fix(platform): take the Docker socket when both engines answer#10387Dongni-Yang wants to merge 4 commits into
Conversation
When the host's default Docker authority is proven dead and both a Docker-identified and a Podman-identified socket answer, detection returned null and set nothing. The CLI then kept the authority the probe had just observed to be dead, so preflight reported Docker unreachable on a host with a live, reachable Docker daemon — and nothing named the ambiguity, because no readiness message exists for it. Select the Docker socket instead: Docker is the engine NemoClaw targets, and the choice is no longer a guess between two unranked answers. Declining to choose is not neutral once the default is known dead; it leaves the host with nothing. This reverses the mixed-identity bail added for #8816 in #8823 and kept in #10253, whose security review recorded "two conflicting identified engines still fail closed" as a pass criterion. The bail fails closed on a host that has a working Docker daemon, which is the outcome #8816 itself asked to prevent: "NemoClaw must not replace that working authority with an automatically discovered Podman socket." An explicit DOCKER_HOST still wins over all detection, and a Podman-only host still selects Podman. Refs #10367 Signed-off-by: Dongni Yang <dongniy@nvidia.com>

Recording the argument against this PR, so the decision does not rest only on the case for it. An independent review of the same code recommended keeping the guard verbatim and answering CodeRabbit in the thread instead:
So the question is whether to change a security-reviewed guard for a host state nobody has reported yet. My case for changing it stands on the failure being silent and unrecoverable when it does fire, and on #8816's own wording. Either ruling is fine by me — if you keep the guard, I will close this and add the actionable readiness message #8816 asked for and never got, which fixes the silence without touching the guard. |
The selection loop probed every remaining candidate after it had already settled on a Docker socket. Nothing later can beat Docker, and each extra probe is another synchronous Docker CLI run that a stale socket holds for the full three-second timeout — paid at CLI startup, because the runner detects at module import, and reported to the operator as a stalled command rather than as socket selection. Break on the Docker answer. A Podman answer still keeps scanning, because a later Docker candidate must replace it. The Linux coexistence test now records probe calls and proves the scan stops, which is the behaviour candidate order does not already give it. The macOS test remains the proof of the identity upgrade itself, where the Podman machine socket is probed before Docker Desktop. Refs #10367 Signed-off-by: Dongni Yang <dongniy@nvidia.com>

Addressed the advisory on Operations and Design/Architecture, both blockers — same defect. The loop kept probing after it had already settled on a Docker socket, and each extra probe is a synchronous Docker CLI run that a stale socket holds for the full three-second timeout, paid at CLI startup because the runner detects at import. It now breaks on the Docker answer. A Podman answer still keeps scanning, because a later Docker candidate has to replace it. Test design, blocker — keep the Linux test, with a different job. The finding is right that the Linux fixture did not exercise the upgrade: Instead it now records probe calls and asserts The two tests no longer overlap: one owns "Docker wins and the scan ends", the other owns "a later Docker answer replaces an earlier Podman one". |

The separate early-exit test carried a Podman candidate that answered reachable, which the scan can never observe once a Docker answer ends it. That dead setup reads as proof that Docker wins a race the test never runs. The existing Docker-fallback case already builds the same Linux fixture, so it takes the probe-sequence assertion instead, and its title now states what it proves: the scan ends at the Docker answer, whatever the later Podman candidate would have said. The macOS case remains the only owner of the identity upgrade, where a reachable Podman socket really is probed first and then replaced. Refs #10367 Signed-off-by: Dongni Yang <dongniy@nvidia.com>

Addressed the advisory on Code reduction. Taken. The separate early-exit test set the Podman candidate to This crossed the test-design specialist, which read the split as isolating distinct behavior. The reduction argument wins on a fact test design did not weigh: with the scan ending at Docker, the Podman result in that fixture is unobservable, so the two tests could not have been proving different things. The macOS case is now the sole owner of the identity upgrade, and it is the only fixture where a reachable Podman socket really is probed first and then replaced.

