[CLAUDE] Docs: S46 memory integrity repair — sync STATUS/HANDOFF

Rebuild empty MEMORY.md index (S45 0-byte) + repopulate feedback_background_spawn_visibility + new feedback_session_end_memory_write_verify (memory files live outside repo). Fix stale user-memory count 27->14. Tier HANDOFF S43->pointer.

+## S46 (2026-06-01) — Memory integrity repair (no code, docs-only)
+
+**`/session-start` audit phát hiện S45 close-out để lại 2 file user-memory 0 byte** — `MEMORY.md` (index) + `feedback_background_spawn_visibility.md`. Index rỗng = S46 bootstrap chạy KHÔNG có memory auto-inject (degrade thầm lặng).
+
+**Done (👤 em main solo, no agent spawn):**
+- Rebuilt `MEMORY.md` index — 14 entry (8 feedback + 3 project + 2 pattern). Repopulate `feedback_background_spawn_visibility` từ HANDOFF/STATUS S45 ref (marked reconstructed). NEW `feedback_session_end_memory_write_verify`.
+- Verified **0 empty `.md`** (`find -size 0` = 0). STATUS count drift "27"→**14** corrected. Test gate re-confirm 181 PASS lúc bootstrap.
+- Memory files NGOÀI repo (`~/.claude/.../memory/`) → no git commit cho memory. Chỉ repo docs (STATUS+HANDOFF) = docs-only commit, CI skip.
+
+**Root cause:** S45 session-end flush tạo stub rồi Write body truncate (gotcha #53 — S45 có test-specialist truncate). File 0-byte không báo lỗi + ngoài git-track → trôi tới S46 mới lộ.
+
+**Next S47 (anh pick):** P11-C Vehicle+Driver (Mig 44, recon ready) · gotcha #57 fix LeaveType/Shift filtered-unique · P11-D/E/F · Phase 9 Ops · (optional) add verify-byte-count step vào /session-end skill — đề xuất AI_INFRA per charter v2.
