A stream emission record — the materialized algebraic effect.

Fields

trace_id: u64

Execution/trace ID this token belongs to.

flow_name: String

Flow name being executed.

step_name: String

Step name that emitted this token.

token_index: u64

Sequential token index within this execution.

content: String

The emitted token/chunk content.

is_final: bool

Whether this is the final token (stream complete).

timestamp: u64

Unix timestamp.

epistemic_state: String

Epistemic state of this token in the lattice (⊥ ⊑ doubt ⊑ speculate ⊑ believe ⊑ know). Streaming tokens arrive as “speculate” — promoted to “know” only after anchor validation on the complete response.

effect_row: String

Effect row annotation: <effects, epistemic:level>. Declares what effects this token’s production involved. E.g., “<io, epistemic:speculate>” for LLM-generated content, “<pure, epistemic:know>” for validated results.

pix_ref: Option<String>

PIX index reference (if token from PIX navigation). Links to IRPix.name — the document tree being navigated.

corpus_ref: Option<String>

Corpus reference for MDN multi-document navigation. Links to IRCorpus.name — the document graph being traversed.

nav_trail: Option<Vec<String>>

Navigation trail — sequence of nodes visited during PIX tree traversal. Each entry is a node identifier from the document tree D = (N, E, ρ, κ). Implements the trail step from IRTrailStep.

mdn_edge_type: Option<String>

MDN edge type that led to this document (cite|depend|elaborate|contradict|…). From the MDN relation type taxonomy.

nav_depth: Option<u32>

Navigation depth in PIX tree or MDN graph at time of emission.
