Adds a Docker e2e test that exercises the user-visible stop-then-resume
flow: launch session, stop it via WS session.stop, launch a fresh
session on the same task, and assert the same task environment +
container ID are reused and the kandev feature branch is preserved.
Also nudge the executor popover padding: when the prepare-status
section is rendered above the Sprites/Docker info block, the cumulative
top+bottom paddings looked too generous around "Sprites sandbox" /
"Local Docker". Tighten both sections vertically without affecting the
horizontal rhythm or the bottom action row.
StopInstance was calling sprite.Destroy() unconditionally, so every
session stop tore down the cloud sandbox. Resume then always fell into
the missing-sandbox fallback, re-cloned the repo, re-ran the prepare
script, and lost the agent's working tree. That's a 30s+ round-trip
for what should be "stop the process, then re-attach later".
Limit Destroy to terminal lifecycle reasons (task/session
deleted/archived), the same set runTerminalCleanupScript already uses.
Plain stops just close the proxy and leave the sandbox alive.
Also update the existing Docker e2e regex: the feature-branch suffix is
now a deterministic 6-hex-char prefix of the task UUID rather than a
random 3-char tail, so resume on legacy env rows lands on the same
branch.
A new Playwright project — \`docker\` — runs container-bound E2E specs
against a backend with KANDEV_E2E_DOCKER=1. The fixture probes for a
Docker daemon and skips the worker entirely when none is reachable, so
contributors without Docker can still run the rest of the suite.
The fixture builds a tiny kandev-agent:e2e image once per machine
(node:22-slim + git/curl), pre-seeds a local_docker executor profile,
and seeds a local repo with a file:// origin so the executor's
clone-inside-container path resolves without network access. A small
WS-based session.launch helper is added to the api-client for tests
that need to launch additional sessions on an existing task.
First spec — docker-launch.spec.ts — covers the smoke path: a session
launches in a real container, the task environment records its
container_id, and \`docker inspect\` confirms the container exists.
Two follow-up specs (multi-session env reuse + recovery from external
container removal) are wired up but marked test.fixme with comments
pinpointing the backend gaps that block them: persistTaskEnvironment
isn't called for workflow-prepared sessions (so task_environment_id
stays empty on those rows), and DockerExecutor.reconnectToContainer
loses the agentctl handshake auth token across launches (so reconnect
401s and falls back to a fresh container every time).
Run locally with: \`pnpm --filter @kandev/web exec playwright test
--config e2e/playwright.config.ts --project=docker\`.
