Struct ContextAssembler 

pub struct ContextAssembler { /* private fields */ }

Assembler for deterministic context construction per CP-021.

Implementations

impl ContextAssembler

pub fn new(budget: TokenBudget) -> Self

pub fn with_budget(total_tokens: usize) -> Self

Create with a simple token budget.

pub fn assemble( &self, chunks: Vec<ScoredChunk>, query: &str, state_root: [u8; 32], ) -> AssembledContext

Assemble chunks into a deterministic, byte-identical context.

Per CP-021 §11:

1. Deduplicate by chunk ID and text hash (80% overlap threshold)
2. Sort deterministically: score desc → doc path asc → seq asc → byte_offset asc
3. Group by document
4. Greedy pack within budget
5. Format with [DOC: path] markers

pub fn format(context: &AssembledContext) -> String

Format the assembled context as a string with [DOC: path] markers.

Per CP-021 §9.
