fix(onboard): report an incompatible gateway database without an observed exit - #8992
Merged
Merged
Conversation
Installing a NemoClaw release that pins an older OpenShell leaves the gateway state database in place. The older gateway then refuses to open a database that the newer OpenShell wrote. It prints the raw sqlx text, which names no file and offers no remedy. The Troubleshooting block printed with it lists log and status commands that do not report the cause. classifyGatewayStartFailure now recognizes that failure. The Docker-driver start reporter prints the state database path and two recovery choices. The removal choice names the port-scoped state directory. Its parent also holds every other gateway port's state, so the message must not send the user there. OpenShell wraps the sqlx sentence across two lines, so the classifier matches the two halves separately. MigrateError::VersionMismatch shares the opening clause and reports a modified migration file, so the second half must match as well. The commands reference stated that uninstall removes ~/.local/state/nemoclaw unless the caller passes --keep-openshell or the gateway is externally supervised. It omitted the retained-sibling case. That case is the behavior that produced the original report. Signed-off-by: Hung Le <hple@nvidia.com>

…rved exit The incompatible-database diagnostic required `childExit.exited`. The start loop also reaches this reporter after its health poll budget expires, and after the child's liveness dropped before its exit event arrived. On the reported downgrade the gateway dies on this failure and the flag is false, so the diagnostic never printed and the user saw the raw sqlx text again. A DGX Spark reproduction confirmed this. The flag was false in every run: with the merged diagnostic the recovery block was absent, and the output matched the release that carries no diagnostic at all. The diagnosis now prints whenever the classifier matches. The state move keeps its safety instead of the whole block: when this process did not observe the exit, the diagnostic reports that fact and prints `pgrep -af openshell-gateway` as the precondition before the move. The commands reference stated that uninstall removes ~/.local/state/nemoclaw unless the caller passes --keep-openshell or the gateway is externally supervised. It omitted the retained-sibling case, where uninstall removes only the selected gateway port's subdirectory. Signed-off-by: Hung Le <hple@nvidia.com>

The previous revision printed the archive-and-move command after telling the user to run `pgrep` themselves. The managed gateway unit sets `Restart=on-failure`, so systemd can start a replacement between that check and the move, and the move then takes the state directory from a live gateway. PR review advisor finding PRA-1. The reporter now establishes the evidence itself. It accepts an `isGatewayProcessAlive` probe and offers the state move only when the child's exit event fired or the probe reported no live process. Otherwise it prints the stop command for the managed service and no move. Onboarding passes `isDockerDriverGatewayProcessAlive`, which reads the recorded pid and then confirms process identity. A bare `process.kill(pid, 0)` cannot serve here: the gateway is spawned detached and never reaped, so a crashed child stays a zombie and reports as alive, which would withhold the remedy on the exact path this PR exists to fix. The diagnosis and the database path still print in both cases, so the failure stays readable while the destructive step keeps its evidence requirement. Signed-off-by: Hung Le <hple@nvidia.com>
…tate move The liveness evidence arrived through a new `onboard.ts` argument, which grew the entrypoint by four lines and failed its growth guardrail. The evidence belongs in the focused module anyway: the reporter already resolves the state directory from the gateway log path, so it can read that directory's recorded process itself. `recordedGatewayProcessStopped` reads the recorded pid and then the process state. `process.kill(pid, 0)` cannot decide this, because the gateway is spawned detached and never reaped, so a crashed gateway stays a zombie and reports as alive. Reading the process state separates the two. An unreadable or absent record now returns false, so the reporter withholds the state move and prints the stop command instead. A missing record is not evidence that no gateway runs. `onboard.ts` returns to its state on main. Signed-off-by: Hung Le <hple@nvidia.com>

