Appendix G The part table’s fields, at a glance

work/<name>/parts.py, an ordinary Python module; a missing field is a hard error (config.REQUIRED). The template is dtp/templates/project/parts.py — copy it into the subproject.

field	which stages it governs	format	how to write it	change it, rerun from
`ASSIGN`	segment (1); the one-shot route uses only this one; with the lines as walls (`ASSIGN_FROM`) it inherits the previous step’s	`[("sub-part", [region number, …]), …]`	written against the `regions.png` of the first `segment`; the order is the occlusion order, bottom -> top	all of it, from `segment`
`ORDER`	segment, and the one-shot route’s tree	`[n for n, _ in ASSIGN]`	never edited	—
`CLASSES`	the majority vote in segment	`[("class", ["word", …], ["sub-part", …]), …]`	the order is the priority: small and specific first	from `segment`
`SAM_WORDS`	segment	`["hair", "red bow", …]`	the more specific the word the better; a word whose mask covers more than 40% of the subject is useless	from `segment`
`KEEP_ASSIGN_REGION`	segment	`["sub-part", …]`	the sub-parts that skip the vote and keep the whole region the hand-written table gave them	from `segment`
`GROUPS`	complete (3), per-layer lineart, draft (5), paint	`[("group", ["sub-part", ...]), ...]`	a group is one layer, the union of its sub-parts; the order is the occlusion order, which is the order of the groups in the `.kra`. Written by looking at the region image and the lineart image	from `complete`
`SHARED_FLAT_COLOR`	draft (5)	`{"group": "shared name", …}`	the groups that share one local colour	from `draft`
`GROUPS_FROM_MASK`	per-layer lineart (4), draft (5)	`[("group", "mask_x.png", "after which group", "the sub-part it depends on")]`	a layer split out of another group with an AI mask	from `lines`
`LINES`	lineart (2)	`[("Line_X", ["sub-part", …]), …]`	the lineart layers; every sub-part belongs to exactly one of them	from `lineart`
`LINE_LAYER_OF_GROUP`	per-layer lineart (4)	`{"group": "Line_X", …}`	which lineart layer each layer’s lines go to, the `GROUPS_FROM_MASK` groups included; a group that is not listed gets no lines	from `lines`
`STRAND_GROUPS`	paint (6), one-shot	`{"group", …}`	the groups that grow strands. Empty in the template; the one-shot route also needs `strands=True`	`paint` / `trace`
`HATCH_GROUPS`	one-shot (8)	`{"sub-part", …}`	the sub-parts that get hatching. Empty in the template; the one-shot route also needs `hatch=True`	`trace`
`SEETHROUGH`	complete (3)	`{"group": ["its layers", …], …}`	which See-through layers each group takes as candidates for its whole shape (only the occluded part is used); a group that is not listed only gets its seam filled; the layer names are in the template’s comments	from `complete`
`LINE_DROP_BY_LAYER`	paint (6)	`{"Line_X": 6.0, …}`	one lineart layer’s own threshold: a line that is not darker than its surroundings by at least this much is not painted; a layer that is not listed uses the `line_drop` knob of the paint step	`paint`
`PAINT`	paint (6)	`{"group": dict(method=..., ...), "*": dict(method="generic")}`	which method paints each group (`method` is a name in `dtp.paint.METHODS`, one page per body part: `shadow_tier` skin - `eye` eyes - `hair` hair - `generic` the baseline “copy” - eight placeholders) and its knobs; `"*"` is mandatory; a misspelled name fails the part table, and a group that picked a placeholder raises “not decided yet” at paint time	`paint`
`CROPS`	review (7)	`{"face": (x, y), "neck": …, …}`	the centres of the 1:1 close-ups, in 8x coordinates; at least the face, the neck, the hands and the feet	the next painting run
