Summary

Keep completed scan artifacts inside the validated scan output tree when a post-scan follow-up fails.

Changes

  • Snapshot sealed artifacts through checked file handles before starting the follow-up.
  • Capture the canonical scan-root identity before the follow-up and bind restoration to that identity.
  • Restore through descriptor-relative POSIX operations and held Windows handles so replacement roots, linked parents, and parent swaps cannot redirect a write.
  • Skip rewriting unchanged artifacts while preserving recovery for missing, damaged, unreadable, nested, and binary artifacts.
  • Treat restoration setup failures as warnings and return the completed scan without starting the follow-up.
  • Merge current main and remove unrelated credential-lock changes from this branch; that work remains in fix(runtime): use process-owned credential-home locks #613.

Testing

  • bun test --timeout 30000 tests-ts/api-post-scan.test.ts tests-ts/contract.test.ts: 56 passed
  • bun test --timeout 30000 tests-ts/api.test.ts: 118 passed, 2 platform skips
  • bun test --timeout 30000 tests-ts/api-credentials.test.ts: 5 passed
  • pnpm run types
  • pnpm run format
  • pnpm run build
  • uv run ruff check _bundled_plugin/scripts/finalize_scan_contract.py _bundled_plugin/scripts/windows_scan_local_files.py
  • pnpm pack --pack-destination ../../dist
  • pnpm run check:package ../../dist/openai-codex-security-0.1.16.tgz: installed-package smoke passed and 255 entries validated
  • git diff --check and git diff --cached --check

Native Windows execution remains covered by CI; I did not wait for CI before moving to the next PR.

Risk and rollout

This does not change the documented SDK surface, CLI, flags, environment variables, dependencies, or state format. Failed follow-ups may atomically replace damaged sealed artifacts, then the completed contract is revalidated. Unchanged artifacts keep their existing file identity and timestamps.

If the scan root or an artifact parent changes identity, restoration fails closed instead of writing through the replacement path. If restoration setup itself is unavailable, the follow-up is skipped and the completed scan is returned with a warning.

Public disclosure review

  • No customer, partner, prospect, or user identities, data, or identifying details are included.
  • No credentials, personal data, private source, scan findings, or nonpublic links or tickets are included.
  • I reviewed the branch name, title, description, commits, changes, comments, logs, screenshots, attachments, and links for public disclosure.

The second attestation remains unchecked because already-published history includes an author email, access-restricted report links, and public review discussion of the vulnerability. This update does not rewrite public history.

@codex review

Please review the current head e8fc845591364b41ac8da88462098e90852df680. This additive follow-up fixes transient Windows credential-lock reads and test cleanup. The artifact-restoration implementation is unchanged.
