Run Parallel-Safety Evaluation. Produce one plan doc per plan from D-phase. </purpose>

<inputs>
  Session state from code-structure:
  - bundle_dir, ticket_path, ticket_alias, ticket_slug, primary_tag
  - design_path (locked), structure_path (locked)
  - plan_count, slices
</inputs>

<outputs>
  Per plan: plan-YYYY-MM-DD-{ticket_slug}.md OR
  plan-YYYY-MM-DD-{ticket_slug}-plan-{n}.md for multi-plan.

  Each plan doc contains:
    - Per-slice tactical steps (test → impl → green → verify → commit)
    - Dependency ordering between slices
    - Verification commands per slice
    - Commit message convention
    - Parallel-Safety section (in plan-1.md only if multi-plan)
</outputs>

<discipline>
  TDD vertical-slice MANDATE per Lock 8: one test → one impl →
  repeat. NEVER horizontal (all tests then all impl). Horizontal
  slicing produces crap tests that test shape instead of behavior.

  No open questions in the final plan. Spot-check user review only
  (alignment already done in D/S).
