+## 2026-06-06 — Pozdní replan večer: Infeasible při vysokém SoC (home-01)
+
+**Problém:** Po přepnutí na AUTO a ručním replanem (~21:00, SoC **~74 %**, zítra `buy<0` + `sell<0`): všechny retry včetně `neg_sell_phases_fallback` → **`Solver: Infeasible`**. Aktivní zůstal starý plán z 17:00 (import místo večerního vývozu k **reserve ~20 %**).
+
+**Příčina:** SQL maska `allow_charge=false` ve večerních slotech (drahý `buy`, `sell` < `buy`) + guard drahého importu vyžadoval baseload z baterie (`bd`), zatímco **v64 `future_neg_buy_discharge`** současně vynucoval večerní vývoz — LP bez rozšíření `charge_slots` neměl řešení.
+
+**Oprava (tag `2026-06-06-home01-late-replan-infeasible-v1`):**
+- Při **`future_neg_buy_discharge`**: rozšířit `charge_slots` o večerní / exportní sloty dne replanu (grid smí krmit load během vývozu).
+- Nový poslední retry **`relaxed_pos_sell_ge_block`** (+ nouzové rozšíření masek) v `SOLVER_RELAX_STEPS`.
+
+**Soubory:** `planning_engine.py`, `scripts/repro_home01_23840.py`, test `test_home01_late_replan_high_soc_realistic_masks`.
+
+**Ověření:**
+- `PYTHONPATH=backend python3 scripts/repro_home01_23840.py` → `OK two_pass`
+- `pytest backend/tests/test_planning_dispatch_milp.py -k home01_late_replan`
+- Po deployi: ruční replan v AUTO → `planning_run.status=active`, večerní sloty `grid_setpoint_w < 0`.

 ## 2026-06-06 — BA81 GEN cut-off exekuce při sell&lt;0 (Branch 4)
 
 **Problém:** Audit BA81 6. 6. 2026 (07:45–08:30, `sell<0`): plán `grid_setpoint_w=0`, `deye_gen_cutoff_enabled=false`, ale **`actual_grid_export_wh` > 0** a **`flow_pv_to_grid_wh` > 0** (~0,8–1 kW). Reg **145** (`export_ban`) nestačí — mikroinvertory na GEN portu exportují, dokud reg **178** bits 0–1 ≠ cut-off ON.
