Enum ProjectionRole 

pub enum ProjectionRole {
    Filterable,
    Rankable,
    Searchable,
}

0.8.20 Slice 15d (R-20-PR, C-1) — one member of a ProjectionSpec’s role set. Exactly three members (HITL-ratified S8, api-surface.md:87): searchable→FTS and searchable→vector are NOT roles — they are tier labels carried by the fts/vector sub-objects of the spec, so an attribute is Searchable once and the sub-objects select FTS-only / vector-only / both.

Variants

Filterable

Projects into the EAV store + its (attr_name, attr_value) composite index — cheap equality/range, built same-transaction.

Rankable

The F9 importance/recency signal. Graceful-absent (Q6a): declaring it is legal and never errors, but the engine DEFERS the build until F9 exists and grafts it on the next idempotent configure_projections.

Searchable

Full-text / dense recall of the meaning text. The fts/vector sub-objects select the sub-target.
