//! sibling helper records why: two separate per-module mutexes serialise
//! nothing against each other, and that produced a CI-only flake. The pair that
//! motivated this one is `meta::tests` (which renders a flake from
//! `HYPERHIVE_OTEL_*`) and `stats::otel_metrics::tests` (which asserts which
//! variable enables the exporter) — different modules, same variable, same
//! `HYPERHIVE_OTEL_EXTRA_RESOURCE_ATTRIBUTES`) and `stats::otel_metrics::tests` (which asserts which
//! variable enables the exporter) — different modules, same process env, same
//! binary.
//!
//! ⚠️ **A green local run is weak evidence for this class.** An agent container
//! has the hyperhive variables ambient-set, so a losing race still finds a
//! plausible value; the nix sandbox strips them, so there the race can delete a
//! variable out from under another thread. Reproduce the sandbox shape with
//! `env -u HYPERHIVE_OTEL_ENDPOINT cargo test -p hive-c0re`.
//! `env -u OTEL_EXPORTER_OTLP_ENDPOINT cargo test -p hive-c0re`.
