v4.1.0-rc5 — Public Beta
Pre-releaseNote
Historical prerelease. The current Stable release is v4.1.0.
The evidence below records RC5 at its original publication time; its tag and source remain unchanged.
RC5 Public Beta
RC5 adds:
- Natural-language Sol/Luna Status and Doctor diagnostics
- Degraded indicators
- Luna reference-cost Receipt metadata
- A safe diagnostic report
- Upgrade to Latest published-version discovery
- Installation dependency preflight
Installation requirements
The immutable RC5 setup contract requires all of the following before any Sol/Luna write:
- Codex CLI with a working
codex --version - Python 3.11+ with standard-library
tomllib - Git for immutable-source acquisition
- Read-only GitHub HTTPS access
- Native GPT-5.6 Luna capability at all five supported efforts
Codex Desktop alone does not satisfy the contract. Desktop-only installation is not supported in RC5.
Reference-cost boundary
Luna reference-cost is a same-batch ModelDial configuration comparison. It is not actual token usage, actual bill savings, subscription quota savings, or whole-task savings.
Validation boundary
Repository validation and exact-SHA CI passed on Windows, Ubuntu, and macOS. The documented-environment RC5 O1–O10 record remains bounded evidence.
Final re-certification not obtained due to Codex rollout-evidence compatibility.
No confirmed product-runtime regression.
