test(v2): wire bitspire's NIP-44 v2 cross-test fixture from coord log (#29 v1)
Bitspire posted the sample event at ~/dev/coordination/log.md
2026-05-30T13:15Z — encrypted via @bitSpire/nostr-client's
encryptContentV2 + createSignedEvent (the same production code path
the ATM bootstrap publish uses), round-tripped on bitspire side
before posting.
Replaces the @pytest.mark.skip stub from commit da07bae with three
real cross-impl byte-compat assertions in TestBitspireCrossTest:
1. test_decrypts_bitspire_sample_event — the load-bearing one. Our
nip44.decrypt_from recovers the expected
{"denominations": {"20": ..., "50": ...}} plaintext from the
fixture's ciphertext. Confirms our hand-rolled NIP-44 v2 produces
wire output that nostr-tools' impl reads, and vice versa.
2. test_signature_verifies_via_lnbits_helper — lnbits.utils.nostr.
verify_event returns True for the fixture's (id, pubkey, sig).
Confirms both sides hash the event id the same way + Schnorr-
verify under the same x-only public-key convention. The consumer
path runs verify_event before NIP-44 decrypt, so this is the
other half of the sig-algorithm agreement check.
3. test_encrypt_round_trip_via_our_impl_decrypts_with_their_keys —
encrypts the expected plaintext using OUR encrypt_for with the
fixture's ATM keypair as sender + operator pubkey as recipient;
decrypts back with OUR decrypt_from; asserts the recovered
plaintext matches. Locks the encrypt direction too. Asserts the
re-encrypted ciphertext differs from the fixture's (NIP-44 v2
nonces are random — byte-equality would be a CSPRNG regression).
If any of these ever fail, the spec ambiguity surfaces before either
side ships — exactly what the cross-test is for.
Same trap I made writing 16:35Z (didn't re-tail before writing, missed
bitspire's 13:15Z fixture post between my 15:55Z ask and the 16:35Z
ack) that bitspire owned at 07:55Z and I'd written into my session
memory as a rule. Symmetric lesson — the trap fires for any session
that goes head-down on implementation work.
Total: 149 passed (146 + 3 new), 0 skipped (cross-test no longer
skipped), 1 pre-existing async-plugin failure unchanged.
