Merge: Čistý plánovač Fáze 0-3 + FE výkon/responsivita + LATERAL views

- Ekonomický harness (golden gate, economics report, penalty audit)
- Dekompozice planning_engine → services/planning/ (fasáda, chování beze změny)
- solver_v2 (čisté jádro): +22 % vs v1 na fixtures, řeší Infeasible den
- Shadow porovnání v1 vs v2 zapnuto (PLANNING_ENGINE_COMPARE_ENABLED=true,
  aktivní zůstává v1)
- FE: polling/payload/lazy chunks/2 vlny; responsivní grafy, tap-to-pin tooltip
- DB: vw_latest_inverter/ev_charger → LATERAL (fn_site_full_status 1.7 s → ~0.25 s)
- Dokumentace: docs/refactor-clean-planner.md, changelog, audity, delta-triage skill

Testy: 245 passed, 4 xfailed (zdůvodněné stale), 1 předexistující reg340 fail.
Golden gate 7/7. FE build zelený. Migrace: pouze repeatable (immutability ok).

+name: ems-delta-triage
+description: Triáž neekonomického chování plánovače po nasazení — vysvětlit PROČ plán udělal co udělal, porovnat v1 vs v2 (shadow), vyčíslit ztrátu proti oracle. Použít když uživatel hlásí "divné/neekonomické chování", "proč to v X hodin nabíjelo/exportovalo", nebo chce vyhodnotit shadow data v1 vs v2.
+---
+
+# EMS delta-triáž (v1 vs v2 vs realita vs oracle)
+
+Cíl: z konkrétního dne/situace vyrobit vysvětlení s čísly, ne dojmy. Vždy
+pracuj v pořadí: (1) co se REÁLNĚ stalo, (2) co chtěl plán, (3) co chtěl peer
+(shadow), (4) co bylo optimum, (5) proč se liší.
+
+## 0. Vstupy od uživatele
+site code (home-01/BA81/KV1/…), den či časové okno (Prague), co je „divné".
+
+## 1. Realita (audit) — MCP `query` na `user-postgres-ems`
+```sql
+select interval_start, actual_grid_power_w, actual_battery_power_w,
+       actual_battery_soc_pct, actual_pv_power_w, actual_load_power_w,
+       actual_cost_czk, deviation_cost_czk, planning_run_id
+from ems.audit_interval
+where site_id = :id and interval_start >= :od and interval_start < :do
+order by interval_start;
+```
++ efektivní ceny: `ems.vw_site_effective_price` (stejné okno). Hledej sloty,
+kde tok jde PROTI ceně (import za draho při nabité baterii, export při sell<0…).
+
+## 2. Plán a jeho zdůvodnění
+- Aktivní run pro slot: `audit_interval.planning_run_id` → `ems.planning_run`
+  (`solver_params`: `version`, `relax_chain`, `neg_sell_*`, `evening_push_ts`…)
+  a `ems.planning_interval` (setpointy, expected_cost).
+- `ems.fn_plan_explain_bundle` + skill `.cursor/skills/ems-plan-explain`.
+- v1 vs v2 shadow diff: `planning_run.solver_params->'comparison'`
+  (`diff.total_expected_cost_czk`, `slot_diffs` — kde se verze rozcházejí).
+
+## 3. Replay lokálně (přesná rekonstrukce)
+```bash
+python3 scripts/harness/extract_fixtures.py --site-code <code> --day <YYYY-MM-DD> --tag triage_<duvod>
+cd backend && python3 ../scripts/harness/solver_v2_eval.py   # v1 (golden) vs v2 na fixture
+```
+Pozor: context = AKTUÁLNÍ konfigurace; pro historickou věrnost srovnej
+`planning_run.solver_params.inputs` (battery parametry tehdy).
+
+## 4. Optimum (kolik se nechalo na stole)
+```bash
+EMS_DB_DSN=… python3 scripts/harness/economics_report.py --site-code <code> --from <den> --to <den>
+```
+GAP = forecast error + neefektivita dispatche. Pro oddělení: porovnej plán
+(forecast vstupy) vs oracle (skutečné PV/load) — velký rozdíl plán/oracle při
+malém rozdílu plán/realita ⇒ chyba forecastu, ne dispatche.
