"""Server-side WhaleTown V2 skin generation runner.

The NestJS skin generation service owns the API key and calls this script as a

worker. Novamailio generates three canonical poses for front/back and eight

frames for side views. The worker expands canonical poses deterministically,

uses the cutout tool, then assembles a transparent 8x4 spritesheet.

Its shoe becomes slightly larger/wider because of perspective, but its ankle and shoe center remain directly below the screen-left hip. The screen-right leg stays neutral below the screen-right hip. Do not move either foot sideways. Do not force either shoe lower; preserve Image 2's actual vertical positions.

Its shoe becomes slightly larger/wider because of perspective, but its ankle and shoe center remain directly below the screen-right hip. Do not move either foot sideways. Do not copy column 2's screen-left-leg action into this column. Do not force either shoe lower; preserve Image 2's actual vertical positions.

|
|
- Mandatory screen-space sequence from column 1 through 8: NONE, LEFT, NONE, RIGHT, NONE, LEFT, NONE, RIGHT.

After drawing columns 1-4, duplicate their pose geometry into columns 5-8: column 5 pose = column 1 pose, column 6 pose = column 2 pose, column 7 pose = column 3 pose, and column 8 pose = column 4 pose. Only tiny rendering variation is acceptable; the active leg, ankle location, shoe size, shoe spacing, and outer silhouette must repeat.
|
|
- Here LEFT and RIGHT name the active leg only. They never mean that a foot travels toward the left or right edge of the cell.
|
|
- Lateral spacing lock: keep the two ankles almost as close together as in neutral columns. In the final 160x160 frame, an active shoe center may shift horizontally no more than about 3 px from that same leg's neutral shoe center. Do not splay the legs, make a V stance, or increase the gap between the feet.
|
|
- Perspective test: the active motion must read as one foot coming toward the camera through foreshortening and visible shoe-top/sole shape, while the legs remain narrow and nearly vertical.
|
|
- A result where the feet step outward to screen-left or screen-right is invalid, even if the correct leg alternates.

Task:
|

Create the {direction.upper()} row of an 8-frame WhaleTown walking spritesheet.
|
|
|
|
Inputs:
|
|
- Image 1 is an appearance-only identity master. Preserve its character design, but ignore all of its poses, leg positions, shoe positions, stance, and animation frames.
|
|
- Image 2 is already cropped to the official WhaleTown {reference_row} motion reference row for this task.
|
|
|
|
Hard rule:
|
|
- This is animation/direction conversion only. Do not reinterpret the uploaded character reference. Do not redesign the character.
|
|
- Preserve the identity master's recognizable character traits as they should appear from the requested viewing direction: hair/head silhouette, outfit, color placement, proportions, outline style, and rendering style.
|
|
- Change only the viewing direction and the walking pose for this row.
|
|
- Direction lock: {DIRECTION_LOCKS[direction]}
|
|
- Image 1 identity lock: keep Image 1's hair color, hairstyle or head silhouette, outfit structure, outfit colors, skin tone, and overall character design in all 8 columns.
|
|
- Image 1 must never control pose. Do not preserve its standing legs or feet.
|
|
- If the identity master has no hat or hood, do not add any hat, hood, cap, helmet, animal ears, hair accessory, or new head accessory in any direction.
|
|
- Do not copy Image 2's character identity. Image 2 is only a pose/feet template.
|
|
|
|
Output layout:
|
|
- Exactly 8 equal columns x 1 row on a flat pure magenta #FF00FF background.
|
|
- No text, no labels, no dividers, no UI, no watermark, no props, no shadows.
|
|
- Each assembled frame will be 160x160 px.
|
|
|
|
Size target for this {direction.upper()} row:
|
|
- Visible character alpha box height: {spec["body_height"]} px.
|
|
- Visible character alpha box width: {spec["body_width"]} px, acceptable range {spec["body_width_range"]}.
|
|
- Character bottom/foot baseline: y={spec["foot_y"]} px.
|
|
- Direction-specific note: {spec["description"]}.
|
|
|
|
Motion reference:
|
|
- Authority split: Image 1 controls identity, outfit colors, hair, and rendering style. Image 2 controls pose, walking rhythm, lower-body silhouette, foot side, shoe spacing, stride size, and foot baseline.
|
|
- Pose priority is absolute: whenever identity preservation conflicts with pose matching, preserve Image 1's appearance but use Image 2's pose and body-part positions.
|
|
- Treat Image 2 as a strict pose template for this row, not a loose style reference.
|
|
- For every column, first reproduce the complete corresponding Image 2 body pose and lower-body silhouette, then apply Image 1's character appearance onto that pose.
|
|
- Match the positions and silhouettes of both legs, both ankles, and both shoes from the corresponding Image 2 column.
|
|
- Copy only the pose geometry from Image 2. Ignore Image 2's character design completely.
|
|
- {FOOT_TEMPLATE_LOCKS[direction]}
|
|
- The foot baseline, stepping side, toe direction, shoe spacing, stride size, and neutral-vs-step rhythm must match Image 2 column by column.
|
|
- Do not average the walking cycle into eight standing frames. Columns 2, 4, 6, and 8 must show visible foot displacement compared with columns 1, 3, 5, and 7.
|
|
- Changing only shoe color, sole color, lighting, shading, texture, or line details does not count as movement.
|
|
- In every active step frame, at least one shoe outline must visibly move in position relative to the neutral frame, and the leg silhouette must change with it.
|
|
- Silhouette test: if all colors and internal details were removed, the stepping action must still be obvious from the outer leg-and-shoe silhouette alone.
|
|
- If a step column looks like a neutral standing column, the result is invalid.
|
|
- If the feet do not match Image 2's column-by-column action, the result is invalid even if the character identity looks good.
|
|
- Do not copy the reference character identity.

