* Rewrite DSH gateway for browser sessions, HTTP and WebSocket - Replace the Flask proxy with a Starlette ASGI app (uvicorn factory), keeping the control plane (claims, wake/suspend, idle sweeper). - Add HttpOnly gateway sessions and a server-side DSH launch-token handshake: read the token from pod logs, exchange it for a dsh-auth cookie, cache per (user, pod UID, Host), refresh once on 401. - Proxy HTTP/SSE and WebSocket (/api/remote.mux) under /u/<user>/, with header stripping/injection, Location rewriting and wake-on-connect. - Add a landing/signup/login page, health endpoint, pinned dependencies, a read-only-rootfs gateway image, 87 cluster-free tests and docs. * Fix DSH probe crash-loop and harden gateway manifests - Probe /favicon.svg instead of /: DSH gates / behind its launch-token cookie and returns 401, which made warm-pool pods crash-loop. - Pass DSH_TRUSTED_HOSTS through the entrypoint as --trusted-host args for public/ingress hosts; keep localhost trusted. - Deploy the published :gateway image, add pods/pods-log RBAC, /healthz probes, read-only rootfs with a /tmp emptyDir and non-root security. - Add optional Traefik Ingress and document the prerequisites. * Update CI, smoke tests, build tooling and docs - Run gateway pytest/ruff and build/smoke-test the image in CI. - Parameterize the DSH build version and pnpm version inputs. - Exercise cookie signup, HTML proxy, WebSocket auth, suspend/wake and delete in run-test-kind.sh. - Add Makefile/build.sh targets and document the architecture, handshake, probes, trusted hosts, troubleshooting and limitations. --------- Co-authored-by: SREDevOpsAgents <agents@sredevops.org>
