Scoping at 44830a0e puts 4b at 1,300-2,200 production lines (centred ~1,700)
plus ~2,500-3,500 lines of test work — 4-6x route 4a and ~2x route 2, the two
largest landings in this campaign, which took 4 and 5 review rounds. Split into
4b-1 (infrastructure, no behaviour change), 4b-2 (far branch), 4b-3 (teleport
and cell-less, with the ~739-line class deletions). 4b-1 stays separate
regardless of appetite for landings.
Corrects two errors in documents from yesterday:
AP-135 does NOT retire with 4b. Its own condition is retirement with the
free-fall sweep gate, which 4b does not touch, and its sites are the airborne
no-op branches — 4a-owned dispositions. The trap is that its two writes sit
inside OnPosition, which 4b rewrites heavily.
Retail has exactly ONE ConstrainTo on the remote arm (@0x00454272); all three
nonzero-returning MoveOrTeleport branches funnel through it. My route-4 scoping
implied a distinct remote-teleport arming site. There is none, so 4b must not
add a second one — the post-operation arm 4a introduced becomes the only arm.
Records a new failure mode 4b must not create: a DeferredCell park WITHDRAWS the
entity (InWorld false, Active cleared, clock suspended, residency dropped), and
Forget-on-every-accepted-Position kills the park without restoring any of it. If
the next packet classifies Interpolate, no placement runs and the remote stays
withdrawn indefinitely — invisible AND intangible, the #184 class through a
third door. Direction: refuse rather than park; the next packet is the retry,
because remote Positions are a 5-10 Hz stream.
Two transfer errors named explicitly so they are not repeated: do not port route
2's re-issue funnel (re-issuing a superseded pose is wrong for a repeated
stream), and do not port its ack machinery (retail's remote arm has no
SendPositionEvent).
Also records that remotePlacementRequired fires for every non-visible remote on
the graphical host — a routine hot path, not a teleport rarity — and that
deleting the legacy blocks removes the only handler for null/Rejected*, which
during the login window is every remote packet.
