Three follow-ups from @miguel-heygen's review: 1. HERMES_QUIET — switch to existence check. `env["HERMES_QUIET"] === "1"` was brittle vs. future Hermes changes (e.g. if cli.py ever sets it to "true"). The var name itself is specific enough that existence is the right signal. 2. CI_PROVIDERS — convert to a discriminated union. `mode: "truthy" | "presence"` is stricter than the previous pair of optional boolean flags (which allowed entries with neither set). 3. Sandbox detection tests — add coverage. - Docker positive: /.dockerenv present → docker. - Negative case: plain Linux laptop with no markers → null. Together with the gVisor 4.4.0 fix in the previous commit, that addresses all three actionable callouts (the discriminated-union nit was non-blocking but worth doing while in the file).
