New runbook

Editing needs a wider window. On a phone this page is read-only — the catalog and every record work at any size, and the reasoning is in the specification. A step list on a small screen would show a sequence while the document is a graph, and teach the shape wrong.

Add a step

A step is created with its kind. There is no placeholder: a node nobody has decided about ends up in a draft, then in an undo stack, then in a file.

Canvas

Editing the graph will not reformat this file or drop its comments.

Nothing yet. Begin with a check, not an action: a procedure that starts by changing something has already skipped the part where you find out whether it needed changing.

Inspector

Select a step to edit it. Marking one destructive or irreversible offers the pairing invariant 5 requires, in one action. Validation is the catalog's own linter — the same checks that decide whether a record publishes, running here rather than after you send it.

Checking…

Take it with you

No account and no email. Every file is built here, from the document above, and never sent anywhere.

Nothing to export yet — add a step above.

No draft in this browser.

Drafts stay in this browser. Nothing is sent anywhere until you publish, and publishing is a separate, explicit act — the editor is not a service.
