"""Tests for the 2026-07-02 directive scavenge lift.

The scavenge pass lifted 15 new directives from previously-unscanned markdown
(MMA_Support, nagent_review, intent_dsl_survey, docs/handoffs). These tests
encode the structural contract for those new directives:

  - 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 from 66 to 81

These tests are additive to tests/test_aggregate_directives.py (the existing
contract tests for the aggregator script). The new tests here pin the
scavenge-pass output so a future agent can verify the lift was complete.
