The "they'd want to use it" first-run surface: a curated narrative that makes
the engine's discipline legible to a newcomer — bring a claim from any model and
watch it get decided, refused, or replayed. Proposer authority ignored.
Honest by construction (the risk with a narrative surface is theater):
- workbench/tour.py determinism_tour() is a curated ordered narrative BOUND to
the real demo registry. Intro (provider-agnostic thesis) → three demo steps
(deductive entailment decides only on engine+oracle agreement; epistemic
truth-state refuses a wrong proposer; proof-carrying promotion ignores
proposer authority) → payoff (replay-to-same-hash + the citable evidence
bundle).
- Each demo step's what_this_proves / what_this_does_not_prove cards and the
demo title are PULLED FROM THE REAL DEMO SPEC — never re-authored — so the
tour can never claim more than the demo it points at.
- A step referencing a missing demo FAILS CLOSED (KeyError), not a dead link.
Tests assert both (cards == spec; phantom demo raises).
Backend: schemas.py DeterminismTour/TourStep; GET /tour. schema-snapshot regen.
Frontend: /tour route registered in the registry (Determinism section, 14
routes; nav/palette/guide counts updated); TourRoute — thesis hero + ordered
step cards with the honesty cards + links to the real demos / replay.
Validation: 140 workbench Python tests incl. tour drift guards; 472/472 frontend
incl. routes/routeConformance/routes.docs (guide↔registry), Shell+palette counts
(14), schemaDrift, and the tour UI test; pnpm build clean; git diff --check
clean. No serving-path imports.