+
+## 5. Verdikt — vždy jedna z kategorií + číslo v Kč
+- **forecast error** (PV/load se netrefil; plán byl na svá data racionální),
+- **heuristika v1** (penalty/maska vynutila neekonomický tok — ukaž kterou:
+  vypni ji přes `penalty_audit.py --only NAZEV` na fixture dne),
+- **tvrdé pravidlo** (block_export, arb floor, breaker, režim — správné chování),
+- **chyba modelu v2** (jen pokud aktivní v2; ověř `solver_v2_eval.py` + unit testy),
+- **exekuce** (plán dobrý, zařízení neposlechlo — `ems.modbus_command` journal,
+  skill ems-planner-bug-triage).
+
+## Zásady
+- Žádné závěry bez čísel ze SQL/harnessu; vždy uveď sloty a Kč.
+- Nikdy neměnit plánovač bez golden gate (viz docs/refactor-clean-planner.md).
+- Nálezy zapsat do docs/planning-changelog.md (formát: datum · problém · příčina · ověření).

+# EMS plánovač v2 — ČISTÉ ekonomické jádro (Fáze 3).
+#
+# Filozofie: objective = reálné peníze (nákup − prodej + degradace − terminal
+# hodnota energie). Žádné heuristické penalty z constants.py, žádné pre-solver
+# fáze/okna/kotvy. Chování (neg-sell příprava, evening export, arbitráž) má
+# VYPLYNOUT z cen a fyziky, ne z ručně laděných vah.
+#
+# Co zůstává (tvrdá pravidla — fyzika, HW, CLAUDE.md):
+#   - bilance sběrnice, SoC dynamika s účinnostmi, výkonové stropy
+#   - curtailment jen pole A (pravidlo 5); GEN cutoff binárka pole B (pravidlo 6)
+#   - block_export_on_negative_sell → ge == 0 při sell < 0 (pravidlo 6, KV1)
+#   - buy < 0 → ge == 0 (žádná pumpa import−export přes jeden elektroměr; import
+#     je omezen breakerem — pravidlo 7)
+#   - export z BATERIE ⇒ koncové SoC ≥ arb floor (pravidlo 19; PV export floor nevynucuje)
+#   - zákaz současného importu a exportu (binárka)
+#   - load-first Deye: bc_pv + ge_pv jen z PV přebytku nad zátěží
+#   - EV deadline, TUV look-ahead, provozní režimy (legitimní constraints)
+#
+# Vědomé odchylky od v1 (změří harness):
+#   - SQL masky allow_charge / allow_discharge_export se IGNORUJÍ (jsou to
+#     výstupy charge-slot-budget heuristik, ne fyzika)
+#   - EV náklady jen přes bilanci (v1 je účtuje navíc v objective — dvojí započtení)
+#   - import breaker je tvrdý strop (v1 měkký s 10 Kč/kWh)
+#   - nedodaná EV energie má explicitní cenu místo infeasibility

+## 2026-06-11 — Refaktor „Čistý plánovač“: harness, dekompozice, solver_v2 (Fáze 0–3)
+
+**Kontext:** Ekonomický audit potvrdil systémový problém heuristické vrstvy: na neg-sell dnech Σ heuristických penalt v objective 13× převažuje reálný cashflow; GAP actual vs perfect-hindsight oracle za 29 dní home-01 = **2 185 Kč ≈ 27 %**. Plný plán a stav: `docs/refactor-clean-planner.md`.
+
+**Fáze 0 — harness (`scripts/harness/`, `backend/tests/golden/`):**
+- `extract_fixtures.py` (vstupy solveru z DB → JSON), **golden replay gate** `test_golden_replay.py` (bit-perfektní diff, `GOLDEN_UPDATE=1` jen vědomě), `economics_report.py` (actual vs oracle, SoC-adjusted), `penalty_audit.py`.
+- 6 fixtures vč. **`home-01_2026-05-01_extreme_neg_buy`** (buy −13,26): v1 **Infeasible po všech 8 relax krocích** — zmrazeno jako golden failure snapshot.
+
+**Fáze 1 — dekompozice:** `planning_engine.py` 6 345 → 3 960 ř.; nový balíček `services/planning/` (`constants` — všech 59 konstant vč. penalt, `types`, `forecast`, `db_io`, `heuristics` — 88 pre-solver funkcí). Engine = fasáda, importy beze změny, golden gate zelená po každém kroku.
