fix(cli): name the gateway that owns an unseen sandbox#10747Dongni-Yang wants to merge 3 commits into
Conversation
On a multi-gateway host, a sandbox owned by another gateway reported only "Sandbox 'X' does not exist" alongside the selected gateway's sandboxes. The reader could not tell which gateway to restore or select, and the message denied a sandbox NemoClaw had recorded. Registry reads are pinned to the selected gateway's state root, so the row is structurally invisible. Registry recovery cannot rescue it either: its live probe is deliberately gateway-scoped, because an unscoped list once bound a sibling gateway's sandboxes to the selected gateway (#7105). `findForeignGatewaySandbox` consults the existing host-wide reader and reports the owning gateway, its port, its registry file, and a rerun command scoped with NEMOCLAW_GATEWAY_PORT. It only reports: no row is adopted, so the #7105 scoping stays intact. The lookup returns null when any host registry is unreadable. That reader fails closed for its allocating callers, which is right for them and wrong here — the sole caller is a diagnostic on an already-failing command that must still exit 1 cleanly rather than throw a stack trace over the real error. This follows the read-only carve-out `safeListRegistryEntries` established. The unknown-sandbox message is unchanged whenever no other gateway claims the name, which is every single-gateway host.

- Around line 290-293: Update findForeignGatewaySandbox and its caller to detect
all hostEntries matching sandboxName with a gatewayPort different from
selectedGatewayPort, rather than using find to select one. Represent the
ambiguous case with all matching gateway ports and ensure the diagnostic does
not emit a single rerun command for an ambiguous sandbox name.

Nothing enforces host-wide sandbox-name uniqueness, so two gateway roots can each register the same name. Selecting one claimant meant the printed rerun command named whichever gateway sorted first by port, which could send status or recover to the wrong gateway while looking authoritative. The lookup now returns every claimant and the diagnostic lists each gateway with its own rerun command, so an ambiguous name is reported as ambiguous instead of resolved arbitrarily. Single-owner output is unchanged. From CodeRabbit review. Signed-off-by: Dongni Yang <dongniy@nvidia.com>

Accepted and fixed in Duplicate names are reachable. Nothing enforces host-wide sandbox-name uniqueness. I built a temporary No throw — the port-mismatch guard only rejects a row whose Fix. I took the "return an ambiguity result" option rather than enforcing host-wide uniqueness. Uniqueness is a product decision with migration consequences for hosts that already have colliding names, and it does not belong in a diagnostic fix. Reporting the ambiguity is strictly honest: the command names every candidate and lets the reader choose, instead of resolving arbitrarily while looking authoritative. Single-owner output is byte-identical to before. Tests. Two added, both verified red against the previous single-owner behaviour by narrowing the lookup to its first match:

Outcome
On a multi-gateway host,
nemoclaw <name> statusandnemoclaw <name> recovernow name the gateway that owns a sandbox the selected gateway cannot see, instead of reporting that the sandbox does not exist.Before:
After:
Reason
Registry reads are pinned to the selected gateway's state root —
REGISTRY_FILEresolves throughnemoclawStateRoot(HOME, GATEWAY_PORT)— so a row written under another gateway is structurally invisible, andrecoverRequestedSandboxIfNeededfalls through to the unknown-sandbox message.Registry recovery cannot rescue it, and must not be changed to. Its live probe is deliberately
-g-scoped, because an unscopedsandbox listreturns every sandbox on the host and once caused recovery to bind a sibling gateway's sandboxes to the selected gateway (#7105). That scoping is pinned by an existing test asserting the probe never issues a baresandbox list.So the answer is not to widen recovery, but to report the owner. The host-wide reader already exists —
listHostGatewayRegistryEntries— and was simply never consulted on this path.Related issues
Closes #10656
Changes
src/lib/state/gateway-registry.ts—findForeignGatewaySandbox(name, selectedGatewayPort, home)returns every other gateway root claiming the name — name, port and registry file each — ornull. Nothing enforces host-wide sandbox-name uniqueness, so naming a single claimant would point the rerun command at whichever gateway sorted first by port. It only reports; no row is adopted, so the [DGX Station][Sandbox] nemohermes queries the wrong sandbox after the active OpenShell gateway changes #7105 scoping is untouched. Both new imports are added toimportstatements that already exist, so the module graph gains no new edge.src/lib/cli/public-dispatch.ts— consults it after recovery has failed and prints the owning-gateway diagnostic. The existing unknown-sandbox block is byte-identical and still runs whenever the lookup returnsnull, which is every single-gateway host.test/support/public-dispatch-test-harness.ts— stubs the lookup for everywithDirectPublicDispatchcase. Without this the real function would read the developer's own$HOMEduring unrelated tests; nothing in the existing isolation helper redirects it.A deliberate asymmetry, and the main thing to review.
listHostGatewayRegistryEntriesfails closed — it throws on malformed JSON, a bad row, a symlinked root, or a gateway-port mismatch. That is correct for its existing callers, which allocate a dashboard port and decide a router teardown. It is wrong here: the sole caller is a diagnostic on an already-failing command, so a corrupt registry belonging to an unrelated gateway would replace a cleanexit 1with a stack trace over the real error.findForeignGatewaySandboxtherefore catches and degrades to "no owner", matching the read-only carve-outsafeListRegistryEntriesestablished. This does not weaken #8443: a corrupt selected registry still throws, earlier, fromregistry().getSandbox().NEMOCLAW_GATEWAY_PORT=<port> <command>is the documented mechanism for selecting a gateway (docs/reference/troubleshooting.mdx), and is already printed to users byrun-plan.tsandreadiness/gateway-production.ts, so this reuses the established remedy rather than inventing one.Verification
Five tests, all red before the source change and green after:
names the owning gateway instead of denying the sandbox for status/... for recover— the reported repro at the dispatch boundary. Asserts every new line, and asserts the output does not containdoes not existorRegistered sandboxes:, since the issue requires the message stop implying the sandbox is unknown.names the gateway that owns a sandbox the selected root cannot see— the real lookup against a two-gateway temporaryHOME, no mocks.reports no owner for a sandbox the selected gateway already holds.degrades to no owner when a sibling registry is unreadable— assertslistHostGatewayRegistryEntriesthrows on that same fixture and that the lookup still returnsnull, pinning the asymmetry above.Two more cover the ambiguous case, both red against a single-owner lookup:
reports every gateway that claims the same sandbox name— the real lookup over a three-root fixture.names every gateway when more than one claims the sandbox— the dispatch boundary, asserting both rerun commands.One guard passes in both states, so it pins preserved behaviour rather than restating the fix:
keeps the unknown-sandbox message when no other gateway owns the name.Commands:

statusandrecoverboth reach this path — confirmed against the builtsandboxActionTokensForDispatch(), which matches the issue's log block showing the identical message twice.The diagnostic needs no running daemon:
listGatewayStateRootsis a pure directory enumeration anchored on the default gateway port, so stopping the owning gateway — which is the reported scenario — does not affect it.PR #10335 also edits
recoverRequestedSandboxIfNeeded's neighbourhood in this file, for the unrelated bare-sandbox-action grammar. The two branches are semantically disjoint; whichever lands second takes a small textual conflict.Signed-off-by: Dongni Yang dongniy@nvidia.com
