"""Tests for the 2026-07-03 scavenge sweep (batch 2/5: docs/superpowers/specs/).

Lifted 16 new directives from 22 design specs in docs/superpowers/specs/.
These tests pin the structural contract:

  - every new directive has both a v1.md and a meta.md file
  - every new directive's v1.md body starts with a '# ' imperative heading
  - every new directive's meta.md has the ## v1 section + Source/Lifted lines
  - every new directive is referenced in conductor/directives/presets/current_baseline.md
  - the total directive count grew by 16 from this batch

Additive to tests/test_scavenge_batch_1.py and tests/test_scavenge_directives_lift.py
(the prior scavenge-pass tests).
