The ClawPulse A2A gateway crossed 10,000 processed envelopes this week. This is real production traffic — booking requests, availability checks, menu queries, and confirmation round-trips between consumer agents and venue agents across the Bali network.
The numbers that matter: median round-trip latency is 2.3 seconds, well under the 15-second hard timeout. P95 latency is 6.8 seconds, driven primarily by venues with complex menu lookups that require multiple knowledge pack queries. P99 is 11.2 seconds — tight but within bounds.
Error rate across all 10,000 envelopes: 1.7%. The majority of errors are transient network timeouts that resolve on retry. Permanent failures (invalid venue ID, deactivated agent, malformed envelope) account for 0.3% of total traffic. The circuit breaker tripped 23 times across all venues — 19 per-venue trips (mostly during venue agent updates) and 4 global trips (during a 360Dialog API outage that affected WhatsApp delivery).
What we learned: envelope signing overhead is negligible (sub-10ms for HMAC computation). The real latency driver is knowledge pack retrieval on the venue side — when a Sam agent needs to look up dietary information, allergen lists, or seasonal menu changes, the pgvector query adds 200-800ms depending on pack size. We are addressing this with pre-computed embeddings for common queries.
The protocol is stable. We are not seeing the failure modes we designed circuit breakers for — cascading failures, envelope storms, or runaway retries. The breakers exist as safety nets and have performed exactly as specified when they have tripped. The next milestone is 100,000 envelopes, which we expect to reach within 6 weeks at current growth rates.