- Image 1 is appearance identity only. Preserve its hair, face or back-head design, outfit, colors, proportions, outline, and rendering style. Ignore every pose and foot position in Image 1.
|
|
- Image 2 is the official WhaleTown {reference_row} 8-frame motion row. Use pose geometry from Image 2 columns {source_columns}: neutral pose, first-leg action, opposite-leg action.
|

|
Output layout:

- Exactly 3 equal columns x 1 row, ordered A, B, C from left to right.

Identity and direction locks:

|
|
- Keep Image 1's exact character identity in all three columns.
|
|
- If Image 1 has no hat or hood, do not add one.
|
|
|
|
Size consistency:
|
|
- All three characters must have the same head size, shoulder width, body height, clothing size, centerline, and baseline.
|
|
- Target assembled character height is {spec["body_height"]} px, width about {spec["body_width"]} px, and foot baseline y={spec["foot_y"]} px in a 160x160 frame.
|
|
- Only legs and shoes may change between A, B, and C.
|
|
|
|
Canonical poses:
|
|
{POSE_TRIPLET_ACTIONS[direction]}
|
|
|
|
Hard comparison rules:
|
|
- B and C must use opposite legs. They must not show the same active leg.
|
|
- Pose C must not be a duplicate of pose B.
|
|
- Both feet must remain visible in every pose, including the grounded shoe and the lifted/forward shoe.
|
|
- Match Image 2's compact stride. Do not widen the stance or move a foot toward a cell edge.
|
|
- The active leg must be recognizable from the outer silhouette, not only from color, shading, or sole details.
|
|
- The result is invalid if B and C move the same screen-side leg.

Create one single canonical {direction.upper()} pose for a WhaleTown walking animation.

Inputs:

- Image 1 is appearance identity only. Preserve its hair, face or back-head design, outfit, colors, proportions, outline, and rendering style. Ignore all poses in Image 1.

|
|
|
|
Output:
|
|
- Exactly ONE full-body character on the entire canvas. Do not create a row, sequence, comparison, duplicate, or additional character.
|

- Center the character on a flat pure magenta #FF00FF background.

|
|
|
|
Required pose:
|
|
- {action}
|
|
- {DIRECTION_LOCKS[direction]}
|
|
- Keep the head, hair, shoulders, torso, hips, and both arms in a perfectly neutral upright standing pose. Both arms hang straight down at the sides. Do not swing or bend an arm, rotate the torso, lean the body, or create a running pose.
|
|
- Only the active leg and shoe may differ from a neutral standing pose. The motion must remain compact enough for a calm game walk cycle.
|
|
- Both feet must remain visible: one active foot and one grounded/neutral foot where applicable.
|
|
- Match Image 2's compact stride and actual leg/shoe geometry. Do not widen the stance or move a foot toward a canvas edge.
|
|
- The active leg must be recognizable from the outer silhouette, not only from color or shading.
|
|
|
|
Identity locks:
|
|
- Image 1 controls identity and all neutral upper-body geometry; Image 2 controls the requested leg and shoe pose only.
|
|
- Preserve every existing non-leg feature from Image 1: head silhouette, hairstyle or headwear, facial or back-head details, upper-body proportions, outfit silhouette and garment geometry, shoulders, torso, arms, hands, accessories, outline thickness, colors, and rendering details. Do not redesign, add, remove, or reinterpret those features.
|
|
- For an active pose, redraw only the active leg and shoe as required. Keep the grounded leg as close to Image 1 as possible.
|
|
- Lower-body appearance is locked to Image 1. Preserve the exact trousers, socks, shoes, soles, trims, color blocks, materials, and outline colors from Image 1 on both legs. Change their geometry only as needed for the requested pose.
|
|
- Image 2 contributes no appearance information. Do not sample, blend, transfer, or invent any lower-body color or clothing detail from Image 2. A changed shoe, sock, trouser color, trim, or material makes the output invalid.
|
|
- The grounded leg and grounded shoe must remain visually identical to Image 1 apart from unavoidable overlap by the moving leg.
|
|
- When an edit mask is supplied, change pixels only inside its transparent lower-body region. Pixels outside that region must remain exactly unchanged.
|
|
- Never copy Image 2's hair, face, hood, clothing, colors, accessories, or identity.
|
|
- If Image 1 has no hat or hood, do not add one.
