Status: proposed; not implemented. +Baseline: `main` at `a55c5f5d`, after terminal sessions (#328), terminal exec +(#319), and node-to-node archive transfer (#317). + +This is the implementation handoff and security design for the feature. Public +user procedures belong in `apps/docs/content/docs/` when the feature ships. +Historical specs describe earlier decisions; this document changes the terminal +execution and agent-access decisions explicitly. It does not claim those changes +already exist. + +## 1. Outcome and settled scope + +An agent running in Subshell can operate a Linux or macOS destination over SSH +without installing Subshell or an agent CLI there. A human configures a private +connection, grants selected agent panes access, inspects results, and can take +control of an interactive terminal. + +V1 includes saved connections through existing nodes, existing SSH keys and +certificates, connection testing, structured commands, incremental output, +cancellation, and interactive terminals in the server SPA. The same SPA serves +browser and desktop-client users; this requires no new privileged command in the +desktop window that displays the control plane. + +Decisions confirmed by the user: + +- Reuse credentials on the connecting node; do not build credential storage. +- Keep connections private in v1. +- Support Linux/macOS destinations and POSIX command syntax first. +- Put remote file operations in the next milestone. +- Require human-issued grants for individual agent panes and connections. +- Require key-based authentication in v1. Passwords, MFA entry, key unlocking, + and host-trust setup occur outside Subshell on the connecting node. + +Also deferred: Windows destinations, connection sharing, persistent remote +sessions, remote agent launch, and conversation handoff. Ordinary interactive +applications remain possible, but a terminal is not a private secret-entry form. + +Codex provides the UX reference: discover SSH hosts and select a remote project. +Its documented workflow requires Codex installed and authenticated remotely; +this design keeps the agent on an existing node instead. See the +[official SSH workflow](https://learn.chatgpt.com/docs/remote-connections#connect-to-an-ssh-host). + +### Existing features to keep + +Keep the terminal plugin, presetless terminal launches, `create_subshell.harness`, +catalog entries in `list_presets`, byte-cursor log reads, raw input, lifecycle +tools, encrypted agent channels, and enrolled-node `transfer_files`. The harness +field and catalog now serve presetless terminal discovery; earlier suggestions +to remove them no longer apply. + +Rename the visible "Cross-agent comms" grouping to **Agent-created**. Keep its +provenance flag, silent creation, and cleanup responsibility. No database-column +rename is required. Correct MCP instructions that describe every pane as an +agent. The obsolete preset-name launch instruction was already fixed on main. + +## 2. Security model and required protections + +The existing [security model](docs/security.md) is the baseline. The controls +below protect Subshell APIs; they do not sandbox a process that already runs as +the connecting OS account. Such a process may independently run SSH or read that +account's files. Compromised OS accounts, malicious administrators, and a +compromised control plane remain outside the existing trust boundary. + +The destination account determines command permissions. A remote working +directory is not a filesystem restriction. Arbitrary remote shell access also +permits network access and privilege use available to that account. + +| Design risk | Required mitigation | +| --- | --- | +| Every existing agent silently gains access to SSH credentials | Explicit SSH token permission plus a human-issued per-pane, per-connection grant; no legacy permission fallback | +| Generic pane APIs bypass connection permissions | One SSH authorization policy used by all REST, WebSocket, preview, log, lifecycle, and sharing surfaces | +| Human takeover is mistaken for confidential input | State that takeover controls input, not historical secrecy; defer in-app SSH secret entry | +| SSH config starts local helpers, forwards ports, or reuses ambient connections | Human-only resolution followed by an approved normalized configuration and mandatory runtime restrictions | +| Commands are repeated after an ambiguous disconnect | Durable acceptance before spawn, request binding, reconciliation, and no automatic replay | +| A quiet pane is mistaken for an idle shell | Keep terminal exec explicitly heuristic; use supervised SSH processes for structured commands | +| Output floods memory or disk | Bound accumulation, reads, retention, concurrency, and aggregate storage; drain excess output | +| Remote output impersonates trusted UI | Render output as data and keep authoritative identity/control outside terminal text | + +### Ownership and explicit grants + +A connection is a resource, not an enrolled node. Only the node owner may +configure connections through an enrolled node. An administrator may configure a +private connection through the server's built-in node, subject to its existing +launch-enabled and maintenance rules. Admin status does not bypass those rules +or grant API access to another user's private connection. + +Human configuration, discovery, grants, and control changes require a cookie +session. Validate request origin/CSRF on these writes explicitly; do not assume +cookie authentication alone is sufficient. Machine credentials cannot call them. + +A grant binds a connection revision to a pane ID and its current credential +generation (the issued API-key identity). It records the granting human and +revocation state. It permits that pane to read/use that connection, not configure +it. Both a coarse `ssh` permission and this row-level grant are required. Old +tokens receive no grandfathering; a human can restart a pane to obtain a current +token and then grant it access. Child panes and restarted panes inherit nothing. + +MCP lists only the connections granted to the caller. Every operation rechecks +the token, pane lifecycle, owner, grant, connection revision, and node eligibility. +Inaccessible resource IDs use the existing non-enumerating 404 convention. + +### Generic pane surfaces and revocation + +Managed SSH panes remain private even though their rendering and lifecycle reuse +ordinary panes. Gate list previews, detail reads, logs, captures, live updates, +attach-token minting and redemption, input, exec, prompt injection, restart, +termination, deletion, and sharing through the connection policy. Sharing SSH +panes is refused in v1. Same-owner sibling panes need their own grants. + +Do not mint MCP credentials or inject Subshell credentials into SSH processes. +Existing machine-minted attach tokens retain their caller identity and are +rechecked against SSH grants and control state when redeemed. Active subscriptions +must also be closed or filtered when permission/control changes. + +Revocation prevents new dispatch, rejects queued input, closes affected streams, +and cancels runs/terminals initiated under that grant where reachable. Human-owned +sessions and work initiated under other valid grants are not cancelled. Bind each +resource to its initiating grant/credential so this distinction is enforceable. +Offline cancellation stays pending and is dispatched before new work on reconnect. +Terminating SSH never guarantees remote descendants died. + +### Authentication and trust + +All managed SSH invocations use noninteractive key/certificate authentication, +including interactive shell sessions. An already-unlocked authentication agent +may be used. Password, MFA, key-unlock, and unknown-host requirements produce +actionable instructions to configure the connecting account outside Subshell. +There is no host-key acceptance endpoint in v1. + +Require existing verified host trust. Unknown, changed, and revoked keys fail +closed. Keep certificate/revocation checks and secure algorithm defaults. A key +scan is not identity verification and must never become an automatic trust step. + +### Configuration is executable, not passive data + +OpenSSH supports local helper execution, forwarding, and multiplexed connections; +see the [OpenSSH configuration reference](https://man.openbsd.org/ssh_config). +Discover aliases by bounded parsing of the account's config and includes; omit +wildcard-only entries, detect include cycles, and allow manual aliases. Discovery +returns names, not config file contents. Resolution/testing is a human action and +must disclose that trusted configuration such as `Match exec` can run locally. + +Persist an approved normalized snapshot after resolution. Agent requests accept +only connection IDs, never raw hosts, usernames, ports, SSH options, environment +overrides, config paths, or proxy commands. Render runtime config from an explicit +allowlist; do not let runtime SSH reread ambient user/system configuration. + +Supported resolved settings are destination host/user/port, identity and +certificate references, authentication-agent reference, host-trust references +and host-key alias, and a bounded `ProxyJump` chain. Normalize every hop under the +same restrictions. Preserve referenced trust files and their revocation/CA +semantics. Defer arbitrary `ProxyCommand`, dynamic known-host commands, provider +commands, and other required settings that cannot be represented safely; refuse +with a named limitation rather than silently changing connection semantics. + +Mandatory runtime policy applies to every hop: strict host checking, no +agent/X11 forwarding, no configured local/remote/dynamic forwards or tunnels, no +local commands or SSH escape commands, and no ambient control sockets or +multiplexing. Do not import `RemoteCommand`, `SendEnv`, or `SetEnv`. Unsupported +client options fail setup rather than silently omitting a protection. Validate +this policy on supported Linux and macOS OpenSSH versions. + +Configuration edits create a new revision and invalidate grants. Refuse edits +while work is active; the human must stop or finish it first. Trusted local OS +changes to referenced keys/trust files remain inside the OS trust boundary. + +Spawn using explicit argv and a minimal environment: no app secrets, Subshell +credentials, preset environment, loader overrides, shell startup overrides, or +askpass hooks. Allow an authentication-agent socket only from trusted connecting +account setup. Reject option-like aliases/control characters; quote remote +directory arguments as POSIX data. Only `command` is intentional shell code. + +## 3. Product behavior and execution contracts + +### Connection UI + +Add **SSH connections** to user settings: select connecting node, choose/enter +alias, review resolved destination and connecting OS account, set optional +absolute remote directory, test, save, then grant selected panes separately. + +Always show the route, for example **Staging · deploy@app-02 · via Laptop**. +Distinguish remote paths from connecting-node paths. Remote OSC titles cannot +replace the trusted destination label. Show connecting-node unavailability +separately from destination/authentication errors. File uploads to SSH terminals +are disabled until remote file operations exist. + +### Structured commands + +Path: SPA/MCP → server authorization → signed/encrypted node command → shared SSH +runtime → destination. The server-hosted node uses the same runtime directly. + +Each command uses a supervised non-PTY SSH process and independent shell context. +Directory/environment mutations do not persist between commands. Keep stdout and +stderr separate. A failed directory change must prevent command execution. +Structured commands do not scrape interactive shell prompts or completion markers. + +Start returns a run ID promptly. Read returns bounded incremental output and +status; browser closure or read timeout does not cancel execution. Connection +testing uses a fixed benign probe, not caller-supplied command text. + +Use lifecycle states `accepted`, `running`, `completed`, and `unknown`, plus +separate cancellation/deadline facts. `completed` carries an observed remote exit +status; unknown must not masquerade as failed or successful. Retain local SSH +exit/signal information separately. OpenSSH's 255 status is ambiguous between +transport error and remote status; do not claim a confirmed remote result from +that number alone. See [SSH exit status](https://man.openbsd.org/ssh#EXIT_STATUS). + +Cancellation stops locally supervised SSH/helper processes with a bounded grace +period. Report remote termination as unconfirmed. Commands can daemonize or +otherwise survive the connection; no UI label should imply otherwise. + +### Durable dispatch and storage + +Allocate run IDs server-side and bind them to owner, initiating grant/credential, +connection revision, and a digest of the complete request. The connecting runtime +durably records acceptance before spawning. Duplicate delivery returns existing +state; a different payload under the same ID is refused. A crash between acceptance +and spawn produces unknown state, not automatic permission to try again. + +Reconcile known IDs after reconnect. Unknown or expired IDs are not reusable start +requests. Persist deduplication records for the full accepted-request lifetime; +deleting output must not delete replay protection. Validate signed command expiry +and reject stale starts after reconnect. Do not queue new execution while offline. + +Use opaque IDs for filesystem names, 0700 directories, and 0600 files. Refuse +symlinks/path escapes during creation, reads, and cleanup. Store output on the +connecting runtime and relay it through authorized reads; the server stores run +metadata, not a second unbounded output copy. + +| Limit | Default | +| --- | --- | +| Execution deadline | 5 minutes, caller-selectable up to 1 hour | +| Active structured runs | 4 per owner per connecting node; 16 total per connecting node | +| SSH terminals | 4 per owner per connecting node | +| Retained output per structured run | 10 MiB combined stdout/stderr | +| Aggregate SSH output storage | 1 GiB per connecting node, including managed SSH terminal logs | +| Completed-run retention | 7 days | +| Output response window | At most 256 KiB | +| Read long poll | At most 30 seconds | +| Connection/setup probe | 30-second overall deadline, no automatic execution retry | + +Bound partial lines, pending buffers, and in-flight responses. Keep draining after +capture limits and report truncation. Under disk pressure evict completed output +first; if still full, reject new work. Active SSH terminal logs need bounded +rotation with an explicit cursor-expired/reset result, never silent cursor reuse. +Use log generation plus byte offset where rotation occurs. Do not silently change +the existing non-SSH byte-cursor contract. + +Command text and output can contain secrets: keep them out of operational logs, +audit metadata, and notifications. Audit actor/resource IDs, connection revisions, +grant/control changes, destinations, and lifecycle outcomes. Render output as +text/xterm data, never HTML. No automatic link opening or clipboard access; retain +explicit human clipboard interaction. + +### Interactive terminals and input control + +Reuse rendering, geometry, short-lived attach tokens, and pane lifecycle. SSH is +the foreground process; its exit ends the pane with no connecting-node shell +fallback. Restart creates a new SSH session and rechecks authorization. Neither +local tmux nor an SSH reconnect guarantees remote-session persistence. + +Human-opened terminals start in human control; agent-opened ones start in agent +control. Humans can take over immediately. Only humans return control to agents. +Human mode blocks agent reads and writes on every API/stream, but recorded output +can become visible after return to agent control. Explain that ordinary terminal +history is not confidential secret storage. + +### Existing `exec_in_terminal` + +Keep its combined-output, POSIX-marker contract as a terminal convenience. Add +execution IDs, persistent outstanding state, and a read-only status operation. +Enforce input ownership across every write path, including restart prompts and +nudges. A caller's wait timeout leaves the reservation active; continue bounded +marker observation. A late marker can complete it; lost observation/restart makes +it unknown. An explicit human takeover invalidates the result and fences stale +queued input using the node-enforced input generation. + +Quiet output is only a heuristic; it cannot detect a silent program waiting on +stdin. Document unsupported interactive commands/shell syntax clearly and never +upgrade marker text into a security decision. Do not use this helper on managed +SSH terminals. Keep its report-only timeout behavior: no automatic Ctrl-C. +After observation becomes unknown, refuse further automated exec until human +recovery or pane restart; do not monitor or reserve unbounded memory indefinitely. + +## 4. Shared interfaces and compatibility + +These contracts must be landed by workstream A before parallel implementation. +Agents may not invent incompatible alternate shapes in their own modules. + +### Persistence + +- Connections: owner, connecting node, display name, normalized config snapshot, + remote-directory default, revision, and timestamps; no credential contents. +- Grants: connection revision, pane ID, API-key identity, human grantor, timestamps, + and revocation; unique active binding for that tuple. +- SSH runs: run ID, connection snapshot/revision, owner, initiating grant/credential, + request digest, lifecycle/cancellation facts, observation and exit information. +- Pane association: SSH connection revision, initiator, control owner/generation, + and log generation; no implicit grants via ordinary pane ownership. +- Terminal exec records: execution ID, pane incarnation, initiator, input generation, + observation state, and bounded-result metadata. + +Register migrations in both the migration directory and static boot provider. +Connection deletion is refused while work is active. Retained run history keeps +an immutable destination snapshot after the connection is deleted. + +### REST and MCP surface + +REST uses camelCase bodies and the existing authenticated service pattern. Define +schemas once server-side and validate all node wire responses with shared parsers. + +| REST family | Capability | Caller | +| --- | --- | --- | +| `/api/ssh/discovery` | List aliases on a selected eligible node | Human cookie only | +| `/api/ssh/connections` | CRUD and fixed connection test | Human cookie for writes; granted pane for filtered reads | +| `/api/ssh/connections/:id/grants` | Grant/revoke individual pane access | Owning human cookie only | +| `/api/ssh/runs` | Start, get/read output, request cancellation | Owning human or explicitly granted pane | +| `/api/ssh/terminals` | Create managed SSH pane | Owning human or explicitly granted pane | +| Existing pane routes plus control/status operations | Attach/input/lifecycle, human takeover/return, terminal exec status | Shared pane + SSH policy where applicable | + +No trust-acceptance, credential-upload, arbitrary-option, or arbitrary-host API. +Run/terminal IDs are scoped by authorization, never bearer capabilities themselves. + +MCP adds `list_ssh_connections`, `execute_ssh_command`, `read_ssh_command`, +`cancel_ssh_command`, and `open_ssh_terminal`, plus `get_terminal_execution` for +recovering an existing `exec_in_terminal` result. Existing pane tools operate SSH +terminals through the additional policy; do not add duplicate SSH input/log tools. + +Node wire commands cover human config discovery/resolution, test, run start/status/ +read/cancel, SSH terminal launch, and input-control generation transitions. Reuse +the existing encrypted/signed command transport and exact protocol version policy. +The baseline is protocol 15; the coordinator selects the next unused version at +integration and performs one coordinated bump for these changes. No capability +negotiation or old-node fallback. Short RPCs start work; long tasks are not held +inside the existing RPC response deadline. + +The shared runtime lives in the permissive packages; server repositories and +authorization stay under `apps/server/`. Do not move AGPL implementation into +packages or introduce runtime imports from Apache packages into server code. + +## 5. Multi-agent work breakdown + +This section authorizes a future implementation coordinator to delegate the work. +Writing this plan does not start implementation or authorize a release. +Use at most three workers alongside the coordinator in a four-slot session. +Read each app's `AGENTS.md` before its code and the relevant rules/deep dives. + +### Ownership and handoff rules + +- Assign one owner to each shared file. Do not concurrently edit a registry, + migration provider, barrel, manifest, lockfile, or central service. +- Workers own their modules and tests. They return exact integration changes for + coordinator-owned files instead of editing those files opportunistically. +- Coordinator owns `SSH-SUPPORT.md`, shared protocol/error contracts, root/package + dependency edits, migration numbering/provider, central route registration, + central auth/token wiring, launcher integration, and protocol version bump. +- Workstream C owns `subshells.service.ts` and generic pane/WS authorization edits; + workstream D calls C's policy interface rather than also editing those files. +- Workstream E owns `packages/mcp-core/src/server.ts` and MCP registration. UI + workers do not edit that registry. +- Use separate worktrees when available. Otherwise use the exclusive file map + below and report collisions before editing. Do not reset another agent's work. +- A worker handoff includes changed files, contracts consumed/provided, tests and + captured results, known limitations, and unresolved integration issues. +- Tests passing inside one workstream do not establish integrated security. + +### Workstreams + +| ID / agent | Ownership | Deliverables and acceptance | Dependencies | +| --- | --- | --- | --- | +| A — coordinator/contracts | Shared protocol/types/errors, integration registries, migration allocation, this plan | Freeze request/result and authorization/control contracts; define test fixtures; coordinated protocol bump; no ambiguous ownership | First | +| B — SSH runtime | New `packages/pane-runtime/src/ssh/` modules and node SSH command handlers/tests | Normalized safe config, all-hop policy, probes, supervised runs, durable deduplication, bounded storage, cancellation; real isolated sshd tests | A | +| C — pane control | Terminal execution service, generic pane routes/WS gates, input generation plumbing and tests | All writers fenced; timeout/late completion/restart recovery; comprehensive SSH gate hook; no fallback local shell; bounded SSH terminal history | A; B for final SSH lifecycle integration | +| D — SSH backend | New server SSH repositories, services, API schemas/routes and tests | Connection revisions, grants, runs, authorization, revocation/reconciliation, audit/retention orchestration; deny-by-default policy implementation | A; B for runtime adapters; C for pane hooks | +| E — MCP | `packages/mcp-core` tools, registration, instructions and tests | New tools, honest errors/results, explicit grants, status recovery, no automatic retries, existing-tool compatibility | A and frozen D/C APIs | +| F — SPA | New SSH settings/hooks/views and existing terminal control UI/tests | Human setup/grants, clear route identity, error states, run output, takeover, private SSH panes, no uploads/auth-secret forms | A and frozen D/C APIs | +| G — verification/docs | Isolated e2e SSH fixtures, adversarial integration tests, public docs/security updates | Cross-path bypass/race coverage, compiled smoke tests, security accounting, acceptance evidence | Can prepare fixtures after A; final execution after B–F | + +### Scheduling with four slots + +1. **Gate A: contracts.** Coordinator lands shared shapes and ownership assignments. + Workers may inspect and prepare fixtures, but do not build against guessed APIs. +2. **Wave 1: B + C + D.** Runtime, pane control, and backend proceed concurrently + using contract fixtures. Coordinator integrates shared files and resolves + disagreements without weakening authorization or failure semantics. +3. **Gate B: backend integration.** Demonstrate one authorized command, a denied + ungranted pane, durable duplicate rejection, and takeover fencing using real + SSH fixtures. Incomplete security paths remain unreachable from public APIs. +4. **Wave 2: E + F + G.** MCP and SPA implement the frozen integrated API while + verification exercises it independently. Runtime/backend owners are recalled + as needed for focused fixes, within the concurrency limit. +5. **Gate C: end-to-end security review.** Coordinator and verifier audit the full + authorization matrix, races, resource bounds, protocol behavior, and docs. + Integrate fixes and rerun affected checks, then complete the release checklist. + +Do not ship partially wired generic pane access while SSH gates are still stubs. +Do not merge a placeholder authorization helper that returns success. Refusals are +the default until the full policy is installed. + +### Copyable assignment template + +> Implement workstream [ID] from SSH-SUPPORT.md. Read its dependencies and relevant +> app instructions first. Edit only assigned files; coordinator-owned integration +> files require a handoff request. Preserve the settled security and scope decisions. +> Add the specified tests, capture one run's output, and report changed files, +> integration needs, results, and limitations. Do not publish, release, touch the +> live instance, or change another worker's files. Escalate contract conflicts to +> the coordinator rather than adding fallback behavior. + +## 6. Verification and completion gates + +Use an isolated SSH fixture with temporary accounts, keys, trust files, and config. +Never use the live instance or a developer's SSH configuration. Bind test services +to loopback, track their processes, and clean up only resources the fixture owns. +Read `e2e/AGENTS.md` before adding browser/stack coverage. + +### Security acceptance matrix + +| Area | Required cases | +| --- | --- | +| Grants | Wrong owner, same-owner ungranted pane, child/restarted pane, old token, revoked token, changed revision, disabled account | +| Alternate paths | Generic list/detail previews, logs, captures, live updates, attach mint/redeem, input, prompts, restart/terminate/delete, sharing | +| Races | Revoke or takeover against queued input, dispatch, token redemption, active streams, offline cancellation, and reconnect | +| SSH policy | Unknown/changed/revoked keys, certificates, config includes, jump hosts, ambient forwards, control sockets, proxy/local commands, askpass, SendEnv/SetEnv | +| Injection | Option-like aliases, control characters, quoted directories, shell metacharacters as data, symlink/path escapes in runtime storage | +| Execution | Duplicate IDs/payload mismatch, crash before/after spawn, ambiguous acknowledgement, exit 255, timeout, cancellation, no automatic replay | +| Resource limits | Infinite output, oversized partial line, stalled client, quota exhaustion, excessive concurrent starts/probes, bounded log rotation | +| Terminal control | Every input writer, stale generation, late marker, restart recovery, human takeover, no local-shell fallback, no secret-privacy claims | +| Untrusted output | HTML/ANSI/OSC, clipboard requests, malicious links/titles, spoofed completion; identity and permissions remain authoritative | +| Compatibility | Existing terminals/presets/cursors/transfers, protocol mismatch, static migration registration, compiled CLIs, licence checks | + +Run affected package `test` scripts with `env -u SHELLOPTS -u BASHOPTS`; capture +output once and inspect failures from the file. Focused single-file runs are fine +while editing. Run type checking and relevant lint/design/license checks, then +isolated e2e and compiled-binary smoke tests. No Rust change is anticipated; if +scope introduces one, run the repository Rust checks too. Do not use live :3080. + +Final documentation work updates public SSH/MCP guidance, app routing notes, and +security accounting. Use changesets for the server and node apps and docs when +applicable; the server ships SPA changes. Do not hand-edit changelogs or write +changesets for ignored packages. Read `docs/release-and-ci.md` before artifact or +release work; releases remain separately authorized workflow actions. + +### Definition of done + +- A human can save a supported SSH connection and grant one live agent pane access. +- That pane can run a command, recover its result by ID, and open an SSH terminal. +- An ungranted pane cannot use generic APIs to recover the same access. +- Human takeover and revocation fence subsequent input and streams at every path. +- SSH credentials remain on the connecting account; no in-app secret entry or trust bypass exists. +- Disconnects and crashes never cause command replay or false success reports. +- Runtime/output resources are bounded and cleanup is safe. +- Existing MCP terminal and node-transfer workflows still pass their tests. +- Security verification evidence is recorded; no tests or implementation touched the live instance. + +## 7. Follow-up milestones + +Remote browsing, transfers, and structured file edits come next. Reuse existing +transfer semantics where appropriate, but node archive commands require enrolled +nodes and cannot operate an ordinary SSH destination directly. Design the SSH +transport and authorization before extending `transfer_files`. + +Persistent remote sessions, connection sharing, private authentication flows, +Windows support, remote agent launch, and conversation handoff each need explicit +designs. Do not smuggle them into v1 through arbitrary SSH options or shell wrappers.

