* tests/integration/meta/env/test_dotenv_generator.py picks up a module-level `STATIC_READS` tuple on every dynamic handler module under utils/env/handlers/, in addition to PASSTHROUGH_STATIC_KEYS and GHA_STATIC_KEYS. So a handler that pulls its fallback from `ctx.static[KEY]` (e.g. infinito_outer_network_mtu) can declare the key it reads without flipping the drift detector. * utils/env/handlers/infinito_outer_network_mtu.py exports `STATIC_READS = (KEY,)` accordingly and marks the two live system reads (`/proc/net/route`, `/sys/class/net/<iface>/mtu`) with `# nocheck: cache-read` since the cached-read lint forbids uncached `Path.read_text` calls inside utils/. * utils/env/loader.py marks the `INFINITO_ENV_LOADED` sentinel with `# nocheck: env-loader-internal-guard` so the registry-drift lint does not treat the idempotency flag as a missing config key.
