fix(cli): detect proxied connect sessions in session reporting

[yanyunl1991]

Summary

Session detection identified a sandbox by its SSH host alias, but newer OpenShell connects every sandbox through one fixed sandbox alias and names the target only on its proxy command. An attached connect session therefore matched nothing, and all three session-reporting surfaces showed no session. Detection now also matches the proxied shape by the sandbox's durable OpenShell ID.

Closes #9316.

Reproduction

Environment

• Test machine: our Ubuntu 24.04 x86_64 test host without a GPU
• Node.js 22.22.2, OpenShell CLI 0.0.101, NemoClaw main at 8cdc3c41e
• Sandbox: OpenClaw with NVIDIA Endpoints

An interactive session was held open with a PTY driver, and the reporting surfaces were read from a separate shell while it was attached.

Before this change

The process is live and requests a TTY:

PID 2647689  ssh -o ProxyCommand=/home/.../openshell ssh-proxy --gateway 'https://127.0.0.1:8080'
             --sandbox-id de7eab7a-002f-41e9-acad-5fd4749e07bb --token ... --gateway-name nemoclaw
             ... -tt -o RequestTTY=force -o SetEnv=TERM=xterm-256color sandbox

Every reporting surface nevertheless showed no session:

parseSshProcesses:            0
nemoclaw <name> status:       SSH sessions: none
nemoclaw list --json:         "activeSessionCount": 0
nemoclaw list:                repro-9302 *          (no active-session dot)

After this change

parseSshProcesses:            1
nemoclaw <name> status:       SSH sessions: 1
nemoclaw list --json:         "activeSessionCount": 1
nemoclaw list:                repro-9302 * ●

After that session detaches, the dashboard forward remains running while all three surfaces return to their empty state:

State	Connect processes	Forward processes	status	list --json	list
Attached, before this change	1	1	none	0	no dot
Attached, after this change	1	1	1	1	●
Detached, after this change	0	1	none	0	no dot

Analysis

parseSshProcesses in src/lib/state/sandbox-session.ts located a sandbox's sessions by scanning process command lines for its SSH host:

const sshHosts = [openshellSandboxSshHost(sandboxName), `openshell-${sandboxName}`] as const;

OpenShell 0.0.101 connects through a proxy instead. The host is the literal sandbox for every sandbox, and --sandbox-id <uuid> inside the ProxyCommand identifies the target. The command line contains no sandbox name, so the host patterns cannot match it.

All three surfaces share this detector: list and list --json use getActiveSessionCount, and <name> status uses printActiveSessions and getActiveSandboxSessions.

The dashboard forward uses the same proxy and sandbox ID. Matching the ID alone would count a session on every Ready sandbox. The interactive session requests a TTY with -tt or RequestTTY=force; the forward runs with -N and no remote command.

Fix

parseSshProcesses accepts an optional durable sandbox ID. When that ID is available, it matches a proxy command carrying the exact ID and requesting a TTY. Existing SSH-host matching is unchanged, including the supported legacy alias.

The OpenShell identity adapter reads and validates the sandbox ID. Session dependencies inject that reader into the parser and contain its cost:

• The lookup runs only when the process list contains --sandbox-id.
• Successful and failed results are cached per sandbox for the life of the command.
• A failed lookup returns null, so list and status retain SSH-host matching instead of failing.

Tests cover parser classification, dashboard-forward exclusion, cross-sandbox isolation, high-level resolver wiring, the host-alias path that must not invoke the resolver, successful memoization, and fail-soft caching.

Changes

• src/lib/adapters/openshell/sandbox-identity.ts: read, validate, and cache durable sandbox IDs behind the OpenShell adapter boundary.
• src/lib/list-command-deps.ts, src/lib/status-command-deps.ts: pass a conditionally resolved sandbox ID through the cached-process-list path.
• src/lib/state/sandbox-session.ts: match proxied interactive sessions by exact sandbox ID and TTY intent while excluding forwards.
• src/lib/adapters/openshell/sandbox-identity.test.ts, src/lib/state/sandbox-session.test.ts: cover parsing, classification, dependency wiring, memoization, and failure handling.

Platform Scope

The issue was reproduced and the change was verified on our Ubuntu 24.04 x86_64 test host. The reporter identified Ubuntu 26.04, Ubuntu 24.04, and DGX Spark. The cause is the OpenShell connection shape rather than host-specific behavior, so the fix applies uniformly; it was not separately run on aarch64.

