The local Comfy agent runs every comfy-cli invocation inside a kill-on-close Job Object. Children spawned with DETACHED_PROCESS | CREATE_NEW_PROCESS_GROUP remain members of that job, so `comfy model download --background` workers, the `comfy run` watcher and the templates cache refresher were killed as soon as the command returned (a background download stuck at "starting"). Add comfy_cli.detach.popen_detached, which on Windows also passes CREATE_BREAKAWAY_FROM_JOB and, if the enclosing job forbids breakaway (ERROR_ACCESS_DENIED), retries once with the previous flags. POSIX keeps start_new_session=True. Use it at all three detach sites. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…t a ComfyUI repo `comfy --skip-prompt install --nvidia` into a pre-existing, non-git workspace directory printed "'<path>' exists but is not a valid git repository." and installed nothing, but emitted no JSON envelope (and older releases exited 0), so an agent could not tell it failed. Route the refusal through renderer.error with two new registered codes, install_target_not_git_repo and install_target_not_comfyui (details.path, details.remotes), a hint to choose another --workspace or remove/rename the folder, and exit 1. A versioned install (--version X) now also rejects a pre-existing non-git folder up front instead of attempting a checkout in it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

remotes to strip URL userinfo credentials before values enter remote_urls, so
both message and details.remotes receive only redacted URLs. Update the
associated regression test to assert the redacted remote value and ensure
credentials never appear in repeated output.
- Around line 267-269: Update the install-target validation around
check_comfy_repo and _is_git_repo so a non-Git directory is accepted only when
resolved_path identifies repo_dir itself; if validation resolves to a parent
ComfyUI root, call _reject_invalid_install_target(repo_dir). Preserve parent
discovery for workspace detection while keeping the root check rooted to the
requested install directory.

… may exist'
`comfy deploy run` from the local Comfy agent failed with
deploy_job_submit_unknown ("the job may exist ... do not resubmit") because the
agent's egress proxy refused the deployment host: the CONNECT tunnel was
refused before a byte of the request was sent. A refused connection, a DNS
failure or a refused proxy tunnel now raise deploy_endpoint_unreachable naming
the host (no job exists; fix the path and submit again). Timeouts and anything
after the request was sent stay deploy_job_submit_unknown.

…the install dir - Strip URL userinfo from git remotes before they reach the install_target_not_comfyui message and details.remotes (https://user:tok@host/x -> https://***@host/x; scp-style git@host:x is left as is). - check_comfy_repo walks up to a parent checkout, so a non-git <ComfyUI>/leftover passed install.execute's target check. Accept a target only when the resolved ComfyUI root is repo_dir itself; workspace detection keeps parent discovery. - Test mocks of check_comfy_repo now return the real (True, repo_dir) shape instead of (True, None).

Summary
Two fixes found while running the local Comfy agent end to end on a Windows 11 box (RTX 5090), where the agent drives comfy-cli for installs, model downloads, runs and builds.
1. Detached workers now break out of the parent Job Object (Windows). The local agent runs every comfy-cli invocation inside a kill-on-close Job Object.
comfy model download --background, thecomfy runwatcher and the templates cache refresher detach withDETACHED_PROCESS | CREATE_NEW_PROCESS_GROUP, but the child stays a member of the parent's job. It was killed as soon as the command returned, so a background download stayedstartingforever. The newcomfy_cli/detach.py:popen_detachedaddsCREATE_BREAKAWAY_FROM_JOB. If the enclosing job forbids breakaway (ERROR_ACCESS_DENIED), it retries once without the flag, which is the old behaviour. POSIX is unchanged. The agent side (JOB_OBJECT_LIMIT_BREAKAWAY_OKon its job) is in Comfy-Org/cloud#9503.2.
comfy installinto an existing non-git folder now reports an error envelope. It already exited 1, but in--jsonmode it printed no envelope. It now emitsinstall_target_not_git_repo(orinstall_target_not_comfyuifor a git repo with a foreign remote), withdetails.pathand a hint to pick another--workspaceor move the folder. Both codes are registered inerror_codes.py.3. A deploy submit that never reached the endpoint is no longer "the job may exist". When the local agent's egress proxy refused the deployment host (
<dep-id>.stg.run.comfy.app),comfy deploy runreporteddeploy_job_submit_unknownand told the caller not to resubmit, though the CONNECT tunnel had been refused before any byte of the request was sent. A refused connection, a DNS failure, or a refused proxy tunnel now raisesdeploy_endpoint_unreachable, withdetails.hostnaming the endpoint: no job exists, so fix the path and submit again. Timeouts, and any failure after the request was sent, staydeploy_job_submit_unknown. The code is registered, and the comfy-deploy-failures skill table is updated.Testing