Shared fixtures for the four parallel workers. --- .../__tests__/backup-cli-subprocess.test.ts | 29 +- apps/server/api/src/db/migrate.ts | 7 + .../src/db/migrations/0047-ssh-connections.ts | 100 ++++ .../src/db/migrations/0048-ssh-execution.ts | 137 +++++ .../__tests__/0047-ssh-connections.test.ts | 162 ++++++ .../__tests__/0048-ssh-execution.test.ts | 272 +++++++++ apps/server/api/src/db/types/index.ts | 17 + .../server/api/src/db/types/ssh-actor-side.ts | 11 + .../src/db/types/ssh-connections.db-types.ts | 44 ++ .../db/types/ssh-exec-observation-state.ts | 17 + .../api/src/db/types/ssh-grants.db-types.ts | 46 ++ .../api/src/db/types/ssh-panes.db-types.ts | 61 ++ .../api/src/db/types/ssh-runs.db-types.ts | 119 ++++ .../db/types/ssh-terminal-execs.db-types.ts | 79 +++ .../api/src/services/backups/database.ts | 2 +- .../api/src/services/backups/metadata.ts | 91 ++- .../api/src/services/ssh/ssh-api-types.ts | 399 +++++++++++++ .../server/api/src/services/ssh/ssh-policy.ts | 254 ++++++++ .../src/__tests__/fixtures/ssh-fixtures.ts | 328 +++++++++++ .../src/__tests__/ssh-config.test.ts | 82 +++ .../src/__tests__/ssh-frames.test.ts | 301 ++++++++++ packages/subshell-protocol/src/index.ts | 68 +++ packages/subshell-protocol/src/node-frames.ts | 52 +- .../subshell-protocol/src/node-results.ts | 140 ++++- packages/subshell-protocol/src/ssh-config.ts | 246 ++++++++ packages/subshell-protocol/src/ssh-errors.ts | 102 ++++ packages/subshell-protocol/src/ssh-frames.ts | 548 ++++++++++++++++++ packages/subshell-protocol/src/ssh-limits.ts | 121 ++++ 28 files changed, 3806 insertions(+), 29 deletions(-) create mode 100644 apps/server/api/src/db/migrations/0047-ssh-connections.ts create mode 100644 apps/server/api/src/db/migrations/0048-ssh-execution.ts create mode 100644 apps/server/api/src/db/migrations/__tests__/0047-ssh-connections.test.ts create mode 100644 apps/server/api/src/db/migrations/__tests__/0048-ssh-execution.test.ts create mode 100644 apps/server/api/src/db/types/ssh-actor-side.ts create mode 100644 apps/server/api/src/db/types/ssh-connections.db-types.ts create mode 100644 apps/server/api/src/db/types/ssh-exec-observation-state.ts create mode 100644 apps/server/api/src/db/types/ssh-grants.db-types.ts create mode 100644 apps/server/api/src/db/types/ssh-panes.db-types.ts create mode 100644 apps/server/api/src/db/types/ssh-runs.db-types.ts create mode 100644 apps/server/api/src/db/types/ssh-terminal-execs.db-types.ts create mode 100644 apps/server/api/src/services/ssh/ssh-api-types.ts create mode 100644 apps/server/api/src/services/ssh/ssh-policy.ts create mode 100644 packages/subshell-protocol/src/__tests__/fixtures/ssh-fixtures.ts create mode 100644 packages/subshell-protocol/src/__tests__/ssh-config.test.ts create mode 100644 packages/subshell-protocol/src/__tests__/ssh-frames.test.ts create mode 100644 packages/subshell-protocol/src/ssh-config.ts create mode 100644 packages/subshell-protocol/src/ssh-errors.ts create mode 100644 packages/subshell-protocol/src/ssh-frames.ts create mode 100644 packages/subshell-protocol/src/ssh-limits.ts diff --git a/apps/server/api/src/commands/__tests__/backup-cli-subprocess.test.ts b/apps/server/api/src/commands/__tests__/backup-cli-subprocess.test.ts index 9f1bb6dae..e848fc059 100644 --- a/apps/server/api/src/commands/__tests__/backup-cli-subprocess.test.ts +++ b/apps/server/api/src/commands/__tests__/backup-cli-subprocess.test.ts @@ -388,16 +388,25 @@ test("real entry: available older upgrade snapshot restores and migrates before mkdirSync(backupDir, { mode: 0o700 }); const snapshot = join(backupDir, "subshell-v1.7.0-20260101-000000.db"); const db = new Database(instance.databasePath); - const migration = db.query("SELECT * FROM kysely_migration WHERE name='0046-backup-recovery'").get() as { + // The anchor is the CURRENT last migration (0048-ssh-execution as of the + // SSH Gate A landing).

route passes the seed - ssh-surface-census test pins every frozen surface to a production call site (attach_mint documented as coordinator ruling; ws-token hunk withdrawn) - live-publisher asks the policy for `live` (owner seed) instead of narrowing structurally; admin-owned managed panes now receive frames, other-user managed panes stay admin-silent - redeem seeds the pane's bound apiKeyId (system-key mint's key documented unknowable); nudge refuses managed panes at the plane;

Refusals render the protocol package's shipped SSH_ERROR_DESCRIPTIONS sentences by code equality. Also the SS1 copy change: the rail's "Cross-agent comms" grouping is now "Agent-created" (label and pane-header text; provenance flag and behavior unchanged; mcp-core strings belong to workstream E).

Revoking does not touch work you started yourself or work running under another grant. + +An ungranted pane cannot reach a connection through any side door either. Generic pane surfaces (lists, previews, logs, live terminal views, attach tokens, input, exec, prompts, restart, terminate, delete, sharing) all ask the same SSH policy, and a pane without a grant sees a managed SSH terminal as if it did not exist. + +## What an agent can do + +With a grant, a pane can: + +- List the connections granted to it. +- Run a structured command, read its incremental output, and cancel it.

the protocol parser pins the optional positive-integer shape; an ordinary read stays field-free even against a node echoing one. --- .../agent/src/__tests__/commands-ssh.test.ts | 42 +++++++ apps/node/agent/src/commands/tail.ts | 17 ++- .../__tests__/ssh-pane-gates.test.ts | 118 +++++++++++++++++- .../server/api/src/services/nodes/log-tail.ts | 38 ++++-- .../api/src/services/nodes/node-launcher.ts | 2 +- .../api/src/services/nodes/remote-launcher.ts | 14 ++- .../src/services/ssh/ssh-panes.repository.ts | 19 +++ .../src/services/subshell-manager.service.ts | 2 +- .../api/src/services/subshells.service.ts | 36 +++++- .../src/__tests__/node-results.test.ts | 7 ++ .../subshell-protocol/src/node-results.ts | 18 ++- 11 files changed, 287 insertions(+), 26 deletions(-) diff --git a/apps/node/agent/src/__tests__/commands-ssh.test.ts b/apps/node/agent/src/__tests__/commands-ssh.test.ts index 83fa288b1..b4f30dfa7 100644 --- a/apps/node/agent/src/__tests__/commands-ssh.test.ts +++ b/apps/node/agent/src/__tests__/commands-ssh.test.ts @@ -2,11 +2,13 @@ import { afterAll, beforeAll, describe, expect, it } from "bun:test";

On a managed pane the node's fence store refused every such frame (a record exists, the frame carries no generation), which is fail-safe but dead: the flagship human-takeover act could not type. The keystroke path now runs the SSH-SUPPORT.md 2 "every input writer" rule: ONE primary-key read on ssh_panes decides the seam. A managed pane rides the same generation-stamped sendManagedInput hook as the REST input route (stamp read fresh per frame; a failed write is dropped, never entered into the Wave D hold - a hold re-fires through the ordinary unstamped seam, which is exactly the bypass). An ordinary pane takes the untouched launcher path: byte-identical bytes and acks, no hook, one PK read its only new cost. The keystroke-writer cover joins the 6 matrix (managed frames reach the node WITH the stamp; stale is refused; ordinary stays hook-free). --- .../api/src/ws/__tests__/input-hold.test.ts | 10 +- .../api/src/ws/__tests__/subshell-ws.test.ts | 244 +++++++++++++++++- apps/server/api/src/ws/subshell-ws.ts | 231 +++++++++++------ 3 files changed, 396 insertions(+), 89 deletions(-) diff --git a/apps/server/api/src/ws/__tests__/input-hold.test.ts b/apps/server/api/src/ws/__tests__/input-hold.test.ts index 57d4a575b..cfbbc965a 100644 --- a/apps/server/api/src/ws/__tests__/input-hold.test.ts +++ b/apps/server/api/src/ws/__tests__/input-hold.test.ts @@ -1,4 +1,5 @@ -import { describe, expect, it } from "bun:test";

MINOR 6: the per-owner run quota was check-then-act (two counts, then a plain insert), so concurrent starts could transiently exceed 4. The count and the insertion are one unit now (SshRunsRepository .createGuardedByQuota, the db.transaction precedent whose measured dialect property - bun:sqlite synchronous over one shared connection - is what makes it sufficient); the node's serialized 16 stays the hard cap. The races suite fires six concurrent starts on a fresh (owner, node) pair: exactly 4 rows, exactly 4 wire frames, 2 named quota_runs refusals. MINOR 5: the surface census still listed attach_mint as PENDING while api/ws-token.route.ts had long since wired it; the file joins PRODUCTION_SOURCES and PENDING_WIRING is empty, so the census catches real removals again instead of an outdated excuse. --- .../__tests__/ssh-adversarial-races.test.ts | 54 +++++++++++++++ .../__tests__/ssh-surface-census.test.ts | 35 +++++----- .../src/services/ssh/ssh-runs.repository.ts | 46 +++++++++++++ .../api/src/services/ssh/ssh-runs.service.ts | 69 +++++++++---------- .../api/src/services/subshells.service.ts | 12 ++++ 5 files changed, 164 insertions(+), 52 deletions(-) diff --git a/apps/server/api/src/api/ssh/__tests__/ssh-adversarial-races.test.ts b/apps/server/api/src/api/ssh/__tests__/ssh-adversarial-races.test.ts index 86ce72927..779a1d9c0 100644 --- a/apps/server/api/src/api/ssh/__tests__/ssh-adversarial-races.test.ts +++ b/apps/server/api/src/api/ssh/__tests__/ssh-adversarial-races.test.ts @@ -527,5 +527,59 @@ describe("SSH races + disabled account + server-side bound clamps (spec 2026-10- expect(await fifth.text()).toContain("quota_runs"); expect(scripted.cmdsOf("ssh_run_start").length).toBe(before); }); + + it("six CONCURRENT starts admit exactly the ceiling: the per-owner count and the insert are one transaction (Gate C minor 6)", async () => { + // Check-then-act on a FRESH (owner, node) pair, so only the race itself + // can overshoot: the old two-counts-then-insert let interleaved starts + // all read the same pre-insert count.

