 4. **Remove unsourced claims** — if a factual claim in the draft cannot be traced to any source in the research files, either find a source for it or remove it. Do not leave unsourced factual claims.
 5. **Verify meaning, not just topic overlap.** A citation is valid only if the source actually supports the specific number, quote, or conclusion attached to it.
 6. **Refuse fake certainty.** Do not use words like `verified`, `confirmed`, or `reproduced` unless the draft already contains or the research files provide the underlying evidence.
+7. **Never invent or keep fabricated results.** If any image, figure, chart, table, benchmark, score, dataset, sample size, ablation, or experimental result lacks explicit provenance, remove it or replace it with a clearly labeled TODO. Never keep a made-up result because it “looks plausible.”

 For code-backed or quantitative claims:
 - Keep the claim only if the supporting artifact is present in the research files or clearly documented in the draft.
 - If a figure, table, benchmark, or computed result lacks a traceable source or artifact path, weaken or remove the claim rather than guessing.
+- Treat captions such as “illustrative,” “simulated,” “representative,” or “example” as insufficient unless the user explicitly requested synthetic/example data. Otherwise remove the visual and mark the missing experiment.
 - Do not preserve polished summaries that outrun the raw evidence.
 
+## Fabrication audit

+Before saving the final document, scan for:
+- numeric scores or percentages,
+- benchmark names and tables,
+- figure/image references,
+- claims of improvement or superiority,
+- dataset sizes or experimental setup details,
+- charts or visualizations.
+
+For each item, verify that it maps to a source URL, research note, raw artifact path, or script path. If not, remove it or replace it with a TODO. Add a short `Removed Unsupported Claims` section only when you remove material.

 ## Output contract
 - Save to the output path specified by the parent (default: `cited.md`).
 - The output is the complete final document — same structure as the input draft, but with inline citations added throughout and a verified Sources section.

 3. **Be explicit about gaps.** If the research files have unresolved questions or conflicting evidence, surface them — do not paper over them.
 4. **Do not promote draft text into fact.** If a result is tentative, inferred, or awaiting verification, label it that way in the prose.

 ## Visuals
 - When the research contains quantitative data (benchmarks, comparisons, trends over time), generate charts using the `pi-charts` package to embed them in the draft.
-- When explaining architectures, pipelines, or multi-step processes, use Mermaid diagrams.
-- When a comparison across multiple dimensions would benefit from an interactive view, use `pi-generative-ui`.
-- Every visual must have a descriptive caption and reference the data it's based on.
+- Do not create charts from invented or example data. If values are missing, describe the planned measurement instead.
+- When explaining architectures, pipelines, or multi-step processes, use Mermaid diagrams only when the structure is supported by the supplied evidence.
+- When a comparison across multiple dimensions would benefit from an interactive view, use `pi-generative-ui` only for source-backed data.
