price meter.
oracle/proposers -> plan.json <-> [editor UIs] -> backend -> graph -> queue_scene
Layering, and it is load-bearing:
timeline/schema.py SEMANTIC INTENT ONLY. Stdlib. No H3, no torch.
timeline/backend.py the four-method seam (capabilities/validate/
compile/estimate). One implementation, no factory.
timeline/price.py geometry x complexity model x machine calibration,
three separable factors.
timeline/recorder.py the flight recorder that calibrates layer (b).
timeline/h3/ EVERYTHING H3-specific: model spec (structural,
relied on), recipe profile (experiment-derived,
challengeable, cited), grid law, compiler, oracle
proposer.
timeline/nodes.py thin ComfyUI clients. No rules live here.
A UI is a viewer/editor of the plan and never contains legality math.
Adding a capability means adding a lane type, not a node pack.
NOTE: this file imports NOTHING on purpose. `timeline.schema` must be
importable with no torch, no comfy and no h3 in the process (the test
suite asserts exactly that in a subprocess), so the ComfyUI node
registrations live in timeline/nodes.py and the pack's __init__ imports
that submodule directly.
