`cargo bench -p homecore --bench state_machine` covers:
- set/first_write — cold-path insert + alloc + broadcast
- set/warm_write_state_change — same-entity update fires broadcast
- set/noop_suppressed — same state+attrs, no broadcast (HA semantic)
- get/hit + get/miss — zero-copy Arc<State> read paths
- all_snapshot/{10,100,1000} — Vec<Arc<State>> snapshot for REST
- all_by_domain_light_20_of_100 — domain prefix filter
- broadcast_fan_out/{1,4,16,64} — 1 sender + N subscribers, async,
measures end-to-end deliver-and-recv latency
The broadcast fan-out is the most load-bearing measurement for
HOMECORE — every integration, the recorder, the automation engine,
and every WS subscriber holds a receiver, so the per-subscriber
delivery cost determines how many add-ons the runtime can host.
criterion 0.5 with sample_size=20 (fast tick, the fast-path benches
run in nanoseconds and don't need 100 samples).

# HOMECORE — Rust state machine, event bus, service registry, entity registry.
|
|
# Implements ADR-127 (HOMECORE-CORE), the foundation of the HOMECORE Home
|
|
# Assistant port (ADR-126 master + ADR-128/129/130/131/132/133/134 sub-ADRs).
|
|
#
|
|
# P1 scaffold (this commit): public types + DashMap-backed state machine +
|
|
# Tokio broadcast event bus + minimal entity registry. Persistence and the
|
|
# full HA-compat serde schema land in P2.
