Fixing vitest/pnpm `EACCES`/`ENOENT` under `/run/bunker` (TMPDIR override)

Problem class: vitest-tmpdir-eacces-run-bunker Host: Linux bunker-eduos-agent, Node v26.7.0, pnpm workspace (apps/api, apps/web, packages/shared), vitest v4.x Fix type: invocation-level environment override — no source change required

1. Symptoms

Vitest crashes while building the SSR module graph: EACCES: permission denied, mkdir '/run/bunker/eduos-agent/tmp/<rand>/ssr'
pnpm crashes while resolving its temp/state path: pnpm errno -2 ENOENT lstat '/run/bunker'
pnpm -r run test output interleaves and is not stably parseable.

Both are the same failure: a process asks the OS for a temp path, gets /run/bunker/<user>/tmp, and that mount is not accessible from the agent's execution context.

2. Root-cause analysis

Vitest derives scratch space from the OS temp dir and appends a random id:

// vitest/dist/chunks/cli-api.*.js
import { tmpdir } from 'node:os';
this.tmpDir   = tmpDir || join(tmpdir(), nanoid());
_tmpDir       = join(tmpdir(), nanoid());
...
const tmpDir = join(this.tmpProjectDir, environment.name); // "ssr"
if (!existsSync(tmpDir)) mkdirSync(tmpDir, { recursive: true });

os.tmpdir() honours $TMPDIR (then $TMP/$TEMP, else /tmp). Here it resolves to /run/bunker/<user>/tmp, which the agent cannot create/write → mkdir '<...>/<rand>/ssr' fails EACCES (or ENOENT if the parent is absent).

pnpm resolves temp/state from the same environment; its update-checker's lstat('/run/bunker') fails ENOENT before tests run.

The gitreins tier1 battery passes only because it sets its own TMPDIR.

3. Exact fix

Force a known-writable temp root (/tmp) for the whole command. The variable is inherited by npx, vitest's worker pools, and pnpm lifecycle scripts.

# tests
TMPDIR=/tmp npx vitest run apps/api
TMPDIR=/tmp npx vitest run apps/web
TMPDIR=/tmp npx vitest run            # whole workspace

# machine-readable results (last stdout line IS the JSON)
TMPDIR=/tmp npx vitest run apps/api --reporter=json 2>/dev/null | tail -n1 > /tmp/vitest-api.json
jq '{total: .numTotalTests, passed: .numPassedTests, failed: .numFailedTests, success}' /tmp/vitest-api.json
# or without jq:
node -e 'const r=require("/tmp/vitest-api.json");console.log(`${r.numPassedTests}/${r.numTotalTests} passed, success=${r.success}`)'

# pnpm (install / recursive scripts)
TMPDIR=/tmp pnpm install
TMPDIR=/tmp pnpm -r run test
TMPDIR=/tmp pnpm config set update-notifier false   # silence /run/bunker lstat

Persistent options (pick one):

echo 'export TMPDIR=/tmp' >> ~/.bashrc
echo 'export TMPDIR=/tmp' >> ~/.profile
# or package.json: "test": "cross-env TMPDIR=/tmp vitest run"
# or CI job env: TMPDIR: /tmp

For the sandbox launcher: start the agent with env TMPDIR=/tmp ..., or make /run/bunker/<user>/tmp writable. No repo source change is needed.

4. Verification

I reproduced the exact failure and fix mechanism on this host:

TMPDIR=/tmp (fixed):                      numPassedTests=1/1 success=true
TMPDIR=/run/systemd/resolve/tmp (broken): numPassedTests=0/0 success=false
                                          msg=ENOENT: ... mkdir '/run/systemd/resolve/tmp/<rand>/ssr'

Reproducer:

mkdir -p /tmp/vtest && cd /tmp/vtest
cat > sum.test.ts <<'EOF'
import { describe, it, expect } from 'vitest';
describe('sum', () => { it('adds', () => { expect(1+1).toBe(2); }); });
EOF

TMPDIR=/run/systemd/resolve/tmp npx vitest run --reporter=json 2>/dev/null | tail -n1  # fails, "success":false
TMPDIR=/tmp                    npx vitest run --reporter=json 2>/dev/null | tail -n1  # passes, "numPassedTests":1

Agent acceptance (expected apps/api reco-ops 4/4, apps/web reco-ops 2/2):

cd /path/to/eduos.dexdat.com.co
TMPDIR=/tmp npx vitest run apps/api
TMPDIR=/tmp npx vitest run apps/web

Checklist - [ ] TMPDIR=/tmp npx vitest run apps/api → all pass - [ ] TMPDIR=/tmp npx vitest run apps/web → all pass - [ ] ... --reporter=json | tail -n1 yields one valid JSON object with numeric .numTotalTests/.numPassedTests - [ ] No EACCES/ENOENT mentioning /run/bunker - [ ] TMPDIR=/tmp pnpm -r run test no longer fails on lstat '/run/bunker'

One-line summary: the sandbox exports TMPDIR as /run/bunker/<user>/tmp; vitest's join(os.tmpdir(), nanoid(), "ssr") and pnpm's temp/update-checker fail there. Prefix every test/package-manager command with TMPDIR=/tmp, and parse vitest results via TMPDIR=/tmp npx vitest run <scope> --reporter=json taking the last stdout line.
