+### Watch the flywheel turn — one command
+
+For a public-facing reproduction of the core thesis, in **four
+falsifiable scenes**:
+
+```bash
+core demo flywheel
+```
+
+This runs end-to-end on the canonical pack:
+
+1. **Ratify** — `apply_composition_claim()` writes a reviewed JSONL
+   artifact; RAT-1's `compile_pack` regenerates the runtime
+   `compositions.jsonl` + updates the manifest checksum.
+2. **Load** — `composition_registry` reads the new entry on the next
+   runtime turn.
+3. **Solve** — a real problem (`"Lilibeth fills 6 baskets where each
+   basket holds 50 strawberries. How many strawberries does Lilibeth
+   have?"`) admits via the matcher → injector → admission chain and
+   produces `answer=300`.
+4. **Hazard** — case 0050 (the `wrong=0` canary) remains refused —
+   no SAFE composition category can convert it from refused to
+   wrong.
+
+Every scene is byte-deterministic; the canonical pack is read-only
+throughout; the demo mutates only a synthetic test pack in a
+tempdir. See [`evals/flywheel_demo/run_tour.py`](evals/flywheel_demo/run_tour.py).

+core teaching coverage --use-reader        # per-shape histogram + hazard pin status

+"""Public-proof demo — one command that shows the math composition
+flywheel turn one revolution end-to-end on a clean pack.
+
+The thesis of the position paper is *decoding, not generating* — that
+cognition is the deterministic decoding of structure that already
+exists, and that the load-bearing invariant is `wrong == 0`.
+
+This demo executes a four-scene reproduction that any visitor can run
+after `git clone && uv pip install -e .`:
+
+    Scene 1.  BEFORE.   On a clean pack with no composition ratification,
+              "Maria bought 3 books at $5 each. How much did she pay?"
+              REFUSES. The recognizer matches; the injector returns ();
+              the candidate-graph refuses with a named reason.
+
+    Scene 2.  RATIFY.   Operator submits one ratification:
+                  apply_composition_claim(
+                      claim=<MathReaderRefusalEvidence>,
+                      composition_category="multiplicative_composition",
+                      polarity="affirms",
+                      surface_pattern="bound(count) × bound(unit_cost)",
+                      reviewer="public_demo",
+                  )
+              Followed by:
+                  core teaching seed-recognizer \\
+                      --shape-category rate_with_currency \\
+                      --anchor-kind currency_per_unit_composition \\
+                      --observed-currency-symbols '$' \\
+                      --observed-per-units each apiece
+
+    Scene 3.  AFTER.    Same prompt now ADMITS with answer=15.
+              Every transition between Scene 1 and Scene 3 is one of:
+                - a reviewed JSONL append to compositions/{category}.jsonl
+                - a reviewed proposal log append
+                - the deterministic compile_pack step (RAT-1)
+              No training, no gradient, no sampling.
+
+    Scene 4.  HAZARD.   case 0050 ("Mark does a gig every other day for
+              2 weeks") REMAINS REFUSED after ratification. The hazard
+              pin (gsm8k-train-sample-v1-0050, the wrong=0 canary) is
+              load-bearing.  Architecturally, no composition admission
+              under SAFE_COMPOSITION_CATEGORIES can convert this case
+              from refused → wrong.  Verified live.
+
+All four scenes are byte-deterministic. Re-running the demo on the
+same git revision produces the same outputs. The state mutation
+(scene 2) is contained to a synthetic test pack in a temporary
+directory; the canonical pack is read-only throughout.
