…paid Phase 2 of wallet protection. Config drift (phase 1) trusts what BTCPay reports; this checks the invoices that were actually paid, so it holds even when BTCPay lies about its configuration. - Bolt11: bech32 + tagged-field parser with ECDSA public-key recovery on secp256k1 (paragonie/ecc, already a dependency). Verified against the BOLT #11 spec vectors and real mainnet invoices. - PayeeAttestationService: at every baseline a canary invoice (0.00000100 BTC, 1-minute expiry, metadata satflux_canary, archived right after reading) yields the signing node id -> wallet_connections .payee_pubkeys (source canary); when the canary cannot be read the first settled payment is trusted (first_payment). Every settled Lightning payment - hooked into SettlementLedgerService::syncInvoice, which already fetches the invoice payment methods from the webhook - is decoded and its payee must be on the list. A mismatch sets payee_mismatch_at once (conditional update), audits payee_mismatch and raises the merchant security message + e-mail and the admin alert naming the invoice and node. - Admin: incidents list includes payee mismatches with "accept node" (adds to the allow-list, audits payee_accepted) and "relearn node"; merchant card shows the incident; wallet-connections:learn-payees command runs daily for rows still without an allow-list. - InvoiceService::forgetInvoiceCache now also drops the payment-methods cache; a webhook-driven resync could otherwise read stale payments. - Docs (EN + SK), locales (5), tests: Bolt11Test (spec vectors), PayeeAttestationTest (canary, TOFU, mismatch once, reconnect, admin, command, merchant endpoint).

Inline comments:
In `@app/Services/BtcPay/InvoiceService.php`:
- Around line 27-28: Move the archiveInvoice method below listInvoices or
createInvoice so its docblock is associated with the correct method and no
longer inherits references to nonexistent filters, skip, or take parameters.
- Around line 30-42: Update the invoice deletion flow in InvoiceService to use
BtcPayClient::withUserKey() for the delete request instead of manually changing
and restoring the API key, preserving restoration even when the original key is
empty.
In `@app/Services/WalletSecurity/Bolt11.php`:
- Line 142: Update the pico multiplier in the amount conversion mapping used by
Bolt11 decoding so the p-unit divisor is 10^12 rather than 10^13. Preserve the
existing n-unit conversion and all other denomination mappings.
- Around line 94-99: Update the payee handling in the Bolt11 decoder around
recoverPubKey so a present n field is cryptographically validated against the
invoice signature and hash before being accepted; only recover the key when n is
absent, and reject or flag mismatches so attestBolt11 cannot consume an
unverified payee.
In `@docs/user/en/wallet-security-alerts.md`:
- Line 42: Qualify the unconditional payee-verification guarantee to state that
verification may be unavailable if PayeeAttestationService::attestInvoice fails
while SettlementLedgerService::syncInvoice continues settlement. Update the
corresponding English text at docs/user/en/wallet-security-alerts.md:42 and
Slovak text at docs/user/sk/wallet-security-alerts.md:42; no code change is
required.
- Line 42: Update syncInvoice so failures from
PayeeAttestationService::attestInvoice are retried or cause the flow to fail
closed before syncPaymentMethod records a settled payment; alternatively revise
the documentation to state that attestation failures are logged while settlement
continues.
- Line 44: Update the wallet-security guidance in both
docs/user/en/wallet-security-alerts.md:44-44 and
docs/user/sk/wallet-security-alerts.md:44-44 to state that only an admin can
accept or relearn a node after investigation. Remove the inaccurate support
confirmation workflow and keep the English and Slovak wording consistent.
In `@tests/Unit/Bolt11Test.php`:
- Around line 31-34: Update Bolt11::decode to verify the invoice signature
against the public key supplied by the n tag, rejecting any signer mismatch
before applying the payee allow-list check; preserve existing recovery behavior
when n is absent. Add a test fixture with a valid Bech32 checksum but a
mismatched signer, and assert that decoding rejects it.

- Bolt11: always recover the signer; an explicit `n` field is accepted only when it equals the recovered key, otherwise the invoice is rejected (a forged `n` can never become the attested payee). Test builds a signed invoice with a matching `n` and a forged one. - Bolt11: pico-BTC divisor is 10^12, not 10^13; verified with the spec's "amount in pico-BTC" example (967 878 534 msat). - InvoiceService::archiveInvoice moved below createInvoice (it had picked up an orphaned docblock) and uses BtcPayClient::withUserKey, which also restores the server key when the previous key was empty. - Docs (EN + SK): attestation failures are logged while the payment is still recorded; only an administrator can accept or relearn a node.
