+### PLT-003 - Align Platform Build Matrix With Phase 6 Targets
+
+Status: Done
+Score: +3 platform alignment and package parity
+Debt: `DEBT-0009`, `DEBT-0011`, `DEBT-0059`
+Scope: `scripts/automation/platform-build.ps1`, `scripts/automation/platform-build.sh`,
+`scripts/dev/check_platform_build_targets.py`, `scripts/dev/check_package_smoke_readiness.py`,
+`tests/CMakeLists.txt`, `docs/modernization/roadmap.md`
+
+Goal:
+
+Keep the phase-6 platform matrix explicit and self-checking by aligning the
+platform-build and package-smoke wrapper defaults, their self-tests, and the
+roadmap/debt notes with the current supported preset set. The wrappers should
+stay the source of truth for named validation commands.
+
+Done Checks:
+
+- `panopainter_platform_build_target_matrix_self_test` and
+  `panopainter_package_smoke_readiness_self_test` cover the current platform
+  preset/package matrix.
+- The roadmap and debt log mention the current platform-build/package-smoke
+  coverage and remaining platform shell gaps.
+- The wrapper defaults stay synchronized with the self-tests.
