   Would love to take this on...

   My understanding is that the Codex adapter should follow the adapters/ pattern from #22... a thin Python Codex-specific infrastructure? Rather than a separate host implementation under reference-implementations/agt. Also the related adapter work in #108

   Starting point would be the blocking PreToolUse path and get one complete slice

   Codex PreToolUse -> steps/toolCallRequest -> Guardian decision -> Codex allow/deny/modified input

   Would then add the emission/conformance tests and document Codex-specific coverage before expanding that... lifestyle coverage.

   Since #22 is still open–would you prefer that I base the work directly on #22 and submit #89 as a stacked PR, or develop against that locally and rebase onto integration once #22 lands?

   Thanks.
