Seven production pipeline utility nodes for ComfyUI: - PD Project Context: top-level metadata/token source - PD Shot Token: lightweight template string resolver - PD Output Namer: structured output filename builder - PD Network Output: image writer with UNC path support - PD Switch: multi-channel wildcard input router (up to 8×8) - PD Wedge: iteration node with optional auto-queue injection - PD Rasterizer: dry-run wedge cartesian product previewer Core infrastructure: - core/compat.py: legacy + Nodes 2.0 (V3) API compatibility shim - core/tokens.py: standalone token resolution engine - core/utils.py: path normalization and directory helpers - web/pipedream_rasterizer.js: minimal JS for rasterizer preview https://claude.ai/code/session_015UV4rjSvFatMiNtKhd1sT3
