[CLAUDE] Skill: adopt Harness-8 all-inherit (11 sub -> inherit, go two-tier H4) + email-back ai_infra

AI_INFRA broadcast 2026-06-16 (BAT BUOC, PROJECT-FIT 6/6). Flip 7 demoted subs claude-opus-4-8 -> inherit (all 11 inherit; SE has no cheap helper/gopher); agents/README + hmw.js comments codify (resolveModel defers frontmatter). adap-report + email-back (content_sha256 fa7f690d round-trip MATCH). Nac executed-file VERIFIED-pending-restart (frontmatter no hot-reload). Runtime unchanged now (inherit=Opus 4.8 1M since Fable suspended H5); forward-looking + H5.6 restore simpler.

   WRITE specialist cho toàn bộ .NET backend SOLUTION_ERP (Domain + Application + Infrastructure + Api layer). Scaffold entity + enum + EF Configuration + Migration 3-file + DbInitializer seed + CQRS Command/Query/Validator/Handler + MediatR + Controller + DTO. Case 1+2+3+5 only (cookie-cutter mechanical scaffold, multi-file independent orchestrator-workers, isolated method test-gen handler, mass migration). DO NOT touch FE 2 app (đó là implementer-frontend). DO NOT write test assertions (đó là test-specialist). DO NOT schema design / UX decision / cross-stack bug fix reasoning (em main solo). Auto-refuses out-of-scope.
