${name} must be a positive integer, received ${value}

Error message

${name} must be a positive integer, received ${value}

What it means

Thrown by the owner-settings selector benchmark when one of ORCA_OWNER_SETTINGS_BENCH_ROWS, BENCH_WRITES, or BENCH_WARMUP is set to a non-positive or non-integer value. The benchmark allocates fixture arrays sized by these, so zero/negative would produce degenerate arrays and NaN would corrupt timing.

Solutions

1. Omit all three env vars to use the defaults (ROWS=43, WRITES=2000, WARMUP=200).
2. Set each to a positive integer, e.g. ORCA_OWNER_SETTINGS_BENCH_WRITES=5000.

Example fix

// before
ORCA_OWNER_SETTINGS_BENCH_WRITES=0 node config/scripts/repo-owner-settings-selector-benchmark.mjs
// after
ORCA_OWNER_SETTINGS_BENCH_WRITES=5000 node config/scripts/repo-owner-settings-selector-benchmark.mjs

function readPositiveInt(name, fallback) {
  const value = Number.parseInt(process.env[name] ?? String(fallback), 10)
  if (!Number.isInteger(value) || value <= 0) {
    throw new Error(`${name} must be a positive integer, received ${value}`)
  }
  return value
}

function isPositiveInt(value) {
  return Number.isInteger(value) && value > 0
}

When it happens

Trigger: Setting any of the three env vars to 0, a negative number, or a non-numeric string. Number.parseInt('abc', 10) yields NaN, and Number.isInteger(NaN) is false.

Common situations: A developer sets WRITES=0 to run a quick test, or passes a decimal like 2000.5 (parseInt truncates but the check still passes since 2000 is an integer — however a purely non-numeric string fails).
