request failed" / "shell request failed"
runTuiSession awaited audit.create() (a Redis round-trip) and then
accessibleHosts() (a directory API call) BEFORE calling runTui(), which
is where the pty/shell/exec/subsystem listeners actually get attached to
the session. The client sends its pty-req and shell requests immediately
after opening the session -- if either await took long enough for those
requests to arrive first, ssh2 auto-rejects any channel request with no
listener (CHANNEL_FAILURE), which is exactly what OpenSSH reports as
"PTY allocation request failed on channel 0" / "shell request failed on
channel 0". The connection then just sat there, since nothing was left
to drive it.
runGrammar already has this exact fix (see its own comment); runTuiSession
never got the equivalent treatment. Fixed the same way: register the
session listeners synchronously, before any await, by having runTui take
a Promise for the hosts list instead of the resolved list -- the shell
handler awaits it internally once the client actually sends a shell
request, which by construction happens only after the listener already
exists.
Verified: publickey auth against a real deployment succeeds (confirms
the earlier ldaps:// fix holds), and the failure reproduces with the
exact reported error strings for a bare `ssh user@host` (TUI/picker mode,
no target) connection. Full suite: 50/50 passing, no regressions.

- Add standalone.enabled config flag to switch between LDAP+SSO and
ORM-backed backends without changing the production code path
- New ORM models: StandaloneUser (uid, passwordHash, sshPublicKeys,
groups) and StandaloneHost (slug, displayName, kind, metadata)
- user_file.js and hosts_file.js implement the same interfaces as the
LDAP client and accessibleHosts() respectively
- models/user_ldap.js and utils/access.js become conditional facades
that delegate based on conf.standalone.enabled at require time
- Zero changes to ssh_server.js core logic, bridge.js, key_inject.js,
tui_picker.js, or any other consumer
- Fix ssh_server.js: use ?? instead of || for listenPort (0 is falsy)
- Fix ssh_server.js: register session listeners before awaiting
audit.create() so client exec/shell requests aren't rejected
- Patch StringField.toSequelize() and IntegerField.toSequelize() to
pass through primaryKey (the ORM's UUIDField already does this)
- 47 tests pass (24 existing + 15 new unit + 3 existing integration
+ 5 new standalone integration)
- Defaults to SQLite; any Sequelize dialect works via conf.orm

An SSH jump host that authenticates users against the shared LDAP
directory, authorizes them from the SSO Manager's inventory graph, and
bridges them to downstream hosts — auditing everything.
- Username-grammar routing (uid_-_target@jump) + interactive TUI picker
- Inbound LDAP auth (publickey / password with off|local|all policy)
- Directory-driven access (LDAP groups x /api/discovery/resources?group=)
- Per-user key injection into sshPublicKey, connects downstream as the user
- Shell / exec / SFTP-subsystem bridging (WinSCP works)
- Web UI + HTTP API (:3002) for audit + metrics; LDAP-admin gated
- Packaged like proxy: ops/install.sh + systemd, all-in-one Docker, compose
- Tests: 23 unit + 3 integration (node --test), all green
