[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 caught 2 user-memory files at 0 bytes** (S45 close-out truncation, gotcha #53): `MEMORY.md` index + `feedback_background_spawn_visibility.md`. Empty index = S46 bootstrap chạy KHÔNG có memory auto-inject (degrade thầm lặng).
+- **Repaired (👤 em main solo):** rebuilt `MEMORY.md` index (14 entries: 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` (verify byte>0 sau closeout Write). **0 empty `.md` remain** (verified `find -size 0`).
+- **No production/repo code touched.** Memory files ngoài repo (`~/.claude/.../memory/`) — không git-tracked → repo unchanged từ S45 `7fbe05a`. Test gate re-confirm **181 PASS** (58+123) lúc bootstrap.
+- **Residual:** STATUS "27 user memory" stale → corrected **14**. Recommend thêm verify-byte-count step vào `/session-end` skill mechanism (AI_INFRA op per charter v2) — auto-catch class lỗi này.
