Reads the to-build derivation DAG from Nix (derivation show -r + --dry-run), applies a heuristic/history build-cost model with Amdahl core-scaling, and computes critical-path / peak-concurrency / list-scheduled makespan across a node×core grid to recommend a remote-builder shape. - schedule.py: pure critical-path, peak-concurrency, p-machine list scheduler - costmodel.py: heuristic table + --history override + core re-weighting - graph.py: DAG extraction via nix - estimate.py/cli.py: sweep + knee recommendation + report - tests: scheduler validated on toy DAGs (all pass) Prior-art gap documented (Hubble, nixbuild.net) in README.
