 | **Is it convention-ready?** | **Nearly.** The print pack is built (`CLEAN_GROUND_HANDOUTS.html`, held by `check-handouts`). What is missing is a run with human beings, and a slot. |
 | **Playtesting** | Three desk passes, all fixes applied: `CLEAN_GROUND_PLAYTEST_1.md` (GM chair, seed 4271), `_2.md` (Act Four stress, seed 9314), `_3.md` (player chair, contrarian, seed 5580). Twenty-three fixes plus one post-pass. |
 | **What it is** | A **convention one-shot**, decided 13 September 2026. It ends in the slot; there is no second session and the text must not promise one. |
+| **Where it runs** | **Contingency 2027 — Sunday 31 January 2027, afternoon** (slot 9), Searles Leisure Resort, Hunstanton. |
 | **Runtime** | 4h00 including a break. Desk pass 1 ran 4:25; the **Pacing Note** carries ~25 minutes of pre-written cuts. Take them as the default. |
 | **Players** | 4–6 from the duty roster. The cast is declared in the Casting section and the build enforces it. |
