* feat: add confirmed Take down stack action with optional volume removal
Expose Take down in the stack header and sidebar with a confirmation dialog
that runs compose down while keeping the stack definition on disk. Optional
volume removal is gated by node capability and stack:deploy permission, with
remote gateway preflight before proxying removeVolumes requests.
Closes#1582
* fix: reset take-down volume checkbox when dialog closes
* test: align getStackMenuVisibility assertions with showTakeDown key
getStackMenuVisibility now returns a fifth lifecycle flag, showTakeDown,
but three exhaustive toEqual assertions still listed only the prior four
keys and failed. Add the expected showTakeDown value to each: true for
the partial and exited running-stack cases, false for the self stack.
* test: cover Take down visibility for running non-self stacks
The getStackMenuVisibility assertions exercised the partial and exited
branches and the self-stack guard, but not the raw === 'running' literal
that drives showTakeDown for a normal running stack. Add a case so a
regression dropping 'running' from that check is caught.
* fix: drop Take down from header overflow and wire activity shortcut
Remove duplicate Take down from More actions.
Keep inline button when running, sidebar menu, and Cmd+ArrowDown.
Record stack_taken_down in activity on successful POST /down.
POST /api/stacks/:name/{deploy,down,update} previously returned HTTP 500
with body {"error":"spawn docker ENOENT"} when invoked against a stack
whose compose directory was missing. The status code was wrong (the
named resource did not exist, so 404 is the right answer) and the
message misled operators into thinking the docker CLI was unavailable.
Add a small requireStackExists(nodeId, stackName, res) helper in
routes/stacks.ts that validates the stack name and confirms a compose
file is present via FileSystemService.hasComposeFile before any of the
three handlers spawn docker compose. The helper is called immediately
after requirePermission and before runPolicyGate so unauthorized
callers still get 403 first and the policy gate never runs against a
phantom stack.
In ComposeService.execute(), narrow the child.on('error') handler so
the genuine docker-binary-missing case (ENOENT on the spawn itself)
rejects with "Docker CLI unavailable on this node" instead of the raw
"spawn docker ENOENT". This is defense in depth for the rare case the
pre-check cannot cover, and it fixes the misleading-message half of
the bug as well.
Cover the new contract with stack-actions-missing-stack.test.ts (four
cases: deploy/down/update return 404, invalid name returns 400). Mock
ComposeService as a tripwire so a future code path that bypasses the
guard would fail loudly. Fix stacks-failure-notifications.test.ts by
adding hasComposeFile to its FileSystemService partial mock so the
existing happy-path-error-handling cases continue to flow into
ComposeService.