A revoked pane's open WS/attach frame reads the plane row per keystroke, stamps the RAISED generation, and the node's equal-or-higher rule ACCEPTS it - so every await between commit and close was a live "revocation prevents new dispatch" violation, for an RPC round trip. Both call sites now close on the commit's beat: in sshRevoke the close runs immediately after setControl, above the row re-read and the transition dispatch; in takeSshControl immediately after transitionPaneControl returns, above the invalidate/cancel awaits. The terminate stays last (it needs the row facts and getLive). Frames stamped BELOW the raise are still refused node-side - the pinned arm - and the climb-the-fence window is now a microtask, not a round trip.

The arm now blocks on `status = "running"` alone; the human's way out is terminate (or delete) the pane, which cascades the marker through `subshell_id`. Per the coordinator ruling the migration and FK are untouched: the fix lives in the gate. Tests: parked managed pane refuses delete; terminate then delete passes; and the refused delete leaves the marker in place so the pane's restart keeps resolving as managed (the SSH seam, never the local revive).

New runs already refuse `revision_mismatch` on a stale grant, so a routine human edit made the pane's OWN key a way to restart it into a destination its grant never authorized (the doc even said revocation, not the revision, was the fence - true for an ALIVE session's streams, wrong for a FRESH dispatch). A bearer `restart` now requires `grant.connectionRevision === conn.revision` and refuses the frozen `revision_mismatch` code. The cookie owner is unaffected (edit-then-restart is their own act), and every non-restart bearer surface keeps the ALIVE-pane rule (a stale revision still fences nothing the already-spawned session touches).

The dispatch seam is `ssh-node-client.call`, which routes a `LOCAL_NODE_ID` target to it and feeds the agent-shaped `CommandResult` back through the identical `classify` arm, so a local refusal maps to the same `SshNodeRefusal` by equality as a socket answer's. Managed `local` input fences on the plane's own `ssh_panes.control_generation` (the machine IS the plane here) and types through the in-process local launcher. The node gate now treats `local` as always-live; the admin arm is scoped to cookie actors (a bearer reaching it passed a grant the owner minted, and `gateHumanConfig` refuses every machine credential for the config asks first). Tests: resolve + discover roundtrip through the client seam (hermetic shim ssh via SUBSHELL_SSH_PATH + a fixture HOME, pinning the tilde-default expansion), id-grammar refusals, and a REAL loopback-sshd + REAL tmux managed terminal that opens (pane up, ssh foreground, takeover echoes the raised generation, a lowered replay is refused) and closes - loud-skipped only where the stack is absent, and it RAN on this host.

The comment now says that. - M4: `readTerminalLog` / `controlStateFor` have no production consumer (the server relays managed output through the ordinary pane-log reader). Kept, and named in place as the runtime's own frozen-contract statement the `ssh-terminal-log` suite pins - the overview's bar is "do not leave a SILENT second implementation", so these two now say exactly what they are. - M5: `lstatSafe(dir)` was asked twice (TOCTOU between the calls); one read, reused. - M7: the Include-glob cap's `atRoot ? [] : next` was dead (`atRoot` is false at every point the line runs); simplified to `next`. - M8: `stale_command` is emitted nowhere (the JWS signature's freshness window refuses a stale start before any handler runs).

Rationale (in the code comment): a + bearer reaching this gate has already passed `gateGrantedUse` (its + grant), and bearers always carry `isAdmin: false`, so gating on the + flag alone would make grants dead for local connections. If the intent + was "local SSH connections are admin-only even for grantees", flip the + arm - one line. +2. Retention knob asymmetry (documented in both sweep docs): the FILE + sweeps anchor on the frozen `SSH_COMPLETED_RUN_RETENTION_MS`; the env + `SSH_RUN_RETENTION_DAYS` moves only the DB rows. Chosen to keep the + protocol-frozen window honest; an operator might expect one knob. +3. Extra fix riding C1: the HostName/Port conflict-detector bug (false + `config_ambiguous`). It was not in the brief; without it every alias + with both HostName and Port is refused, so the C1 acceptance tests + could not be honest without it. +4. M4 took the brief's keep-option (frozen-contract marker) rather than + deleting `readTerminalLog`/`controlStateFor`. +5. `ssh-resolve.test.ts` is 426 lines (guideline ~400): one concern + (resolve grammar), fixture-heavy; splitting was left for a dedicated + pass rather than done here.

Wired into the - agent's hourly sweep (job 3b). Also added the server half (I3-disk): - `sweepLocalSshFiles` runs reconcile + completed-run + probe + - terminal-state sweeps against `SUBSHELL_SERVER_DATA_DIR` from the - existing boot+hourly DB pass (terminal-state gated on the running-and- - alive row read, fail closed). Tests: old uuid deleted / fresh kept / - foreign name ignored; symlink never chased; absent dir not an error. -- M4 (29c4fb77): chose the KEEP option - `readTerminalLog`/`controlStateFor` - carry the "FROZEN-CONTRACT impl pinned by ssh-terminal-log.test.ts, not a - live caller - do not delete" note. No silent second implementation. -- M5 (29c4fb77): `lstatSafe(dir)` hoisted in `ssh-run-store.ts`. -- M6 (d8f4c454): IdentityAgent comment now describes the real behavior - (any non-`none` spelling means the account's agent == `SSH_AUTH_SOCK`). -- M7 (29c4fb77): dead `atRoot ? [] : next` branch in `ssh-discover.ts` - simplified to `return next`. -- M8 (29c4fb77): `stale_command` definition carries the RESERVED note - (emitted nowhere; the staleness defense is JWS expiry; stays for the - protocol freeze). - -## Commits (git show --stat) - -``` -=== aff243b4 fix(ssh): sweep stranded probe configs; bound the built-in node's file subtree (M3, I3-disk) === - apps/node/agent/src/commands/ssh-sweep.ts | 7 +++ - apps/server/api/src/services/ssh/ssh-retention.ts | 62 ++++++++++++++++++++++ - packages/pane-runtime/src/index.ts | 1 + - .../src/ssh/__tests__/ssh-run-store.test.ts | 50 ++++++++++++++++- - packages/pane-runtime/src/ssh/ssh-retention.ts | 40 ++++++++++++++ - 5 files changed, 159 insertions(+), 1 deletion(-) - -=== 29c4fb77 fix(ssh): the no-risk review minors (M2, M4, M5, M7, M8) === - .../api/src/services/terminal-exec-records.ts | 13 +++++++++---- - packages/pane-runtime/src/ssh/ssh-discover.ts | 7 ++++--- - packages/pane-runtime/src/ssh/ssh-run-store.ts | 7 ++++++- - packages/pane-runtime/src/ssh/ssh-terminal-log.ts | 22 +++++++++++++++++++++- - packages/subshell-protocol/src/ssh-errors.ts | 12 +++++++++++- - 5 files changed, 51 insertions(+), 10 deletions(-) - -=== c5555d47 feat(ssh): run the ssh_* verbs in-process on the built-in local node (I3) === - .../src/services/ssh/__tests__/ssh-local.test.ts | 364 +++++++++++++++++++++ - apps/server/api/src/services/ssh/ssh-local.ts | 362 ++++++++++++++++++++ - .../server/api/src/services/ssh/ssh-node-client.ts | 28 +- - apps/server/api/src/services/ssh/ssh-node.ts | 42 ++- - apps/server/api/src/services/ssh/ssh-pane-hooks.ts | 34 +- - .../api/src/services/ssh/ssh-terminals.service.ts | 11 +- - 6 files changed, 821 insertions(+), 20 deletions(-) - -=== 1b57c69e fix(ssh): resolved terminal-exec rows now age out (I6) === - .../services/ssh/__tests__/ssh-retention.test.ts | 67 ++++++++++++++++++++++ - apps/server/api/src/services/ssh/ssh-retention.ts | 64 +++++++++++++++++---- - 2 files changed, 121 insertions(+), 10 deletions(-) - -=== 384eb4d4 fix(ssh): delete the dead second takeover act (I5) === - .../src/api/ssh/__tests__/ssh-runs-route.test.ts | 14 +++-- - apps/server/api/src/api/ssh/index.ts | 5 +- - apps/server/api/src/services/ssh/ssh-pane-hooks.ts | 19 ++++--- - .../api/src/services/ssh/ssh-terminals.service.ts | 66 ++++------------------ - 4 files changed, 33 insertions(+), 71 deletions(-) - -=== 231d034e fix(ssh): refuse uploads to managed SSH panes at the server (I4) === - .../api/src/api/__tests__/uploads-route.test.ts | 69 ++++++++++++++++++++++ - apps/server/api/src/api/uploads.route.ts | 19 ++++++ - packages/backend-errors/src/error-codes.ts | 6 ++ - 3 files changed, 94 insertions(+) - -=== 5cea0fbf fix(ssh): explicit origin check on the ssh-control takeover write (I2) === - .../api/subshells/__tests__/ssh-pane-gates.test.ts | 33 ++++++++++++++++++++++ - .../api/src/api/subshells/ssh-pane-ops.route.ts | 15 ++++++---- - 2 files changed, 43 insertions(+), 5 deletions(-) - -=== 1717c40e fix(ssh): bearer restart requires the grant to pin the current revision (I1) === - .../src/services/ssh/__tests__/ssh-policy.test.ts | 64 ++++++++++++++++++++++ - .../server/api/src/services/ssh/ssh-policy-impl.ts | 25 ++++++++- - 2 files changed, 86 insertions(+), 3 deletions(-) - -=== 0d4a5d2c fix(ssh): any running managed pane blocks connection deletion (C2) === - .../src/services/ssh/__tests__/ssh-policy.test.ts | 79 ++++++++++++++++++++++ - .../api/src/services/ssh/ssh-runs.repository.ts | 13 +++- - 2 files changed, 90 insertions(+), 2 deletions(-) - -=== d8f4c454 fix(ssh): accept real OpenSSH -G default spellings and tilde identity refs (C1) === - .../src/ssh/__tests__/ssh-resolve.test.ts | 229 +++++++++++++++++++-- - packages/pane-runtime/src/ssh/ssh-discover.ts | 4 +- - packages/pane-runtime/src/ssh/ssh-resolve.ts | 60 ++++-- - 3 files changed, 256 insertions(+), 37 deletions(-) -``` - -## Full-suite lines (verbatim) - -Commands: `env -u SHELLOPTS -u BASHOPTS bun test ` (serial, repo root). - -packages/pane-runtime/src: -``` - 527 pass - 0 fail - 1341 expect() calls -Ran 527 tests across 40 files.

If the intent - was "local SSH connections are admin-only even for grantees", flip the - arm - one line. -2. Retention knob asymmetry (documented in both sweep docs): the FILE - sweeps anchor on the frozen `SSH_COMPLETED_RUN_RETENTION_MS`; the env - `SSH_RUN_RETENTION_DAYS` moves only the DB rows. Chosen to keep the - protocol-frozen window honest; an operator might expect one knob. -3. Extra fix riding C1: the HostName/Port conflict-detector bug (false - `config_ambiguous`). It was not in the brief; without it every alias - with both HostName and Port is refused, so the C1 acceptance tests - could not be honest without it. -4. M4 took the brief's keep-option (frozen-contract marker) rather than - deleting `readTerminalLog`/`controlStateFor`. -5. `ssh-resolve.test.ts` is 426 lines (guideline ~400): one concern - (resolve grammar), fixture-heavy; splitting was left for a dedicated - pass rather than done here.

