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.

**Mateo Court**, a courtyard block in the Arts District — a third pack and
a third *kind* of building. Two office floors and a shed already existed,
so this is the plan the format had not been shown: a ring of rooms round
an open-air yard with **no corridor anywhere**. Every door opens onto the
yard, and the yard does the job a corridor does in the other two. It is
also the first pack whose `ceiling: null` means there is genuinely no
ceiling at any height rather than "take the lid off so the shot can see
in", and the first sited off the Bay Area board at all.
That last part needed a fix, not just a coordinate. `OFFICE_MARKERS` was
gated on `id === "sf"`, which was correct for exactly as long as every
office was in the Bay Area — it would have kept the Los Angeles building
off the Los Angeles board and pinned it to San Francisco's. The gate is
the board's own bounds now, which is the same question asked honestly.
Every door through the 0.25 m courtyard skin is 1.2 m rather than the
usual 0.9, and that is not a style choice: `blocked` inflates by the
walker's radius *and* the wall's thickness, so a 0.9 m leaf through a wall
that thick seals the room behind it while rendering perfectly. Two rooms
were sealed exactly that way on the first pass. The test says so, because
a well-meaning edit back to 0.9 for consistency would do it again.
**People move.** `samplePresenceAt` thinned the roster by hour, which
fixed a building that was full at 1 a.m., but everybody was still pinned
to their own desk all day. Occupancy is a hand-written booking table now:
meetings fill a room for a plausible length, the kitchen island fills at
lunch, and a `Presence` binds to a seat id — so "in a meeting" means
occupying a meeting-room seat, and the whole thing is choosing seat ids
rather than inventing positions.
The flood fill that checks a pack is walkable existed three times over.
One copy now, since the third is where a divergence lives.
**Films.** A new `office-dusk` reel — six hours over Lumbridge HQ catching
the moment the house lights take over from the sun, which is the one thing
only a time-lapse can show and which did not exist. The three existing
reels are re-rendered rather than re-captioned: `films.ts` in v4 named a
commit eleven behind HEAD, so the published reels were shot before there
were any clouds and before the city drew office pins.
Reviewers caught roughly a dozen false statements in the new prose across
these files — a room census that did not add up, a wall-thickness count,
a claim that every room has daylight when one does not, and a cost figure
saying `updateSun` runs once a second when it runs once a minute. The
consequential ones are fixed. In a codebase where the comments are the
design record, a confident wrong number is a defect.

**Clouds were invisible to everyone who had not wired up NWS.** The layer
took `currentWeather()?.cloudCover ?? 0`, and `currentWeather()` is null on
any deployment without a weather source — which is the default, and the
exact configuration this repo is held to: a stranger clones it, runs one
command, and gets a city with no account and no key. Their sky was
permanently, silently empty. `atmosphere.ts` already models a sky when
nobody has observed one; it now models cover too, an observed reading
still wins outright, and the clouds are there on a bare clone.
**Both offices are pins on the city, and clicking one walks you in.** Each
pack has carried a real `site` since the sun needed one, and that
coordinate was known to the lighting and to nothing else — a visitor
looking at the board had no way to tell that two of those buildings are
ones they can go inside. The coordinates move to a tiny eagerly-imported
`offices/sites.ts` that the packs import *from*, because a pack is a 25 kB
lazy chunk and the board wants its pins long before anybody opens a door.
A test asserts the pack and the table hold the **same object**, not merely
equal values: a drifted coordinate would put the marker on one building
and the sun on another and both would look entirely plausible.
**Aircraft bank into their turns.** The roll channel existed and was never
written, so every turn was flat. Bank comes from the coordinated-turn
relation against the measured turn rate, damped by a first-order lag so it
settles rather than oscillates, and clamped at 30° like a real limiter.
Six regression tests, because roll is the one channel that feeds itself —
position and heading are recomputed from the last two observations and
wash out a bad value, while a NaN in the roll would persist for the life
of the track.
That fed straight into a real defect: `AdsbFlights` substituted
`heading: 0` for records with no `track` field, which is harmless for a
symmetrical dart and is a **sustained full-scale artefact** once aircraft
bank — a target whose real heading is 200° reported as 0° reads as a 160°
turn and pins the roll at its limiter for as long as it is in the feed.
Those records are dropped now. An aeroplane the feed will not give a
heading for is one this layer cannot draw honestly.
**The office empties out overnight.** A full complement of seated people
at one in the morning, under house lights that came on because the sun is
down, was the least believable thing left in the room once the clock
became real. A live roster always wins — an API that says the building is
empty is telling the truth about the building.
**Robots go somewhere.** They pick real addresses — a seat, a room — and
turn to face the seat when they arrive, rather than stopping at a random
angle. Godmode gets an office section: house lights forced on or off or
following the sun, robots and ceilings toggled, with a readout.
**The bundle is split.** Entry chunk 758 kB to 208 kB, with three.js and
satellite.js in a vendor chunk that survives an app deploy instead of
being re-downloaded on every one. Rollup's 500 kB warning still fires and
should — it now points at three.js, where it is true, instead of at our
code, where it was pointing at three.js all along.
Reviewers caught two false geography claims in the new prose ("both
shipped buildings stand in San Francisco" — one is across the estuary at
Alameda Point) and several miscounted figures. Fixed. In a codebase where
the comments are the design record, those are defects.

