Blocks: #12, #13

From PLAN.md, section "Multiplayer track → S12".

Node sharing. Share geek with a second tailnet (a test account).
- What do Tailscale-User-Login/-Name/-Profile-Pic and WhoIs report
  for a shared-in user, behind serve and on direct connections?
- Can the ACL limit them to port 443?
Funnel.
- Is tailscale funnel on a second port usable for M15's invite flow?
- What headers arrive, given there is no identity?
- What are the rate limits?
Input attribution cost. Add a per-input index record
(offset, principal, len) to the M2 index. Measure index growth with the
full typing of a day of use, and with paste of 1MB.
"From now" sharing. Can a viewer's first snapshot be taken without
scrollback (screen only, via GHOSTSNP partial encode or the formatter), so
history before the share point never leaves the daemon?

Since M15 is superseded by #31 (control track), skip the Funnel part of this spike. Node sharing, input attribution and "from now" snapshots still matter for M12–M13.
