What

A new module reports how workshop artifacts progress from decisions through to a completed build.

Details
  • workshop_turn carries decisions_total, decisions_resolved and state; the slug and version are dropped as "nonconforming" unless they match strict regexes.
  • workshop_build_started fires once per slug when the state reaches "started".
  • workshop_build_completed fires once per slug with deliverables_n, deliverables_pr, deliverables_artifact and deliverables_other.
  • workshop_build_completed also carries a source of "structural" or "post_kickoff_republish", the latter after two republishes with no deliverables.
Evidence

workshop_build_completed

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
