Deterministic assembly plans for named inputs and reproducible build receipts.

sheaffoundry

sheaffoundry models a small, reviewable assembly plan. A plan names its inputs, orders assembly steps, and emits a deterministic receipt suitable for logs, test fixtures, or provenance records.

from sheaffoundry import AssemblyPlan, Input, Step

plan = AssemblyPlan(
    "preview-image",
    inputs=(Input("source", "sha256:abc"), Input("palette", "v3")),
    steps=(Step("decode"), Step("render", needs=("decode",))),
)

receipt = plan.receipt()
assert receipt.step_order == ("decode", "render")

Steps form a directed acyclic graph. The package validates missing dependencies and cycles, then uses lexical tie-breaking to produce a stable execution order. There are no runtime dependencies.
