The 50ms receive timeout was too short for relays that need time to
process a REQ query before responding. The pool's query_sync already
uses 1000ms. This matches that behavior to avoid premature timeouts.
Pass NOTICE and CLOSED message content to the callback so callers
can see what the relay actually said (e.g. auth-required, restricted,
rate-limited). Previously these messages were silently ignored.
The 8KB buffer was too small for large Nostr events (e.g. long-form
content in kind 30023). The pool's query_sync already uses 256KB.
This matches that size to avoid truncation when using the standalone
synchronous query functions for backfill.
Rescued from uncommitted work in sovereign_browser/nostr_core_lib:
- nostr_signer_derive_hmac(): deterministic MAC over caller data using the
signer's secp256k1 private key. Local backend computes HMAC-SHA256 directly;
remote nsigner backend calls the 'derive' verb (algorithm:'secp256k1').
- nsigner_transport_list_serial(): enumerate /dev/ttyUSB* (FTDI/CH340/CP210x/
PL2303 USB-serial adapters) in addition to /dev/ttyACM* CDC-ACM devices.
- tests/nsigner_client_test.c: local derive_hmac reference-match test.
