m3ultra afad68b114 Lane D R28 (v5.1): instrument LOD — KILLED with the measurement (ledger #4)
E: STOP — do not build the _lo variants. That work is unnecessary; the item is dead.

The oldest tri item on the books, killed under the wind-sway rule attached to the brief
("if the measured win is <20k tris in practice, KILL it with the measurement").

MEASURED, from the shipped depot GLBs: each of the five instruments is exactly 14,000
tris; band + amp on stage = 70,000. On paper a 3-4k _lo each "saves" ~52k, clearing the
20k bar easily.

But the rule says IN PRACTICE, and the brief named the reason — "interiors are
close-quarters". So I measured the rooms an LOD would have to fire in (live, all three
venue archetypes, interiorMode driven by hand since rAF is throttled):
  pub        9.7 x 9.7m, diagonal 13.7m, 12522 tris, 38 draws
  band_room  8.9 x 9.6m, diagonal 13.0m, 11699 tris, 35 draws
  rsl        12  x 9.4m, diagonal 15.2m, 15115 tris, 38 draws  (the biggest)

VERDICT: practical win = 0 tris. A player can NEVER be more than 15.2m from the band —
corner-to-corner in the largest venue, and the stage sits at one end so the real max is
shorter. An LOD is a distance trade; inside a <=15.2m room the band is never small — it
is the subject of the gig and of F's tour money shot. Any sane threshold (15-25m) never
fires; an aggressive 8m one fires in half a room at a distance where a 3-4k _lo is
visibly worse with no perceptual cover. The win isn't "small", it's STRUCTURALLY ZERO —
the distance an LOD needs does not exist in this game. Off the backlog forever.

No budget motivates it either: a venue interior is ~12-15k tris, ~85k with the band —
inside the 200k stress ceiling E's R22 tri diet restored, at 35-38 draws vs <=350.

SIDE-OBSERVATION for E (not a proposal, no breach motivates it): all five instruments
are EXACTLY 14,000 tris — a decimator target, not a measurement of the objects. A mic
stand does not need 14k. If instrument tris ever do drive a real breach, the lever is a
flat re-decimation by object complexity (mic stand -> ~1k), which beats any LOD because
it needs no distance. Filed so the next tri hunt starts from it.

Spike 1 (ledger #1) pending E's lean.glb — look.glb has landed, lean.glb not yet.