**Shadows were the right size and pointed at nothing.** Last round fixed the
missing `updateProjectionMatrix()`, so the frustum finally became the size
every caller asks for — but nothing aimed it, and `sun.target` sits at the
world origin. A pack's origin is the **north-west corner of its slab**, so
for lumbridge-hq the box was off-centre by half the building: 14.4 m of a
48 m plate, about a third of the floor, fell outside the frustum and
neither cast nor received. Invisible while three's broken ±5 default made
shadows useless everywhere; obvious the moment they started working.
`SceneKitOptions` takes a `shadowTarget` now, both callers pass one, and
the light's target is added to the scene — which is the part that actually
matters, because `LightShadow.updateMatrices` reads `target.matrixWorld`
and an unparented `Object3D` is never reached by the traversal that
updates it. The sun is also placed relative to the target rather than the
origin, so light-to-target is exactly `sunDistance` for every direction,
which is the invariant each caller's `shadowNear`/`shadowFar` were chosen
against.
**`flights.ts` could not be tested, and that is why it was untested.** It
used a TypeScript parameter property — the one piece of TS syntax that
*emits code* rather than annotating a type — so Node's type stripping
refused the whole module. The bundler never cared, so nobody found out
until the first `node --test` file tried to import it. The module carrying
the worst bug this project has shipped was, by construction, the one
module that could not have a test. It has eleven now, including one that
fails if the live-aircraft repeat-skip is removed.
**Robots are on the plan panel** — a turned marker with a bow for heading,
in the one hue left that is neither the people-blue nor the camera-amber.
Review findings cleared across the four new sky/robot modules: a real
24 mm void at the ankle and an 8 mm hole through each forearm, a
per-frame allocation in the robot heading picker, a per-frame sort in the
starlink ranking, `uTime` growing unbounded until the cloud breath
quantises, and `DAY_REFERENCE`'s derivation which did not reproduce.
`createStarlinkMeshLayer` now takes a **board** radius — the same unit its
sibling takes — instead of a dome radius with nothing in the types to tell
them apart. That is the exact confusion that has already caused one real
bug here. `DOME_RADIUS_FACTOR` has one owner and is imported, not copied:
the points and the meshes must be on the same dome or a satellite that
grows geometry also jumps.
Several comments were wrong rather than merely stale — a fabricated claim
about `Object3D.clone`, a fabricated attribution to `Plan`, an inverted
`DoubleSide` argument, a triangle ledger citing a function that no longer
exists, and a defensive-call rationale that contradicted the paragraph
above it. In a codebase where the comments are the design record, those
are defects.

