Summary

  • add --tailscale-serve-host / T3CODE_TAILSCALE_SERVE_HOST config support
  • centralize advertised startup URL resolution for Tailscale Serve, MagicDNS discovery, and HTTP fallback
  • use advertised HTTPS URLs for startup browser targets and headless pairing output
  • document the host override and fallback behavior in REMOTE.md

Verification

  • bun fmt
  • bun lint (passes with existing warnings)
  • bun typecheck
  • bun --cwd apps/server vitest run src/cli/config.test.ts src/startupAccess.test.ts

Note: bun run test was started, but the apps/server Vitest worker hung after other packages reported passing and was terminated. The focused server tests touched by this PR pass.

P2 Badge Fall back when Tailscale Serve is not configured

When --tailscale-serve is set on a Tailnet machine where tailscale status --json succeeds but tailscale serve --bg fails, this still advertises the MagicDNS HTTPS URL. The actual Serve setup error is swallowed in apps/server/src/server.ts lines 374-379 so the backend keeps running on HTTP, but the headless output/startup pairing URL now points clients at an HTTPS endpoint that was never configured. This should be gated on successful Serve setup or probed before replacing input.httpBaseUrl.

P2 Badge Gate advertised HTTPS on Serve success

When --tailscale-serve is enabled and tailscale status --json succeeds, this advertises the MagicDNS HTTPS URL even if the preceding ensureTailscaleServe call failed; I checked apps/server/src/server.ts, where that failure is caught and the server continues after only logging a warning. In that failure mode (for example tailscale serve --bg denied or unsupported while the daemon still reports status), headless output and startup links point users at a non-serving HTTPS URL instead of the still-working HTTP fallback.
