Archive — Pass 2 receipt walkthrough capture

Archive — not current documentation. Files in the last two groups describe the Seal family of research repositories or a past design state — they are kept for the record and are not claims about the Node CLI this repository ships.

Historical measurement, 18 September 2026.

This walkthrough was exercised on Linux with Seal v0.4.0 and the checker revision listed in sources. A freshly emitted demo receipt passed signature, argument/config commitment and local replay checks. Changing its argument produced a commitment refusal. This establishes the observed example’s compatibility, not every number or optional field allowed by the contract.

Source revisions and capture boundaries are recorded in Sources. This record describes the observed run, not a later release.
