Answer 1

Root cause: vitest's run() helper does Number(err.code) when a spawned subprocess fails. When gitleaks is absent from $PATH, spawn('gitleaks') rejects with err.code === 'ENOENT', and Number('ENOENT') is NaN — producing the CI failure expected NaN to be 1. The real binary existed only at ~/go/bin (Go's default GOBIN), which is not on PATH.

Fix (durable, user-level, no sudo): install the real binary at ~/go/bin/gitleaks and make it reachable through ~/.local/bin, which is already on PATH (this session: $HOME/.local/bin is entry 2; the ~/.local/bin/env script also prepends it for future shells):

# 1. Place the real binary at the canonical GOBIN location
mkdir -p "$HOME/go/bin"
# e.g. via prebuilt static release or: go install github.com/gitleaks/gitleaks/v8@latest
curl -sL "https://github.com/gitleaks/gitleaks/releases/download/v8.30.1/gitleaks_8.30.1_linux_x64.tar.gz" \
  | tar -xz -C "$HOME/go/bin" gitleaks
chmod 0755 "$HOME/go/bin/gitleaks"

# 2. Expose it on PATH via ~/.local/bin (already on PATH — no profile edits needed)
ln -sfn "$HOME/go/bin/gitleaks" "$HOME/.local/bin/gitleaks"

# 3. Verify
command -v gitleaks   # -> ~/.local/bin/gitleaks
gitleaks version      # -> 8.30.1

No code change to the test suite is required — the run() helper's Number(err.code) path only ever sees a numeric exit code once the subprocess actually starts.

Evidence & signatures

Reproduced the exact CI failure with a helper that mirrors the test's `run()` (spawn with `shell: false`, map `err.code` via `Number()`):

| Scenario | Result |
|---|---|
| **Before fix** — PATH stripped of `~/.local/bin`/`~/go/bin`: `spawn gitleaks ENOENT`, `err.code="ENOENT"`, `Number(err.code) = NaN` | `ASSERT: FAIL — expected NaN to be 1` (verbatim CI005 failure) |
| **After fix** — normal PATH: `gitleaks version` → exit `0`, `Number(0)=0` | `ASSERT: PASS` |
| **Functional leak scan** — repo seeded with `AWS_KEY = "AKIA***"` (a real-format key; the canonical `AKIA…EXAMPLE` is allowlisted) | leak detected, exit `1` ✅ |
| **Clean scan** — benign repo | exit `0` ✅ |
| **Resolution chain** — `readlink -f ~/.local/bin/gitleaks` → `~/go/bin/gitleaks` (static ELF, `-x`), `command -v` resolves | ✅ |
| **Durability** — `PATH` contains `~/.local/bin` (1 entry confirmed); `~/.local/bin/env` prepends it for new shells; no `sudo`, user `kara` | ✅ |

**Edge cases covered:** ENOENT spawn error path (the NaN source); broken/self-referential symlink regression (the pre-existing `~/.local/bin/gitleaks` was a dangling link — verified it now resolves); `shell:false` PATH-based lookup (how `run()` invokes gitleaks); exit-code fidelity (0 clean / 1 leak) so `Number(code)` assertions get real values.

**Note on the guard-tests leg:** the harness's `test_command` greps for `Tests.*passed`, which also matches failure-summary lines (e.g. `Tests: 1 failed, ... passed`), so guard tests can pass vacuously even when tests fail. The harness code isn't present in this environment to patch; the durable fix is the on-PATH gitleaks above, which makes the real suite pass, not merely the grep.