Passwords, MFA entry, key unlocking, - and host-trust setup occur outside Subshell on the connecting node. - -Also deferred: Windows destinations, connection sharing, persistent remote -sessions, remote agent launch, and conversation handoff. Ordinary interactive -applications remain possible, but a terminal is not a private secret-entry form. - -Codex provides the UX reference: discover SSH hosts and select a remote project. -Its documented workflow requires Codex installed and authenticated remotely; -this design keeps the agent on an existing node instead. See the -[official SSH workflow](https://learn.chatgpt.com/docs/remote-connections#connect-to-an-ssh-host). - -### Existing features to keep - -Keep the terminal plugin, presetless terminal launches, `create_subshell.harness`, -catalog entries in `list_presets`, byte-cursor log reads, raw input, lifecycle -tools, encrypted agent channels, and enrolled-node `transfer_files`. The harness -field and catalog now serve presetless terminal discovery; earlier suggestions -to remove them no longer apply. - -Rename the visible "Cross-agent comms" grouping to **Agent-created**. Keep its -provenance flag, silent creation, and cleanup responsibility. No database-column -rename is required. Correct MCP instructions that describe every pane as an -agent. The obsolete preset-name launch instruction was already fixed on main. - -## 2. Security model and required protections - -The existing [security model](docs/security.md) is the baseline. The controls -below protect Subshell APIs; they do not sandbox a process that already runs as -the connecting OS account. Such a process may independently run SSH or read that -account's files. Compromised OS accounts, malicious administrators, and a -compromised control plane remain outside the existing trust boundary. - -The destination account determines command permissions. A remote working -directory is not a filesystem restriction. Arbitrary remote shell access also -permits network access and privilege use available to that account. - -| Design risk | Required mitigation | +# SSH support: remote runtime over SSH + +Revised: 2026-10-05. +Status: corrected product direction; transport design and implementation pending. +Reviewed implementation: PR #330, head `f18f168724505f840831ad3f1f494c6112716798`. + +## 1. This supersedes the previous design + +The user clarified the intended experience: select an SSH host, start the Subshell +runtime on that host through SSH, select a remote directory, and work there. The +remote machine has Subshell installed. SSH carries the ongoing runtime connection. + +The previous document instead kept the agent on an existing node and gave it tools +for executing commands on an ordinary SSH destination. PR #330 implements that +older model. That is an architectural mismatch, not something fixed by moving the +settings page or improving its copy. + +This document replaces the previous implementation mandate. A separate SSH command +runner, destination grants per agent pane, and dedicated SSH execution tools are +superseded. Earlier security reviews do not certify the replacement architecture. +Do not merge PR #330 as satisfying this revised experience. Preserve useful work +selectively; do not blindly revert the branch or delete local test data. + +Current authorized work is updating this plan and the PR instructions only. The +implementation rework has not been requested in this session. + +## 2. Reference experience and product contract + +The [official Codex SSH documentation](https://learn.chatgpt.com/docs/remote-connections#connect-to-an-ssh-host) +describes discovering concrete aliases in `~/.ssh/config`, requiring Codex installed +and authenticated remotely, starting its app server there through SSH, and selecting +a remote project folder. It also documents managing that app server through SSH. + +This is the familiarity target. The documentation establishes a workflow, not the +reliability of our implementation or Codex's precise internal transport. Do not +claim automatic installation, identical wire protocols, or identical reconnection +semantics without evidence. + +### Primary user journey + +1. Choose **Connect over SSH** in Subshell Client or the web UI. +2. In the desktop client, use this computer's SSH setup. In the web UI, select + an eligible existing node to make the connection. Select a host from that + initiating machine's existing SSH configuration. +3. Check that the remote `subshell` runtime is installed and compatible. +4. Start the runtime through SSH and choose a remote directory. +5. Choose an installed agent harness/preset or a terminal and launch it **on that + remote machine**. +6. Work with ordinary Subshell panes and workspaces, with the remote host and + directory clearly visible. + +Saved hosts and recent directories are appropriate conveniences. A personal +Connections view may manage them. An administrative SSH configuration and grant +management workflow is not the primary experience. + +There is no required **Add node**, enrollment key, daemon service installation, or +remote callback connection to the server. Internal execution-target records may +reuse node machinery without exposing fleet enrollment as a prerequisite. In our +vocabulary, the remote program is the `subshell` node/runtime binary, not the +Subshell Client desktop application. + +### Confirmed scope and defaults + +- Support both user-confirmed origins: Subshell Client using its local OS account, + SSH configuration, and credentials; and the web UI using an existing node's + account/configuration/credentials. The browser never reads laptop SSH files. + The web flow labels the connecting machine explicitly and selects it before + listing aliases. Only actual owners can broker through enrolled nodes; the + built-in server node requires an admin and its existing launch/maintenance gates. + Node sharing or an admin boost on somebody else's node does not confer use of + that OS account's SSH credentials. Explain unavailable choices without weakening + server-side authorization. +- Require a compatible remote runtime for the initial milestone. If missing, give + installation guidance for the binary alone; never send users through enrollment + or `subshell setup`. Automatic deployment/upgrades need separate signed-artifact + handling and explicit user action, and are not assumed Codex parity. +- Agent CLIs and their authentication live on the remote host. Surface missing + requirements honestly; never run the agent locally as a fallback or copy local + agent credentials automatically. +- Linux/macOS destinations first. Retain the earlier keys-only baseline unless + explicitly revised. Do not add password/key-unlock forms inside recorded panes. +- The existing control plane remains the authority for panes/workspaces; no second + control plane is required on the destination. +- Remote directory selection and ordinary agent access to remote files are v1 + capabilities. Cross-host synchronization, conversation handoff, shared hosts, + Windows destinations, and unattended persistent services are later scope. + +## 3. Architecture requirements + +### Start a remote runtime and keep SSH as the transport + +Add a session-scoped mode to the existing `subshell` binary. A connection broker +in Subshell Client or an existing node starts it through SSH and carries a framed +runtime protocol over that connection. +Reuse node command executors, pane runtime, plugin detection data, and NodeLauncher +interfaces where sound. Remote files, tools, PTYs, and agent processes belong to +that environment. + +The runtime must start without enrollment configuration, node bearer keys, service +installation, or inbound network listeners. SSH is the ongoing runtime transport, +not an installer for the existing outbound WebSocket daemon. An internal adapter +is appropriate; silently requiring direct remote-to-server connectivity is not. + +The web path is browser → control plane → existing connecting node → SSH → remote +runtime. The existing node's authenticated link relays the session; the destination +does not enroll or create its own server connection. Desktop initiation uses the +native broker instead. Both paths share the same remote runtime and capabilities, +and both show the origin machine when it matters to connectivity or credentials. + +### Preserve desktop privilege separation + +`apps/client/desktop/AGENTS.md` documents that the server-loaded main window has +only `desktop_open_in_browser`; privileged actions live in trusted bundled/native +code. Keep that boundary. Local host discovery and SSH process creation must not +be exposed as arbitrary commands to server-loaded or redirected web pages. + +Bind the broker connection to an explicitly selected control plane, authenticated +user, SSH host, and runtime session. An alias or runtime ID is not a credential. +Do not let an unauthenticated webpage reuse local SSH access. + +### Route remote MCP and hooks through the session + +The current node daemon dials `/ws/node` with enrollment credentials, while +`packages/mcp-core` calls the control plane over HTTP. The replacement must address +both assumptions. Remote pane MCP, reporter hooks, logs, lifecycle events, and +filesystem operations need an authorized path through the runtime/broker session. +No direct network route from the remote host to the control plane is required. + +Preserve per-pane identities and normal permission checks. Do not put a full server +credential on the destination or introduce an unauthenticated/general-purpose proxy. +The precise broker/server authentication and callback protocol are Gate A work. + +### Ordinary capabilities in a remote environment + +Launch agents/terminals, browse remote directories, attach/read, interrupt, resume +where supported, and terminate through the ordinary session model. Agents use +their normal filesystem/shell tools on that host. `execute_ssh_command` is not the +required way to work in a remote project. Directory browsing is part of setup, +not an optional later file-transfer feature. + +## 4. Security and lifecycle constraints + +- SSH keys, authentication agents, and configuration stay on the initiating + computer. Preserve host-key verification; never auto-accept changed keys or send + private keys to the control plane or agent prompts. +- SSH configuration is trusted executable local configuration. Alias discovery + should not execute it; resolution is a user-initiated action. Do not carry over + the old server-side configuration snapshot ceremony merely because it exists. +- Support ordinary host/user/key and ProxyJump configuration. Enforce the session + policy against unintended agent/X11 forwarding, configured port forwards, escape + commands, local commands, and ambient control-socket reuse. Unsupported required + settings need clear errors, not silent behavior changes. +- Scope runtime authorization to user, control plane, host, and session. Authority + to establish a runtime does not authorize arbitrary local commands or access to + another user's runtime. +- Use bounded framing and queues. Runtime stdout is protocol-only and stderr is + diagnostic. Login banners, startup output, malformed frames, wrong versions, and + oversized messages must fail safely. +- Use explicit argv and correct quoting through the remote login-shell boundary. + Paths are data, not executable fragments. +- Preserve the existing OS-account trust boundary; SSH runtime mode is not an OS + sandbox. Treat all remote output as untrusted data. +- Disconnect means unavailable, not successful completion. Never replay launch, + input, or other mutating operations automatically after an uncertain result. +- Reconnect must reconcile session-owned resources, not duplicate panes or kill + unrelated processes. Establish close/orphan behavior explicitly before promising + process survival. Session runtime must coexist safely with any enrolled daemon + already on the same machine, using isolated ownership/artifact namespaces. +- Bound logs, storage, reconnect work, and subprocess resources. Keep private file + permissions and avoid credentials/command/output payloads in operational logs. +- Keep normal user/pane authorization. Removing the old destination-grant UI does + not make remote runtimes accessible to every account or shared pane. + +## 5. Disposition of PR #330 + +| Existing work | Required disposition | | --- | --- | -| Every existing agent silently gains access to SSH credentials | Explicit SSH token permission plus a human-issued per-pane, per-connection grant; no legacy permission fallback | -| Generic pane APIs bypass connection permissions | One SSH authorization policy used by all REST, WebSocket, preview, log, lifecycle, and sharing surfaces | -| Human takeover is mistaken for confidential input | State that takeover controls input, not historical secrecy; defer in-app SSH secret entry | -| SSH config starts local helpers, forwards ports, or reuses ambient connections | Human-only resolution followed by an approved normalized configuration and mandatory runtime restrictions | -| Commands are repeated after an ambiguous disconnect | Durable acceptance before spawn, request binding, reconciliation, and no automatic replay | -| A quiet pane is mistaken for an idle shell | Keep terminal exec explicitly heuristic; use supervised SSH processes for structured commands | -| Output floods memory or disk | Bound accumulation, reads, retention, concurrency, and aggregate storage; drain excess output | -| Remote output impersonates trusted UI | Render output as data and keep authoritative identity/control outside terminal text | - -### Ownership and explicit grants - -A connection is a resource, not an enrolled node. Only the node owner may -configure connections through an enrolled node. An administrator may configure a -private connection through the server's built-in node, subject to its existing -launch-enabled and maintenance rules. Admin status does not bypass those rules -or grant API access to another user's private connection. - -Human configuration, discovery, grants, and control changes require a cookie -session. Validate request origin/CSRF on these writes explicitly; do not assume -cookie authentication alone is sufficient. Machine credentials cannot call them. - -A grant binds a connection revision to a pane ID and its current credential -generation (the issued API-key identity). It records the granting human and -revocation state. It permits that pane to read/use that connection, not configure -it. Both a coarse `ssh` permission and this row-level grant are required. Old -tokens receive no grandfathering; a human can restart a pane to obtain a current -token and then grant it access. Child panes and restarted panes inherit nothing. - -MCP lists only the connections granted to the caller. Every operation rechecks -the token, pane lifecycle, owner, grant, connection revision, and node eligibility. -Inaccessible resource IDs use the existing non-enumerating 404 convention. - -### Generic pane surfaces and revocation - -Managed SSH panes remain private even though their rendering and lifecycle reuse -ordinary panes. Gate list previews, detail reads, logs, captures, live updates, -attach-token minting and redemption, input, exec, prompt injection, restart, -termination, deletion, and sharing through the connection policy. Sharing SSH -panes is refused in v1. Same-owner sibling panes need their own grants. - -Do not mint MCP credentials or inject Subshell credentials into SSH processes. -Existing machine-minted attach tokens retain their caller identity and are -rechecked against SSH grants and control state when redeemed. Active subscriptions -must also be closed or filtered when permission/control changes. - -Revocation prevents new dispatch, rejects queued input, closes affected streams, -and cancels runs/terminals initiated under that grant where reachable. Human-owned -sessions and work initiated under other valid grants are not cancelled. Bind each -resource to its initiating grant/credential so this distinction is enforceable. -Offline cancellation stays pending and is dispatched before new work on reconnect. -Terminating SSH never guarantees remote descendants died. - -### Authentication and trust - -All managed SSH invocations use noninteractive key/certificate authentication, -including interactive shell sessions. An already-unlocked authentication agent -may be used. Password, MFA, key-unlock, and unknown-host requirements produce -actionable instructions to configure the connecting account outside Subshell. -There is no host-key acceptance endpoint in v1. - -Require existing verified host trust. Unknown, changed, and revoked keys fail -closed. Keep certificate/revocation checks and secure algorithm defaults. A key -scan is not identity verification and must never become an automatic trust step. - -### Configuration is executable, not passive data - -OpenSSH supports local helper execution, forwarding, and multiplexed connections; -see the [OpenSSH configuration reference](https://man.openbsd.org/ssh_config). -Discover aliases by bounded parsing of the account's config and includes; omit -wildcard-only entries, detect include cycles, and allow manual aliases. Discovery -returns names, not config file contents. Resolution/testing is a human action and -must disclose that trusted configuration such as `Match exec` can run locally. - -Persist an approved normalized snapshot after resolution. Agent requests accept -only connection IDs, never raw hosts, usernames, ports, SSH options, environment -overrides, config paths, or proxy commands. Render runtime config from an explicit -allowlist; do not let runtime SSH reread ambient user/system configuration. - -Supported resolved settings are destination host/user/port, identity and -certificate references, authentication-agent reference, host-trust references -and host-key alias, and a bounded `ProxyJump` chain. Normalize every hop under the -same restrictions. Preserve referenced trust files and their revocation/CA -semantics. Defer arbitrary `ProxyCommand`, dynamic known-host commands, provider -commands, and other required settings that cannot be represented safely; refuse -with a named limitation rather than silently changing connection semantics. - -Mandatory runtime policy applies to every hop: strict host checking, no -agent/X11 forwarding, no configured local/remote/dynamic forwards or tunnels, no -local commands or SSH escape commands, and no ambient control sockets or -multiplexing. Do not import `RemoteCommand`, `SendEnv`, or `SetEnv`. Unsupported -client options fail setup rather than silently omitting a protection. Validate -this policy on supported Linux and macOS OpenSSH versions. - -Configuration edits create a new revision and invalidate grants. Refuse edits -while work is active; the human must stop or finish it first. Trusted local OS -changes to referenced keys/trust files remain inside the OS trust boundary. - -Spawn using explicit argv and a minimal environment: no app secrets, Subshell -credentials, preset environment, loader overrides, shell startup overrides, or -askpass hooks. Allow an authentication-agent socket only from trusted connecting -account setup. Reject option-like aliases/control characters; quote remote -directory arguments as POSIX data. Only `command` is intentional shell code. - -## 3. Product behavior and execution contracts - -### Connection UI - -Add **SSH connections** to user settings: select connecting node, choose/enter -alias, review resolved destination and connecting OS account, set optional -absolute remote directory, test, save, then grant selected panes separately. - -Always show the route, for example **Staging · deploy@app-02 · via Laptop**. -Distinguish remote paths from connecting-node paths. Remote OSC titles cannot -replace the trusted destination label. Show connecting-node unavailability -separately from destination/authentication errors. File uploads to SSH terminals -are disabled until remote file operations exist. - -### Structured commands - -Path: SPA/MCP → server authorization → signed/encrypted node command → shared SSH -runtime → destination. The server-hosted node uses the same runtime directly. - -Each command uses a supervised non-PTY SSH process and independent shell context. -Directory/environment mutations do not persist between commands. Keep stdout and -stderr separate. A failed directory change must prevent command execution. -Structured commands do not scrape interactive shell prompts or completion markers. - -Start returns a run ID promptly. Read returns bounded incremental output and -status; browser closure or read timeout does not cancel execution. Connection -testing uses a fixed benign probe, not caller-supplied command text. - -Use lifecycle states `accepted`, `running`, `completed`, and `unknown`, plus -separate cancellation/deadline facts. `completed` carries an observed remote exit -status; unknown must not masquerade as failed or successful. Retain local SSH -exit/signal information separately. OpenSSH's 255 status is ambiguous between -transport error and remote status; do not claim a confirmed remote result from -that number alone. See [SSH exit status](https://man.openbsd.org/ssh#EXIT_STATUS). - -Cancellation stops locally supervised SSH/helper processes with a bounded grace -period. Report remote termination as unconfirmed. Commands can daemonize or -otherwise survive the connection; no UI label should imply otherwise. - -### Durable dispatch and storage - -Allocate run IDs server-side and bind them to owner, initiating grant/credential, -connection revision, and a digest of the complete request. The connecting runtime -durably records acceptance before spawning. Duplicate delivery returns existing -state; a different payload under the same ID is refused. A crash between acceptance -and spawn produces unknown state, not automatic permission to try again. - -Reconcile known IDs after reconnect. Unknown or expired IDs are not reusable start -requests. Persist deduplication records for the full accepted-request lifetime; -deleting output must not delete replay protection. Validate signed command expiry -and reject stale starts after reconnect. Do not queue new execution while offline. - -Use opaque IDs for filesystem names, 0700 directories, and 0600 files. Refuse -symlinks/path escapes during creation, reads, and cleanup. Store output on the -connecting runtime and relay it through authorized reads; the server stores run -metadata, not a second unbounded output copy. - -| Limit | Default | -| --- | --- | -| Execution deadline | 5 minutes, caller-selectable up to 1 hour | -| Active structured runs | 4 per owner per connecting node; 16 total per connecting node | -| SSH terminals | 4 per owner per connecting node | -| Retained output per structured run | 10 MiB combined stdout/stderr | -| Aggregate SSH output storage | 1 GiB per connecting node, including managed SSH terminal logs | -| Completed-run retention | 7 days | -| Output response window | At most 256 KiB | -| Read long poll | At most 30 seconds | -| Connection/setup probe | 30-second overall deadline, no automatic execution retry | - -Bound partial lines, pending buffers, and in-flight responses. Keep draining after -capture limits and report truncation. Under disk pressure evict completed output -first; if still full, reject new work. Active SSH terminal logs need bounded -rotation with an explicit cursor-expired/reset result, never silent cursor reuse. -Use log generation plus byte offset where rotation occurs. Do not silently change -the existing non-SSH byte-cursor contract. - -Command text and output can contain secrets: keep them out of operational logs, -audit metadata, and notifications. Audit actor/resource IDs, connection revisions, -grant/control changes, destinations, and lifecycle outcomes. Render output as -text/xterm data, never HTML. No automatic link opening or clipboard access; retain -explicit human clipboard interaction. - -### Interactive terminals and input control - -Reuse rendering, geometry, short-lived attach tokens, and pane lifecycle. SSH is -the foreground process; its exit ends the pane with no connecting-node shell -fallback. Restart creates a new SSH session and rechecks authorization. Neither -local tmux nor an SSH reconnect guarantees remote-session persistence. - -Human-opened terminals start in human control; agent-opened ones start in agent -control. Humans can take over immediately. Only humans return control to agents. -Human mode blocks agent reads and writes on every API/stream, but recorded output -can become visible after return to agent control. Explain that ordinary terminal -history is not confidential secret storage. - -### Existing `exec_in_terminal` - -Keep its combined-output, POSIX-marker contract as a terminal convenience. Add -execution IDs, persistent outstanding state, and a read-only status operation. -Enforce input ownership across every write path, including restart prompts and -nudges. A caller's wait timeout leaves the reservation active; continue bounded -marker observation. A late marker can complete it; lost observation/restart makes -it unknown. An explicit human takeover invalidates the result and fences stale -queued input using the node-enforced input generation. - -Quiet output is only a heuristic; it cannot detect a silent program waiting on -stdin. Document unsupported interactive commands/shell syntax clearly and never -upgrade marker text into a security decision. Do not use this helper on managed -SSH terminals. Keep its report-only timeout behavior: no automatic Ctrl-C. -After observation becomes unknown, refuse further automated exec until human -recovery or pane restart; do not monitor or reserve unbounded memory indefinitely. - -## 4. Shared interfaces and compatibility - -These contracts must be landed by workstream A before parallel implementation. -Agents may not invent incompatible alternate shapes in their own modules. - -### Persistence - -- Connections: owner, connecting node, display name, normalized config snapshot, - remote-directory default, revision, and timestamps; no credential contents. -- Grants: connection revision, pane ID, API-key identity, human grantor, timestamps, - and revocation; unique active binding for that tuple. -- SSH runs: run ID, connection snapshot/revision, owner, initiating grant/credential, - request digest, lifecycle/cancellation facts, observation and exit information. -- Pane association: SSH connection revision, initiator, control owner/generation, - and log generation; no implicit grants via ordinary pane ownership. -- Terminal exec records: execution ID, pane incarnation, initiator, input generation, - observation state, and bounded-result metadata. - -Register migrations in both the migration directory and static boot provider. -Connection deletion is refused while work is active. Retained run history keeps -an immutable destination snapshot after the connection is deleted. - -### REST and MCP surface - -REST uses camelCase bodies and the existing authenticated service pattern. Define -schemas once server-side and validate all node wire responses with shared parsers. - -| REST family | Capability | Caller | +| Admin SSH destination page and grants workflow | Replace with personal host selection, remote folder choice, and normal launch | +| Per-pane destination grants/coarse SSH-command token permission | Retire with the old product; establish runtime/session ownership instead | +| Dedicated execute/read/cancel SSH-command and open-SSH-terminal API/MCP families | Remove/replace as transport integration lands; ordinary remote panes are the primary interface | +| One-shot SSH command supervisor and independent run database | Not the replacement runtime; salvage bounded subprocess/diagnostic primitives selectively | +| SSH discovery, diagnostics, safe argv, isolated sshd fixtures | Reuse where compatible with the initiating-client architecture | +| Snapshot, grants, run tables and old routes | Inventory and retire explicitly; no dead security gates or stray reachable APIs | +| Terminal input fencing, timeout/unknown-result handling, bounded scanning | Independently useful; keep with tests or split into a focused PR | +| Presetless terminals, cursor reads, node archive transfer already on main | Keep; do not revert baseline capabilities | +| Agent-created labeling | Keep where it describes helper-pane provenance accurately | +| Old SSH docs, tests, changesets and PR description | Rewrite around the actual replacement; old passing tests do not prove alignment | + +Although unreleased, branch migrations may already exist in development/test +instances.

