Подтверждённые received0/sent4 остаются100%/down с RTTnull; успешный настоящий RTT0/loss0 сохранён. Scheduled и manual collectors различают успешное измерение и ошибку REST/недостаточный ответ; after-bandwidth Ping при неизвестном результате возвращает null metrics/error, а не выдуманный outage. Alert decoder принимает только ok=true и известное состояние; retained legacy ok=false/down/100 не срабатывает как измеренная потеря. Malformed due-probe rows без ID — barrier, не разрешение восстановить старое измерение.
+
+Миграция0010 добавляет uptime_probe_samples.measurement_known boolean defaulttrue и observation_error text; CHECK/legacy storage status и integer loss не ломаются. Raw100/down в failed rows — прежние storage sentinel с явным measurement_known=false, не публичное измерение. Snapshot/public observations/API loss становятсяnull/statusunknown, есть причина ошибки. Новые flags пишутся при scheduled и manual error/empty response. Старые scheduled failure samples переклассифицируются readonly по точному probeId+sampledAt retained v1 JSON provenance; genuine100% без failure flag не меняется. Старые manual/retention-lost failures без provenance надёжно восстановить нельзя: они остаются legacy ambiguity, полного historical cleanup не заявляем. Migration additive, прошлые данные не удаляет; source JSON internal v1 теперь допускает nullable loss/unknown. Для rollback старый код не интерпретирует measurement_known, поэтому совместимость хранения не означает корректное чтение новых unknown attempts старой версией.
+
+Overview выдаёт unknown/null без fallback100/down и без padded historical0. Observations timestamps канонизированы; parser проверяет согласованность unknown/null. /uptime использует тот же observed decoder, что dashboard: «Нет данных», — для RTT/loss, причина execution error, отдельный filter/URLstatus=unknown. Новая draft probe тоже не объявляется заранее up/0. Мини-Sparkline сохраняет gaps; expanded RTT chart больше не превращаетnull в0 и не дублирует одиночную точку для выдуманной линии. Dashboard status tooltip получает причину. Source/speed-interface read endpoints теперь409 до RouterOS при disabled server; ошибочная подпись «для ping всё равно можно выбрать выключенный» исправлена.

 ## 12.5.172 — подтверждённые текущие проблемы в журнале мониторинга (2026-10-12)
 
 Внешнее воспроизведение выполнено на compiled ux-targets171 с own PostgreSQL/ограниченной ролью. Прежний overview принимал положительный raw sample и корректно выдавал timestamp string: гипотеза Date/schema failure НЕ подтвердилась. Первая baseline попытка ожидала ошибку и завершилась assertion failure; её результат сохранён, own fixture/DB/role очищены. Уточнённый baseline прошёл: один и тот же live offline оставался после disabled server, disabled resources source и замены sampledAt на часовой давности. Это положительное независимое подтверждение реального disabled/freshness дефекта прежней ветки, не вывод только из кода.

Scheduled и manual collectors различают успешное измерение и ошибку REST/недостаточный ответ; after-bandwidth Ping при неизвестном результате возвращает null metrics/error, а не выдуманный outage. Alert decoder принимает только ok=true и известное состояние; retained legacy ok=false/down/100 не срабатывает как измеренная потеря.

Raw100/down в failed rows — прежние storage sentinel с явным measurement_known=false, не публичное измерение. Snapshot/public observations/API loss становятсяnull/statusunknown, есть причина ошибки. Новые flags пишутся при scheduled и manual error/empty response. Старые scheduled failure samples переклассифицируются readonly по точному probeId+sampledAt retained v1 JSON provenance; genuine100% без failure flag не меняется. Старые manual/retention-lost failures без provenance надёжно восстановить нельзя: они остаются legacy ambiguity, полного historical cleanup не заявляем. Migration additive, прошлые данные не удаляет; source JSON internal v1 теперь допускает nullable loss/unknown. Для rollback старый код не интерпретирует measurement_known, поэтому совместимость хранения не означает корректное чтение новых unknown attempts старой версией.

