karti	db074e9cf7	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.

karti	e41c90fe8d	Real weather, real aircraft, a heightfield off the main thread, and instruments Three things that were built and never connected, connected. The weather was already there. `observe()` has always taken a `WeatherObservation` and `main.ts` has always passed null, so the cloud, precipitation, visibility and marine-layer paths in atmosphere.ts had never run outside a test. The server already shipped NWS, met.no and Open-Meteo, all configured off. What was actually missing was that a single TERA_ORIGIN_LAT/LNG served one metro and lied to the other — so weather and traffic are per-region now, derived from the city's own bounds, and the Bay Area gets its fog while Long Beach gets its own sky. The route takes ?city= or a validated ?lat=&lng= and refuses to become an open geocoding proxy for the planet. The heightfield moved to a Worker. 2.3 s of blocked main thread at boot, and another ~950 ms of point-in-polygon on top of it: the park mask is filled in the worker now, and block placement samples four corners and only runs the exact test on a cell that straddles an edge — 8 buildings differ out of 185,036. createScene is async and takes a Stage as a consequence, and there is a main-thread fallback because "clone it and it works" has no exception clause. Spaces is a chunk you fetch when you reach for the door, not one everybody downloads. Same for the godmode tools. The entry chunk is 722 kB rather than 772; three.js is most of what is left and splitting it is a different job. Godmode is an instrument panel now rather than one slider: the date and the season, not just the hour, so the Meeus moon and the sun's seasonal arc become visible instead of merely correct; a weather override that says on screen when it is lying; a frame-time and draw-call readout; and a pose editor that emits a paste-ready Chapter block, which is the thing that makes adding New York cheap. Two blockers the review caught: - Every city switch leaked 8 GPU textures — one of them a 2048x2048 shadow map — and ~10.5 shader programs, and deleteTexture had never been called once in the app's lifetime. The renderer was being built per scene; it belongs to the canvas, for the life of the page. - An upstream fetch that threw rather than returning null skipped the cache stamp, so the TTL — the only rate limit on outbound calls — collapsed to one upstream request per inbound request, and the caller got a 500.

Karti Tripathi	d464459838	Spaces: the inside of the world, and a sun that is actually where it should be Ten agents wrote this in parallel against CONTRACT.md, which exists because the five design agents before them collided on fifteen blocking points — four files specified twice with incompatible contents, three separate backends for one box, and `Environment` exported twice meaning different things.

They cannot share one — San Francisco is ~94 m per scene unit with 3.6x vertical exaggeration and an office is 1 unit = 1 m — and the city is paused rather than disposed on the way in, because rebuilding its 336,864-point heightfield costs about a second on the way back out.

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.

Real weather, real aircraft, a heightfield off the main thread, and instruments

Three things that were built and never connected, connected.

**The weather was already there.** `observe()` has always taken a
`WeatherObservation` and `main.ts` has always passed null, so the cloud,
precipitation, visibility and marine-layer paths in atmosphere.ts had never run
outside a test. The server already shipped NWS, met.no and Open-Meteo, all
configured off. What was actually missing was that a single TERA_ORIGIN_LAT/LNG
served one metro and lied to the other — so weather and traffic are per-region
now, derived from the city's own bounds, and the Bay Area gets its fog while
Long Beach gets its own sky. The route takes ?city= or a validated ?lat=&lng=
and refuses to become an open geocoding proxy for the planet.

**The heightfield moved to a Worker.** 2.3 s of blocked main thread at boot, and
another ~950 ms of point-in-polygon on top of it: the park mask is filled in the
worker now, and block placement samples four corners and only runs the exact
test on a cell that straddles an edge — 8 buildings differ out of 185,036.
createScene is async and takes a Stage as a consequence, and there is a
main-thread fallback because "clone it and it works" has no exception clause.

**Spaces is a chunk you fetch when you reach for the door**, not one everybody
downloads. Same for the godmode tools. The entry chunk is 722 kB rather than
772; three.js is most of what is left and splitting it is a different job.

**Godmode is an instrument panel now** rather than one slider: the date and the
season, not just the hour, so the Meeus moon and the sun's seasonal arc become
visible instead of merely correct; a weather override that says on screen when
it is lying; a frame-time and draw-call readout; and a pose editor that emits a
paste-ready Chapter block, which is the thing that makes adding New York cheap.

Two blockers the review caught:

  - Every city switch leaked 8 GPU textures — one of them a 2048x2048 shadow map
    — and ~10.5 shader programs, and deleteTexture had never been called once in
    the app's lifetime. The renderer was being built per scene; it belongs to the
    canvas, for the life of the page.
  - An upstream fetch that threw rather than returning null skipped the cache
    stamp, so the TTL — the only rate limit on outbound calls — collapsed to one
    upstream request per inbound request, and the caller got a 500.

Spaces: the inside of the world, and a sun that is actually where it should be

Ten agents wrote this in parallel against CONTRACT.md, which exists because the
five design agents before them collided on fifteen blocking points — four files
specified twice with incompatible contents, three separate backends for one box,
and `Environment` exported twice meaning different things.

What landed: a Stage owning only the renderer and the loop, with the city and an
office as two scenes over it. They cannot share one — San Francisco is ~94 m per
scene unit with 3.6x vertical exaggeration and an office is 1 unit = 1 m — and
the city is paused rather than disposed on the way in, because rebuilding its
336,864-point heightfield costs about a second on the way back out.

Offices are data. `src/offices/lumbridge-hq.ts` is fifteen rooms and seventy-six
seats, and it is the file a self-hoster copies. Walls are a segment list with
1-D openings, so doors and windows are holes punched in a wall rather than
placed objects, and the pass that splits a wall around its openings hands the
walk-mode collider its segments for free.

The sun is real. `solar.ts` is a NOAA/Meeus implementation with no imports at
all — not even three.js — so time of day keeps working on a laptop in a field.
Verified against known values: 75.45 degrees at the June solstice in SF, 28.79
at December, sunset at 03:15Z. The first screenshot after wiring it was a black
rectangle, which turned out to be correct: it was midnight in San Francisco.

Presence binds to a seat id and never to a coordinate. The pack knows where
`eng-04` is; who is sitting in it is private data behind an API. Same shape as
the marker rule, one level in.

Two corrections to ARCHITECTURE.md are in here. Containment does not discharge
ODbL — publishing OSM-derived coordinates is Public Use of a Derivative Database
wherever the rows live, so the rule is about the geocoder (US Census, public
domain) and not the storage. And a person at a desk is not a Marker; markers are
geographic.

One contract gap surfaced only in a screenshot: two agents read `height` on a
viewpoint differently, so the establishing shot aimed at empty air fourteen
metres above the roof. It now means what the same field means for a city.
