[Bug]: Shop Paykit request never arrives after restore; Encrypted Link stuck in recovery_required #1402

What happened?

Pubky Shop canary #2 on restored identity The Piotr (pubkyu5r19jcb1xfoh9szp6w4jmsfsy1hbgjpysjw6h1eyqo66x7uxmfy, ~7k on-chain). Seller Pav C Tester (pubkyadjnbqbam6b6nkcjp8iarxorjmqycxo6cwfzxspeyxaqjxmnjdcy).

Checkout for listing order 9b3adc7f asked Pay exactly ₿1,026 (Items ₿1,000 · Payment code ₿26). Shop showed “Delivered to your wallet. Open Bitkit to pay.”

After restore, Pav was not in contacts. Payment never arrived. After adding the contact (06:53:56 UTC), payment still never arrived. Logs then loop on Encrypted Link failure for that counterparty:

Failed to queue private Paykit endpoints for 'pubkyad…xmnjdcy' during 'foreground':
recovery required: Encrypted Link recovery is required for counterparty adjnbqbam6b6nkcjp8iarxorjmqycxo6cwfzxspeyxaqjxmnjdcy

and repeated:

Failed to advance private Paykit link … [Transport='code=transport_error, context=clear Encrypted Link outbox']

No Decoded incoming for 1026 in the session logs.

After the Shop payment window expired, a different request appeared in Bitkit: Sept 28 ₿1,255 “Accepted” (first canary / insufficient-funds leftover), not 1026. Pay and Dismiss both toast “Payment request operation is already in progress” (PaykitPaymentRequestError.OperationInProgress).

Related / prior: closed #1348 (same class, closed after retry fix), open iOS twin #776, session recovery work #1093. Marketplace thread: BitcoinErrorLog/pubky-marketplace#54.

Expected behavior

1. After adding the seller as a contact (or if checkout can target a non-contact), Encrypted Link recovers or surfaces a clear recovery UI — not a silent outbox-clear loop.
2. New Shop payment request (1026) is decoded and shown as payable while the window is open.
3. Stale Accepted requests after a failed send are dismissible / payable again, or no longer show Pay/Dismiss that only toast OperationInProgress.
4. Shop “Delivered to your wallet” should only appear when the wallet actually accepted the request (wallet-side; Shop may need an ack — called out on fix: add vertical scroll #54).

Steps to Reproduce

1. Restore The Piotr seed on mainnet Bitkit (identity that previously failed a Pav Shop pay for insufficient funds / stuck PR).
2. Confirm Pav C Tester is not in contacts.
3. Open listing, checkout for ~1000 sats → order with payment code (here 9b3adc7f / total 1026).
4. Observe Shop “Delivered…” while Bitkit never shows the new request.
5. Add Pav as contact; wait / foreground app — link stays recovery_required.
6. Let Shop window expire.
7. Open the old Sept 28 1255 “Accepted” request → tap Pay or Dismiss → toast “Payment already in progress” / “Payment request operation is already in progress”.

Workaround that previously worked for #1348: fresh Bitkit profile with seller already a contact — not retested here.

Reproducibility

Often (>50%) — reproduced on this restored identity; fresh-wallet workaround previously avoided it.

Additional context

• Restored wallet / poisoned private link to seller after earlier failed Shop canary.
• On-chain Paykit (private contact-gated); no Lightning channel involved for this pay.
• Mainnet / shop.pubky.app.
• Listing: https://shop.pubky.app/marketplace/listing/adjnbqbam6b6nkcjp8iarxorjmqycxo6cwfzxspeyxaqjxmnjdcy/3556805865a5490cb74f99ab95f43555
• Order ID 9b3adc7f; expected amount 1026; stale UI amount 1255.
