feat: SFO, LAX, both bridges, a road that reads as a road, and aeroplanes that move
**The aeroplanes were stuck because the wire could not describe motion.** `WireAircraft` carried position, altitude and heading and nothing else, so the client could only interpolate between the last two observations: every aircraft replayed a segment it had already flown, arrived at the newest known point, and sat still until the next poll landed five to fifteen seconds later. The feed had the missing numbers the whole time and the server threw them away. Sampled live from `api.adsb.lol/v2/point` while writing this — `gs` ground speed, `track`, `baro_rate`, plus `r` registration and `t` type designator. They are on the wire now in SI, aircraft dead-reckon along their own track and correct toward the truth when a fix lands, and the click card an anonymous visitor gets says "B739 · N68834". That last part is the enrichment FR24 was wanted for, obtained from an ODbL feed we may actually republish. **SFO and LAX exist.** A new `engine/airports.ts` composes an airport from runways, taxiways, aprons and terminal masses, with markings drawn on a canvas rather than modelled; the pattern of the runways is what the eye recognises from altitude, long before any building does. SFO is the two crossing pairs on the bay fill; LAX is the four parallels either side of the terminal horseshoe, plus the Southland fields under the traffic that actually flies there. **The Golden Gate and the Bay Bridge are those bridges.** One kit in `engine/bridges.ts`, because a suspension bridge is a repeated tower, a catenary main cable, a series of hangers and a deck — so both are configurations rather than two private implementations. The Bay Bridge carries the real 2013 topology: two suspension towers west of Yerba Buena, one east, then the piered causeway. The freeway stopped being a wireframe overlay and became a road, with shoulders, a median, and lane markings as texture. **And the board got faster while all of that landed.** California went from 728,744 triangles and 562 draw calls to 391,169 and 371 — headroom from 2.8% to 47.8%. The Bay Area board is 506,550 triangles lighter than before this work. Two things paid for it: - `transmission: 0.08` on the aircraft cockpit glass. three.js runs a full transmission backdrop pass whenever any rendered material has transmission above zero, re-drawing the entire opaque scene into a second target every frame — so the city was rendering terrain, every block and every freeway piece TWICE. Measured by patching only that number in a copy of the built bundle: 703,267 tris / 562 draws with it, 398,608 / 371 without. The material was already `transparent: true, opacity: 0.86`, so it was buying nothing. - Flatness-adaptive terrain LOD, which collapses runs of lattice cells wherever the height and colour agree with the quad replacing them. The coastline is provably untouched — a patch collapses only when every point is on land and agrees about `park` — and a test asserts the drawn footprint matches the cell-by-cell area to 1e-6. `createTerrain` got *faster*: the vertices it stops emitting cost more than the flatness scan costs to run. **The budget now watches the boards this was built on.** There was no `bay-area` or `socal` cell — so SFO, LAX and both bridges all landed in frames nothing measured, which is how a cap you do not have looks from the inside. Both are in the matrix now with caps set from measurement, and the rationale lives in the harness because JSON cannot hold a comment. Two known defects ship with this, both recorded in TODO.md rather than hidden: - `bay-area.desktop` drops about one frame in twenty (p50 16.7, p95 33.3). It is desktop-only and not fill rate — mobile runs the same 2.26 M triangles at a comparable pixel count and holds 16.7 flat — which points at the 2048 shadow map desktop uses against handheld's 1024. Measured at the commit before this work with the same harness: identical p95 33.3. Pre-existing, and invisible until the cell existed. - The aeroplane glyph is still about 1.5x the Golden Gate's main span at chapter zoom, down from 2.5x. `GLYPH_MAX_SCALE` is 52 because the raw scale at the far end of the California orbit is 51.0 at a 60-degree field of view, and 26 — tried first — put the glyph at 0.0123 of the frame against the 0.012 where the wings stop resolving. The real fix is to clamp against the camera's focus distance rather than the aircraft's, which is a signature change. Tests 1020 -> 1137. Typecheck, build, eight budget cells, no-binaries, provenance, zero-config boot, dependency licences, arena source hashes and the UI smoke across two viewports and two access tiers all pass.

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.

