+# Paragraph Flow
+
+Use this reference when the user asks whether a paragraph flows, makes sense, or
+is clear.
+
+## Core principle
+
+Flow is not decoration. A paragraph flows when an external reader can identify:
+
+- the paragraph's single message
+- how the first sentence announces that message
+- how each following sentence relates to the previous one
+- how the paragraph supports the section thesis
+
+## Reader test
+
+Read as a skeptical but fair external reader:
+
+1. Does the paragraph have one explicit message?
+2. Does the first sentence state what the paragraph is doing?
+3. Are all key nouns, terms and abbreviations readable without hidden context?
+4. Does each sentence connect by cause, contrast, consequence, refinement, or example?
+5. Is any sentence carrying material that belongs in another paragraph?
+
+## Reverse outlining
+
+For a section-level flow check:
+
+1. Write down the section thesis or main claim.
+2. Write down each paragraph's topic sentence.
+3. Write down the evidence or explanation under each paragraph.
+4. Check `topic sentence -> section thesis`.
+5. Check `evidence -> topic sentence`.
+6. Revise or remove any paragraph that cannot be mapped cleanly.
+
+If reverse outlining is hard, the section probably has a hidden structure problem.
+
+## Repair moves
+
+- Split paragraphs that contain two messages.
+- Move definitions before terms are reused.
+- Replace vague transitions with explicit relations such as `therefore`,
+  `however`, `by contrast`, `for example`, or `as a result`.
+- Add temporary subsection labels during revision, then remove labels that are
+  not needed in the final manuscript.
+- Keep paragraph openings claim-first unless the section needs a brief setup.
