Module node 

Canonical procedural seed nodes (Phase 11, ADR-0025).

A SeedNode describes one computation, not one storage slot: a bounded, versioned materializer over zero or more dependencies, producing a declared output kind and logical length. Nodes are canonically encoded (little-endian, length-prefixed, no serde) so that the same computation always hashes to the same NodeId regardless of platform or insertion order.

The node’s content_id is not stored inside the node: it is NodeId::of_node(canonical_bytes), which is what makes the graph content-addressed and immutable. Changing a dependency’s bytes yields a different dependency id, hence a different node id; there is no mutation.

Structs

NodeLimits

A bounded resource envelope declared by a node.

SeedNode

One canonical procedural seed node.

Enums

NodeKind

What a node computes. The numeric values are part of the canonical encoding.

Constants

MATERIALIZER_VERSION

The materializer semantics version for v1.

MAX_NODE_BYTES

Recommended maximum canonical node size (framing discipline).

MAX_NODE_DEPS

Maximum dependency fanout of a single node.

NODE_MAGIC

Canonical header byte for the node encoding.

Functions

object_params

Encode a (u32, u16, ...) object-identity parameter block: object, generation, then a trailing kind-specific u64.

read_object_params

Decode an object-identity parameter block.

read_span_params

Decode an [offset, len] parameter block.

read_u32_params

Decode a single u32 parameter.

span_params

Encode an [offset, len] parameter block.

u32_params

Encode a single u32 parameter.
