The +wrapper owns loopback-only forward and return routes, so the receiving node can send +correlated replies without an SSH login back to the initiator, subject to the policy above. + +```bash +ocx message status --json +ocx message sessions --host worker --json +printf '%s\n' 'Please review and reply using the supplied route.' | + ocx message send --host worker --name reviewer --stdin --json +``` + +`--host` selects an exact enrolled alias or machine UUID. Reply commands include +the validated source machine UUID and thread UUID; source identity is resolved on +the source daemon, not guessed from a remote directory. Without sender context, +there is no invented reply command. Local commands without `--host` retain their +no-state/no-SSH/no-listener path. +The receiver validates the complete canonical envelope against the authenticated +machine and native message UUID, including reply host/command and standard peer guidance. +A peer cannot label the wrapper as another machine or omit its non-user-message warning. +Session names and thread IDs remain descriptive claims by that machine, not per-session authentication. + +Receiver-issued directional capabilities live in private messaging state under +`OPENCODEX_HOME` (or the default OpenCodex configuration home). They never appear in +normal command output, helper arguments, URLs or message envelopes. Mutual proofs +authenticate the actual WebSocket connection before native/body frames. A separate +health probe is not sufficient identity evidence. This is an OpenCodex gateway +protocol: raw `codex queue --remote` does not implement its authentication handshake. +The gateway uses the same native experimental `thread/queue/add` contract; it does +not alter Codex's own `--ws-auth`, configuration or native bearer-token listeners. +It exposes only loaded metadata and text queueing, not general app-server control. + +Status distinguishes enabled configuration, a running owner and initiated/leased +routes. Return leases expire after 25 seconds without refresh; they are not delivery +or processing receipts. Losing a route or changing owner configuration requires +explicit owner restart. Transport recovery never resends an uncertain message. + +```bash +ocx message hosts remove worker --json +ocx message disable --json +``` + +Removal revokes local admission first; an unconfirmed remote cleanup exits 3 and +requires removal on that peer too. Each outgoing removal uses an independent pinned-key +scratch file; a failure preparing that file still reports local removal and unconfirmed +remote cleanup. Scratch cleanup is attempted on both success and failure. Generated cleanup guidance uses +`hosts remove --transaction --json`; the transaction +guard refuses an old receipt rather than removing a newer enrollment. Ordinary removal +without this optional guard still removes the currently selected peer. +Disable retires the current owner generation; +dispatch refuses new work immediately, and the foreground owner notices changed +configuration within its ten-second maintenance interval. The sender checks local +authority again immediately before dispatch; revocation after dispatch cannot recall +an in-flight message or already accepted native work. A lost enrollment response retains one private +transaction: repeat the exact same add command to reconcile, rather than enrolling +under another name within the same enabled generation. Disable/re-enable or port +changes invalidate that recovery generation. Completed or revoked transactions cannot +restore a removed peer or erase another enrollment's recovery record. +If the saved local journal has malformed JSON, record shapes or field values, +`hosts add`, `hosts list`, `status` and `hosts abandon` refuse with +`invalid_enrollment_journal`. Its bytes are preserved for explicit operator recovery; +OpenCodex does not repair, replace or delete it automatically. `hosts add` sends no +enrollment control request in this case, although its preliminary host-key probe may run. +Unsafe storage or a busy mutation lock retains its separate error classification. +If a valid journal can no longer be reconciled, inspect `ocx message hosts list --json` or +`ocx message status --json` for `pendingEnrollment` (alias, transaction UUID and whether +its generation is stale), then explicitly abandon that exact local journal: + +```bash +ocx message hosts abandon --transaction --json +``` + +Abandonment works while disabled too. It leaves existing peers unchanged, does not retry +enrollment and exits 3 because remote cleanup is unconfirmed. Follow its cleanup guidance +on the remote node if an orphan enrollment remains. Stale journals are not silently deleted. +A full receiver returns `peer_capacity` without enrolling; free a slot and repeat the same +transaction or explicitly abandon it. Malformed or lost control replies remain uncertain. +Existing trusted 0755 configuration homes are accepted without chmod; messaging's own +subdirectory remains private. An immediate owner restart can replace a stale return lease +after the new endpoint authenticates and the old endpoint no longer authenticates within a +one-second check. A still-authenticating old endpoint retains its lease until expiry; +temporary unreachability can permit takeover, not replay. Unexpected tunnel loss visibly +retires the foreground owner; deliberate peer removal leaves unrelated routes running. +Crash mutation locks fail closed and need operator recovery; +the wrapper never guesses that an old lock is abandoned. +State and recovery-journal publication sync the file and containing directory before dependent +remote work; journal removal also syncs its directory. `remote_storage_unknown` (exit 3) means +the storage change's crash durability could not be confirmed: inspect state before explicit +recovery rather than automatically retrying. A safely readable journal with malformed JSON or +schema does not block peer removal, but is retained for operator recovery; unsafe storage and +failure to invalidate a matching journal still refuse removal. + +The foreground owner shares finite connection/request/helper/buffer limits across +all peers and rejects overload without an unbounded queue: enrolled peers together may +hold twelve authenticated connections, four more stay reserved for the owner's own +control, outgoing probes and renewal, and at most eight tunnel +children and two transient control/inspection helpers, ten total. Setup is bounded by +30 seconds across the whole selected peer batch. A final lease renewal precedes startup +success; final and periodic renewal batches have five-second deadlines, within the setup +deadline where applicable, and periodic maintenance runs every ten seconds. +Cancellation stops only owned +SSH helpers/listeners; it leaves Codex daemons, threads and unrelated proxies alone. +Cleanup joins withdrawn tunnel routes too. Direct-child exit and natural pipe EOF must +both settle within the three-second cleanup ceiling; otherwise cleanup is incomplete and +the helper reservation remains charged. Cancelling retained pipes does not prove descendants +exited.
