archy-x250-pa3's data volume filled to 100% (cuprate at 125G, since
removed) while a client had the ecash receive tab open. save_state's
write landed mid-truncate, leaving wallet/minibits.json at 0 bytes.
load_state then hard-failed every wallet.ecash-lnaddress call with
"EOF while parsing a value", surfaced in the UI as "Lightning address
unavailable" — permanently, since nothing ever cleared the bad file.
Registration is idempotent per pubkey (re-registering returns the same
lud16 Minibits already assigned), so there's no reason a corrupt local
mirror of that state should be fatal. load_state now treats an empty
or unparseable state file the same as a missing one — re-register and
recover the same address — instead of erroring. Manually cleared the
stuck file on archy-x250-pa3 as an immediate fix; this closes the gap
so it self-heals next time.

A Minibits /claim response consumes the payment server-side the instant
it's returned — it can never be re-fetched. claim_and_redeem previously
decrypted/redeemed each claim inline and just warn!-logged any failure,
so a mint-unreachable blip, a stale cached server key, or an operator
who'd edited their accepted-mints list to drop the default mint (via
streaming.configure-mints) could make a real payment vanish with
nothing but a log line to show for it — claimed_count/received_sats
still came back as a clean 0, identical to "nothing arrived."
Now: every fetched claim is persisted to MinibitsState.pending_claims
before decrypt/redeem is attempted, survives failures across polls
instead of being dropped, and claim_and_redeem no longer bails out on a
fetch error without first retrying whatever was already pending.
ensure_mint_accepted self-heals the accepted-mints allow-list so the
Minibits mint (the address is inherently backed by it) can't be
excluded out from under a claim. ClaimOutcome gains failed_count,
threaded through wallet.ecash-lnaddress-claim and shown in
ReceiveBitcoinModal so a stuck claim is visible instead of silent.
Also fixes the server_nostur_pubkey field-name typo (no live state to
migrate — this feature hasn't shipped yet).

The wallet used Minibits only as a Cashu mint, so the node could hold and
swap ecash there but had no addressable name at it. This derives a LUD-16
Lightning address (name@minibits.cash) from the node's own ecash wallet and
surfaces it in the ecash Receive tab above the existing paste-token box.
Identity reuses the NUT-13 ecash phrase, so there is no second secret:
- seedHash = sha256(mnemonic.to_seed("")) — the exact hash the Minibits app
stores, so restoring the same phrase recovers the same address both ways;
- Nostr keys via NIP-06 at m/44'/1237'/0'/0/0 (nostr-sdk Keys::from_mnemonic,
pinned by a unit test against the NIP-06 vector so a bump cannot silently
move the derivation and orphan the profile).
Backend (wallet/minibits.rs) implements the verified live /v3 flow: NIP-42
challenge/verify -> JWT, idempotent /profile registration with collision
retry, and /claim polling that NIP-04-decrypts each token (service pubkey read
from the address's own LUD-16 metadata, constant fallback) and redeems it
through ecash::receive_token. Mainnet-only; state cached 0600 in
wallet/minibits.json.
New RPC: wallet.ecash-lnaddress (register-or-read, idempotent) and
wallet.ecash-lnaddress-claim (sweep Lightning payments into ecash). The modal
fetches the address on tab open, renders QR + copy, and sweeps claims while
open; a registration failure is non-fatal so paste-token still works.
Verified end-to-end against production: registered a disposable
@minibits.cash address, confirmed it resolves via /.well-known/lnurlp, and the
claim poll returns cleanly.
