Added remaining-todo document for Teensy 4.1 signer: captures v0.1.1-v0.1.5 fixes, current 20/24 suite score, and next steps for ml-dsa-65 sign hang (NTT correctness in matvec/scalar wrappers) and OTP decrypt mismatch

v0.1.5 - Fixed ml-dsa-65 SHAKE re-squeeze domain separation bug: poly_challenge, poly_eta, and poly_uniform_gamma1 re-absorbed the same seed on buffer exhaustion, producing identical output and potentially hanging the SampleInBall rejection loop; added a monotonic re-squeeze counter to the absorb buffer so each re-squeeze produces fresh bytes; note: ml-dsa-65 sign still hangs because the rejection loop never accepts a candidate — this is a separate NTT-correctness bug in the matvec/scalar multiplication wrappers that requires comparison against a PQClean reference implementation

v0.1.4 - Teensy 4.1 PQ stack fixes: moved ml-kem-768 NTT working polys (polyvec_matrix_pointwise 6656B, indcpa enc 9728B, indcpa dec 5120B, poly_mul_negacyclic 1024B) and ml-dsa-65 sign poly c (1024B) + SHAKE out buffers (2688B) from DTCM stack to DMAMEM (RAM2) static workspace; fixed ml-kem-768 keygen crash (verified on hardware); added ml-dsa-65 rejection-loop DMAMEM counter diagnostic; ml-dsa-65 sign no longer crashes but hangs due to pre-existing NTT correctness bug (rejection loop runs to exhaustion) — next milestone is to compare NTT output against host reference

v0.1.3 - Fixed Teensy 4.1 ed25519 sign/verify stack overflow: moved ed_add's 12 gf arrays (1536B), ed_frombytes' 9 gf arrays (1152B), sc_reduce/sc_muladd int64_t x[64] (512B), and ed25519_sign/verify SHA-512 ctx (328B) from DTCM stack to DMAMEM (RAM2) workspace; added persistent crash diagnostics (DMAMEM op marker + stack/heap measurement); full classical+Nostr suite now passes 16/16 in one uninterrupted boot (get_info, secp256k1/ed25519/x25519 pubkeys, schnorr+ecdsa sign/verify, ed25519 sign/verify, x25519 shared secret, derive, nostr pubkey/sign_event, nip04+nip44 round-trips)

v0.1.2 - Teensy 4.1 secp256k1 stack reductions + shared context: reduced WINDOW_A 5->4 (Strauss ecmult tables 8->4 entries, fixes schnorr verify stack overflow) and ECMULT_CONST_GROUP_SIZE 5->4 (ECDH tables 16->8, fixes nip04 crash); added secp256k1_get_shared_context() and reused it in dispatch.cpp ECDSA/schnorr helpers to eliminate per-request secp256k1_context_create/destroy heap fragmentation; reordered test_signer.py to test classical+nostr verbs before PQ verbs and added nostr_sign_event/nip04/nip44 round-trip tests

v0.1.1 - Fixed Teensy 4.1 NIP-04 crash and NIP-44 dispatch bug: reduced secp256k1 ECMULT_CONST_GROUP_SIZE 5->4 to halve ECDH stack usage (~3.5KB->~1.7KB) preventing DTCM stack overflow in secp256k1_ecmult_const during nip04/nip44 ECDH; fixed is_nip44 selector in dispatch.cpp (method[7] was always 'i', digit is at method[9]) so nostr_nip44_* verbs now reach the nip44 implementation instead of silently calling nip04; verified nip04+nip44 round-trip on hardware

server: ignore SIGPIPE so abrupt client disconnects don't kill the signer
...
The attended signer only handled SIGINT/SIGTERM. A client that disconnects
abruptly (e.g. nostr_core_lib's nsigner client reconnects per request and
closes the previous connection) could cause a write to the closed socket to
raise SIGPIPE, terminating the whole signer process after one request.
Ignore SIGPIPE process-wide so writes to closed sockets return EPIPE instead.
Verified end-to-end with nostr_core_lib note_poster --signer unix:nsigner-test
posting a kind-1 to relay.laantungir.net.
