p59: Sim 多世界并存后台压测(内存/GC 增长曲线证据单,只读)
目标:量化「多世界并存 × 天数」的内存/GC 增长,收口 P49 范围外项。
口径:新增 Headless `--profile-multiworld <worlds> <days> <npcs> <sampleEveryDays> <seedBase>`,
N 个 Sim 世界同时存活,每轮 Parallel.For 各推进 sampleEveryDays 天并采样一行
(worlds/events/rumors/annals/memory_entries/gc_live_mb/working_set_rss_mb/elapsed_s,
行尾 flush);未改 Kernel/Sim 任何语义(Sim.initialWorldN / Sim.step 原样调用)。
标定:1 世界 × 2 天探针 = 34.2s(与 overnight-status 的 34.6s 一致),据此定 N=10 × 20 天。
运行:独立 systemd --user transient unit living-village-multiworld.service
(scripts/profile-multiworld.sh,StandardOutput=append: + exec 2>&1,state.json 记
pid/unit/log/commit/参数/起止/exit)。主运行 wall=1024.4s(17.1min < 40min),exit=0。
结论(artifacts/perf-multiworld/20260928T195839Z/README.md):
- 随世界数近似线性,未超线性:N=1 vs N=10(同日 D=20)annals/memory_entries 恰 10×、
rumors 9.67×、gc_live 8.81×(每世界 1.23MB,共享运行时开销摊薄)。
- RSS 有界无泄漏:N=10 39→峰值123(day8)→稳定104~112MB;每 2 天一轮墙钟恒 101~105s。
原因是历史集合有界(rumorRetentionDays=3 / rumorCapacity=16384 / maxAnnalEntries=128 /
Mind.Memory 上限),约 day4 后进入稳态。
- 两轮世界0 digest 一致(2364CB74…)→ 并存+并行不改变单世界语义。
- 数字未越界 → 明确「不修」;只读本 slice 不修 Kernel/Sim。
回归:Desktop 304/304 + Kernel 119/119;--performance-baseline ×3 digest
953775FAEB2F… 不变,performance_determinism=PASS。未 push。
