…ompact PostCompact is not a valid hookEventName inside hookSpecificOutput — Claude Code only accepts PreToolUse, UserPromptSubmit, and PostToolUse there. Using systemMessage at the top level is the correct way to inject context after compaction, and avoids the "Hook JSON output validation failed" error.
