// The strip-and-retry only ever yields a sound label for Sources:
// `process.env.CMD` → strip → `process.env` makes sense because
// the receiver itself IS the source. Sinks and Sanitizers, by
// contrast, name the *operation* — `connection.query`, `eval`,
// `exec` — and stripping a trailing segment to match them is
// not semantically valid (e.g. `exec.start` should never be
// treated as a SHELL_ESCAPE sink because of bare `exec`). We
// accept any label on a full-text match (the behaviour callers
// already depend on for Source/Sink labels alike), but only
// accept Source labels after segment stripping.
