3//! 2026-09-26: The serve keys `met serve --hermetic` closes, as one table that the
4//! bench and server crates both read.

6//! Owner: bench gate.
7//! Invariants: none beyond the types.

9//! `metrale-server`'s `cli::hermetic` re-exports `CLOSED_KEYS` and expands a requested
10//! `hermetic=true` into these keys. `gate::bench` refuses a BENCH.toml entry that pins
11//! `hermetic=true` without them, because `scoring::check_record` also fails a record
12//! whose serve overrides hold a key the baseline does not pin.
