Say which machine a session is on, and which one is here

[karngyan]

Why

Machines take their name from os.Hostname when they join a relay, and a hostname is not a string anybody has memorised. On a fleet of more than one that leaves two questions open on the screens that matter: which machine is this session on — answerable, but only in the sessions list — and am I looking at the box in front of me, which nothing answered at all.

What

Two marks, one shared component (machine-mark.tsx), so the glyphs mean the same thing wherever they land:

• a desktop for the machine this browser is running on
• the Cloudflare cloud — the mark this UI already uses for remote access, in the same orange — for a machine reached through the relay

Where they show:

• Sessions list: on machine group headings, beside the fold toggle rather than inside it, so the control keeps its own accessible name; and on every row's machine badge, ahead of the name.
• Terminal: a new chip in the corner column, above the tag strip. The tags and the chip now share one right-edge column, which is what carries the position the tags used to carry themselves.

All of it is behind the rule the machine column already follows: a fleet of one is not a question, so a single-machine screen is exactly as bare as it was.

"This machine" is not LOCAL_MACHINE_ID

local means the machine this tab rides, which on a relay origin is a box in another room reached exactly like the others. So the loopback flag the router already threads into the fleet is exposed as useLoopbackTab(), and a relay tab (a phone, say) marks every machine — its own ride included — as remote. That is the truth from there, and a house on any of them would point somewhere the reader is not.

Tests

machineOfGroup (both levels of a two-cut key), the table's marks and their absence, the terminal chip's placement/wording/absence, the sessions route across loopback and relay tabs, and machineChipFor for the route rule that decides whether a chip exists at all.
