S00-031 executor evidence

Agent: auto-ci-cd-d45ccd3ee7d6 (ci-cd), 2026-10-15. Awaiting independent QA. Input: coordinator-supplied host confirmation in previous S00-031 handoff, assigned card/packet and required reads. Output: verified bounded host-context diagnostic and docs/AUTOMATION.md instructions. Acceptance: valid host socket metadata; inner project write/read/remove succeeds; outside write denied; no additional model/storage execution.

Read master/AGENTS/README/common/ci-cd, all six startup docs, TESTING/storage/ADR registry, all five required blocker reports, existing handoff, S00-002 accepted ADR and executor/review evidence/handoff. resume/show/packet each exit 0; assignment already in_progress, no repeat claim. No exact product requirement applies to this engineering task.

Independent diagnostic

• Outer restricted-shell Python stat: exit 0, /tmp/codex-daemon-1000, directory=true, uid1000, mode000. Socket contents not read.
• Read and inspected coordinator probe /tmp/luma-filesystem-sandbox-probe.py before execution; synthetic data only, no subprocess/model/network inside script.
• Approved exec_command with sandbox_permissions=require_escalated ran the Python wrapper below from project root: exit 0. Host directory=true, uid1000, mode0700. Inner sandbox exit 0. JSON: {"project_write_read_remove":"passed","outside_project_write":"denied","denial_errno":30,"outside_probe_created":false,"uid":1000}. Timeout 20 seconds did not expire. No root/config/socket mutation. This outer execution allows the inner sandbox to initialize; the probe runs only inside that inner sandbox.
• codex --version: exit 0, codex-cli 0.159.0; warning that PATH aliases could not be created on read-only filesystem. It did not prevent version output or successful host diagnostic.

Exact host wrapper (requires approved outer host execution; do not run the probe directly on host):

import os, stat, subprocess
p = '/tmp/codex-daemon-1000'
s = os.stat(p)
print({'context':'host','path':p,'uid':s.st_uid,'mode':oct(stat.S_IMODE(s.st_mode)),'directory':stat.S_ISDIR(s.st_mode)}, flush=True)
assert s.st_uid == os.getuid() and stat.S_IMODE(s.st_mode) == 0o700 and stat.S_ISDIR(s.st_mode)
r = subprocess.run(['codex','-c','sandbox_mode="workspace-write"','-c','sandbox_workspace_write.network_access=true','sandbox','--','python3','/tmp/luma-filesystem-sandbox-probe.py'], timeout=20)
print({'sandbox_exit_code':r.returncode}, flush=True)
raise SystemExit(r.returncode)

Full inspected and executed temporary script, which QA can restore under /tmp if needed:

from pathlib import Path
import uuid,json,os,errno
root=Path('/home/tola/Documents/workspace_micran/swift/web-foundation')
inside=root/'state/runs'/('.sandbox-probe-'+uuid.uuid4().hex)
inside.write_text('synthetic probe\n');assert inside.read_text()=='synthetic probe\n';inside.unlink()
outside=Path('/home/tola')/('.luma-sandbox-denied-'+uuid.uuid4().hex)
try:
 with outside.open('x') as f:f.write('synthetic boundary test\n')
except OSError as e:
 assert e.errno in {errno.EROFS,errno.EACCES,errno.EPERM},e
 print(json.dumps({'project_write_read_remove':'passed','outside_project_write':'denied','denial_errno':e.errno,'outside_probe_created':False,'uid':os.getuid()}))
else:
 outside.unlink();raise SystemExit('Filesystem boundary failed: outside-project write succeeded')

No broader writable roots or unrestricted inner execution flags supplied. The installed Codex workspace-write defaults remain intact, including temporary storage. The negative probe is under /home/tola, outside project and temporary roots. No authentication/API/model call or storage task ran. One filesystem boundary is tested, not all sandbox capabilities.

Documentation and checks

Only source change: docs/AUTOMATION.md, host-specific diagnostic instructions and evidence link. Workflow evidence/handoff/message are metadata. Existing coordinator-supplied handoff is preserved below the executor handoff addition.

• python3 scripts/tasks.py validate: exit 0, 296 tasks, 22 stages, 221 requirements, 211 allocated Web requirements, revision98.
• git diff --check: exit 0 before final metadata.
• First documentation write attempt: shell exit1, unmatched backtick caused by an outer heredoc delimiter colliding with an embedded documentation delimiter; no file changed. Retried using a unique delimiter successfully.
• First make check: exit2, 72 tests ran, four prompt-budget errors for S21-006 claim/review after the long initial documentation draft. Replaced that draft with compact instructions and placed full reproduction here; no runner/test/plan change.

Official OpenAI security documentation opened on 2026-10-15: https://developers.openai.com/codex/security (redirects to https://learn.chatgpt.com/docs/security). General context only; host metadata and pass/fail above derive from actual execution, not documentation. No claim that this experiment accepts S00-030/028/storage or product readiness.

• Final make check > /tmp/luma-S00-031-check.log 2>&1: exit0, 72 tooling tests passed in 18.967s, including all fresh prompt budgets. Foundation checks only. Final git diff --check: exit0.
