## Two CI failures on PR #778 fixed ### 1. Rust Workspace Tests (E0601: `main` not found in mqtt_publisher) Default `cargo build --workspace` compiles examples without forwarding `--features mqtt`. The example had a crate-level `#![cfg(feature = "mqtt")]` so the entire file evaporated, leaving zero `main`. Now provides a stub `main` when the feature is off (prints a hint and exits 2), and gates the real implementation behind `#[cfg(feature = "mqtt")]` per-item. Local verification: cargo check --no-default-features --examples → clean ### 2. mqtt-integration (mosquitto never became reachable) `eclipse-mosquitto:2.x` rejects anonymous connections by default and GH Actions `services:` containers don't easily support volume-mounting a custom config. Removed the service container and start mosquitto manually in a step with an inline `allow_anonymous true` listener on port 11883. Same wire shape, no auth (CI tests protocol behaviour, not security — production uses mTLS per ADR §3.9). ## Benchmark numbers captured (`docs/integrations/benchmarks.md`) Ran `cargo bench --features mqtt --bench mqtt_throughput` locally: | Hot path | Measured | Target | Better by | |---------------------------------------|----------|--------|-----------| | state::event_fall encode | 259 ns | <2 µs | 7.7× | | rate_limiter::allow_first | 49.7 ns | <100 ns| 2× | | rate_limiter::allow_within_gap | 62.1 ns | <100 ns| 1.6× | | privacy::decide_hr_strip | 0.24 ns | <50 ns | 208× | | privacy::decide_presence_keep | 0.24 ns | <50 ns | 208× | | semantic::bus_tick_all_10_primitives | 717 ns | <10 µs | 14× | At 1 Hz publish rate per node, the entire ADR-115 hot path costs ~1 µs per node per tick on commodity hardware. A Cognitum Seed hosting 100 nodes would burn 100 µs/sec — 0.01% load floor. Memory: ~30 KB total FSM state for 10 primitives × 100 nodes. The numbers exceed every target by ≥1.6×, several by 100×+. No need to optimise further for v0.7.0. Refs #776, PR #778. Co-Authored-By: claude-flow <ruv@ruv.net>