…able `recordedGatewayProcessStopped` returned true for every `/proc/<pid>/stat` read error. A permission error, or a host without procfs, does not establish that the recorded gateway process exited, yet that result released the printed command that moves the gateway state directory. Only a missing entry now reports the process as gone; every other error reports not stopped and keeps the stop-and-rerun guidance. Advisor finding PRA-1 and CodeRabbit both reported this. The pid record is now validated whole. `Number.parseInt` accepts a numeric prefix, so a record of "123invalid" passed as pid 123. The process state is read after the last parenthesis in the stat line. Field 2 is the executable name wrapped in parentheses and may contain spaces, so splitting the whole line returns the wrong field for such a name, and a recycled pid can carry one. Cover the function directly: a missing pid file, an unparsable record, a non-positive pid, a numeric prefix, a running process, an unreadable process state, and a pid no process can hold. The reporter tests reached only the missing-pid case through the default. The troubleshooting guide listed the archive path and the onboarding command as always printed, which contradicted the paragraph below it. Scope that sentence to the case where NemoClaw establishes that the gateway process stopped. Main removed a file under src/lib/onboard, so the source architecture budget measured 308 root files against a limit of 309 and asked for the lower value. This PR adds and deletes no file there.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Cover the zombie-process success path.
recordedGatewayProcessStopped returns true for either ENOENT or a parsed Z process state. This test covers only ENOENT. Add a mocked /proc/<pid>/stat record with a process name that contains spaces and state Z, then expect true. This tests the parser that can authorize the destructive state move.
As per path instructions, tests must provide behavioral confidence rather than implementation lock-in.

Reject PID values that cannot be represented exactly.
A digit-only PID can convert to Infinity or an unsafe integer. The /proc read then returns ENOENT, which reports the corrupted PID as stopped and can authorize the state move.
Reject non-safe integers before the /proc read. Add a regression test for a PID above Number.MAX_SAFE_INTEGER.

Two revisions tried to prove, before printing, that no gateway process held the state directory. Both were rejected. The managed unit sets `Restart=on-failure`, so a replacement can start between any check and the user's move, and a replacement started by the service manager does not write its pid where an earlier launch recorded one. No amount of reading closes that window. The recovery now runs the stop in the same command chain as the archive, the move, and the onboarding command, so no window exists. That removes the recorded process probe, its pid parsing, and the branch that withheld the move. `getOpenShellGatewayServiceStopCommand` resolves the owning service instead of deriving one from the platform. The resolver already picks between the upstream OpenShell package unit, the NemoClaw user service, and the Homebrew formula, and a platform guess would print `systemctl --user stop nemoclaw-openshell-gateway` on a host that runs the upstream unit. The stop would then fail and abort the chain before the archive and the move. When no service manager owns the gateway, the chain starts at the archive step. Cover the systemd chain, the Homebrew chain, and the standalone chain. The tests inject the resolver, so they no longer depend on the platform of the host that runs them. Advisor findings PRA-1 and PRA-2, and the CodeRabbit findings about pid parsing, all describe the probe this change deletes. Signed-off-by: Hung Le <hple@nvidia.com>

Handle service-resolution failure without aborting the failure reporter.
getOpenShellGatewayServiceStopCommand() can throw when the detected unit is untrusted or unsupported. Line 109 then aborts this reporter before it prints the recovery command, troubleshooting footer, or performs the configured process.exit(1).
Keep an untrusted stop command suppressed. Handle this result by printing a safe manual-stop instruction and do not print a destructive move command until service ownership is resolved. Add a regression test where resolveGatewayStopCommand throws.