The sky gets the things above the aeroplanes
Satellites, end to end: CelesTrak element sets behind the same TTL cache
the weather and the flights use, served as TLEs rather than as positions,
and propagated in the browser with SGP4.
Sending elements is the same trick `flights/plan.ts` plays and it has a
better excuse here — a TLE *is* the closed form, valid for days either
side of its epoch, so one cacheable fetch every six hours replaces a poll
and every viewer agrees about where everything is.
Two things are worth knowing about the shape of it:
- There is no region parameter. An aeroplane at 10,000 m is local and
a satellite at 550 km is above the horizon for a circle two thousand
kilometres across, so one catalogue serves both boards and the client
decides what is above its own horizon. Only the observer is per-city,
which is why `main.ts` shares the elements and rebuilds the catalogue.
- The layer draws on a dome, because it cannot draw anywhere else.
`world.metres(550_000)` is 21,000 scene units against a far plane at
3,000. Azimuth and elevation are real; the radius carries nothing.
Off by default: a clone that started pulling CelesTrak on `npm run dev`
would have volunteered somebody else's bandwidth for its onboarding.
Godmode gets the two dials that point at the sky rather than at the
light — fabricated traffic, which composes with a live ADS-B feed instead
of replacing it, and a switch for the satellite layer with a count beside
it. Both are god-only lies about the inputs, in the manner of the weather
override.
`satellite.js` is the second runtime dependency this package has taken.
Its entry point star-exports an Emscripten build that cannot be shaken
out, so `noWasmPropagator` in the Vite config cuts it: 308 kB of WASM
loader for a bulk propagator nothing calls, against 26 kB for the SGP4
that does the work.

Signing in puts people in the building
`member` and `anon` were told apart inside the office by the client and by nothing else. `access.ts` picked an `officeDepth`, `createOfficeScene` built a presence layer at full depth — and then nobody ever called `setPresence`, so both tiers rendered the identical empty room. A tier that changes nothing you can see is not a tier, and `routes/markers.ts` had already written down why one drawn only in the browser is worse than none: it is a UI hiding a control over a body the API hands to whoever asks. So the refusal happens on the server now. `GET /api/v1/offices/:id/presence` is the one route that always takes a session, whatever else the deployment is configured for. `markers.ts` serves its feed to anonymous callers when no feed is configured, on the grounds that there is nothing there to protect; that reasoning does not transfer, and the difference is the whole point — a marker is a company at an address and a presence is a person at a desk. The ordering inside the handler is the security property, not a detail. It resolves the viewer *before* it looks at the id, so an anonymous caller gets an identical 401 for a real office, a private one and one that was never created. Check the office first and 404-for-unknown against 401-for-known tells them apart perfectly, which is the enumeration oracle CONTRACT.md §6 forbids, wearing a different status code. Three requests and one `deepEqual` hold that down. `TERA_PRESENCE_DIR` is a second directory rather than a `people` field on the pack, and that is the design. `types.ts` says a `Presence` binds to a `seatId` and never to a coordinate so the geometry can be published while the people cannot — which buys nothing if both live in one file, because an operator who wants a public floorplan then has to strip the roster out by hand, and the first time they forget the leak is permanent. Two directories makes the safe thing the default thing. An office with no roster is 200 and empty, never 404: "no such office" and "nobody has told me who is in this one" are different problems with different fixes, and one 404 sends an operator after the wrong one. On the client, occupancy arrives after the room is on screen rather than before — the building is worth looking at while a second request is in flight. An API that answers is believed, including when it answers with nobody; an office where everyone has gone home is a real fact and overwriting it with invented people to liven up the demo is the one thing this must never do. An API that does not answer falls back to a fabricated roster, exactly as the markers do, because a clone with no server is the flagship case and a member shown the same empty room as a stranger has been told the tier means something when it does not. Those twenty-five people are invented and the page says so. `sample.ts` says it to a reader of the source; `#office-badge` now says "Sample occupancy — these people are invented" to the person looking at the room, and it is not suppressed when a real deployment's API merely happened to be down — that is exactly the case where a member would otherwise read invented names as their colleagues. Fabricated names at real desks look like a staff list, and a screenshot of one must not be possible to take without the caption. The floor plan marks the occupied desks, one colour for everybody where the scene has four: at three device pixels a hue is a guess. The plan answers "is anyone there" and the room answers "who, and what are they doing". Hovering a desk names them, and the readout reads as an address getting more specific — metres, then room, then person. server: 127 tests pass, 11 of them new. Client typechecks and builds; the office chunk absorbed the plan renderer and the entry chunk moved 2.3 kB for the sample roster. Checked in the browser at office.lumbridgecorp.com: FULL VIEW, the badge, figures at the benches, dots on the plan, and "3.7, 16.7 m · Alcatraz · Clementine Roux" under the pointer. |

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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |
