[CLAUDE] Docs: S87 closeout — PE multi-winner + budget=0 + cấp-KẾT-THÚC (Mig 58) + Section B 3-cột (Mig 59)

STATUS + HANDOFF S87 narrative + count flush (Migrations 57->59, test 377->402,
gotcha 73 unchanged) + session log 2026-06-24-S87 + agent-memory harvest
(cicd-monitor #344 / implementer-backend / investigator-codebase / reviewer /
test-specialist — spawn-record on-disk).

State THẬT: Mig 59 · 88 bảng (cicd flag 89 drift, re-ground monthly) · 402 test
(45D+357I) · gotcha 73 · menu 54 · bundle admin CXCKlNay/user Di40ewrF
(Run #344; #345 cicd-verifying Section B). Docs-only -> CI skip.
