// decide whether the fixture's own `projector.finalize(...)` reached
// disk — if it did, the reporter is a no-op; if it didn't, it
// appends a synthetic `test-result` to terminate the file.

// Torn-write tolerance: a crash mid-`fs.writeSync` can leave a
// partial JSON object on the last line. `JSON.parse` failures are
// treated as "not terminated" — the reporter will then append its
// own terminator, and consumers who encounter the torn line follow
// the schema rule of discarding any trailing non-parseable line.
