+считает `ls demo/smoke_*.mjs | wc -l`, вшитое число здесь трижды отставало от
+дерева; прогон всех уместен только когда задача задевает всё; какие относятся к
+диффу, печатает
+`node scripts/smoke-select.mjs --base origin/dev --head HEAD`, и его вывод
+прикладывается к ревью вместе с решением по каждой строке), `golden:verify` при изменении видимого
 результата, `pytest tests_backend` при правках в Python, performance-профили при
 названном в AC влиянии. **Полные наборы — предрелизный гейт, а не гейт ревью.**
 
+Скриншоты снимаются **только** джобой `Docs screenshots` (`workflow_dispatch`) и
+принимаются локально: `npm run docs:accept -- --reviewed --from=<распакованный
+артефакт>` (#246). Съёмка на своей машине даёт байтово другой PNG при том же
+кадре, и набор из «не того» браузера переписывает все десять файлов без единого
+содержательного изменения. Приёмка отказывает, если кандидат снят не с этого
+дерева, не тем капчуром, не называет свой Chromium или неполон; коммит делает
+человек.
+
+`check-docs` стоит в обязательной части не по важности, а по механике: отпечаток
+скриншотов документации считается по всему `src/**`, поэтому **любая** правка
+фронтенда делает его устаревшим. Выборка «по diff и AC» здесь не работает — diff
+всегда попадает, и решать нечего. Цена пропуска измерена: скриншоты не
+пересняли в #230 и #234, и `dev` стоял с красным job `docs`, пока это не нашли
+при следующей задаче (#237). Пересъёмка — `npm run build && node
+demo/docs/capture.mjs`, коммит вместе с задачей.

 Условие честности такого сужения: ревьюер обязан перечислить, какие гейты прогнал,
 какие нет и почему. Непрогнанный гейт становится видимым решением, а не молчаливым
 пропуском.
 
+**Одно число — один источник.** Любая величина, которую пользователь видит
+дважды — превью против записи, подпись против площади, подсветка инструмента
+против сохранённого значения, — обязана считаться в одном месте. Три дефекта
+подряд имели ровно эту причину: #234 (резинка показывала 12 см, запись хранила
+24), #233 (подпись мерила по осевым линиям, площадь рядом — по полу) и способ,
+которым #234 нашли (подсветка «Толщины» врала согласованно с записью). Ревьюер
+отвечает на вопрос прямо: какое число в этом диффе видно дважды и один ли у него
+источник. Механическая часть правила закреплена тестом
+`test/single-source-numbers.test.mjs` — строку с единицей измерения собирает
+только канонический форматтер; смысловая часть остаётся за ревью.

+**Ветка приводится к `dev` до ревью, а не после** (#257). Раньше ревью читало ветку
+как есть, а слияние делало ребейз — проверенный SHA и слитый SHA были разными
+коммитами. Пока расхождение с `dev` текстовое, ребейз упирается в конфликт и это
+видно; смысловое расхождение git склеивает молча, и в `dev` уезжает комбинация,
+которую ревьюер не читал. Именно так пришёл регресс #234. Шаг перед ревью делает
+одно из трёх:
+
+- ветка уже содержит весь `dev` — ничего;
+- отстала и ребейзится чисто — ребейз, `push --force-with-lease`, ревью по
+  приведённому состоянию. Факт ребейза передаётся в промпт, чтобы сработало
+  правило §7.2 о полном разборе вместо дельты;
+- конфликт — возврат в `S6-in-progress` **до** запуска ревью. Цикл при этом не
+  расходуется: код никто не читал, вердикта нет.
+
+Проверка стоит до ревью не только ради совпадения SHA. Конфликт всё равно вернул бы
+задачу, но обнаруживался он после сорока пяти минут работы ревьюера и потраченных
+лимитов подписки, хотя виден за пять секунд до них.
+
+`--force-with-lease` здесь обязателен с явным ожидаемым значением: между чтением
+ветки и пушем автор мог запушить коммит, и слепой `--force` потерял бы его молча.
+Расхождение lease — падение прогона, а не предупреждение.
+
 Поэтому зелёное код-ревью с неудавшимся слиянием ведёт не в `S8-merged`, а в
 `S6-in-progress`: работа действительно вернулась к автору, только осталась не
 правка кода, а ребейз. Вердикт при этом в силе, переделывать нечего. После ребейза

+A full configuration is 70 KB on a real installation: three spaces and 139
+markers. Every diagnostic question — "which space does this marker point at",
+"how many markers are hidden", "what is on the first floor" — used to require
+downloading all of it, because `houseplan/config/get` had no way to ask for
+less.
+
+The functions here are pure and deliberately unaware of Home Assistant: the
+websocket handlers stay thin, and the interesting part is covered by tests that
+run without the HA harness.
+
+Two rules shape everything below.
+
+* Absent parameter means *no projection*. The response must stay byte-for-byte
+  what it was before this module existed; no existing client may notice it.
+* A projection never invents or repairs data. An unknown field name simply adds
+  nothing, and an unknown space yields an empty list rather than an error — the
+  caller distinguishes "no such thing" from "broken" by content, not by an