This cannot be approved without an accepted maintainer design decision that explicitly supersedes the existing mixed-engine fail-closed contract.
Cross-issue result: CONTRADICTING, high confidence. src/lib/platform.ts replaces the conflicting identified-engine return-null guard with Docker preference. Issue #8816 requires stale, unreachable, or ambiguous socket candidates to fail closed with an actionable result, and the security approval that merged #10253 explicitly treated preservation of the conflicting-engine guard as a pass criterion. This PR directly reverses both records.
The reversal is also not required to fix #10367: that report says the Podman socket is not serving, so the mixed-reachable-engine branch cannot fire. The stacked base #10379 addresses the observed default-probe and fallback path and is itself still REVIEW_REQUIRED.
Please do one of the following before rereview:
- Keep the guard and close this stacked reversal; address the silent conflict through a separately accepted issue for an actionable readiness diagnostic, as proposed in the PR discussion.
- Link an accepted maintainer design decision that deliberately changes the authority policy, defines the Docker-over-Podman security rationale and operator behavior, and supersedes #8816/#10253. The base PR must also be approved first.
Security review: categories 1-8 pass for this narrow diff; category 9 is WARNING because it weakens a recorded fail-closed boundary without accepted scope. All four commits are GitHub Verified and CI is green, but those gates do not establish product approval.

Taking option 1. Closing this reversal and keeping the mixed-engine fail-closed guard. Your reading matches what I put in the PR body and the follow-up comment: the reversal is not needed for #10367, because the reporter's Podman socket is not serving and the mixed-reachable-engine branch cannot fire on that host. I opened this stacked PR precisely so the guard change could be ruled on separately from the fix, and the ruling is clear. For the record of what remains: the silent half stands. When the guard does fire, nothing names the conflict — there is no readiness message for it anywhere in I will file that as its own issue for triage rather than carry it here, and I will not implement it before it is accepted. The base PR #10379 is unaffected and still carries the #10367 fix on its own. |

