Reimplements the same 4-user source-access matrix using Oracle AI
Database 26ai's Deep Data Security (DDS) — VPD's declarative SQL
successor. Coexists with the VPD demo (ddsuser_* / dds_* prefixes,
MAC intentionally not enabled on shared views).
- sql/adb/13_dds_variant.sql: CREATE END USER + CREATE DATA ROLE +
CREATE DATA GRANT for the same 4-user matrix; row-filter and
column-mask variants shown as commented examples.
- docs/05-dds-variant.md: prereqs (23.26.2+, COMPATIBLE>=20.0),
VPD <-> DDS 1:1 mapping table, run + teardown snippets.
- .env.example: DDSUSER_*_PASSWORD block (3b).
- README.md: tree + "더 깊이" link.
Not wired into run.sh — kept manual since DDS requires 26ai.
