# Evidence Context Budget Pack

Build-time release reference. Runtime readiness, deployment, payment settlement and external indexing are not evaluated here. Prices are proposed; this file cannot authorize execution or payment.

Greedily select exact source spans by required status, priority and stable ID within caller-supplied integer cost units. Keeps provenance, rejects broken spans, protects required candidates and deduplicates optional identical text. Does not tokenize, summarize, infer semantic relevance, or guarantee an optimal packing.

Release: 0.29.0. Built: 2026-10-06T15:38:00Z.

## Choose for
- Pack RAG evidence spans into a caller-defined context budget
- Keep mandatory excerpts while removing duplicate optional context

## Outside this profile
- Tokenizer-accurate model limits or semantic retrieval
- Optimal knapsack solutions or verifying caller-provided cost estimates

Proposed nominal USD 0.005 per successful call; payer fees excluded. No verified runtime availability.
