Per-frame GT object prefill

Each one-frame detector request was assistant-prefilled with the exact visible GT objects using canonical IDs. B1 generated only the interaction suffix; the saved frame outputs below are the exact persisted requests and generations.

Prompt
<video>
Analyze the provided video and return ONLY a valid sentinel sequence in this format:
[SCENE-START] [OBJS-START]
[OBJ] id "type" birth death [PX] t px py ...
[OBJ] ...
[OBJS-END]
[INTERACTIONS-START]
[INTERACT] id "type" begins_at ends_at [IN] in0 in1 ... [OUT] out0 out1 ...
[INTERACT] ...
[INTERACTIONS-END] [SCENE-END]

Constraints:
- Return only the sentinel text (no JSON, XML, markdown, comments, or extra prose).
- Keep tags exactly as written:
  `[SCENE-START] [OBJS-START] [OBJ] [PX] [OBJS-END] [INTERACTIONS-START] [INTERACT] [IN] [OUT] [INTERACTIONS-END] [SCENE-END]`
- Use quoted strings for `type` (double quotes).
- `PX` uses repeated groups of 3 values in order: `t px py`.
  - `t` is the timestamp (frame number).
  - `px` and `py` are the pixel coordinates of the object in that frame, normalized to [0,1] relative to the frame dimensions, scaled by 1000 and rounded to the nearest integer. For example, `px` of 0.1234 would be represented as 123.
- When an object is occluded or not visible in a frame, `PX` may use `t null null`.
- `IN` and `OUT` contain whitespace-separated integer ids.
Baseline 2

B1 cache + injected GT identity map

B2 consumed the persisted B1-oracle frame cache. Its learned mapper call was bypassed at every streaming step and replaced with the shown stable-ID → detector-ID identity map; the ordinary staged merger still produced the final interaction prediction.

Baseline 3

Growing GT object-track prefill

At prefix step t, B3 saw frames 0..t and an assistant prefill containing GT object tracks only through t. The prefills are deterministically reconstructed with the exact oracle helper; only the final full-clip generation was persisted by inference.

Prompt
<video>
Analyze the provided video and return ONLY a valid sentinel sequence in this format:
[SCENE-START] [OBJS-START]
[OBJ] id "type" birth death [PX] t px py ...
[OBJ] ...
[OBJS-END]
[INTERACTIONS-START]
[INTERACT] id "type" begins_at ends_at [IN] in0 in1 ... [OUT] out0 out1 ...
[INTERACT] ...
[INTERACTIONS-END] [SCENE-END]

Constraints:
- Return only the sentinel text (no JSON, XML, markdown, comments, or extra prose).
- Keep tags exactly as written:
  `[SCENE-START] [OBJS-START] [OBJ] [PX] [OBJS-END] [INTERACTIONS-START] [INTERACT] [IN] [OUT] [INTERACTIONS-END] [SCENE-END]`
- Use quoted strings for `type` (double quotes).
- `PX` uses repeated groups of 3 values in order: `t px py`.
  - `t` is the timestamp (frame number).
  - `px` and `py` are the pixel coordinates of the object in that frame, normalized to [0,1] relative to the frame dimensions, scaled by 1000 and rounded to the nearest integer. For example, `px` of 0.1234 would be represented as 123.
- When an object is occluded or not visible in a frame, `PX` may use `t null null`.
- `IN` and `OUT` contain whitespace-separated integer ids.

One full-clip GT object prefill

The E2E model saw all 24 frames once. Its assistant text was the exact GT object section through [INTERACTIONS-START], and the model generated only the interaction suffix shown here.

Analyze the provided video and return ONLY a valid sentinel sequence in this format:
[SCENE-START] [OBJS-START]
[OBJ] id "type" birth death [PX] t px py ...
[OBJ] ...
[OBJS-END]
[INTERACTIONS-START]
[INTERACT] id "type" begins_at ends_at [IN] in0 in1 ... [OUT] out0 out1 ...
[INTERACT] ...
[INTERACTIONS-END] [SCENE-END]

Constraints:
- Return only the sentinel text (no JSON, XML, markdown, comments, or extra prose).
- Keep tags exactly as written:
  `[SCENE-START] [OBJS-START] [OBJ] [PX] [OBJS-END] [INTERACTIONS-START] [INTERACT] [IN] [OUT] [INTERACTIONS-END] [SCENE-END]`
- Use quoted strings for `type` (double quotes).
- `PX` uses repeated groups of 3 values in order: `t px py`.
  - `t` is the timestamp (frame number).
  - `px` and `py` are the pixel coordinates of the object in that frame, normalized to [0,1] relative to the frame dimensions, scaled by 1000 and rounded to the nearest integer. For example, `px` of 0.1234 would be represented as 123.
- When an object is occluded or not visible in a frame, `PX` may use `t null null`.
- `IN` and `OUT` contain whitespace-separated integer ids.
