+# TB-007 — Romhacks → RomM handoff
+
+**Status:** not started  
+**Your call:** _(unset — talk first)_
+

+
+## Talk first
+
+> **Stop.** Don't read Reference until we've talked.
+> In chat, say **"let's do TB-007"** or **"romhacks → romm handoff"**.
+
+**In one sentence:** Finish the pipeline so downloaded ROM hacks land in RomM with cover art.
+
+**Why it came up:** Orchestrator + JDownloader exist; moving files into the library isn't built yet.
+
+### Questions
+
+1. Is the Discord/JDownloader pipeline armed, or still theoretical?
+2. Worth finishing before arming, or drop the whole romhacks stack?
+3. How much automation vs 'I'll move files manually'?
+
+### Your options
+
+| Option | Meaning |
+|--------|---------|
+| **Do it** | We're doing this — I'll implement or walk you through it |
+| **Later** | Keep on the list, not now |
+| **Drop** | Remove from plan — totally fine |
+| **Tweak** | Change scope; tell me how |

+
+### If we do it — rough steps
+
+1. Complete handoff.py — incoming → Emulation/roms/<platform>
+2. RomM custom cover API
+3. Test with one staged folder
+
+### Done when
+
+- [ ] Test ROM in RomM after handoff
+- [ ] DRY_RUN still safe
