctly in BundledCardLine and CardLine for the button row.
Summary
The structural work (pool extraction, modal cleanup) is good. Findings 1, 2, and 3 from the first pass are must-fix before merge; finding 4 is a nit. The only unblocking change needed to avoid a user-visible crash is finding 2 — add validateCard on the relay-fetched payload before it enters state. Findings 1 and 3 are correctness/accessibility issues that should follow immediately after.

Follow-up review — c780d8a (pool unification + in-flight dedup + SDK upgrades since ad39d03)
Since the last pass: pool handling was refactored into sharedNostrPool() in nostr.ts, in-flight deduplication was added to fetchRemoteSolverCard, the useRemoteSolverCard hook was extracted to its own file, and @arkade-os/swap / @arkade-os/sdk / nostr-tools were upgraded. 1 of 4 prior findings fixed; 3 remain.
Prior finding status
Finding 1 — src/lib/solverCardRemote.ts:58 as never cast — Still open
Unchanged. The cast is now inside the inflight IIFE but the root cause (solvers array type not matching TransportCardFetcher.fetch's input) is unaddressed.
Finding 2 — src/hooks/useRemoteSolverCard.ts:29 unvalidated remote card — Still open
The hook was extracted from Solvers.tsx into src/hooks/useRemoteSolverCard.ts, which is a clean refactor, but the payload enters state without validation:
setState({ status: 'has-remote', card: remote.card })remote.card is unknown. CardDetails (Solvers.tsx:183) casts it to Card and feeds remoteCard?.markets straight to MarketLines.markets: Market[]. The only guard is typeof remote.card === 'object', which passes for { markets: "a string" }. MarketLines calls .map() on the guarded value — a non-array that is truthy bypasses the ?? [] and causes TypeError: .map is not a function at render. Run validateCard(remote.card) before the setState; on failure set status: 'error'. Must fix before merge.
Finding 3 — non-interactive raw-JSON toggle — Fixed (c0ac71e)
The <div onClick> was replaced with the <Button> component at Solvers.tsx:229-232, which renders <button type="button">. Keyboard and AT users can now activate it.
Finding 4 — src/lib/solverCardRemote.ts:62 pubkey fallback ?? cards[0] — Still open (nit)
Unchanged. Returning null instead of an unmatched card remains the safer choice when multiple solvers share relays.
New in this diff
Pool unification → nostr.ts:sharedNostrPool() — clean
Merging the solver-card pool into the app-wide sharedNostrPool() eliminates the second module-level SimplePool from solverCardRemote.ts. Backup (NostrStorage) and solver-card discovery now share one pool; their subscriptions are independent (different event kinds / filter sets), so there is no interference.
In-flight deduplication (inflight Map) — clean, well-tested
src/lib/solverCardRemote.ts:35–70: the module-level Map<string, Promise<RemoteSolverCard | null>> keyed on network + ':' + pubkey is initialised synchronously before the first await, cleaned up in finally (correct, no leak), and the promise is shared with all concurrent callers. The tests at solverCardRemote.test.ts:61–92 cover concurrent-share and post-settle re-read correctly.
useRemoteSolverCard hook extraction — clean refactor
src/hooks/useRemoteSolverCard.ts is a verbatim move from Solvers.tsx. No behavioural change.
nostr-tools pinned at 2.24.1 (removed ^) — good
Pinning a Nostr/crypto dependency removes the risk of a surprise minor-version upgrade pulling in changed event-signing behaviour. The bump from 2.17.2 → 2.24.1 is substantial; nothing in the diff suggests breakage, and the tests pass, but the changelog should be skimmed before merge to confirm no signing or relay-protocol changes affect backup or discovery.
SDK bumps (sdk@0.5.0-rc.25, swap@0.1.0-rc.28) — no visible breakage
Types compile, tests pass. No interface changes surface in this diff.
Summary
Finding 3 is fixed. Findings 1 and 2 are must-fix before merge; the remaining work is small. Finding 2 is the only user-visible crash path: add validateCard(remote.card) in useRemoteSolverCard.ts before setState and fall through to status: 'error' on failure. Finding 1 requires a proper input type to replace the as never cast.
Follow-up to the pinned-solver stale-limits report: a solver publishing with NOSTR_AD_PUBLISH=auto can change limits while the wallet keeps quoting the pinned copy, and the market watcher could additionally serve the pre-update snapshot for up to ~15 minutes via the shared market cache.