**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.

**Aircraft actually move now, and the reason they did not is the headline.**
`HttpFlights` holds a frozen snapshot between network refreshes and is
polled at 1 Hz, so a live feed handed the layer the same position five to
fifteen times and then jumped. `span` therefore measured the poll interval
rather than the gap between the two positions that differ, the teleport
test saw an airliner covering 36 units in a "second" against a ceiling of
8, and **every live track's history was wiped on every refresh** — so no
aircraft on the deployed site could ever grow a trail, however long
TRAIL_POINTS was set. Skipping the repeat fixes the motion and the trail
at once. Trails then go to 72 points / 240 s, which is about seventy
seconds of flying.
Three more defects in the same file, found while looking: trail
truncation dropped the segments nearest the aircraft (leaving a streak
with no aeroplane attached), MAX_TRACKS was declared and never enforced,
and one missing target deleted its whole trail. The buffer now uploads
only what it wrote, rather than 46 MB/s of untouched array.
**You can get above the constellation.** Dome to 1.05 board *radii* and
the orbit to 2.0 spans. Radii, not spans: scene space is centred on the
city and the Bay Area board runs forty kilometres down the peninsula, so
the furthest corner is 0.94 spans out where the half-diagonal is 0.65 —
sized off the half-diagonal the dome sat inside its own city. The far
plane goes to 4 spans to stop clipping the sky from off-centre chapters,
and `PointsMaterial` defaults `fog: true`, which was quietly dimming the
whole constellation with the city's haze.
**An office can say where it stands.** `Office.site` — lat, lng, height
above the ground outside, and the compass bearing the pack's −Z points
along — and with one it gets the same sun the city does, a sky, and a
horizon at `-elevation`. CONTRACT §4 reserved this as "a later
refinement"; it is taken up rather than overturned, and `daylight.ts`
computes no light of its own. It does the two things a room needs that a
map does not: turn the sun into the building's frame, and move the fog
outdoors before it greys out the far wall.
Two buildings now, and they are deliberately unalike: Lumbridge HQ 188 m
up a Transbay tower facing 205°, and **Frontier Valley**, a startup in a
hangar at Alameda Point — one room, 54 x 30 m, nine metres to the
trusses, four metres above reclaimed ground.
Floor-to-floor in the reference pack is now 16.8 m: the interstitial is
ten times a real one, so the space between the slabs is somewhere things
can hang. It is frankly not architecture, `PLENUM` is the one number to
change, and the file says so.
Also fixed, all found by review rather than by looking at the screen:
- `sun.shadow.camera.updateProjectionMatrix()` was never called, so
three's default ±5 unit box has been in force this whole time and
every `shadowExtent` this repo passes — including the city's ±752 —
has been silently ignored.
- A missing aircraft was kept alive by the new grace period and *drawn*,
so it froze in mid-air at full opacity for 32 s.
- Frontier Valley's mezzanine was a `Room`, which carries no height: its
slab lay on the concrete, its chairs floated 4.4 m over it, and its
balustrade fenced off a patch of ground floor. It is a `Level`.
- Overlapping floor slabs z-fought. The format permits overlap and
resolves later-first, so `shell.ts` now lifts a slab a hair per
earlier slab it overlaps — and by nothing at all in a pack, like the
reference office, whose rooms only ever abut.
- `switchOffice` bypassed the `entering` guard (leaking a whole scene
per double-click) and tore down the old room before knowing the new
one would load, with no way back.
Known and not fixed: raising MAX_SPAN to 30 s doubles the worst-case
re-base snap when a feed's gap shortens. It is bounded, pre-existing in
kind, and the fix wants carrying the live head into the next leg.

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.