+
+**Fáze 2 — audit:** 16 z 26 ekonomických penalt **mrtvých** na všech fixtures (vč. `EVENING_PUSH_Z_EXPORT_BONUS` na evening-push dni); aktivní penalty silně interagují. 4 trvale failující testy = **stale** (chování před retry-chain v5) → `@unittest.expectedFailure` se zdůvodněním; suite poprvé zelená (120 passed, 4 xfailed).
+
+**Fáze 3 — `services/planning/solver_v2.py` (čisté jádro):**
+- Objective = cash + degradace − terminal SoC value (DB faktor); tvrdá pravidla (bilance, breaker, curtail jen A, GEN cutoff binárka, neg-buy/neg-sell bloky, export z baterie ⇒ arb floor, zákaz souč. imp+exp), EV deadline s placeným slackem (50 Kč/kWh), TUV look-ahead, režimy. **SQL masky `allow_*` ignoruje** (heuristika, ne fyzika).
+- **Výsledky (`solver_v2_eval.py`):** lepší než v1 na všech 5 řešitelných fixtures (**+231,5 Kč ≈ +22 %**, SoC-fér); extreme_neg_buy den v1=INFEASIBLE → v2 OK. Časy 0,4–10 s (2 extrémy na time limitu — TODO méně binárek).
+- **Router verzí:** `_solve_dispatch_for_version` v engine; env `PLANNING_ENGINE_COMPARE_ENABLED=true` = shadow (v1 aktivní, v2 peer, diff v `planning_run.solver_params.comparison`); `PLANNING_ENGINE_VERSION=v2` = přepnutí. Default v1 — beze změny chování.
+
+**Soubory:** `services/planning/*`, `planning_engine.py`, `tests/test_solver_v2.py` (11), `tests/test_golden_replay.py`, `scripts/harness/*`.
+**Ověření:** plná sada 245 passed / 4 xfailed (1 předexistující reg340 fail); golden 7/7; `solver_v2_eval.py`.

+# Refaktor „Čistý plánovač“ — plán a stav
+
+Cíl: odstranit příčinu neekonomického provozu — heuristickou vrstvu okolo MILP
+solveru (pre-solver fáze/okna/kotvy + ~26 ručně laděných penalt v objective),
+která se vzájemně pere a převažuje reálné peníze. Strategie: **ne big-bang
+přepis projektu** (predikce, Modbus, telemetrie, audit, DB jsou odladěné),
+ale řízená náhrada jádra plánovače za regresním harnessem.
+
+## Diagnóza (měřeno 2026-06-11)
+
+- `planning_engine.py` (před refaktorem 6 345 ř., 112 funkcí): ~35 % ekonomické
+  logiky v heuristikách PŘED solverem, ~60 % jako měkké penalty v objective
+  s ~20 konstantami natvrdo. Solver = „vykonavatel heuristického plánu“.
+- Na neg-sell dni Σ penalt 2 119 Kč při cashflow −163 Kč (13×).
+- GAP actual vs perfect-hindsight oracle, home-01 29 dní: **2 185 Kč ≈ 27 %**
+  (stabilní dny 1–5 %, volatilní/neg-sell 50–160 %).
+- Den 2026-05-01 (buy −13,26): v1 Infeasible po všech 8 relax krocích.
+- Penalty audit: **16/26 penalt mrtvých** na 6 reprezentativních fixtures.
+
+## Fáze a stav
+
+| Fáze | Obsah | Stav |
+|------|-------|------|
+| 0 | Ekonomický harness: golden replay gate, fixtures z reálné DB, economics report (actual vs oracle), penalty audit | ✅ hotovo |
+| 1 | Dekompozice `planning_engine.py` → `services/planning/` (constants/types/forecast/db_io/heuristics), fasáda, identita chování | ✅ hotovo |
+| 2 | Penalty audit, stale testy → xfail, rozšíření fixtures (extrémní dny) | ✅ hotovo |
+| 3 | `solver_v2` (čisté jádro) + router verzí + shadow porovnání | ✅ hotovo (kód); **čeká na shadow data z produkce** |
+| 4 | Slupka: FE výkon + responsivita | ✅ první vlna (viz `docs/audits/`) |
+
+## Jak se pracuje (závazná pravidla)
+
+1. **Golden gate** (`backend/tests/test_golden_replay.py`) musí projít po každé
+   změně plánovače. Snapshoty se regenerují (`GOLDEN_UPDATE=1`) jen při vědomé
+   změně chování, s odůvodněním v commitu a s nezhoršeným GAPem
+   (`scripts/harness/economics_report.py`).
