From d8ae1e588f4369bf98bd1903b624fdc792fc3c26 Mon Sep 17 00:00:00 2001 From: Nathan Schram <5553883+nathanschram@users.noreply.github.com> Date: Sun, 22 Mar 2026 13:29:24 +1100 Subject: [PATCH 1/5] fix: prevent Codex/OpenCode headless hangs (#184, #183) Codex (#184): always pass --ask-for-approval in headless mode. Default to "never" (auto-approve all) so Codex never blocks on terminal input. Safe permission mode still uses "untrusted". OpenCode (#183): surface unsupported JSONL event types as visible Telegram warnings instead of silently dropping them. When msgspec DecodeError occurs, _extract_event_type() tries to parse the raw JSON for the type field. If extractable, a warning ActionEvent is emitted (visible in Telegram) instead of returning [].
