The office keeps its lights on, and something walks around under them

Archived

**Lights.** A sited office follows the real sun, and the real sun spends
half its time below the horizon — which was producing a technically
correct and completely useless picture: an unlit floor plate at midnight
in a building whose whole premise is that you can see who is at which
desk. `luminaires.ts` brings the diffusers up as the sun goes down and
reports one scalar for how much interior light there is; `withHouseLights`
adds it to the rig. CONTRACT §4's rule that a fitting emits no light is
kept in full — nothing here is a light source, and the rig still has one
owner.

**And they notice you.** A fitting within four metres of somebody walking
underneath brightens and fades back as they leave, which is what an
occupancy-sensed floor actually does at night. They are one `InstancedMesh`
sharing one material, so `emissiveIntensity` cannot vary between them —
`instanceColor` can, but three multiplies it into the diffuse term only, so
six lines of `onBeforeCompile` carry it into the emissive term as well. The
alternative was one mesh per fitting: forty draw calls of ceiling in a
building that spends about twenty on everything.

**Optimus.** A posable Gen-3 humanoid — eleven articulating joints, pale
shells over a dark frame, a black visor — with a walk cycle driven by
*distance travelled* rather than wall-clock, so the feet do not slide when
a robot slows down. Two per floor, derived from the pack's levels, so the
two-storey tower gets four and the hangar gets two without either pack
knowing robots exist. They wander between reachable points using
`Plan.blocked` — the collider the wall split already produces — and they
are deliberately **not** gated on `depth`: the build-time-exclusion rule is
about occupancy, and a robot is nobody.

**Starlinks stop being pixels.** The sixty-four nearest the centre of view
grow real geometry — a flat bus with ONE large solar array, which is the
actual signature and the thing everybody draws symmetrically and wrong —
fading in so there is no pop where a point becomes a mesh. Two draw calls.
The sun for their attitude comes from `solar.ts` and not from the rig,
because `atmosphere.ts` floors the light direction to keep the shadow
camera usable, and a sun ten degrees *down* is exactly the dusk geometry
that makes a pass visible.

**Aircraft** are airliners now — swept wings, nacelles, a fin — instead of
an arrowhead, still one shared geometry facing +Z as `flights.ts` requires.
**Clouds** drift over the board, driven by observed cover, lit by the rig
rather than by themselves.

Four modules were built by subagents and reviewed by another; every one
came back `needs-work` and the reviews were right. Fixed before wiring:

  - The walk cycle's arms were a quarter cycle out of step with its legs —
    the legs are cosine-shaped and the arms were on `sin`, so at the
    instant the left leg reached full forward the left shoulder was at dead
    neutral. Uncanny, and hard to name until it is pointed at.
  - Every Optimus shell used a `roundedBox` radius of 0.12–0.22, which that
    primitive turns into a near-circular cross-section — the figure was
    built out of lozenges, not panels. The rest of the library uses
    0.02–0.09.
  - The cloud material was `transparent` + `DoubleSide` without
    `forceSinglePass`, so three rendered it twice per frame *and* bumped
    `material.version` on each pass — rebuilding the program cache key
    forever, on the one layer that is fill-rate bound.
  - `starlinkMesh.dispose()` freed the geometries but not the
    `InstancedMesh`es, orphaning their instance buffers on every city
    switch.
  - The airliner's tailplane roots sat outside the tail cone and hung in
    free air over most of their chord.
