From c8cbda985238411c127a3e32079c00fc9b7efe0a Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 28 Jun 2026 21:05:35 +0000 Subject: [PATCH 01/13] =?UTF-8?q?feat:=20complete=20alpha=20v1=20=E2=80=94?= =?UTF-8?q?=20e2e=20tests,=20federation,=20and=20Docker=20fixes?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add end-to-end integration tests for phases 0-3 (real Docker, live CoreDNS SOA query, step-ca ACME directory) and cross-world federation (PEERED mode DNS stub written to CoreDNS Corefile, NONE mode no-op). Fix two handler bugs uncovered during e2e work: - dns.py: CoreDNS started with network_mode=none then connected to 'core' network with static IP; volume mount changed ro→rw so GatewayPortalHandler can append stub zones at runtime - docker_handler.py: exec_command used demux=True but decoded .output as bytes; changed to demux=False for correct bytes output Add --run-e2e pytest flag, e2e marker, and CI e2e job (non-slow tests only, runs on ubuntu-latest with Docker pre-installed). Mark both roadmap items complete in README.

Add tests/fixtures/e2e-spec.yaml — identical to minimal.yaml except the core network uses 172.20.0.0/24 and all core-IP services use 172.20.0.x addresses. Both e2e test files now load this fixture instead of examples/minimal.yaml. The production example is unchanged.
