PASTA Threat Model Dispatcher (Sequential)

Dispatch 7 PASTA stages in strict sequential order. Unlike all other framework dispatchers, PASTA runs each stage as a Task, waits for its output, and passes that output into the next stage's prompt. This is because PASTA is a risk-centric process where business objectives (Stage 1) constrain technical scope (Stage 2), which constrains decomposition (Stage 3), and so on through risk analysis (Stage 7).

Do NOT run stages in parallel. Do NOT skip stages. Do NOT reorder stages.

Stage Failure Handling

If a stage fails (returns empty output, errors, or times out):

1. Record the failure: stage number, error details, partial output if any.
2. Check if remaining stages can proceed:
   • Stages 1–3 are foundational. If any fails, STOP the pipeline and report partial results from completed stages.
   • Stages 4–7 can run with degraded input from prior stages. Note the gap explicitly in their output.
