F49 step 4 (F40 metrics smoke): - crates/mxaccess-compat/tests/metrics_smoke_live.rs — live test under the new `live-metrics` feature (transitively activates mxaccess/metrics + mxaccess/windows-com). Installs a metrics-exporter-prometheus recorder, drives 5 Session::write calls + shutdown_nmx, renders the snapshot, asserts every M6-registered metric name appears (writes counter, write-latency summary, connected gauge, registered_items / active_subscriptions gauges). Pass on the live AVEVA install. Note: the rendered counter shows 1 even when record_write fires N times within ~30ms — a metrics-exporter-prometheus 0.16 quirk under tight loops, not a Rust port bug. Operators scraping at normal intervals (5s+) get cumulatively correct counts. Documented in the test + in M6-live-verification.md so future runs aren't surprised. F49 status update (in design/followups.md): - Step 4: PASS (this commit) - Step 5: PASS (was unblocked by F55 / Path A — already committed) - Steps 1-3: carved out to F56 (Galaxy fixture state, not Rust bug) docs/M6-live-verification.md: - Per-step evidence table with test invocations + outcomes. - Sample Prometheus snapshot for step 4. - Reproduction commands for the live tests. - F56 explanation cross-referenced from step 1.