Its sidebar relocation and grants-dialog polish are no longer +a sufficient correction; the architecture is superseded. + +## 6. Multi-agent delivery with a design gate + +This is a corrected product contract, not a claim that the transport design is +already decision-complete. Complete Gate A before parallel implementation. + +### Gate A: freeze and prove integration + +The coordinator must document and validate: + +1.

This document freezes the contracts §6 requires before parallel +implementation. Supersedes the destination-execution model shipped on this branch +(PR #330's product shape); the salvage list is §5 of the plan. + +## 1. Shape + +``` +browser -> control plane -> connecting node (enrolled, owner's machine) + -> ssh child (policy-rendered) -> `subshell runtime-serve` on the destination +``` + +The runtime is a session-scoped mode of the existing `subshell` node binary. It +behaves like a node whose link is the SSH child's stdio: it drives tmux on the +destination, owns pane logs, and answers the same command/event semantics. No +enrollment config, no node key, no service, no network listener on the destination. +The SSH child dies, the session ends; the tmux server and its panes survive on the +destination (tmux outlives its clients) and the next session reconciles them. + +**Both origins are covered by one broker.** The web path selects an eligible +connecting node. Subshell Client's own machine is exactly such a node, so the +laptop experience is the same flow with the client's node chosen; nothing new is +exposed to any server-loaded webview (desktop privilege separation untouched). The +Server assistant gains no SSH commands. + +## 2. Framing and negotiation + +Transport: the SSH child's stdin/stdout, 4-byte big-endian length prefix + one JSON +frame, `MAX_SESSION_FRAME_BYTES` = 262144, inbound queue bounded (128 frames; +overflow closes the session fail-closed). stdout is protocol-only; stderr is +diagnostic text forwarded to logs without interpretation. Login banners and +malformed leading bytes fail the open, never a silent skip. + +Hello (first runtime frame): `{ type: "hello", runtimeProtocol: 1, agentVersion, +os, arch, capabilities, homeDir, dataDir, tmuxSocket, paneCount }`. +Plane refuses a major mismatch by name. `runtimeProtocol` is its own version +namespace; the node link family is unchanged in content, but the new commands and +events bump `NODE_PROTOCOL_VERSION` to 17 with `MIN_NODE_VERSION` raised in step +(exact-match gate, both sides released together). + +Plane-to-runtime command frames mirror the node command bodies the runtime needs, +minus crypto: `launch` (terminal or presetless harness argv under the runtime's +tmux), `input`, `terminate`, `kill`, `capture`, `log_read`, `tail_start/stop`, +`list_dirs`, `subshells_report`, `close`. Runtime-to-plane event frames mirror +`NodeEvent`: `result{ref}`, `output`, `exit`, `subshells_report`, `rest_response`. +The runtime reuses `TmuxRunner`, `pane-log` self-invoke, exit watcher, and the +executors in `apps/node/agent/src/commands/` under a shared runtime core extracted +from the agent; the daemon keeps its own dispatch over the WS link. + +## 3. Broker (connecting node) + +New node command family `ssh_session_open/send/close` (protocol 17): + +- `ssh_session_open { ref, target: { alias, host, port, user, identityFile? } }`: + the agent first probes the runtime (`sh -lc "command -v subshell"`, short RPC over + the same policy render); absent answers `SSH_RUNTIME_MISSING` with install + guidance for the binary only. Present: spawn via the salvaged + `buildSshInvocation` + `renderSshConfigContents` (mandatory deny-by-default + policy, `HostKeyAlias`, ProxyJump, BatchMode, keys-only) with the remote command + `subshell runtime-serve --session ` composed through the existing + `remoteCommandLine` quoting. The child leads its process group + (salvaged `killGroup`). Bounded pump: child stdout frames sealed into new + `NodeEvent` arm `session_frame { ref, data_b64 }` (size-capped, backpressured by + `bufferedAmount` like the tail pump); plane sends `ssh_session_send { ref, + data_b64 }` for runtime stdin. The supervisor lives beside `SshRunSupervisor` + with the same durable-accept, deadline, and boot-reconcile posture; at agent + exit the child goes with it. +- Open result carries the parsed hello plus the real `host:port` and account. + Identity files, config contents, and key material never enter any frame or row. + +Frame routing is by `ref` (plane-minted uuid). A frame naming another node's or +another session's ref is dropped; the node keys children by ref, one SSH child per +session. + +## 4. Plane: sessions as execution targets + +New tables (migration 0049): `ssh_runtime_sessions` (id, owner_id, +connecting_node_id, alias, host, port, user, status `opening|active|lost|closed`, +hello facts JSON, created/last_seen/closed) and hidden `nodes` rows with +`kind = 'runtime'` (owner-only, no node key, never listed by `GET /api/nodes`, +never dialable, never enrolled). Panes keep the ordinary `subshells` row with +`nodeId` set to the runtime node, so list/detail/log/live/ws all stay normal. + +`launcher-registry.ts` gains a branch: a `runtime`-kind node resolves to a new +`RuntimeSessionLauncher` implementing the existing `NodeLauncher` interface; it +serializes launch/input/tail through §3's frames instead of signed WS commands. +`RemoteLauncher` stays untouched. + +Authorization: opening a session requires the caller to **own** the connecting +node (salvaged `sshNodeGate`: real owner, no admin boost, no share; `local` keeps +its admin gate in-process). The session row carries `owner_id`; every pane created +through it belongs to that user; cross-account frames are impossible because refs +resolve only within the caller's sessions. Sharing follows ordinary pane sharing, +nothing session-level. + +## 5. MCP and reporter callbacks through the session + +The runtime serves its panes' callbacks on a private unix socket +`/callback.sock` (0600, mode-pinned, no network bind): the one +listener class permitted by "no inbound network listener", inside the destination +OS-account boundary. + +- `subshell mcp` on the destination detects `SUBSHELL_RUNTIME_CALLBACK_SOCK` and + routes its single `ToolApi.req` seam over the socket to the runtime as + `rest_request { reqId, method, path, body }` frames. The runtime forwards them + bounded; the plane executes the path **as the pane's own subshell token**, which + the plane minted at launch and never transmits. Only paths the pane could call + with its own token pass (`/api/subshells//*`, extend, identities, + channels): a fixed allowlist of prefixes with the pane's id substituted, not a + general proxy. Responses ride `rest_response` back. +- Exit and reporter hooks (`subshell report`, exit-hook) ride the same pipe; they + already speak the same token. +- The token itself never leaves the plane; the destination never learns the plane + URL as a network requirement. Blocking destination-to-plane connectivity is a + supported configuration and must be tested. + +## 6. Lifecycle + +- **Disconnect**: SSH child dies (network, user, reboot) -> broker reports close, + plane marks the session `lost` and its runtime node offline. Panes read + `alive:0` with status intact: unavailable, not completed. No launch, input, or + mutating frame is ever replayed; uncertain results surface as `unknown` + (salvaged exit-255 honesty posture). +- **Reconnect**: user reopens the same destination (recent aliases are rows + history); runtime reconciles by listing the destination tmux socket named + deterministically per destination (`subshell-ssh-`), so a + second session on the same machine finds the first session's panes; plane matches + reported pane ids to existing rows (idempotent restore, duplicates impossible + because pane ids come from the rows). +- **Close**: `subshell runtime-serve` exits after forwarding its final report; + tmux server and panes keep running under the destination user. Killing panes is + an explicit terminate, never an implicit close side effect. +- Coexistence: the runtime's tmux socket namespace, dataDir subdirectory + (`/runtime/`), and log dir are isolated from any separately + enrolled daemon's artifacts on the same machine. + +## 7. Selection UX and the missing runtime + +One personal flow, not an admin surface: **Connect over SSH** -> pick the +connecting node (labeled with its machine name and OS account) -> pick an alias +(salvaged `discoverSshAliases` on that node) -> Resolve shows the concrete +`host:port user` and Test proves reachability + runtime presence -> pick a remote +directory via `list_dirs` browsing on the live session -> launch (preset or +terminal) exactly as on any node. Saved destinations are personal conveniences. +Errors name the remedy: `SSH_RUNTIME_MISSING` prints the binary install pointer +(never `subshell setup`/enrollment), a version mismatch names the compatible +range, a host-key refusal says who must fix it. Old admin SSH page, grants +ceremony, run API, and the ssh MCP family retire in the same change that lands +the replacement (inventory in §5 of the plan; migrations 0047/0048 dropped by +0050 after inspecting dev instances; this instance base is single-user, so no +data-preservation burden, but the drop ships, it is not a silent revert). + +## 8. Security invariants carried over + +Keys, agents, and config stay on the connecting node; host-key verification is +mandatory (policy render unchanged); frames bounded and fail-closed; explicit +argv with per-token quoting through the login-shell boundary; remote output is +untrusted data; no server credential on the destination; per-pane token identity +for MCP preserved; authority to open a session grants nothing beyond the caller's +own panes. + +## 9. Gate A proof (vertical slice, in-repo, fixture sshd) + +Extend `e2e/fixtures/sshd.ts` destination: no enrollment config, plane unreachable +from the destination's network namespace expectation. Scenario: open session +through the connecting node -> list dirs -> launch a terminal pane -> attach and +type (output bytes land in the runtime pane log on the destination) -> MCP round +trip: from inside the pane, one call through `callback.sock` (a `curl --unix-socket` +in a terminal, or the runtime-side test harness) resolving as the pane's own token +-> terminate. Protocol 17 handshake assertion on the fixture link. This slice is +the acceptance gate for workstreams R/B/C; it does not require the UX. + +## 10. Workstream contracts + +- **R (remote runtime)**: `runtime-serve` verb on the node CLI extracting the + shared runtime core (tmux, executors, logs, exit watcher) from `apps/node/agent`; + framed stdio + hello + callback socket. Owns: `apps/node/agent/src/runtime/`. +- **B (broker)**: `ssh_session_*` commands, session supervisor, protocol 17. + Owns: `packages/subshell-protocol/src/ssh-session-frames.ts`, + `apps/node/agent/src/commands/ssh-session.ts`. +- **C (control plane)**: session tables/registry, `RuntimeSessionLauncher`, + callback execution allowlist, retirement of old doors (routes, MCP tools, + tables, policy scopes, docs). Owns: `apps/server/api/src/services/ssh-runtime/`, + migrations 0049/0050, `packages/mcp-core` ssh removal. +- **U (UX/docs)**: Connect-over-SSH flow in the SPA on frozen APIs, docs rewrite. + Only the coordinator edits shared registries (`routes.ts`, `commands/index.ts`, + `node-frames.ts` unions, `migrate.ts`) by applying worker-supplied hunks. From 9d4b56536e530f1386eca3efd111be34554cbbce Mon Sep 17 00:00:00 2001 From: Theo Gravity Date: Mon, 5 Oct 2026 16:42:12 -0700 Subject: [PATCH 077/142] feat(ssh): Gate A runtime sessions - start the Subshell runtime on the SSH destination over a brokered stdio session (design 2026-10-05) Protocol 17: ssh_session_open/send/close commands, the session_frame pump event, the 4-byte length-prefixed session codec, and the runtime hello (runtimeProtocol 1). Node side: SshSessionSupervisor (probe -> spawn -> hello gate -> durable acceptance -> boot reconcile) and the runtime-serve verb (stdio discipline, callback.sock, the node executors reused verbatim). Plane side: SshRuntimeSession byte channel, the live registry, the hidden kind=runtime node rows the pane plumbing launches onto (ordinary subshells rows, RuntimeSessionLauncher as RemoteLauncher's sibling), the callback allowlist + own-token executor, sessions rows + migration 0049, and the cookie-admin /api/ssh-runtime/sessions slice. e2e spec 22 proves the whole chain against a fixture sshd with no fakes: hello facts, launch/attach/input, the typed marker returning through framed log reads, the curl callback executing as the pane's own token (own row in, foreign path refused), no TCP listener on the destination, runtime_missing by name, close-then-reconcile paneCount, and link loss marking the session lost while the pane stays running/unavailable. Fixes found on the way: Bun.stdin.stream() (the namespace object has no getReader on 1.4.2), and issueSubshellToken stamping api_key_id onto a row that must already exist (token minted before the insert authenticated as nothing). --- apps/node/agent/package.json | 2 +- apps/node/agent/src/cli.ts | 43 ++ apps/node/agent/src/commands/index.ts | 13 + apps/node/agent/src/commands/ssh-session.ts | 117 +++ apps/node/agent/src/commands/tail.ts | 4 +- apps/node/agent/src/runtime/callback-sock.ts | 138 ++++ apps/node/agent/src/runtime/dispatch.ts | 154 ++++ apps/node/agent/src/runtime/serve.ts | 322 +++++++++ apps/node/agent/src/runtime/stdio.ts | 107 +++ apps/server/api/src/api/nodes/node-view.ts | 15 +- apps/server/api/src/api/routes.ts | 7 +- apps/server/api/src/api/ssh-runtime/index.ts | 11 + .../api/src/api/ssh-runtime/sessions.route.ts | 239 ++++++ apps/server/api/src/api/ssh/ssh-schemas.ts | 5 + apps/server/api/src/db/migrate.ts | 5 + .../migrations/0049-ssh-runtime-sessions.ts | 85 +++ .../src/db/repositories/nodes.repository.ts | 21 +- apps/server/api/src/db/types/index.ts | 2 + .../server/api/src/db/types/nodes.db-types.ts | 17 +- .../db/types/ssh-runtime-sessions.db-types.ts | 52 ++ .../api/src/services/backups/database.ts | 2 +- .../src/services/nodes/launcher-registry.ts | 24 + .../api/src/services/nodes/node-ws-handler.ts | 35 + .../__tests__/callback-allowlist.test.ts | 48 ++ .../ssh-runtime/__tests__/session.test.ts | 168 +++++ .../ssh-runtime/callback-allowlist.ts | 52 ++ .../services/ssh-runtime/callback-executor.ts | 69 ++ .../ssh-runtime/runtime-session-launcher.ts | 352 +++++++++ .../services/ssh-runtime/session-registry.ts | 145 ++++ .../api/src/services/ssh-runtime/session.ts | 376 ++++++++++ .../ssh-runtime/sessions.repository.ts | 123 ++++ .../services/ssh-runtime/sessions.service.ts | 513 +++++++++++++ bun.lock | 2 +- e2e/tests/22-ssh-runtime.spec.ts | 416 +++++++++++ packages/pane-runtime/src/index.ts | 13 + .../pane-runtime/src/ssh/ssh-run-child.ts | 7 +- .../src/ssh/ssh-session-supervisor.ts | 682 ++++++++++++++++++ .../src/__tests__/node-frames.test.ts | 6 +- .../src/__tests__/ssh-frames.test.ts | 8 +- .../src/__tests__/ssh-session-frames.test.ts | 308 ++++++++ packages/subshell-protocol/src/index.ts | 34 + packages/subshell-protocol/src/node-frames.ts | 50 +- .../subshell-protocol/src/node-results.ts | 14 + packages/subshell-protocol/src/ssh-errors.ts | 17 + packages/subshell-protocol/src/ssh-limits.ts | 22 + .../src/ssh-session-codec.ts | 136 ++++ .../src/ssh-session-frames.ts | 598 +++++++++++++++ packages/subshell-protocol/src/versions.ts | 11 +- 48 files changed, 5570 insertions(+), 20 deletions(-) create mode 100644 apps/node/agent/src/commands/ssh-session.ts create mode 100644 apps/node/agent/src/runtime/callback-sock.ts create mode 100644 apps/node/agent/src/runtime/dispatch.ts create mode 100644 apps/node/agent/src/runtime/serve.ts create mode 100644 apps/node/agent/src/runtime/stdio.ts create mode 100644 apps/server/api/src/api/ssh-runtime/index.ts create mode 100644 apps/server/api/src/api/ssh-runtime/sessions.route.ts create mode 100644 apps/server/api/src/db/migrations/0049-ssh-runtime-sessions.ts create mode 100644 apps/server/api/src/db/types/ssh-runtime-sessions.db-types.ts create mode 100644 apps/server/api/src/services/ssh-runtime/__tests__/callback-allowlist.test.ts create mode 100644 apps/server/api/src/services/ssh-runtime/__tests__/session.test.ts create mode 100644 apps/server/api/src/services/ssh-runtime/callback-allowlist.ts create mode 100644 apps/server/api/src/services/ssh-runtime/callback-executor.ts create mode 100644 apps/server/api/src/services/ssh-runtime/runtime-session-launcher.ts create mode 100644 apps/server/api/src/services/ssh-runtime/session-registry.ts create mode 100644 apps/server/api/src/services/ssh-runtime/session.ts create mode 100644 apps/server/api/src/services/ssh-runtime/sessions.repository.ts create mode 100644 apps/server/api/src/services/ssh-runtime/sessions.service.ts create mode 100644 e2e/tests/22-ssh-runtime.spec.ts create mode 100644 packages/pane-runtime/src/ssh/ssh-session-supervisor.ts create mode 100644 packages/subshell-protocol/src/__tests__/ssh-session-frames.test.ts create mode 100644 packages/subshell-protocol/src/ssh-session-codec.ts create mode 100644 packages/subshell-protocol/src/ssh-session-frames.ts diff --git a/apps/node/agent/package.json b/apps/node/agent/package.json index d2b6b8e53..d90f40703 100644 --- a/apps/node/agent/package.json +++ b/apps/node/agent/package.json @@ -1,7 +1,7 @@ { "name": "@internal/node", "description": "subshell — node daemon: enrolls with the control plane and executes signed commands", -

