Workshop

Execute ALL steps in order. Do not skip or deviate.

Prerequisites

1. $MIGRATION_DIR/.phase-status.json has phases.estimate == "completed".
2. Infra route artifacts exist: gcp-resource-inventory.json, preferences.json, aws-design.json, estimation-infra.json.
3. AI-only / billing-only NO-OP for this pilot: If gcp-resource-inventory.json is missing (AI-only or billing-only run), do not enter the infra workshop. Tell the user this pilot covers IaC infra repricing only; continue toward Generate / Feedback.

Entry

1. Do not re-run Discover / live CLI / Terraform parse.
2. If phases.generate is completed, require Estimate re-entry confirm and reset generate (and later) to pending before refreshing.
3. Set phases.workshop to "in_progress". Do not change current_phase (leave at "estimate" until exit/decline).

Loop

1. If scenarios/index.json missing → load workshop-refresh.md § Baseline capture.
2. Load workshop-sheet.md — present knobs + actions.
3. Branch:
   • Apply & reprice → workshop-refresh.md → workshop-compare.md
   • Compare scenarios → workshop-compare.md
   • Done / exit → workshop-assemble.md → returns to the Decision gate in estimate.md
   • Exit to full Clarify → danger; Clarify re-entry only on explicit confirm

Hard rules

These rules restate the canonical contract in references/vendored/workshop/workshop-invariants.md (vendored from skills/shared/workshop/workshop-invariants.md, kept byte-identical by shared:sync). When this table and that file disagree, the invariants file wins — fix this table.

Decline without entering

When the user chooses Decision-gate option A (done for now) or C (generate) without entering the workshop, mark phases.workshop "completed" (resolved/declined); the gate’s choice handling in estimate.md sets run_mode and current_phase.
