feedback-agent-kill-recovery External kill (session-limit) / truncation / die-0-byte (resume-kill) of spawned agents → recover via on-disk/prod truth + em-main-solo fallback + curl-self-verify + evidence-checklist self-gate; agent return-message ≠ source-of-truth

Khi sub-agent bị kill (session-limit) hoặc truncate (gotcha #53) hoặc die-0-byte (resume-kill) giữa task, work KHÔNG mất — recover qua source-of-truth THẬT, KHÔNG dựa agent return-message.

Why: S52 (2026-06-08) — session-limit kill 3 agent mid-Wave-2 (FE 0-file-ghi, test file-ghi-xong-mất-report, cicd verdict-mất) + Wave-2 BE return truncated ("Now apply to LocalDB..."). TẤT CẢ recoverable vì work nằm trên disk/prod, không trong return-message. 0 việc mất, 0 prod bug. S57bis (2026-06-11) thêm class #3 "die-0-byte": 2 reviewer-spawn liên tiếp output-file 0-byte không return gì (quanh user --resume — resume-kill); CÙNG session 2 implementer return-truncated mid-task (BE chết trước migration+projection-3, FE chết giữa mirror fe-admin) → em main solo vá cross-stack + tự gate; ship sạch 240 test + prod.

How to apply:

  • Agent return = KHÔNG source-of-truth. Verify THẬT: git status/git diff (file đã ghi gì) + dotnet build/dotnet test (compile+pass) + đọc file đã sửa.
  • Killed agent để lại work-on-disk: file đã ghi + build/test pass → COMPLETE, chỉ mất report/MEMORY-step → em main proxy-append diary next.
  • Agent 0-file (killed sớm) → em main solo redo (gotcha #53-class boundary fallback, proven S37/S52 FE 2-app SHA256).
  • Die-0-byte detect (S57bis): Get-Item <output-file> size=0 + LastWrite im >5' → coi như chết, ĐỪNG đợi notification. KHÔNG spawn lại >2 lần cùng vai trong session có resume — chuyển fallback.
  • Reviewer-spawn chết ×2 → em main SELF-GATE evidence-checklist (proven S56 StructuredOutput-fail + S57bis die-0-byte): mỗi điểm hệ trọng = 1 lệnh evidence (grep key-set authz, grep role-string vs AppRoles const, đọc Mig Up/Down) + backstop independent tests; ghi HONEST "self-gate + lý do" vào commit message/log/email — không giấu.
  • cicd-monitor unavailable → em main curl-self-verify prod (health 200 → app booted → mig applied · endpoint 401-wired-not-404 · bundle-hash-rotate) thay spawn.
  • Limit pressure → giảm spawn: em-main self-review (cross-check ground-truth: seed↔query dept-code, role-string vs AppRoles) thay reviewer-spawn; curl thay cicd-spawn. Đánh đổi: mất adversarial-independence → bù bằng cross-check thủ công + build/test/curl evidence.

Mở rộng feedback-implementer-truncation-mitigation (self-truncation mid-MEMORY) sang external-kill + resume-kill. Cùng nguyên lý: git/disk/prod = truth, agent-message = không.