📝 Walkthrough

Walkthrough

SSH session parsing now detects proxied interactive sessions through durable sandbox IDs. List and status commands resolve IDs only when required. System dependencies memoize successful and failed lookups. Tests cover interactive, forwarding, missing-ID, and mismatched-ID cases.

Changes

Sandbox session detection

Layer / File(s)	Summary
SSH process classification and validation src/lib/state/sandbox-session.ts, src/lib/state/sandbox-session.test.ts	parseSshProcesses accepts an optional sandbox ID, matches proxied interactive TTY sessions, excludes dashboard forwards, and retains legacy host matching. Tests cover matching and rejection cases.
Sandbox-ID resolution src/lib/state/sandbox-session.ts, src/lib/adapters/openshell/sandbox-identity.ts, src/lib/adapters/openshell/sandbox-identity.test.ts	Session detection resolves sandbox IDs only when SSH output contains --sandbox-id. The OpenShell reader invokes openshell sandbox get, parses successful results, memoizes results, and returns null on failures.
Active-session command integration src/lib/list-command-deps.ts, src/lib/status-command-deps.ts, src/lib/state/sandbox-session.test.ts	List and status active-session counting pass the conditionally resolved sandbox ID to parseSshProcesses. Tests verify proxied sessions resolve the ID once and legacy host-alias sessions do not invoke the resolver.

Warnings

Warnings do not block.

PRA-1 Warning — Test command-dependency wiring for proxied session counts

• Location: src/lib/list-command-deps.ts:59
• Category: tests
• Problem: The parser and state-module tests cover durable-ID matching, but no test exercises the new ID-resolution wiring in either list or status command dependencies.
• Impact: A future wiring change can leave list or status reporting zero sessions even when the shared parser correctly recognizes a proxied interactive session.
• Recommendation: Add focused command-dependency tests that provide proxied SSH output and an OpenShell sandbox-ID response, then assert each consumer reports one session and caches the lookup per sandbox.
• Verification: Read the list and status command-dependency tests and confirm they invoke getActiveSessionCount with proxied SSH output, a matching sandbox get response, and the forward-only negative case.
• Test coverage: For list and status command dependencies, simulate a proxied interactive SSH process with a matching sandbox ID and assert activeSessionCount is 1; then retain only a same-ID -N dashboard forward and assert the count is 0.
• Evidence: src/lib/list-command-deps.ts:59-60 passes resolveSandboxIdForSessions into parseSshProcesses. src/lib/status-command-deps.ts:267-268 contains the equivalent changed wiring. src/lib/status-command-deps.test.ts:15-121 tests other dependencies and has no proxied session-count case. No list command dependency test file was found in the reviewed source tree.

Security Code Review

Verdict

PASS. I reviewed the complete change at b6e52059b. It attributes proxied interactive SSH processes only after an exact, validated sandbox-ID match and a TTY-intent check, preserves existing host-alias matching, excludes dashboard forwards, and fails soft when OpenShell identity lookup is unavailable. I found no security findings.

Findings

None.

Detailed Analysis

1. Secrets and Credentials — PASS. Process lines can contain an OpenShell token, but the change neither extracts nor logs it. It reads only the exact sandbox ID and TTY intent. Tests contain only a placeholder token.
2. Input Validation and Data Sanitization — PASS. OpenShell IDs must match the existing canonical character allowlist. Both sandbox IDs and sandbox names are escaped before regular-expression construction, and the ID match requires a complete token boundary.
3. Authentication and Authorization — PASS. No authentication, authorization, identity, or access-control policy changes.
4. Dependencies and Third-Party Libraries — PASS. No dependency, package, image, or third-party code changes.
5. Error Handling and Logging — PASS. Nonzero, malformed, ambiguous, or thrown identity lookups return null and are cached as unavailable. Reporting remains usable through existing host-alias detection without printing command output.
6. Cryptography and Data Protection — PASS. No cryptographic, transport-security, or protected-data behavior changes.
7. Configuration and Security Headers — PASS. No network policy, environment configuration, or security-header changes. The lookup uses the already resolved OpenShell executable and a fixed argument vector.
8. Security Testing — PASS. Tests cover exact and mismatched IDs, missing IDs, forward exclusion, high-level resolver wiring, host-alias bypass, successful memoization, and fail-soft caching. The affected-test run passed 42/42, and repository hooks passed.
9. System Security — PASS. The host-boundary call is isolated in the OpenShell adapter, uses argument-array execution without a shell, has a five-second timeout, and performs no filesystem, privilege, container, or runtime-resource mutation.
