The suite covers the provisioned happy path and the dispatch-failure cleanup. Two guarded branches in
packages/cli/src/cli/commands/fleet.tsstill have no test:
provisioning_timeoutat Lines 237-253, which must delete the sandbox and throw a message that names the node and the waited duration.- The missing Relayfile mount at Lines 254-267, which must delete a
provisionedsandbox that reportsrelayfileMounted: falseand then throw.Both branches perform a delete and then fail the command, so a regression there silently leaks a Daytona node. Stub

Inline comments:
In `@CHANGELOG.md`:
- Line 12: Update the changelog entry for “agent-relay fleet spawn” so the
Relayfile workspace mount and starting in /workspace are described as the
default behavior, while explicitly noting that --no-sandbox-relayfile disables
this behavior and permits a bare sandbox.
In `@packages/cli/src/cli/commands/fleet.test.ts`:
- Around line 563-565: Move the RELAY_AGENT_TOKEN environment mutation in the
fleet spawn test inside its try/finally protection so any setup failure still
restores the original value. Update the test around the previousToken setup and
cleanup, preserving restoration for both successful and failed execution paths.
In `@packages/cli/src/cli/commands/fleet.ts`:
- Around line 228-253: The ensureCloudFleetSandbox failure path cannot clean up
when provisioning succeeded server-side but normalization or transport fails;
update the caller around ensureCloudFleetSandbox to extract and report the
sandbox identifier from the rejected error payload, instructing the user to
clean it up manually. Preserve existing cleanup for provisioning_timeout and
spawn failures, and coordinate the endpoint/error-payload contract with the
ensure implementation so the identifier is returned on these failures.
- Around line 283-297: Update the temporary launcher creation flow around
workspaceRelay.workspace.register so the resulting agentToken is restricted to
placement spawning only; since register does not support scopes, use an existing
capability mechanism before minting the token, or remove the implicit launcher
creation rather than issuing an unrestricted agent token.
In `@packages/cloud/src/fleet-sandbox.ts`:
- Around line 190-214: Bound both exported functions, ensureCloudFleetSandbox
and deleteCloudFleetSandbox, by adding a shared optional signal or timeoutMs
option with a default exceeding the CLI’s 90-second server wait, and forward it
in each authorizedApiFetch request init. Apply the ensure-request change at
packages/cloud/src/fleet-sandbox.ts lines 190-214 and the corresponding option
forwarding at lines 230-238.

- Around line 253-254: Use separate bounded signals in the provisioning flow:
pass a workspace-resolution signal to resolveCloudWorkspaceId, then create the
provisioning signal only after resolution completes and use it for the
provisioning POST. Add a regression test covering delayed workspace resolution
followed by a 90-second provisioning response, ensuring the request is not
aborted prematurely.