Filed as #10622 for triage, scoped to the diagnostic only, with the selection policy left exactly as it is. I am not implementing it before it is accepted. |
…10379) ## Summary NemoClaw probes Docker reachability by running `docker version` in a four-name environment (`HOME`, `USER`, `LOGNAME`, `PATH`), but every Docker command it runs afterwards gets the full subprocess allowlist. On a host whose daemon answers only through one of the dropped names, the probe reports the host's own default authority unreachable, detection falls through to the socket candidates, and the CLI pins `DOCKER_HOST` to Podman's rootless socket. Preflight then reports `Docker is not reachable` and points at the docker group, so onboarding stops at its first step on a host whose Docker is healthy. After this change the probe asks the same question the later commands answer, and detection never redirects the CLI on no evidence. ## Related Issue Closes #10367 This removes the mechanisms that produce the reported outcome: a probe environment narrower than the one the predicted commands run in, and a probe that reaches no verdict counting as a refusal. Either can send `DOCKER_HOST` to Podman's socket on a host whose Docker daemon is live. One honest caveat for whoever merges this. The reporter runs a DGX Spark with Docker and Podman installed; I have no such host and they have not yet answered the two diagnostic commands I asked for on the issue, so the cure is reasoned from the code path, not observed on their machine. If their `docker version` under the old four-name environment turns out to exit `0` quickly, neither fix explains their failure and the issue should be reopened rather than left closed. Two details from the report stay out of scope either way: the docker-group remediation text that names the wrong cause, and the `docker info` versus `docker version` disagreement on an unhealthy daemon. ## Changes - `buildDockerProbeEnv` now selects names with `isSubprocessEnvNameAllowed`, the same allowlist `buildSubprocessEnv` gives real Docker commands, and drops an ambient `DOCKER_HOST` so the probe still pins the authority under test. The probe predicts whether those commands reach a daemon, so it must not ask under a narrower environment: `SSH_AUTH_SOCK` authenticates an `ssh://` Docker context and the proxy names decide how a `tcp://` one is routed. (An earlier revision of this description claimed `XDG_RUNTIME_DIR` selects a rootless daemon socket for the Docker CLI. I tested that and it is false — the CLI ignores a listening `docker.sock` in the runtime directory — so the justification is corrected here and in the code comment.) - `probeDockerHost` reports `inconclusive` when the Docker CLI cannot be spawned or the 3-second probe timeout kills it, and `detectDockerHost` holds the host default in that case. A probe that never answered is not an observed refusal, so it must not move the whole CLI to a fallback socket. - Linux socket candidates are now ordered `/run/docker.sock`, `/var/run/docker.sock`, `/run/user/<uid>/docker.sock`, then Podman's. Rootless Docker's socket sits beside Podman's in the same runtime directory and was never a candidate. - `buildDockerProbeEnv` also applies `withLocalNoProxy`, which `buildSubprocessEnv` gives every real Docker command. Without it, forwarding the proxy names could route a probe of a local `tcp://` authority through a host proxy that the real commands bypass — the same defect class, reintroduced by the fix. - `ci/source-architecture-budget.json`: reading the shared allowlist raises the recorded fan-in of `src/lib/subprocess-env.ts` from 24 to 25. - Onboarding now bounds the existing `docker info` and `docker version` preflight calls at 15 seconds, so preserving an inconclusive default authority cannot leave onboarding waiting without a limit. ## Risk family `src/lib/platform.ts` puts this PR in the tier-3 `platform-install` family, whose required job is `cloud-onboard`. That workflow has no `pull_request` trigger, so it selects on the post-merge push to `main` rather than here. Say the word if you want a `cloud-onboard` run before merge and I will arrange it. ## Not in this PR CodeRabbit's merge-risk note and the PR Review Advisor both point at the mixed-identity bail: when the default authority is dead and both a Docker socket and a Podman socket answer, `detectDockerHost` returns `null` and the CLI keeps its dead default. That path is pre-existing and unchanged here, and removing it reverses a decision recorded in #8823 and #10253, whose security review cited it as a pass criterion. It is a maintainer call, so it is a separate stacked PR — #10387 — with the reversal argued.

Summary
Stacked on #10379 — review that one first; this PR's diff is the last commit only.
When the host's default Docker authority is proven dead and both a Docker-identified and a Podman-identified socket answer,
detectDockerHostreturnsnulland sets nothing. The CLI then keeps the authority the probe just observed to be dead, so preflight reportsDocker is not reachableon a host with a live, reachable Docker daemon. Nothing names the ambiguity, because no readiness message exists for it. After this change detection selects the Docker socket.Related Issue

This reverses a recorded decision — please rule on it
The mixed-identity bail came from #8816 through #8823, and #10253 kept it. The #10253 security review recorded it as a pass criterion: "An unidentifiable reachable socket is skipped, while two conflicting identified engines still fail closed", and "does not weaken the conflicting-engine guard". This PR weakens exactly that guard, so it is a maintainer call, not a bug fix I can make unilaterally. My argument for it:
grepoversrc/lib/readiness,src/lib/onboard/preflight.ts, andsrc/lib/advisoriesfinds no message naming a socket conflict, so the operator sees only the [DGX Spark][Onboard] NemoClaw forces DOCKER_HOST to podman's rootless socket on hosts that have podman installed, so preflight reports Docker unreachable and onboarding cannot start #10367 symptom and the unrelated docker-group remediation. Docker readiness selects rootless Podman when Docker and Podman sockets coexist #8816's own criterion was to fail closed with an actionable result; that half was never built.DOCKER_HOSTstill short-circuits all detection (#8816regression test unchanged), a Podman-only host still selects Podman, and an unidentifiable socket is still skipped (detectDockerHost aborts on first ambiguous socket instead of trying remaining candidates #10248).If you would rather keep the guard, say so and I will close this PR and instead add the actionable readiness message #8816 asked for. CodeRabbit raised the same defect on #10379 as its merge risk, so one of the two paths should land.
