pub const DOCUMENTED_ENVIRONMENT: &[&str];Expand description
Environment recognised by the CLI, as reported by robot schema.
It lives beside the catalogue rather than in lib.rs because it is part of the promised
agent-facing contract, and the frozen fixture pins it: adding a variable without documenting
it here fails the contract test.
The ONE list of user-facing environment levers. ftts doctor reports exactly this set,
and the frozen schema fixture pins it, so a lever added anywhere else without an entry
here fails the contract test — the split-brain where robot schema and doctor
disagreed (and neither mentioned the resident daemon’s levers) is what this fixes.
Development-only probes (FTTS_SPEC_PROBE, FTTS_ORACLE_FIXTURES, FTTS_RECEIPTS,
FTTS_TOKENIZER_REGEX, FTTS_LOAD_THREADS) are deliberately not part of the promise.