<!-- markdownlint-disable MD041 --> ## Summary Portable onboarding resume now reconstructs its rootless Podman authority from a versioned checkpoint instead of inheriting process-local runtime selectors. Resume restores the recorded portable profile before admission, requalifies the canonical current-user socket and configuration under the onboarding lock, and fails closed on legacy, tampered, unsafe, or drifting authority. Live status: **PARTIAL PASS / BLOCKED DOWNSTREAM BY #9068**. The live lane proved #9035 authority reconstruction and socket requalification from an active v4 checkpoint with a pre-existing Ready sandbox; it did not reach the policy boundary, 8/8 completion, chat, completed-resume, or full live acceptance. ## Related Issue Fixes #9035 Parent: #9006 Downstream blocker: #9068 ## Changes - Store checkpoint schema 4 portable intent and secret-free current-user Podman authority, with exact cross-field validation and intentional active schema 1–3 resume refusal. - Pre-read only the resume profile classification, re-read the exact session under the lifecycle lock, permit one bounded race retry, then prepare and requalify portable authority before resumed runtime consumers. - Recompute canonical current-user home, configuration, runtime, socket, and managed configuration settings while rejecting profile, UID, path, type, owner, symlink, endpoint, runtime-kind, or authority drift. - Clear ambient Docker, Podman, XDG, inference, and policy selectors during scoped execution and restore their exact prior presence and values on every return, throw, and handled exit. - Preserve upstream #8992 gateway-database recovery semantics: portable incompatible-state recovery prints the explicit portable `--fresh` command, while default recovery prints `--resume`, in both guidance branches. - Preserve upstream #9075's timeout-argument parsing source, tests, and command reference byte-for-byte while integrating the current `main` history. - Document portable resume, fail-closed recovery, canonical roots, and the active legacy-checkpoint compatibility break. The live resume accepted a reboot-like socket inode rotation while preserving the exact endpoint, owner, mode, immutable authority digest, session identity, Ready sandbox/container identity, and registry identity. After #9035-owned qualification, the run entered #9068's Docker GPU-patch/recreation path and unexpectedly attempted to stop the forward for unrelated sandbox `my-assistant`; that is downstream behavior, not expected or normalized #9035 behavior. The preserved lane was not patched, migrated, retried around the boundary, or claimed as full acceptance. ## Type of Change - [ ] Code change (feature, bug fix, or refactor) - [x] Code change with doc updates - [ ] Doc only (prose changes, no code sample modifications) - [ ] Doc only (includes code sample changes) ## Quality Gates - [x] Tests added or updated for changed behavior - [ ] Existing tests cover changed behavior — justification: - [ ] Tests not applicable — justification: - [x] Docs updated for user-facing behavior changes - [ ] Docs not applicable — justification: - [x] Sensitive paths changed (security, policy, credentials, preflight, onboarding, inference, runner, sandbox, or messaging) - [x] Sensitive-path review completed or maintainer-approved waiver recorded — reviewer/approval link/justification: maintainer task `019f5e28-0f70-7313-92ef-40a3233f796e` approved the schema, lock ordering, environment transaction, security review, scoped live waiver, final diff, and publication. - [ ] Non-success, skipped, or missing CI check accepted by maintainer — check name, approval link, and follow-up issue: ## Documentation Writer Review - [x] Documentation writer subagent reviewed the completed changes - Result: `docs-updated` - Evidence: Independently reviewed signed automatic merge head `52d026093f15dcb75b82c65f61f5ba01c8e63e4e` from #9035 parent `338493906f3ac2abc96e2049b2e124c1314897da` and upstream parent `267abe79856c96fcf74477bd3ce803a942f286fd`.