Three things, all on the door people actually open. office.lumbridgecorp.com is
a link you send somebody, and a link somebody is sent is opened on a phone.
**The plan had no way in.** The stylesheet builds it a whole bottom-sheet layout
below 600px — full width above the rail, 38dvh tall, hover-only text dropped —
and the only thing that could open it was the `M` key, which on a phone is not a
control that is hard to find but a control that does not exist. The comment
above that layout says "it is still behind `M`, so it costs nothing until it is
asked for", and on a phone it could not be asked for. So there is a button, in
the one cluster a thumb reaches, at every width rather than only the narrow ones
— a control only a keyboard can reach is a control some people do not have, and
that is as true at 1920 as at 390. It is glyph-only, because the `M` hint beside
it already carries the word and two controls labelled "plan" in one bar is one
too many, and it carries `aria-pressed` for the same reason the chapter buttons
do: a toggle that does not look like its state is a button that appears to do
nothing on every second press.
**The disclosure was behind a hamburger.** "Sample occupancy — these people are
invented" lived on `#office-badge` inside `#panel`, and on a phone `#panel` is a
sheet that starts closed. The one sentence standing between twenty-five invented
people at real desks and a screenshot presented as a staff list was hidden, on
the device most likely to take the screenshot. It moves to `#source`, which is
where this page already says what on screen is and is not real, is fixed and
always drawn, and which the phone stylesheet itself calls "the one caption that
is never allowed to be dropped for space". It replaces the city's liveness line
while you are inside rather than joining it, because the markers, the sky and
the traffic are facts about a board behind you — and "live data" printed over
invented colleagues is the exact species of lie that wording was rewritten to
stop telling. It also needed a rule of its own: `.source` on a phone is one
nowrap ellipsised line, which rendered this as "sample occupancy · these people
…", a truncation that removes the only word that mattered. A disclosure cut off
mid-clause is worse than none, because it looks like a caption somebody bothered
to write and nobody goes looking for the rest.
**The room did not fit.** `camera.fov` is vertical, so visible width is
`distance * tan(fov/2) * aspect`, and a phone held upright has an aspect near 0.5
against the 16:9 those viewpoints were framed by eye against. At the same
distance that is a third of the width: the arrival shot put a thirty-four-metre
floor plate off the corner of the screen under a frame full of empty sky. The
pack was not wrong and the renderer was not wrong — the number meant something
else on that screen. `poseFor` now preserves the width the author framed, which
is the thing they were choosing; "everything in this building is somewhere in
this frame" is a statement about width, and the extra height a tall screen throws
in costs nothing. It only ever pushes back, never pulls in, so a window wider
than 16:9 is untouched.
The correction scales the whole offset from the target and not the ground
distance alone, and that is the entire fix rather than a refinement. Multiplying
only the distance does not step back from a shot, it flattens it: 32 m out and
14 m up became ninety-odd metres out and still fourteen up, a near-horizontal
squint at the edge of a floor plate stranded near the horizon. I built that
first and it was worse than the bug.
Checked on an iPhone 13 viewport and at 1920x1080 and 1440x900. Phone: the whole
floor centred at the authored angle with people at the benches, the disclosure
on two lines and complete, the button tapped open and the plan sheet up with
eight rooms named. Desktop 16:9 is pixel-identical — the correction is exactly 1
there — and the console is clean on all three.
Occupancy was fetched once, on the way in. Somebody sat down and you did not
find out until you left the office and came back, which for a view whose entire
subject is who is in the building is the point missed by one request.
`watchPresence` is `watchWeather`'s shape without the two pieces of judgement
that one needs and this does not: weather has to decide whether an observation
is too old to be honest about and whether it describes the place you are looking
at, and a roster is neither — it is true when it is served, and it is addressed
by office id, so it cannot arrive about somewhere else.
Thirty seconds, and the number comes from what the data does rather than from
what the network will stand. Ten minutes is right for weather because nothing
upstream of it moves faster; occupancy moves when a person stands up. Backoff
tops out at five minutes rather than the weather watch's hour, because the
difference between the two is what the user is doing while the box is down:
nobody is staring at the sky waiting for it to be redescribed, and somebody *is*
standing in a room they expect to see people arrive in. An hour of silence there
reads as a broken feature rather than as a quiet API.
Two things it does that the weather watch does not, both because this one runs
while a person is looking at the thing it describes. It stops dead while the tab
is hidden and asks again the moment it comes back — a backgrounded tab polling a
roster nobody can see is waste on both ends, and it is the commonest state a
long-lived office tab is in; coming back has to be immediate rather than at the
next tick, or you return to a floor up to thirty seconds stale at exactly the
moment you are looking hardest. And it publishes only on change, by signature
rather than by identity: every answer is a fresh array, so without the
comparison a still floor would rebuild its presence meshes twice a minute
forever.
The watch belongs to the visit and not to the page, which is `weatherWatch`'s
rule for a sharper reason — a roster is requested with a credential and names
people, so one left running after somebody stepped out to the city is a page
quietly asking about a room nobody is looking at. Stopped before the scene swap
