 - **Masky `allow_charge` / `allow_discharge_export` (tenký anti-mikrocyklus):** generuje `ems.fn_load_planning_slots_full` (`R__063`). Ekonomiku primárně řídí LP podle efektivních cen; masky jen omezují počet slotů pro grid nabíjení / export baterie.
   - **PV-surplus (vrstva A):** ranking dle **`store_score DESC`** = `future_sell_opportunity − sell − max(0, buy−sell)`; jen sloty s `sell ≥ buy − degradation`. Kumulativní PV pokrývá `grid_target` (deficit SoC, nad `reserve_soc` bez násobení `charge_slot_buffer`). Zbytek → `allow_charge=false` (PV jen do sítě / `bc ≤ pv_surplus` v LP).
-  - **Grid ze sítě (vrstva B, před FVE):** výchozí **AM/PM 50/50** z `grid_target × charge_slot_buffer` (do `soc_max`); **nevyčerpaný AM Wh přejde do PM** (`R__063`). **Spot:** výběr **nejlevnější `buy`** (den plánu → před exportním oknem → `buy ASC`); navíc všechny sloty s **`buy < 0`** → `allow_grid_charge`. **Fixní tarif (BA81):** stejný AM/PM rozpočet, ale pořadí podle **`slot_ord`** (buy konstantní), jen pokud v horizontu existuje **`sell > buy + degradation`**; jinak jen PV vrstva A. Cap slotů: `ceil(budget/per_slot_wh) × charge_slot_buffer`. **`charge_acquisition`:** vážený `buy` u `allow_grid_charge` před 1. exportem; two-pass v `planning_engine.py`.
+  - **Grid ze sítě (vrstva B, před FVE):** výchozí **AM/PM 50/50** z `grid_target × charge_slot_buffer` (do `soc_max`); **nevyčerpaný AM Wh přejde do PM** (`R__063`). **Spot:** výběr **nejlevnější `buy`** (den plánu → před exportním oknem → `buy ASC`); navíc všechny sloty s **`buy < 0`** → `allow_grid_charge`. Po výběru AM/PM běží **iterativní self-konzistentní filtr** (vyloučí drahé grid sloty, pokud `pv_charge_wh_ahead + neg_buy_wh_ahead >= 60 %` deficitu SoC; failsafe unlock). Debug: `grid_charge_suppressed_reason`. **Fixní tarif (BA81):** stejný AM/PM rozpočet, ale pořadí podle **`slot_ord`** (buy konstantní), jen pokud v horizontu existuje **`sell > buy + degradation`**; jinak jen PV vrstva A.

   - **PV vrstva A:** při `sell ≥ 0` jen pokud `sell ≥ future_sell_opportunity − degradation` (držet FVE na večerní peak). Při **`sell < 0`** vrstva A **bez** tohoto filtru (nabít z FVE v záporném výkupním okně). Historie: [`docs/planning-changelog.md`](../planning-changelog.md).
   - **LP (AUTO):** objective explicitně `−ge_pv×sell − ge_bat×sell + ge_bat×acquisition` v exportních slotech; **bez** cross-slot vynucení `ge_pv ≥ surplus`. Guard FVE: `ge_pv=0` jen pokud `sell < charge_acquisition − degrad` (ne `sell < buy` ve slotu). Viz [`planning-arbitrage-accounting.md`](planning-arbitrage-accounting.md).
   - **Load-first (Deye, AUTO):** proměnné `pv_ld` (PV → load+EV+TČ), `pv_sp` (přebytek), `bc_pv` / `bc_gi`. Plná bilance `pv_a + pv_b + gi + bd = load + ev + hp + bc + ge`; `bc_pv + ge_pv ≤ pv_sp`; `gi ≤ load + bc_gi`; mimo `allow_discharge_export`: `bd ≤ load − pv_ld` a **`pv_ld ≥ load − gi − bd`**. Snapshot: `load_first_enabled=true`. Test `LoadFirstDispatchTests`.

+## 2026-05-27 — self-konzistentní grid maska B + ekonomický rozpad plánu (v12)
+
+**Problém (home-01, run 16522, tag v11):** Noční grid nabíjení (23:30–23:45, buy ~4,8 Kč) při `acquisition_pass1≈4,81` / `pass2≈0,84`, `two_pass_converged=false`; 26 slotů export při `sell<0`.
+
+**Oprava (tag `2026-05-27-self-consistent-grid-mask-v12`):**
+
+- **`R__063`:** iterativní filtr vrstvy B (spot) + sloupce `pv_charge_wh_ahead`, `neg_buy_wh_ahead`, `grid_charge_suppressed_reason`, `min_buy_before_cutoff_czk_kwh`; failsafe unlock.
+- **`V081`:** `planning_interval.cashflow_czk`, `battery_arbitrage_czk`, `penalty_czk`, `green_bonus_czk`; commit přes `fn_planning_run_commit`.
+- **`planning_engine.py`:** post-processing ekonomiky, `solver_params.objective_terms` rozšíření; `fn_plan_explain_bundle` → `economics_summary`.
+
+**Ověření:** `pytest backend/tests/test_planning_economics_columns.py`, `DynamicGridFilterTests`, `Home01RegressionTests::test_home01_no_night_charge_before_pv_day`, `test_two_pass_converged_after_filter`; po deploy MCP: `grid_charge_suppressed_reason` ve `fn_load_planning_slots_full`, `two_pass_converged=true` na novém run.

 ## 2026-05-26 (o) — home-01: neg. výkup bez placeného exportu FVE + dump baterie před extrémním buy
 
 **Problém (run 16480, tag v10):** Po ranním nabití na `soc_max` solver při `sell<0` exportoval **celý PV přebytek** (~9 kW, `PV_SURPLUS`) — binárka `w_pv_full_neg` povolila `ge_pv ≤ pv_surplus` místo jen ventilu pole B. Zároveň `ge_bat=0` blokoval výboj baterie před oknem `buy ≤ −2` (round-trip arbitráž).
