ORCA_PTY_BENCH_RUNS must be positive, received ${RUNS}
Error message
ORCA_PTY_BENCH_RUNS must be positive, received ${RUNS} What it means
Thrown by config/scripts/pty-batch-flush-benchmark.mjs when ORCA_PTY_BENCH_RUNS fails `!Number.isInteger(RUNS) || RUNS <= 0`. RUNS (default 30) is the number of measurement iterations the benchmark averages over; a non-positive value would make the timing loop produce no samples. Parsed at module load from the env, so the guard at line 26-27 fires immediately on bad input.

Solutions
- Set ORCA_PTY_BENCH_RUNS to a positive integer; for quick smoke runs use a small value like 3.
- Unset it to accept the default of 30.
- Validate in your wrapper that the value parses to a positive integer before invoking.
Example fix
// before ORCA_PTY_BENCH_RUNS=0 node config/scripts/pty-batch-flush-benchmark.mjs // after ORCA_PTY_BENCH_RUNS=3 node config/scripts/pty-batch-flush-benchmark.mjs
Defensive patterns
Strategy: validation
Validate before calling
const raw = process.env.ORCA_PTY_BENCH_RUNS
if (raw !== undefined && (!Number.isInteger(Number(raw)) || Number(raw) <= 0)) {
throw new Error(`ORCA_PTY_BENCH_RUNS='${raw}' must be a positive integer`)
} Type guard
function isPositiveInt(value) {
const n = Number(value)
return Number.isInteger(n) && n > 0
} Prevention
- For smoke runs use a small positive integer (e.g. 3) instead of 0.
- Keep RUNS >= 10 for stable averages; smaller values increase noise.
- Validate benchmark env vars in one shared preflight helper.
When it happens
Trigger: Run the benchmark with ORCA_PTY_BENCH_RUNS set to `0`, `-5`, an empty string, or a non-numeric token. parseInt at line 7 yields NaN for non-numeric input and the guard at line 26 throws.
Common situations: A developer sets RUNS=0 intending to 'dry-run' the benchmark (there is no dry-run mode), or a smoke-test wrapper sets RUNS to an empty value. Setting RUNS to a float like `1.5` actually passes (parseInt floors to 1), but `1.5px` style garbage fails.
