Automatic compaction (`autoCompactEnabled`) summarises older parts of a conversation when it nears the context limit, the most text the model can hold at once.\n\n- This applies to child sessions tagged \"hearth-rc-child\" (role `projectThreadChild`), and only when the new switch `tengu_bridge_rc_child_auto_compact` is on. Its built-in fallback is on; nothing has been read about it.\n\n- That role now grants `autoCompact`, next to `defaultMode: \"auto\"` in the settings generated for the child.\n\n- When a session is launched, the `--settings` JSON now passes `autoCompact` alongside `autoOverSettings` and `autoModeEnvironment`, and includes `autoCompactEnabled: true` when it is granted.\n\n- At attach, if flag settings do not already set `autoCompactEnabled`, it is set to true and listed in the reported granted settings; on detach it is removed again.\n\n**Why**\n\nLong-running project-thread children can compact on their own instead of running into the context limit. Because values passed with `--settings` override the same keys in your settings files, such a child can run with auto-compact on even if you turned it off in your own settings; it is left alone only when flag settings already set `autoCompactEnabled`.\n\n- Area: Elsewhere\n- Names: `autoCompact`, `--settings`\n- Tier: You'll notice\n- Useful: 3\/5\n- Signal: 3\/5"}