+## 12.5.173 — ошибка Ping не подменяет измеренные потери (2026-10-12)
+
+Завершён целый раздел producer→SQL→API→UI. parsePing теперь возвращает measured: empty/unsupported replies, zero sent и противоречивые/malformed counts не подтверждают процент потерь. Подтверждённые received0/sent4 остаются100%/down с RTTnull; успешный настоящий RTT0/loss0 сохранён. Scheduled и manual collectors различают успешное измерение и ошибку REST/недостаточный ответ; after-bandwidth Ping при неизвестном результате возвращает null metrics/error, а не выдуманный outage. Alert decoder принимает только ok=true и известное состояние; retained legacy ok=false/down/100 не срабатывает как измеренная потеря. Malformed due-probe rows без ID — barrier, не разрешение восстановить старое измерение.
+
+Миграция0010 добавляет uptime_probe_samples.measurement_known boolean defaulttrue и observation_error text; CHECK/legacy storage status и integer loss не ломаются. Raw100/down в failed rows — прежние storage sentinel с явным measurement_known=false, не публичное измерение. Snapshot/public observations/API loss становятсяnull/statusunknown, есть причина ошибки. Новые flags пишутся при scheduled и manual error/empty response. Старые scheduled failure samples переклассифицируются readonly по точному probeId+sampledAt retained v1 JSON provenance; genuine100% без failure flag не меняется. Старые manual/retention-lost failures без provenance надёжно восстановить нельзя: они остаются legacy ambiguity, полного historical cleanup не заявляем. Migration additive, прошлые данные не удаляет; source JSON internal v1 теперь допускает nullable loss/unknown. Для rollback старый код не интерпретирует measurement_known, поэтому совместимость хранения не означает корректное чтение новых unknown attempts старой версией.
+
+Overview выдаёт unknown/null без fallback100/down и без padded historical0. Observations timestamps канонизированы; parser проверяет согласованность unknown/null. /uptime использует тот же observed decoder, что dashboard: «Нет данных», — для RTT/loss, причина execution error, отдельный filter/URLstatus=unknown. Новая draft probe тоже не объявляется заранее up/0. Мини-Sparkline сохраняет gaps; expanded RTT chart больше не превращаетnull в0 и не дублирует одиночную точку для выдуманной линии. Dashboard status tooltip получает причину. Source/speed-interface read endpoints теперь409 до RouterOS при disabled server; ошибочная подпись «для ping всё равно можно выбрать выключенный» исправлена. Это соответствует прямому правилу пользователя не опрашивать выключенные устройства любых типов. UI/ReUI primitives/theme не заменены.

+Unit parser/observations/frontend dashboard-probes/URL guards прошли; backend build, application-source TypeScript и ESLint прошли (в uptime-collector два прежних unused settings warnings, functional scope не расширен). Первый npm --prefix exec взял неверный cwd, повтор direct tsx корректен; новый тест сначала использовал неверное имя Zod package, исправлен на установленный @fastify/type-provider-zod. Local cancellation test получил sandbox EACCES, разрешённый сетевой профиль прошёл; local own SQL skipped без выделенной базы.85 unique E2E Uptime/Ping/Speed: initial83passed/2failed были новые ambiguous test selectors (имя есть в sidebar и строке); selector исправлен на конкретную причину ошибки, delta3passed9.5s. Existing83 scenarios повторно не запускались;2 screenshot captures passed8.5s отдельно. Это не85 clean single-run и не87 новых сценариев. Два перезаписанных тестами прежних speed images восстановлены SHA256;8 user dirty GRE/VXLAN images не тронуты. Новые снимки просмотрены, nullable состояние читаемо при320px.
+
+Owned Node22/PG18.6 профили alert-engine+probes прошли42380ms:26 source/history SQL cases, GRE/BGP8/actual stability и8 новых Ping cases. Последние проходят через реальный MikrotikClient HTTP к loopback simulator, persisted flags, GET overview Fastify path:401,empty,manual,real loss/zero,API,legacy exact provenance и disabled no-outbound requests. Simulator не является физическим RouterOS/network failure. Финальные unit guards zero/inconsistent counts/malformed probe проверены перед scoped rerun; temporary DB/role/container удалены. Production credentials/JWT не копировались. Type/producer tests подключены к стандартному test:probes; default profile count не увеличен.
+
+Source440 backend+518 frontend inputs/1020 emitted parity совпали SHA256. Both production builds passed, backend image включает новый drizzle0010. Staged deploy: frontend ux-ping173 сначала принял старый API ux-history172, затем backend ux-ping173/version1.0.0-test.ping173. Migration0010 и2 новых columns подтверждены readonly в main PG. Backend/PG healthy, frontend running/HTTP/UI, imageIds verified, running containers3. В.env менялись толькоimage tags; rollback tags сохранились отдельно без secret env копии. Cached прежний frontend следует перезагрузить: новые nullable/unknown DTO требуют совместимого reader.

+Следующий174 — audit first-wave/invalid traffic rate confidence: ok request и numeric sum не всегда доказывают измеренный rate без previous wave. Не заявлять эту гипотезу как уже выполненное исправление.
