+# KEEP vs DROP — OpenKKnD amanita pull (TODO=361 / 023-kknd)
+# Built: Director shell (Sparmodus); MERGE into _hernani-private/openkknd 2026-09-16
+# Amanita origins DELETE_OK 2026-09-16 (Freigabe chat) · no Godot openkknd2 auto-merge · no push without Freigabe
+
+## KEEP (live under _hernani-private/openkknd/ — Freigabe flatten-as-subdirs)
+
+| Subdir | Origin |
+|--------|--------|
+| `engine-c/` | vx-openkknd/ (C11+SDL2) |
+| `MISSIONS/` | MISSION.md from openkknd-{qwen,hermes,qwen14b,deepseek} |
+| `openkknd2-am-coder/` | unique trail (no build/) |
+| `kknd2-runs/` | historical run logs |
+| `llm-configs-openkknd2/` | amanita llm-configs openkknd2 notes |
+
+Staging copy still under `$HOME/git/llm/llm-work-input/openkknd-amanita-pull/_keep/`.
+
+## DROP (leave in staging; do not promote; amanita delete only after human Freigabe)
+
+- Full trees openkknd-{qwen,hermes,qwen14b,deepseek} except MISSION.md — near-dup C vs vx-openkknd
+- Binary rebuild optional (`openkknd` / `openkknd_dbg`) — rebuild via `engine-c/build.sh` on Linux
+- Empty asset placeholders if unused
+- `openkknd2-am-coder/build/` object junk
+
+## DO NOT
+
+- Litter Pitchwell **root** with C sources — keep under `engine-c/` only (subdirs OK; root flatten = no)
+- Auto-merge am-coder into Godot `$HOME/git/src/openkknd2`
+- Re-create amanita openkknd\* trees without need (DELETE_OK done)
+- Treat C-engine as “orthogonal forever” — **superseded**: one RTS tree = `_hernani-private/openkknd` with `engine-c/` + kitchen
+
+## Proposal (text only)
+
+Dauerhome: subdirs under `_hernani-private/openkknd/`. Separate `openkknd-c-engine/` repo **not** required unless human reopens Decide.
