Rerunning a Spec #149

Parent

#139

What to build

Running a Spec again picks up where the last Spec run stopped.

• The Spec branch already exists, so the Spec run continues it (ADR 0002) rather than starting a numbered one, and reuses the draft Spec PR if there is one.
• Closed Tickets are done and not run again.
• A Ticket that failed before still has its Issue branch and draft PR, so its Run is a Continuation, targeting the Spec branch.
• Every Ticket closed, Spec branch exists: go straight to the Spec review and the Spec PR phase.
• Every Ticket closed, no Spec branch (the Spec was implemented some other way): stop with "every Ticket is closed and there is no Spec branch; nothing to do", exit 1, touching nothing, and without closing the Spec.

Acceptance criteria

• After a Failed spec run whose one Ticket failed, fixing the cause and rerunning continues the same Spec branch and the failed Ticket's Issue branch, and ends with a ready Spec PR
• The rerun does not start a Run for any Ticket closed in the first Spec run
• The rerun updates the existing draft Spec PR rather than opening a second
• With every Ticket closed and a Spec branch on origin, the rerun starts no Ticket Run and goes to the Spec review
• With every Ticket closed and no Spec branch, the Spec run prints the "nothing to do" message, exits 1, creates no branch or PR and leaves the Spec open
