Make the milestone 3 runtime story predictable instead of treating doctor, self-check, and startup failures as loosely related surfaces.
Split doctor and self-check into distinct read-only flows, add tri-state diagnostic status with stable IDs and next steps, and reuse that wording in CLI output, service logs, and tray-triggered diagnostics. Add non-mutating config/model probes, a make runtime-check gate, and public recovery/validation docs for the X11 GA roadmap.
Validation: make runtime-check; PYTHONPATH=src python3 -m unittest discover -s tests -p 'test_*.py'; python3 -m py_compile src/*.py tests/*.py; PYTHONPATH=src python3 -m aman doctor --help; PYTHONPATH=src python3 -m aman self-check --help. Leave milestone 3 open in the roadmap until the manual X11 validation rows are filled.
Capture the current GA gaps and define a portable X11 support contract so the release bar is explicit for mainstream distros.
Document five ordered milestones covering support policy, portable install/update/uninstall, runtime reliability and diagnostics, first-run UX/docs, and GA validation/release evidence.
Left generated artifacts (src/aman.egg-info) and prior readiness notes uncommitted.
