feat: remote host descriptors in config, and host-gated warnings - #275
Conversation
Projects and workrooms can carry an opaque `host` descriptor that every config writer round-trips. The app owns its schema; the CLI reads only whether a workroom's host is present (remote) and `state == "destroyed"`. - `list --json` reports `host` (additive, schema_version stays 1). Remote workrooms skip DirectoryMissing/VCSWorkroomMissing; a destroyed host reports the new HostDestroyed warning. - `add-project` refuses remote paths (RemoteProjectUnsupported). - `delete` and `delete-project` (all modes) refuse remote workrooms (RemoteWorkroomUnsupported), so teardown never runs against a local path of the same name and config never drops the only record of a remote machine. - RemoveWorkroom keeps a project that carries a host; `create` avoids names already in config. - Config.Read decodes with UseNumber so large integers survive. - App: TerminalTarget.unavailability distinguishes directory missing, remote and host destroyed; remote workrooms are never registered, watched or probed as local repos; app deletes refuse remote rows before any local cleanup; New Project sheet flags remote paths.

📝 WalkthroughWalkthroughThe CLI and macOS app now recognize host descriptors for remote workrooms and projects. List output reports those descriptors and identifies destroyed hosts.

startShippedDaemon returned as soon as the socket file existed, but the v2.0.0 daemon's bind() creates that file before listen(), so a connect in that window was refused (errno 61). Under a parallel make app-test this failed a different SessionShimCompatibilityTests case on each run. Probe with a frameless connect instead; the daemon reads EOF and drops it.

Exclude unavailable targets from persistent recovery.
TerminalSessions.restore only reconstructs inert tab state. PersistentSessionRecovery later calls ensureSurfaceCreated, which explicitly spawns a PTY without waiting for window mount. The TargetTerminalDetail guard does not cover this path.
A saved target can still resolve after its workroom becomes remote or its host is destroyed. The PR classifies those targets as unavailable but does not apply that boundary to recovery. The result is a hidden local PTY that can attach an existing session or run the lost-session fallback for a target that cannot be opened. It does not launch a new user workload.
Keep the restored tab state so it remains persisted, but exclude unavailable target IDs from recovery.

Valid, but deferred to #253 rather than fixed here. It is gap 4 in #253 (comment). No workroom can turn remote until something writes host, which #252 and #253 will do, so this path can't be reached yet. Recovery for a .directoryMissing target also predates this PR. The fix changes Core/Session/, which macapp/AGENTS.md rule 3 says needs its own adversarial review. It belongs with #253's reconnect work, whose acceptance criterion 3 exercises this same path, so I'm leaving this thread open until then.

@joelmoss, thanks for the context. Deferring this finding to #253’s reconnect work is reasonable. The .directoryMissing recovery behavior predates this PR, and remote recovery becomes relevant when #252 and #253 introduce host writers.
The finding remains open, as requested. No separate follow-up issue is needed because #253 already tracks it as gap 4.

… turn remote
Config.Read's dec.More() check accepted `{}}` and `{}]`, which
json.Unmarshal used to reject, so a later write would silently drop the
tail. Require a second decode to hit EOF instead.
Reload pruned workroomStatuses by sidebar membership, which includes
remote workrooms. The sweep no longer refreshes a workroom once it turns
remote, so its last local status kept tinting the row and its project's
badge. Prune by what the sweep probes.

What changes
Projects and workrooms can now carry a
hostdescriptor in config. The app owns what goes in it (OQ21). The CLI reads only two things from a workroom'shost: whether it is present, which makes the workroom remote, and whetherstate == "destroyed". Nothing writes ahostyet; #252 and #253 will.hostas it is. This is because config is held as an untyped map. A test covers each writer.Config.Readnow usesUseNumber, so large integers survive a read and a write. This change applies to every config read, not only remote ones.list --json. Each workroom and project now reportshost. The field is optional (omitempty) and only adds data, soschema_versionstays 1. A remote workroom no longer getsDirectoryMissingorVCSWorkroomMissing. A destroyed host reports a new warning kind,HostDestroyed.add-project. A remote path (host:pathorscheme://…) fails with the new error codeRemoteProjectUnsupported.RemoteWorkroomUnsupported. This applies todelete, interactive delete, the--with-workroomscascade, anddelete-projectin all three modes, not only--from-disk. Without this, the teardown script and the git/jj removal would run against a local path of the same name. A plain config-onlydelete-projectwould also drop the only record of a paid machine. Remote workrooms in the app: create, open and delete (Nightly only) #253 replaces these refusals with a real remote delete.RemoveWorkroomkeeps the project if it carries ahost. An explicitdelete-projectstill removes it. The design doc records this choice.create. It never reuses a workroom name that is already in config, because that would overwrite a remote entry.TerminalTarget.unavailabilityseparates three cases: directory missing, remote, and host destroyed.isMissingis now derived from it, so the existing guards keep working.RepositoryRouter.prepare,statusWorkItemsandselectedStatusWorkItem.SessionShimCompatibilityTests.startShippedDaemontreated the daemon as ready as soon as its socket file existed. But the v2.0.0 daemon callsbind(), which creates the file, before it callslisten()(SessionSocket.swift, lines 21 and 31 at v2.0.0). A connect in that window is refused withconnect failed: 61. Under a parallelmake app-test, this failed a different test in that class on each run. The helper now waits until a test connection succeeds. That connection sends nothing, so the daemon sees it close and drops it (handleConnectionat v2.0.0).Validation
