karti	8fb85cd2e5	feat: give the boards a horizon, a sea that reflects, and a state worth flying over The wide shot, which is what an anonymous visitor actually lands on. The sea was `MeshLambertMaterial` — a material with no specular term at all, by construction — on a board where water is half the frame. It is now a low-roughness dielectric that reads `scene.environment`, with a runtime-generated tiling swell normal map sampled twice per fragment at two scales and two headings, so the sun breaks into a moving glitter path instead of a mirror point. An `onBeforeCompile` patch takes the body colour toward the deep value looking straight down and leaves it to the reflection at grazing, and walks roughness up past 1.6 board spans so the far water cannot shimmer. The swell spectrum is 1/k^2 and not 1/k because the first attempt was photographed: at 1/k every component carries the same slope, the shortest wave wins, and the sea renders as hard diagonal corduroy. A test holds it now. The board no longer ends in a diamond. The sea plane went from 1.8 board spans to 18, past the fog's far plane from anywhere the orbit reaches, and the sky is a world-space dome rather than a screen-space gradient. That gradient was wrong in a way dusk made obvious: the sunset band was painted along the bottom of the picture, under the board, while the true horizon at the top of frame stayed zenith blue. `daylight.ts` pinning the horizon stop to the fog colour to hide the seam was a symptom of it. Terrain casts shadows. Left off before because double-sided terrain against a ~16 m-per-texel shadow map gives acne; `shadowSide = BackSide` is the cure, shot at four sun elevations down to +0.0 degrees to confirm no stippling. The caster is a stride-2 decimation appended to the same index buffer and swapped in by `onBeforeShadow`/`onAfterShadow` via `drawRange`: no extra draw call, a quarter of the depth cost, and indistinguishable from the full-resolution caster in a side-by-side crop. Stride 1 was measured at +65,566 triangles and would have missed the budget by ~47,000, so it was not shipped. California reads as California. It was a beige kite: the eastern edge one ruled line for five degrees of latitude, the south closing in a diagonal V, the whole south-east a featureless tan wedge. Now the coast runs to the Mexican border with San Diego on it, the eastern edge follows the Colorado and the Nevada diagonal, and the south-east is the Basin and Range — forty parallel desert ridges throwing shadows east, Death Valley as a white pan between the Panamints and the Black Mountains, the Salton Sea the one cool value for two hundred kilometres. The opening pose is retuned to the bigger board; the old 452/392 stand-off left a slab of empty ocean where the state should be. The aircraft were six pixels. Measured, by enlarging a screenshot 200% to find one at all — indistinguishable from a dead pixel, on a board whose entire claim is that the sky is live. They are airliners now, with planform and trail, and clicking one raises its card for a signed-out visitor. The Model X is off the wall. It stood at floor level outside a studio 188 m up a Transbay tower, reading as a car balanced on a parapet. The apron is now chosen from `site.elevation`, which the pack already carries — not from an office id, which is the bug class this repo already hit once when a door marker gated on `id === "sf"` and would have pinned the Los Angeles building to San Francisco. Also fixed, and nearly shipped: sea z-fighting dithered every flat piece of ground on the Bay Area and SoCal boards. And one test asserted an exact source line for the water material, so the better multi-line implementation failed it — it now asserts the property (dielectric, metalness 0, low roughness) rather than the author's first guess at formatting. Tests 964 -> 1015. California desktop 562/650 draw calls and 728,744/750,000 triangles — 2.8% of triangle headroom left, which is the number the next person should check first. No budget was raised.

feat: give the boards a horizon, a sea that reflects, and a state worth flying over

The wide shot, which is what an anonymous visitor actually lands on.

**The sea was `MeshLambertMaterial`** — a material with no specular term at all,
by construction — on a board where water is half the frame. It is now a
low-roughness dielectric that reads `scene.environment`, with a runtime-generated
tiling swell normal map sampled twice per fragment at two scales and two
headings, so the sun breaks into a moving glitter path instead of a mirror point.
An `onBeforeCompile` patch takes the body colour toward the deep value looking
straight down and leaves it to the reflection at grazing, and walks roughness up
past 1.6 board spans so the far water cannot shimmer.

The swell spectrum is 1/k^2 and not 1/k because the first attempt was
photographed: at 1/k every component carries the same slope, the shortest wave
wins, and the sea renders as hard diagonal corduroy. A test holds it now.

**The board no longer ends in a diamond.** The sea plane went from 1.8 board
spans to 18, past the fog's far plane from anywhere the orbit reaches, and the
sky is a world-space dome rather than a screen-space gradient. That gradient was
wrong in a way dusk made obvious: the sunset band was painted along the *bottom*
of the picture, under the board, while the true horizon at the top of frame stayed
zenith blue. `daylight.ts` pinning the horizon stop to the fog colour to hide the
seam was a symptom of it.

**Terrain casts shadows.** Left off before because double-sided terrain against a
~16 m-per-texel shadow map gives acne; `shadowSide = BackSide` is the cure, shot
at four sun elevations down to +0.0 degrees to confirm no stippling. The caster is
a stride-2 decimation appended to the same index buffer and swapped in by
`onBeforeShadow`/`onAfterShadow` via `drawRange`: no extra draw call, a quarter of
the depth cost, and indistinguishable from the full-resolution caster in a
side-by-side crop. Stride 1 was measured at +65,566 triangles and would have
missed the budget by ~47,000, so it was not shipped.