in `leaveOffice`, so the last thing it can do is abort a request rather than
publish into a room already left, and stopped again in `mountCity`, which
disposes the office under it.
Checked in the browser, both exits. Standing in the office: one ask on arrival,
the next 31 s later under failure backoff, not a flood. Stepping out by the `O`
key on the office host (a real navigation) and by the scene swap on
`?view=office` (which is what actually exercises `stop()`): zero requests in the
following 45 s, in both.
`minimap.ts` is handed `deviceProfile().maxPixelRatio` and `officeMinimap.ts`
was not, so it defaulted to 2 and rendered a phone's floor plan at twice the
fill rate the city plan had already decided that handset could afford. Two 2D
canvases in one corner of one page disagreeing about what a phone is: exactly
the drift `deviceProfile` lives in a single file to prevent, and stage.ts says
so at the top. Mine to fix — it arrived with the plan two commits ago.
`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.
office.lumbridgecorp.com and tera.lumbridgecorp.com are one bundle behind two
names, and the office door had two ways of forgetting which one you came in
through.
The plan panel was the loud one. `createMinimap` is built per city, from
`city.world`, and nothing swapped it when you stepped inside — so the one piece
of chrome whose entire job is to answer "where am I" went on drawing the Bay
Area while the scene in front of it was a thirty-four-metre floor plate. Not
merely unhelpful: pointing at another county.
So there is a second widget for the other place. `officeMinimap.ts` reads the
`Plan` the scene was already built from — no second resolution pass, no geometry
re-derived — and draws it: room slabs, the walls as their `solid` runs only,
which leaves a gap at every door and arch because `Plan` had already split them
for the collider; a glazing hairline across each window, without which the
reference office's north edge simply is not there; furniture at its real
footprint from the asset registry, turned by its own yaw, so four benches of
twelve read as four benches of twelve; room names over a halo, because a room's
centroid is usually the middle of its own desks. Same corner, same `M`, same
camera footprint, same click-to-seek, same keyboard aim. The footprint is cut
against `level.floorY` rather than y=0, which is the same number on a one-storey
pack and a whole storey out on any other.
It is a second module rather than a mode inside the first because the two share
their shape and almost none of their content: one projects lat/lng through a
`World`, rasterises a coastline and a hillshade and follows the sun; this one is
already in metres and lives under a fixed interior rig where the sun does not
reach. One file would have been an `if (city)` at the top of every function.
It arrives in the office chunk, not the entry chunk. It reads prop footprints
off the asset registry, so it is downstream of the furniture catalogue that the
`await import()` in `loadOffice` exists to hold back; a value import in main.ts
would have pulled all of it forward and silently undone the split. So main.ts
takes the constructor as an argument and names the module type-only, and the
build agrees: officeMinimap is its own 10.3 kB chunk and the entry is unmoved.
The quiet one was the URL. Leaving the office swapped the scene and left the
address bar saying `office.` — which is the thing you copy, bookmark and send to
someone, and it took them somewhere other than what you were looking at. From
the `office.` host the exit is now a real navigation to the same hostname with
its first label swapped: the same string comparison that decided this was the
office door decides where the city is, so a deployment serving one name and not
the other gets an honest 404 on a name it chose not to serve rather than a
silent lie. `?city=` carries the metro across so stepping out into SoCal lands
in SoCal, and is read unconditionally because a deep link to a city is a
reasonable thing to want on its own. On `?view=office` there is no other host to
go to, so the scene swap stands and the query is dropped on the way out.
Checked against the production build with both real hostnames resolved at a
local static server: office.lumbridgecorp.com boots into the office with the
floor plan in the panel, the hover readout gives office metres and the room
under the pointer ("9.8, 16.7 m · Bernal"), `O` lands on tera.lumbridgecorp.com
showing the Bay Area, and the console is clean.
`liveData` was one flag meaning two unrelated things, and it was set to
`tier !== "anon"`. That reasoning does not survive asking what the data actually
is. Cloud cover over San Francisco is a reading from a government sensor. The
aircraft are broadcasting their positions, unencrypted, to anyone within range
who owns a forty-dollar receiver. Neither is withheld from anybody by anybody,
so neither is a thing an account can grant access to — and putting them behind a
sign-in cost the only moment that makes this project land: real fog rolling off
the Pacific onto a city you recognise, at the real time of day, on a first
visit. On an SSO-gated deployment it cost that moment for every visitor there
currently is.
So `liveData` splits. `liveEnvironment` is public and unconditional.
`liveMarkers` is asked for by everyone and granted by the server, because the
marker set is the one feed here that can carry something private — a company's
pipeline, a person's job search — and whether it is public is a property of the
deployment, not of a file in this repo.
`TERA_MARKERS_ACCESS` is therefore a server switch and its default is `members`,
which is the safe answer rather than the common one. The failure mode of getting
this wrong is silent: nothing throws, nothing looks broken, the data is simply
readable by the internet. An operator who wires real markers up gets the shut
door without having chosen it and has to say `public` out loud — and saying it
appends a line to `degraded[]`, so `/api/v1/health` reports that this box is
publishing its map without anyone having to go and read the env file. Same
reasoning as `TERA_ADMIN_SUBJECTS=*`.

