Closes #6415.

Problem

A host only becomes visible server-side via host.ensure, called once inside connectRelay at host-service boot. If that call failed (expired token, transient API failure, org mismatch), the failure was swallowed: the service kept running and passed local health checks, superset hosts list returned [], and every automations create variant failed with a bare Error: Not found — the CLI blanked the server's "Host not found" message, and on CLI-only installs the daemon's stdio was ignored, so the registration error was recorded nowhere.

Full diagnosis + verified before/after repro: #6415 (comment)

Changes

Make the failure self-diagnosing

• cli-framework/runner.ts: NOT_FOUND now prints the server's message (extracted a testable formatError)
• trpc verifyHostAccess: NOT_FOUND message names the host — Host <machineId> is not registered in this organization
• cli resolveAutomationTarget: preflights the target host against host.list in all modes (including the session-mode early return that previously validated nothing) and raises a CLIError with a restart hint

Stop registration failing silently

• host-service connectRelay: retries host.ensure with capped backoff (30s → 5min, indefinitely) instead of one-shot; outcome recorded in a registration-state module
• host-service health.check: now returns cloudRegistered / registrationError
• cli status: warns when the host is running but not cloud-registered (falls back to the host.list lookup for older host-services)
• cli spawn: daemon stdio → per-org host-service.log (same rotation convention as desktop; openRotatingLogFd moved to @superset/shared/rotating-log and reused by both)

Verification (E2E on the dev stack, isolated Neon branch)

Staged the reporter's exact state (deleted the v2_hosts row while the host-service kept running) and drove the real CLI + desktop UI over CDP:

• CLI session-mode create: Error: This machine (host 300d922f…) isn't registered with the cloud + Hint: Restart the host service… (was: Error: Not found)
• CLI --host create: Error: Host 300d922f… is not registered in this organization + Hint: Run: superset hosts list
• Desktop UI create (bypasses CLI preflight): server 404 body and inline dialog error both show the new named message
• Real built host-service (ELECTRON_RUN_AS_NODE) with an invalid token: logs failed to register/connect relay (retrying in 30s): … Failed to mint JWT: 401, health.check returns {"cloudRegistered":false,"registrationError":"Failed to mint JWT: 401"}
• superset status against that instance:

  Superset: Kiets-Spaceship (300d922f…) running (pid 75054, up 18 seconds)
  Warning: not registered with the cloud for Superset (Failed to mint JWT: 401) — hosts list and automations won't see this machine
  Hint: check host-service.log; registration retries automatically, or run: superset stop && superset start
  

• Daemon spawn with a stub binary: child stdout/stderr land in ~/.superset/host/<org>/host-service.log
• Recovery: restored registration → the same create commands and the same UI dialog succeed

Tests: formatError unit tests (mutation-checked), resolveAutomationTarget preflight tests. bun run typecheck clean, bun run lint clean. Pre-existing bun test packages/cli failures (execFileSync mock leak) exist on main and are unrelated (5 fail on HEAD, 4 with this branch).

Summary by cubic

Surfaces host cloud-registration failures instead of a silent “Not found” and keeps retrying registration with backoff. Previously host.ensure failures were swallowed, the host looked healthy locally while hosts list returned [], and automations create failed with a blank “Not found”; now the CLI prints the server message, status reports registration state, daemon output is logged, and the retry timer no longer delays shutdown.

• @superset/cli-framework: extracted formatError; stop blanking NOT_FOUND messages; add login hint for UNAUTHORIZED.
• @superset/trpc: automation.verifyHostAccess returns NOT_FOUND with Host <id> is not registered in this organization.
• @superset/cli: resolveAutomationTarget preflights host against host.list in all modes and raises a CLIError with restart guidance; status warns when running but not cloud-registered, falls back to host.list for older host-services, and clears the health-check timeout on errors.
• @superset/host-service: connectRelay retries host.ensure with capped backoff (30s → 5min) until success and unrefs the retry timer; track registration state; health.check returns cloudRegistered and registrationError.
• @superset/shared: new @superset/shared/rotating-log used by CLI daemon spawn to write stdout/stderr to per-org host-service.log; removes the duplicated desktop helper.
• Tests: unit tests for formatError and resolveAutomationTarget preflight; health smoke tests updated for new fields.

Rollout

• No migrations required. Ensure all apps consume @superset/shared/rotating-log.

Structured CLI error formatting packages/cli-framework/src/runner.ts, packages/cli-framework/src/runner.test.ts	Separates error formatting from process handling and preserves server NOT_FOUND messages with fallback text.

Round-2 verification: blast-radius sweep of everything this touches

Swept all consumers of the changed surfaces and E2E-tested each on the dev stack. Two real issues found and fixed in follow-up commits:

1. smoke.integration.test.ts asserted the exact health.check shape — would have failed CI on the new fields. Updated; full host-service integration suite green (306 pass).
2. The retry backoff timer could extend host-service shutdown — the desktop entry's SIGTERM handler relies on event-loop drain with an unref'd force-exit. The retry timer is now unref()d (061135e4a); the HTTP server keeps the process alive between retries, so retries still fire. Verified: SIGTERM mid-backoff exits within the designed 3s grace window.

Verified non-breaking everywhere else:

• Recovery without restart (new property worth knowing): host-service in the retrying state with an invalid token → dropped a valid auth-token.enc into its home → next retry minted a fresh JWT from disk and registered; health.check flipped to cloudRegistered:true. The old code required a restart; now auth recovery self-heals.
• All other health.check consumers (CLI spawn poll, desktop pollHealthCheck, CDP scripts) only check res.ok — additive fields are safe. tRPC clients tolerate extra fields.
• formatError NOT_FOUND passthrough improves every endpoint, not just hosts — e.g. automations get <bad-id> now prints Error: Automation not found (was Error: Not found). Grepped for callers relying on the old blanked string: none. The other NOT_FOUND messages that now reach users (v2-host.ts "Host not found in this organization", CLI resolve.ts "Host not found: ") are already well-formed.
• Desktop coordinator log path: dev mode pipes child stdio to the dev terminal by design (verified the child boots and logs with the moved @superset/shared/rotating-log module); the prod file path is exercised by the coordinator unit tests (35 pass) and a real spawn test of openRotatingLogFd from its new location.
• Sherif/exports: new @superset/shared/rotating-log export passes Sherif.

One known behavioral nuance, intentionally accepted: the CLI preflight reports "not registered" for a host that exists but which the caller lacks a v2_users_hosts grant for (shared-host second-user case), since host.list inner-joins the grant table. The hint (superset hosts list) still shows the user exactly what they can target, and bypassing the preflight yields the server's FORBIDDEN "You don't have access to this host".
