+> [!NOTE]
+> **Exomind fork status**
+> This fork tracks `openai/codex` and carries a small set of workflow-level changes on top of upstream.
+> - README section updated on `2026-03-07`
+> - Latest `upstream/main` observed at update time: `9a4787c24`
+> - Current fork/upstream merge-base: `b6d43ec8`
+> - Fork-specific additions currently include:
+>   - a shared pending-input queue for repeating queue and repeating steer messages, with distinct preview colors
+>   - `Shift+Tab` cycling collaboration mode when the composer is empty, and enqueuing a repeating queue message otherwise
+>   - `Alt+↑` recalling the most recently enqueued queue or steer draft by enqueue order
+>   - Termux compatibility work and a stable Android build path
+>   - fork-specific CI compatibility adjustments plus governance/task-tracking experiments
+> - When this block changes, update the `upstream/main` hash in the same PR so the fork baseline stays auditable
