Developer Action Items
- β Verify the claim on the official Claude / Opus / Codex page (or HN Claude/Codex/Fable), not from this recap alone.
- β Name the surface that moved β API, policy, model, hardware, or commercial terms β before you Slack the thread.
- β Assign one owner a day to read the primary material and decide: this-sprint, this-quarter, or noise.
- β Do not change production on day-one coverage. Watch the vendor changelog and one independent write-up first.
