-## Evidence
-
-### Behavioral correctness (key examples)
-
-Concrete behavioral comparisons (base model vs compiler) are available here:
-
-- [Open WebUI integration README](examples/integrations/openwebui/README.md)
-
-These demonstrate deterministic clarification, state enforcement, and conflict handling.
-
-### Cross-model evaluation
-
-- Models tested: `llama3.1:8b`, `gpt-4o-mini`, `gpt-4.1`, `gpt-5`, `claude-sonnet-4`, `claude-opus-4`
-- Pass-rate summary: baseline (LLM only) `2–4 / 6`; with compiler `6 / 6`; with compiler + compaction `6 / 6`.
-
-### Efficiency
-
-- Context reduction in long conversations: up to `99%`
-- Prompt size reduction: about `50%`
-
-### Additional results
-

+
+## Run metadata
+
+- Date: 2026-05-06
+- Context Compiler: 0.6.15
+- Command: `uv run python -m demos.run_demo all`
+
+Provider/model selection is done via environment variables:
+
+- `PROVIDER` (`openai`, `ollama`, `openai_compatible`)
+- `MODEL`
+- `OPENAI_API_KEY` / `OPENAI_BASE_URL` as required by provider mode
+
+Scoring behavior uses post-audit oracle/checker logic in demos and shared helpers:
+
+- `demos/01_llm_contradiction_clarify.py`
+- `demos/02_llm_constraint_guardrail.py`
+- `demos/03_llm_premise_guardrail.py`
+- `demos/04_llm_tool_denylist_guardrail.py`
+- `demos/05_llm_prompt_drift_vs_state.py`
+- `demos/07_llm_prompt_vs_state.py`
+- shared parsing/helpers in `demos/common.py`
+
+## Interpretation
+
+- Live demo runs are **evidence/smoke tests** across real model/provider behavior.
+- Deterministic test suites (unit/property tests) are the **regression authority** for oracle and engine contracts.
