The refinement sylpheed-port earned by sweeping their own instruction surface and
finding all of it loud: a wrong path errors out and announces itself, while an
inert environment variable returns a clean, wrong result. Only the silent kind
manufactures evidence.
Records that the silent surface is ENUMERABLE and therefore sweepable rather than
sampleable -- every env var the docs name, checked against the code -- with the
result of doing it, and the proxy warning that absent-from-code also flags
container paths the brief sets and no code reads.
This entry failed to apply in the previous commit (an exact-match assertion on
surrounding text) while the two document fixes it describes did land. Committed
separately rather than amended.
