codex-z 0.2.0

• Add Settings → Usage: compare Models on the work you actually did. Each row shows Sessions, Turns per Session, the share of Turns you stopped, and time, cost and tokens per Session, over 7 days, 30 days or all time. Columns are sortable. (#13)
• Record one line per completed Turn, for external Harnesses and native Codex, in ~/.codex-z/usage-ledger/turns.jsonl. The ledger keeps identifiers, the Model, timing, counters and the project path. It never stores prompts or Transcript text. (#13)
• Refresh the README with a product overview and screenshots. (#14)

Recording starts with this version; earlier Sessions are not included. Cost is each Harness's own estimate and appears only where the Harness reports one; native Codex reports tokens and time but no cost. The first Turn after importing or forking a Session has no cost or tokens.

Download the macOS or Windows installer for your architecture from the release assets.

npm publication for v0.2.0 is pending authentication. The Linux packages passed their build and installation smoke tests, but v0.2.0 is not available from npm yet.

Usage recording and the summary have automated test coverage. The Usage page has not been verified in a live Codex Desktop.