…9405) <!-- markdownlint-disable MD041 --> ## Summary A gateway database written by a newer OpenShell fails gateway start with one of two sqlx texts. Gateway start explains the `is missing in the resolved migrations` text and prints a named-database recovery, but passes the sibling `has been modified` text through verbatim, so that failure still names no database, no cause, and no remedy. Gateway start now classifies both texts as an incompatible gateway database and prints the same recovery, and the troubleshooting page names both texts. ## Related Issue Refs #9293 This change does not close #9293 on its own, and it intentionally uses no closing keyword. The literal text in that report, `migration 6 was previously applied but is missing in the resolved migrations`, is already classified on `main`: #8995 added `classifyGatewayStartFailure` and #8992 refined it. Neither is contained in `v0.0.103`, the release the reporter read the database with; both first ship in `v0.0.109`. The reported repro therefore no longer produces a raw migration error on a current release, and #9293 can be closed as fixed-in-release independently of this PR. What remains is the sibling signature of the same defect. sqlx `0.8.6` — the version pinned by OpenShell's workspace `Cargo.toml` — reports a database written by a newer OpenShell through two `MigrateError` variants: | Variant | Message | |---|---| | `VersionMissing` | `migration {0} was previously applied but is missing in the resolved migrations` | | `VersionMismatch` | `migration {0} was previously applied but has been modified` | `main` classifies only the first. The second occurs on the same downgrade when the newer OpenShell rewrote an applied migration instead of appending one, and it still reaches the user verbatim. This PR closes that path. ## Changes - `src/lib/validation.ts`: `classifyGatewayStartFailure` matches both sqlx signatures and returns `database_migration_incompatible` for each. The alternation is anchored to the shared `migration N was previously applied` prefix, so `has been modified` alone does not classify. The `GatewayStartFailure` doc names both signatures. - `src/lib/onboard/docker-driver-gateway-failure.ts`: the incompatible-database explanation now reads `The database records a migration that this OpenShell version does not include, or defines with different contents.` so it is accurate for both signatures. No other line of the recovery changes. - `docs/reference/troubleshooting.mdx`: the section covering this failure names both error texts, states what each one means, and is retitled from `Reports a Missing Migration` to `Reports an Incompatible Migration`. No page links to the previous heading. - `src/lib/onboard/gateway-start-failure.test.ts`: a classifier test for the modified-migration text, and a negative guard asserting that `the file containing migration 6 has been modified on disk` stays `unknown`. - `src/lib/onboard/docker-driver-gateway-failure.test.ts`: a reporter test asserting the modified-migration failure names the database file, the cause, and the archive-and-reonboard recovery. ## Type of Change - [ ] Code change (feature, bug fix, or refactor) - [x] Code change with doc updates - [ ] Doc only (prose changes, no code sample modifications) - [ ] Doc only (includes code sample changes) ## Quality Gates - [x] Tests added or updated for changed behavior - [ ] Existing tests cover changed behavior — justification: - [ ] Tests not applicable — justification: - [x] Sensitive paths changed (security, policy, credentials, preflight, onboarding, inference, runner, sandbox, or messaging) - [ ] Sensitive-path review completed or maintainer-approved waiver recorded — reviewer/approval link/justification: requesting maintainer sensitive-path review. As an outside contributor I cannot record a review of my own change. The change adds one alternation to an existing classifier and rewords one printed line; it adds no new command, path, credential handling, or process control, and the recovery command construction and its shell quoting are unchanged from #8995. - [x] Non-success, skipped, or missing CI check accepted by maintainer — check name, approval link, and follow-up issue: ## DGX Station Hardware Evidence - [ ] Tested on DGX Station - Tested commit: - Station profile/scenario: - Result: - Supporting evidence: ## Verification - [x] PR description includes a `Signed-off-by:` line and every commit appears as `Verified` in GitHub - [x] Normal `pre-commit`, `commit-msg`, and `pre-push` hooks passed, or `npm run validate:pr` passed after refreshing `origin/main` when hooks were skipped or unavailable — hooks are not installed in this worktree; `git fetch origin main && npm run validate:pr` passed with zero problems. - [x] Targeted behavior tests pass for the current change set, or tests are marked not applicable above — command/result: `npx vitest run --project cli src/lib/onboard/gateway-start-failure.test.ts src/lib/onboard/docker-driver-gateway-failure.test.ts` → 39 passed, 3 new. Reverting only the two source files to `origin/main` and keeping the tests fails both new positive tests, so they pin the new behavior. `npm run typecheck:cli` → clean. `npx oxlint` on the four changed source files → no findings. `npm run test:changed` was not run to completion on this macOS host; its affected-test selection includes subprocess-spawning lanes that need the GNU utilities described under `macOS Test Dependencies` in `CONTRIBUTING.md`. - [ ] Applicable broad gate passed — `npm test` for broad runtime/test-harness changes; `npm run check` for repo-wide validation/coverage changes — command/result: not run. This change is a focused onboarding diagnostic and adds no runtime or test-harness surface; the targeted CLI tests, `typecheck:cli`, oxlint, `npm run docs`, and `npm run validate:pr` cover the changed contracts. - [x] Quality Gates section completed with required justifications or waivers - [x] No secrets, API keys, or credentials committed - [x] `npm run docs` builds without warnings (doc changes only) — `npm run docs` → `Found 0 errors and 2 warnings`. Both warnings reproduce on the unmodified page set and are unrelated to this change. - [x] Doc pages follow the [style guide](https://github.com/NVIDIA/NemoClaw/blob/main/docs/CONTRIBUTING.md) (doc changes only) - [ ] New doc pages include SPDX header and frontmatter (new pages only) ## Follow-Up Observation Not changed here, and offered only as a question for maintainers: `classifyGatewayStartFailure` has one non-test caller, `reportDockerDriverGatewayStartFailure`. A gateway start that terminates outside that reporter therefore never produces this diagnosis, even when the log carries either migration signature. If that is a gap worth closing rather than intended scoping, I am happy to open a separate issue. --- Signed-off-by: Udaya Tejas <udayatejas2004@gmail.com> <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **Bug Fixes** - Improved detection of incompatible gateway databases when applied migrations are missing or have changed. - Enhanced error messages to explain the issue, identify the database path, and recommend creating an `.incompatible` state directory. - Added clearer handling for migration-related gateway startup failures. - **Documentation** - Expanded troubleshooting guidance to cover both missing and modified migrations. <!-- end of auto-generated comment: release notes by coderabbit.ai --> Signed-off-by: Udaya Tejas <udayatejas2004@gmail.com>

