这道 Gate 还没开评审会，为什么已经是黄的？This gate hasn’t been reviewed yet.Why is it already yellow?

最差 = 七项健康里最差的（红 > 黄 > 其它）
如果 这是当前 Gate 且 最差 是红或黄：
    显示 最差，并注明由哪几项推得
否则：
    显示 评审结论（包括手改）

worst = the worst of the seven health checks (red > yellow > anything else)
if this is the current gate and worst is red or yellow:
    show worst, and name the checks it came from
else:
    show the review verdict (manual verdicts included)

可以确认 = 选的颜色 ≠ 当前评审结论
         且（原因去掉空白后不为空 或 这是首次设定）
首次设定 = 这道 Gate 在变更链里还没有记录，且当前是未评审
原因 ≤ 100 字（按字素计，一个 emoji 算 1 个）
确认 = 滑块拖到 100%；中途松手弹回，双击不会触发
写入 = 这道 Gate 的手改结论 + 变更链头部一条（第几次、从什么到什么、谁、精确到秒）

can confirm = the picked colour ≠ the current verdict
              and (the trimmed reason is not empty or this is a first setting)
first setting = the gate has no entry in the chain yet and is not reviewed
reason ≤ 100 characters (graphemes: one emoji counts as 1)
confirm = slide to 100%; letting go early springs back, a double-click does nothing
write = the gate’s manual verdict + one entry at the head of the chain (which change, from, to, who, to the second)

格子状态
  不需提交的格                      → 不需提交
  池 = 按关键件 且 有关键件 ? 关键件 : 全部件
  N = 池的条数，M = 其中交了的条数
  N = 0                            → 待定条目（0/0 不算交齐）
  M ≥ N                            → 交齐
  M > 0                            → 2M ≥ N ? 过半 : 不到一半
  这道 Gate 已通过                  → 已通过 · 不再催
  最早的期限 < 今天                 → 逾期
  最早的期限 = 今天                 → 今日到期（当天不算逾期）
  其余                             → 未到

催办（蚂蚁线）
  项目暂停 / 完成 / 归档，或 Gate 已通过 → 不催
  每条「有负责人、没交、有期限」的条目：
    有没处理的「期限赶不上 / 这项不适用」反馈 → 跳过（暂停催办）
    期限 − 今天 ≤ 1 → 催；期限 < 今天 → 逾期（红），否则即将到期（蓝）
  项目经理点「已阅」= 反馈处理完，恢复催办

Cell state
  cell not required                → not required
  pool = critical basis and any critical file ? critical files : all files
  N = files in the pool, M = delivered among them
  N = 0                            → to define (0/0 is not complete)
  M ≥ N                            → complete
  M > 0                            → 2M ≥ N ? over half : under half
  gate already passed              → passed · no reminders
  earliest due < today             → overdue
  earliest due = today             → due today (the due day is not overdue)
  otherwise                        → not yet

Reminders (marching ants)
  program on hold / closed / archived, or gate passed → none
  for each file with an owner, not delivered, with a due date:
    unread “can’t make the date / not applicable” feedback → skip (paused)
    due − today ≤ 1 → remind; due < today → overdue (red), else due soon (blue)
  the PM marks the feedback as read → reminders resume

端点 = 锚点日期 + 偏移天数            锚点：OTS / PPAP / SOP
锚点没有日期 → 这一行不画，列进「缺数据源」
拖整条 → 两端偏移一起 +d；拖手柄 → 只改这一端
结束 − 开始 ≥ 1 天（拖手柄时夹住）
被拖的端点离相邻行端点 ≤ 3 天 → 接上去；接上会破坏「≥ 1 天」就不接
OTS ∈ [−30, PPAP − 90]   PPAP ∈ [OTS + 90, SOP − 60]   SOP ∈ [PPAP + 60, PPAP + 460]

end = anchor date + offset in days       anchors: OTS / PPAP / SOP
anchor has no date → the row is not drawn; it is listed under "Missing source"
drag the bar → both offsets + d; drag a handle → that end only
end − start ≥ 1 day (handles are clamped)
dragged end within 3 days of a neighbour's end → snap to it, unless that breaks "≥ 1 day"
OTS ∈ [−30, PPAP − 90]   PPAP ∈ [OTS + 90, SOP − 60]   SOP ∈ [PPAP + 60, PPAP + 460]

行       = 未归档的完整项目（现算）+ 轻量行（自带结论）
当前评级 = 完整项目走决策 ① 的勾连规则，和别处同一份

rows    = unarchived full programs (derived live) + light rows (carry their own verdict)
rating  = full programs use the Decision 1 link rule, the same one used everywhere
overdue file cells = the Decision 3 matrix rule, on the real today
filter  = status AND preset
outer   = count by status
inner   = active only, split by current rating; placeholders elsewhere
bars    = programs sitting at each gate, stacked by current rating
banner  = compare aggregate(demo seed) with aggregate(now)