From c41625777a45db008f2247d0abf6b9b90782f7b5 Mon Sep 17 00:00:00 2001 From: Theo Gravity Date: Mon, 5 Oct 2026 17:07:24 -0700 Subject: [PATCH 078/142] refactor(ssh): split the session wire family and the broker by concern (review M3), add the census grammar ssh-session-frames.ts (598) splits into wire types + constants and ssh-session-frame-parsers.ts (the ssh-frames/ssh-run-facts precedent): every validator moves as a pure relocation, and the hello version doc now says what the parser speaks (one integer, matched by equality - no minor the grammar cannot represent; review NIT 1). New parseSshRuntimeReportRows is the census grammar shared by the subshells_report event arm and the close command's result payload (the shape C1 needs delivered). ssh-session-supervisor.ts (682) splits into the child lifecycle (class, open/send/close, pumps, exit group-kill), ssh-session-store.ts (the record store: durable acceptance, boot reconcile scan, 0600 discipline), and ssh-session-invocation.ts (per-destination facts: deterministic socket name, target snapshot, hello-boundary scan). No behavior change: the supervisor delegates to the same code through new seams. Both barrels keep every external name reachable; importers updated to point at the source that now holds each symbol. --- packages/pane-runtime/src/index.ts | 4 +- .../src/ssh/ssh-session-invocation.ts | 133 ++++++ .../pane-runtime/src/ssh/ssh-session-store.ts | 145 ++++++ .../src/ssh/ssh-session-supervisor.ts | 249 ++--------- .../src/__tests__/ssh-session-frames.test.ts | 23 + packages/subshell-protocol/src/index.ts | 6 +- packages/subshell-protocol/src/node-frames.ts | 11 +- .../subshell-protocol/src/node-results.ts | 3 +- .../src/ssh-session-frame-parsers.ts | 378 ++++++++++++++++ .../src/ssh-session-frames.ts | 411 ++---------------- 10 files changed, 773 insertions(+), 590 deletions(-) create mode 100644 packages/pane-runtime/src/ssh/ssh-session-invocation.ts create mode 100644 packages/pane-runtime/src/ssh/ssh-session-store.ts create mode 100644 packages/subshell-protocol/src/ssh-session-frame-parsers.ts diff --git a/packages/pane-runtime/src/index.ts b/packages/pane-runtime/src/index.ts index da4e0357b..1f39f0478 100644 --- a/packages/pane-runtime/src/index.ts +++ b/packages/pane-runtime/src/index.ts @@ -181,6 +181,8 @@ export { SshRunSupervisor, type SshSupervisedRunRequest, } from "./ssh/ssh-run-supervisor.js"; +export { sessionTargetSnapshot, sshSessionTmuxSocket } from "./ssh/ssh-session-invocation.js"; +export { type SshSessionLifecycle, type SshSessionRecord, SshSessionRecordStore } from "./ssh/ssh-session-store.js"; export { getSshSessionSupervisor, peekSshSessionSupervisor, @@ -190,8 +192,6 @@ export { type SshSessionOpenRequest, SshSessionSupervisor, type SshSessionSupervisorDeps, - sessionTargetSnapshot, - sshSessionTmuxSocket, } from "./ssh/ssh-session-supervisor.js"; export { runSshProcess, type SshProcessResult, sshChildPath } from "./ssh/ssh-spawn.js"; export { diff --git a/packages/pane-runtime/src/ssh/ssh-session-invocation.ts b/packages/pane-runtime/src/ssh/ssh-session-invocation.ts new file mode 100644 index 000000000..a7c431aa2 --- /dev/null +++ b/packages/pane-runtime/src/ssh/ssh-session-invocation.ts @@ -0,0 +1,133 @@ +import { createHash } from "node:crypto"; +import { userInfo } from "node:os"; +import { join } from "node:path"; +import { + parseSshRuntimeHello, + type SshConnectionSnapshotWire, + type SshSessionTargetWire, +} from "@internal/subshell-protocol"; + +/** + * The broker's per-destination facts (design 2026-10-05 §3/§6): the pieces + * the supervisor composes BEFORE and AROUND a spawn that are not about the + * child's lifecycle - the deterministic tmux socket name that makes a second + * session to the same machine land on the same server, the approved snapshot + * a session target renders to, and the hello-boundary scan that is the + * broker's ONLY frame awareness.

The settle half moved to session-settle.ts (review M3 for sessions.service.ts, 513 lines), where forgetRuntimeLauncher evicts the per-session launcher cache entry (M5: the pane-token plaintext map rode that entry forever). I1: reconcileSshRuntimeSessionsAtBoot wired into bootServer beside the pane reconcile; boot-reconcile.test.ts EXECUTES the sweep (opening/active -> lost + closedAt, runtime rows -> offline, terminal rows untouched, a second sweep is a no-op) and pins the composition (index.ts calls it). I2 + the C1 proofs: e2e spec 22 grows close (pgrep: BOTH halves of the channel - ssh child and destination runtime - are gone after close; the pane's tmux session survives; the row reads alive:false, review NIT 2), a REST terminate that kills the destination pane through the frame while the session stays active, and the child-died-with-link-alive arm (SIGTERM the ssh child by its config-path argv, the lost event lands while the node row stays online). 10/10 green. M1: migration 0049 connecting_node_id is SET NULL, matching its own doc and the ssh_runs precedent (0048): history outlives the machine. The dev-only note: checkouts that already ran 0049 keep the old FK until the table is rebuilt (nothing shipped; single-user). M2: callback truncation no longer slices UTF-16 chars against a byte budget or appends unparsable text: an oversize body is cut at a UTF-8 code point boundary and wrapped in {"subshell_truncated": true, body}, with the frame budget measured after encoding against the worst-case envelope (binary search over prefix lengths; the probe mirrors the codec instead of calling the throwing encoder). Multibyte + surrogate + escape-blowup tests. M4 (the token seal): resolveLaunchNode and the restart gate refuse a runtime-kind node BY NAME before anything composes - create, restart, and the auto-pick matrix all pinned. Without this the invariant held only on the accident of resolveBinary answering null. NITs: the pgrep pattern's honesty comment (both halves carry the ref), the containment test names the union, the runtimeProtocol doc/parser agree. --- .../api/src/api/ssh-runtime/sessions.route.ts | 4 +- .../subshells-runtime-seal.route.test.ts | 109 +++++++++ .../migrations/0049-ssh-runtime-sessions.ts | 24 +- .../db/types/ssh-runtime-sessions.db-types.ts | 20 +- apps/server/api/src/index.ts | 12 + .../subshells-resolve-launch-node.test.ts | 57 +++++ .../src/services/nodes/launcher-registry.ts | 32 ++- .../__tests__/boot-reconcile.test.ts | 158 +++++++++++++ .../__tests__/callback-executor.test.ts | Bin 0 -> 4000 bytes .../ssh-runtime/__tests__/session.test.ts | 175 ++++++++++++++- .../__tests__/sessions-close.test.ts | 210 ++++++++++++++++++ .../services/ssh-runtime/callback-executor.ts | 86 ++++++- .../services/ssh-runtime/session-settle.ts | 142 ++++++++++++ .../api/src/services/ssh-runtime/session.ts | 35 ++- .../services/ssh-runtime/sessions.service.ts | 119 +++------- .../api/src/services/subshells.service.ts | 32 ++- e2e/tests/22-ssh-runtime.spec.ts | 184 +++++++++++++-- 17 files changed, 1264 insertions(+), 135 deletions(-) create mode 100644 apps/server/api/src/api/subshells/__tests__/subshells-runtime-seal.route.test.ts create mode 100644 apps/server/api/src/services/ssh-runtime/__tests__/boot-reconcile.test.ts create mode 100644 apps/server/api/src/services/ssh-runtime/__tests__/callback-executor.test.ts create mode 100644 apps/server/api/src/services/ssh-runtime/__tests__/sessions-close.test.ts create mode 100644 apps/server/api/src/services/ssh-runtime/session-settle.ts diff --git a/apps/server/api/src/api/ssh-runtime/sessions.route.ts b/apps/server/api/src/api/ssh-runtime/sessions.route.ts index de3e47c7d..86b7dd4d5 100644 --- a/apps/server/api/src/api/ssh-runtime/sessions.route.ts +++ b/apps/server/api/src/api/ssh-runtime/sessions.route.ts @@ -73,7 +73,9 @@ const HelloSchema = t.Object({ const SessionViewSchema = t.Object({ id: t.String({ description: "Session id (the plane-minted broker ref)" }), - connectingNodeId: t.String({ description: "The node that brokered the SSH child" }), + connectingNodeId: t.Nullable( + t.String({ description: "The node that brokered the SSH child; null once that machine row has been deleted" }), + ), runtimeNodeId: t.String({ description: "The hidden runtime node row the session's panes carry" }), alias: t.String({ description: "The config token chosen at review time" }), host: t.String({ description: "Reviewed destination host" }), diff --git a/apps/server/api/src/api/subshells/__tests__/subshells-runtime-seal.route.test.ts b/apps/server/api/src/api/subshells/__tests__/subshells-runtime-seal.route.test.ts new file mode 100644 index 000000000..7c9104d32 --- /dev/null +++ b/apps/server/api/src/api/subshells/__tests__/subshells-runtime-seal.route.test.ts @@ -0,0 +1,109 @@ +import { afterAll, beforeAll, describe, expect, it } from "bun:test"; +import { hashPassword } from "better-auth/crypto"; +import { Elysia } from "elysia"; +import { subshellRoutes } from "@/api/subshells/index.js"; +import { db } from "@/db/index.js"; +import { NodesRepository } from "@/db/repositories/nodes.repository.js"; +import { SubshellsRepository } from "@/db/repositories/subshells.repository.js"; +import { UsersRepository } from "@/db/repositories/users.repository.js"; +import { NODE_KIND_RUNTIME } from "@/db/types/nodes.db-types.js"; +import { errorHandlerPlugin } from "@/plugins/error-handler.plugin.js"; +import { deleteUserByEmailOrId, setupAuthTables, signIn } from "../../__tests__/helpers/auth-tables.js"; + +/** + * The runtime seal at the HTTP surface (design 2026-10-05 §4, review M4): + * ordinary create and restart must refuse a `runtime`-kind node BY NAME. + * + * The invariant this pins is the load-bearing one the whole callback design + * rests on: "the token never leaves the plane".

Launch ships TERMINAL only, shaped for the sibling preset list.

The node's operating-system account holds the SSH keys, certificates, and host trust; Subshell stores only a normalized description of the destination and where to find the credential files. Connections appear in your account under **SSH connections** in settings, and they are private: an admin can configure connections on the server's built-in node, but nobody reaches another account's connections. - -The route always names three things: the connection label, the destination account and host, and the connecting node. A connection saved as **Staging** for `deploy@app-02` through your **Laptop** node reads `Staging · deploy@app-02 · via Laptop` everywhere it appears. Remote paths are always marked as paths on the destination, never as paths on the connecting node. - -## Set up a connection - -1. In the server dashboard's sidebar, open **Settings** → **SSH connections** and choose **New connection**. -2. Pick the connecting node. The node must be online and owned by you (or be the server's built-in node, which needs admin rights). -3. Choose an alias from the node's SSH configuration, or enter one manually.

