! # !! Name !! Meaning
|-
| 1 || layer / kind || <code>0</code> → ground tree, <code>≠0</code> → air tree. In practice always ≥ 1 (no row is 0), so every row goes to the air tree — the gated-off path.
|-
| 2 || week || in-game week (1-based). <code>99</code> = recurring/any week — selects a separate keyframe layout.
|-
| 3 || day || in-game day (1-based).
|-
| 4 || hour || 0–23.
|-
| 5 || minute || 0–59.
|-
| 6 || second || 0–59.
|-
| 7 || aux param A || effect payload; only used when week ≠ 99 (one-shot events).
|-
| 8 || aux param B || effect payload.
|-
| 9 || keyframe_count || <code>Effect_Def.keyframe_count</code> (struct off 40).
|-
| 10 || keyframe_start || <code>Effect_Def.keyframe_start</code> (struct off 44).
|-
| 11 || keyframe_end || <code>Effect_Def.keyframe_end</code> (struct off 48).
|-
| 12 || target id || object/node/zone the action runs on: <code>&lt; 10000</code> → world object; <code>&gt;= 10001</code> → map-area node = <code>world.wlist</code> record <code>id − 10001</code>; <code>11190</code> → zone. If <code>&lt; 10000</code> it's decremented to a 0-based index. (struct off 56)
|-
| 13 || mode / action || which <code>Event_Dispatch</code> action runs (state change / sound / lighting+transition). Values 0, 1, 3 get special count handling (col 14). (struct off 60)
|-
| 14 || count / repeat || if <code>mode∈{1,3}</code> and <code>≠99</code> → <code>−1</code>; if <code>mode==0</code> and <code>==0</code> → <code>−1</code>. <code>99</code> kept as "infinite/any". (struct off 64)
|-
| 15 || aux param C || action payload (e.g. sound id / state value). (struct off 68)
|-
| 16 || aux param D || action payload. (struct off 52)

Cols 9/10/11/13/14 map to named <code>Effect_Def</code> fields and col 12 is the dispatch target id. Cols 7/8/15/16 land in currently-unnamed <code>Effect_Def</code> offsets (32/36/52/68) and carry the per-action payload — treat these column-to-payload bindings as provisional.