**California reads as California.** It was a beige kite: the eastern edge one
ruled line for five degrees of latitude, the south closing in a diagonal V, the
whole south-east a featureless tan wedge. Now the coast runs to the Mexican
border with San Diego on it, the eastern edge follows the Colorado and the Nevada
diagonal, and the south-east is the Basin and Range — forty parallel desert ridges
throwing shadows east, Death Valley as a white pan between the Panamints and the
Black Mountains, the Salton Sea the one cool value for two hundred kilometres.
The opening pose is retuned to the bigger board; the old 452/392 stand-off left a
slab of empty ocean where the state should be.

**The aircraft were six pixels.** Measured, by enlarging a screenshot 200% to
find one at all — indistinguishable from a dead pixel, on a board whose entire
claim is that the sky is live. They are airliners now, with planform and trail,
and clicking one raises its card for a signed-out visitor.

**The Model X is off the wall.** It stood at floor level outside a studio 188 m up
a Transbay tower, reading as a car balanced on a parapet. The apron is now chosen
from `site.elevation`, which the pack already carries — not from an office id,
which is the bug class this repo already hit once when a door marker gated on
`id === "sf"` and would have pinned the Los Angeles building to San Francisco.

Also fixed, and nearly shipped: sea z-fighting dithered every flat piece of ground
on the Bay Area and SoCal boards. And one test asserted an exact source line for
the water material, so the better multi-line implementation failed it — it now
asserts the property (dielectric, metalness 0, low roughness) rather than the
author's first guess at formatting.

Tests 964 -> 1015. California desktop 562/650 draw calls and 728,744/750,000
triangles — 2.8% of triangle headroom left, which is the number the next person
should check first. No budget was raised.

feat: tone-mapped render rig, studio devices, LA fidelity pass, UI overhaul

The build the studios needed, across eight workstreams and one strict file
partition.

**The render rig was the quality ceiling.** The renderer ran three's
NoToneMapping default while atmosphere drove the sun to 2.35 and assets set
emissives to 3.2, so every value above 1.0 hard-clipped to flat white — which is
why walls blew out and every fitting looked like a white rectangle. ACES filmic
tone mapping and an explicit output colour space land in `stage.ts`, and the
atmosphere intensity table and palette headroom are re-tuned against the new
curve rather than left tuned for the clipping we removed.

`engine/environmentRig.ts` builds a PMREM environment at runtime, procedurally,
so nothing binary is committed. There was no environment map anywhere before, so
every `metalness > 0` role had nothing to reflect and rendered dull grey — a
defect the code already documented against itself in `office/optimus.ts`, where a
whole material role was abandoned over it, and worked around in `modelX.ts` with
a fake emissive that this change deletes. Atmosphere remains the sole light
owner; the rig derives from the `LightingState` it already produced.

**Studio hardware exists.** There was no device concept anywhere in the product:
no type, no route, no state. `devices/types.ts` fixes a declaration/state/
capability/command contract that a smart light, a thermostat, a door sensor and a
charger all fit without a schema change, and both studios now carry a desk mic
and a computer speaker with deterministic simulated behaviour behind an adapter
seam a real API can occupy later. Reads are the demo and are open; commands are a
signed-in action and are kept off the read body entirely, because a shared cache
replaying a GET that turned a microphone on is exactly what the fail-closed
cache default exists to prevent.

**The ADS-B licence hole is closed.** `TERA_ADSB_ENDPOINT` accepted any URL, the
response was served publicly cacheable, and the attribution hardcoded adsb.lol
regardless of where the endpoint pointed — one env var away from republishing
non-redistributable data under an open-terms credit. The host is now allowlisted,
the credit is derived from the host actually configured, public cacheability is
conditional on redistributability, and a refused endpoint demotes to simulated
flights and says so in `degraded[]`. The gate is on the source, not the feature:
live aircraft and their detail cards stay open to anonymous visitors.

**The LA studio was never the smaller pack** — 16 rooms and 248 props against
SF's 4 and 28. Its deficit was fidelity per square metre: 98 of those props were
ceiling troffers, it bound no props to seats, placed none of the habitat kit, and
12 of its 16 rooms had no viewpoint. Density comes from new asset kinds rather
than more instances, because `furnish.ts` draws once per kind and folds colour
into the batch key, so repeat instances add nothing the eye can read.

**The interface stops being forty imperative mutations.** Every visibility
decision moves into a pure, tested `ui/chromeState.ts` and one applier, so the
chrome has coverage for the first time. Deleted: ~100 lines of CSS and two
bindings targeting elements that no longer exist, and a `body:has()` rule that
shifted the desktop layout by 160px for touch controls hidden there. Fixed: the
office picker tabs that drew their label and their badge on top of each other.
Added: a first-run flow, because the product is two verbs and neither was ever
stated on screen. Mobile is designed on its own terms instead of being the
desktop with things hidden — the plan view comes back, and the keyboard-only
shortcuts button is replaced by touch controls.

`arena/studioOps.ts` frames the whole thing as the multi-variable environment it
is, wrapping the same simulators the renderer drives rather than a headless copy.

Also removed `input/vehicle.ts`, which nothing but its own test imported.

Tests 385 -> 961, all passing. Typecheck, build, performance budgets across six
matrix cells, no-binaries, provenance, dependency licences, zero-config boot and
arena source hashes all green.