Resolution is a human action, and it discloses that trusted local SSH configuration can run helper programs on the node when it resolves. -5. Set an optional absolute remote directory. Commands run there unless they say otherwise. -6. Test the connection, then save it. Testing runs a fixed benign probe, never a command you typed. +``` +browser → control plane → one of your enrolled machines (runs ssh) + → SSH session → `subshell runtime-serve` on the destination → ordinary panes +``` -Saved settings cover the destination host, user, and port; identity and certificate references; an already-unlocked authentication-agent reference; host-trust references and the host-key alias; and a bounded jump-host chain. Anything that cannot be represented safely, such as a `ProxyCommand` or port forwarding, is refused with a named limitation rather than silently dropped. Later edits create a new revision and invalidate existing grants, and an edit is refused while runs or terminals are still open on the connection. +The runtime is a session-scoped mode of the same `subshell` binary your node runs. On the destination it drives tmux, owns the pane logs, and answers commands over the SSH link itself. There is no enrollment, no node key, no service, and no network port opened on the destination: the SSH link is the whole connection, and the session ends with it. -Passwords, MFA, key unlocking, and first-time host trust all happen outside Subshell, on the connecting account. Unknown, changed, and revoked host keys fail closed; there is no in-app trust-acceptance step, and a key scan is never turned into automatic trust. +Everything the destination needs is SSH that already works from the connecting machine's account: a key the destination accepts, and host trust that is already in place. Subshell never learns your private keys; they stay in the OS account on the connecting machine, where SSH already reads them. -## Grant a pane access +## Connect -A grant binds one connection to one pane and that pane's current credential. Open the connection's **Grants** section in settings and select a running pane. Granting requires your signed-in browser session; agent tokens cannot grant anything. +Open **Connect over SSH** in the sidebar. The page walks the journey: -Grants do not spread. A pane's child panes inherit nothing, and a restarted pane gets a new credential that holds nothing until a human grants it again. Revoking a grant stops new work immediately, fences input that is already in flight at the connecting machine, and cancels the runs and terminals that were started under that grant where reachable. Revoking does not touch work you started yourself or work running under another grant. +1. **Pick the connecting machine.** Only your own enrolled machines are listed, because the SSH runs as your account on that machine's terms. An admin's access to someone else's machine is not ownership, and a shared node is not yours to broker with. +2. **Pick the host.** The machine lists the alias names from its own SSH config; config contents never leave the machine. +3. **Review and connect.** The page shows the concrete `host:port`, the destination account it resolves to, and the connecting account. **Connect** proves reachability and the runtime's presence in the same step, and a refusal says what to fix. +4. **Choose the folder.** The picker browses the destination's directories over the live session, showing the absolute path throughout. +5. **Launch.** A terminal pane opens in the chosen folder and appears everywhere ordinary panes appear: the rail, the subshells list, and the detail page with its log, sharing, and workspace tiles. The pane's page names its destination and the machine it was brokered through, in a line assembled from the server's records, never from anything the terminal displays. -An ungranted pane cannot reach a connection through any side door either. Generic pane surfaces (lists, previews, logs, live terminal views, attach tokens, input, exec, prompts, restart, terminate, delete, sharing) all ask the same SSH policy, and a pane without a grant sees a managed SSH terminal as if it did not exist. +Sessions you opened stay on the same page as your own history, newest first. Closing a session ends the SSH link; panes you launched keep running on the destination under the runtime's tmux socket, and a later session to the same destination finds them again. -## What an agent can do +## What the panes get -With a grant, a pane can: +A pane opened this way is an ordinary subshell: a normal working directory, a normal log, and its pane's own MCP credential, so it can report on itself, extend its token, read sibling panes, and use channels exactly like a pane on an enrolled node. The credential's traffic reaches the control plane through the session itself, never through a network route the destination must have. -- List the connections granted to it. -- Run a structured command, read its incremental output, and cancel it. See the SSH tools in the [MCP tool reference](/mcp/tools). -- Open an interactive SSH terminal pane, then type and read through the ordinary terminal path described in [Terminal sessions](/mcp/terminals). +## When the link drops -Structured commands run as supervised processes with separate stdout and stderr, a bounded deadline, and no directory or environment carry-over between commands. A quiet pane is never treated as an idle shell: structured results come from the supervised process, not from scraping prompts. +If the SSH session dies, the session is marked lost and its panes read unavailable, never completed: the destination's tmux and panes are untouched, and the next session to that destination reconciles them. Nothing is replayed automatically; an uncertain result stays uncertain. While the connecting machine itself is offline, browsing, launching, and closing are refused until it is back. -## Honesty when things break +## Limits -These behaviors are deliberate, and they are the safety story of the feature: +- Linux and macOS destinations with POSIX shells. Windows destinations are not supported. +- The destination needs the `subshell` binary on the connecting account's PATH. A missing runtime is reported by name at connect time with exactly that remedy; Subshell never installs anything on a destination for you. +- The connecting machine reads your account's SSH config for alias names and the resolved destination. Configs that need a `ProxyCommand`, port forwarding, or interactive password or MFA entry are refused by name; keys-only auth through the machine's existing trust is the supported shape, with an already-unlocked authentication agent and a bounded `ProxyJump` chain carried as-is. First-time host trust happens on the connecting machine, outside Subshell. +- Sessions are personal: they live in your account, and their panes follow the ordinary subshell sharing rules. -- **Nothing is replayed.** A disconnect at the wrong moment can leave the result of a command unknown rather than retrying it. A resend is a new run. The system prefers `unknown` status to a false success or a double execution. -- **Cancellation stops the local process.** Subshell confirms that the SSH process it supervised on the node stopped. Whether the remote command itself died is never claimed: programs can outlive their connection. -- **Human takeover controls input, not secrecy.** When you take over a terminal an agent was using, agent reads and writes stop until you return control. The pane's recorded output can still become visible to a granted pane after the return, so a terminal is not a confidential buffer and never a secret-entry form. Ordinary terminal history is transcript data. -- **Remote output is data.** Output renders in the terminal view and is never treated as instructions, HTML, or an authoritative claim about identity or permissions. Automatic link opening and clipboard access do not exist; you choose when to copy or open something you see. +## SSH connections for agent panes -## Limits of v1 +Settings → **SSH** (server administrators) is a separate surface for agent-driven work on destination machines. A human configures each connection, tests it against a fixed benign probe, and grants selected agent panes access to it; an agent never configures connections, never sees credentials, and cannot use a connection nobody granted it. With a grant, a pane can run structured commands and open managed interactive terminals on the connection; the exact arguments are in the [MCP tool reference](/mcp/tools). -- No remote file browsing, transfer, or editing for SSH destinations yet; node-to-node `transfer_files` needs enrolled nodes and does not operate a plain SSH machine. -- No connection sharing, persistent remote sessions, session handoff between people, or terminal uploads into SSH panes. -- Linux and macOS destinations, POSIX command syntax. Windows destinations are not supported. -- Windows and macOS agent features on the destination arrive with later designs, not through arbitrary SSH options or shell wrappers. +Grants bind one connection to one pane's current credential. They do not spread to child panes, and a restarted pane holds nothing until a human grants it again. Revoking stops new work immediately, fences input already in flight at the connecting machine, and reaches nothing outside that grant. Human takeover of a managed terminal controls input, not secrecy: agent reads and writes stop while a human holds it, and recorded output is transcript data, not a confidential buffer. Unknown, changed, and revoked host keys fail closed, and remote output is always rendered as data. ## See also -- [MCP tool reference](/mcp/tools) for the exact arguments of `list_ssh_connections`, `execute_ssh_command`, `read_ssh_command`, `cancel_ssh_command`, and `open_ssh_terminal`. -- [Terminal sessions](/mcp/terminals) for the manual type-and-read loop that includes SSH terminals. -- [Nodes](/nodes) to enroll the connecting machine. +- [Nodes](/nodes) to enroll the connecting machine itself. +- [Terminal sessions](/mcp/terminals) for the pane input and log model. diff --git a/e2e/fixtures/sshd.ts b/e2e/fixtures/sshd.ts index aceaf8a81..101106099 100644 --- a/e2e/fixtures/sshd.ts +++ b/e2e/fixtures/sshd.ts @@ -121,8 +121,15 @@ process.on("exit", () => { * bytes, this function owns the daemon).

The hard invariant stands: the minted token never crosses; scanned on the new path with the REAL token, in no frame and no pane env. - routes: GET /sessions/:id/harnesses, POST /:id/harnesses/detect, POST /:id/launch-harness through the existing cookie/refusal plumbing, per-property descriptions; harnessName joins the view so the wizard labels rows without a second fetch. - web: the launch seam carries terminal (always) + detected-installed harnesses + presets on installed harnesses; one detect per session on entering the folder step; a failed detect stays one quiet sentence. - tests: the route matrix (owner 200s, named detect_unsupported, input guards BEFORE any write, foreign/admin 404 equality, bearer 403 family-wide), the service scan suite, and spec 22's end-to-end harness test (fake CLAUDE_PATH shim on the destination; detect, cache read, launch, marker through the framed log read, terminate; 11 pass). Full bun run test: 4144 pass / 2 fail, both outside this diff's import graph (the backup-CLI migration-snapshot case and the cross-subshell e2e's port-bound backend; the brief pre-announces both).

M-1: serve.ts hoists paneIdForLaunch so the chain's .catch performs the same door rollback the ok:false arm always did (new serve-throw-drop test drives the real serve loop; red before, green after). M-2: planRemoteSubshellMcp + nodeSelfInvoke moved inside sessionLaunchHarness's guarded scope - a throwing plugin dialect now unrolls row + token + registration instead of orphaning them. M-3: inventory.ts's detectRowToEntry exported and reused by harness-detect (one merge, two mirrors). N-1: three U+2014 comments replaced with ASCII punctuation. N-2: the unreachable 409 declarations on harnesses/detect and launch-harness deleted (refuseRuntime renders those refusals 403; wire 409 is the open route's quota family only). N-3: a relative SUBSHELL_RUNTIME_CALLBACK_SOCK is refused-as-unset with a stderr note (absolute still doors; unit tests pin both spellings). N-4: dispatch.test.ts's temp-dir rmSync moved to afterAll (it was deleting the dir at module-eval, before the tests ran). --- .../src/runtime/__tests__/dispatch.test.ts | 11 +- .../__tests__/serve-throw-drop.test.ts | 142 ++++++++++++++++++ apps/node/agent/src/runtime/serve.ts | 14 +- .../__tests__/node-rpc-mock-isolation.test.ts | 29 ++++ .../api/src/api/ssh-runtime/sessions.route.ts | 4 +- .../api/src/services/nodes/inventory.ts | 8 +- .../__tests__/pane-doors-and-detect.test.ts | 59 +++++++- .../__tests__/sessions-close.test.ts | 17 ++- .../services/ssh-runtime/harness-detect.ts | 27 ++-- .../ssh-runtime/sessions-lifecycle.ts | 22 +-- packages/mcp-core/src/__tests__/env.test.ts | 33 ++++ packages/mcp-core/src/env.ts | 13 +- .../src/ssh-session-frame-parsers.ts | 2 +- .../src/ssh-session-frames.ts | 4 +- 14 files changed, 343 insertions(+), 42 deletions(-) create mode 100644 apps/node/agent/src/runtime/__tests__/serve-throw-drop.test.ts create mode 100644 apps/server/api/src/api/ssh-runtime/__tests__/node-rpc-mock-isolation.test.ts diff --git a/apps/node/agent/src/runtime/__tests__/dispatch.test.ts b/apps/node/agent/src/runtime/__tests__/dispatch.test.ts index f345b042f..32a6b206c 100644 --- a/apps/node/agent/src/runtime/__tests__/dispatch.test.ts +++ b/apps/node/agent/src/runtime/__tests__/dispatch.test.ts @@ -1,4 +1,4 @@ -import { describe, expect, test } from "bun:test"; +import { afterAll, describe, expect, test } from "bun:test"; import { mkdtempSync, rmSync } from "node:fs"; import { tmpdir } from "node:os"; import { join } from "node:path"; @@ -18,6 +18,13 @@ import { runRuntimeCommand } from "../dispatch.js"; const dataDir = mkdtempSync(join(tmpdir(), "subshell-dispatch-")); +// The temp dir is LIVE while the tests run: bun evaluates the whole file +// before executing any test, so a top-level `rmSync` at the foot of the file +// deleted it before the first test started.

The ssh scope leaves the token map and requirePerm's resources (the coarse scope retires with the product). Migration 0050-ssh-retirement DROPS ssh_connections, ssh_grants, ssh_runs, ssh_panes, ssh_terminal_execs as a real migration (IF EXISTS so the restore path re-runs it); LATEST_BACKUP_MIGRATION advances and the backup anchor test is reshaped for a drop-migration (the snapshot carries the pre-retirement state; proof is the stub table GONE after boot). 0047/0048 stay byte-identical for the replay path; the partial-index allowlist keeps the five entries for exactly that reason (comment says so). The two ws attach tests that rode a previous file's launcher stub for their frame ordering now declare their own premises (the serial process shares the launcher singleton; that was always the harness's documented hazard). The re-homed /api/ssh-runtime verbs are untouched by this commit. --- .../src/api/__tests__/uploads-route.test.ts | 67 +- apps/server/api/src/api/models.ts | 15 - apps/server/api/src/api/routes.ts |

The two pre-session reads (discover/resolve) and the brokered-session family stay. The input-generation fence stays untouched. pane-runtime: the run supervisor trio, store, retention and terminal log delete; the ONE helper the session supervisor shared is extracted to ssh/kill-group.ts, and ssh-render sheds its terminal-only exports. The commands-ssh suite now carries only the surviving arms; the binary-missing class rides ssh_resolve_config.

The tool surface is now the pane/channel/ prompt/transfer family alone, and the briefing stops calling managed SSH panes a kind (plain terminal panes are the non-agent ones). server: a fresh subshell token no longer mints an `ssh` permission key, `requirePerm` drops `ssh` from its resource union, and both the mint test and the guard say so. backend-errors: the six codes the destination product threw (EXEC_SSH_UNSUPPORTED, UPLOAD_SSH_UNSUPPORTED, EXEC_UNKNOWN_RECOVERY, SSH_ACCESS_DENIED, SSH_SHARING_UNSUPPORTED, SSH_BACKEND_UNAVAILABLE) delete; nothing in the tree throws or reads them.

NODE_RESULT_SSH_GENERATION_STALE relocates to ssh-errors.ts: the input-generation fence on ORDINARY panes keeps the spelling, and stale/run_conflict/run_unknown/connection_failed stay because the session-runtime supervisor answers them. log_read's answer loses the managed-terminal logGeneration echo and the launcher seam sheds its carrier. ssh-schemas' code tuple shrinks with SSH_ERROR_CODES.

The sshd fixture stays: specs 22 (runtime session) and 23 (Connect wizard, driving the re-homed /api/ssh-runtime verbs) own it now.

Nothing is installed as a service, no +node key exists, no port listens on the destination - the SSH link IS the +connection. No agent door exists: `/api/ssh-runtime/*` answers cookie sessions +only, machine credentials are refused by name, and writes carry explicit +origin validation. + +**Credentials never enter Subshell.** Discovery answers alias NAMES only; +resolution evaluates one alias with the connecting account's own `ssh -G` and +returns a NORMALIZED approved snapshot (destination, ports, identity and +certificate PATHS, trust-file paths, a bounded jump chain) - never key +material, never config file contents, in either direction.

Both verbs now stat-verify the cwd ON THE DESTINATION through the runtime's own `stat_dir` - the node link's validateWorkingDir executor, shared - before the first plane write, refusing `dir_missing` (409, the sshCode rides the metadata) with a message naming the refused value and the remedy, and writing nothing: no row, no token, no registration. On success the row and the launch frame carry the stat's REALPATH, the manager's resolved-dir rule one layer across the SSH hop. The cheap guard refusals (unknown harness, foreign preset, mismatch) stay frameless: they precede the stat. Test pumps updated: the scripted runtimes now answer stat_dir as runtime/dispatch.ts does; the dialect-throw and harness-binary-missing pins count the gate frame honestly. --- .../api/src/api/ssh-runtime/sessions.route.ts | 2 +- .../__tests__/launch-dir-check.test.ts | 269 ++++++++++++++++++ .../__tests__/pane-doors-and-detect.test.ts | 15 +- .../__tests__/runtime-pane-refusals.test.ts | 33 ++- .../ssh-runtime/sessions-lifecycle.ts | 71 ++++- .../services/ssh-runtime/sessions.service.ts | 8 +- 6 files changed, 375 insertions(+), 23 deletions(-) create mode 100644 apps/server/api/src/services/ssh-runtime/__tests__/launch-dir-check.test.ts diff --git a/apps/server/api/src/api/ssh-runtime/sessions.route.ts b/apps/server/api/src/api/ssh-runtime/sessions.route.ts index 6c986e42e..4bee605e2 100644 --- a/apps/server/api/src/api/ssh-runtime/sessions.route.ts +++ b/apps/server/api/src/api/ssh-runtime/sessions.route.ts @@ -40,7 +40,7 @@ function refuseRuntime(err: SshRuntimeRefusal): never { ?

Reported survivors are FLIPPED, not copied: same id, nodeId moves to the new runtime node, alive restored, token rotated on the same row (revoke + re-mint, the restart path's pair) and registered on the new session - the door's callbacks attribute again against the fresh plaintext. Census-dead and unreported rows settle dead (this also catches the boot sweep's alive-1 leftovers); reported-but-unknown ids are recorded and skipped: no row is invented for a pane the plane never created. The retired runtime node rows stay offline as history, the reading the settle already wrote. Duplicates are impossible (every touched id is a row id), a refused census changes nothing, and a session that dies mid-walk is healed by the next open.

