Two directories makes the safe thing the default thing.

Karti Tripathi	44c5a79424	SoCal, the whole bay, a moon, and gates that actually run 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.

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.

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 ·

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.

SoCal, the whole bay, a moon, and gates that actually run

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.
