step 16: calling local:qwen3.8:27b
claim (unverified): Done. Fixed in `lib/argument.js`:

- **Defect:** `Argument._collectValue` had an inverted condition — `if (previous !== this.defaultValue || !Array.isArray(previous)) return[value]`. For a variadic argument, `command.js` reduces the slice of args starting from `declaredArg.defaultValue`, so the first value started fresh, and every subsequent value found `previous !== defaultValue` and started a *new* single-element array, discarding everything before it. That's why `['one', 'two']` came out as `['two']`.
- **Fix:** inverts the check to `if (previous === this.defaultValue || !Array.isArray(previous))`, matching `Option._collectValue`, so subsequent values append to the accumulated array.

`npm run --silent test` now passes: 1373 tests, 1372 pass, 0 fail, 1 pre-existing skip — verified against the shell evidence record. No tests were touched.

step 8: calling local:qwen3.8:27b
claim (unverified): Done.

- **Defect found and fixed** in `lib/argument.js`: in `Argument._collectValue`, the seeded commit had inverted the comparison — `if (previous !== this.defaultValue || !Array.isArray(previous))` — so an argument with an array default value started a fresh`[value]` instead of appending, breaking the "specified value is used instead of default (not appended)" behavior. Fixed to `if (previous === this.defaultValue || !Array.isArray(previous))`, restoring the original semantics.
- **Tests untouched**: `npm run --silent test` passes — 1373 tests, 1372 pass, 0 fail, 1 pre-existing skip (exit code 0, verified against the shell evidence record).
- **File-set gate addressed**: `lib/argument.js` is now declared in the file set, and it is the only changed file, so the gate's set-membership check is satisfied.

- **Cause of the gate failure:** in attempt 1, `lib/argument.js` was edited before any declaration, so the file-set gate rejected the change.
- **Fix:** recorded an `amend_file_set` amendment widening the declared set to include `lib/argument.js`, putting the widening in front of a reviewer as the gate requires. No test or assertion was touched.
- **Verification:** `npm run --silent test` exits 0 — 1373 tests, 0 failures, 1372 pass, 1 skipped — and the harness VERIFIED the exit-code claim against the shell evidence record.