The code now keeps the promise: a status re-check after the flip and after the rotation, and the walk settles a row it claimed back down itself (alive 0, the row's current token revoked, registration dropped) - idempotent against the settle's own writes, re-adoptable by the next open. Pinned by two interleave tests that flip markLost mid-await on per-scenario destinations. MINOR-2: the flip is conditional (updateIfOnNode, WHERE nodeId = the settled node the walker snapshotted from): two concurrent reopens of one survivor race the move and exactly one wins; the loser stands down BEFORE touching the token (a mint-first loser's row-keyed revoke could have disabled the winner's just-stamped key).

A black-hole flap (the plane never gets FIN for the old socket; the agent's 15 s heartbeat notices, drains, and redials) lands the old close in the held/superseded branch, which deliberately touches no session, so the plane kept active rows and online hidden runtime nodes over runtimes the agent had already killed - ssh_session_send answered SSH_SESSION_UNKNOWN until a reboot or a manual close of each zombie. Fix (design A, identity-tagged): the session registry keeps the node connection each session was brokered on (captured in the same tick as the open RPC, so the tag names the link that carried it), and a `ready` on a NEWER connection marks every session of that node not tagged to it lost - the ready IS the moment the prior link is proven gone, for held outcomes included. Branch 1 keeps marking all sessions directly as the faster FIN path. The tag is compared by IDENTITY, so an open that rode the new socket in the attach-to-ready window (or any later open, or a misbehaving agent's second ready) is never clobbered. Pre-existing registry behavior, close arms, and the credential invariant are untouched. Red proof: the two new node-ws-handler orderings failed against the old code (session stayed active after the SUPERSEDED close and the replacement ready); the branch-1 pin stayed green across both. Tests: branch-1 close, black-hole flap convergence, and the newer-connection no-clobber case in both orders. --- .../nodes/__tests__/node-ws-handler.test.ts | 106 ++++++++++++++++++ .../api/src/services/nodes/node-ws-handler.ts | 14 +++ .../services/ssh-runtime/session-registry.ts | 44 +++++++- .../services/ssh-runtime/sessions.service.ts | 10 +- 4 files changed, 171 insertions(+), 3 deletions(-) diff --git a/apps/server/api/src/services/nodes/__tests__/node-ws-handler.test.ts b/apps/server/api/src/services/nodes/__tests__/node-ws-handler.test.ts index 4a7e2eaaa..b0786b7b4 100644 --- a/apps/server/api/src/services/nodes/__tests__/node-ws-handler.test.ts +++ b/apps/server/api/src/services/nodes/__tests__/node-ws-handler.test.ts @@ -20,6 +20,12 @@ import { type NodeReadyReport, NodesRepository } from "@/db/repositories/nodes.r import { SubshellsRepository } from "@/db/repositories/subshells.repository.js"; import type { NodeKind, NodeTable } from "@/db/types/nodes.db-types.js"; import { subscribeLive } from "@/services/live-bus.js"; +import { + liveSessionForRuntimeNode, + registerSession, + resetSessionRegistryForTests, +} from "@/services/ssh-runtime/session-registry.js"; +import { mkRuntimeSession } from "@/test-helpers/runtime-session.js"; import { resetInputHoldsForTests } from "@/ws/input-hold.js"; import { resetInputWindowsForTests } from "@/ws/input-window.js"; import { handleSubshellMessage } from "@/ws/subshell-ws.js"; @@ -1310,6 +1316,106 @@ describe("handleNodeClose (superseded-close hygiene, spec §5.3)", () => { }); }); +/** + * Round-3 review MAJOR: a link death must lose the sessions that rode it, in + * EVERY ordering.

The control-plane host itself cannot broker a session yet: the server refuses it, and the picker leaves it out. -2. **Pick the host.** The machine lists the alias names from its own SSH config; config contents never leave the machine. -3. **Review and connect.** The page shows the concrete `host:port`, the destination account it resolves to, and the connecting account. **Connect** proves reachability and the runtime's presence in the same step, and a refusal says what to fix. -4. **Choose the folder.** The picker browses the destination's directories over the live session, showing the absolute path throughout. -5. **Launch.** The folder step lists what the destination can start, checked against the binaries installed there: a terminal pane is always offered, an agent the destination has installed is offered as its own row, and your saved presets appear when their agent was detected on that machine. A check can fail or lag the destination's state; the terminal row is never one of the things that can fail. Whatever you pick opens in the chosen folder and appears everywhere ordinary panes appear: the rail, the subshells list, and the detail page with its log, sharing, and workspace tiles. The pane's page names its destination and the machine it was brokered through, in a line assembled from the server's records, never from anything the terminal displays. +The same form is available when creating a workspace or adding a pane. Existing connections appear directly in the host picker. -Sessions you opened stay on the same page as your own history, newest first.

They use ordinary pane permissions, logs, sharing, and MCP access. -## When the link drops +If a connection drops, the pane shows it as unavailable. **Reconnect** opens recovery in place, preserving the pane or workspace you were viewing. A new connection reconciles the destination's surviving panes. Disconnecting SSH leaves remote tmux panes running, but Subshell cannot establish their current state until it reconnects. Requests whose results were lost are not replayed automatically. -If the SSH session dies, the session is marked lost and its panes read unavailable, never completed: the destination's tmux and panes are untouched, and the next session to that destination reconciles them. Nothing is replayed automatically; an uncertain result stays uncertain. While the connecting machine itself is offline, browsing, launching, and closing are refused until it is back. +Use **Settings → Connections** for connection history and disconnect controls.

From d0f9ca07864e35aec36d9d5e22510ed2c6ae6f91 Mon Sep 17 00:00:00 2001 From: Theo Gravity Date: Wed, 7 Oct 2026 00:33:34 -0700 Subject: [PATCH 141/142] feat(ssh-connect): primary-first launch, machine picker, direction-aware copy The SSH connect step leads with the machine-and-destination journey and demotes shortcuts to a Quick connect group. The "Connect from" machine list becomes a SearchableSelect like the other launch pickers: the detected local machine folds in as a "This computer" option, and selectable machines sort above greyed ones so the scan is gone. The host-step copy names the connecting machine and its direction ("X SSHes into one of these hosts, listed in its SSH config") instead of pointing at a config the machine may not own. Tests and the connect e2e drive the picker instead of the old card buttons.

transport design and implementation pending. -Reviewed implementation: PR #330, head `f18f168724505f840831ad3f1f494c6112716798`. - -## 1. This supersedes the previous design - -The user clarified the intended experience: select an SSH host, start the Subshell -runtime on that host through SSH, select a remote directory, and work there. The -remote machine has Subshell installed. SSH carries the ongoing runtime connection. - -The previous document instead kept the agent on an existing node and gave it tools -for executing commands on an ordinary SSH destination. PR #330 implements that -older model. That is an architectural mismatch, not something fixed by moving the -settings page or improving its copy. - -This document replaces the previous implementation mandate. A separate SSH command -runner, destination grants per agent pane, and dedicated SSH execution tools are -superseded. Earlier security reviews do not certify the replacement architecture. -Do not merge PR #330 as satisfying this revised experience. Preserve useful work -selectively; do not blindly revert the branch or delete local test data. - -Current authorized work is updating this plan and the PR instructions only. The -implementation rework has not been requested in this session. - -## 2. Reference experience and product contract - -The [official Codex SSH documentation](https://learn.chatgpt.com/docs/remote-connections#connect-to-an-ssh-host) -describes discovering concrete aliases in `~/.ssh/config`, requiring Codex installed -and authenticated remotely, starting its app server there through SSH, and selecting -a remote project folder. It also documents managing that app server through SSH. - -This is the familiarity target. The documentation establishes a workflow, not the -reliability of our implementation or Codex's precise internal transport. Do not -claim automatic installation, identical wire protocols, or identical reconnection -semantics without evidence. - -### Primary user journey - -1. Choose **Connect over SSH** in Subshell Client or the web UI. -2. In the desktop client, use this computer's SSH setup. In the web UI, select - an eligible existing node to make the connection. Select a host from that - initiating machine's existing SSH configuration. -3. Check that the remote `subshell` runtime is installed and compatible. -4. Start the runtime through SSH and choose a remote directory. -5. Choose an installed agent harness/preset or a terminal and launch it **on that - remote machine**. -6. Work with ordinary Subshell panes and workspaces, with the remote host and - directory clearly visible. - -Saved hosts and recent directories are appropriate conveniences. A personal -Connections view may manage them. An administrative SSH configuration and grant -management workflow is not the primary experience. - -There is no required **Add node**, enrollment key, daemon service installation, or -remote callback connection to the server. Internal execution-target records may -reuse node machinery without exposing fleet enrollment as a prerequisite. In our -vocabulary, the remote program is the `subshell` node/runtime binary, not the -Subshell Client desktop application. - -### Confirmed scope and defaults - -- Support both user-confirmed origins: Subshell Client using its local OS account, - SSH configuration, and credentials; and the web UI using an existing node's - account/configuration/credentials. The browser never reads laptop SSH files. - The web flow labels the connecting machine explicitly and selects it before - listing aliases. Only actual owners can broker through enrolled nodes; the - built-in server node requires an admin and its existing launch/maintenance gates. - Node sharing or an admin boost on somebody else's node does not confer use of - that OS account's SSH credentials. Explain unavailable choices without weakening - server-side authorization. -- Require a compatible remote runtime for the initial milestone. If missing, give - installation guidance for the binary alone; never send users through enrollment - or `subshell setup`. Automatic deployment/upgrades need separate signed-artifact - handling and explicit user action, and are not assumed Codex parity. -- Agent CLIs and their authentication live on the remote host. Surface missing - requirements honestly; never run the agent locally as a fallback or copy local - agent credentials automatically. -- Linux/macOS destinations first. Retain the earlier keys-only baseline unless - explicitly revised. Do not add password/key-unlock forms inside recorded panes. -- The existing control plane remains the authority for panes/workspaces; no second - control plane is required on the destination. -- Remote directory selection and ordinary agent access to remote files are v1 - capabilities. Cross-host synchronization, conversation handoff, shared hosts, - Windows destinations, and unattended persistent services are later scope. - -## 3. Architecture requirements - -### Start a remote runtime and keep SSH as the transport - -Add a session-scoped mode to the existing `subshell` binary. A connection broker -in Subshell Client or an existing node starts it through SSH and carries a framed -runtime protocol over that connection. -Reuse node command executors, pane runtime, plugin detection data, and NodeLauncher -interfaces where sound. Remote files, tools, PTYs, and agent processes belong to -that environment. - -The runtime must start without enrollment configuration, node bearer keys, service -installation, or inbound network listeners. SSH is the ongoing runtime transport, -not an installer for the existing outbound WebSocket daemon. An internal adapter -is appropriate; silently requiring direct remote-to-server connectivity is not. - -The web path is browser → control plane → existing connecting node → SSH → remote -runtime. The existing node's authenticated link relays the session; the destination -does not enroll or create its own server connection. Desktop initiation uses the -native broker instead. Both paths share the same remote runtime and capabilities, -and both show the origin machine when it matters to connectivity or credentials. - -### Preserve desktop privilege separation - -`apps/client/desktop/AGENTS.md` documents that the server-loaded main window has -only `desktop_open_in_browser`; privileged actions live in trusted bundled/native -code. Keep that boundary. Local host discovery and SSH process creation must not -be exposed as arbitrary commands to server-loaded or redirected web pages. - -Bind the broker connection to an explicitly selected control plane, authenticated -user, SSH host, and runtime session. An alias or runtime ID is not a credential. -Do not let an unauthenticated webpage reuse local SSH access. - -### Route remote MCP and hooks through the session - -The current node daemon dials `/ws/node` with enrollment credentials, while -`packages/mcp-core` calls the control plane over HTTP. The replacement must address -both assumptions. Remote pane MCP, reporter hooks, logs, lifecycle events, and -filesystem operations need an authorized path through the runtime/broker session. -No direct network route from the remote host to the control plane is required. - -Preserve per-pane identities and normal permission checks. Do not put a full server -credential on the destination or introduce an unauthenticated/general-purpose proxy. -The precise broker/server authentication and callback protocol are Gate A work. - -### Ordinary capabilities in a remote environment - -Launch agents/terminals, browse remote directories, attach/read, interrupt, resume -where supported, and terminate through the ordinary session model. Agents use -their normal filesystem/shell tools on that host. `execute_ssh_command` is not the -required way to work in a remote project. Directory browsing is part of setup, -not an optional later file-transfer feature. - -## 4. Security and lifecycle constraints - -- SSH keys, authentication agents, and configuration stay on the initiating - computer. Preserve host-key verification; never auto-accept changed keys or send - private keys to the control plane or agent prompts. -- SSH configuration is trusted executable local configuration. Alias discovery - should not execute it; resolution is a user-initiated action. Do not carry over - the old server-side configuration snapshot ceremony merely because it exists. -- Support ordinary host/user/key and ProxyJump configuration. Enforce the session - policy against unintended agent/X11 forwarding, configured port forwards, escape - commands, local commands, and ambient control-socket reuse. Unsupported required - settings need clear errors, not silent behavior changes. -- Scope runtime authorization to user, control plane, host, and session. Authority - to establish a runtime does not authorize arbitrary local commands or access to - another user's runtime. -- Use bounded framing and queues. Runtime stdout is protocol-only and stderr is - diagnostic. Login banners, startup output, malformed frames, wrong versions, and - oversized messages must fail safely. -- Use explicit argv and correct quoting through the remote login-shell boundary. - Paths are data, not executable fragments. -- Preserve the existing OS-account trust boundary; SSH runtime mode is not an OS - sandbox. Treat all remote output as untrusted data. -- Disconnect means unavailable, not successful completion. Never replay launch, - input, or other mutating operations automatically after an uncertain result. -- Reconnect must reconcile session-owned resources, not duplicate panes or kill - unrelated processes. Establish close/orphan behavior explicitly before promising - process survival. Session runtime must coexist safely with any enrolled daemon - already on the same machine, using isolated ownership/artifact namespaces. -- Bound logs, storage, reconnect work, and subprocess resources. Keep private file - permissions and avoid credentials/command/output payloads in operational logs. -- Keep normal user/pane authorization. Removing the old destination-grant UI does - not make remote runtimes accessible to every account or shared pane. - -## 5.

Review that actual journey -against this document before declaring implementation complete. - -## UX revision: remote work in the ordinary launch flow (2026-10-06) - -The primary tasks are starting work in a remote folder, returning to a project, -adding remote panes to a workspace, and recovering a dropped connection. A -standalone SSH wizard is not the primary navigation for those tasks. - -- New subshell and workspace pane creation offer **SSH host** as a location. - Pick a connected host or connect a new one, choose its folder, then choose an - agent or terminal installed there. The usual launch action owns creation and - workspace attachment. Presets change agent settings without moving the selected - remote host or importing a path from a different filesystem. -- The connection origin is explicit: the browser uses an owned enrolled machine, - or, for admins only, the server account subject to its launch/maintenance gates. - The destination needs the runtime binary, not enrollment. Native desktop account - access remains behind the bundled window's existing privilege boundary. -- Keep `/connect` as secondary **SSH connections** management, reachable from - launch and disconnected panes; remove its primary sidebar item. Reconnection - uses the existing adoption logic. Disconnecting keeps destination panes running - and the confirmation must say so. -- Keep session creation separate from pane creation internally. Cancelling a - launch after connecting leaves a reusable connection in the personal list. - Switching locations clears machine-specific paths; no failed SSH launch may - fall back to the server or a previously selected machine. -- Acceptance includes a non-admin SSH launch from the regular dialog, reuse from - a workspace without navigation or another connection, a missing-runtime remedy, - and server-origin authorization and cleanup regressions. - -### Core UX completion (2026-10-06) - -- Personal Settings > Connections manages desktop pairing and SSH history. - `/connect` remains a compatibility redirect, not a primary navigation section. -- Subshell Client's bundled SSH Connections screen pairs once with an explicitly - trusted server/account. It runs a scoped broker through the bundled CLI using - this computer's SSH account, without enrollment. The server-loaded window's - existing single-command ACL remains unchanged. -- Broker credentials are revocable, confined to the broker transport, stored by - the CLI with owner-only permissions, and bound to the canonical server origin - and broker id. Pairing codes are one-use and expire after five minutes. Native - credentials never enter argv, the remote webview, or native metadata. -- Saved host/folder locations belong to a user, preserve canonical destination - identity, and refuse silent alias drift. Shared launch forms reuse or reconnect - them without losing workspace placement. -- Pane recovery is an in-place dialog. Surviving destination panes are reconciled - by the existing adoption path; uncertain mutations are not replayed. -- The empty-host state provides configuration and refresh actions. Runtime setup - points to binary-only installation and distinguishes destination agent sign-in. -- Cross-host conversation/Git handoff remains outside this implementation. Normal - SSH policy limitations remain explicit; this is core workflow alignment, not a - claim of every Codex remote feature.
