# LLM Ambiguity Lab v2 > Free interactive SANA OS research and educational reference implementation for task resolution and premise alignment. Canonical: https://sana-os.org/llm-ambiguity-lab/ Primary language: English Version: 2.0 Creator and responsible maintainer: Deshimaru Sakaguchi ## Start here - [Interactive Lab](https://sana-os.org/llm-ambiguity-lab/): Human-facing two-layer simulator. - [README](https://sana-os.org/llm-ambiguity-lab/README.md): Canonical v2 overview and documentation map. - [Methodology](https://sana-os.org/llm-ambiguity-lab/methodology.md): Two-layer architecture, premise fields, alignment states, divergence, clarification, free-text heuristics, and handoff logic. - [Usage Guide](https://sana-os.org/llm-ambiguity-lab/usage.md): Six deterministic presets and interpretation guidance. - [Limitations](https://sana-os.org/llm-ambiguity-lab/limitations.md): Canonical scope and non-claims. - [Terms of Use](https://sana-os.org/llm-ambiguity-lab/terms.md): Public usage terms for v2. - [Citation](https://sana-os.org/llm-ambiguity-lab/CITATION.md): Preferred citation formats. ## Core architecture - Layer 1: DCRL Task Resolution asks, “What are we doing?” - Layer 2: SANA Premise Alignment asks, “What are we assuming while we do it?” - Layer 2 is deferred when Layer 1 returns `CLARIFICATION_REQUIRED` or `PENDING_SPECIFICATION`. - The public simulator does not execute the downstream task; it renders a premise-aware execution handoff. ## Critical interpretation rules - Premise Alignment is not Premise Agreement. - `FACT` is a functional factual-claim category, not `VERIFIED TRUE`. - A premise marked `inferred` is a simulator representation, not hidden-motive access. - The premise layer has no numeric confidence probability. - `support_state` is representational, not a calibrated truth score. - Meaningful divergence may remain explicit and attributed rather than being forced into consensus. ## Premise categories - `FACT`: proposition functioning as a factual claim. - `VIEW`: interpretation, evaluation, causal framing, judgment, or explanatory perspective. - `CARE`: concern, priority, protected interest, value, or outcome that matters within the task. ## Premise states - `MAPPED` - `MAPPED_WITH_DIVERGENCE` - `PREMISE_CLARIFICATION_REQUIRED` - `PREMISE_CONTEXT_INSUFFICIENT` ## Machine-readable specifications - [Premise Taxonomy](https://sana-os.org/llm-ambiguity-lab/data/premise-taxonomy.json): Fact/View/Care and premise-field vocabulary. - [Premise Alignment Policy](https://sana-os.org/llm-ambiguity-lab/data/premise-alignment-policy.json): Layer prerequisites, premise states, transition rules, divergence and clarification policy. - [Execution Handoff Schema](https://sana-os.org/llm-ambiguity-lab/data/execution-handoff-schema.json): JSON Schema for the public downstream handoff object. ## Related canonical resources - [SANA OS Framework](https://sana-os.org/system/): Human-facing framework page. - [SANA OS Framework Markdown](https://sana-os.org/system/index.md): Text-first framework explanation. - [LLM Ambiguity Lab v1](https://deshimarusakaguchi.com/llm-ambiguity-lab/): Standalone context-resolution predecessor. ## v2 boundary v2 does not automatically determine objective truth, infer hidden motives, reveal hidden model reasoning, guarantee downstream safety, or implement all SANA OS mechanisms. For those boundaries, prefer the canonical [Limitations](https://sana-os.org/llm-ambiguity-lab/limitations.md).