Summary
PR #8995 added an incompatible-database diagnostic for the OpenShell downgrade failure, and gated it on
childExit.exited. A DGX Spark reproduction shows that flag is false on the reported path, so the diagnostic never prints and the user still sees the raw sqlx text.This change prints the diagnosis whenever the classifier matches and hardens the state recovery. A managed gateway stops its owning systemd or Homebrew service in the same command chain as the archive and move. A standalone gateway receives the move only after NemoClaw confirms that no matching gateway process uses the selected state.
Related Issue
Follow-up to #8995, which closed #8797. The failure reported in #8797 still produced no diagnosis before this change.
Changes
printIncompatibleGatewayDatabaseRecoveryfrom the Docker-driver gateway start reporter.The classifier, the archive selection, the shell quoting, and the current-launch log scoping from #8995 are unchanged.
Why the merged diagnostic did not print
startDockerDriverGatewayreports through this reporter in three states: the child exited, the health poll budget expired, and the child's liveness dropped before itsexitevent arrived. The comment atdocker-driver-gateway-failure.tsfor #5334 already records the last two.A gateway that fails this migration check exits during startup, but the reporter is reached through the poll-budget path, so
childExit.exitedis false. Every run in the verification below reported thedid not become healthy within the timeoutline and never thebefore becoming readyline.Type of Change
Quality Gates
The state-move command is the destructive step in the printed guidance. Managed recovery closes the service-restart window by stopping the resolved owner in the same command chain. Standalone recovery fails closed unless the runtime confirms that no matching gateway process uses the selected state. Process IDs are fully validated, commands use trusted argument arrays, archive paths remain shell quoted, and no state move runs automatically.
Documentation Writer Review

It confirmed that the guide distinguishes managed and standalone recovery, names the supported service managers, describes the fail-closed process scan, preserves the credential warning, and matches the command ordering implemented in the reporter.

Step B is the regression this change fixes. Step D confirms the printed recovery.
Steps C and D measured the revision before commit
852421dda9, which answers advisor finding PRA-1 by replacing the user-run check with the liveness probe. That commit changes which guidance step C prints, so the sequence is being re-measured on the same host.Steps B and C apply the change to v0.0.103 because the CLI that reports this failure is always the older release, so a release that pins the newer OpenShell cannot reach the failure.
The step-by-step measurement, including the guard evaluation at step B and a line-level view of the added output, is in this comment.
