Codex Lifeboat 3.4.1 — faster backup and safer hand-offs

Nederlands

Codex Lifeboat 3.4.1 is a public testing release for carrying local Codex
projects, conversations, skills, and portable settings between Windows 10/11
computers. It is an independent community project, not an official OpenAI product.

Download

Most users should download only:

Codex-Lifeboat-Windows-x64-Portable.zip

Extract the ZIP completely and run Codex-Lifeboat.exe. Python, installation,
and administrator rights are not required. The standalone EXE and SHA256.txt
are also attached.

What changed

  • Faster backup creation: payload files are hashed once during creation instead
    of being read immediately for a duplicate full verification pass.
  • Verify backup remains the explicit independent SHA-256 reread of every file.
  • Large conversation histories with hundreds of unavailable historical attachment
    paths are analyzed without the previous severe slowdown.
  • The project-selection window opens maximized, shows more rows, and can be
    restored normally from the Windows taskbar.
  • Added a read-only diagnostics center with an anonymized support report.
  • Added a schema-aware portability audit for path-bearing Codex data.
  • Added read-only Git explanations for project conflicts without changing Git.
  • Critical JSON and checksum metadata now use durable atomic replacement.
  • Safe conversation continuation is automatic only when the destination history
    is proven to be an exact unchanged prefix of the longer backup conversation.

Safety and validation

  • Authentication and machine identity are never transferred.
  • Every completed package passes structural, SQLite, manifest, path, size, and
    lineage checks before receiving its final name.
  • Verify backup independently rereads and checks every payload SHA-256.
  • Source, packaged EXE, and freshly extracted ZIP pass 75/75 checks and 12/12
    automated Windows compatibility scenarios.
  • Backups are not encrypted and may contain source code, Git history, .env
    files, API keys, and conversation content. Keep backup media secure.
  • The EXE is not commercially code-signed, so Windows SmartScreen may warn.

Public testing status

This remains a pre-release while physical Windows 10, second-computer, USB-removal,
and complete A-to-B-to-A evidence is collected. Keep an independent copy of
irreplaceable data and never attach a real backup to a public issue.