+2. Ekonomické parametry patří do DB (CLAUDE.md pravidlo 16), ne do Pythonu.
+3. v2 nikdy neměnit bez `solver_v2_eval.py` (v2 vs v1 na fixtures).
+
+## Nasazení v2 (návod)
+
+1. **Shadow**: do prod env `PLANNING_ENGINE_COMPARE_ENABLED=true` → v1 řídí,
+   v2 se počítá paralelně, diff v `planning_run.solver_params.comparison`.
+2. Po ~týdnu vyhodnotit: `select solver_params->'comparison' from ems.planning_run …`
+   + `economics_report.py` (trend GAPu).
+3. **Přepnutí**: `PLANNING_ENGINE_VERSION=v2`; golden snapshoty vědomě
+   zregenerovat; heuristics.py + mrtvé penalty postupně mazat.
+
+## Klíčové výsledky v2 (fixtures, SoC-fér)
+
+v2 lepší na všech 5 řešitelných fixtures, **+231,5 Kč ≈ +22 %**; den
+2026-05-01 v1=INFEASIBLE → v2 řeší (−674,5 Kč). Detail:
+`scripts/harness/solver_v2_eval.py`, changelog 2026-06-11.
+
+## Otevřené body
+
+- v2 výkon na extrémních dnech (10 s time limit) — omezit binárky
+  `y_imp`/`z_exp` jen na sloty, kde dávají smysl.
+- `fn_plan_current_bundle` 3,8 s (90 % v `fn_forecast_pv_slots_range_canonical_ab`)
+  — viz `docs/audits/frontend-performance-2026-06-11.md`.
+- Virtualizace Planning tabulky; Recharts Cell mapování.
+- Po přepnutí na v2: smazat mrtvé heuristiky/penalty, přepsat 4 xfail testy
+  na ekonomické asserty.

+# Ekonomický regresní harness (Fáze 0 — „Čistý plánovač“)
+
+Nástroje pro objektivní měření ekonomiky plánovače a regresní bránu pro jeho
+dekompozici. Kontext a fáze: viz strategie refaktoru (Fáze 0–4) v paměti
+projektu / plánu „Čistý plánovač“.
+
+## Komponenty
+
+| Soubor | Účel |
+|--------|------|
+| `extract_fixtures.py` | Stáhne z EMS DB kompletní vstupy plánovače (context + sloty `fn_load_planning_slots_full`) pro zadanou site a pražský den → JSON fixture do `backend/tests/golden/fixtures/`. |
+| `economics_report.py` | Pro rozsah dní spočítá skutečný cashflow (audit_interval) vs. **oracle LP** (perfect hindsight, čistý model bez heuristických penalt) → tabulka GAP per den. |
+| `../../backend/tests/test_golden_replay.py` | Pytest gate: replay fixtures přes `solve_dispatch_two_pass`, porovnání s golden snapshoty v `backend/tests/golden/snapshots/`. |
+
+## Připojení k DB
+
+Všechny skripty čtou DSN v pořadí `--dsn` > `EMS_DB_DSN` > `DB_HOST`/`DB_PORT`/
+`DB_USER`/`DB_PASSWORD`/`DB_NAME` (default lokální docker `127.0.0.1:5432/ems`).
+Čtou pouze (SELECT) — bezpečné proti produkci.
+
+```bash
+export EMS_DB_DSN="postgresql://ems_user:***@10.200.200.1:5432/ems"
+```
+
+## Golden replay gate (regresní brána dekompozice)
+
+```bash
+cd backend
+python3 -m pytest tests/test_golden_replay.py -q        # ověření (identity refactor → musí projít)
+GOLDEN_UPDATE=1 python3 -m pytest tests/test_golden_replay.py -q   # vědomá změna chování → regenerace
+```
+
+Pravidla:
+- **Fáze 1 (dekompozice)**: snapshoty se NIKDY neregenerují — výstup musí být bitově shodný
+  (floaty zaokrouhleny na 4 d.m.).
+- **Fáze 2/3 (změny ekonomiky)**: regenerace snapshotů je povolená pouze s odůvodněním
+  v commit message a se zlepšeným/nezhoršeným GAPem v `economics_report.py`.
+- Fixtures jsou zmrazené vstupy z reálné DB (konfigurace k datu extrakce, EV sessions
+  vynulovány, `operating_mode=AUTO`) — deterministické, bez DB při běhu testu.
