Инвентарь тулов жил в 4 рукописных прозаических копиях (SERVER_INSTRUCTIONS под regex-тестом; ; имена в ai-chat.prompt.ts без гарда; README) — роадмап #416 планировал 4 последовательных ручных правки этого текста (#411/#412/#413/#415). - SERVER_INSTRUCTIONS разбит (новый модуль server-instructions.ts): ROUTING_ PROSE (рукописные intent-подсказки «когда что» — осмысленно ручные, перенесены ДОСЛОВНО со всеми предостережениями: <=250 у create_comment, soft-delete у delete_page, baseHash у drawio_update, PUBLIC у share_page) + buildToolInventory() — генерирует из реестра (mcpName + purpose из catalogLine, группировка по TOOL_FAMILY, бакет OTHER ловит незамаппленное → тул нельзя тихо потерять) + 5 inline MCP-only (INLINE_MCP_INVENTORY). Детерминирован (семейства FAMILY_ORDER, имена localeCompare). regex-тест server-instructions удалён; структурные гарантии — в новом tool-inventory.test.mjs (точное членство множества сильнее старого \b-скрейпа). - Имена тулов в ai-chat.prompt.ts → через экспорт PROMPT_TOOL_NAMES; новый гард ai-chat.prompt.tool-names.spec.ts: каждое имя — реальный тул реестра, скан guidance-нот на camelCase-токены падает на несуществующем (escape- нейтрализация против ложных nThe-токенов). - INLINE_TOOL_TIERS уже содержал ровно 8 genuinely-inline тулов (после #445) — сжатие не потребовалось. Критерий: добавление/переименование спека меняет инвентарь БЕЗ правки прозы. Внутреннее ревью: APPROVE — фактическим прогоном подтверждено, что НИ ОДИН тул из старого SERVER_INSTRUCTIONS не выпал (диф старый-vs-новый пуст; добавился get_workspace, раньше прятавшийся в EXCEPTIONS); проза дословна; инвентарь полон/детерминирован/без фантомов; гард краснеет на обеих ветках провала. 613 node + 289 jest зелёные. Стоит на #445 — мержить последним в стопке 1б. README-каталоги вне обязательного скоупа (docs-скрипт) — в чек-лист #412.
