Workshop Assemble

When exiting the workshop

Workshop exit returns to the Decision gate in estimate-assemble.md § “Post-Estimate: Decision Gate” — never directly to Generate. The user chooses A (done for now) or C (generate) there; the active scenario carries into either choice.

1. Set preferences.workshop.active to false (keep active_scenario_id).

2. Ensure scenarios/index.json exists (baseline-only is enough if user entered then exited without Apply).

3. Update .phase-status.json (read-merge-write):

   • phases.workshop → "completed" (sidebar resolved — participated)
   • current_phase stays "estimate" (the Decision gate sets the next state based on the user’s choice)
   • Do not touch run_mode here — the gate is the only writer.
   • last_updated → now

4. Emit:

   Copy

   HANDOFF_OK | phase=workshop | artifacts=scenarios/index.json | return_to=decision_gate

5. Output: “Workshop done. Active scenario: {id}.” Then re-present the Decision gate from estimate-assemble.md (options A and C — the workshop was just explored, so omit B), with the gate’s verdict/cost lines refreshed from the active scenario’s estimation-infra.json.

When declining at Estimate offer (no entry)

Handled in estimate-assemble.md / SKILL.md — set phases.workshop to "completed" without requiring scenarios/. Participation signal = presence of scenarios/index.json.

Soft postcondition

If the user exits without any scenario directory (edge case), emit _warn_and_skip for the scenarios postcondition and still mark workshop "completed" — then return to the Decision gate per above (never advance to Generate directly, even on this soft path).
