Feature request: searchable local transcript history across sessions

What feature would you like to see?

Hi team! I built a small local workflow for searching Codex session records, and it turned out to be super useful in real multi-thread development.

I'd love to see this as a native Codex feature: searchable local transcript history across one or many sessions, focused on precise retrieval rather than just general recall.

Useful capabilities:

• search a single session or many sessions
• sort hits by time
• show nearby context around each hit
• filter out bootstrap noise and keep real message history
• preserve important evidence such as tool calls, shell commands, and code patch snippets

This is especially helpful when multiple Codex threads are working in parallel and the user or another thread needs to find the exact prior discussion, command, or patch instead of re-discovering it.

Additional information

I noticed a few related history/session issues, but this request is specifically about precise local transcript retrieval across sessions so parallel work can coordinate better and reuse exact prior work.

A lightweight CLI or built-in search panel would already be great. Happy to share the small reference workflow if useful.
