Load protection (public read-only endpoint — protects relays + this box):
- Per-pubkey sliding-window throttle and in-flight cap via inbound middleware.
The transport can't return a JSON-RPC error, so over-budget callers are dropped
and time out (logged).
- Global semaphore caps concurrent upstream relay queries.
- Short-TTL cache keyed by filter set, so repeated identical queries (e.g. a
burst of get_community_stats) don't re-hit the relays.
- All tunable via CVM_RATE_* / CVM_MAX_* / CVM_QUERY_CACHE_MS (documented in
.env.example); maps pruned by a janitor.
CI:
- cvm-server/tsconfig.json type-checks the standalone server; new
typecheck:cvm / check:cvm scripts, with typecheck:cvm wired into npm test so
the server can't rot unnoticed (it was excluded from tsc + eslint).