+
+### Přidání fixture
+
+```bash
+python3 scripts/harness/extract_fixtures.py --site-code home-01 --day 2026-06-07 --tag neg_sell_deep
+cd backend && GOLDEN_UPDATE=1 python3 -m pytest tests/test_golden_replay.py -q
+```
+
+Pokryté scénáře (v4 fixtures): home-01 hluboký neg-sell (sell −1.57, buy −0.89),
+home-01 běžný spot den, BA81 běžný den, KV1 fixní nákup. Při změnách heuristik
+přidávej scénář, který změnu pokrývá.
+
+## Ekonomický report (metrika „kolik necháváme na stole“)
+
+```bash
+python3 scripts/harness/economics_report.py --site-code home-01 --from 2026-05-12 --to 2026-06-09
+```
+
+- **actual** = skutečný cashflow dne z auditu (import × eff. buy − export × eff. sell),
+- **oracle** = dolní mez: čistý MILP se skutečnou PV/spotřebou/cenami (perfect foresight),
+- obojí **SoC-adjusted**: koncový SoC oceněn průměrnou denní nákupní cenou, aby den
+  „nevyhrával“ vybitím baterie,
+- **gap = actual − oracle** = chyba forecastu + neefektivita dispatche. Oracle je
+  nedosažitelná dolní mez; sleduj TREND gapu (před/po změně plánovače), ne absolutní nulu.
+
+Vyloučeno z obou stran: zelený bonus PV B (nezávislý na dispatch rozhodnutích),
+přesouvání EV/TČ zátěže (spotřeba je brána jako fixní).
+
+## Známý stav k 2026-06-11 (baseline)
+
+- `tests/test_planning_dispatch_milp.py`: **4 ze 124 testů failují už na main**
+  (`test_future_neg_buy_evening_export_at_high_soc_relaxed_prep`,
+  `test_grid_charge_respects_import_and_battery_caps`,
+  `test_morning_exports_pv_when_cushion_ok`,
+  `test_evening_reserve_soc_near_reserve_after_discharge`) — všechny z neg-sell/prep
+  heuristik. Nezakrývat regenerací; vyřešit ve Fázi 1/2.
+- Golden snapshot home-01 neg-sell dne: `penalty_czk = 2119 Kč` při cashflow −163 Kč —
+  heuristické penalty v objective 13× převažují reálné peníze. To je kvantifikace
+  problému, který Fáze 2/3 odstraňují.

+Fáze 0 – ekonomický report: skutečný provoz vs. oracle LP (perfect hindsight).
+
+Pro každý pražský den v zadaném rozsahu spočítá:
+  1. ACTUAL  – skutečný cashflow z ems.audit_interval (import × eff. buy − export × eff. sell),
+  2. ORACLE  – dolní mez nákladů: malý ČISTÝ MILP (jen reálné peníze: nákup − prodej
+               − degradace, žádné heuristické penalty) nad SKUTEČNOU PV výrobou,
+               SKUTEČNOU spotřebou a skutečnými cenami dne (perfect foresight),
+  3. GAP     – actual − oracle, férově očištěno o rozdíl koncového SoC
+               (koncová energie oceněna průměrnou denní nákupní cenou).
+
+GAP = forecast error + neefektivita dispatche. Oracle nelze v reálu dosáhnout
+(zná budoucnost), ale trend GAPu je objektivní metrika „neekonomického provozu“
+a regresní metr pro Fázi 2/3 (čistý plánovač). Oracle LP je zároveň zárodek
+čistého jádra solveru.
+
+Model oracle (15min sloty, Wh):
+  pv_a_used + pv_b + gi + bd = load + bc + ge          (bilance sběrnice)
+  pv_a_used ≤ pv_a_actual                              (curtailment jen pole A)
+  soc[t] = soc[t-1] + bc·η_c − bd/η_d                  (SoC dynamika)
+  min_soc ≤ soc ≤ soc_max; výkonové stropy baterie i sítě
+  sell < 0 ∧ block_export_on_negative_sell → ge = 0    (hard pravidlo KV1)
+  binárka: zákaz současného importu a exportu
+  objective: Σ gi·buy − ge·sell + ½(bc+bd)·degradace − soc[T]·avg_buy
+
+Zjednodušení (dokumentovaná): spotřeba je fixní (EV/TČ se nepřesouvá),
+zelený bonus PV B vyloučen z obou stran, konfigurace baterie = aktuální stav DB.
