Delivery blueprint

Long context where retrieval is only the first move.

Original document worlds that require models to find distributed evidence, join claims across files, resolve time and entity ambiguity, calculate derived answers, and cite exactly what supports the result.

Needles are not enough; the answer must be constructed.

The target is reasoning over long, heterogeneous document sets: locate several relevant facts, determine how they relate, handle conflicts and dates, compute or synthesize the answer, and preserve a verifiable evidence chain.

Yotta Content can build original or permissioned document worlds around company reports, legal files, government consultations, academic literature, industry research, policy materials, surveys, or a client's own enterprise corpus. Questions are designed so no single sentence states the answer.

Document worlds are versioned like environments.

Corpus

Immutable document set

Files, extracted text, layout references, checksums, permissions, dates, and document-level metadata.

Question

Distributed evidence

The answer requires a join, comparison, calculation, temporal resolution, or synthesis across multiple locations.

Evidence graph

Claim provenance

Gold evidence nodes, supporting spans, transformations, intermediate claims, and contradiction relationships.

Adversarial context

Realistic distractors

Near-matching entities, stale periods, repeated tables, conflicting versions, decoy numbers, and irrelevant documents.

Answer equivalence and evidence faithfulness are separate.

LayerWhat it checks
Answer normalizationExact, numeric-tolerance, list, date, entity, or structured equivalence
Evidence recallWhether the cited spans include every necessary supporting fact
Evidence precisionWhether citations are specific and relevant rather than a context dump
Reasoning graphWhether intermediate joins, calculations, and temporal choices are valid
Contradiction handlingWhether newer, scoped, or authoritative evidence is selected correctly
Unsupported claimsWhether the response adds facts not entailed by the document set

The final task score can remain a strict pass/fail answer metric while evidence and reasoning components provide dense reward for post-training.

Trajectories reveal where long-context reasoning broke.

Evidence trajectoryRetrieval + synthesis
  1. Query plan: entities, dates, units, aliases, and candidate document types.
  2. Evidence events: document and span retrieval, table reads, discarded candidates, and contradiction flags.
  3. Reasoning state: normalized facts, cross-document joins, calculations, and provisional claims.
  4. Answer: response plus structured citations and confidence.
  5. Verifier: answer equivalence, evidence coverage, unsupported-claim labels, and earliest consequential failure.

From one failed attempt we can derive retrieval repairs, evidence-ranking pairs, contradiction examples, citation corrections, and end-to-end repaired trajectories.

What an AA-LCR-shaped program includes.

  • Permissioned, versioned document sets with layout-aware extraction, checksums, source metadata, and rights records.
  • Original questions requiring multi-document and multi-step reasoning rather than direct lookup.
  • Gold answers, evidence graphs, intermediate calculations, citations, acceptable variants, and ambiguity reviews.
  • Answer, evidence, contradiction, citation, and unsupported-claim graders with per-layer reward.
  • Retrieval and reasoning trajectories, failure labels, preference pairs, critiques, repairs, and private holdouts.

This is a proposed independent data program inspired by the long-context reasoning capability measured by AA-LCR. It is not Artificial Analysis data, a replica, an affiliation.
