v0.1.54

What changed

• Added trace-to-skill session-audit [codex-home-or-sessions-dir] for local, read-only Codex history/session diagnostics.
• Reports rollout JSONL sizes, line counts, largest line sizes, parse errors, session index shortness, SQLite/global state file presence, and common session signals.
• Added schemas/session-audit-result.schema.json plus API exports for downstream tooling.
• Documented the command in README, use cases, discovery metadata, issue map, announcement copy, and OpenAI OSS evidence docs.

Why

This targets current Codex resume/Desktop history failures where codex resume <id> works but the interactive picker or Desktop thread list can freeze on large local session files. It lets users attach a privacy-preserving summary instead of posting private transcripts.

Verification

• npm run check
• git diff --check
• npm pack --dry-run --json
• CLI smoke test on a temporary session fixture: session-audit returned pass, 1 JSONL file, 1 rollout file
