Browser login — the auth key is now optional on both platforms. When the
embedded node starts with no key, TailnetNode asks the backend (LocalAPI
backendStatus — IPN state, deliberately not filesystem heuristics: tsnet
writes logs and a machine key on every start, registered or not) whether a
login is needed, triggers login-interactive, surfaces the auth URL through a
new statusStream()/.needsLogin, and waits for Running (4-minute deadline,
generation-fenced against stop/restart). The Mac auto-opens the login page
from Settings ▸ Remote and shows a re-open button; the iPhone auto-opens only
during user-initiated pairing (a background reconnect that suddenly needs a
login must not eject the user to Safari — Settings ▸ Tailscale carries the
link). The remote-access toggle now reflects the in-flight start instead of
snapping off for the whole login window, and toggling off mid-start is
honored at both commit points (before and after host.start).
LAN↔tailnet fallback — picking Tailnet now keeps LAN on too: the host runs
both listeners under a new CompositeSyncListener (merged accept stream; one
child ending doesn't end the rest) and the pairing QR carries both hints.
The phone builds an ordered candidate chain — LAN first (QR hint or Bonjour),
tailnet second — and walks it on pair and reconnect, so a phone that leaves
the Mac's Wi‑Fi rolls over to the tailnet and rolls back when it returns.
A per-channel 4s connect guard (readiness-checking, bound to exactly its
channel) keeps a stale LAN hint from hanging the chain; a stale-client guard
in consume() keeps a replaced client's tail events from advancing it; chain
exhaustion during pairing lands in a terminal failure instead of spinning on
"Connecting…"; routine pre-fallback handshake errors no longer flash the red
error bubble. "Connected · LAN / Tailnet" shows whichever transport won.
Multi-agent review: 11 confirmed findings (incl. the login gate being dead
code via tsnet's eager state-dir writes, and two connect-timeout races), all
fixed and re-verified. Suite green (24 sync-related tests incl. 3 new
CompositeSyncListener tests); macOS + iOS builds clean.

A real iOS Xcode app (ios/NucleicRemote) linking the NucleicProtocol SwiftPM
library as a local package. Builds for the iOS 27 simulator and launches to the
pairing screen.
- Transport: NWFrameChannel (NWConnection) + LANDiscovery (Bonjour _nucleic._tcp).
- Engine: drives NucleicProtocol.SyncClient (Noise XXpsk0 pair / IK reconnect,
hello/welcome, HostMsg→Event stream).
- State: RemoteStore (ObservableObject) — the single on-device projection of host
state; IdentityStore persists the device identity (Keychain) + pinned host.
- UI (UX_IOS): attention-first SessionsView, SessionDetailView (transcript/diff +
status-driven action area / composer), ApprovalCardView with Face ID gate on
high-risk approvals + allow-always menu, PairingScannerView (AVFoundation QR),
SettingsView, connection chip. Same status glyphs/semantics as the Mac.
Add-iPhone QR display + server start live on the macOS side (follow-up); push /
Live Activity are M5 (needs the relay). gitignore keeps this .xcodeproj despite
the blanket *.xcodeproj rule.