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.

"sample data · fabricated, not real companies" sat in the corner of every load,
because no deployment has a markers source wired by default and the sample set
is therefore the overwhelmingly common case. A caption that is always on screen
stops being read after the first second, which is the opposite of what a
disclosure is for.
So the corner keeps only the rare half — "live data", which is genuinely worth
interrupting someone to say — and the fact that the markers are invented moves
to the two places someone actually looks: the boot card everyone passes through,
and the `?` card, which is one keypress away from any state the app can be in.
It did not go into a README nobody opens.

The right half of the screen was empty sky. It holds the board now, drawn flat,
with the footprint of the camera's own frustum on it — the one part of a minimap
that earns its place, because it answers "where am I looking from" without
leaving the shot. Click it, drag it, scroll it. It is a 2D canvas rather than a
second WebGL context, cached per city and redrawn only when something moved.
Night was black. Not dark — black: at 3 a.m. the coastline, the hills and the
bay were one shape, and the frame read as a failed render rather than as
darkness. The sky already had a floor for exactly this reason and nothing did
the equivalent for the ground, so the ground has one now. The moon still has to
be worth computing, so the gap between a moonlit night and a moonless one is
preserved rather than filled in.
Three tiers, resolved once in the new src/access.ts: anonymous, signed in,
admin. Anonymous gets the map and a public office — the shell, the furniture,
the named viewpoints, nobody home — built without the private objects rather
than with them hidden, because scene.traverse makes hiding a leak with a bow on
it. The time scrubber and the debug readouts are admin only, and admin is
granted by TERA_ADMIN_SUBJECTS on the server and inferred nowhere else. An
unreachable API means member, never god: the promise is "clone it and it works",
not "clone it and you are an administrator of a deployment you did not
configure".
Three things this run found and fixed rather than shipped:
- entryUrl came off the wire and went straight into an href with no scheme
check, and a CSP of script-src 'self' 'unsafe-inline' does not stop a
javascript: URL from navigating. One rejection point in access.ts now.
- A 5xx from /health was the same null as "no API at all" and therefore the
opposite conclusion. Eight seconds of tera-api restarting would have told
every anonymous visitor they were a member. A 5xx is an answer; it fails
closed.
- decodeURIComponent in cookieToken was the one path in auth/index.ts that
threw rather than returning ANONYMOUS, so one malformed cookie header from
an unauthenticated caller turned /api/v1/session into a 500.
Also: keyboard shortcuts, focus rings, a boot state instead of a blank 2.3
seconds, a collapsible panel under 900px, and no horizontal overflow at 375,
768, 1440 or 2560.

