Struct DocId 

pub struct DocId(pub u64);

Canonical document identity consumed by the fusion kernel.

A newtype (rather than a bare u64) so a retrieval-space document id can never be silently confused with a raw vector offset, record id, or rank. The fusion kernel keys exclusively on this type; executors convert their native ids into a DocId at the boundary.

Identity-space contract (Task 1)

DocId is the retrieval-universe identity, a dense u64 shared by every lane that participates in pre-filtered fusion:

Lane	Native key	Relationship to DocId
BM25 / inverted index	u64 doc id	identical (DocId(id))
Grep / trigram lane	DocId = u64 alias	identical
AllowedSet membership	u64	identical (AllowedSet::contains(d.get()))
HNSW vector graph	u128 storage id	mapped at the boundary

The first three are the same key space, so an AllowedSet produced by one lane gates every other lane with an O(1) membership test on DocId.0. The HNSW graph keys on a wider u128 storage id; the vector executor narrows that to a retrieval DocId when it emits candidates (and accepts an allowed(u128) predicate over the same mapping — see HnswIndex::search_allowed). Threading the newtype down into the u128 storage layer is deliberately out of scope here: it touches the durable id space and yields no behavioral change while this kernel keys on DocId.

impl Ord for DocId

fn cmp(&self, other: &DocId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool
