• Acceptance umbrella / blockers: GitHub Ship a public-source tour and repeatable screenshots #15; blocked by U01, U13, U22, U24, U25, and U27.
• Outcome: A small attractive invented-data multi-page Bundle and deterministic seed/publish/tour demonstrate Invitation, Shelf, private Site, republish/rollback, offline keeping/update, feedback, receipts, revocation, and deletion without real/private/proprietary data or anonymous hosting.
• Failure/recovery: Non-deterministic clock/data, stale state, external/private assets, license ambiguity, anonymous exposure, and failed reset make the tour fail explicitly.
• Evidence: Example validation/license scan, deterministic seed and full real-browser tour, repeatable cleanup, local docs usability, and privacy/license review.
• Central surfaces / impact: Example source/fixtures, tour harness, deterministic data/clock. Screenshot capture is U34.
• Safe split: Example Bundle and scripted tour may checkpoint separately, but the example is not accepted until the real app completes every named state.

Every integration records a factory candidate with evidence or No reusable harvest.
