用户反馈: 黄灯常亮故障补偿后, 金属板进入触发的高度比断电上电后低很多, 补偿结束也恢复不了正常灵敏度。
根因(两处, 均可复核): V4B 进入判定用 vac_ref()=min(Origin, 真空EMA) 而非 Origin (TaskLoop.c:1432)
① env_resync_apply() 只原子换 loop1_Origin, 没同步 g_vacuum_ema。补偿前提是 dev>+4×dlt 连续 7s,
学到的 B≈当前 CAPVD ⇒ Δ≥4×dlt 必然 ⇒ Origin−EMA=Δ>1×dlt ⇒ vac_ref 必然切旧 EMA ⇒ 进入线整整低 Δ
② g_vacuum_ema += _ema_d/128 为整数除法, |d|<128 时步进恒 0 ⇒ EMA 粘在真空下方 ≤127 counts
(2.59×dlt > 1×dlt 门槛) ⇒ 进入线常驻偏低 ≈0.100% Δf/f 且不自愈; 断电上电 EMA=Origin(偏差 0) 故持久正常
修复:
- 新增 origin_set_atomic() (TaskLoop.c:308): "一步换 Origin"时 |ΔOrigin| > ORIGIN_JUMP_REANCH_DLT(=1)×dlt
则同步重锚 g_vacuum_ema; 与 VAC_REF_DELTA_DLT 同口径 ⇒ 维持 |Origin−EMA| ≤ 1×dlt 不变式; 小步不动 EMA
- 3 处 Origin 写入点改经它: env_resync_apply(:968) / 重连判稳完成(:1207) / 冻结超时更新(:1372)
- EMA 更新改余数累加器 g_vac_frac(:1344) 消 ±127 counts 死区; g_vac_frac 在 INIT(:583)/判稳(:1266) 清零
单测(新增 tests/test_vac_ref_reanchor.c, 5 场景; gcc -O0 -Wall -Wextra 0 warning; 全套 8/8 全绿):
补偿后进入线 130457(低 130 counts = 2.65×dlt = 0.100% Δf/f) → 130587(低 0); EMA 追赶偏差 127→0 counts