Six agents in parallel, and the two city packs independently reported the same
blocker: `focusRegions` and `coarseFactor` existed on the `City` type and
nothing implemented them. Uniform lattices would have been 2.9M points for
Southern California and 3.7M for the expanded bay. Both packs were unloadable
as written.
`buildAxis` is the answer, and it is honest about its limits: refinement is per
axis, not per rectangle, so a focus region sharpens its whole row *and* its
whole column. Two regions at opposite corners refine nearly everything between
them. Measured, not guessed — the bay went 0.53M points with one region and
1.64M with three, for detail nobody is looking at from a board this wide. One
region each, coarse factor ten, and the builds land at 3.8 s and 2.3 s.
Then three things that were only ever right because San Francisco was the only
city. `maxDistance: 340` and a 170-unit shadow box were constants tuned for a
230-unit board; the bay is 1003 units across and the camera physically could
not retreat far enough to frame it. Fog distances were scene units pinned to
the same assumption. And `minVisibilityM` defaulted to 4.5 km of honest
weather, which over ninety-four kilometres of bay correctly hides three
quarters of it — the night view was a black rectangle for a completely
reasonable reason. All three now derive from the board.
The moon is a real ephemeris and its light is a deliberate lie: 1.15, against a
physical ratio of one to four hundred thousand. What is being reproduced is
what a moonlit night looks like on a screen in a lit room.
The CI gate caught itself, which is the part worth keeping. Port 8431 was
already held by a server from an earlier session, so the boot check polled a
healthy stranger while the process it started died on EADDRINUSE. It now
refuses to run rather than pass.

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.

LSE is the third of the three, beside lumbridge-compute and lumbridge-bench: a
3D engine for walkable places. This first commit is the outside of the world —
San Francisco — plus the seams the inside will attach to.
The engine renders a City and a list of Markers and knows nothing else. It does
not know markers are usually companies and it will never learn that "rejected"
is red; that mapping lives in an adapter. Which is what lets one renderer serve
a private map, a public one, and a self-hoster with no Lumbridge account, none
of them a fork of the others.
Three things were designed around the licence rather than discovered after it,
because each one is a promise Apache 2.0 makes that is easy to break by
accident. No trademarks in the repo — logos are fetched at runtime, and
public/logos/ is gitignored. No OpenStreetMap-derived coordinates, which is why
every coastline in cities/sf.ts was traced by hand: Nominatim output is ODbL,
share-alike, and would attach to the whole pack. And no FlightRadar24 client —
their terms forbid scraping and redistribution, so flights are an interface
with a simulator and open community ADS-B behind it.
The privacy constraint and the licence constraint turned out to want the same
thing. Geocoded company positions and pipeline status both stay behind Workie's
API; the open repo holds the city and the renderer. The tempting shortcut —
commit an sf-companies.json — breaks both at once.
Ported out of Workie, where a 3D city engine had no business living. Workie's
/live is deleted rather than deprecated.
