go-on

Resume the work, whatever stopped it. Step 0 classifies the stoppage from recorded evidence and routes; Steps 0b–10 are the interrupted-review-workflow lane it routes to.

Portable helper resolution (workflow lane)

Resolve every lifecycle helper before entering Steps 0b–10, not before Step 0: classification needs only the stop-state helpers resolved in 0.2, and a resume that just routes to /pause-resume must not be blocked by a missing merge-gate helper it will never call. Inside the workflow lane a missing helper blocks rather than guessing which completed state is safe.

Walk through the full review lifecycle checklist in order. At each step, check if it's already been completed. Stop at the first incomplete step and execute it, then continue to the next step. Keep going until the workflow is complete or a blocking condition is hit.

Output a status line at each step so the user can follow along:

• [DONE] — step already completed, moving on
• [ACTION] — step incomplete, executing now
• [BLOCKED] — step cannot proceed, reporting why
• [SKIP] — step not applicable
