[CLAUDE] Skill: adopt Harness 5 (model-fallback) + Harness 6 (governed-ultracode) via adap-apply + email ai_infra

- H5 model-availability-fallback: SE da de-facto fallback Fable->Opus 4.8 1M (Fable down 06-12); book caveat agents/README + H5.1 check session-start BUOC 0.6; KHONG RCA/memory-permanent (external outage). adap-report 2026-06-13.

- H6 governed-ultracode: H6.1 auto-HMW mode-ON (ultra-on + session-start T4) + H6.2 hmw.js role-less default 'opus'->inherit lead; H6.7 role/memory-fidelity da san tu S49 (document). adap-report 2026-06-15.

- /send-email ai_infra: harness-5-6-adopt-report (content_sha256 8a247984 spec-canonical self-verified, fixes S58 mis-stamp) + _index OUTBOUND.

- Gate: em main self-gate (governance doc-work; SELF-CHECK 2 broadcasts + grep-verify). CI runs (hmw.js not paths-ignore) - passes, no app-code change.
